Abstract

The utility model discloses a mechanical loader driving oil filter and relates to a spare part of a fluid pressure system, the purpose of the utility model is to provide the mechanical loader driving oil filter whose filter element is conveniently folded and packed. The further purpose of the utility model is to provide the mechanical loader driving oil filter which is enabled to discharge contamination in the filter at any time. The technical solving scheme of the utility model is that an oil filter is driven by a mechanical loader, the utility model comprises shells and the filter element, wherein a liquid guiding core is arranged on the lower portion of an upper shell, an upper end plate and a lower end plate are seal-connected with the upper shell, two ends of a liquid guiding tube are seal-connected with holes which are evenly distributed along the circumference on the upper end plate and lower end plate of the liquid guiding core, a hole which is on the center of the lower end plate is seal-connected with the upper end of a tube, the lower end of the tube is seal-connected with a filtering element framework which is in a lower shell, and outer screw threads of an end cover are matched with inner screw threads of an upper shell port. The utility model is used for engineering automobiles.

Description

Loader transmission oil filter

Technical field:

The utility model relates to a kind of component of fluid-pressure system, particularly a kind of loader transmission oil filter.

Background technique:

The loader bending moment oil rectifier of the patent No. 20,052,003,252 1.1, solved filter cleaner in the past since on the filter block oil inlet and outlet be located at both sides and need oil pipe and disturb the homonymy of 180 ° curved and loader and pass in and out oil pipe and be connected, the oil pipe pipeline is long, complex process, the shortcoming that cost is high.This patented product is because filter block is to be connected with flange by pressing plate with filter housings, when renew cartridge more, need twist after several bolts make filter block and filter separates, renew cartridge more, inconvenient, in addition, this filter cleaner can not in use in time eject the dirt that filters out from filter cleaner.

Summary of the invention:

The purpose of this utility model provides a kind of folding dress filter core loader transmission oil filter easily.Further purpose of the present utility model provides a kind of can at any time the dirt in the filter being ejected.Technical solution of the present utility model is, loader transmission oil filter, comprise housing and filter core, it is characterized in that: a water conservancy diversion core places the bottom of upper shell, the upper and lower end plate and the upper shell of water conservancy diversion core are tightly connected, the hole of the two ends of honeycomb duct and the upper and lower end plate of water conservancy diversion core upper edge circumference uniform distribution is tightly connected, the center of lower end sheet has the upper end of a hole and a pipe to be tightly connected, frame of filter element in the lower end of this pipe and the lower shell body is tightly connected, and the internal thread of outside thread on the end cap and upper shell port matches.Bottom at lower shell body is provided with blowdown valve.Between water conservancy diversion core upper head plate and end cap, be provided with pressure spring.The utility model not only has folding dress convenience compared with the prior art and also has the advantage that the dirt in the filter is discharged easily.

Description of drawings:

Fig. 1 is the sectional arrangement drawing of the utility model loader bending moment oil strainer, and Fig. 2 is a water conservancy diversion core sectional arrangement drawing, and Fig. 3 is the A-A sectional view of Fig. 2.

Embodiment:

The utility model is described in further detail in conjunction with above accompanying drawing, lower shell body 1 and upper shell 5 are integrally welded, filter core places lower shell body, one side of upper shell is provided with into and out of hydraulic fluid port 9,10, water conservancy diversion core body 3 places the upper shell of filler opening below, and the ring surface of water conservancy diversion core body upper and lower end seals mutually with the upper shell internal surface of filler opening below.The structure of water conservancy diversion core body is, its two ends are a plectane, the periphery of plectane is provided with circular groove and seal ring matches, the two ends of 8 honeycomb ducts 6 respectively with upper and lower plectane on uniform 8 holes be tightly connected, the circular plate of upper end is except that not opening of 8 remaining parts the hole is arranged, porosely at the center of lower end circular plate be connected with a seal of tube, the lower end of pipe is connected (referring to Fig. 2 and Fig. 1) with the reinforced seal of filter core, when filter need be provided with Decompression valves, the center of the upper end circular plate of water conservancy diversion core body is a hole at this moment, and spherical Decompression valves (referring to Fig. 1) can be set in the hole.The outside thread that is provided with internal thread and end cap 8 at the upper end-hole place of upper shell matches, and end cap is provided with a hexahedron, is provided with stage clip 7 between the upper head plate of water conservancy diversion core body and end cap.At the lower end of upper shell welding a plate, establish the bolt via hole on it, this connecting plate is used for filter and is connected with loader.Bottom at lower shell body is provided with valve, is used for dirt in the discharge filter.

The work principle of filter of this filter is, transmission oil enters from the filler opening of upper shell, in lower shell body, behind the strainer filtering of filter core, enter oil pipe from oil outlet through 8 water conservancy diversion pores of water conservancy diversion core body by the cavity that the inner chamber of filter core is passed through outside 8 diversion tubes of the pore of water conservancy diversion core body lower end and water conservancy diversion core body from cavity between filter core and the lower shell body.When needs more during renew cartridge, method of its dismounting filter core is, after blocking six sides on the cover plate cover plate is spun down from upper shell with spanner, after the water conservancy diversion core body being released, can take out filter core again, and is very convenient.

Claims
