Hydraulic

A hydraulic system consists of five components: power elements, actuators, control elements, auxiliary elements, and the working fluid. The manufacturing quality of the parts in the core components of a hydraulic system—such as pumps, valves, cylinders, and piping—including critical geometric dimensional accuracy, surface profile, waviness, and surface roughness, has a decisive impact on system performance.

Valve spool and valve sleeve

The spool and sleeve are the core control components of a hydraulic system, and their mating precision directly determines the system’s sealing performance, response speed, and operational reliability. In high-pressure, high-frequency, or high-precision hydraulic applications, geometric deviations at the micron level can cause a drastic decline in system performance or even system failure. By precisely measuring their mating clearances and geometric tolerances (such as roundness and concentricit
