Refrigerator compressor with filter

Abstract

The invention provides a refrigerator compressor with a filter, which comprises a housing, a core and a core support structure, wherein the core comprises a support, a cylinder body, a crank shaft, a motor stator and a motor rotor, the cylinder body is connected with the support, the core is installed in the housing through the core support structure, and an oil sump is arranged below the core; the crank shaft comprises a crank shaft part, a balance part and a main shaft part, and the crank shaft is provided with an oil supply channel which comprises an upper oil hole, an outer oil groove, a middle oil hole and an oil suction cavity; an oil suction pipe is connected with the lower end of the crank shaft, the filter which comprises an upper ring plate, a filter screen and a fixed frame is arranged in the oil sump, and the filter is connected with a lower housing through supporting legs so that the end of the oil suction pipe penetrates through the opening of the filter screen and extends into the filter screen. The refrigerator compressor with the filter has the characteristics that lubricating oil supplied to links, pistons and other moving parts from the oil suction pipe is filtered, which can greatly reduce damage of solid impurities in the lubricating oil to the moving parts and is favorable to prolonging the service life of the refrigerator compressor; the refrigerator compressor with the filter has a simple structure, can be installed easily and has good using effects.

Description

technical field [0001] The present invention relates to refrigerator compressors. Background technique [0002] Refrigerator compressors are usually fully enclosed, and their structure refers to figure 1 , mainly including a casing and a movement placed in the casing, the casing includes an upper casing 11 and a lower casing 12; [0003] Movement comprises support 21, cylinder block 22, crankshaft, motor pad 70, rotor 7 and movement mounting bolt 71, cylinder block 22 conjoined or be connected to support 21, the cylinder 20 built-in piston 3 of cylinder block 22, motor stator 70 Including the stator core and the stator winding wound around the stator core, the stator core is fixedly connected to the lower part of the bracket 21 through the core mounting bolt 71, and the middle part of the bracket 21 is provided with a shaft hole and a bearing is installed; [0004] The crankshaft includes a crankshaft part 5, a balance part 51 and a main shaft part 6. The main shaft part 6...

AI Technical Summary

Problems solved by technology

[0009] When the existing compressor is working, there are inevitably various impurities (such as iron filings or other solids) in the pipeline of the refrigeration system. These materials fall into the lubricating oil pool and will be supplied to the moving parts with the lubricating oil. In this way, the moving parts (such as piston 3, cylinder 20, crankshaft, valve plate, etc.) will be worn and the service life of the compressor will be shortened.
