Description
Technical Field
The present invention relates to a fixation sensing function pump, a pump fixation sensing system including the same, and a high-safety fire pump system including the same, and more particularly, to a fire pump system for handling fixation inside the pump.
Background
In a fire extinguishing system installed in a building, in the case of a worn building, fire cannot be extinguished due to an imperfect management of a fire pump for supplying fire water to a fire shower, and thus a disaster has occurred.
The main cause of such a fire pump failure is that the impeller, which is a core member of the fire pump, is made of inexpensive cast iron, and thus there is a high possibility of corrosion, and the fire pump is driven only in the event of a fire, and the inside of the fire pump and its piping is filled with water so as to be drivable from time to time, and therefore, in the case of long-term storage, corrosion of materials such as cast iron is inevitably generated. When corrosion and fixation occur in the pump, the impeller cannot be rotated well, and the function of the pump itself is lowered, making it difficult to supply water to the fire sprinkler.
Accordingly, in consideration of the above and other circumstances, it is prescribed that a corrosive material cannot be used for a fire pump member including an impeller, and a member made of a corrosion-resistant stainless steel is proposed. However, this is not limited to all parts of the fire pump, but only to the impeller and the shaft connected to the shaft of the pump driving motor and rotated in the pump, and the parts such as the pump casing are still made of cast iron for saving production cost, and even if the inner impeller and the pump shaft are made of corrosion-resistant materials, there is still a possibility of corrosion and fixation if the parts such as the pump casing are made of corrosive materials, and thus it is still difficult to solve the problem.
In order to solve such problems, as shown in fig. 1, in the "electric storage type fire pump system" (hereinafter, referred to as the conventional art) of korean registered patent No. 10-0955704, an automatic test operation of a pump is periodically performed under the control of a controller, thereby preventing the sticking problem of a fire pump impeller. In the conventional technique, in order to prevent the impeller from sticking, the fire pump needs to be driven sufficiently often in order to drain the flow rate discharged during the automatic operation of the fire pump through the branched drain pipe, and a considerable amount of water is wasted each time the fire pump is driven.
In order to reduce the amount of water discharged, an inverter for reducing the number of revolutions of the pump is applicable, but the inverter for driving the motor for a large-capacity pump is relatively expensive, and therefore the price of the entire fire pump increases, and therefore, in actual production, the inverter is hardly applicable to a fire pump, and a constant-speed driving type, that is, an induction motor is used, and therefore, the conventional technology has a problem that it is practically difficult to apply.

Detailed Description
The technical idea of the present invention will be described more specifically with reference to the drawings. The terms and words used in the present specification and claims should not be construed as limited to usual dictionary meanings, but the inventors have interpreted the terms and concepts conforming to the technical ideas of the present invention based on the principle that the concepts of the terms are properly defined in order to explain their own invention in an optimal manner.
The invention relates to a research subject of 50kW vertical multi-stage intelligent fire pump system Development (Development of 50kW vertical multistage smart fire pump system) in the Industry innovation Industry which is developed under the support of Korean industrial trade resource department (Ministry of Trade, industry & Energy (MOTIE) of the Republic of Korea), and is characterized by thank you (subject inherent number: 20011387, contribution ratio: 1/1, ministry of research (strain) dooch, research period: 2020.04.01-2022.12.31)
Next, the structure and features of the fixation sensing function pump 10 of the present invention will be described with reference to fig. 2.
The anchor sensing function pump 10 of the present invention is a pump capable of autonomously sensing corrosion and anchor in the interior, and includes: a pump casing 11 having a structure including a suction port and a discharge port and forming a space therein to apply a force to the impeller or the fluid; and a fixation sensing portion 12 provided in the inner space of the pump case 11.
At this time, the fixation sensing portion 12 provides fluid state information of the inside of the pump case 11. The fixation sensing portion 12 is a sensor that contacts the inner surface of the pump case 11. The fixation sensing portion 12 includes a resistance detection unit 12a and a turbidity detection unit 12b.
In the case where corrosion occurs in the pump casing 11, the corroded iron particles are mixed into the fluid and suspended, and the resistance value of the fluid decreases. That is, when the resistance value detected by the resistance detecting means 12a is equal to or less than a predetermined value, it is determined that corrosion has occurred in the pump casing 11. The resistance detection unit 12a may be a resistance detector.
In addition, the resistance detection unit 12a is attached to the inner surface of the pump case 11 or is located outside the pump case 11, receives the fluid inside the pump case 11 for a prescribed time, and senses the resistance.
In the case where corrosion occurs in the pump casing 11, the corroded iron particles are mixed into the fluid and suspended, and the turbidity of the fluid is increased. That is, when the turbidity detected by the turbidity detecting means 12b is equal to or greater than the predetermined value, it is determined that corrosion has occurred in the pump casing 11. The turbidity detecting unit 12b is constituted by a light emitting portion and a light receiving portion attached to the inner surface of the pump case 11. More specifically, when the turbidity of the fluid increases due to corrosion in the pump case 11 in a state where the light emitting portion emits light with a constant illuminance and the light receiving portion receives light from the light emitting portion and senses the light, the light received by the light receiving portion is blocked by a constant amount, and the turbidity can be sensed.
In this case, for the accuracy of detection, the light emitting section and the light receiving section are disposed so as to face each other, and the light emitting section and the light receiving section are preferably disposed at positions where interference of the structural members of the fixed sensing function pump 10 such as impellers does not exist therebetween.
The corrosion probability is calculated based on the resistance which is advantageous for detecting corrosion, and the sticking probability is calculated by turbidity detection which is advantageous for detecting sticking.
With this configuration, the manager can recognize the state of the pump more precisely.
Further, pump abnormality warning information is generated based on the corrosion possibility and the fixation possibility.
The pump abnormality warning information is calculated by adding a weighted value to the corrosion possibility and the fixation possibility.
The weighting value given to the above-described fixation possibility may be higher than the weighting value given to the above-described corrosion possibility. As an example, the pump abnormality warning information is obtained by multiplying the corrosion probability by a k1 weighting value, multiplying the fixation probability by a k2 weighting value, and adding them together, and k2> k1.
As yet another example, the pump abnormality warning level in the case where the corrosion possibility is low and the fixation possibility is high may be higher than the pump abnormality warning level in the case where the corrosion possibility is high and the fixation possibility is low.
With this configuration, the manager can recognize the state of the pump more intuitively.
In addition, it is inferred that an error occurred in the turbidity detection and the resistance detection based on the fixation possibility and the corrosion possibility.
Since corrosion tends to occur earlier than the fixation of the pump, if the resistance is still very high even though the turbidity is very high, it is judged that there is an error in the resistance detection or an error in the turbidity detection.
The controller compares the turbidity detection result with the resistance detection result, stores the detection result and/or the relative comparison value, and judges whether the detection is wrong or not based on the stored detection history and/or comparison value and the currently detected turbidity and resistance.
The detection error and/or pump abnormality warning information is divided into a plurality of steps to provide the status of the pump and the sensor to the user.
With this configuration, the reliability of the pump state information is improved, and unnecessary management traffic due to detection errors and the like is reduced.
Next, the structure and features of the pump attachment sensing system 100 of the present invention will be described with reference to fig. 3.
The pump fixture sensing system 100 includes the above-described fixture sensing function pump 10. Further, the pump fixation sensing system 100 includes a control section 20 that receives the internal fluid state information of the fixation sensing function pump 10 from the fixation sensing section 12 to determine whether the inside of the pump casing 11 is corroded or fixed. Next, an algorithm for the control unit 20 to integrate the information received from the fixation sensing unit 12 and perform final judgment will be described.
The control unit 20 receives the turbidity and the resistance value of the fluid from the fixation sensing unit 12, and eventually determines that corrosion has occurred in the fixation sensing pump 10 when the turbidity is equal to or greater than a predetermined reference or when the resistance value is equal to or less than a predetermined reference in order to eliminate erroneous detection.
The control unit 20 stores data for determining whether the interior of the pump casing 11 is corroded or not and whether it is fixed or not in a memory. The information stored in the memory includes the current state of the information received from the fixation sensing unit 12 and the current state of the fixation judgment generated thereby. Additionally, the authenticity of the judgment by the control unit 20 is received from the user and stored in the memory.
The control unit 20 performs deep learning based on the above information (the information received from the fixation sensing unit 12, the determination of whether the inside of the pump casing 11 is corroded or not, the determination of whether the inside of the pump casing is corroded or not, and the authenticity of the above determination information), learns the error condition, learns the turbidity state and the resistance state when the actual corrosion and fixation are sensed. Thus, even when the turbidity value and the resistance value are abnormally detected by the simple machine failure of the fixation sensing portion 12, it is possible to distinguish and determine whether or not fixation is occurring.
The control unit 20 executes the deep learning to adjust a reference value for determining whether the inside of the pump casing 11 is corroded or fixed. Depending on the season or the placement position of the pump, the pump attachment sensing system 100 of the present invention may affect the turbidity or resistance of the internal fluid even if corrosion does not occur, and even if the information on this cannot be received directly from the user, the reference value can be automatically adjusted to improve the accuracy of detection.
Next, the pipeline of the present invention will be described with reference to fig. 4.
The high-safety fire pump system 1000 of the present invention includes the pump-fixation sensing system 100 including the above-described fixation sensing function pump 10, and includes: a water tank 200 for storing a fluid; and an injection part 300 which receives the fluid from the fixation sensing function pump 10 and injects the fluid to the outside. The pipeline includes a piping section 400 and a valve section 500 coupled to the piping section 400 to adjust the opening and closing of the piping section 400. The piping section 400 includes a circulation pipe 410 and a spray pipe 420, and when the circulation pipe 410 is opened, the anchor sensing function pump 10 and the water tank 200 are connected to circulate the fluid through the anchor sensing function pump 10 and the water tank 200. As shown in fig. 4, the circulation pipe 410 includes a pipe for moving the fluid from the fixing and sensing function pump 10 to the water tank 200 and a pipe for moving the fluid from the water tank 200 to the fixing and sensing function pump 10, and more than 2 pipes may be arranged, or one pipe for moving the fluid in both directions may be arranged. The injection pipe 420 connects the fixation sensing function pump 10 and the injection part 300, and injects the fluid discharged from the fixation sensing function pump 10 to the outside.
Preferably, the control unit 20 controls the valve unit 500 to open the injection pipe 420 and close the circulation pipe 410 in a state where corrosion and fixation inside the pump case 11 are not judged, i.e., at ordinary times. This is to facilitate the injection of fluid from the inside of the anchor sensing function pump 10 to the outside when it is desired to inject and transfer fluid to the outside of the pipeline, such as in a fire situation.
When the control unit 20 determines that the pump casing 11 is corroded or stuck, the control unit 20 controls the valve unit 500 to close the injection pipe 420 and open the circulation pipe 410, thereby circulating the fluid in the interior of the stuck sensing function pump 10, and preventing foreign matter generated by the corrosion from being stuck to the impeller in the interior of the stuck sensing function pump 10. At this time, the circulated fluid is reused, so that the waste of fluid caused by the additional driving of the anchor sensing function pump 10 can be reduced.
In this case, the fluid discharged from the fixation sensing function pump 10 is preferably sucked into the suction port of the fixation sensing function pump 10 through the water tank 200. In the case of using the fixation sensing function pump 10 for fire protection, a large force is required, and thus the discharge flow rate is very large, and in the case of being sucked into the suction port without reducing the discharge flow rate, the load applied to the suction port becomes large, and thus the life of the pump housing 11 may be shortened. Accordingly, the fluid is sucked into the fixation sensing function pump 10 through the water tank 200, so that the load of the suction port is reduced, and the fixation sensing function pump 10 can be used more stably for a longer period of time. Further, the inside of the sump 200 includes a filtering means, thereby being capable of filtering foreign matters suspended in the fluid by corrosion, and thus being used for a longer time without changing the fluid.
The high-safety fire pump system 1000 includes a pressure gauge 600, a flow meter 700, a speedometer 800, and a water level sensor 900, which send information to the control unit 20. The pressure gauge 600 is coupled to the injection pipe 420 to detect the fluid pressure inside the injection pipe 420, the flow meter 700 is coupled to the circulation pipe 410 to detect the flow rate inside the circulation pipe 410, and the speed gauge 800 is coupled to the outlet of the pump housing 11 to detect the flow rate of the discharge port of the sessile sensing function pump 10. In addition, a water level sensor 900 is attached to the inside of the water tank 200 to sense the water level inside the water tank 200.
The pressure gauge 600 and the flow meter 700 send information to the control unit 20 to feed back whether the injection pipe 420 and the circulation pipe 410 are opened or not, so that the control unit 20 effectively adjusts the fluid pressure of the injected fluid and the flow rate of the circulated fluid. The speedometer 800 also makes the control unit 20 determine whether or not the fixation sensing function pump 10 is operating normally. The water level sensor 900 transmits the amount of fluid in the water tank 200 to the control unit 20 in real time, thereby preventing a situation where fluid having a certain height or more is injected into the water tank 200 and overflows from the water tank 200, and the control unit 20 opens the water tank 200 when fluid having a certain height is injected into the water tank 200, thereby discharging fluid from the water tank 200 at a certain flow rate and circulating the fluid inside the anchor sensing function pump 10 without another pump.
The valve part 500 is disposed at the circulation pipe 410 and the injection pipe 420, respectively. The valve part 500 is a valve disposed in either the circulation pipe 410 or the injection pipe 420. For example, as shown in fig. 4, in the case where only the injection pipe 420 is provided with a valve, when the valve of the injection pipe 420 is opened, so that the fluid of the anchor sensing-function pump 10 flows toward the injection pipe 420, and the fluid does not naturally flow toward the circulation pipe 410. Conversely, when the valve of the ejector tube 420 is closed, the fluid of the anchor sensing function pump 10 flows to the circulation tube 410, and thus the circulation tube 410 is opened.
The valves of the valve unit 500 are disposed in the injection pipe 420 and the circulation pipe 410, respectively. This can prevent the occurrence of an abnormality in either one of the two valves, which would cause the fluid to flow to the injection pipe 420 and the circulation pipe 410 or not to flow to the injection pipe 420 and the circulation pipe 410, respectively.
The valve of the valve unit 500 is disposed at the lower end of the water tank 200. This is for the following purpose: when fluid circulates between the fixation sensing function pump 10 and the water tank 200 to prevent fixation of the fixation sensing function pump 10, the control unit 20 opens the water tank 200 when fluid of a certain height is injected into the water tank 200, and thereby the fluid is discharged from the water tank 200 at a certain flow rate and circulates inside the fixation sensing function pump 10 without requiring an additional pump.
The method of the present invention will be described below with reference to fig. 5 to 8.
As shown in fig. 5, the method of using the high-safety fire pump system 1000 includes an information receiving step, an analyzing and judging step, a mode setting step and an executing step. The information receiving step is a step in which the control section 20 receives information from the fixation sensing unit. As shown in fig. 6, the information receiving step includes a resistance receiving step in which the control unit 20 receives a resistance value of the fluid from the resistance detecting device, and a turbidity receiving step in which the control unit 20 receives a turbidity value of the fluid from the turbidity detecting device. Preferably, the resistance receiving step and the turbidity receiving step are performed simultaneously and are performed from time to time. In addition, in the case where only any one of the resistance detection unit 12a and the turbidity detection unit 12b is attached to the inside of the fixation sensing function pump 10 applied to the high-safety fire pump system 1000, a part of the steps may be omitted in accordance therewith.
The analysis and judgment step is a step in which the control section 20 analyzes the information received from the fixation sensing unit to judge whether the inside of the pump casing 11 is corroded or fixed. At this time, the control unit 20 eventually determines that corrosion has occurred in the interior of the fixation sensing function pump 10 when the state is continued for a predetermined time or longer in order to eliminate erroneous measurement, even if a state is received in which the turbidity of the fluid is equal to or higher than a predetermined reference or the resistance value is equal to or lower than a predetermined reference, based on the turbidity and the resistance value of the fluid received from the fixation sensing unit 12.
The control unit 20 determines whether or not the pump casing 11 is corroded or fixed based on the reference value adjusted by the deep learning based on the stored data and the current state of the turbidity and resistance change of the fluid. Thus, even when the simple fixation sensing unit 12 detects the turbidity value and the resistance value abnormally due to a machine failure, it is possible to distinguish and determine whether fixation is occurring, and in a state where corrosion is not occurring according to the season or the arrangement position of the pump, when the turbidity or the resistance of the internal fluid is affected, even if the information on this is not directly received from the user, it is possible to automatically adjust the reference value and improve the accuracy of detection.
The mode setting step is a step of setting the mode of the high-safety fire pump system 1000 based on the information analyzed by the control unit 20. In the mode setting step, when it is determined in the analysis and determination step that corrosion or fixation has occurred, the control unit 20 sets the mode of the high-safety fire pump system 1000 to a circulation mode in which fluid is caused to travel along the circulation pipe 410 to and from the fixation sensing function pump and the water tank 200, and when it is determined in the analysis and determination step that corrosion or fixation has not occurred, it is preferable to set the mode of the high-safety fire pump system 1000 to an injection mode in which fluid is injected through the injection pipe 420.
The execution step is 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, in the case where the mode set in the mode setting step is the circulation mode, as shown in fig. 7, the performing step includes an injection pipe 420 closing step and a circulation pipe 410 opening step, a circulation flow rate adjusting step, a water level sensing step of the water tank 200, and a water tank 200 opening step.
In the injection pipe 420 closing step, the control part 20 controls the valve part 500 to close the injection pipe 420, thereby preventing the fluid from being transferred to the outside, and in the circulation pipe 410 opening step, the control part 20 controls the valve part 500 to open the circulation pipe 410, thereby circulating the fluid between the fixation sensing function pump 10 and the water tank 200. At this time, the injection tube 420 closing step and the injection tube 410 opening step may be simultaneously performed, and the valve of the valve part 500 controlled by the control part 20 is disposed at either one of the injection tube 410 or the injection tube 420. For example, only in the case where the injection pipe 420 is provided with a valve, when the valve of the injection pipe 420 is opened, and the fluid of the anchor sensing function pump 10 flows toward the injection pipe 420, and the fluid does not naturally flow toward the circulation pipe 410. Conversely, when the valve of the injection pipe 420 is closed, the fluid of the anchor sensing function pump 10 flows to the circulation pipe 410, and thus the circulation pipe 410 is opened.
The valves of the valve unit 500 are disposed in the injection pipe 420 and the circulation pipe 410, respectively, and the injection pipe 420 closing step is performed preferentially to the circulation pipe 410 opening step. This prevents the fluid from flowing to the outside of the high-safety fire pump system 1000, and thus prevents the fluid from flowing to the injection pipe 420 and the circulation pipe 410 or from flowing to the injection pipe 420 and the circulation pipe 410, respectively, due to an abnormality occurring in either one of the two valves.
In the circulation flow rate adjustment step, the control unit 20 compares the flow rate information of the flow meter 700 connected to the circulation pipe 410 with the flow rate information in the predetermined circulation mode, and controls the anchor sensing function pump 10 to adjust the flow rate when the flow rate information received from the flow meter 700 is greater or less than the flow rate information in the predetermined circulation mode.
In the water level sensing step and the water level sensing step of the water tank 200, the control unit 20 receives the water level information inside the water tank 200 from the water level sensor 900 inside the water tank 200, and when the water level of the water tank 200 is equal to or higher than a predetermined value, can open the circulation pipe 410 connecting the water tank 200 and the suction port of the fixation sensing function pump 10. This is to cause the control unit 20 to open the water tank 200 when a fluid of a certain height is injected into the water tank 200, thereby discharging the fluid from the water tank 200 at a certain flow rate and circulating the fluid inside the fixation sensing function pump 10 without requiring an additional pump.
The execution steps in the case where the mode set in the mode setting step shown in fig. 8 is the injection mode include a circulation pipe 410 closing step and an injection pipe 420 opening step, and a fluid pressure adjusting step.
In the spray pipe 420 opening step, the control part 20 controls the valve part 500 to open the spray pipe 420, thereby preventing the fluid from being transferred to the outside, and in the circulation pipe 410 closing step, the control part 20 controls the valve part 500 to close the circulation pipe 410, thereby circulating the fluid in the fixation sensing function pump 10 and the water tank 200. At this time, the injection pipe 420 opening step and the injection pipe 410 closing step may be simultaneously performed, and the valve of the valve part 500 controlled by the control part 20 is disposed at either one of the injection pipe 410 or the injection pipe 420. For example, only in the case where the injection pipe 420 is provided with a valve, when the valve of the injection pipe 420 is opened, and the fluid of the anchor sensing function pump 10 flows toward the injection pipe 420, and the fluid does not naturally flow toward the circulation pipe 410. Conversely, when the valve of the injection pipe 420 is closed, the fluid of the anchor sensing function pump 10 flows to the circulation pipe 410, and thus the circulation pipe 410 is opened.
The valves of the valve unit 500 are disposed in the injection pipe 420 and the circulation pipe 410, respectively, and the circulation pipe 410 closing step is executed in preference to the injection pipe 420 opening step. This prevents the fluid to be injected from flowing into the water tank 200 and accumulating, and prevents the fluid from flowing into the injection pipe 420 and the circulation pipe 410 or not flowing into the injection pipe 420 and the circulation pipe 410, respectively, due to an abnormality occurring in either one of the two valves.
In the fluid pressure adjustment step, the control unit 20 compares information of the fluid pressure gauge connected to the injection pipe 420 with information of the fluid pressure in a predetermined injection mode, and controls the fixation sensing function pump 10 and the valve unit 500 so that the fluid pressure in the injection pipe 420 is kept constant. Thus, the fluid is ejected to the outside at a constant fluid pressure, and the degree of the fluid pressure applied to the inside of the pipe is adjusted to reduce the load applied to the pipe.
