Dear All,
We are working on cooling water pumping system; we needed to increase capacity of existing cooling water system with available pump which is having high head and low flow. We have installed this pump with orifice and operated in parallel to existing pump. Now with this parallel operation we are facing noise and vibration at downstream of orifice. Data for the pump and orifice is as under
Pump flow; 2650 USGPM
Pump discharge pressure; 12.5 barg.
Pressure at downstream of orifice; 5.7 barg
Orifice size; 3.66-inch
Pipe size: 10-inch
We have gain in capacity with this addition of this high head and low flow pump
If anyone can suggest solution to avoid noise and vibration issue, Please share your thoughts
Regards
