Issues with the balance pipe of the hydrorefining feed oil pump

2016-06-28View Original

Thread Content

It is a horizontal multi-stage centrifugal pump, with an outlet pressure of 7.0–7.5 MPa. There is a pressure gauge on the balance pipe; under normal conditions the pressure there is around 0.1 MPa. However, recently it has been observed that the pressure indicated by the gauge has decreased, and basically no pressure is generated anymore. What determines this pressure?

Are you sure the pressure in the balance tube is 0.1 MPa? It’s time to replace the pressure gauge.
