Embodiment Construction

[0024] refer to Figure 1 to Figure 4 , which shows the specific structure of the preferred embodiment of the present invention. The structural features of each element of the present invention will be described in detail below, and if there is a description of the direction (up, down, left, right, front and back), it is based on Figure 4 The shown structure is a reference description, but the actual use direction of the present invention is not limited thereto.

[0025] 1. In the cold state, the compressor is not working, the lubricating oil is static, and impurities, especially metal impurities, are deposited at the bottom.

[0026] 2. In the initial stage of compressor start-up operation, the moving parts are in a "dry" state, and it is very necessary to obtain lubrication with refrigeration lubricating oil.

[0027] 3. The oil pumping of the oil suction pipe has just started, and the oiling is relatively slow, so there should be no obstacles.

[0028] 4. But after the ...

Abstract

The invention discloses a self-adaptive oil filtering system of a compressor. The self-adaptive oil filtering system comprises a crankshaft and an oil suction pipe, wherein the crankshaft comprises a crankshaft part, a balance part and a spindle part; the crankshaft is provided with a spiral oil groove in the outer wall of the spindle part; an oil suction inner cavity is formed in the lower end of the spindle part; the spindle part is provided with an oil hole in the lower part of the oil groove; the oil suction pipe is provided with a direct-through inner cavity and is arranged at the lower end of the spindle part; the direct-through inner cavity of the oil suction pipe communicates with the oil suction inner cavity of the crankshaft; a mounting base is arranged inside the oil suction inner cavity, on the oil suction pipe; an oil filtering part is arranged on the inner side of the oil hole, in the oil suction inner cavity; a bimetallic strip is arranged on the mounting base; when the bimetallic strip is heated, the bimetallic strip can drive the oil filtering part to shield the oil hole; when the bimetallic strip is cooled, the bimetallic strip can drive the oil filtering part to keep away from the oil hole. According to the self-adaptive oil filtering system disclosed by the invention, the oil filtering part is arranged in the oil hole, so that the performance and the service life of the compressor are guaranteed; meanwhile, the oil filtering part is flexibly controlled to be retracted and released by using the temperature variation characteristic of the bimetallic strip, so that the lubricating problem at the start running stage of the compressor and the filtering problem after normal running of the compressor are solved.

Description

technical field [0001] The invention is used in the technical field of refrigeration compressors, and in particular relates to an adaptive oil filtering system for compressors. Background technique [0002] The interior of the compressor and the pipeline of the refrigerator system cannot be completely clean. During operation, impurities will flow back into the oil pool at the bottom of the compressor shell along with the refrigeration oil. The existing compressor oil pumping system either has no filtering device or the filtering device is fixed. In compressors without filters, impurities are free to move. When the compressor restarts to work, the oil suction pipe (oil pump) stirs the oil pool. After the impurities are slowly stirred up, they may be sucked by the oil suction pipe and transported upward to the friction pairs of moving parts, resulting in obvious negative effects: friction Increased resistance, increased wear, and even stuck. Affect the performance and life ...
