Description

Technical Field

[0001] This application relates to the field of circulating water pumps, and in particular to an energy-saving device for a circulating water pump in an energy-saving air-cooled modular unit central air conditioning system. Background Technology

[0002] Energy-saving air-cooled modular units are high-efficiency and energy-saving air conditioning equipment. They adopt air-cooling technology, using air as the cold (heat) source and water as the cooling (heat) medium. Central air conditioning circulating water pumps are devices used to drive the water circulation in the central air conditioning water system. Their main function is to convert mechanical energy into fluid kinetic energy to maintain the continuous flow of the medium in a closed or open system to meet temperature regulation, pressure balance, or process requirements. Circulating water pumps are installed at heat stations (heat centers), heat sources, or cold sources. In the closed loop of the heating or air conditioning water system, the circulating water pump does not lift the water to a high place, but rather makes the water circulate repeatedly within the system, overcoming the resistance loss of the loop. When using a conventional circulating water pump, after the fixed base is installed stably, a rotating motor and the circulating water pump body are installed on the top of the fixed base. The output end of the rotating motor is connected to one end of the circulating water pump body, connecting the circulating water pump body to the central air conditioning system. After the rotating motor starts, it controls the water flow within the circulating water pump body, thereby circulating the water in the central air conditioning system.

[0003] Regarding the aforementioned technologies, the inventors believe that when a central air conditioner is in heating mode, the ambient temperature is low, making it difficult for the circulating water pump to generate heat and resulting in low energy consumption. However, when the ambient temperature is high, the circulating water pump is prone to overheating, causing the electrical energy of the circulating water pump to be converted into heat energy, thus increasing the energy consumption of the circulating water pump.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem of excessive energy consumption caused by overheating of circulating water pumps, this application provides an energy-saving device for circulating water pumps in central air conditioning units with energy-saving air-cooled modular units.

[0006] The energy-saving device for the circulating water pump of a central air conditioning unit in this application adopts the following technical solution:

[0007] An energy-saving device for a circulating water pump in a central air conditioning unit with air-cooled modular design includes a fixed base and an inlet pipe. A rotating motor and a circulating water pump body are fixedly installed on the top of the fixed base. The output end of the rotating motor is fixedly connected to one end of the circulating water pump body. One end of the inlet pipe is connected to an outlet pipe. Connecting pipes are connected to the surfaces of both the inlet and outlet pipes. A heat dissipation pipe is connected to one end of the connecting pipe. The surface of the heat dissipation pipe is movably connected to the surface of the rotating motor. One end of both the inlet and outlet pipes is fixedly installed to one end of the circulating water pump body. The cross-section of the connecting pipe is L-shaped. The dimensions of the heat dissipation pipe are compatible with the dimensions of the rotating motor.

[0008] Preferably, a mounting ring is fixedly connected to the surface of the rotating motor. The mounting ring is a rubber ring, and the surface of the mounting ring is movably mounted to the surface of the heat sink.

[0009] Preferably, the inner wall of the mounting ring is fitted with a plurality of fixing bolts, which are arranged in a circular array around the center of the mounting ring, and the surfaces of the fixing bolts are threadedly connected to the inner wall of the rotating motor.

[0010] Preferably, an electric control valve is fixedly installed on the surface of the connecting pipe, and the electric control valve is composed of a valve body and an electric actuator.

[0011] Preferably, a temperature detector is fixedly connected to the surface of the water inlet pipe, and one end of the temperature detector is electrically connected to one end of the electric control valve via a wire.

[0012] Preferably, a connecting ring is rotatably installed at one end of the connecting pipe, and a threaded ring is threadedly connected to the inner wall of the connecting pipe. One end of each of the two threaded rings is fixedly installed to the inner wall surface of the inlet pipe and the outlet pipe, respectively.

[0013] Preferably, a sealing ring is fixedly connected to the inner wall of the connecting ring. The sealing ring is a rubber ring, and one end of the sealing ring is movably installed with one end of the threaded ring.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing the inlet and outlet pipes at opposite ends of the circulating water pump body, and connecting the surfaces of both pipes to heat dissipation pipes via connecting pipes, cold water entering the inlet pipe is introduced into the heat dissipation pipes to cool the rotating motor on the surface of the heat dissipation pipes. A rubber mounting ring is installed on the surface of the rotating motor to prevent abnormal noise caused by water flow when the mounting ring contacts the rotating motor. Several fixing bolts are secured to the inner wall of the mounting ring for easy replacement after removing the bolts. Compared to existing technologies, this method effectively improves the energy-saving effect of the circulating water pump.

[0016] 2. An electric control valve can also be installed on the surface of the connecting pipe to control its opening and closing. A temperature detector is installed on the surface of the inlet pipe to monitor the water temperature. A connecting ring is rotatably connected to one end of the connecting pipe, and a threaded ring is threaded onto the inner wall of the connecting ring. This allows for easy disassembly of the connecting pipe after separating the connecting ring from the threaded ring, facilitating subsequent cleaning and replacement. A rubber sealing ring is installed on the inner wall of the connecting ring to improve the sealing between the connecting ring and the threaded ring, effectively enhancing the performance of the device.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses an energy-saving device for the circulating water pump of a central air conditioning unit in an energy-saving air-cooled modular unit, referring to... Figure 1 - Figure 2The system includes a fixed base 1. During use, after the fixed base 1 is installed stably, a rotating motor 2 and a circulating water pump body 3 are installed on the top of the fixed base 1. The output end of the rotating motor 2 is connected to one end of the circulating water pump body 3, connecting the circulating water pump body 3 to the central air conditioning system. After the rotating motor 2 starts, it controls the water flow in the circulating water pump body 3, thereby circulating the water in the central air conditioning system. The inlet pipe 4 and the outlet pipe 5 are respectively installed at both ends of the circulating water pump body 3. The surfaces of the inlet pipe 4 and the outlet pipe 5 are connected to a connecting pipe 6. One end of the connecting pipe 6 is connected to a heat dissipation pipe 7. The cold water entering the inlet pipe 4 is introduced into the heat dissipation pipe 7 through the connecting pipe 6, thereby cooling the rotating motor 2 on the surface of the heat dissipation pipe 7 and avoiding the problem of overheating of the rotating motor 2 when the external environment is hot, which would lead to increased energy consumption.

[0024] Reference Figure 2 A rubber mounting ring 8 is installed on the surface of the rotating motor 2. The surface of the mounting ring 8 is connected to the surface of the heat sink 7. The mounting ring 8 supports the heat sink 7 and avoids the problem of abnormal noise caused by water flow when the mounting ring 8 is in contact with the rotating motor 2. Several fixing bolts 9 are snapped into the inner wall of the mounting ring 8. The surface of the fixing bolts 9 is threaded to the inner wall of the rotating motor 2. The mounting ring 8 is connected to the surface of the rotating motor 2 by the fixing bolts 9. The mounting ring 8 can be easily replaced after the fixing bolts 9 are removed.

[0025] Reference Figure 3 - Figure 4 An electric control valve 10 is installed on the surface of the connecting pipe 6. The electric control valve 10 controls the opening and closing of the connecting pipe 6, making it convenient to control the opening or closing of the device according to actual use. A temperature detector 14 is installed on the surface of the water inlet pipe 4. The temperature detector 14 detects the water temperature in the water inlet pipe 4, and controls the opening and closing of the electric control valve 10 according to the water temperature, thus preventing hot water from entering the heat dissipation pipe 7. A connecting ring 11 is rotatably connected to one end of the connecting pipe 6. A threaded ring 12 is threadedly connected to the inner wall of the connecting ring 11. One end of the threaded ring 12 is connected to the surface of the water inlet pipe 4 and the water outlet pipe 5. The connecting pipe 6 is installed using the threaded ring 12 and the connecting ring 11. After separating the connecting ring 11 and the threaded ring 12, the connecting pipe 6 can be disassembled for easy cleaning and replacement. A rubber sealing ring 13 is installed on the inner wall of the connecting ring 11. One end of the sealing ring 13 is connected to one end of the threaded ring 12. The sealing ring 13 improves the sealing performance between the connecting ring 11 and the threaded ring 12, preventing water leakage.

[0026] The implementation principle of the energy-saving device for the circulating water pump of the central air conditioning unit of the present application embodiment is as follows: by installing the inlet pipe 4 and the outlet pipe 5 at both ends of the circulating water pump body 3, the surfaces of the inlet pipe 4 and the outlet pipe 5 are connected to the connecting pipe 6, and one end of the connecting pipe 6 is connected to the heat dissipation pipe 7, so that the cold water entering the inlet pipe 4 can be introduced into the heat dissipation pipe 7 through the connecting pipe 6, thereby cooling the rotating motor 2 on the surface of the heat dissipation pipe 7, avoiding the problem of overheating of the rotating motor 2 when the external environment is hot, which would lead to increased energy consumption. The surface of the rotating motor 2 is equipped with a rubber mounting ring 8, and the surface of the mounting ring 8 is connected to the surface of the heat dissipation pipe 7, so as to support the heat dissipation pipe 7 with the mounting ring 8, avoiding the problem of abnormal noise caused by water flow when the mounting ring 8 and the rotating motor 2 are in contact. Several fixing bolts 9 are snapped into the inner wall of the mounting ring 8, and the surface of the fixing bolts 9 is threaded to the inner wall of the rotating motor 2, so as to connect the mounting ring 8 and the surface of the rotating motor 2 with the fixing bolts 9, and the mounting ring 8 can be easily replaced after the fixing bolts 9 are removed.

[0027] An electric control valve 10 can also be installed on the surface of the connecting pipe 6 to control the opening and closing of the connecting pipe 6. This allows for convenient control of the device's opening or closing based on actual usage. A temperature detector 14 is installed on the surface of the inlet pipe 4 to detect the water temperature within the inlet pipe 4. This allows for control of the electric control valve 10 based on the water temperature, preventing hot water from entering the radiator pipe 7. One end of the connecting pipe 6 is rotatably connected to a connecting ring 11, with the inner wall of the connecting ring 11 threaded. There is a threaded ring 12, one end of which is connected to the surface of the inlet pipe 4 and the outlet pipe 5, so as to facilitate the installation of the connecting pipe 6 by means of the threaded ring 12 and the connecting ring 11. After the connecting ring 11 and the threaded ring 12 are separated, the connecting pipe 6 can be disassembled for easy cleaning and replacement. A rubber sealing ring 13 is installed on the inner wall of the connecting ring 11, one end of which is connected to one end of the threaded ring 12, so as to improve the sealing performance between the connecting ring 11 and the threaded ring 12 and prevent water leakage.
