P Shaft ＝P Electric power ×η Electric power ×η Transmission device (1.3)；
H＝(P2-P1)/ρ×g+Z2-Z1(1.4)；
In formula (1.1): η is the efficiency of the water pump, and the unit is 100%; p (P) Has the following components The unit is kilowatt (kW) for the effective power (output power) of the water pump; p (P) Shaft The unit is kilowatt (kW) for water pump shaft power (input power);

the edge calculation module 7 performs actual energy consumption data of the water pump through the process, and simultaneously invokes data in the water pump fault diagnosis and energy efficiency standard knowledge base in the cloud platform 8, and performs energy efficiency analysis and comparison to obtain energy efficiency analysis and fault diagnosis results. The edge calculation module 7 can also display the result in real time by utilizing the display module, and send out real-time early warning or alarm according to the preset fault condition.
Based on the energy efficiency analysis and fault diagnosis results, the edge calculation module 7 outputs a control signal to the driving motor of the water pump 1 according to a preset control rule so as to control the start and stop of equipment. Meanwhile, according to the preset process control requirement, logic operation and PID operation are performed by utilizing the current flow temperature data, and a control signal is output to the driving motor of the water pump 1 according to the operation result so as to adjust the running state of equipment, thereby realizing the safe and integrated measurement of the energy efficiency of the movable auxiliary equipment.
Preferably, the main power system a comprises a timer 9, a pressure regulating switch 15 is arranged on the compressor 10, the edge calculating module 7 calculates a temperature change value in unit time according to a time parameter of the timer 9 and a temperature parameter of the temperature sensor 2, and when the temperature change value exceeds a preset temperature change threshold value, the pressure of the compressor 10 is increased through the pressure regulating switch 15 so as to improve the flow rate of the refrigerant agent. Through setting up pressure regulating switch 15, be convenient for adjust the pressure size of refrigerant agent to change the flow size of refrigerant agent through adjusting pressure size according to the demand, can increase refrigerant agent flow and realize quick cooling to the power working end of water pump 1.
As a further improvement, in other embodiments, when the main power system a works normally at different preset input powers and different gear positions, the temperature of the water pump 1 can be controlled within a preset range by controlling different coolant flow rates. In other words, as the preset input power increases, i.e., the rotational speed increases, the flow rate of the refrigerant agent needs to be increased to control the temperature of the water pump 1 within the preset range. The coolant flow can be learned according to the water pump 1 in the actual working process. Specifically, in actual operation, a first gear is input for normal operation, when a preset temperature is reached, the flow rates of different coolant agents are input from small to large, whether the temperature of the water pump 1 can be controlled within a preset range (for example, within 40-50 ℃), if so, the flow rates of the corresponding coolant agents are associated with the corresponding gears, and if not, flow test allocation is continuously carried out, so that a matching relationship between the coolant agent flow rates and the corresponding power gears under the temperature threshold condition is established. Repeating the steps until all gears acquire the flow of the corresponding refrigerant agent. The water pump has the advantages that accurate flow can be obtained in real time under different using conditions according to the actual using conditions of the water pump, the temperature influence is large, and the interference caused by environmental factors is reduced. In general, by the above-mentioned corresponding arrangement, the water pump 1 can control the temperature within a preset range under different power.
In other embodiments, as a further improvement, when the water pump 1 is under normal working conditions, the temperature of the water pump 1 can be further obtained through the temperature sensor 2, and when the temperature exceeds a preset temperature range, for example, exceeds 50 ℃, it can be further judged that one of the water pump 1 or the auxiliary system B is likely to have a fault, and then an alarm is given. For example, when one of the blades in the water pump 1 is damaged, or the rotation shaft is offset, the rotation shaft is offset to increase friction, so that the water pump 1 is overheated; as another example, when the heat absorption line 14 breaks, the refrigerant is lost, and the water pump 1 is overheated. At this time, it is possible to roughly determine whether the water pump 1 is malfunctioning or the auxiliary system B in combination with the water pump system energy consumption data. Specifically, if the energy consumption data of the water pump system is abnormal at this time, it can be determined that the water pump 1 is faulty, otherwise, the auxiliary system B is faulty. The method has the advantages that different faults in the system can be prejudged in advance, so that corresponding countermeasures and maintenance can be quickly made.
Preferably, the heat absorbing pipeline 14 comprises an input pipeline 141, a heat exchange pipeline 142 and an output pipeline 143, the heat exchange pipeline 142 is paved below the power working end of the water pump 1 and is used for absorbing heat generated by acting of the water pump 1, the outlet end of the first electronic valve 12 is connected with the pipeline inlet end of the heat exchange pipeline 142 through the input pipeline 141, and the pipeline outlet end of the heat exchange pipeline 142 is connected with the inlet end of the second electronic valve 13 through the output pipeline 143. The refrigerant enters the heat exchange pipeline 142 through the input pipeline 141, and exchanges heat with the power working end of the water pump 1 in the heat exchange pipeline 142, so that the heat dissipation and the temperature reduction of the motor are realized. At this time, after absorbing heat, the refrigerant agent is changed from a normal temperature and high pressure liquid state into a high temperature and low pressure gas state, and then flows out of the heat exchange pipeline 142 through the output pipeline 143, so that the heat of the working end of the water pump 1 doing work is taken away and further utilized.
Preferably, the inlet line 141 has a line diameter that is smaller than the line diameter of the heat exchange line 142. After the liquid refrigerant enters the heat exchange pipeline 142 with larger pipeline diameter, the space is suddenly increased, the pressure is reduced, the refrigerant at the liquid normal temperature is gasified and becomes the refrigerant at the low temperature, so that a large amount of heat is absorbed.
Preferably, the inlet line 141 is configured as a capillary line having a line diameter less than one tenth of the line diameter of the heat exchange line 142. After the liquid refrigerant enters the heat exchange pipeline 142 through the capillary pipeline, the space is suddenly increased, the pressure is reduced, the refrigerant at the liquid normal temperature is gasified and becomes a gaseous refrigerant at the low temperature, so that a large amount of heat is absorbed, at the moment, the power working end of the water pump 1 arranged nearby is cooled and cooled, the refrigerant after heat absorption becomes a gaseous refrigerant at the high temperature, and the gaseous refrigerant flows out of the heat exchange pipeline 142 through the output pipeline 143, so that the heat of acting at the power working end of the water pump 1 is taken away and further utilized.
Preferably, the heat exchange line 142 is configured as a zigzag loop in a coiled distribution.
