Abstract

An oil filter mechanism comprises an oil filter head (1), an O-shaped ring (2), an O-shaped ring (3), a support network (4), and a filter screen (5), adopts a filtering mode of 'inside-inlet outside-outlet', and allows the filtered impurities to be deposited in an oil filter cylinder. Compared with the prior art, the invention has the following active effect: because the filtered impurities are deposited in the oil filter cylinder, the mechanism is convenient for cleaning and replacement; when the oil pressure is high, the oil filter cylinder expands outwards, and thus is not compressed to deform or even collapse.

Description

A kind of oil filter mechanism
Technical field
The present invention relates to a kind of oil filter mechanism, relate in particular to a kind of oil filter mechanism that is used for helical-lobe compressor.
Background technique
In the helical-lobe compressor, need to rely on oil filter filtering well cuts to guarantee the cleaning of oil; At present, it is the filter type of " going out in advancing outward " that the oil filter of using on the helical-lobe compressor adopted more, and this makes the impurity that leaches be in the periphery of filter cleaner, can bring inconvenience to cleaning, changing; The oily filter cylinder that " advances formula outward " can be extruded distortion when pressure is big in addition, even shrivels.
Summary of the invention
The object of the present invention is to provide a kind of novel oil filter mechanism, its design orientation is: eliminate or alleviate the defective and the deficiency of above-mentioned existing mechanism by the pass-through mode that changes machine oil, guarantee the normal filtration of machine oil, maintain easily.
Purpose of the present invention can reach by following measure: a kind of oil filter mechanism, 1. it comprise oily filter, O type circle 2., O type circle 3., supporting network 4., 5. filter screen adopts the filter type of " in advance to go out ", the impurity that leaches retains in the oily filter cylinder.
The present invention can produce following good effect compared with the prior art: because the impurity that leaches can retain in the oily filter cylinder, it is convenient to clean, change; The oil filter cylinder was outside expansion when oil pressure was big, and can not be extruded distortion even shrivel.
Description of drawings
Accompanying drawing is the sectional view of oil filter of the present invention mechanism.
Embodiment
Below in conjunction with accompanying drawing specific embodiments of the present invention is elaborated:
Embodiment: a kind of oil filter mechanism (referring to figure), 1. it comprise oily filter, O type circle 2., O type circle 3., supporting network 4., filter screen 5., oily filter 1. locate peripheral by O type circle 2., 3. O type circle seal, 6. machine oil slave oil-in is located to enter in the oily filter cylinder, is 7. discharged by the machine oil outlet after 5. filter screen filters.

Claims (2)

1. an oil filter mechanism is tubular structure, in supporting network is arranged, filter screen;
2. a kind of oil filter as claimed in claim 1 mechanism is characterized in that: adopt the filter type of " in advance to go out ", promptly machine oil leaches outside the tube after entering in the oily filter cylinder by inlet, and impurity is stayed in tube.
