Description

  The present invention relates to a pump facility, and more particularly, to a pump facility that performs appropriate operation management and preventive maintenance of the pump facility in accordance with the operation state of the pump facility for flood control.

  The operation of the pump in the conventional pump equipment is performed automatically by operating the related equipment by the pump-linked operation of the operation control panel provided in the electric room of the pump equipment. The panel of the operation control panel has the equipment configuration that displays the status of the pump and motor (electric motor), etc., and issues a start or stop failure, and manages the operation state at the start or stop. Is doing. In addition, the electrical room of the pump facility can make the current operating state visible with an ammeter provided on the operation control panel after the start or stop is completed, and the failure of related equipment is detected by a protection circuit that detects the failure. It is designed to receive a signal, turn on the alarm or failure lamp, and perform repairs and emergency responses.

  In addition, in the pump facility where the operation room is provided separately from the electrical room where the power distribution board is installed, the signal processing function such as a server for transmitting / receiving various signals to / from the operation room, the CRT, etc. A monitoring operation unit having an operation and monitoring function including a display device is provided, and a current value, a bearing temperature, a vibration value, and the like are displayed on the screen of the monitoring operation unit to check the state of the device. In addition, the monitoring operation unit has a function of creating a failure history and the like, and is considered to be useful for maintenance management.

  In this way, the current value, bearing temperature, vibration value, etc., which are items monitored in the electrical room, are collectively displayed on the screen of the monitoring operation unit installed in the operation room, enabling unified management. is there. Also, the monitoring operation unit is often a facility that displays current values, vibration values, etc. in real-time as trend management, and displays a list of failure occurrence history, maintenance history, etc. Therefore, it is used as maintenance information. Here, “trend display” refers to accumulating time-series changes of measured values such as current values, bearing temperatures, and vibration values on a screen of the monitoring operation unit at regular time intervals and displaying them in a graph or the like.

  In the conventional pump equipment mentioned above, the power distribution / control panel installed in the electrical room receives the failure signal of the device and immediately stops the target device and turns on the alarm / failure lamp for post maintenance. It is a facility function corresponding to the failure recovery. In addition, an ammeter or the like is installed in the distribution board, and the facility is capable of visual monitoring of the current operation state.

  In addition, starting a pump in a conventional pump facility is generally performed from an operation point of view by an interlocked start that automatically performs a series of device operations until the start is completed in order to reduce the burden on the operator and prevent erroneous operations. is there. In this case, the operator visually confirms the state of each series of related equipment controlled automatically and confirms that the start-up is finally completed. In the power distribution / control panel, when the series of operations for the interlocking start is not working well, the control is performed so that the start-up time is excessive (start-up congestion) and a serious failure is stopped.

  When such a major failure stop occurs, it is necessary to quickly identify which device has failed in which process, restore it, and restart it. However, with conventional pump equipment, it is difficult to tell where a major failure has occurred, and it takes time to identify the failure location, recovery and restart are delayed, and in the worst case flood damage (for flood control pumps) Case).

  As described above, the electrical equipment in the conventional pump equipment mainly has a post-maintenance function that detects and reports faults and repairs faulty equipment. The pump equipment used for this purpose was not a good management. Also, in maintenance management, preventive maintenance management is performed through timely maintenance that performs periodic management operation, inspection, and repair, but not necessarily including economics such as setting the period and setting the scope of inspection and repair. It was not an efficient preventive maintenance management.

  For example, the HMI device of the monitoring and control device of Patent Document 1 has been proposed as one that addresses the problem of occurrence of a failure in the pump facility and the problem of specifying the failure location. In this device, a prediction is made from the display of symbol marks indicating the state of each device on the driving support screen and the recording of past history. Moreover, in the plant monitoring apparatus of the cited reference 2, the transparent display is dynamically performed while presenting a lot of information to the operator. Further, in the operation support system for a water treatment plant disclosed in Patent Document 3, when a situation in which the water treatment plant cannot be operated is predicted, an alarm output for notifying the occurrence of the situation is performed.

  However, in the cited reference 1 described above, the cause identification / recovery in the start-up congestion failure is merely a probabilistic prediction based on reproducibility, and is not a judgment based on the current operating state, but a highly reliable management / recovery. It was not conservation. Similarly, Cited Document 2 is not a judgment based on the current operation state, and cannot be said to be highly reliable management / maintenance. In Cited Document 3, the management is merely performed according to the prediction result, and it is not a judgment from the current operation state, and it cannot be said that the management / maintenance is highly reliable. Furthermore, the cited documents 1 to 3 did not describe maintenance related to the start-up of equipment and preventive maintenance in maintenance management, which are likely to cause equipment failures.

  The present invention has been made in view of the above-described problems, and is configured with a support function for performing appropriate management and maintenance of the pump equipment from the current operating state, so that the pump equipment having higher reliability and higher maintainability. The purpose is to provide.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Hereinafter, the pump equipment 10 used in the present embodiment will be described mainly with respect to the operation of the pump equipment at the start, taking the pump equipment for flood control as an example, but the present invention is limited to the operation of the pump equipment at the start. Instead, it may be applied when the pump equipment is stopped. In addition, this invention is not limited to the following embodiment.

  First, the whole structure of the pump equipment 10 according to the embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic configuration diagram illustrating a pump facility 10 according to an embodiment of the present invention. As shown in FIG. 1, a pump facility 10 according to an embodiment of the present invention includes an operation chamber 100, an electric chamber 200 electrically connected to the operation chamber 100, and a pump electrically connected to the electric chamber 200. And a driving machine room 300. The operation room 100 includes a main pump 301 to be described later, a drive unit 302 including an auxiliary equipment 303 for driving the main pump 301, and an operation support screen for managing and monitoring the operating state of the main pump 301, the drive machine 302, and the auxiliary equipment 303. The operation flow display unit for displaying the operation flow of the main pump 301, the drive unit 302, and the auxiliary equipment 304 on the operation support screen unit 101, and the operation status of the main pump 301, the drive unit 302, and the auxiliary equipment 303. In addition, the operation state display unit for displaying the operation state of the main pump, the drive unit, and the auxiliary equipment on the operation flow display unit, and the operation time of each device of the pump / drive unit room 300 recognized by the operation state determination unit And a control unit that sends and receives signals to the electric room 200 and the pump / driving machine room 300 of the pump facility 10 and issues an operation stop command. It provided with a bus 102. The electric room 200 includes a power distribution / operation control panel 201 that is controlled by the server 102 and controls the pump / driving machine room 300. The pump / motor room 300 includes a main pump 301, a drive unit 302 for driving the main pump, an auxiliary equipment 303, a drive machine 302, and a machine side operation panel 305 for starting / stopping the auxiliary equipment 303 manually or automatically. Prepare.

  In general, a failure of the pump facility 10 is likely to occur at the time of starting. In particular, there are cases where the auxiliary equipment 303 in the pump equipment 10 at the time of start-up has many faults and cannot be started. Therefore, the pump facility 10 according to the embodiment of the present invention displays the operation state of the pump facility together with the operation flow display unit and the operation flow display unit of the pump facility 10 on the operation support screen unit 101 by lighting, blinking, and the like. By having the section, the current start progress status, that is, the operation status of the pump equipment 10 can be determined at a glance. As a result, when an abnormality (failure) occurs at the start of the pump facility 10 and the operation of the pump facility 10 is stopped due to a serious failure due to start-up congestion, in which state a series of interlocking operations are stopped, that is, It is possible to appropriately determine in which state the abnormality is, and it is possible to quickly and surely recover, and it is possible to construct a highly reliable pump facility. Here, “traffic jam” means that a predetermined operation does not occur (does not complete) within a certain time.

  The pump facility 10 according to the embodiment of the present invention not only displays the operation state of the main pump 301, the drive unit 302, and the auxiliary facility 303 on the operation support screen unit 101 as the operation state grasping unit, By providing a timer unit that displays the operating time of the machine 302 and the auxiliary equipment 303 as an operating state grasping unit, an abnormal location of the pump equipment 10 can be specified more accurately. Here, the operation time represents the time required for the operation of each auxiliary machine to be interlocked when the interlock operation command is input from the machine-side operation panel or the operation room. For example, in the case of a lubricating oil flow relay (reference numeral 413) in FIG. 2, which will be described later, the count-up is started after the operation command of the main pump, the oil flow is generated after the reduction gear lubricating oil pump is started and operated, and the piping of the system, etc. The value at which the count-up is completed when the flow relay installed in the station detects the oil flow, that is, the time required to complete the operation of the related equipment after the main pump operation command is given. The timer part.

  The pump facility 10 according to the embodiment of the present invention provides, for example, an operation from the start of the water supply pump to the water supply flow relay by providing the operation support screen unit 101 with the timer unit that displays the operation time as the operation state grasping unit. If the time is long or short, leakage from the water supply pipe, clogging of the water supply pump or insufficient water absorption, abnormalities in the flow relay, etc. are expected, and it becomes possible to investigate and restore the equipment whose location is specified.

  In particular, in pump facilities that are operating fully automatically at unmanned aerial vehicles, after a failure signal due to start-up congestion is transmitted to a distant location, the operator goes to the aircraft to perform failure recovery. Since the operation status of 10 is not confirmed, it is difficult to identify the cause of failure of the pump equipment. Therefore, according to the above-described configuration of the pump facility 10 according to the embodiment of the present invention, it can be easily understood to which stage the start operation has progressed, and the abnormality target can be quickly identified and restored.

  The pump facility 10 according to the embodiment of the present invention displays the operation flow on the operation support screen unit 101, manages the operation of the main pump 301 driven by the driving device 302, operates the vacuum pump used as the auxiliary device 303, By providing a timer unit and a storage unit as an operation state grasping unit that manages the time until the pump 301 is full or the operation of the flow relay (running water confirmation) or the operation is completed, the auxiliary equipment 303 It is possible to manage performance deterioration (for example, decrease in discharge amount) and pipe deterioration (for example, leakage, clogging, etc.) and make improvements and repairs before failure occurs. In this way, by performing preventive maintenance at appropriate timing and location, it is possible to construct and maintain the highly reliable pump facility 10. In addition, although the operation state grasping | ascertainment part demonstrated to the timer part which displays the operation time of each pump equipment as an example, the operation state grasping part is not limited to a timer part, if it can manage the operation state of pump equipment Anything may be used.

  Next, in the pump facility 10 according to the embodiment of the present invention, the operation state displayed on the operation support screen unit 101 of the operation room 100 and the operation state grasping unit displayed together with the operation flow will be described with reference to FIGS. I will explain.

  FIG. 2 is a diagram illustrating an example in which a timer unit is used as the operation state displayed on the operation flow and the operation flow displayed on the operation support screen unit 101 of the pump facility 10 according to the embodiment of the present invention. .

  As shown in FIG. 2, first, a pump operation command (interlocking) 400 for the pump facility 10 is issued in the operation room 100 or the machine-side operation panel 305. By this pump operation command (interlocking) 400, the main pump 301, the drive unit 302, and the auxiliary equipment 303 configured in the pump and drive unit chamber 300 perform a start operation in conjunction with each other. Here, the following pump equipment 10 uses a horizontal shaft pump for the main pump 301, uses an electric motor for the driving machine 302, and uses an intake valve, a vacuum pump, a full water detector, a speed reducer for the auxiliary equipment 303. This is an example using a lubricating oil pump and a water supply (cooling / sealing) valve. The machine side operation panel 305 is a panel for starting and stopping the driving machine 302 and the auxiliary equipment 303 manually or automatically on the machine side.

  Here, a series of operations will be described with reference to FIG. When an instruction for interlocking operation of the main pump is issued, the intake valve connected to the horizontal axis pump is then opened (reference numeral 401). At this time, the timer unit 402 displays on the driving support screen 101 a time required from the driving command until the intake valve is opened, for example, 15.00 sec.

  Next, the vacuum pump is started (reference numeral 403). The vacuum pump is driven by an electric motor connected to the vacuum pump, and when the vacuum pump starts, the air in the casing of the horizontal shaft pump is sucked through the intake valve, and the water in the suction water tank is introduced into the casing. The At this time, the timer unit 404 displays the operation time of the vacuum pump, for example, 17.00 sec on the operation support screen 101.

  Next, a full water detector that detects the full water in the casing of the horizontal axis pump operates (reference numeral 405). At this time, the timer unit 406 displays the operation time of the full water detector, for example, 318.30 sec on the operation support screen 101.

  Further, after the operation command (interlocking) 400 of the horizontal axis pump is issued, the speed reducer lubricating oil pump is started in parallel with the intake valve opening control (reference numeral 411). The speed reducer lubricating oil pump includes a speed reducer and lubricating oil, and further includes a lubricating oil supply unit. Lubricating oil circulates between the reduction gear and the lubricating oil supply unit via a pump of the reduction gear lubricating oil pump. The speed reducer includes a plurality of gears and bearings of these gears, and the gears and the bearings are lubricated by the lubricating oil supplied from the lubricating oil supply unit. At this time, the timer unit 412 displays on the driving assistance screen 101 the time required for starting the reduction gear lubricant pump after the start command for the main pump is issued, for example, 1.30 sec.

  Next, the flow relay installed in the system piping is mechanically operated by operation of the reduction gear lubricant pump (reference numeral 413). At this time, the timer unit 414 displays the time required for the flow relay operation of the reduction gear lubricant pump, for example, 6.50 sec, on the operation support screen 101 after the start command for the main pump is issued.

  Further, after the pump operation command (interlocking) 400 is issued, the water supply (cooling / sealing) valve is opened (reference numeral 421) in parallel with the intake valve opening control and the reduction gear lubricating oil pump start-up. The water supply valve is connected to a water supply pump through a water supply pipe. At this time, the timer unit 422 displays on the driving support screen 101 the time required until the water supply valve is opened, for example, 15.00 sec, as with the other devices described above.

  Next, the water supply pump is started (reference numeral 423). The feed water pump is connected to a cooler such as a drive machine, a shaft seal portion of the main pump, and the like through a feed water pipe and a feed water valve. At this time, the timer unit 424 displays the time when the start of the water supply pump is completed, for example, 17.00 sec on the driving support screen 101.

  Next, the flow relay installed in the system piping is mechanically operated by operation of the feed water pump (reference numeral 435). At this time, the timer unit 436 displays a time required for the flow relay operation of the water supply pump, for example, 22.00 sec on the driving support screen 101.

  In addition, after the pump operation command (interlocking) 400 is issued, the pump start congestion circuit is turned on in parallel with the control of the intake valve, reduction gear lubricant pump, water supply (cooling / sealing) valve, etc. It is set (reference numeral 441). The pump start-up congestion circuit is used to check for start-up failures (start-up not reached) due to abnormalities in auxiliary equipment during the start-up of the pump equipment. The start-up of the main pump is completed within an arbitrary set time after the operation command. If not, it is determined that there is an abnormality, a warning is issued, and the failure lamp is turned on. At this time, the timer unit 444 counts down from a preset time, for example, 600.00 sec, and ends the counting after the start of the main pump is completed. If the count value becomes 0 before the start of the main pump is completed, it is regarded as abnormal and a serious failure is stopped. In this way, by checking the remaining time until a start-up traffic jam (major failure) occurs, it is possible to identify the abnormal part in combination with the above-mentioned timer values and to recover before the major failure occurs. Thus, the reliability can be further improved.

  Next, when the operation of the full water detector (reference numeral 405), the flow relay operation (reference numeral 413), and the flow relay operation (reference numeral 435) are operated and all these operations are confirmed (the AND shown in FIG. 2). ), The process proceeds to “T” of the next confirmation timer unit 452. The confirmation timer unit 452 is for delaying a fixed time after the AND condition is established and proceeding to the next operation, and is generally set to about 1 to 10 seconds.

  By combining this timer display unit and the operation flow display unit that displays the current operation state, starting congestion occurs from the tendency at the time of operation and start of the conventional pump equipment and the arrival position in the current operation state It is also possible to recover the abnormal part before. In this way, by avoiding the occurrence of start-up congestion itself, it is possible to prevent start-up delays such as water supply pumps that function as auxiliary equipment, prevent inundation damage, and provide highly reliable pump equipment. .

  Next, the main circuit breaker of the electric motor used as a drive machine is turned on (reference numeral 461). When the electric motor main circuit breaker is turned on, the pump shaft is rotated by the electric motor, and the water in the suction water tank is pumped up and discharged to the discharge water tank through the discharge valve. At this time, the timer unit 462 displays on the operation support screen 101 the operation time required for the motor main circuit breaker to be turned on, for example, 324.00 sec, after the start command for the main pump is issued.

  Next, a protection circuit is formed (reference numeral 481). This protection circuit formation means that a protection circuit (failure detection / measurement item) that functions only after the main pump is started is utilized in control. Applicable measurement / detection items include abnormal drop in water absorption level of the pump and lubrication oil breakage. Before the main pump starts moving (before auxiliary equipment operates), it is not strange. It is a detection item. For example, the lubricant flow is a natural state when the lubricant pump is not operating.

  When the motor main circuit breaker is turned on, the intake valve connected to the horizontal axis pump is closed in parallel with the formation of the protection circuit (reference numeral 471). The intake valve is controlled to close when the motor main circuit breaker is turned on. At this time, the timer unit 472 displays on the driving support screen 101 the operation time required until the intake valve is closed, for example, 339.00 sec.

  Next, the vacuum pump is stopped (reference numeral 472). The vacuum pump stops operating when the intake valve is closed. As a result, the operation of filling the casing is completed.

  When the motor main circuit breaker is turned on, the discharge valve starts to open in parallel with the formation of the protection circuit and the intake valve closing control (reference numeral 463). At this time, the timer unit 464 displays the time when the opening operation of the discharge valve is started, for example, 325.00 sec, on the driving support screen 101.

  Next, the discharge valve is opened (reference numeral 465). When the discharge valve is opened, the water in the suction water tank is pumped by the horizontal axis pump and discharged into the discharge water tank.

  Next, the discharge valve continues to open and reaches the fully open position (reference numeral 467). At this time, the timer unit 468 displays on the driving assistance screen 101 the time when the discharge valve reaches the fully open position, for example, 506.00 sec.

  Next, in response to the fact that the discharge valve is fully opened and the pumping function is manifested, that is, the start of the pump is completed, the pump start congestion circuit that has been counted down is turned off (reference numeral 469). At this time, the timer unit 470 displays on the driving support screen 101 the time when the pump start congestion circuit is turned off, for example, 327.00 sec.

  Next, when the pump start congestion circuit is cut off, the operation state grasping unit indicating that the start of the pump operation is completed is lit or blinks (reference numeral 490).

  As described above, the pump facility 10 according to the embodiment of the present invention displays the operation flow on the operation support screen unit 101, and as the operation management of the main pump 301 driven by the drive unit 302, as the auxiliary facility 303. The operation of the vacuum pump used, the time until the main pump 301 is fully filled, the flow relay (flowing water confirmation) operation, etc. or the time until the operation is completed is displayed as a timer part to control the state, thereby starting failure ( (Congestion) can be prevented in advance or can be quickly recovered, and reliability can be improved. In addition, by managing the trend of the starting state and the timer value, the performance deterioration of the auxiliary equipment 303 (for example, a decrease in discharge amount) and the deterioration of the piping (for example, leakage, clogging, etc.) are managed. It becomes possible to make improvements and repairs before failure occurs. In this way, by performing appropriate preventive maintenance, it is possible to construct and maintain the highly reliable pump facility 10.

  Further, in the pump facility according to the embodiment of the present invention, during the start-up operation, the operation flow and the operation operation time of the main pump, the drive unit, and the auxiliary equipment are displayed on the operation support screen unit to allow the operator to recognize the operation flow. By the single operation that is the operation method when abnormality occurs in the power distribution / operation control panel, for example, it is established as knowledge when starting auxiliary equipment individually on the machine side operation panel in the prescribed order, It prevents the operator's mistaken operation in an emergency and improves the reliability of the pump equipment.

  The example shown in FIG. 2 shows an example in the case of a suction and electric motor-driven horizontal shaft mixed flow pump, but it may be a start by pushing in, an engine drive described later, and other pump types, I do not care. In particular, in the case of engine driving, since there are many devices attached to the engine and the failure probability at the time of starting is high, an operation / management support device that displays an operation flow and an operation time is particularly effective.

  The embodiment of the present invention described above relates to the operation flow at the start when the failure occurrence probability is high, but the operation flow and the operation time may be similarly displayed and managed for the control at the time of stop. .

  Each timer unit according to the above-described embodiment of the present invention has been described with respect to an example in which the operation time of each device in the pump facility is displayed, but not only the operation time is displayed but also the past operation time and the current operation time. By displaying the threshold value for alerting and the current operation time, which are displayed in parallel, the trend management of the pump facility 10 can be more reliably performed, and the maintainability can be improved. The past operation time to be written may be a timer value at the time of the previous start, but is preferably an average value of the past several timer values.

  Next, an example in which an engine is used as a driving machine will be described with reference to FIG. FIG. 3 is a diagram illustrating an example in which a timer unit is used as the operation state grasping unit displayed together with the operation flow and operation flow of the pump facility 10 according to the embodiment of the present invention. A detailed description of the operation unit described with reference to FIG. 2 and the timer unit as the operation state grasping unit displayed together with the operation flow will be omitted.

  As shown in FIG. 3, first, in the operation room 100 or the machine-side operation panel 305, a pump operation command (interlocking) 500 for the pump facility 10 is issued. By this pump operation command (interlocking) 500, the main pump 301, the driving machine 302, and the auxiliary equipment 303 that are configured in the pump and driving machine room 300 are operated and controlled in conjunction with each other.

  Next, the vacuum pump is started (reference numeral 503). The vacuum pump is driven by an electric motor connected to the vacuum pump, and when the vacuum pump starts, the air in the casing of the horizontal shaft pump is sucked through the intake valve, and the water in the suction water tank is introduced into the casing. The At this time, the driving state grasping unit that lights or blinks that the driving operation is performed, and the time required to reach the operation are displayed on the driving support screen 101 as the timer unit 504.

  Next, a full water detector for detecting the full water in the casing of the horizontal axis pump operates (reference numeral 505). At this time, the driving state grasping unit that lights or blinks that the driving operation is performed, and the time required to reach the operation are displayed on the driving support screen 101 as the timer unit 506.

  Further, after the operation command (interlocking) 500 for the horizontal axis pump is issued, the speed reducer lubricating oil pump is started in parallel with the intake valve opening control (reference numeral 511). The reduction gear lubricating oil pump includes a reduction gear, a lubricating oil pump, and further includes a lubricating oil supply unit. Lubricating oil circulates between the reduction gear and the lubricating oil supply unit via a pump of the reduction gear lubricating oil pump. The speed reducer includes a plurality of gears and bearings of these gears, and the gears and the bearings are lubricated by the lubricating oil supplied from the lubricating oil supply unit.

As the driving machine 313, an electric motor, a diesel engine, or the like is used. The driving machine 313 includes a cooler 314, and includes a sensor unit 337 provided on the inlet side of the cooler 314 and a sensor unit 338 provided on the outlet side. The water supply pump 359 is connected to a water supply valve 358 that opens and closes the water supply pipe 360, and the water supply pipe 360 is connected to the cooler 314 and the shaft seal 325. By driving the drive unit 313, the pump shaft 323 rotates via the speed reducer 315, and the water in the suction water tank 311 is pumped up by the horizontal shaft pump 310 and discharged into the discharge water tank. Instead of the horizontal shaft pump 310, a vertical shaft pump may be used, and a pump such as a mixed flow pump, an axial flow pump, or a vortex pump may be used as the pump type.

  An intake line (intake pipe) 355 is connected to the casing 321 of the horizontal axis pump 310. The intake line 355 is provided with a full water detector 350 for detecting the full water in the casing 321 and an intake valve (motor valve or electromagnetic valve) 351 for opening and closing the intake line 355. The intake line 355 communicates with the suction side of the vacuum pump 352 via the intake pipe 356. The vacuum pump 352 is connected to an electric motor 353 that drives the vacuum pump 352, and drains (exhales) 354 through a drain pipe 357.

  The example shown in the figure shows a case of a horizontal shaft mixed flow pump driven by suction and electric motor, but it may be a case of starting by pushing in, or it may be an engine drive or another pump type. In particular, in the case of engine driving, since there are many devices attached to the engine and the failure probability at the time of starting is high, an operation / management support device that displays an operation flow and an operation time is particularly effective.

  As shown in FIG. 6, each sensor unit provided in the pump facility 10 according to the embodiment of the present invention uses a discharge valve 312 to measure the temperature of the bearing, for example, the temperature of the bearing of the cooler 314. After closing, the deadline is reached, and the driving machine 313 is stopped. The measurement is continuously performed for about 10 minutes, and the deterioration of the bearing grease is checked by observing how the temperature decreases. In this case, the gradient of the decrease in the bearing temperature is different from the usual. Or, when there is a tendency for the temperature at the time of stoppage (temperature saturated in operation) to increase, it is judged that the grease has deteriorated, and the grease is replaced to make the oil replacement work more appropriate. Is possible. Thus, the pump facility 10 should be continuously operated to some extent before the operation is stopped. Therefore, the temperature of each bearing provided in the pump facility 10 is also saturated and stable. From the stable state, it is possible to estimate the deterioration of the grease by looking at the temperature decrease rate of the bearing due to the air heat radiation after the drive unit 313 is completely stopped. If the grease does not change even if it is replaced, it is judged that there is another abnormality, and it is possible to improve reliability through preventive maintenance by considering precision inspection and bearing replacement.

  In addition, as a conventional management method by measuring the temperature of the bearing, a method of measuring and managing the pump in the start-up or operation state is used, but in parallel operation, for example, parallel operation in a centrifugal pump machine, etc. There are many operation patterns with different operation states, and it is very difficult to manage the trend of the pump conditions in the same operation state. Therefore, as a means for performing comparison in the same state, appropriate trend management can be performed by managing the state at the time of stop and after the stop.

  After shutting down the pump facility operation command, if the deadline is stopped, the discharge valve may start closing, and the pump facility operating state may be measured and stored together with the small water amount, deadline, and complete stoppage. . If configured in this way, it is possible to infer from the measured values of vibration and temperature the influence of misalignment due to the load applied to the bearing by cavitation and the deterioration of the bearing when the amount of water is small. Maintenance management and trend management become possible.

  Next, based on the operation time or temperature change storage unit in the pump facility described above, a graph indicating the operation state of the pump facility shown in FIGS. 7 to 9 is created, and the operation of the pump facility 10 is performed from the created graph. An example of managing the situation will be described.

  FIG. 7 is a graph showing an example of temperature management in pump equipment according to another embodiment of the present invention. In FIG. 7, the horizontal axis indicates the operation year or the number of start times, and the vertical axis indicates the cooler temperature. The temperature management shown in FIG. 7 is not limited to the above-described bearing temperature, but may be the inlet temperature / outlet temperature of the cooling water cooler (cooler). By managing the tendency of the temperature difference between the inlet temperature and the outlet temperature, it becomes possible to announce the cleaning timing of the heat exchange part, which is one of the main maintenance items.

  FIG. 8 is a graph showing an example of measuring the temperature of the bearing after an operation stop command for pump equipment according to another embodiment of the present invention. FIG. 8 shows elapsed time on the horizontal axis and temperature on the vertical axis. As shown in FIG. 8, since the measurement is performed at the time of stopping, the bearing is in a saturated state, and the final control target of the pump is the same for all stop patterns as the discharge amount = 0. Depending on the water level of the final control target (pump operating conditions) at the time of start-up, parallel operation, etc., the final ultimate discharge amount / operating point of the pump will differ, but there will be no variation. Further, FIG. 8 shows the operation state when the pump equipment is stopped, but the operation state at the time of start and operation may be stored together.

  FIG. 9 is a graph showing an example of an operating state of pump equipment according to another embodiment of the present invention. FIG. 9 shows items as auxiliary equipment on the horizontal axis, for example, intake valve opening, vacuum pump start and full water detector operation, and vertical axis shows the operation time of intake valve open, vacuum pump start and full water detector operation, respectively. Indicates. FIG. 9 shows a threshold value set by a trial operation of the pump facility or a preset state according to the time of operation of the intake valve opening, the vacuum pump start and the full water detector operation in the pump facility, and the intake air in the pump facility. Depending on the operation time of valve opening, vacuum pump start and full water detector operation, intake valve open, abnormal value indicating vacuum pump start and full water detector operation abnormal state (failure), intake valve open in actual pump equipment The actual value which shows the state which the vacuum pump start and the full water detector operation | movement operated is each shown. The abnormal value may refer to the operation time of the past operation of the pump equipment, and in this case, it is preferable to display the date and time of operation. As described above, the operation time in the pump facility is graphed according to the auxiliary equipment, and the threshold value, the abnormal value, and the actual measurement value are displayed and compared, thereby making it easy to manage the trend of the pump facility. . In FIG. 9, each item of the auxiliary equipment is shown on the horizontal axis. You can manage the trend by graphing. By setting the horizontal axis to the time series such as the operation date and time and the number of start times, the pump equipment can easily manage the tendency of the aging deterioration (deterioration due to the number of start times) of the auxiliary pump and the like.

  Although the example of a display of the driving assistance screen part was shown in FIGS. 7-9, it is good also as management and a display by a table | surface for the purpose of calculation of an average value. Or you may comprise so that both a graph and a table | surface can be displayed.
