Document Type and Number:
Japanese Patent JP3125533
Kind Code:
B2
Abstract:
PURPOSE: To provide a barrel casing type turbine pump where noise can be reduced at a specific rotating speed.
CONSTITUTION: A water extracting chamber 9 and a discharging chamber 10 are divided via a vibration insulating member 11 interposed between an outer casing 1 and an inner casing 5. The vibration insulating member 11 is brought into contact with the outer casing 1 and the inner casing 5 due to a fluid pressure to be exerted on the inner casing 5, to thus seal the outer casing 1 and the inner casing 5 and insulate vibration to be propagated from the inner casing 5 to the outer casing 1.
