Rotary compressor with compression pump separated from motor

Abstract

A rotary compressor with compression pump separated from motor comprises an inside motor and a seal shell for the compression pump, a compressor rotary shaft, and a gas-liquid separator communicating with the compression pump through an intake elbow pipe. The compression pump comprises an upper flange, a cylinder and a lower flange; the compressor rotary shaft is driven by a motor to rotate; the upper flange, the cylinder and the lower flange are successively arranged on a pump rotary shaft with an axis coinciding with that of the compressor rotary shaft; the pump rotary shaft is driven by the compressor rotary shaft to rotate; a pump cover plate fixed on an inner wall of the seal shell is arranged above the upper flange; the pump cover enables the space in the seal shell and below the pump cover plate to form a sealed high-pressure area; an exhaust pipe communicating with the high-pressure area is arranged on a side wall of the seal shell; and radiating holes are arranged on a peripheral wall of the seal shell and above the pump cover plate. According to the invention, electrical components are separated from a refrigerant, so as to improve usage safety and reliability of the compressor.

Description

technical field

[0001] The invention belongs to the technical field of compressors, in particular to a rotary compressor in which a compression pump body and a motor are separated. Background technique

[0002] A hermetic rotary compressor used in household appliances such as air conditioners usually includes a closed casing, a motor, a compressor shaft, a compression pump body, a gas-liquid separator, a suction pipe, and an exhaust pipe. Wherein, the motor is composed of a stator and a rotor, and the compression pump body communicates with the gas-liquid separator through a connecting pipe. The compression pump body in the compressor plays the role of compressing the refrigerant, which is used to suck and compress the refrigerant, and then output the high-temperature and high-pressure refrigerant. The compression pump body of the compressor usually includes cylinders, rollers, upper flanges, lower flanges and sliding vanes. The compression pump body is installed under the...
