What's the matter with the slow oil return of the single-column hydraulic press

When operating a single-column hydraulic press, the no-load oil return is slow. It is recommended to check whether the set pressure of the pressure regulating valve meets the requirements. Secondly, there are two reasons. First, there is a problem with the control parts in the hydraulic system, that is, the oil return valve. The valve core is stuck inside, take it out and clean it.

Second, the rubber ring in the cylinder may be rotten. Some hydraulic presses are designed with Y-shaped rubber rings, which means that the up and down movement is sealed separately. It is possible that the sealing ring on the return trip is rotten. It is best to disassemble the cylinder and check it.
