Problems solved by technology

Most of the current filters use a single-piece filter. The filter is too fine and the filtration flow is small, which cannot meet the large-capacity hydraulic system; there is also a single-piece filter with a single pore size. If the pore size is too small, the filter is easy to block. If the aperture is too large, small impurities can easily enter the hydraulic system, damage the hydraulic components, and affect the normal operation of the system

Embodiment Construction

[0012] Such as figure 1 As shown, a filter includes a cylindrical filter body 1, a filter element 2 and a cylindrical filter screen 3. A liquid outlet 4 is provided at one end of the filter body 1, and the outer side of the liquid outlet 4 is provided There is an interface 5 connected with the hydraulic system pipeline. The other end of the filter body 1 is fixedly connected to the filter element 2. A filter cavity 6 is reserved between the filter body 1 and the filter element 2, and a liquid inlet 7 is provided on the filter element 2. One end of the filter screen 3 is fixedly connected with the filter element 2, and the other end of the filter screen 3 is placed in the filter cavity 6, and the outer diameter of the filter screen 3 matches the inner diameter of the filter cavity 6, and is placed in the filter cavity The end of the filter screen 3 of 6 is in contact with the filter body 1, and the contact is provided with a sealing ring 9, so that the filter screen 3 directly c...

Abstract

The invention relates to a filter, which comprises a cylindrical filter body, a filter element and a filter screen, wherein a liquid outlet is formed at one end of the filter body; an interface connected with a hydraulic system pipeline is formed on the outer side of the liquid outlet; the other end of the filter body is fixedly connected with the filter element; a filtering cavity is formed between the filter body and the filter element; a liquid inlet is formed on the filter element; the filter screen is of a cylindrical structure; and one end of the filter screen is fixedly connected with the filter element. The filter is characterized in that: the other end of the filter screen is arranged in the filtering cavity; the outer diameter of the filter screen is matched with the inner diameter of the filtering cavity; and a plurality of filtering sheets are arranged on the cylindrical filter screen. The filter has the advantages of high filtering precision, high liquid flow rate, long service life and low manufacturing cost.

Description

Technical field [0001] The invention relates to a filter. Background technique [0002] The filter is a very important component in the hydraulic system. It is used to keep the hydraulic system clean and prevent impurities from entering the fluid supply system. It can ensure the normal operation of the hydraulic components and the system. Most of the current filters use single-piece filters, which are too fine and have a small filtration flow, which cannot meet the requirements of large-capacity hydraulic systems. There are also single-piece filters with a single pore size. If the pore size is too small, the filter is easy to block. If the aperture is too large, smaller impurities can easily enter the hydraulic system, damage the hydraulic components, and affect the normal operation of the system. Summary of the invention [0003] The purpose of the present invention is to provide a filter with high filtering precision, large flow rate and long service life. [0004] The technical...
