What is Hydraulic Filter Press?
The hydraulic opening and closing system will include one double-acting hydraulic cylinder and one hydraulic power pack. The system will be designed to automatically maintain the proper clamping force throughout the cycle.
The hydraulic power pack will consist of an electric motor is driven hydraulic pump, control valve, hydraulic pressure relief valve. Press closing pressure will be automatically controlled by pressure switches
There is two types of hydraulic filter press available in market
- Mechanical locknut type hydraulic closing device
- Double-acting motorized AUTO hydraulic closing device
In mechanical locknut type systems, require to tighten the lock nut & open the locknut manually at the time of opening & closing of the cylinder. Whereas in the motorized hydraulic system it is operated automatically only by selecting the forward/reverse switch.
Hydraulic filter press is more reliable than manual press as the hydraulic system itself holds the filtration pressure
In motorized hydraulic filter press, Ram of the cylinder is coupled with moving plate hence no extra manpower required for shifting the moving plate back to open the Filter press.
The motor of the power pack restarts and stops automatically at lower and upper pressure cut off.
