Centrifugal pump inlet diameter?
Thread Content
At the bottom of a circular-bottom tank, there is an outlet at position 80; after passing through a vertical elbow, 1 meter of straight pipe, a horizontal elbow, and another 1 meter of straight pipe, the fluid reaches a centrifugal pump. The model of this pump is GZA 80-65-200. Its flow rate is 60 cubic meters per unit time, its head is 25 meters, and its power consumption is 7.5 KW. The liquid is to be pumped to a storage tank that is less than 10 meters high and located about 30 meters away. The outlet diameter changes directly to 100 millimeters. Currently, the pump tends to experience cavitation issues; the actual liquid level in the tank is around 1.5 tons. Request to know.
Having free time has nothing to do with the outlet. Import pressure? Medium concentration?
The outlet valve is too tight; add a liquid level alarm and automatic pump shutdown when the liquid level is low.
Find the reason – vortices are forming inside the imported tank
All of these occur; the reason is clear: vortices are formed inside the tank
The flow rate is 60 cubic meters, but the outlet at the bottom of the tank is only 80? I wonder if the diameters from the bottom outlet of the tank to the pump inlet are both 80? The flow velocity is already 3.4 m/s.
Both the bottom outlet of the tank and the pump inlet are 80
