What about the failure of the Hydraulic System of the sludge Filter Press?

The hydraulic system is a very important part of the sludge Pressure Filter Equipment, but there are often problems, today I give you a summary of:

1.Oil pipe joint leaks oil
Restricted by the working environment and use time, after using for a period of time, oil pipes and joints will be aged and then leak oil. Replace the corresponding oil pipe.
2.Low pressure and high pressure pumps do not work
The Filter Press Machine cannot realize the function of closing and opening. Check the oil pump motor and its corresponding circuit module, and replace the damaged parts.
3.Plate And Frame Filter Press does not hold pressure and cannot complete closure
The hydraulic system does not hold pressure is often caused by the failure of the check valve, and the Plate And Frame Filter Presses is no exception. At this time, check the check valve on the main cylinder of the head, replace the damaged check valve.
4.the solenoid valve does not act, the reversing valve blockage or wear does not work
Replace the corresponding valve set.
5.the hydraulic cylinder has crawling, noise, piston wear
May be caused by the hydraulic pipe into the air, or may be the new replacement cylinder and seal with too tight, too much friction caused by. For the phenomenon of air intake, if there is no exhaust device, you can forcibly discharge the air.
For the phenomenon of excessive friction, lubricant can be applied to the master cylinder. Plunger surface chrome coating modification. As the master cylinder plunger is exposed for a long time and eroded by flushing water, the surface is easy to rust, the sealing surface is uneven, the sealing effect is poor, and it is easy to leak oil. Chromium treatment can resist water corrosion.
6.Hydraulic motor does not work
Hydraulic motor internal gear wear or gear teeth fracture, resulting in the motor does not work. Replace the hydraulic motor.
7.Oil leakage at the valve block joint
Replace the corresponding o-ring and the corresponding oil pump. Replace the corresponding solenoid valve and clean the oil hole of the reversing valve. If the cylinder is worn, replace the main cylinder. Check the planetary gear in the hydraulic motor and replace the worn gear or hydraulic motor. Replace the seal.
