Submersible axial flow pump impeller information

Submersible Axial Flow Pump Impeller is the main working part of the axial flow pump, its performance directly affects the pump performance. Impeller according to the possibility of regulation, can be divided into fixed, half-tone and full-tone three. Fixed axial flow pump is made of blades and hub body, the installation angle of the blade can not be adjusted. Semi-axial flow pump its leaves are bolted to the hub body, the root of the blade engraved with a baseline, and in the hub body engraved with a number of the corresponding installation angle of the position line, the blade of different installation angle, Its performance curve will be different. According to the requirements of the use of the blade can be installed in a certain position, in the course of the use, such as changes in the conditions need to be adjusted, you can remove the impeller, the nut loose rotation of the blade, the blade of the baseline alignment wheel The body of a request angle line, and then tighten the nut, the impeller can be installed. Full-scale axial flow pump is the pump can be based on different head and flow requirements, in the case of downtime or non-stop, through a set of hydraulic adjustment mechanism to change the blade installation angle, so as to change its performance to meet the requirements , This full-scale axial flow pump adjustment mechanism is more complex, generally used in large axial pump station.
