Cross-line between the primary and backup pumps in the cooling water station
Thread Content
As shown in the figure, this is a cooling water station for a reciprocating compressor. A bypass line is installed at the outlets of the primary and backup pumps, along with flow-limiting orifice plates. May I ask everyone **what the purpose of these elements is here?**
Ours too; we’re really curious.
It can also prevent accidental operations, such as the shutdown of the reflux flow; when switching the reflux mode,
In some cases, the designers and users are not on the same page
Bypass line – used for the trial operation of the pump, or to keep the pump running when the main outlet valve is closed under abnormal operating conditions. Bypass valves equipped with flow-limiting orifices are generally installed in situations where the pressure difference before and after the valve is very high
I thought about it; its main function is to prevent freezing and condensation, not to act as a heat pump.
Is it to balance the pressure of the two pumps when reversing the pump direction, in order to ensure that there are no fluctuations in system pressure?
