Claims

[Scope of utility model registration request]

(1) A water supply device for a water-lubricated bearing having a bearing surface formed on the circumferential area of the main shaft of a hydraulic machine, including a main bearing water supply pipe that supplies pressurized water from a main water supply source to the bearing, and a water supply pipe inside the water supply pipe. a check valve inserted in a direction to prevent pressurized water from returning to the main water supply source, and a main bearing water supply pipe connected from the auxiliary water supply source to the main bearing water supply pipe between the check valve and the bearing. an auxiliary water supply pipe for supplying pressurized water to the water supply pipe; a check valve inserted into the water supply pipe in a direction to prevent pressure water from returning to the auxiliary water supply source;
a pressure reducing valve that is inserted into an auxiliary water supply pipe between the check valve and the auxiliary water supply source and reduces the pressure of the pressure water from the auxiliary water supply source to a pressure lower than the pressure water from the main water supply source; A water supply device for a water-lubricated bearing of a hydraulic machine, characterized in that when water supply from the main water supply source to the bearing is cut off, water is supplied from the auxiliary water supply source to the bearing.

(2) Scope of Utility Model Registration The water supply device according to claim 1, characterized in that the hydraulic machine is a water wheel and the auxiliary water supply source is an inlet waterway to the runner. .
