Why The Hydraulic press Machine Falling Too Slowly?
What is the reason why the hydraulic press machine falling too slowly? The first reason that comes to mind is the problem of hydraulic oil. Dirty oil has impurities and has not been replaced in time. Then the pump is broken and cannot absorb oil, or the valve unloading valve leaks oil. These faults may cause the sliding speed to be slow. When the hydraulic cylinder leaks oil, there is a problem with the oil leaking from the high pressure tank to the low pressure tank.
It is recommended to change the oil first and drain the dirty oil in the hydraulic cylinder. If the problem is still not resolved, replace the original valve one by one with the spare valve and test to find the faulty valve. If the problem has not been solved, remove the seal of the cylinder, the ring pump that all the above investigations have not solved.
The solution is to observe which element leaks oil if the oil return line leaks. Remove relief valve and clean; test or replace spring to restore its working performance. Then check if the relief valve is working properly.
If not, remove the relevant valve parts for cleaning, and check the size of the sealing gap and various sealing devices.
If the sealing device is damaged, it should be replaced in time, check the output flow of the hydraulic pump, measure the volumetric efficiency of the hydraulic pump to determine whether the pump can continue to be used, and repair or replace the severely worn parts.
