Abstract
PURPOSE: To enable to drive the pump with high efficiency to the lines having different pressures by a method wherein an impeller is housed in the inside of a stationary blade at the drive shaft side at low pressure running and the impeller is located at the front stage of the stationary blade at high pressure running.
CONSTITUTION: At low pressure running, when a closing valve 36 is open to communicate a bell month part 17A to an inner tube 20B, because the pressure in the inner tube 20B is lower than the pressure before the secondary stationary blade 23, the secondary impeller 25 is applied by an upward thrust and is moved upward to be housed into the inside of the stationary blade, without an air cylinder continuing to be supplied with the air. At high pressure running, when the closing valve 36 is closed, because the pressure at the secondary stationary blade 23 side is lower than the pressure is a primary stationary blade 22 side, the secondary impeller 25 is applied by an downward thrust and is moved downward to be located at the front stage of the secondary stationary blade 23, without the air cylinder continuing to be supplied with the air in the same manner as at the low pressure running. In the manner as described above, the pump can be driven with high efficiency to the lines having different pressure.
