Calculation of safety valves
Thread Content
In the calculation of the safety valve for a gear pump, how should the safety discharge volume be determined? Should the closure of the outlet valve be taken into account? If that’s the case, the safety valve will be very large.
The safety discharge rate is the maximum flow rate of the pump.
It should be considered to close the outlet valve, and the calculation should be based on the maximum normal flow rate of the pipeline
What should be considered is the pump’s maximum flow rate, I guess
The main step is to select the appropriate operating conditions and calculate the minimum discharge area; for specific calculations, reference can be made to HG_T20570-95 \"Technical Specifications for the Design of Process System Engineering\"
