Regarding the tank inversion issue with screw pumps
Thread Content
Dear sea friends, there is a problem that has been bothering me, and I hope everyone can share their opinions. I have two crude oil pumps, which are screw pumps, and they are normally used for supplying fluids to various devices. The outlet pressure is around 32 kilograms, and the flow rate is 110 cubic meters per hour. Can I use them as transfer pumps as well? Is the pressure still this high when used for inverted tank operations?
It can be used for pouring, and high pressure will not have any adverse effects
Screw pumps belong to the category of positive displacement pumps. The pressure generated by screw pumps can be adjusted using devices such as safety valves. If a higher pressure is not required at the outlet of the screw pump, its output pressure will decrease accordingly; therefore, screw pumps can be used as transfer pumps
One more question: what about a centrifugal pump with a head of 350 meters and a flow rate of 180 cubic meters per minute? It’s a crude oil pump with low viscosity – can it be used as a transfer pump as well?
If it is a centrifugal pump, there are no fundamental issues with using it; one only needs to ensure that the pump is not overloaded. It is necessary to control the flow rate during use to avoid problems such as overloading or excessive vibration of the pump.
