Hi :),
We have a HP pumping system (6000 Psig discharge pr). Installing these pumps in nearby with common discharge header. We have the following details from the manufacturer regarding the pump vibration.
1. Pressure variation + or - 13 Bar
2. Pump unit frequency 2.5 to 25 Hz
3. Maximum disch. flange displacement + or - 1.5 mm in all planes
Nozzle allowable loads are recommended to consider as per API 610, but it is not a centrifugal pump (Reciprocating).
We did a static analysis considering the nozzles as anchor point and getting the loads on disch nozzle is bit high than recommended as per API 610.
My doubt is as follows.For static analysis whether we have to consider the nozzle initial displacement as recommended by supplier (+ or - 1.5mm)
Is it required to do the dynamic analysis. If so pls suggest some reference.
Allowable load verification as per API 610 is OK?Thx
