Abstract

PURPOSE: To contrive not to cause delay in exhausting air when starting a pump under the condition of pressing down the water level by installing exhaust ports, exhaust chambers to exhaust air in runner chambers and in their flow paths, and water sealing devices on a multiplestage pump water wheel equipped with a movabl guide vane.
CONSTITUTION: With a movable guide vane 10 in fully closed condition, compressed air is blown in, water that is put lower than a runner chamber 5 is pressed down to directly below a low-pressure stage runner 3, both a high-pressure stage runner 2 and the runner 3 are started in the direction of a pump, and at the same time as they are arranged in parallel with the system, exhaustion is started through an exhaust pipeline 30. With progress of exhaustion, water level in a blowpipe 17, and are stagnates in the middle of the runner 3, which becomes the condition surrounded by water wall. When the water arrives at the runner 2, air stagnates also in the runner chamber 5, so that air is exhausted through a then open exhaust pipeline 34, after completion of exhaustion, the guide vane 10 is opened to make water lifting operation. For the purpose of exhaustion, because exhaust chambers 28, 31 on the outlet sides of exhaust ports 29, 32, and water sealing devices 22, 25 which comprise labyrinth paths 24, 26 are installed, air in the runner chambers 5, 6 are exhausted without delay.
