Problems solved by technology

[0007] However, the fan blades formed on the cast aluminum motor rotor of the horizontal rotary compressor cause that the motor rotor for the horizontal rotary compressor cannot be shared with the conventional vertical horizontal rotary compressor motor rotor, and special casting aluminum molds are required. Or processing equipment to manufacture the fan blades, resulting in an increase in manufacturing costs
At the same time, the excessively large processing area of ​​the rotor cast aluminum is likely to cause a decrease in the efficiency of the motor

Abstract

The invention relates to a rotary compressor and the application thereof, comprising a compression component and a motor component which are arranged inside a shell, wherein the interior of the shell is divided into three chambers by the compression component and the motor component; the motor component comprises a rotor and a stator, and the end part of the rotor is provided with a rotor end ring; the compression component includes an air cylinder, a main bearing, a secondary bearing and an eccentric crankshaft,and the center of the eccentric crankshaft is provided with a central hole which is communicated with an oil storage cavity; the rotor end ring is provided with the pressure control device which comprises a cover nut that is connected with the rotor end ring; an end ring space is surrounded by the cover nut and the rotor end ring; the cover nut is provided with an open hole and a first fan blade,and the open hole is communicated with a first motor cavity and a second motor cavity; the end ring space is communicated with one end of the central hole. The pressure control device can be separated from the rotor end ring, has good pressure reducing effect, and not only can be used for the horizontal type rotary compressor, but also the vertical rotary compressor.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to a rotary compressor and its application. Background technique [0002] The horizontal rotary compressor with the eccentric crankshaft placed in the horizontal direction has the great advantage that the overall height can be reduced compared with the vertical rotary compressor with the eccentric crankshaft placed in the vertical direction. The horizontal rotary compressor can be equipped without changing the height. The system has the advantage of increasing the effective volume. But it is precisely because the rotation center of the horizontal rotary compressor is parallel to the oil surface, so how to realize the oil supply is the key technology of the horizontal rotary compressor. [0003] As early as the 1990s, rotor fans had been formed by processing wind blades on the rotor end rings. Through the rotation of the rotors, the fans generated centrifugal force to supply the oil in the oil...
