Problems solved by technology

[0011] In addition, the dead angle formed near the exhaust port 7b will also form a recirculation area for the gaseous refrigerant, causing the compressed gaseous refrigerant to re-expand, resulting in pressure loss
[0012] In addition, the vortex generated by the gaseous refrigerant will also generate relatively large noise at the exhaust port 7b

Abstract

The exhaust structure of a rotary vane type compressor comprises a cylinder, an accessory bearing plate, exhausts, and an inserter, with the said accessory bearing plate set under the cylinder that has a ring space, and the said exhausts go through the accessory bearing plate respectively to connect with the ring space, forming steps at its side of the interior, the said inserter inserting to the step respectively through the interior of corresponding exhausts to avoid the gas cold media vertex caused by the step. It can not only prevent the occurrence of dead end for the flow of the cold media under the step of the exhaust, but also avoid the production of vortex of the compressed gas cold media and therefore counter back the recirculation area of the gas cold media on the step and the pressure loss due to inflation of the gas cold media and meanwhile significantly reducing the fluid noise resulted and vortices.

Description

technical field [0001] The invention relates to a compressor, in particular to a structure of an exhaust port of a rotary vane compressor. Background technique [0002] Fig. 1 is the longitudinal sectional view of the overall structure of the existing rotary vane compressor; [0003] As shown in FIG. 1 , the existing rotary vane compressor generally sucks the refrigerant through the lower suction pipe 11 , and discharges the refrigerant through the upper discharge pipe 12 after being compressed. Therefore, the parts of the existing rotary vane compressor are vertically arranged inside a housing 1, including: a rotary shaft 6, a drive device D, a rotary blade 4 and a compression device P; Under the support of the bearing plate 7 and the secondary bearing plate 7a, it rotates, and its lower part contains an eccentric portion 6a; the drive device D is arranged above the rotating shaft 6, including: the rotor 3 and the stator 2, which can be turned on after the power is turned ...
