What should I do if the Hydraulic System of the sludge Filter Press fails?

1. The oil pipe joint leaks oil

Restricted by the working environment and use time, after a period of use, the oil pipes and joints will age and cause oil leakage. Just replace the corresponding oil pipe.
2. The low-pressure and high-pressure pumps do not work
The Filter press cannot realize the closing and opening functions. Check the oil pump motor and its corresponding circuit module, and replace the damaged parts.
3. The Plate And Frame Filter Press cannot maintain pressure and cannot complete the closure
Failure to maintain pressure in the hydraulic system is often caused by the failure of the one-way valve, and the Plate and Frame Filter Press is no exception. At this time, it is necessary to check the one-way valve on the main oil cylinder of the machine head and replace the damaged one-way valve.
4. The solenoid valve does not work, the reversing valve is blocked or worn and does not work.Just replace the corresponding valve group.
5. The hydraulic cylinder has crawling, noise, and piston wear
It may be caused by the air entering the hydraulic pipeline, or it may be caused by the newly replaced oil cylinder and the seal ring being too tightly matched, resulting in excessive friction. For the phenomenon of air intake, if there is no deflation device, the air can be forced out.
For excessive friction, apply lubricant to the main oil cylinder. The surface of the plunger is modified by chrome coating. Due to long-term bare leakage of the main oil cylinder plunger, it is eroded by flushing water, the surface is easy to rust, the sealing surface is uneven, the sealing effect is poor, and oil leakage is easy. Chromium treatment can resist water corrosion.
6. The hydraulic motor does not work
The internal gears of the hydraulic motor are worn or the teeth are broken, causing the motor not to work. Just replace the hydraulic motor.
7. Oil leakage at the joint of the valve block

Replace the corresponding o-ring and the corresponding oil pump. Replace the corresponding solenoid valve and clean the oil flow hole of the reversing valve. If the cylinder is worn, replace the master cylinder. Check the planetary gears in the hydraulic motor and replace worn gears or hydraulic motors. Replace the sealing ring.
