Inside compressor, refrigerator system channel interior can not possibly be completely clean, and in operation process, impurity can be with freezing
Machine oil is back in the oil sump of compressor housing bottom.Existing oil pumping system of compressor, or without filter, or filter
Device is fixed.Compressor without filter, impurity is free movement.When compressor turns back on work, fuel sucking pipe
（Oil pump）Agitation oil sump, impurity is slowly stirred after coming, and may be sucked by fuel sucking pipe, is up transported to the friction pair of movement parts
Between, produce obvious negative effect：Frictional resistance increases, abrasion increase, or even stuck.Influence compressor performance and the life-span.
There is the compressor of fixed filter unit, then in any working condition of compressor, all lubricating oil is filtered.Have
The prior art of fixed filter unit includes：One fixed screen pack is installed in fuel sucking pipe uropore；Or in fuel sucking pipe
Outside sets a filter mantle for fence type.
These filters are all fixed, have certain flow resistance to the flowing of lubricating oil.Compressor start
In the stage, be drying regime between movement parts, needs badly and is lubricated, it is to avoid the heavy wear of start-up period.And compressor starting rank
Section rotating speed is slow, it is necessary to step up.During this, the pumping ability of fuel sucking pipe is not most strong, and fuel feeding is insufficient.If one
The filter of individual fixation carries out impurity screening, then the flowing of lubricating oil is necessarily hindered, produces certain flow resistance,
It is unfavorable for the fuel feeding of starting stage.Influence the service life of compressor.
