Compressor oil return lubrication system

Abstract

The invention discloses a compressor oil return lubrication system, and relates to the technical field of scroll compressors. The compressor oil return lubrication system involves a motor shell and anend cover, a movable scroll plate, a static scroll plate and a bearing block are arranged in the motor shell, the bearing block is arranged on the left side of the static scroll plate, a cross slidering is arranged between the movable scroll plate and the bearing block, a bearing pad is arranged between the movable scroll plate and the bearing block, and the static scroll plate comprises a static scroll plate body, an inclined oil passing hole, a large oil passing hole, a bypass oil hole and a pin. According to the compressor oil return lubrication system, the bypass oil hole is arranged, the machining efficiency can be improved by using a large-diameter cutter to drill a deep hole, the pin is used for blocking the large oil hole, only a proper amount of oil passes through the bypass oilhole with smaller cross sectional area, the phenomenon of gas leakage between high and low pressure cavities of the compressor is avoided, an upper oil channel is arranged, under the action of an annular groove and a connecting groove the oil can flow back into the bearing block from the upper oil channel, and a lubricating effect can be achieved on the cross-shaped sliding ring.

Description

technical field [0001] The invention relates to the technical field of scroll compressors, in particular to a compressor oil return lubrication system. Background technique [0002] A scroll compressor is a positive displacement compressor. The compression component consists of an orbiting scroll and a stationary scroll, and includes many structural features that allow the split flow of gas through the compressor housing to reduce entrained oil. . [0003] The oil return hole of the fixed scroll of the existing scroll compressor is composed of a straight hole part and an inclined hole part. Because the straight hole is long and the hole diameter is relatively small, when the straight hole is drilled to a certain depth, the tool is easy to break , resulting in the problems of high processing cost and high rejection rate, and the oil return of the existing oil return hole generally cannot lubricate the cross slip ring, which makes the cross slip ring dry friction and reduces ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a compressor oil return lubrication system, which can reduce the processing difficulty of the oil return hole and greatly improve the yield, and can lubricate the cross slip ring through the return oil of the oil return hole, so that the service life of the cross slip ring The advantage of effective extension solves the problem that the oil return hole of the existing fixed scroll is difficult to process, the yield is low, and the Oldham slip ring cannot be effectively lubricated
