Self-suction centrifugal pump and its development

Self-suction centrifugal pump and its development Current status of self-priming centrifugal pumps With the development of economy, self-priming centrifugal pumps have been more and more widely used in the project. The following describes the current status and direction of self-priming centrifugal pumps in detail.

Because of its simple installation, small footprint, easy maintenance, and no noise, the self-priming centrifugal pump is widely used in the project to discharge sewage from municipal projects, factories, businesses, hospitals, hotels, and residential areas. At present, China's domestic self-priming centrifugal pumps are mainly produced and manufactured by domestic manufacturers, and a small part of the products are imported from abroad. The market prospect is very broad. However, due to the need to strengthen the reliability of the sewage pump, improving the technical content of its products is the main direction for future development of the manufacturers.

The development direction of self-priming centrifugal pumps For the problems of self-priming centrifugal pumps, some domestic manufacturers have put their energies on developing the protection system of the pump: automatically alarm or cut off the power when an abnormality occurs in the operation of the sewage pump. Although this method can have a certain effect, and this protection is also necessary, but this is not the fundamental method to solve the problem, we must also focus on improving the performance of the pump to fundamentally solve the problem.

In addition, product development must fully consider the environmental issues, so that the products developed are more energy-efficient and environmentally friendly.

In summary, the problems to be solved in the future for submersible sewage pumps are to improve the reliability of use, to adapt to a variety of working environments, to optimize their structural design, and to further improve the performance of self-priming centrifugal pumps.

The design of the double row angular contact ball bearings is basically the same as the single row angular contact ball bearings, but only takes up a smaller axial space. The Double Row Angular Contact Ball Bearing can bear radial load and axial load in two directions. It can limit the two way axial displacement of shaft or shell, and the contact angle is 30 degrees. It can provide a high rigid bearing configuration and can withstand the overturning moment.

Application: compared with single row angular contact ball bearings, the double row Angular Contact Ball Bearing has better rigidity and can withstand the overturning moment. The bearings are non - separate. It is especially suitable for applications with high rigidity. It is widely used in the front wheel hub of a car.
