Abstract

PURPOSE: To prevent the occurrence of surging by controlling a bypass amount from a bypass hole piercing from scroll to impeller inlet by a method in which a throttling means is controlled by a controller operating through the flow rate in the suction side and the pressure in the discharge side.
CONSTITUTION: A bypass flow rate necessary at the flow rate indication regulator 6 is calculated from a pressure difference signal of the flow rate measuring orifice 2 and a discharge pressure signal of the pressure signal generator 4. And, a signal of bypassed amount from the flow rate indication regulator 6 is sent to the regulator 20, the opening area of the bypass hole 17 piercing from the scroll 12 to the impeller 8 inlet, which is necessary for bypass flow rate needed on the inlet side, is calculated, and the moving amount of the piston 15 for obtaining the opening area is sent to the power cylinder 21. Thus, the opening area of the bypass hole 17 can be changed into a necessary size, and also the occurrence of surging can be prevented by returning a part of the pressurized water to the discharge side of the suction side.
