A hydraulic filter element for a filter includes an end cap, a central tube, origami and clip strips, an origami is arranged between the central tube and clip strip, the end cap includes an upper end cap and a lower end cap, the upper end cap and the lower end cap The covers are connected by origami, the outer side of the origami is provided with a clamping strip, the origami and the central tube are cylindrical, and the axial direction of the central tube is the same as that of the origami and the hydraulic filter element. This kind of hydraulic filter element adopts hydraulic filter paper for origami. The paper filter element has high cleaning efficiency, long service life and cheaper price than ceramic filter element, which reduces the production cost of hydraulic filter element, improves the filtration efficiency of hydraulic filter element and prolongs the service life of hydraulic filter element. , worthy of promotion.

Reduce the production cost of hydraulic filter elements

Hydraulic filter elements are used in hydraulic systems to filter out particulate debris and rubber impurities in the system, to ensure the cleanliness of the hydraulic system, to protect specific components in the hydraulic system, and to be installed upstream of the components to be protected in the medium pressure pipeline , in order to filter out the solid particles and colloidal substances in the working medium, effectively control the pollution degree of the working medium, and make the components work normally. The current hydraulic filter elements on the market have the following problems:

1. The production cost is high;

2. Short service life;

3. The filtering effect is poor and it is inconvenient to replace;

4. The appearance is not beautiful enough.

In order to solve the above technical problems, the following technical solutions are provided:

The hydraulic filter element used for the filter includes an end cap, a central tube, origami and clip strips. The origami is arranged between the central tube and the clip strip. The end cap includes an upper end cap and a lower end cap. The two are connected by origami, the outer side of the origami is provided with a clamping strip, the origami and the central tube are cylindrical, and the axial direction of the central tube is the same as the axial direction of the origami and the hydraulic filter element.

The connection between the upper and lower end caps and the origami is provided with a single-component curing glue, the upper and lower end caps are arranged in a circle, and the upper end cap is provided with an opening concentric with the upper end cap, and Its size is the same as that of the end face of the central tube.

The central tube, the upper end cap and the lower end cap are all made of electrolytic galvanized steel.

The origami is made of hydraulic filter paper material, and the folding distance along the circumference of the origami should be evenly distributed.

The clips are made of electroplated tin steel strips, and the clips are arranged inwardly.

The central tube is densely and uniformly provided with through holes.

The beneficial effects that can be achieved are: the hydraulic filter element used for the filter can effectively improve the hydraulic filter element through the origami provided on the outer side of the central tube between the upper end cover and the lower end cover, and the origami is made of hydraulic filter paper material. High filtration efficiency, low cost and easy replacement. By using electrolytic galvanized steel material for the upper end cover, lower end cover and center pipe, the acid resistance, rust resistance and corrosion resistance of the hydraulic filter element can be effectively improved, and the performance of the hydraulic filter element can be prolonged. It has a long service life and has a beautiful appearance. The joints between the upper end cover and the lower end cover and the origami are provided with one-component curing glue, which has strong corrosion resistance. The clip is made of electroplated tin steel strip. The material has the advantages of corrosion resistance, discoloration resistance, non-toxicity, easy brazing, softness, low melting point and good ductility, which can prolong the service life.
