Description

Fixation sensing functional pump, fixation sensing system for pump and high safety fire pump system comprising the same and operating method thereof

The present invention relates to a functional pump for detecting stickiness, a pump sticking detection system including the functional pump for detecting sticking, and a high-safety fire pump system including the sticking monitoring system, and more particularly, to detect and cope with sticking in the pump It is about a fire pump system.

In the firefighting system for fire suppression provided in a building, in the case of an old building, fire suppression is not performed due to poor management of a fire pump for supplying fire extinguishing water to a sprinkler, so disasters occur continuously.

The main reason for the failure of the fire pump is that the impeller, a key part of the fire pump, is made of cheap cast iron and is highly likely to corrode. Since it is filled with water so that it can be operated, if left unattended for a long time, corrosion of materials such as cast iron was inevitable. When corrosion and sticking occur inside the pump, the impeller does not rotate properly, and the function of the pump itself deteriorates, making it difficult to supply water to the sprinkler.

Accordingly, domestic and foreign countries are considering regulations to prevent the use of corrosive materials for fire pump parts including impellers, and parts made of corrosion-resistant stainless steel will be recommended. However, this is limited to only the impeller and shaft connected to the shaft of the motor for driving the pump and rotating in the pump, not all parts of the fire pump. It is expected that, even if the internal impeller and pump shaft are made of corrosion-resistant materials, if other parts such as the pump casing are made of corrosive materials, there is still a possibility of corrosion and sticking, so the problem still seems difficult to solve.

Korean Patent Registration No. 10-0955704 "Capacitive Fire Pump System" (hereinafter referred to as the prior art) to solve this problem is to perform automatic test operation of the pump regularly through the control of the controller as shown in FIG. 1 to fire the fire pump It was intended to prevent the sticking problem of the impeller. The prior art is a method of dumping the water discharged during automatic operation of the fire pump into a drain through a branched discharge pipe, and the fire pump must be driven frequently enough to prevent the impeller from sticking. There was a problem that water was wasted.

In order to reduce the amount of discharged water, an inverter that reduces the number of rotations of the pump can be applied, but the inverter to drive the motor for a large-capacity pump is relatively expensive, which increases the overall price of the fire pump. Since there are few places to be applied and an induction motor of a constant speed drive method is used, the prior art has been difficult to actually apply.

Hereinafter, the technical idea of the present invention will be described in more detail using the accompanying drawings. Prior to this, the terms or words used in this specification and claims should not be construed as being limited to the usual or dictionary meaning, and the inventor appropriately uses the concept of the term in order to explain his/her invention in the best way. It should be interpreted as a meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.

Hereinafter, the configuration and characteristics of the functional pump 10 for detecting adhesion of the present invention will be described with reference to FIG. 2 .

The sticking-detecting functional pump 10 of the present invention is a pump capable of detecting internal corrosion and sticking itself, and includes a suction port and a discharge port and has a space formed therein to apply force to an impeller or a fluid. It may include a casing 11 and a sticking detection unit 12 provided in an inner space of the pump casing 11 .

At this time, the sticking detection unit 12 may provide information on the state of the fluid inside the pump casing 11 . The sticking detection unit 12 may be a sensor contacting the inner surface of the pump casing 11 . The sticking detecting unit 12 may include an electrical resistance measuring unit 12a and a turbidity measuring unit 12b.

When corrosion occurs inside the pump casing 11, corroded iron particles are mixed with the fluid and float, and the electrical resistance value of the fluid may decrease. That is, when the electrical resistance value measured by the electrical resistance measuring means 12a is below a certain value, it can be determined that corrosion has occurred inside the pump casing 11 . The electrical resistance measuring means 12a may be an electrical resistance measuring instrument.

In addition, the electrical resistance measuring means 12a may be attached to the inner surface of the pump casing 11, or is located outside the pump casing 11, and receives the fluid inside the pump casing 11 at regular time intervals. Thus, the electrical resistance can be sensed.

When corrosion occurs inside the pump casing 11, corroded iron particles are mixed with the fluid to float, and the turbidity of the fluid may increase. That is, when the turbidity measured by the turbidity measuring means 12b is above a certain value, it can be determined that corrosion has occurred inside the pump casing 11 . The turbidity measuring unit 12b may include a light emitting unit and a light receiving unit attached to the inner surface of the pump casing 11 . More specifically, in a state where the light emitting unit emits light at a constant intensity and the light receiving unit receives and detects light from the light emitting unit, when corrosion occurs inside the pump casing 11 and the turbidity of the fluid increases, a certain amount of light received by the light receiving unit is blocked. and turbidity can be detected.

At this time, for the accuracy of measurement, the light emitting part and the light receiving part may be disposed to face each other, and the light emitting part and the light receiving part are disposed in a position where there is no interference of structures of the sticking detection functional pump 10 such as an impeller therebetween it is desirable

The possibility of corrosion can be calculated based on electrical resistance, which is advantageous for detecting corrosion, and the possibility of sticking can be calculated through turbidity measurement, which is advantageous for detecting sticking.

Due to this configuration, the manager can more accurately recognize the state of the pump.

In addition, pump abnormality warning information may be generated based on the possibility of corrosion and the possibility of sticking.

The pump failure warning information may be calculated by assigning weights to the possibility of corrosion and the possibility of sticking.

A weight assigned to the possibility of sticking may be higher than a weight assigned to the possibility of corrosion. As an example, the pump failure warning information is obtained by multiplying the possibility of corrosion by a weight k1 and by multiplying the possibility of sticking by a weight k2, and k2 > k1.

As another example, a pump failure warning level in the case where the possibility of corrosion is low and the possibility of sticking is high may be calculated higher than the warning level of the pump failure in the case where the possibility of corrosion is high and the possibility of sticking is low.

Due to this configuration, the manager can more intuitively recognize the state of the pump.

In addition, errors in turbidity measurement and electrical resistance measurement can be estimated based on the possibility of sticking and corrosion.

Corrosion tends to occur first compared to sticking of the pump, so if the electrical resistance is very high even though the turbidity is very high, it can be determined that there is an error in the electrical resistance measurement or in the turbidity measurement.

The controller compares the turbidity measurement result and the electrical resistance measurement result, stores the measurement result and/or relative comparison value, and determines whether or not the measurement error is based on the stored measurement history and/or comparison value and the currently measured turbidity and electrical resistance. can judge

The measurement error and/or pump abnormality warning information may be divided into a plurality of steps to provide the user with the state of the pump and the sensor unit.

Due to this configuration, there is an effect of improving reliability of pump state information and reducing unnecessary management work due to measurement errors.

Hereinafter, the configuration and characteristics of the pump sticking detection system 100 of the present invention will be described with reference to FIG. 3 .

The pump sticking detection system 100 may include the sticking detection functional pump 10 described above. In addition, the pump sticking detection system 100 receives the internal fluid state information of the sticking detection functional pump 10 from the sticking detecting unit 12, and the control unit 20 determines whether or not the inside of the pump casing 11 is corroded or stuck. ) may be included. The following paragraph describes an algorithm in which the control unit 20 makes a final decision by integrating information received from the sticking detecting unit 12 .

The control unit 20 may receive the turbidity and electrical resistance values of the fluid from the sticking detection unit 12. Even if the turbidity of the fluid exceeds a certain standard or the electrical resistance value is below a certain standard, an erroneous detection occurs. In order to exclude the case, it can be finally determined that corrosion has occurred inside the sticking detection functional pump 10 when the above-described state lasts for a predetermined time or more.

In addition, the control unit 20 may store in the memory data for determining the presence or absence of corrosion and adhesion of the inside of the pump casing 11 . The information stored in the memory may include a status of information received from the sticking detecting unit 12 and a status of determination of sticking. In addition, whether the determination of the control unit 20 is true or false may be received from a user and stored in a memory.

The control unit 20 performs deep learning based on the above-described information (information received from the sticking detection unit 12, determination of corrosion or sticking inside the pump casing 11, and whether or not the determination information is true or false), Error cases can be learned, and turbidity status and electrical resistance status can be learned when actual corrosion and sticking are detected. Accordingly, even when the turbidity value and the electrical resistance value are measured abnormally due to a simple device failure of the sticking detecting unit 12, it is possible to discriminate and determine whether or not the sticking is present.

In addition, the control unit 20 may perform the above-described deep learning to adjust a reference value for determining whether or not there is corrosion or sticking inside the pump casing 11 . Even if corrosion does not occur depending on the season or the location where the pump is placed, it may affect the turbidity or electrical resistance of the internal fluid, but the pump sticking detection system 100 of the present invention does not directly receive information about this from the user. It is possible to increase the accuracy of the measurement by automatically adjusting the reference value without

Below, with reference to FIG. 4, the teaching of this invention is demonstrated.

The high-safety fire pump system 1000 of the present invention includes the pump sticking detection system 100 including the above-described sticking detection functional pump 10, a water tank 200 in which fluid is stored, and a sticking detecting functional pump 10 It may include a spraying unit 300 for receiving fluid from and spraying it to the outside. In addition, the bridge may include a pipe part 400 and a valve part 500 coupled to the pipe part 400 to control opening and closing of the pipe part 400. The pipe part 400 may include a circulation pipe 410 and an injection pipe 420, and when the circulation pipe 410 is opened, it connects the sticking detecting functional pump 10 and the water tank 200 so that the fluid The sticking detection function pump 10 and the water tank 200 may be circulated. As shown in FIG. 4 , the circulation pipe 410 includes a pipe through which the fluid moves from the functional pump 10 to the water tank 200 and a pipe through which the fluid moves from the water tank 200 to the functional pump 10 detecting stickiness. Two or more may be disposed, or one pipe capable of moving fluid in both directions may be disposed. The spray pipe 420 may connect the functional pump 10 for detecting stickiness and the injection unit 300 so that the fluid discharged from the functional pump 10 for detecting stickiness may be sprayed to the outside.

In a state in which the control unit 20 does not determine corrosion and sticking inside the pump casing 11, that is, in normal times, the control unit 20 controls the valve unit 500 so that the injection pipe 420 is opened and the circulation pipe 410 ) is preferably closed. This is to prepare the internal fluid of the sticking detection functional pump 10 to be injected to the outside when the fluid needs to be injected and delivered to the outside of the bridge, such as in a fire situation.

In addition, when the control unit 20 determines corrosion and sticking inside the pump casing 11, the control unit 20 controls the valve unit 500 so that the injection pipe 420 is closed and the circulation pipe 410 is opened. By doing so, it is possible to prevent foreign substances generated due to corrosion from sticking to the impeller inside the seismic functional pump 10 while the fluid circulates inside the seismic functional pump 10 . At this time, since the circulated fluid is recycled, waste of fluid due to additional operation of the sticking detecting functional pump 10 can be reduced.

At this time, it is preferable that the fluid discharged from the functional pump 10 for detecting stickiness is sucked into the suction port of the functional pump 10 for detecting stickiness via the water tank 200 . Since the sticking detection functional pump 10 requires a large force when used for firefighting, the discharge flow rate is very high, and when the discharge flow rate is not reduced and sucked into the suction port, the load applied to the suction port increases, so the pump casing 11 life expectancy is likely to be shortened. Therefore, by allowing the fluid to be sucked into the seismic functional pump 10 via the water tank 200, the load of the inlet can be reduced, and the seismic functional pump 10 can be used stably for a longer period of time. Furthermore, by including a filtering device inside the water tank 200, foreign substances floating in the fluid due to corrosion can be filtered out, and the fluid can be used longer without replacement.

In addition, the high safety fire pump system 1000 may include a pressure gauge 600 for transmitting information to the control unit 20, a flowmeter 700, a speedometer 800, and a water level sensor 900. The pressure gauge 600 is coupled to the injection pipe 420 to measure the hydraulic pressure inside the injection pipe 420, and the flow meter 700 is coupled to the circulation pipe 410 to measure the flow rate inside the circulation pipe 410, The speedometer 800 is coupled to the outlet of the pump casing 11 to measure the flow rate of the outlet of the sticking detection functional pump 10 . In addition, the water level sensor 900 may be attached to the inside of the water tank 200 to detect the water level inside the water tank 200 .

The pressure gauge 600 and the flowmeter 700 may send information to the control unit 20 to feedback whether the injection pipe 420 and the circulation pipe 410 are open, and the hydraulic pressure of the injected fluid and the flow rate of the circulating fluid The control unit 20 can effectively adjust. Also, the speedometer 800 may allow the control unit 20 to determine whether the sticking detecting functional pump 10 is normally operating. In addition, the water level sensor 900 transmits the amount of fluid inside the water tank 200 to the control unit 20 in real time, thereby preventing a situation in which the water tank 200 overflows when the fluid is injected into the water tank 200 at a certain height or more. When the fluid is injected into the tank 200 at a certain height, the controller 20 opens the tank 200 so that the fluid is discharged from the tank 200 at a constant flow rate without a separate pump and has a sticking detection function. It can be circulated to the inside of the pump 10.

The valve unit 500 may be respectively disposed on the circulation pipe 410 and the injection pipe 420 . The valve unit 500 may be a valve disposed in either the circulation pipe 410 or the injection pipe 420 . For example, as shown in FIG. 4 , when the valve is disposed only in the injection pipe 420, when the valve of the injection pipe 420 is opened, the injection pipe 420 is opened and the fluid of the sticking detection functional pump 10 is discharged. It flows through the injection pipe 420, and naturally, the fluid may not flow through the circulation pipe 410. Conversely, when the valve of the injection pipe 420 is closed, the fluid of the sticking detection functional pump 10 flows into the circulation pipe 410, so the circulation pipe 410 may be opened.

In addition, the valves of the valve unit 500 may be disposed in the injection pipe 420 and the circulation pipe 410, respectively. Accordingly, an error occurs in one of the two valves, and the fluid flows to both the injection pipe 420 and the circulation pipe 410, or neither flows to the injection pipe 420 or the circulation pipe 410. can prevent

In addition, the valve of the valve unit 500 may be disposed at the lower end of the water tank 200 . This means that when the fluid is injected into the tank 200 at a certain height when the fluid is circulated between the functional pump 10 and the tank 200 to prevent the functional pump 10 from sticking, the control unit 20 ) is to open the water tank 200 so that the fluid is discharged from the water tank 200 at a constant flow rate without a separate pump and circulated into the sticking detection functional pump 10.

In the following, the object of the present invention will be described with reference to FIGS. 5 to 8 .

As shown in FIG. 5, a process using the high-safety fire pump system 1000 may include an information receiving step, an analysis and determination step, a mode setting step, and an execution step. The information receiving step may be a step in which the control unit 20 receives information from the sticking detecting means. As shown in FIG. 6, the information receiving step includes an electrical resistance receiving step in which the control unit 20 receives the electrical resistance value of the fluid from the electrical resistance measuring device, and the control unit 20 receives the turbidity value of the fluid from the turbidity measuring device. It may include a turbidity receiving step of receiving. The electrical resistance receiving step and the turbidity receiving step may be performed at the same time, and are preferably performed at all times. In addition, when only one of the electrical resistance measuring means 12a and the turbidity measuring means 12b is attached to the inside of the sticking detecting functional pump 10 applied to the high-safety fire pump system 1000, some steps corresponding thereto are omitted. It can be.

The analysis and determination step may be a step in which the control unit 20 analyzes the information received from the sticking detecting means to determine whether or not there is corrosion or sticking inside the pump casing 11 . At this time, based on the turbidity and electrical resistance values of the fluid received from the sticking detection unit 12, the control unit 20 receives a state in which the turbidity of the fluid is higher than or equal to a certain standard or the electrical resistance value is lower than or equal to a certain standard, In order to exclude the case of erroneous detection, it can be finally determined that corrosion has occurred inside the sticking detection functional pump 10 when the above-described state continues for a certain period of time or more.

In addition, the control unit 20 may determine the presence or absence of corrosion and adhesion inside the pump casing 11 based on the reference value adjusted through deep learning performed based on pre-stored data and the turbidity and electrical resistance change status of the fluid. Accordingly, even when the turbidity value and the electrical resistance value are measured abnormally due to a simple device failure of the sticking detection unit 12, the presence or absence of sticking can be determined by discrimination, and corrosion can be determined according to the season or the location where the pump is placed. In the case where the turbidity or electrical resistance of the internal fluid is not affected, the measurement accuracy can be increased by automatically adjusting the reference value without directly receiving information about this from the user.

The mode setting step may be a step in which the control unit 20 sets the mode of the high safety fire pump system 1000 based on the analyzed information. In the mode setting step, when it is determined that corrosion or sticking has occurred in the analysis and determination step, the control unit 20 sets the mode of the high-safety fire pump system 1000 to the sticking detecting functional pump and the fluid along the circulation pipe 410. When the water tank 200 is set to a reciprocating circulation mode, and it is not determined that corrosion or sticking has occurred in the analysis and determination step, the mode of the high-safety fire pump system 1000 is set so that the fluid flows through the injection pipe 420 It is preferable to set the injection mode to be injected.

The performing step may be a step in which the control unit 20 controls the high safety fire pump system based on the mode set in the mode setting step. At this time, when the mode set in the mode setting step is the circulation mode, the execution steps are the injection pipe 420 closing step, the circulation pipe 410 opening step, the circulation flow rate adjustment step, and the water tank 200 as shown in FIG. A water level detection step and a water tank 200 opening step may be included.

In the step of closing the injection pipe 420, the control unit 20 controls the valve unit 500 to close the injection pipe 420 to prevent the fluid from being transferred to the outside, and in the opening step of the circulation pipe 410, the control unit 20 ) may control the valve unit 500 to open the circulation pipe 410 so that the fluid circulates through the sticking detecting functional pump 10 and the water tank 200 . At this time, the step of closing the injection pipe 420 and the step of opening the circulation pipe 410 may be performed at the same time, and the valve of the valve unit 500 controlled by the controller 20 is the circulation pipe 410 or the injection pipe 420. ) can be placed in any one of them. For example, when the valve is disposed only in the injection pipe 420, when the valve of the injection pipe 420 is opened, the injection pipe 420 is opened and the fluid of the sticking detection functional pump 10 flows into the injection pipe 420. And, naturally, the fluid may not flow through the circulation pipe 410. Conversely, when the valve of the injection pipe 420 is closed, the fluid of the sticking detection functional pump 10 flows into the circulation pipe 410, so the circulation pipe 410 may be opened.

In addition, the valves of the valve unit 500 may be disposed in the injection pipe 420 and the circulation pipe 410, respectively. In this case, the closing step of the injection pipe 420 takes precedence over the opening step of the circulation pipe 410. It can be. Accordingly, it is possible to prevent the fluid from leaking out of the high-safety fire pump system 1000, and when an abnormality occurs in one of the two valves, the fluid flows into the injection pipe 420 and the circulation pipe 410. It is possible to prevent a situation in which both flow or no flow in both the injection pipe 420 and the circulation pipe 410.

In the circulation flow rate adjustment step, the control unit 20 compares information of the flow meter 700 connected to the circulation pipe 410 with flow rate information in a predetermined circulation mode, and the flow rate information received from the flow meter 700 is determined in the predetermined circulation mode. If it is larger or smaller than the flow rate information at the time, the flow rate may be adjusted by controlling the sticking detecting functional pump 10 .

In the water level detection step and the water level detection step of the water tank 200, the control unit 20 receives water level information inside the water tank 200 from the water level sensor 900 inside the water tank 200, and the water level in the water tank 200 is a predetermined value. In this case, the circulation pipe 410 connecting the water tank 200 and the inlet of the functional pump 10 for detecting sticking may be opened. This is so that the control unit 20 can open the water tank 200 when fluid is injected into the water tank 200 at a certain height, and the fluid is discharged from the water tank 200 at a constant flow rate without a separate pump, so that the sticking detection functional pump It is intended to be circulated to the inside of (10).

When the mode set in the mode setting step shown in FIG. 8 is the spraying mode, the performing steps may include closing the circulation pipe 410, opening the injection pipe 420, and adjusting the hydraulic pressure.

In the opening step of the injection pipe 420, the control unit 20 controls the valve unit 500 to open the injection pipe 420 to prevent the fluid from being transferred to the outside, and in the closing step of the circulation pipe 410, the control unit 20 ) may control the valve unit 500 to close the circulation pipe 410 so that the fluid circulates through the sticking detecting functional pump 10 and the water tank 200 . At this time, the step of opening the injection pipe 420 and the step of closing the circulation pipe 410 may be performed simultaneously, and the valve of the valve unit 500 controlled by the control unit 20 is the circulation pipe 410 or the injection pipe 420. ) can be placed in any one of them. For example, when the valve is disposed only in the injection pipe 420, when the valve of the injection pipe 420 is opened, the injection pipe 420 is opened and the fluid of the sticking detection functional pump 10 flows into the injection pipe 420. And, naturally, the fluid may not flow through the circulation pipe 410. Conversely, when the valve of the injection pipe 420 is closed, the fluid of the sticking detection functional pump 10 flows into the circulation pipe 410, so the circulation pipe 410 may be opened.

In addition, the valves of the valve unit 500 may be disposed in the injection pipe 420 and the circulation pipe 410, respectively. At this time, the closing step of the circulation pipe 410 takes precedence over the opening step of the injection pipe 420. It can be. Accordingly, it is possible to prevent the fluid to be injected from flowing out into the water tank 200 and pooling therein, and when an abnormality occurs in either one of the two valves, the fluid flows into the injection pipe 420 and the circulation pipe 410. It is possible to prevent a situation in which both flow or no flow in both the injection pipe 420 and the circulation pipe 410.

In the hydraulic pressure adjustment step, the control unit 20 compares the information of the hydraulic system connected to the injection pipe 420 and the hydraulic pressure information in a predetermined injection mode so that the hydraulic pressure inside the injection pipe 420 is kept constant so that the sticking detection functional pump ( 10) and the valve unit 500 can be controlled. Accordingly, the fluid can be injected to the outside with a constant hydraulic pressure, and the load applied to the pipe can be reduced by adjusting the degree of hydraulic pressure applied to the inside of the pipe.
