Well I received a response from the OEM re: lubrication pressure & flow requirements. The high flow rates are based on a worn balance device, which in turn produces the maximum thrust imbalance. Flow rate indicated is ultra conservative. The pressure they originally quoted was also incorrect and...
ccfowler,
Real estate (or lack of) is my main problem. Existing lubrication is piggybacked off the pumps variable speed coupling. Unfortunately the system we run has been expanded upon over the years, and this has lead to very little space between our 5 pumps, not to mention the other rotating...
Thanks for both responses to date.
I agree going away from OEM requirements is fraught with danger. The OEM will specify figures that cover the whole range of operation and in our application I believe our control system prevents the worst cases that they would be catering for. Having enough...
Hi all,
The company I work for has purchased a number of Boiler Feed Pumps for retrofit in our boiler plant. BFP selected has journal radial brgs & a tilting pad thrust brg. The OEM is requesting pressurised oil supply in the order of 20L/min at 250kPa for the thrust brg.
Our previous pumps...
