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 characteristics 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 aft...

Abstract

The invention discloses an adaptive oil filtering system for a compressor, which comprises a crankshaft and an oil suction pipe. The crankshaft includes a crankshaft part, a balance part and a main shaft part. There is an oil-absorbing cavity, and the main shaft is provided with an oil hole at the lower end of the oil groove. The oil-suction pipe has a straight-through inner cavity, and the oil-suction pipe is arranged at the lower end of the main shaft. There is a mounting seat inside the inner cavity, and an oil filter part is arranged on the inner side of the oil hole in the oil-absorbing cavity, and a bimetal sheet is arranged on the mounting seat, and the bimetal sheet can drive the oil filter part to cover the oil hole when heated; the bimetallic The blades drive the oil filter element away from the oil holes as it cools. The invention ensures the performance and life of the compressor by setting the oil filter parts in the oil hole, and at the same time flexibly controls the retractable oil filter parts through the temperature change characteristics of the bimetal sheet to solve the lubrication problem during the start-up operation stage of the compressor, and after normal operation filtering problem.

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 ...
