The membrane needs to be moisturized regularly. After moisturizing, care should be taken to ensure that there is half a tube of water in the inlet; if the tube is filled with water, it can damage the membrane. Additionally, when maintaining the oil pressure system, it is necessary to secure the electrolyzer tightly. If the ambient temperature is below -10 degrees, measures must be taken to insulate the electrolyzer.
The cell temperature must not be lower than 5 degrees to keep the membrane moist
Try to empty the liquid inside the tank. If it is going to be shut down for a few days, it is advisable to isolate the tank and keep the pipelines in circulation. If the moving equipment also needs to be stopped, then the liquid in the pipelines and equipment must be emptied to prevent crystallization; it is recommended not to shut down the system for long periods when temperatures are low
The electrolyte in the tank must be drained, and the tank must be cleaned according to the regulations. Nitrogen cannot flow through the cell (the membrane will dry and shrink). In winter, prevent the water seal at the end of the trough from freezing. When stopping the hydraulic press, lock the electrical tank first
When the electrolyzer is not in use for an extended period, it is important to regularly moisten and rinse the membrane. Of course, the water used should be drained to about halfway up the inlet hose, so that the membrane is not soaked. There is no need to evacuate the chlorine side, in order to prevent the membrane from becoming acidic； The temperature must not be lower than 5 degrees ；
Keep the inlet hose at a normal water level to keep the membrane moist; also, ensure the temperature is not too low
