a filter element

Abstract

The invention discloses a cleaner filter core, which comprises an upper end cover, a lower end cover and a paper core, the paper core is arranged between the upper end cover and the lower end cover, and the paper core is sleeved on the outer wall of a center pipe, glass fiber wire is wound on the lateral wall of the paper core, and the glass fiber wire is bonded on the lateral wall of the paper core by a thermosol. The glass fiber wire is wound on the surface of the paper core y a coil winding machine, technology is simple, making is convenient, control is easy, the product appearance is beautiful, and the glass fiber wire is fine, compared with rubber ring having width being more than 10mm in prior art, practical filtering area of the filter paper can not be influenced, filtering efficiency and filtering quality of the filter core are increased, glass fiber wire and thermosol have machine oil and high temperature-resistance characteristics, the filter core is immersed in machine oil at high temperature for long term, the glass fiber wire and thermosol can not shed, and can not be dissolved in machine oil so as to pollute the machine oil.

Description

technical field [0001] The invention relates to a filter element. Background technique [0002] Most of the traditional filter element structure is: the valve seat and the end cover are integrated, and the center tube is a hollow cylinder. The advantage is that the injection mold structure is relatively simple, and the production of plastic parts is relatively easy, but the main disadvantage of this structure is: In the process of connecting with the filter paper, the end cover needs to be heated and baked. Since the boss of the valve seat is located on the side where the end cover is connected to the filter paper, the valve seat is easily deformed during heating and baking, which affects the assembly of the valve core and the valve seat. This will affect the filtering effect of the filter element. Contents of the invention [0003] The problem to be solved by the present invention is to provide a filter element to avoid deformation of the valve seat due to baking during ...
