Abstract

PURPOSE: To prevent generation of cabitation in a high pressure pump by supplying forcedly through the high pressure pump the oil contained in an oil tank installed separately from the bearing oil tank for a rotary machine used in a vertical rotary electric machine etc.
CONSTITUTION: An end of an oil feeding pipe 14 in communication with a high pressure pump 13 shall be opened in an oil tank 11. As this oil tank 11 is located below a bearing oil tank 5 and in cmmunication with it through a small hole 12, the lubricating oil in the oil tank 11 is independent of the lubricating oil 6 in the bearing oil tank 5. Further, as the tank 11 is isolated below the rotary shaft 1 and a rotary part of runner 2 etc., it is free from affection of air bubbles produced by revolutions, and the high pressure pump 13 is supplied with oil including no air bubbles. Accordingly, the high pressure pump can be prevented from generation of cabitation.
