Problems with the balance pipes of turbine condensate pumps
Thread Content
Is the balance pipe of the condensate pump kept open during equipment operation?
Yes, turn it on before starting the pump, and keep it in the on state
It really needs to be left on all the time. Does the original poster have any concerns? ? ?
If the valve of the balance tube is opened wider or narrower, does it have an impact on the pump’s outlet pressure?»
It has no effect on the outlet pressure; it only affects the direction and magnitude of the axial force. These values are set at the time of manufacturing, and it is recommended not to make any arbitrary adjustments
Once the function of the balance tube is understood, one knows what to do.
