Problems solved by technology

[0016] However, when the scroll compressor is combined with the refrigeration system, there are foreign objects in the pipes or foreign objects generated in operations such as pipe welding. When the scroll compressor is running, the refrigerant is sucked into the airtight container 1 and mixed in the airtight container. In the lubricating oil 8 at the bottom of the container 1, the above-mentioned foreign matter and the lubricating oil 8 are sucked up by the lubricating oil supply device 22, and then supplied to the friction part and the bearing frame part of the compressor 30 through the lubricating oil oil passage 23, resulting in inoperability or occurrence of damaged

Abstract

A lubricating oil filter for sealed compressor features that the lubricating oil in the bottom of sealed container is supplied to the friction positions of comprssion unit via the lubricating oil supply unit at bottom of rotor shaft and the oil channel and a net filter is arranged at the bottom of rotor shaft for removing the impurities from oil.

Description

technical field [0001] The invention relates to a hermetic compressor. In particular, it relates to a lubricating oil filter device for a hermetic compressor to prevent foreign matter entering from the outside of the hermetic compressor together with the lubricating oil from entering the machine parts and bearings inside the compressor. Background technique [0002] In general, hermetic compressors can be classified into a motor that generates rotational force in a sealed container, and a hermetic rotary compressor or a hermetic scroll compressor that discharges refrigerant after being sucked in and compressed by the rotational force of the motor. Use the lubricating oil from the bottom of the closed container to lubricate the lubricating oil supply device at the friction part of the compressor parts with these hermetic compression tools. [0003] Take the scroll compressor as an example to illustrate the existing lubricating oil supply device for hermetic compressors as fo...
