What causes the check valve to make a ‘dinging’ sound when the circulation pump is turned on?
It’s probably due to large fluctuations in traffic
Large fluctuations in gas volume, low inlet pressure
Is it a leak inside the check valve, causing backflow due to high system pressure? Something similar just happened when we started up our unit.
1. Insufficient airflow. 2. Too low pressure. 3. Unstable pressure. Additionally, our company’s hydrogen pipeline system also uses a one-way flow mechanism, and the system is equipped with grounding protection; I’m not sure if continuous beeping sounds could pose any safety risks.
Reply to 8# chenhj20040921: A check valve is simply a one-way valve that prevents backflow. If there is noise, it’s likely due to low pressure, unstable air flow, and excessive fluctuations. It is recommended to check the pump
The flow rate is unstable, and the pressure fluctuates.
