Description

Disassembly-free washable truck air filter assembly

Technical Field

The utility model belongs to the technical field of auto-parts, especially, relate to an exempt from to dismantle and can wash empty assembly of straining of truck.

Background

According to the filtering principle, the air filter can be divided into a filtering type, a centrifugal type, an oil bath type and a composite type. The air filters commonly used in the engine mainly comprise an inertia oil bath type air filter, a paper dry type air filter, a polyurethane filter element air filter and the like. The inertial oil bath type air filter is subjected to three-level filtration of inertial filtration, oil bath filtration and filtration, and the two latter air filters are mainly subjected to filtration by filter elements. The inertial oil bath type air filter has the advantages of small air intake resistance, adaptability to dusty and sandy working environment, long service life and the like, and is used on engines of automobiles and tractors with various models in the past. However, the air filter has low filtering efficiency, heavy weight, high cost and inconvenient maintenance, and is gradually eliminated in automobile engines. The filter element of the paper dry-type air filter is made of microporous filter paper treated by resin, the filter paper is porous, loose and folded, has certain mechanical strength and water resistance, has the advantages of high filtering efficiency, simple structure, light weight, low cost, convenient maintenance and the like, and is the most widely applied automobile air filter at present. The filter element of the polyurethane filter element air filter is made of soft, porous and spongy polyurethane, and has strong adsorption capacity, and the air filter has the advantages of a paper dry air filter, but has low mechanical strength and is widely used in car engines. The latter two air cleaners suffer from a short service life and unreliable operation under harsh environmental conditions.

When the filter is installed, no matter the air filter and the engine air inlet pipe are connected by adopting a flange and a rubber pipe or are directly connected, the air filter and the engine air inlet pipe are strict and reliable to prevent air leakage, and rubber gaskets are required to be installed on two end faces of the filter element; the wing nut that fixes the air cleaner housing cannot be over tightened to avoid crushing the paper filter element.

During maintenance, the paper filter element can not be cleaned in oil, otherwise the paper filter element can be failed, and a runaway accident is easily caused. During maintenance, only the vibration method, the soft brush method (brushing along the corrugation) or the compressed air blowback method can be used for removing the dust and dirt attached to the surface of the paper filter element. The coarse filter part is required to remove dust at the dust collecting part, the blade, the cyclone tube and the like in time. Even if the filter core can be carefully maintained each time, the original performance of the paper filter core cannot be completely recovered, and the air inlet resistance of the paper filter core is increased, so that the paper filter core is replaced by a new filter core when the paper filter core needs to be maintained for 4 th time. If the paper filter element has the problems of breakage, perforation or degumming of the filter paper and the end cover, the filter element is required to be replaced immediately.

When the filter element air filter is used, the filter element air filter is required to be strictly prevented from being wetted by rainwater, and once a paper core adsorbs a large amount of moisture, air inlet resistance is greatly increased, and the service life is shortened. In addition, the paper core air cleaner cannot come into contact with oil and fire.

To sum up, the filter core is dismantled trouble at installation and abluent in-process in the air cleaner assembly at present, and the in-process that works at air cleaner increases the loss to the truck engine simultaneously, and the oil consumption is big, and when dust, the dust in the clearance filter core, the clearance is unclean simultaneously.
