Centrifugal pump balance tube
Thread Content
Why are some connected to the outlet and some connected to the entrance? What is the principle of connecting to the outlet?
This is the mechanical seal flushing plan, the first picture is PLAN11, the second picture is PLAN13
This is not a balancing tube, this is a flushing scheme, implemented in accordance with API standards.
The balance tube is connected from the inlet to the gas phase of the tank
The balance pipe of a centrifugal pump should be a concept in the form of a multi-stage pump. In order to balance the axial force, the high-pressure medium is led from the pump outlet to the back of the first-stage impeller.
Please tell me why we use double machine sealing when there is self-flushing.
