If your hydraulic press machine speed gets slowly,following are methods to solve it.

1. Air in the hydraulic cylinder

When the hydraulic press machine pressing speed gets slowly, we should first consider that air in the hydraulic cylinder, interrupt the corresponding exhaust operation through the exhaust equipment of the machine, and check whether there is air in the movement direction of the piston rod. If so, it may be If the sealing ring is defective, the sealing ring should be changed in time.

2.  Check whether the hydraulic pump is operating normally
When the hydraulic press machine moves slowly and the hydraulic pump runs irregularly, and sometimes it may be blocked or slightly seized, it means that there is a problem with the hydraulic pump and the hydraulic pump should be repaired or changed in time.

3. Check the operation of the piston
When the hydraulic cylinder of a hydraulic press machine with a buffer device is intermittently started in reverse, the piston will be temporarily interrupted or retreated, causing the hydraulic machine to move slowly. This is because the one-way valve orifice is too small, resulting in a small amount of hydraulic oil entering the buffer chamber of the machine. When this kind of defect occurs, the orifice of the one-way valve should be enlarged and the amount of oil entering the buffer chamber should be added.

4. High piston movement speed
When the piston movement speed is too high, the steel ball of the one-way valve will move, and then the orifice of the one-way valve will be blocked, causing irregularities in the movement of the hydraulic cylinder. When encountering this situation, the steel ball should be converted into a poppet valve spool with a pilot valve.

5. The hydraulic cylinder is not sensitive
When the inside of the rubber hose is peeled off, it will cause intermittent defects in the oil circuit, causing irregularities in the action of the hydraulic cylinder. Cleaning method: change the rubber hose in time.

The above are some of the reasons for the slow action of the hydraulic press machine and the corresponding solve methods.More hydraulic press machine solution details, please contact us [email protected] and [email protected] .
