Design and research of steady-state flow force test bed for slide valve

This paper designs a test bed for steady-state flow force testing of slide valves. The test bed encompasses a hydraulic system, a primary control system, and a measurement and control system. The innovative aspect of this testing methodology lies in its capacity to mitigate the influences of friction, radial clamping force, and viscosity resistance through the reciprocating motion of the spool, thereby enhancing the precision of steady-state flow force testing. This test method can be used not only for product development and design but also for product manufacturing because it does not require the destruction of the spool and valve end covers.
