Abstract
PURPOSE: To prevent a rapid lowering of a feed water pressure until a hydraulic machinery stops due to a power failure to stop the machinery safely by mounting a fly wheel on a feed water pump which is used to feed water to a hydraulic-lubricating bearing of the pump.
CONSTITUTION: A bearing 2, which bears a main shaft 1 of a hydraulic machinery, is pressurized by water fed by a pump 16 to control vibration of the machinery during its rotation. As a motor 20 to drive the pump 16 stops at the moment that the power failure occurs because the force of inertia of the motor 20 is small in general, a flywheel 21 is mounted to make up for the power to extend the time until the pump stops. When hydraulically pressurizing a static pressure type bearing by the pump, the flywheel 21 is mounted on the feed water pump 16 to prevent rapid lowering in the pressure when the feed water pump 16 stops. By such constitution, the hydraulic machinary can be safely stopped without giving abnormal vibrations to the shaft 1.
