Force feed versus ring oil lubrication
Force feed versus ring oil lubrication
(OP)
For one of the centrifugal pump and Hydraulic Power recovery turbine pump , the vendor is using Tilting pad bearings for thrust as well as Radial bearing. The rated kw of the Pump is 1200 kw . Vendor is offering to have ring oil lubrication ( No force feed with ext lube oil pump). As per Energy density formula given in API 610 this pump does not require Hydrodynamic lubrication. My query is , for tilting pad bearings , on reliability point of view , whether we can insist for Force feed lubrication? What are the factors to be looked into before accepting the ring oil lubrication for such a high power pump.Thanks to clarify

Do you mean hydrostatic? I don't know what API says but if the psi loading is too high then design rules push you in the direction of hydrostatic. The limiting condition is start/stop as stated. Frequent start/stop or need to rotate while secured may factor into your decision along with load.
