Oil way structure and scroll compressor

Abstract

The invention provides an oil way structure and a scroll compressor. A dynamic scroll disc, a support frame structure and a motor assembly are included. A backpressure cavity is formed between the dynamic scroll disc and the support frame structure. An oil storage area is arranged in a cavity where the motor assembly is located. The support frame structure is provided with a first oil introducingchannel. The oil storage area communicates with the backpressure cavity through the first oil introducing channel. The first oil introducing channel is used for introducing oil in the oil storage areainto the backpressure cavity. According to the oil way structure and the scroll compressor, the dynamic scroll disc, a static scroll disc and a bearing part can all achieve oil film lubrication, friction power consumption is lowered, and reliability of the compressor is improved. The oil introducing channel is simple in structure, high and low pressure throttling is not needed, and the risk of high and low pressure leakage does not exist. An oil way channel and a gas way are relatively separated, the oil discharge rate of the compressor can be lowered, and a system heat exchange effect is improved. A circulation oil way is formed, recycling of a lubricant in the compressor can be facilitated better, part machining and design are simplified, the process is simple, and safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an oil passage structure and a scroll compressor. Background technique [0002] Electric scroll compressors for automotive air conditioners are usually of a horizontal structure, that is, the motor, shafting and pump body in the compressor are installed horizontally. Compared with conventional vertical compressors, the disadvantage of horizontal compressors is that there is no stable lubricating oil pool inside the compressor. The recycling of refrigeration oil and the lubrication of bearings are difficult. [0003] Such as figure 1 In the oil circuit structure shown in the prior art, the moving plate 1', the static plate 2', and the bracket 3' are respectively provided with an oil introduction channel structure 4', which connects the back pressure chamber 5' and the exhaust high-pressure oil area 6', The follower plate 1' runs for one cycle, and the oil guide ...

AI Technical Summary

Problems solved by technology

[0004] However, on the one hand, this solution needs to store a certain amount of lubricating oil in the high pressure area, which will cause the problem of high oil discharge rate of the compressor

On the other hand, the impurities produced by the wear of the pump body in the high-pressure oil area will enter the back pressure chamber 5' through the oil channel structure 4', and the impurities may also block the oil channel, affecting the lubrication of the bracket 3', the moving plate 1', etc. , abnormal wear occurs
