reason for connecting (short) pump inlet & outlet
reason for connecting (short) pump inlet & outlet
(OP)
hello mechanical engineers!!!
I'm an Electrical professional working at power plant where i have to deal with mechanical equipment too, like pumps, HX etc....
here in plant there a pump producing high pressure, around 20MPa while suction pressure is only 0.2 MPa. thus there is 19.8 MPa delta across the pump. due to that huge pressure difference a small line of shorted inlet & outlet. i checked pressure of shorted line which is only 0.3. i ask one of the mechanical engineer about it, he told me this line gives protection against huge pressure difference. but it is far from my understanding as it recover only 0.1 MPa. is my colleague right about it??? if yes than what is science behind it??? if not than what could be actual reason to shorten the pump inlet & outlet???
looking forward for reason with best regards.

It is unclear exactly what you are describing

But we cannot tell with a Manufacturer and Model number
You need to find the O&M manual and brush-up on the pump details
Your mechanical colleague really hasn't provided a good explanation.

It might show something like the device describe in the link referanced by JJPellin
