The heat exchanger is making a thudding sound
Thread Content
The tube side of the heat exchanger contains circulating water, while the shell side carries the fluid; there’s a constant knocking sound. What’s going on? I hope experts can explain this
What is the temperature of the material? It will vaporize at that temperature
It is already at secondary condensation; the temperature of the circulating water is not high, and there is no gas present
The steam from the jet pump has also decreased; there’s still that thudding sound, and this didn’t happen when it was running before
It is possible that the material in the shell side has not been completely condensed into a liquid state, containing gas
The sound coming from this cooler is probably the sound transmitted by the pipeline check valve, right? Or are there other sound sources being transmitted over? As long as there is no air hammer phenomenon (the sound caused by sudden vaporization and condensation) in the media on both sides, the sound will still be transmitted; therefore, it is still necessary to locate the source of the sound.
The thudding sound coming from the heat exchanger is loud and distinct if it is quite sharp in tone. It can be generally concluded that there is a gas-liquid two-phase flow, resulting in destructive water hammer phenomena. First, it is necessary to determine what the pressure and temperature of the circulating water in the tube side are What state is the material in the shell side (solid, liquid, gas)? Will a state of two identical flows occur? Once the cause of the problem is found, it can be solved
There must be some non-condensable gas remaining inside; it needs to be vented (if it’s indeed coming from the heat exchanger). PS. The cooling water should be relatively clean; it’s better for it to flow along the shell side...
Is it the sound of the check valve disc hitting something?
