Causes of electrical failure of filter press

         Since the use environment of the filter press is usually very harsh, it either contains a certain concentration of acid gas, or is full of kerosene, alkaline dust, etc. In the long run, these corrosive chemicals will accumulate and damage the electrical components of the filter. This may cause electrical failure and cause the control buttons to become unresponsive. Let’s talk about the solution to this problem:
When the control button operation of the filter press is invalid, please first check whether the structure and contacts of the control button of the filter press are normal. Inspection method: Press the corresponding button and observe whether the corresponding node indicator light of the PLC input terminal is on. If it is lit, it means that the button is not malfunctioning. If it is not lit, please check the button and related wiring.

When it is determined that there is no fault on the input side, continue to press the input button and observe whether the relevant indicator light on the PLC output terminal side is on. If any indicator lights are on, please check the intermediate relays, contactors and solenoid valve coils related to the output. If no indicator light is on, it means that the PLC does not meet the output conditions. Check whether the relevant limit switches and proximity switches are intact, whether the nodes are opened and closed correctly, to find out the cause of the fault, make a correct judgment, and solve it in time.
Regarding this issue, I would like to remind everyone that when buying a filter press, in addition to the product quality and function, the corrosion resistance of electrical components should also be considered, so as to prevent the electrical components from prematurely corroding the filter press. Using the machine will bring more unnecessary maintenance costs and troubles.
