Embodiment Construction

[0024] In the related technology, the low-temperature and low-pressure refrigerant from the refrigeration system directly enters the suction low-pressure cavity through the suction hole on the cylinder, because the gas is directly sucked into the cylinder, the refrigerant is easily heated during the suction process, and the gas will cause The volume of the gas becomes larger, so when the gas is sucked into the suction chamber, the temperature, pressure and volume of the refrigerant will be higher than expected, which will lead to a decrease in the suction capacity of the compressor during operation, a decrease in volumetric efficiency, and indirectly lead to compression Reduced performance.

[0025] To solve this problem, see Figure 1 to Figure 5 As shown, according to the embodiment of the application, the pump body structure includes a cylinder 1 and a flange, the flange has a suction hole 2 and a sealing cavity 3, the cylinder 1 has a suction chamber and a compression cham...

Abstract

The invention provides a pump body structure, a compressor and an air conditioner. The pump body structure comprises an air cylinder (1) and a flange, wherein the flange is provided with an air suction hole (2) and a sealing cavity (3), the air cylinder (1) is provided with an air suction cavity and a compression cavity, a partition wall is arranged on the side, which is close to the air cylinder (1), of the flange, a preset interval is formed between the sealing cavity (3) and the air cylinder (1) through the partition wall, a communicating hole (4) is formed in the partition wall, the sealing cavity (3) is communicated with the air suction cavity through the communicating hole (4), and a refrigerant can enter the sealing cavity (3) through the air suction hole (2) and then enter the air suction cavity through the sealing cavity (3) and the communicating hole (4). According to the pump body structure, the influence of heat generated in the exhaust process on air suction can be reduced, the volume efficiency of compression is guaranteed, and the energy efficiency of the compressor is improved.

Description

technical field [0001] The present application relates to the technical field of compressors, in particular to a pump body structure, a compressor and an air conditioner. Background technique [0002] Due to the characteristics of simple structure, low cost and high reliability, rolling rotor compressors are more and more widely used in air conditioners, heat pump water heaters, refrigeration equipment, vehicle air conditioners and other fields. [0003] The main function of the rolling rotor compressor in the field of air conditioners is to periodically compress the refrigerant, so that the low-temperature and low-pressure refrigerant is compressed into a high-temperature and high-pressure refrigerant to promote its circulation in the air conditioner. During the periodic compression and exhaust process of the rolling rotor compressor, the high-temperature and high-pressure gas in the pump body and the heat generated during the compression and exhaust process will have a hea...
