Abstract

The utility model discloses a detachable metal mesh filter core and the improvement is characterized in that two ends of at least one metal mesh filtering cylinder core 2 are respectively and moveably ring-sleeved and connected with a end cap 1. The filtering cylinder core in the metal mesh structure is arranged in the inner chamber of the filter to bear the pressure caused by pumped machine oil without deformation and the good filtering effect of the machine oil is provided with reducing the abrasion of machine parts of an engine. Through disassembling the end caps arranged on two ends of the metal mesh filtering cylinder core, separating parts are also capable of being cleaned and repeatedly used, thereby extending the service life and lowering the use-cost of users.

Description

Detachable wire netting filter element

The utility model relates to motor oil delivery filter parts; Be specifically related to the detachable wire netting filter element of motor input machine oil.

In the prior art, the filter element of motor input machine oil normally is folded into multilayer by filter paper and repeats tortuous circular filter core cartridge, is fixed with end cap at its two ends and constitutes.Exist not enough: the one, the machine oil poor filtration effect has increased the weight of the component wear of motor.Because of placing the machine oil of filter housing intracoelomic cavity for a long time, soaks the papery filter core cartridge, the distortion of easily feeling like jelly, especially under the situation that machine oil is thicker when the motor starting cold, it is big that the papery filter core cartridge filters thick shape machine oil resistance, easily making multilayer folding on the papery filter core cartridge cylindrical repeat the tortuous serious extrusion-deformation of filter paper is sticked together, influenced smooth output after the filtration of machine oil, the engine oil pressure that causes the filter box intracoelomic cavity to pump into constantly raises, when engine oil pressure is elevated to certain value, the bypass valve of filter cleaner inner chamber is opened automatically, make the machine oil that does not obtain filtering enter surface of the work to be lubricated in the motor, cause motor parts premature wear through the main oil pipe road.Two are to use the life-span short, the cost height.Job requirement according to motor, general filter element work 220 hours-250 hours, because of the grease on its filter element stops up, influenced the quality that machine oil filters, can use after needing to clean, because of the papery filter core cartridge can't clean, people can only regularly discard and renew, and have increased user's user cost.

The purpose of this utility model is: a kind of good filtration effect is provided, alleviates motor component wear and repeated washing use easily, increase the service life, reduce the detachable wire netting filter element of customer using cost.

The technical solution of the utility model is achieved in that this detachable wire netting filter element, comprises end cap; Improvement is: at the two ends of layer of metal net filtration tube core, the loose collar cover is connected with end cap respectively at least.

The utility model adopts said structure, because the filter core cartridge of metal mesh structure places the filter cleaner inner chamber, it is indeformable to bear the engine oil pressure that pumps into, and the machine oil good filtration effect has alleviated the motor machine members.Metal mesh filter tube two ends loose collar cover is connected with end cap, when the grease of metal mesh filter tube core generation stops up, can dismantle the end cap at metal mesh filter tube core two ends easily, bulk-breaking cleans, reusable, prolong the working life of wire netting filter element, reduced user's user cost.

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
