In general, when the plating solution is filtered, since the plating solution contains a trace amount of organic matter, it is easy to contaminate the liquid. It is customary to use powdered activated carbon powder to absorb the organic matter in the solution to keep the solution clean.
When the filter is cleaned, the operator does not completely clean the impurities in the filter cartridge, and it is easy to leave a small amount of impurities. When starting the startup, the filter cartridge is easy to flow into the liquid tank with impurities, in order to prevent negligence caused by human operation. It is specially designed with a circulation loop to provide convenient operation.
Points to note when operating the filter
Before operating the filter, it is necessary to check whether the inlet and outlet pipes are installed, and fix the inlet and outlet pipes in the groove so that the inlet and outlet are not easy to swing. Open the exhaust valve and then open the drug valve, and the water from the dosing valve into the pump and inlet tube through the dosing tank, so that the inlet pipe is completely filled with liquid, or open the filter cover to remove the upper cover, and the water is filtered. The barrel is injected so that the inlet tube is completely filled with liquid. Check the operating voltage and motor wiring voltage correctly before starting the motor to prevent errors. Before starting the motor, lock the dosing valve and then open the exhaust valve to allow the gas to be discharged into the dosing tank. After the above operation is completed, when starting the pump motor to start operation, pay attention to whether the pump is running in the correct direction. The liquid in the dosing tank flows through the dosing valve into the pump, and a small amount of liquid remains in the dosing tank, and then the dosing valve is locked to avoid inhaling gas at the pump inlet. Before using the filter, check whether the pressure gauge diaphragm is filled with clean water. Please fill up the water and lock the pressure gauge to keep the pressure gauge correct. Before starting the power supply, check whether the inlet and outlet pipelines are correctly selected: such as: whether the inlet and outlet are open, whether the pipeline circulation route is correct, whether the liquid in the liquid medicine tank is normal, and whether the pipeline is damaged. Operate in a hazardous environment or liquid, wear protective clothing and protective masks, safety footwear. Check various protection switches. For example, if the pipeline is normal, the liquid level in the tank is normal, and the power protection switch is in the normal operating position.
