Hot press hydraulic cylinder operation can not drive the load
Nov 10, 2017

The first performance for the piston rod parking ban, thrust speed and operation, lack of stability and the reason is the internal leakage of hydraulic cylinder. The internal leakage of hydraulic cylinder hydraulic cylinder seal, including piston rod and the sealing cover seal and piston seal wear are excessive in leakage. The piston rod and the sealing cover is sealed leak reason, seal wrinkle, kneading, tear, abrasion, aging, transformation and deformation, the moment should replace the new seal. The primary reason for excessive wear of piston seal is improper regulation of speed control valve, resulting in excessive back pressure and improper sealing device or hydraulic oil pollution. The second is the foreign material entering into the device and the quality of the sealing material is not good.
