Technical Field

The invention relates to an automobile accessory, in particular to a hydraulic oil impurity removal filter.

Background

The fuel filter is an important part of internal combustion engine power equipment for vehicles, engineering machinery, ships and the like, is mainly used for filtering impurities in fuel oil, prevents the impurities in the fuel oil from entering the internal combustion engine, plays a role in protection, limitedly protects the safety of the internal combustion engine, and prolongs the service life of the internal combustion engine. Along with the development direction of compact structure, small volume, light weight and low energy consumption of the internal combustion engine, the fuel filter also needs to have the characteristics of small volume, strong reliability and beautiful appearance. However, in the prior art, the sealing manner between the cylinder body and the cylinder cover of the fuel filter is generally sealed by using a sealant. Although the sealant can ensure the sealing performance between the cylinder body and the cylinder cover, in the actual operation process, the sealing performance is poor due to the fact that the glue application amount and the glue application position are difficult to control, the rejection rate of the fuel filter is high, material waste is caused, the production efficiency is reduced, and the production cost is increased.

Disclosure of Invention

The invention provides the hydraulic oil impurity removal filter which is simple in structure, low in production cost, long in service life, good in fuel oil filtering effect, convenient to install, high in overall strength and capable of prolonging the durability.

The technical scheme of the invention is as follows: the filter comprises a sealing ring, a sealing ring fixing plate, a filter element front end cover, a filter element, a bypass valve, a filter element rear end cover, a top spring, a shell, a filter tube, a check valve and a threaded cover plate, wherein the sealing ring mounting plate is positively provided with a groove for placing the sealing ring, the filter element is arranged in the shell, the filter element front end cover and the filter element rear end cover are arranged at two ends of the filter element, the filter element rear end cover is internally provided with the top spring, the filter tube is arranged inside the filter element, the filter tube is provided with a plurality of through holes, the filter element is an activated carbon composite non-woven fabric layer, the bypass valve is arranged at the inner side of the filter tube, the check valve is arranged between the sealing ring fixing plate and the filter element front end cover, the filter tube is a hollow circular tube, the filter tube is provided with a, three rows are a group, a pair of reinforcing ribs is arranged on two sides of each group of circular meshes, and the reinforcing ribs protrude out of the surface of the filter pipe and are higher than the filter screen.

The invention has the advantages of simple structure, low production cost, long service life, good fuel oil filtering effect, convenient installation, high integral strength and prolonged durability.
