Pump body structure, compressor, air conditioner

Abstract

The invention provides a pump body structure, a compressor and an air conditioner. One of the pump body structures includes an exhaust cavity, the exhaust cavity has a first exhaust channel and a second exhaust channel, and the first exhaust channel and the second exhaust channel can be connected to the exhaust channel respectively. The air cavity is connected or cut off, and the opening and penetration pressure of the second exhaust passage is higher than the opening and penetration pressure of the first exhaust passage. The invention provides a pump body structure, a compressor, and an air conditioner. When the exhaust resistance of the compressor is too large or overcompressed, the compressor exhaust resistance and overcompression loss are reduced by opening and penetrating the second exhaust passage. Reduce the torque fluctuation caused by poor exhaust at the end of the exhaust, and reduce the air flow pulsation.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a pump body structure, a compressor and an air conditioner. Background technique [0002] The pump body assembly of the rolling rotor compressor is composed of a cylinder, a roller, a crankshaft, an upper and lower flange assembly (including an upper and lower flange, an exhaust valve plate and a valve plate limit baffle) and a sliding plate. A closed high-pressure chamber (exhaust chamber) and a low-pressure chamber (suction chamber) are formed, and the sliding vane cooperates with the sliding vane groove to reciprocate in the sliding vane groove, so that the volume of the high and low pressure chamber changes periodically, and the cylinder compression chamber approaches There is a cylinder exhaust port at the position of the sliding vane groove, and a flange exhaust port is provided at the corresponding position between the upper flange and the cylinder exh...

AI Technical Summary

Problems solved by technology

[0003] Due to the development trend of miniaturization of rotary compressors, the cylinder bore of the pump body is bound to be limited. Under the same displacement, the cylinder height increases relatively, which leads to a great increase in the exhaust resistance of the pump body, which can easily cause poor exhaust and over-compression of the pump body. As a result, the energy consumption of the compressor due to exhaust is relatively high, and in severe cases, abnormal shutdown of the compressor and other reliability problems will be caused due to excessive instantaneous torque fluctuations. Based on this problem, the present invention is proposed
