Abstract

The invention discloses a modified oil filter which comprises a case. A filter cartridge is disposed in the case. An end cover is disposed above the case. A bypass valve is disposed between the filter cartridge and the end cover and is fixedly connected with the end cover through self-sealing screws. Magnetic steel is arranged between the filter cartridge and the bypass valve. One side of the case is provided with an oil inlet. The modified oil filter is characterized in that a dirt collection box is disposed on the lower portion of the filter cartridge, and the lower end of the dirt collection box is fixed on the case of the oil filter. The modified oil filter has the advantages that the modified oil filter is reasonable in structure, and a system is prevented from being re-polluted by filtered impurities.

Description

A kind of improved oil strainer
Technical field
The present invention relates to a kind of improved oil strainer.
Background technique
Modern project machinery and various jumboes have adopted Hydraulic Power Transmission System widely; in all kinds of Hydraulic Power Transmission Systems for reliable performance and working life of the various hydraulic element in effective protective system; mostly be provided with the various impurity of filter in coming the filtering oil tank liquid at the filler opening of hydraulic system and return opening, guarantee the clean degree of system's inner fluid.At present, the oil strain mode in the existing machinery Hydraulic Equipment is all to force fluid the flow through gap of filter core to reach filtering greater than the impurity particle of gap size.These impurity particles that are filtered off stick to cartridge surface; making it cross oily ability reduces gradually; and in case shut down; the pressure reduction of filter core inner and outer surface disappears; the larger particles of cartridge surface will drop to the oil purifier cylinder body bottom and be deposited on this, and when renew cartridge more, the impurity particle that is deposited on the oil purifier cylinder body bottom is not taken out of has on the contrary together been taken back fuel tank by the impulsion of the fluid of disturbance; again add systemic circulation, the wearing and tearing of each class component and Sealing in acceleration oil pump and system.Therefore, should provide a kind of new technological scheme to address the above problem.
Summary of the invention
The objective of the invention is: for above-mentioned deficiency, provide a kind of rational in infrastructure, guarantee that system's turbidity test can be by the improved oil strainer of the impurity recontamination of filtering.
For achieving the above object, the technical solution used in the present invention is: a kind of improved oil strainer, comprise housing, be provided with filter core in described housing, the top of described housing is provided with end cap, be provided with bypass valve between described filter core and end cap, described bypass valve is fixedly connected with by self-styled screw with end cap, is provided with magnet steel between described filter core and bypass valve, and a side of described housing is provided with filler opening, the bottom of described filter core is equipped with feculence box, and the lower end of described feculence box is fixed on the housing of oil strainer.
Further, described feculence box is installed and is fixed in the endoporus of filter core lower end.
a kind of improved oil strainer of the present invention, fluid flows into from the upper end endoporus of filter core, flow to after the filtration of filter core in the cavity volume that the cylindrical of filter core and housing endoporus form, then the diffusion aperture on housing flows to fuel tank, this moment, most of impurity particle was adsorbed in the internal surface of filter core by the pressure reduction between the filter core inside and outside circle, the heavier particle of minority falls after rise in the feculence box endoporus and is deposited on this, after filter core surpasses active duty cycle or the warning of alarm sender, when the user shuts down more renew cartridge, feculence box and all impurity particles have just been taken when taking out filter core out of.
Advantage of the present invention is: rational in infrastructure, guarantee that system's turbidity test can be by the impurity recontamination of filtering.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, housing, 2, filter core, 3, end cap, 4, bypass valve, 5, self-styled screw, 6, magnet steel, 7, filler opening, 8, feculence box.
Embodiment
As shown in Figure 1, a kind of improved oil strainer of the present invention, comprise housing 1, be provided with filter core 2 in housing 1, the top of housing 1 is provided with end cap 3, be provided with bypass valve 4 between filter core 2 and end cap 3, bypass valve 4 is fixedly connected with by self-styled screw 5 with end cap 3, is provided with magnet steel 6 between filter core 2 and bypass valve 4, and a side of housing 1 is provided with filler opening 7, the bottom of filter core 2 is equipped with feculence box 8, and the lower end of feculence box 8 is fixed on the housing 1 of oil strainer.
Feculence box 8 is installed and is fixed in the endoporus of filter core 2 lower ends.Advantage of the present invention is: rational in infrastructure, guarantee that system's turbidity test can be by the impurity recontamination of filtering.

Claims (2)

1. improved oil strainer, comprise housing, be provided with filter core in described housing, the top of described housing is provided with end cap, is provided with bypass valve between described filter core and end cap, and described bypass valve is fixedly connected with by self-styled screw with end cap, be provided with magnet steel between described filter core and bypass valve, one side of described housing is provided with filler opening, it is characterized in that: the bottom of described filter core is equipped with feculence box, and the lower end of described feculence box is fixed on the housing of oil strainer.
