The meaning of viscosity on the screw pump label
Thread Content
A double-thrust centrifuge of model HR500 is in use, along with a screw pump. One of the parameters of this new pump differs from that of the existing pump: the new pump has a flow rate of 40 MM2/S, while the existing pump has a flow rate of 75 MM2/S. It’s not clear whether the new pump can be used. The oil used in this equipment is 36# non-reverse steam turbine oil; what significance does viscosity have in this context? Please tell me!
If the viscosity is lower, the motor power might be a bit smaller; the flow rate will also be lower. Just use a larger motor
Does it mean that the gap between the screws is smaller?
The viscosity changes little, so there is no significant impact.
