When the hydraulic machine is moving, the motion component produces a sudden shock
The reverse valve opens too fast, and the flow and pressure surge, causing the moving parts to snap at first. In the design of the commutator valve, such as can make the valve core open change has a short buffer process, can reduce hydraulic shock very well.
Start-stop or reversing impact is too big, can pump pressure value is too high, the hydraulic pump outlet should be adjustable regulating valve, oil should also have a decompression alone or overflow vent valve adjustment.
There is no buffer for the solenoid valve core. There is also the unreasonable design of hydraulic oil. It doesn't seem to be right upstairs. There should be no movement or crawling.
