Pump foundation height
Thread Content
Air pockets are not allowed at the pump’s inlet, which results in a particularly high base for the pump. What should be done? What are the disadvantages?
What's going on? I guess: the pump inlet pipeline comes down from the ground? Is the top of the eccentric head flat? Is there also a low-point vent required in the straight pipe section ahead of the large and small heads, as well as behind the pump inlet valve?
The pump foundation is set at a higher level, mainly to facilitate maintenance, prevent water flooding, and enable easy drainage. Is it related to the air bag?
The presence of air pockets may lead to cavitation. It exits from the pipe pier in the tank area and enters the pump pipeline, branching off from above to the pump’s inlet.
The lower the relative installation height, the less likely cavitation is to occur, right?
Yes, this will cause cavitation at the pump inlet.
