Solutions for overheating and cavitation in centrifugal pumps? Help needed
Thread Content
In chemical processing plants, centrifugal pumps handle media at high temperatures; it is therefore necessary to cool the impeller. Do any experts have any good solutions? The current method is to water the impeller housing, but this isn’t a sustainable solution
From the perspective of design selection and material choice, 300°C to 400°C is no problem.
Was the medium temperature not taken into account when selecting the pump?
High temperature is not a problem; the problem is cavitation! It can increase the inlet pressure, reduce the pump height, lower the pump’s net positive suction head, and overcome cavitation issues!
Heat exchange cooling can be applied to the pump inlet pipeline.
Raise the liquid level, or increase the pressure on the liquid surface, etc
Send me the parameters and I’ll do the calculation~
Has the device been finalized? Then change the process, or replace the equipment, from level 2 to level 4 ； If it still doesn’t work, there’s nothing else to do
