Abstract: The axial flow pump uses the thrust (lift) generated by the rotation of the impeller on the water body. It is a large flow and low lift water pump. There are vertical, horizontal, inclined and cross-flow types. kind. The following will introduce to you the models and parameters of axial flow pumps as well as the advantages of axial flow pumps. The models and parameters of axial flow pumps introduce the advantages of axial flow pumps
Advantages of axial flow pumps
Since the motor and water pump are integrated, there is no need to perform labor-intensive and time-consuming work at the installation site. The assembly process of motor, transmission mechanism and water pump axis alignment makes on-site installation easy and fast.
Due to the submersible operation, the actual geotechnical and structural engineering of the pump station can be greatly simplified, the installation area can be reduced, and the project cost can be saved by 30~40%.
The noise is low and there is no high temperature in the pumping station, which improves the operating environment. A fully underground pumping station can be built as required to maintain the environmental appearance of the ground.
The submersible motor adopts double or triple mechanical seals, class F (temperature resistance 155.C) insulation, and protection level is IP68 (IEC). In terms of hydraulic models, we have absorbed the advantages of similar products at home and abroad, adopted the most advanced variable circulation and variable shaft surface velocity lift methods in the world, and independently designed a new hydropower model that is highly efficient, energy-saving, and has good anti-cavitation performance. It has high reliability and is interchangeable with traditional water pumps, making it easy for users to select and use.
Easy to operate, easy to achieve remote control and automatic control.
Using this type of submersible electric pump is the most thorough way to build pump stations along rivers and lakes where water levels fluctuate greatly, and to solve motor flood control problems. It also eliminates the need for long shafts and intermediate bearings between pumps. Make the unit operation more reliable.
QZB type submersible electric pump can be used for farmland drainage and irrigation, and can also be used for industrial and mining docks, urban construction, water supply projects, and power station water supply and drainage. The transmission medium is raw water or does not contain large particles or long fibers. For sewage, the maximum temperature of the transported liquid is 50°C.
