Solution to insufficient pressure of filter press

The reasons for the insufficient pressure of the filter press are the open-phase operation of the hydraulic pump motor of the filter press, the improper adjustment of the pressure regulating valve or the regulation failure. For these three reasons, you can take corresponding measures to solve them. Please follow Su Dong to learn together.


First, check whether the motor of the filter press is in good condition and whether it is running overheated. If the motor is damaged, check the wiring terminals, cables, thermal relays, contactors and other parts of the motor and the components themselves along the load circuit of the motor one by one, until the cause of the fault is found, the fault is eliminated and the damaged Motor. If no motor problems are found, consider whether the pressure regulating valve is intact.


The reasons for such failures caused by the failure of the pressure regulating valve: 1. Improper adjustment of the rated pressure of the pressure regulating valve; 2. The adjusting bolt is screwed too tightly or the vent is blocked by foreign matter or the product is improperly selected; 3. The seal is damaged and the seal is not properly sealed. Strictly, or there is foreign matter in the valve port and the valve.


The solution to the pressure shortage caused by the failure of the pressure regulating valve: 1. Adjust the regulating bolt of the pressure regulating valve (screw the bolt down to increase the working pressure); 2. Check whether the bolt is adjusted too tightly and dredge the valve body Oil drain hole; 3. Replace the oil drain valve seal or disassemble and replace the inlet and drain valve valves.


The above is the solution to the insufficient pressure of the filter press. Have you learned it? In the case of insufficient pressure, the filter press cannot work normally, which will affect the progress of the work process. In order to prevent insufficient pressure from affecting the normal operation of the filter press, everyone should pay attention to these problems in the usual inspections.
