First check if the motor of the filter is running normally, there is no hot operation. If the motor is damaged, the wiring and components of the motor terminal, the cable, the hot relay, the contactor, etc. should be checked one by one, until the failure is to find the failure and repair damage Motor. If the motor is not faulty, it should be considered to check if the pressure regulator is intact. The solution of the pressure regulating valve causes the problem of insufficient pressure is as follows: 1. Adjust the adjustment of the pressure regulator (bolted downward, the working pressure is increased); 2. Check whether the bolts are tightened, dredging valves Body drain hole; 3, replace the drain valve door seal or replace the oil, drainage valve sheet. The above is a solution to the pressure of the filter press, to check regularly, ensure the machine is working properly! When the pressure is insufficient, the filter machine will not work properly, affect the efficiency of the working process. In order to prevent pressure from being insufficient, it will affect the normal operation of the filter machine. Everyone should pay attention to these issues in the usual inspection.
