The speed of the hydraulic press is slow, 80% of the reason is the hydraulic oil problem (dirty, water, high temperature caused by viscous, etc.), 10% is the pump bad (such as no oil absorption, etc.) or valve (such as unloading valve leakage) bad problem, the rest 10% probability is the leakage of hydraulic cylinder (oil leakage from high pressure warehouse to low pressure warehouse when using) problem. It is suggested that the oil should be changed first, and the dirty oil in the hydraulic cylinder should be cleaned. If the problem is not solved, replace the original valve one by one with the standby valve and run the test to determine which valve is broken. If the problem is not solved, disassemble the cylinder to replace the sealing ring. Finally, I can't find a way. Change the pump.
