This is a check valve at the outlet of the vacuum pump; whenever the vacuum pump starts, the check valve emits a \"clicking\" sound as its valve element keeps hitting against something. Is there a problem with the valve selection? Is there an issue with the installation? 2306
Hello, based on the information you provided, this issue might be caused by problems related to valve selection or installation. It may be necessary to check whether the appropriate valve type has been selected and whether it is installed correctly. It is recommended that you contact the relevant technical personnel for a more detailed inspection and analysis to find a solution. .
This phenomenon occurs when the pressure difference across the valve changes. If the fluid is continuously transported, this phenomenon will not occur, such as in turbines. In the case of reciprocating pumps, such periodic pressure fluctuations occur, as in piston-type pumps. This sound should be normal operation; it’s likely a reciprocating pump. For reference.
It’s a problem with valve selection. The excessive spring force inside the check valve, which is not compatible with the pumping capacity of the vacuum pump, results in continuous ‘pop’ sounds. For reference
