1. Installed at the pump’s suction port: A surface-type oil filter is typically installed in the hydraulic pump’s suction line, primarily to intercept large-sized contaminant particles and thereby protect the hydraulic pump from damage. Additionally, the filter’s capacity must ensure a flow rate of at least twice the pump’s rated flow, while the pressure drop should be kept within 0.02 MPa.

It is embodied in three core dimensions: the implementation of predictive maintenance, the acceleration of product design iteration, and the construction of intelligent operation and maintenance systems, driving the industry to transform from passive replacement to active optimization.

Firstly, the welding of metal sintered filter elements is one of the most crucial steps in their manufacturing process, as it directly affects the filtration performance and service life of the filter elements. During the welding process, high-precision welding techniques must be employed to ensure the roundness and aesthetic appearance of the weld seams, thereby guaranteeing the integrity and stability of the filter elements.

The end cap, as an important component of the filter element, is usually made by stamping or machining processes, and the materials include stainless steel, carbon steel, aluminum and other metals. Its design features include a certain depth of glue injection groove to ensure sealing performance. In addition, the radial end cap is specially equipped with an O-ring groove to further enhance its sealing effect.
