Flow over by the suction tank water, through the suction horn tube, because the impeller blades of the impeller chamber to force the water rotation, so that the water into the guide vane, the energy conversion generated through the pump head, the cylinder is discharged from a drainage pipe. The pump through the coupling (rigid) and intermediate shaft coupling. The bearing under the motor bearing bears all the downward axial force of the rotor. Coupling elastic coupling with the intermediate shaft and the motor shaft.
Axial flow pump impeller (hub body) with a blade, according to whether the performance parameters of the pump can be adjusted to change the pump, axial flow pump in the following three:
Fixed axial flow pump - impeller (wheel hub) and blade for the overall structure, the blade is not adjustable;
Semi adjustable blade axial flow pump impeller (hub body) and blade of composite structure can only be stopped, remove the blade adjusting blade mounting angle (such as 0 degrees, plus or minus 2 degrees, plus or minus 4 degrees, plus or minus 6 degrees, plus or minus 8 degrees), adjust the angle of the stairs;
Fully adjusting blade axial flow pump through a set of regulating mechanism (mechanical or hydraulic), the pump can be used in the operation of manual, electric, computer control, etc., to carry out the blade angle of the stepless regulation.
