Vibration in the inlet and outlet pipes of the membrane press

Vibration in the inlet and outlet pipes of the membrane press is mainly caused by the flow of high-pressure hydrogen. To eliminate pipeline vibration, the following methods can be adopted: 1. Increase pipeline support: Add sufficient pipe supports to the inlet and outlet pipes to stabilize them and reduce vibration. 2. Increase pipeline stiffness: Reinforcing elements can be added between the inlet and outlet pipes to enhance the stiffness of the pipes and reduce vibrations. 3. Reduce flow velocity: Lower the flow velocity by increasing the pipe diameter or reducing the flow rate, thereby reducing the impact force of the fluid on the pipe and minimizing vibrations. 4. Use hose connections: Hoses possess good flexibility and sound-absorbing properties, allowing them to absorb some of the vibration energy and reduce pipe vibrations. It should be noted, however, that the selection of hoses must meet the working conditions and pressure resistance requirements. 5. Improve pipeline stability: Check whether the pipe connections are secure; if any looseness is detected, it should be repaired promptly. Furthermore, specialized equipment such as vibration absorbers can also be considered to eliminate pipeline vibrations. Please consider the above suggestions comprehensively based on the specific circumstances, and choose an appropriate method for handling the situation. .

The analysis is thorough and comprehensive; thank you very much!

Vibrations are caused by a sudden change in the fluid flow. It is necessary to analyze the reasons from various perspectives. Such as the volume of imported gas, and the suitability of the selected model, etc. . .

Additional note 1: Add a flow-limiting orifice plate

We originally had an acrylic compressor; after adding pipe fixations, the welds of the two-return-one valve assembly cracked. We need to find the cause at its source. I wonder if increasing the exhaust buffer tank would help
