How is the top cylinder of the hydraulic press not returned

As we all know, the hydraulic press will inevitably have some failures due to some external factors when working. Only by understanding the cause of the failure can we solve the problem in time.

Now Dongguan Keheavy Machinery Technology Co., Ltd. tell you how the hydraulic press does not return the top cylinder when working and how to deal with it.

Problem 1: The hydraulic press ejecter cylinder does not return the solenoid valve is stuck or the plug is not flexible, and the coil is burned out.

Treatment method: Check whether the electromagnet is flexible, whether the plug is loose, and whether the coil is damaged.

Problem 2: The oil discharge plug-in of the ejector cylinder rod cavity of the hydraulic press is stuck or the plug-in controls the pilot relief valve pressure is too low.

Treatment method: Check whether the main spool of the ejector cylinder rod cavity oil discharge plug-in is stuck, take out the spool and clean it before installing it, check whether the plug-in relief valve is stuck or whether the regulating pressure is too low.

Problem 3: The suction area is stuck.

Solution: Check whether the spool is stuck.
