Sealing structure of scroll compressor

Abstract

The invention provides a sealing structure of a scroll compressor. The sealing structure comprises a case, a static scroll plate, a balance block, a sealing pad, a main bearing, an air inlet, an air outlet, a bearing cavity, a low-pressure chamber, a high-pressure chamber, an end cover sealed in an opening in one end of the case, a dynamic scroll plate, an anti-wear pad, a cross slip ring, an engine base, a shaft and a motor, wherein the dynamic scroll plate, the anti-wear pad, the cross slip ring, the engine base, the shaft and the motor are arranged in the case. Separate treatment of two sealing parts of an existing compressor are changed into once treatment and the low-pressure chamber and the high-pressure chamber can be sealed by one sealing pad at the same time; the left side end surface of the static scroll plate and a flange surface of the case are located in the same plane and only one sealing pad is needed, so that the sealing structure is low in cost, simple in structure and small in size. The sealing pad comprises a stainless steel strip and rubber, and a convex mark is arranged on the stainless steel strip, so that the sealing effect is good.

Description

technical field [0001] The invention relates to a sealing structure of a compressor, in particular to a sealing structure of a scroll compressor. Background technique [0002] Vehicle electric semi-hermetic refrigeration compressors involve two gas-tightness issues: one is that the refrigerant in the compressor needs to be isolated from the outside air, and the seal at the joint of the flange surface of the shell usually uses an O-ring Or rubber gasket seal; the second is the seal between the high pressure part and the low pressure part of the compressor, usually using O-ring seal. [0003] At present, the existing technology is to process the above two seals separately, which increases the cost and the complexity of the structure. Contents of the invention [0004] Based on this, it is necessary to provide a scroll compressor sealing structure with low cost and simple structure for the disadvantages of existing compressors such as high cost and complex structure.
