Description

The present invention relates to a pump device, a control panel and a control board used in a building.

Pumping devices that supply water to buildings have been known for some time. As such a pump device, for example, a fire extinguishing pump device that supplies water to a sprinkler or the like in the event of a fire (see, for example, Patent Document 1), a water supply pump device that supplies water to a faucet, a shower head, or the like, an air conditioning pump for heating or the like. Devices and self-priming pump devices for snow removal are known.

In such a pump device, if the down time is long, there is a risk that parts formed of the metal material of the pump will rust, and the scale in which inorganic salt compounds such as calcium, magnesium and silica contained in water are precipitated will be present in the pump. May occur in. If these rusts and scales occur in the pump, the rotating body such as the impeller and the rotating shaft may stick to the fixed body such as the casing, and the rotation may be hindered. If the pump device is driven in this state, an overcurrent may occur in the motor.

Therefore, periodic inspection operation is required to prevent the rotating body from sticking and to detect the function and failure of the pump device.

Japanese Patent No. 6442338

However, since it is left to the user to carry out the periodic inspection operation of the pump device described above, there is a possibility that the periodic inspection operation will not be carried out. Further, since it is difficult for the manager of the manufacturer, the fire department, or the like to grasp the history information of the inspection operation, there is a problem that the user cannot be urged to perform the inspection operation. For example, when the pump device is a fire extinguishing pump device, the inspection operation is important because it is required to be able to operate normally in the event of a fire. Therefore, for example, it is conceivable to perform maintenance operation by forcibly and periodically driving the pump device, but depending on the structure of the building, noise and vibration may be disliked, and the pump device is forcibly and. It may be difficult to drive the pumping device on a regular basis.

Further, the same problem occurs not only in the inspection operation but also in the case where the specific operation of the pump device is manually performed.

Therefore, an object of the present invention is to provide a pump device, a control panel, and a control board that can promote a specific operation.

It is provided with a control unit that counts the integrated value of the stop time of the pump unit after the end of the inspection operation and gives a warning when the integrated value exceeds the threshold value.

According to one aspect of the present invention, the control panel drives the pump unit and a storage unit that stores a threshold value that is the stop time of the pump unit until the inspection operation is required, and after the end of the previous inspection operation. It is provided with a control unit that counts the integrated value of the stop time of the pump unit and gives a warning when the integrated value exceeds the threshold value.

According to one aspect of the present invention, the control board drives a storage unit that stores a threshold value, which is the time required for a specific operation of the pump unit, and the pump unit, and ends the previous specific operation. A control unit that counts the integrated value of the later elapsed time or the stop time of the pump unit and gives a warning when the elapsed time or the integrated value exceeds the threshold value, and the storage unit and the control unit are mounted.

The control board 46 is configured by, for example, mounting a control unit 41, a storage unit 43, a communication unit 45, and a terminal unit 48 on a single substrate 46a. The housing 47 houses the control board 46 inside, and arranges the input device 42 and the notification unit 44 on a part of the outer surface. Further, the housing 47 houses equipment 38 such as a power transformer, a current transformer for current measurement, an electromagnetic contactor, and a circuit breaker for wiring.

The control unit 41 is connected to the motor 22 and the pressure detector 33 via the signal line 99. The control unit 41 is electrically connected to the input device 42, the storage unit 43, the notification unit 44, and the communication unit 45 via a signal line 99 such as a bus line.

The control unit 41 is formed so that the motor 22 can be driven. The control unit 41 is formed so that the motor 22 can be driven when it is determined that a fire has occurred. As a specific example, when the control unit 41 receives the start signal of the pump unit 12 issued from the fire judgment device 301, the control unit 41 drives the motor 22 according to the program stored in the storage unit 43.

The control unit 41 has a calendar function capable of managing the date and a clock function capable of managing the time. The control unit 41 has a counter function for counting the elapsed time elapsed after the pump unit 12 is driven. The control unit 41 performs a specific operation of the pump unit 12, and stores in the storage unit 43 the elapsed time elapsed after the drive stop of the pump unit 12 counted by the counter function after the drive stop of the pump unit 12 in this specific operation. It has a function. Here, the elapsed time elapsed after performing the 12 specific operations of the pump unit means, for example, after performing the inspection operation of the pump unit 12 as a specific example after performing the specific operation last time. The time, or the time when the pump unit 12 is stopped.

Here, the time when the pump unit 12 is stopped (stop time) is an integrated value of the energization time when the control unit 41 of the control panel 18 which can be estimated to be the maximum stop time which may be stopped is energized. As an example, the integrated value of the stop time when the pump unit 12 is substantially stopped can be given. Further, the integrated value of the stop time when the pump unit 12 is substantially stopped is, for example, a value obtained by subtracting the energization time of the pump unit 12 to the motor 22 from the integrated value of the energization time when the control unit 41 is energized. is there.

The control unit 41 has a function of transmitting information on the abnormality to the notification unit 44 when an abnormality occurs in the pump unit 12. The control unit 41 is formed so that history information such as the time counted by the counter function and the drive information of the past pump unit 12 can be transmitted to the communication unit 45 based on the instruction input by the input device 42.

The input device 42 is formed so that information such as a date and time and a command can be input. The input device 42 is formed so that the input information can be transmitted to the control unit 41.

In the storage unit 43, a predetermined time until the inspection operation, which is a specific operation, and a value for evaluating the pump unit 12 at the time of the inspection operation are stored as threshold values. Here, the inspection operation is a periodic inspection of the pump unit 12 accompanied by a drive stop of the pump unit 12. For example, a plurality of inspection operations of the pump unit are set. Therefore, a plurality of threshold values, which are predetermined times until a plurality of inspection operations are performed, are stored in the storage unit 43.

As a specific example, the inspection operation includes a first inspection operation and a second inspection operation. The first inspection operation is, for example, a manual inspection. The first inspection operation is, for example, a legal inspection required for a fire extinguishing pump device. The first inspection operation is required to be performed, for example, when a predetermined time has elapsed from the previous first inspection operation. In other words, it is a statutory inspection that defines the number of inspections to be performed every predetermined period, such as once a year. Alternatively, it is determined that the first inspection operation is performed, for example, when the integrated value of the time when the control panel 18 is energized has elapsed a predetermined time since the previous first inspection operation. For example, the first inspection operation is performed every time the user operates the input device 42 to input a command for the first inspection operation. For example, in the first inspection operation, the pump unit 12 is driven for a predetermined time, the deadline lift during the deadline operation, the voltage and current supplied to the motor 22 during the deadline operation, the rated lift during the rated load operation, and the rating. The voltage and current supplied to the motor 22 during load operation are detected. Further, in the first inspection operation, for example, the automatic on-off valve 15 is opened during the rated load operation, and water is drained through the branch pipe 15a. The automatic on-off valve 15 may be opened to drain water even before and after the deadline operation of the first inspection operation.

The second inspection operation is an inspection performed manually or automatically, for example, a self-inspection or a maintenance operation. In the second inspection operation, for example, the stop time of the pump unit 12 from the previous second inspection operation, and more specifically, the integrated time of the time when the motor 22 is not energized from the previous second inspection operation is predetermined. It is required to perform the operation manually before the time has elapsed, or to perform the integration automatically when the integrated time elapses. For example, the second inspection operation is performed by the user operating the input device 42 to drive the pump unit 12, or the control unit 41 driving the pump unit 12. For example, the second inspection operation is an operation for detecting the deadline lift during the deadline operation, the voltage and the current supplied to the motor 22 during the deadline operation. The automatic on-off valve 15 may be opened to drain water before and after the deadline operation of the second inspection operation.

Further, the plurality of threshold values include a first threshold value, a second threshold value, and a third threshold value. The first threshold value is set as the time of the pump unit 12 from the time after the previous first inspection operation to the time when the next first inspection operation is performed. The second threshold value is set as the time of the pump unit 12 from the time after the previous second inspection operation to the time when the next second inspection operation is performed.

The third threshold value is set as a normal value of the detected value detected as the operating status of the pump unit 12 in each inspection operation. For example, the third threshold is, for example, the deadline lift during the cut-off operation when the pump unit 12 is normal, the voltage and current supplied to the motor 22 during the cut-off operation, the rated lift during the rated load operation, and the rated load operation. The voltage and current supplied to the motor 22 at the time.

Further, the storage unit 43 stores, for example, any one of the plurality of threshold values as non-rewritable. For example, the storage unit 43 is set to be non-rewritable after the first threshold is stored by the manufacturer of the pump device 1, and the second threshold is set to be rewritable to the value input by the input device 42. Will be done. The settings related to the rewriting of the first threshold value and the second threshold value of the storage unit 43 are set by, for example, processing the program or the like stored in the storage unit 43 by the control unit 41.

The storage unit 43 functions as a counter memory for the counter function of the control unit 41. Further, the storage unit 43 stores, for example, a starting pressure for starting the pump unit 12, a deadline lift during the deadline operation, a control program for the pump unit 12 at the time of a fire and in each inspection operation, and the like.

Further, the storage unit 43 is provided with an external personal computer that transmits information on the pump device 1 such as the identification number, model, and position information of the pump unit 12, information and results of each inspection operation, and a warning of the inspection operation. Information and the like of an external terminal 90 such as a computer or a tablet terminal are stored.

When an abnormality occurs in the pump unit 12, the notification unit 44 is formed so that the abnormality can be notified to the outside based on the information transmitted from the control unit 41. The notification unit 44 is a display unit that displays information. The notification unit 44 includes, for example, a lamp that displays information by lighting or blinking, a sound that notifies information to the outside by sound, and a display that displays information.

The communication unit 45 is configured to be able to send and receive information to and from the outside. For example, the communication unit 45 outputs the information transmitted from the control unit 41 to the outside wirelessly or by wire. For example, the communication unit 45 transmits information to the external terminal 90. In other words, the control unit 41 transmits information to the external terminal 90 via a network such as the Internet, LAN (Local Area Network), wireless or wired cable, etc. via the communication unit 45, and transmits the information to the external terminal 90. Display it. It should be noted that communication can be performed to the management center or the like by wire via the terminal unit 48 without using the communication unit 45. For example, if two different terminals are non-voltage a contacts and the contacts are turned on, it is possible to notify that a problem such as an overcurrent has occurred. In this case, in order to notify other events such as insufficient pressure and electric leakage, it is necessary to provide as many terminals as the number of events to be distinguished.

For example, the function of displaying information on the external terminal 90 is achieved by processing by the processor of the external terminal 90. The external terminal 90 is, for example, a display unit that displays information related to inspection operation. Further, here, the external terminal 90 manages, for example, a first external terminal 91 that the user has at a place away from the pump device 1, an administrator other than the user, a manufacturer of the pump device 1 as a specific example, and a building. The management center and the second external terminal 92 owned by the manager who supervises or manages the pump device 1 and the fire extinguishing equipment 100 of an external organization such as a fire station or a disaster prevention center.

Further, the control unit 41 has the following functions (1) to (3).

(1) A function of performing the first inspection operation of the pump unit 12 and transmitting the status of the first inspection operation to the outside.

(2) A function of performing the second inspection operation of the pump unit 12 and transmitting the status of the second inspection operation to the outside.

(3) A function that warns of inspection operation.

Next, the functions (1) to (3) possessed by the control unit 41 will be described.
The function of (1) is that when a command to perform the first inspection operation is input by the input device 42, the pump unit 12 is first inspected for a predetermined time and the detected value detected by the operation of the pump unit 12. Based on the third threshold value, it is determined whether or not the pump unit 12 is normal, and when a value that may damage the equipment, for example, the current is not normal, the function is to stop the energization of the motor 22. Further, the function (1) is a function of transmitting the information of the first inspection operation and the status of the first inspection operation such as the result of the first inspection operation to the external terminal 90.

A specific example of the function of (1) will be described below. As a specific example of the function of (1), first, the control unit 41 determines whether or not a command for performing the first inspection operation has been input by the input device 42. Then, when it is determined that the command for performing the first inspection operation is input by the input device 42, the control unit 41 performs the cutoff operation and the rated load operation based on the control program of the pump unit 12 stored in the storage unit 43. The pump unit 12 is operated for a predetermined time.

Then, the control unit 41 detects the cut-off head (pressure) detected by the pressure detector 13b during the cut-off operation, the voltage and current supplied to the motor 22 during the cut-off operation, and the pressure detector 13b during the rated load operation. The rated head and the voltage and current supplied to the motor 22 during rated load operation are detected. Then, the control unit 41 compares the third threshold value with each of the detected detected values, determines whether or not the detected value is a normal value, and a value that may damage the equipment, for example, the current is not normal. In that case, the energization of the motor 22 is stopped.

The control unit 41 stores the information and the result of the first inspection operation in the storage unit 43. The information of the first inspection operation is, for example, the date and time when the first inspection operation was performed detected by the calendar function and the clock function, and the counter function counts from the time when the first inspection operation was performed last time to the time when the first inspection operation is performed. It is the integrated value of the time taken and the number of days elapsed from the day when the first inspection operation was performed last time. The result of the first inspection operation is a detection value of pressure, voltage, current, etc. detected during the first inspection operation, a judgment result of whether or not the detected value is a normal value, and the like.

The control unit 41 transmits the information of the first inspection operation and the result of the first inspection operation to the external terminal 90 by the communication unit 45. As a specific example, the control unit 41 transmits the information of the first inspection operation and the result of the first inspection operation to the first external terminal 91 and the second external terminal 92.

Further, the control unit 41 has elapsed from the previous first inspection operation counted by the counter function from the time when the first inspection operation was performed last time to the time when the first inspection operation was performed after the first inspection operation was performed. Reset the elapsed time.

The function of (2) is when a command to perform the second inspection operation is input by the input device 42, or when the integrated value of the stop time of the pump unit 12 counted by the counter function exceeds the second threshold value. The pump unit 12 is subjected to the second inspection operation for a predetermined time, and based on the detection value detected by the operation of the pump unit 12 and the third threshold value, it is determined whether the pump unit 12 is normal or not, and there is a risk of equipment damage. This is a function of stopping energization of the motor 22 when a certain value, for example, a current is not normal. Further, the function (2) is a function of transmitting the information of the second inspection operation and the status of the first inspection operation such as the result of the second inspection operation to the external terminal 90.

A specific example of the function of (2) will be described below. As a specific example of the function of (2), first, the control unit 41 determines whether or not a command for performing the second inspection operation has been input by the input device 42. When a command to perform the second inspection operation is input by the input device 42, the control unit 41 operates the pump unit 12 for a predetermined time by the deadline operation based on the control program of the pump unit 12 stored in the storage unit 43. drive.

If it is determined by the input device 42 that the command to perform the second inspection operation has not been input, the integrated value of the stop time of the pump unit 12 counted by the counter function after the previous second inspection operation is the second threshold value. Judge whether or not it exceeds. When it is determined that the integrated value of the stop time of the pump unit 12 counted by the counter function after the previous second inspection operation exceeds the second threshold value, the control unit 41 of the pump unit 12 stored in the storage unit 43 The pump unit 12 is operated for a predetermined time by the deadline operation based on the control program.

Then, the control unit 41 detects the cut-off head (pressure) detected by the pressure detector 13b during the cut-off operation, and the voltage and current supplied to the motor 22 during the cut-off operation. Then, the control unit 41 compares the third threshold value with each of the detected detected values, and determines whether or not the detected value is a normal value.

The control unit 41 stores the information and the result of the second inspection operation in the storage unit 43. The information of the second inspection operation is, for example, the date and time when the second inspection operation was performed detected by the calendar function and the clock function, and the counter function counts from the time when the second inspection operation was performed last time to the time when the second inspection operation is performed. It is the integrated value of the stopped time and the number of days elapsed from the day when the second inspection operation was performed last time. Further, the result of the second inspection operation is each detected value of pressure, voltage, current, etc. detected during the second inspection operation, a judgment result of whether or not the detected value is a normal value, and the like.

The control unit 41 transmits the information of the second inspection operation and the result of the second inspection operation to the external terminal 90 by the communication unit 45. As a specific example, the control unit 41 transmits the information of the second inspection operation and the result of the second inspection operation to the first external terminal 91.

Further, the control unit 41 resets the integrated value of the stop time counted by the counter function from the time when the second inspection operation is performed last time to the time when the second inspection operation is performed when or after the second inspection operation is performed. ..

The function (3) is a function for giving a warning regarding the inspection operation, and specifically, is a function for notifying the outside of information prompting the inspection operation when the inspection operation is not performed for a predetermined time.

A specific example of the function of (3) will be described below. As a function of (3), first, the control unit 41 performs a manual inspection operation, and as a specific example, at least the previous first inspection operation of the first inspection operation in which a first threshold value that cannot be changed by the user is set. Occasionally, at least one of the elapsed time counted by the counter function after the pump unit 12 is stopped and the remaining time until the first inspection operation obtained from the integrated value and the first threshold value is performed, preferably both. Ask for. Then, the control unit 41 displays information on at least one of the elapsed time and the remaining time until the first inspection operation is performed, preferably both, on the notification unit 44.

In addition, the control unit 41 determines whether or not the elapsed time counted by the counter function has exceeded the first threshold value since the first inspection operation was performed last time. If the elapsed time counted by the counter function exceeds the first threshold value since the first inspection operation was performed last time, the control unit 41 determines that the first inspection operation is necessary. The control unit 41 gives a warning by displaying a warning to the effect that the first inspection operation is to be performed by the notification unit 44.

In addition, the control unit 41 sends a warning to perform the first inspection operation and the identification number, type, and position information of the pump device 1 stored in the storage unit 43 to at least the second external terminal 92, preferably the second. 1 The information is transmitted to the external terminal 91 and the second external terminal 92. That is, the control unit 41 transmits to the user and the administrator a warning that the first inspection operation needs to be performed and information on the pump device 1 that performs the first inspection operation.

The warning destination to which the control unit 41 gives a warning is transmitted based on the information of the external terminal 90 stored in advance in the storage unit 43. A part of the warning destination to which the control unit 41 gives a warning is set so that it cannot be rewritten by the user. In the present embodiment, at least the administrator's second external terminal 92 is set so that the user cannot rewrite it as a warning destination.

According to the pump device 1 used in the fire extinguishing equipment 100 configured in this way, the elapsed time from performing the first inspection function manually performed to the next performing the first inspection function is integrated. Then, when the accumulated elapsed time of the pump unit 12 exceeds the first threshold value, the accumulated elapsed time to the user's first external terminal 91 and the administrator's second external terminal 92 such as the manufacturer or the management organization is the first. Send information that exceeds the threshold. As a result, it is possible to warn the user and the manager such as the manufacturer and the management organization that the first inspection operation has not been performed even after a predetermined time has elapsed and that the first inspection operation is required. That is, the user and the administrator can grasp whether or not the first inspection function is implemented. In particular, since the first inspection operation is a manual inspection operation, there is a risk of forgetting to carry out the inspection operation. However, according to the configuration of the pump device 1, enlightenment and management of the inspection operation. Can instruct the person to comply with the inspection operation.

In addition, when the first inspection operation is a mandatory operation such as a legal inspection operation, the inspection operation can be notified to the user and the administrator can manage or monitor the user. Can be encouraged. In particular, when the pump device 1 is a fire extinguishing pump device, it is possible to prevent the pump device 1 from being stuck due to rust, scale, or the like due to a long stop, and the pump device 1 cannot be started in the event of a fire. Further, since it is possible to prevent the pump device 1 from being in a non-startable state, it is possible to prevent an overcurrent from flowing to the motor 22.

Further, since the control unit 41 transmits the information and the result of the first inspection operation and the second inspection operation to the user and the manager, the user and the manager can grasp the inspection status.

Further, the control unit 41 receives a command to perform the second inspection operation by the input device 42, or the integrated value of the stop time of the pump unit 12 counted by the counter function after the previous second inspection operation is the second. If the threshold value is exceeded, the second inspection operation is performed. In particular, when the integrated value of the stop time of the pump unit 12 counted by the counter function after the previous second inspection operation exceeds the second threshold even if the command for performing the second inspection operation is not input by the input device 42. By performing the second inspection operation, the pump device 1 is operated in a shorter period than the first inspection operation such as legal inspection. As a result, rust, scale, and the like can be suppressed as much as possible from adhering to the inside of the pump 21, so that the life of the pump unit 12 can be improved and the failure of the pump device 1 in the event of a fire can be suppressed as much as possible.

Further, when the inspection operation such as the first inspection operation and the second inspection operation is performed, the control unit 41 resets the integrated value of the elapsed time after the previous inspection operation or the stop time of the pump unit 12, so that the integration is performed. You can prevent forgetting to reset the value.

As described above, according to the pump device 1 according to the embodiment of the present invention, when the integrated value of the stop time of the pump unit 12 after the inspection operation of the notification unit 44 or the external terminal 90 exceeds the threshold value, the control unit When 41 displays a warning, inspection operation can be promoted.

The present invention is not limited to the above-described embodiment. For example, in the above-described example, the control unit 41 performs the second inspection operation when the integrated value of the stop time of the pump unit 12 counted by the counter function after the previous second inspection operation exceeds the second threshold value. I explained, but it is not limited to this. For example, the control unit 41 is a case where the integrated value of the stop time of the pump unit 12 counted by the counter function after the previous second inspection operation exceeds the second threshold value, and is subsequently stored in the storage unit 43 in advance. When the set time is reached, the second inspection operation may be performed. The pump device 1 having such a configuration is effective when it is desired to perform the inspection operation avoiding the night because vibration and noise are generated when the pump device 1 is operated when the inspection operation is automatically performed. is there.

Further, in the above-described example, the example in which the second inspection operation is performed by the deadline operation has been described, but in order to prevent noise and vibration as much as possible, the second inspection operation may be configured so that the operation is not performed until the deadline lift. As a specific example, in the second inspection operation, in order to prevent the rotating body in the pump 21 from sticking, the motor 22 is energized, and when the pressure fluctuation is detected by the pressure detector 13b after the energization, the pump 21 is driven. It may be a judgment and an end operation. That is, the second inspection operation may be an operation for the purpose of preventing the pump 21 from sticking, and by stopping when the pump 21 is driven, vibration and noise may be prevented as much as possible.

Further, in the above-described example, the configuration of the pump device 1 having a calendar function, a clock function, and a counter function has been described, but the present invention is not limited thereto. For example, the calendar function may increase the power consumption of the battery and increase the cost of the pump device 1, so that the pump device 1 may not have the calendar function. In the case of such a pump device 1, the above-mentioned inspection operation information and results, etc., do not include the elapsed days, inspection dates, etc., but the elapsed time, stop time, etc. obtained by the clock function and counter function. Only information on the time of. Similarly, the counter function may be used to obtain only the integrated value of the stop time of the pump unit 12 without having the clock function. Furthermore, it does not have a clock function and a counter function, only a calendar function is provided, the number of stop days is accumulated instead of the stop time, and the information and results of the inspection operation are the elapsed days, the stop days, the inspection date, and so on. The information may be only the date.

Further, in the above-mentioned example, the configuration in which the sprinkler 211 is provided as the fire extinguishing equipment 100 has been described. However, the sprinkler 211 is provided with a closing valve on the sprinkler head 211b and is always open even if it is open in the event of a fire. It may be an open type. For example, when an open type sprinkler head 211b is used, an on-off valve is provided on the sprinkler 211, and the first inspection operation and the second inspection operation are manually performed, and the on-off valve is closed when the inspection operation is performed. do it. Further, the fire extinguishing equipment 100 may be configured to use a foam fire extinguishing equipment or a water spray fire extinguishing equipment instead of the sprinkler 211.

Further, in the above-described example, the pump device 1 is a fire extinguishing pump device, and the example in which the pump device 1 is used for the fire extinguishing equipment 100 has been described, but the present invention is not limited thereto. For example, the pump device 1 can be applied to other equipment and pump devices.

For example, the pump device 1 may be configured to be used for equipment that is expected to be stopped for a long period of time depending on the season, for example, air conditioning equipment such as heating. When such an air-conditioning pump is used for heating, for example, an inspection operation is performed except in winter in order to prevent deposits from sticking to the vicinity of the mechanical seal by stopping for a long period of time. May be. Further, since such a pump device for heating is frequently operated in winter, it may be configured not to perform inspection operation in winter. Alternatively, when performing an inspection operation of a heating pump device in winter, for example, when the pump device for heating is not continuously operated for a predetermined time, the number of stop days or stop time is accumulated, and the accumulated number of days or time exceeds the threshold value. In that case, it may be configured to perform an inspection operation. Further, when the stop time between operations without inspection is shorter than a predetermined time, the integrated value of the stop time may be reset.

Further, for example, the pump device 1 may be configured to be used for snow-melting equipment. When a pump device is used to pump water for snow removal in such a snow removal facility, for example, air conditioning is performed to prevent deposits from sticking to the vicinity of the mechanical seal by stopping for a long period of time. Similar to the case where the pump device is used for the equipment, the inspection operation may be performed except in winter. Further, such a pump device for removing snow may be configured to perform an inspection operation even during a period when there is little snow in winter. For example, in the case of performing an inspection operation of a pump device for snow removal in winter, if there is no continuous snowfall and the operation is not performed for a predetermined time, the number of stop days or stop time is accumulated and the accumulated number of days or time is accumulated. When the threshold value is exceeded, the inspection operation may be performed. In addition, some pump devices for snow removal are installed outdoors, and in order to prevent freezing, the integrated value or elapsed stop time is set to a threshold value shorter than the stop time of the pump unit where freezing is expected. The inspection operation may be performed when the time exceeds the threshold value. For example, the specific operation in this case is not an inspection operation but an operation by a signal input by a snowfall sensor at the time of snowfall or an operation by a signal input by a temperature sensor near the freezing temperature.

Further, the pump device 1 may have a configuration used for a water supply device for drinking water. For example, if regular inspections are required by law, such as once a year, the calendar function will add up the number of days that have passed since the last regular inspection, and the number of days for regular inspections has passed. The information may be warned to the outside when or just before the elapse. Further, when a pump device is used for other equipment as described above, when a specific operation such as an inspection operation is performed, the automatic on-off valve 15 is opened and the pump device 1 is driven while draining water. May be good.

Further, in the above-described example, the warning of the inspection operation has described the configuration in which only the first inspection operation is performed, but the warning is not limited to this. For example, the second inspection operation is also manually performed, and when the integrated value of the stop time of the pump unit 12 exceeds the second threshold value after the second inspection operation, the function (3) controls the operation. The unit 41 may be configured to warn at least the user's first external terminal 91, preferably the first external terminal 91 and the second external terminal 92 that the second inspection operation needs to be performed.

Further, in the above-described example, an example including the first inspection operation and the second inspection operation has been described as the inspection operation, but the present invention is not limited to this, and there may be only one inspection operation, and three or more inspections are performed. The configuration may include operation. Further, the specific operation is not limited to the inspection operation, and the specific operation may of course include an automatic operation as long as it has at least one specific operation to be performed manually. For example, the inspection operation may further include a third inspection operation. As a specific example, in the third inspection operation, when a command to start the inspection operation is transmitted from the external terminal 90, the communication unit 45 receives the command and the control unit 41 drives the pump unit 12.

Further, in the above-described example, the configuration for displaying or transmitting the information and result of the inspection operation and the warning to the notification unit 44 and the external terminal 90 has been described, but the configuration is not limited to this, and the configuration for warning other devices is used. There may be. That is, as long as the information about the inspection operation can be transmitted to the outside, the mode can be appropriately set.

Further, in the above-described example, an example in which the automatic on-off valve 15 is provided and can be opened and closed to drain water to the drain port 15b has been described. For example, the automatic on-off valve 15 is gradually opened and closed to prevent water hammer. It may be opened and closed to increase or decrease the opening degree.

Further, in the above-described example, the configuration for obtaining the elapsed time for performing the periodic inspection, which is the first inspection operation, by counting by the counter function has been described, but the method for counting the elapsed time can be appropriately set. For example, the elapsed time may be estimated by the integrated value of the energization time to the control unit 41 if the periodic inspection can be surely performed within the period specified by the law, and the number of days is counted by the calendar function. There may be.

Further, in addition to the above-mentioned example, the current value at the time of deadline is stored in the storage unit 43 in advance, and when the rotating body of the pump 21 is stuck, the detected current value of the motor 22 is stored in the storage unit. When the value becomes larger than the current value stored in 43, the pump 21 may have a function of determining that the pump 21 is stuck. Further, for example, as a function of determining a defect such as sticking of the pump 21, the automatic on-off valve 15 is operated in an open state, the automatic on-off valve 15 is gradually closed, and the pressure is detected with the automatic on-off valve 15 closed. However, if the detected pressure is lower than the pressure at the time of the deadline stored in the storage unit 43 in advance, the pump 21 may be determined to be stuck. That is, if the automatic on-off valve 15 is closed, the pressure on the secondary side of the pump unit 12 rises as the pump 21 is driven, so that it can be confirmed whether or not the pump 21 is driven.

Further, in the above-described example, an example in which the first threshold value stored in the storage unit 43 is set to be non-rewritable has been described, but the present invention is not limited to this. For example, in the second inspection operation that the manufacturer considers necessary for a predetermined period, for example, the second threshold value set as the time of the pump unit 12 from the previous second inspection operation to the next second inspection operation. It may be set as the number of times and stored in advance in the storage unit 43 so as not to be rewritten.

Further, in the above-described example, a configuration in which the deadline operation is performed during the second inspection operation is shown, but the present invention is not limited to this. For example, as shown in FIG. 5, a flow rate detector 61 capable of detecting the flow rate may be provided in the branch pipe (drainage pipe) 15a to detect the flow rate of the branch pipe 15a. With such a configuration, the flow rate can be detected by the flow rate detector 61, and the automatic on-off valve 15 can be opened and closed so as to reach a predetermined flow rate, the head at a predetermined flow rate, and the motor 22 at a predetermined flow rate. The voltage and current supplied to can be detected.

Further, in the above-described example, the third threshold value is the deadline lift during the cut-off operation when the pump unit 12 is normal, the voltage and current supplied to the motor 22 during the cut-off operation, the rated lift during the rated load operation, and The voltage and current supplied to the motor 22 during rated load operation are not limited to this. That is, the third threshold value is not limited to the deadline operation and the rated load operation. For example, the third threshold value may be the lift when the pump unit 12 is operated at a predetermined flow rate under normal conditions, and the voltage and current supplied to the motor 22 when the pump unit 12 is operated at a predetermined flow rate.

Further, in the above-described example, the pump unit 12 is determined to be normal or not based on the third threshold value, but a fourth threshold value different from the third threshold value may be further provided. In such a configuration, for example, the third threshold value is set to a value detected when the pump unit 12 is abnormal, and the fourth threshold value continues the inspection operation but in the future. A value that may become abnormal, in other words, a value that is closer to a value that is closer to the normal value than the operating condition of the pump unit than the third threshold value, and is set to a value smaller than the third threshold value with respect to the current, for example. Then, when the detected detected value satisfies the third threshold value, the control unit 41 determines that the pump unit 12 is not normal and abnormal, and stops the pump unit 12. Further, when the detected detected value does not satisfy the fourth threshold value or satisfies the fourth threshold value and does not satisfy the third threshold value, the control unit 41 continues the inspection operation, and the result of the inspection operation and the like are displayed. The status of the inspection operation may be transmitted to the external terminal 90. Further, when the fourth threshold value is satisfied, information indicating that the fourth threshold value has been exceeded and a warning may be displayed and transmitted to the notification unit 44 and the external terminal 90. For example, the pressure of the pressure detector 33 gradually increases when the detection unit or the primary side piping of the detection unit is clogged by foreign matter such as sand, or when water leaks from the secondary side piping of the pump unit 12. The pressure drops below a predetermined pressure, and there is a risk of sending a start signal for the pump unit 12 to the control panel 18. For example, the water flow detector 314 may detect the water flow when water is leaking from the piping on the secondary side of the pump unit 12 and send a start signal of the pump unit 12 to the control panel 18. By providing the fourth threshold value, it is possible to warn the user and the administrator before an abnormality occurs in the pump unit 12 while continuing the inspection operation.

That is, the present invention is not limited to the above-described embodiment, and can be variously modified at the implementation stage without departing from the gist thereof. In addition, each embodiment may be carried out in combination as appropriate, in which case the combined effect can be obtained. Further, the above-described embodiment includes various inventions, and various inventions can be extracted by a combination selected from a plurality of disclosed constituent requirements. For example, even if some constituent requirements are deleted from all the constituent requirements shown in the embodiment, if the problem can be solved and the effect is obtained, the configuration in which the constituent requirements are deleted can be extracted as an invention.
