Abstract
The utility model relates to improvement of a hydraulic oil tank of a wheel loader, and provides the hydraulic oil tank for an oil return pipe mouth filter. The hydraulic oil tank comprises a rack and an oil tank body, wherein the oil tank body is provided with an oil filling pipe mouth, an oil return pipe mouth and an oil outlet pipe mouth, the oil filling pipe mouth and the oil outlet pipe mouth are respectively provided with an A-type filter, and a dustproof cap is added to a connecting oil pipe of the A-type filter on the oil filling pipe mouth. Particularly, a B-type filter is arranged on the oil return pipe mouth of the oil tank body and comprises a filter screen assembly, a connecting flange and a connecting oil pipe, wherein the aperture of the filter screen assembly is smaller than 12 micrometers. The hydraulic oil tank solves the problems that particle impurities exist in reflux hydraulic oil, a filter at an oil tank oil filling pipe mouth can not meet filtering requirements and abrasion and consumption of hydraulic system parts are large in the wheel loader in the prior art, and is mainly used for improvement for the hydraulic oil tank of the wheel loader.
Description
Technical field
The utility model relates to the improvement of wheel loader hydraulic oil container, is a kind of oil return mouth of pipe filter cleaner hydraulic oil container.
Background technique
Wheel loader is provided with the fuel feeding that hydraulic oil container is used for hydraulic system, prior art wheel loader hydraulic oil container is provided with filler neck, the fuel-displaced mouth of pipe and the oil return mouth of pipe, filler neck is for add hydraulic oil in fuel tank, the fuel-displaced mouth of pipe is to the hydraulic system fuel feeding by oil hydraulic pump, the oil return mouth of pipe is that relief valve for hydraulic system and oil hydraulic pump is to fuel tank reflux liquid force feed, be separately installed with filter cleaner on filler neck and the fuel-displaced mouth of pipe, the aperture of filter screen in the filter cleaner≤80 μ m; The problem that prior art wheel loader hydraulic oil container exists is: there are component wear particle foreign material in the reflux liquid force feed in the fuel tank, filter cleaner on the tank filler tube mouth does not satisfy the requirement of hydraulic pressure oil filtration, and the oil hydraulic pump in the wheel loader and hydraulic system parts cause component wear consumption large because of hydraulic oil particle foreign material more.
Summary of the invention
The purpose of this utility model is exactly will solve the existing fuel tank reflux liquid of existing wheel loader hydraulic oil container force feed to exist particle foreign material, tank filler tube mouth filter cleaner not to reach filtration requirement and the large problem of hydraulic system component wear consumption, and a kind of oil return mouth of pipe filter cleaner hydraulic oil container is provided.
Concrete scheme of the present utility model is: a kind of oil return mouth of pipe filter cleaner hydraulic oil container, it is provided with frame and fuel tank, be respectively equipped with filler neck, the oil return mouth of pipe and the fuel-displaced mouth of pipe on the fuel tank, A type filter cleaner all is installed on filler neck and the fuel-displaced mouth of pipe, wherein, add dust cap on the connected pipes of filler neck A type filter cleaner; It is characterized in that: on the oil return mouth of pipe of fuel tank the Type B filter cleaner is installed, the Type B filter cleaner is comprised of filter screen assembly, adpting flange and connected pipes, the aperture of filter screen in the filter screen assembly＜12 μ m.
The utility model is compared with existing wheel loader hydraulic oil container, the utility model is that the oil return mouth of pipe at hydraulic oil container adds the Type B filter cleaner, and the aperture of filter screen in the Type B filter cleaner＜12 μ m, then effectively the particle foreign material filtration of hydraulic system for wheel loader component wear is collected in the filter screen assembly of Type B filter cleaner, reflux liquid force feed in the hydraulic oil container can reach the requirement of hydraulic pressure oil filtration, and the parts that solved in the existing hydraulic system of original structure cause the large problem of component wear consumption because of hydraulic oil particle foreign material more; The utility model is simple in structure, effect is remarkable, the oil return filter precision high; The utility model preferably resolves the existing fuel tank reflux liquid of existing wheel loader hydraulic oil container force feed and exists particle foreign material, tank filler tube mouth filter cleaner not to reach filtration requirement and the large problem of hydraulic system component wear consumption.
