[0002] The hydraulic pump station outlet filter element is one of the key filtration components in a hydraulic system. It is used to filter impurities in the hydraulic oil, ensuring the normal operation of the hydraulic system and extending the service life of the equipment. A hydraulic pump station typically includes a hydraulic pump, oil tank, pipelines, and filtration system, while the outlet filter element is located in the oil circuit of the hydraulic pump station and is usually installed at the pump station outlet.

[0003] Since the hydraulic pump outlet filter element needs to be replaced after a period of use, conventional replacement structures make replacement difficult because the filter element is located inside the hydraulic pump. To address this problem, the inventors have proposed a quick replacement structure for the hydraulic pump station outlet filter element. Utility Model Content

[0004] To address the problem of difficult filter replacement due to the filter element being located inside the hydraulic pump in conventional replacement structures, this invention aims to provide a quick-replacement structure for the oil outlet filter element of a hydraulic pump station. By designing a replacement protrusion, the pleated filter screen can be easily removed during filter element replacement. The protrusion is usually located on the outside of the filter element, forming a prominent protrusion that helps operators remove the filter element from the filter element holder more easily by hand or with tools. Furthermore, by designing the filter sleeve cover as an embedded type, the sealing between the filter element and the filter element holder is effectively enhanced.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a quick-replacement structure for an oil outlet filter element of a hydraulic pump station, comprising a filter sleeve cover and a filter sleeve body. An oil tank wall is fixedly installed on the outside of the filter sleeve body. A first fitting groove is formed on the outside of the oil tank wall.

A magnetic filter sleeve 8 is fixedly installed inside the pleated filter screen 5. The magnetic filter sleeve 8 fits against the inside of the filter sleeve body 2.

[0024] The filter sleeve body 2 is fixedly installed with an oil inlet pipe 4, the pleated filter screen 5 is fixedly installed with a magnetic filter sleeve 8, the magnetic filter sleeve 8 is in contact with the oil inlet pipe 4, the filter sleeve cover 1 is provided with a polygonal rotating groove 10, the pleated filter screen 5 is fixedly installed with a lower filter screen limiting ring 7, the lower filter screen limiting ring 7 is in contact with the magnetic filter sleeve 8.

[0025] By adopting the above technical solution, the lower filter screen limiting ring 7 is attached to the magnetic filter sleeve 8, and the magnetic filter sleeve 8 can be used to adsorb iron filings in the hydraulic pump oil.

[0026] The upper filter screen 5 is fixedly installed with an upper filter screen limiting ring 6. The upper filter screen limiting ring 6 is fixedly installed with a replacement protrusion 18. The upper filter screen limiting ring 6 has a second fitting groove 19. The filter cover 1 is fixedly installed with a first spring 13. The end of the first spring 13 away from the filter cover 1 is fixedly installed with a compression ring 14. The compression ring 14 can fit into the second fitting groove 19.

[0027] By adopting the above technical solution, the extrusion ring 14 can be fitted into the second fitting groove 19.
