Precautions For Polymer Electrolyte Membrane Electrolysis:
Gas Leak Prevention: Regularly check hydrogen lines and connection points to ensure there are no leaks. Use hydrogen detectors to detect and resolve problems in a timely manner, while ensuring that the work area is well ventilated to prevent hydrogen accumulation.
Operation Training: All operators must be properly trained to understand the working principles, operating procedures and emergency shutdown procedures of the equipment. Untrained personnel are prohibited from operating the equipment.
Maintenance Records: Keep detailed maintenance and operation logs to record all relevant activities, including routine inspections, maintenance services and resolution of any problems. This helps track the performance of the equipment and detect potential problems in a timely manner.
