DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] like Figures 1 to 4 As shown, in order to improve the energy efficiency and optimize the work of the equipment, the utilization rate of the energy consumption of the water pump system is improved, and at the same time, the heat generated by the work of the system can be effectively utilized to avoid energy waste, which is more energy-saving and environmentally friendly. Furthermore, an energy-saving optimization system for a dynamic auxiliary equipment provided in this embodiment includes a main power system A and an auxiliary system B. The auxiliary system B is used to perform heat exchange on the power end of the main power system A. The main power system A includes a water pump 1 and a temperature sensor 2. The signal sensing end of the temperature sensor 2 is arranged on the power working end of the water pump 1 to detect the working temperature of the power working end of the water pump 1. When the working temperature of the water pump 1 exceeds the preset temperature threshold, the auxiliary system B is started to recover the heat generated by the work of the water pump 1. The auxiliary system B realizes heat exchange by transmitting a refrigerant agent, and includes a compressor 10, The condenser 11, the first electronic valve 12, the second electronic valve 13 and the heat absorption pipeline 14, the pipeline outlet end of the compressor 10 is connected to the first inlet end of the condenser 11, the first outlet end of the condenser 11 is connected to the inlet end of the first electronic valve 12, the outlet end of the first electronic valve 12 is connected to the pipeline inlet end of the heat absorption pipeline 14, the pipeline outlet end of the heat absorption pipeline 14 is connected to the inlet end of the second electronic valve 13, the outlet end of the second electronic valve 13 is connected to the pipeline inlet end of the compressor 10, and the heat absorption pipeline 14 is laid under the power working end of the water pump 1 to absorb the heat generated by the water pump 1 when doing work.

[0028] Among them, the power working end of the water pump 1 includes the motor end, the impeller end, the rotating shaft and other transmission parts that are easy to generate work heat. After working for a long time, the power working end of the water pump 1 will cause the work efficiency to decrease or the motor to be damaged due to overheating. By setting the temperature sensor 2, the working temperature of the power working end of the water pump 1 can be monitored. When the working temperature of the water pump 1 exceeds the preset temperature threshold, the auxiliary system B is started to recover the heat generated by the work of the water pump 1. Among them, the refrigerant can be Freon. At this time, the compressor 10 compresses the refrigerant in the pipeline. After opening the valve of the first electronic valve 12, the refrigerant flows toward the heat absorption pipeline 14 due to the pressure being released. The refrigerant passes through the condenser 11 from the compressor 10, can be cooled and cooled, and becomes a normal temperature high-pressure liquid, and then enters the heat absorption pipeline 14 through the pipeline from the outlet end of the first electronic valve 12. At this time, the refrigerant will absorb the heat generated by the working end of the water pump 1 through the heat absorption pipeline 14, helping the water pump 1 to achieve heat dissipation and cooling. After absorbing heat, the refrigerant will change from a normal temperature and high pressure liquid to a high temperature and low pressure gas. Then, the valve of the second electronic valve 13 is opened, and the refrigerant enters the compressor 10 through the pipeline from the outlet end of the second electronic valve 13. At this time, after the refrigerant is compressed by the compressor 10, it changes from a high temperature and low pressure gas to a high temperature and high pressure gas or a high temperature and high pressure liquid, and then changes to a normal temperature and high pressure liquid after the cooling and cooling effect of the condenser 11. The auxiliary system B performs a heat absorption cooling cycle through the above loop, so that the energy-saving optimization system of the auxiliary equipment has better heat dissipation when working, and avoids the motor from being overheated and causing the efficiency to be reduced or even damaged. Through the above process, the energy efficiency and optimization work of the equipment are improved, and the utilization rate of the energy consumption of the water pump system is improved. At the same time, the heat generated by the system working can be effectively utilized to avoid energy waste, which is more energy-saving and environmentally friendly.

[0029] In other examples, as a further improvement, the main power system A may further include a first pressure sensor 3, a second pressure sensor 4, a flow sensor 5 and a multi-function electric meter 6. The first pressure sensor 3 is arranged on the pipeline inlet end of the water pump 1, and the second pressure sensor 4 and the flow sensor 5 are respectively arranged on the pipeline outlet end of the water pump 1. The water pump 1 is provided with a multi-function electric meter 6 for collecting the power supply parameters of the water pump 1, including current, voltage, power, power factor and electric energy data. Through the above structure, the pipeline pressure, flow and power supply parameters in the main power system A can be obtained, which is convenient for calculating and optimizing the energy efficiency of the equipment.

[0030] In order to improve the energy efficiency and optimization of the equipment, effectively reduce the complexity of the energy consumption analysis of the water pump system, and improve the efficiency of the energy consumption analysis of the water pump system, further, the main power system A includes an edge computing module 7 and a cloud platform 8. The edge computing module 7 is used to synchronously collect data signals from the first pressure sensor 3, the second pressure sensor 4, the flow sensor 5, and the multi-function electric meter 6, and transmit the data signals to the cloud platform 8. The cloud platform 8 calculates the energy consumption of the main power system A according to the data signals collected by the edge computing module 7. The edge computing module 7 can perform energy consumption analysis according to the data signals collected by the first pressure sensor 3, the second pressure sensor 4, the flow sensor 5, and the multi-function electric meter 6, thereby improving the energy efficiency and optimization of the equipment, effectively reducing the complexity of the energy consumption analysis of the water pump system, and improving the efficiency of the energy consumption analysis of the water pump system.

[0031] The calculation formula of water pump efficiency is:

[0032]

[0033] P 有 =ρ×g×Q×H×10 -3 (1.2);

[0034] P 轴 =P 电 ×η 电 ×η 传 (1.3);

[0035] H=(P2-P1) / ρ×g+Z2-Z1(1.4);

[0036]

[0037] In formula (1.1): η is the pump efficiency, the unit is 100%; P 有 P is the effective power (output power) of the water pump, in kilowatts (kW); 轴 is the pump shaft power (input power), in kilowatts (kW);

[0038] In formula (1.2): ρ is the fluid density, in kilograms per cubic meter (kg / m3); g is the fluid gravity acceleration, g = 9.81m / s2; Q is the pump flow rate, in cubic meters per second (m3 / s); H is the pump head, in meters (m);

[0039] In formula (1.3): P 电 is the water pump motor power, in kilowatts (kW); η 电 is the motor efficiency of the water pump, the unit is 1; η 传 is the mechanical transmission efficiency of the water pump, the unit is 100%;

[0040] In formula (1.4): P1 is the liquid pressure at the pump inlet, in Pascals (Pa); P2 is the liquid pressure at the pump outlet, in Pascals (Pa); Z1 is the height of the pump inlet, in meters (m); Z2 is the height of the pump outlet, in meters (m);

[0041] In formula (1.5): U 实 is the actual operating voltage of the water pump motor, in volts (V); I 实 is the actual operating current of the water pump motor, in ampere (A); cosθ is the power factor of the water pump motor;

[0042] The edge computing module 7 obtains the actual energy consumption data of the water pump through the above process, and at the same time calls the data in the knowledge base of water pump fault diagnosis and energy efficiency standards in the cloud platform 8, and obtains the energy efficiency analysis and fault diagnosis results after energy efficiency analysis and comparison between the two. The edge computing module 7 can also use the display module to display the results in real time, and issue real-time warnings or alarms according to preset fault conditions.

[0043] Based on the results of energy efficiency analysis and fault diagnosis, the edge computing module 7 outputs a control signal to the drive motor of the water pump 1 according to the preset control rules to control the start and stop of the equipment. At the same time, according to the preset process control requirements, the current flow and temperature data are used for logical operations and PID operations, and the control signal is output to the drive motor of the water pump 1 according to the operation results to adjust the equipment operation state, thereby realizing the integrated measurement of energy efficiency and safety of dynamic auxiliary equipment.

[0044] Preferably, the main power system A includes a timer 9, and a pressure regulating switch 15 is provided on the compressor 10. The edge computing module 7 calculates the temperature change value per unit time according to the time parameter of the timer 9 and the temperature parameter of the temperature sensor 2. When the temperature change value exceeds the preset temperature change threshold, the pressure of the compressor 10 is increased through the pressure regulating switch 15 to increase the flow rate of the refrigerant. By providing the pressure regulating switch 15, it is convenient to adjust the pressure of the refrigerant, so that the flow rate of the refrigerant can be changed by adjusting the pressure according to the demand, and the refrigerant flow rate can be increased to achieve rapid cooling of the power working end of the water pump 1.

[0045] As a further improvement, in other embodiments, when the main power system A works normally at different preset input powers and different gears, the temperature of the water pump 1 can be controlled within a preset range by controlling different refrigerant flow rates. In other words, as the preset input power increases, that is, the speed increases, the flow rate of the refrigerant needs to be increased to control the temperature of the water pump 1 within a preset range. The refrigerant flow rate can be learned from the actual working process of the water pump 1. Specifically, in actual work, a gear is input for normal operation. When the preset temperature is reached, the flow rates of different refrigerants are input from small to large to determine whether the temperature of the water pump 1 can be controlled within a preset range (for example, within 40 to 50 degrees Celsius). If so, the flow rate of the corresponding refrigerant is associated with the corresponding gear. Otherwise, the flow rate test adjustment is continued to establish a matching relationship between the refrigerant flow rate and the corresponding power gear under the temperature threshold condition. Repeat the above steps until all gears obtain the corresponding refrigerant flow rate. The advantage of this is that the accurate flow rate can be obtained in real time under different use conditions according to the actual use conditions of the water pump, which has a greater impact on its temperature, and the interference caused by environmental factors can be reduced. Generally speaking, through the above corresponding settings, the water pump 1 can control the temperature within a preset range at different powers.

[0046] 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. When the temperature exceeds the preset temperature range, for example, when it exceeds 50 degrees Celsius, it can be further determined that the water pump 1 or one of the auxiliary systems B may have a fault, and then an alarm is issued. For example, when one of the blades in the water pump 1 is damaged, or the rotating shaft is offset, the rotating shaft will deviate and increase the friction, causing the water pump 1 to overheat; for another example, when the heat absorption pipeline 14 is broken, it will also cause the refrigerant to be lost, causing the water pump 1 to overheat. At this time, it can be roughly determined whether it is the water pump 1 that is at fault or the auxiliary system B in combination with the energy consumption data of the water pump system. Specifically, if the energy consumption data of the water pump system also produces an abnormality at this time, it can be determined that the water pump 1 is at fault, otherwise it is the auxiliary system B that is at fault. The advantage of this is that different faults in the system of the present invention can be predicted in advance, so that corresponding responses and repairs can be made quickly.

[0047] Preferably, the heat absorption pipeline 14 includes an input pipeline 141, a heat exchange pipeline 142 and an output pipeline 143. The heat exchange pipeline 142 is laid under the power working end of the water pump 1 to absorb the heat generated by the water pump 1. The outlet end of the first electronic valve 12 is connected to 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 to 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 to achieve heat dissipation and cooling of the motor. At this time, after the refrigerant absorbs heat, it will change from a normal temperature and high pressure liquid to a high temperature and low pressure gas, and then flow out of the heat exchange pipeline 142 through the output pipeline 143, thereby taking away the heat generated by the power working end of the water pump 1 and further utilizing it.

[0048] Preferably, the pipe diameter of the input pipe 141 is smaller than the pipe diameter of the heat exchange pipe 142. After the liquid refrigerant enters the heat exchange pipe 142 with a larger pipe diameter, the space suddenly increases and the pressure decreases, and the liquid refrigerant at room temperature will be vaporized and turned into a gaseous low-temperature refrigerant, thereby absorbing a large amount of heat.

[0049] Preferably, the input pipeline 141 is configured as a capillary pipeline, and the diameter of the capillary pipeline is less than one tenth of the diameter of the heat exchange pipeline 142. After the liquid refrigerant enters the heat exchange pipeline 142 through the capillary pipeline, the space suddenly increases and the pressure decreases, and the liquid refrigerant at room temperature will be vaporized and become a gaseous low-temperature refrigerant, thereby absorbing a large amount of heat. At this time, the power working end of the water pump 1 set nearby will become cold and the temperature will be reduced. The refrigerant after absorbing heat will become a gaseous high-temperature refrigerant and flow out of the heat exchange pipeline 142 through the output pipeline 143, thereby taking away the heat of the work done by the power working end of the water pump 1 and further utilizing it.

[0050] Preferably, the heat exchange pipeline 142 is configured as a zigzag loop with winding distribution. The heat exchange pipeline 142 adopts a zigzag structure and is laid under the power working end of the water pump 1 in a serpentine shape, which increases the length of the heat exchange pipeline 142 and the contact area with the power working end of the water pump 1, ensuring a better heat absorption and cooling effect on the power working end of the water pump 1. At the same time, since the heat exchange pipeline 142 is zigzag (serpentine), more refrigerant is retained during evaporation and heat absorption, so it is suitable for a vertical continuous long-term evaporation heat absorption or reflux device.

[0051] Preferably, the second inlet end of the condenser 11 is connected to a condensing water pump 16, the second outlet end of the condenser 11 is connected to a water tank 17, and the outlet end of the water tank 17 is connected to the inlet end of the condensing water pump 16. The energy absorbed by the refrigerant from the power working end of the water pump 1 is transferred to the water circulation loop of the condenser 11 for further utilization after heat exchange in the condenser 11.

[0052] Preferably, the second outlet of the condenser 11 is connected to the inlet of the water tank 17 through the heating component 18, and the heating component 18 includes a water PTC component 181 and a heater 182. The second outlet of the condenser 11 is connected to the inlet of the heater 182 through the water PTC component 181, and the outlet of the heater 182 is connected to the inlet of the water tank 17. The condenser 11 utilizes the heat conducted by the power working end of the water pump 1 for heating, and generates heat through the heater 182 to realize external heating or heating. When the heating temperature is insufficient, the water PTC component 181 can be further started to heat the managed water to ensure that the heating temperature of the heater 182 meets the user's needs.
