Lubricating system for a turbomachine including a method of operating same

摘要

A lubrication system for a turbomachine includes a primary pump operatively connected to the rotor of the turbomachine. The system further includes independently driven stand-by pump means for maintaining lubricating oil flow to the turbomachine when the primary pump is unable to deliver the oil as required. The system further includes a by-pass connecting the primary pump outlet to the oil reservoir. The by-pass is activated for permitting oil flow from the primary pump outlet to the reservoir when the secondary oil pump is activated.
