Description
Technical field
The present invention relates to filter, especially a kind of coarse-fine integrated filter of hydraulic station suitable for being filtered to hydraulic oil
Device.
Background technique
Currently, the filter installed in hydraulic system, is all to be cascaded by thick liquid device and smart liquid device, to complete
Filtering to medium.This structure is requiring working media to use in high or more severe working environment hydraulic system, often
Need to working media carry out it is coarse-fine be filtered for multiple times, cause system repeatedly to replace filter core, if replacement it is improper also will cause leakage,
Shutdown maintenance, not only structure is complicated, take up a large area, is at high cost, working efficiency is low.
Summary of the invention
The object of the present invention is to provide it is a kind of it is compact-sized rationally, occupied area is small, work efficiency is high, maintenance cost is low
The coarse-fine integrated filter of hydraulic station.
The technical scheme of the invention is completed in the following manner, it includes a switching valve, uses in the side of switching valve
Screw rod and nut are fitted with the coarse filtration cylinder with coarse filter element, are provided in the other side of switching valve with screw rod and nut
Refined filtration core and refined filtration cylinder are equipped with oil inlet pipe between the oil inlet and coarse filter element of switching valve, in the oil outlet and essence of switching valve
It is equipped with oil outlet pipe between filter core, the conversion pipeline of connection coarse filter element and refined filtration core is equipped at the middle part of switching valve, in each filter cylinder
One side lower part is equipped with a signalling generator with screw respectively, a side lower part of each filter core be separately installed with one it is overhanging to filter cylinder
Blowdown plug out cooperates in the upper end of each filter cylinder screw 14 and upper cover 13, and upper lid is equipped with an expanding plug.
Coarse filtration and essence filtering of the invention is completed in a double filter cylinder equipment, and installs signalling generator on each filter cylinder,
With it is compact-sized rationally, occupied area it is small, filter efficiency height, greatly reduces production cost at a little repair.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is structural exploded view of the invention；
Fig. 3 is the bottom view of Fig. 1.
Specific embodiment
Embodiment is described in detail in conjunction with attached drawing, it includes a switching valve 7, in the side of switching valve screw rod 6 and nut 9
It is fitted with the coarse filtration cylinder 3 with coarse filter element 1, is provided with refined filtration core 12 in the other side of switching valve screw rod and nut
With refined filtration cylinder 11, between the oil inlet 10 and coarse filter element of switching valve be equipped with oil inlet pipe 10-1, switching valve oil outlet 8 with
It is equipped with oil outlet pipe 8-1 between refined filtration core, is equipped with the conversion pipeline 10-2 of connection coarse filter element and refined filtration core at the middle part of switching valve,
A signalling generator 4 is installed with screw 5 respectively in each one side lower part of filter cylinder, is separately installed with one in a side lower part of each filter core
The blowdown plug 2 stretched out to outside filter cylinder cooperates in the upper end of each filter cylinder screw 14 and upper cover 13, and upper lid is equipped with a deflation
Plug 15.
When work, unfiltered oil liquid enters coarse filtration cylinder through oil inlet pipe from switching valve top oil inlet, through coarse filter element mistake
The refined filtration cylinder for flowing into the other side after filter through intermediate conversion pipeline by lower part, by lower part oil outlet pipe stream after the filtering of refined filtration core essence
Enter hydraulic system.It is furnished with a signalling generator on each cartridge filter, the sending when filter core blocking pressure difference reaches signalling generator setting value
The filter cylinder of alarm, side of alarming shuts down replacement, unscrews expanding plug, opens upper cover after deflation pressure release, unscrews the discharge of blowdown plug
Pollutant cleans filter cylinder, replaces filter core, installs again, does not alarm and does not have to change.
