Vibration in the inlet and outlet pipelines of the graywater circulation pump
Thread Content
During operation, due to the lack of system pressure, the inlet and outlet of the graywater circulation pump experience significant vibration. Attachments such as drain pipes and pressure gauges on the water supply pipeline of the carbon scrubber tower were broken off. Once it’s started up, the system pressure will be established. Does anyone have any good suggestions? Can these pipelines be secured with rigid fixation? Or is the operation not proper?
This is also due to the fact that the water circulation time cannot be too long; another reason is the extremely high water temperature. It could also be caused by poor flashing of the water entering the system, as well as the presence of non-condensable gases at the pump inlet.
The problem is that the outlet pressure is too high when the pump is started; it’s much higher than the system pressure. One is to add a bypass to the outlet pipeline, and the other is to add a flow-limiting orifice plate.
