Abstract

PURPOSE: A hydraulic machinery which produces upward water thrust which is not so great as a runner is forced up and little downward water thrust.
CONSTITUTION: A hydraulic machinery involves a balance pipe 10 which connects a back pressure room 6B of a runner 4 to a side pressure room 8 or draft pipe, and a valve 11 provided in the way of it. A supporting member 40 whose external surface is fixed on a concrete wall 70 to support a pad 52 of a runner 51 of a thrust bearing provided around a main shaft 1 is provided with a diaplacement gauge 41 which detects thrust force applied on the member 40. and puts an electric signal to control servo-motor 60 to regulate said valve 11. Water thrust applied on a runner 4 to affect the supporting member 40 through the thrust bearing runner 51 and the pad 52 is properly controlled continuously by adjusting the opening of the valve 11 under the control of the diaplacement gauge 41 and the serv0-motor 60
