Description

technical field

[0001] The invention relates to a vertical centrifugal pump. Background technique

[0002] With the development of society, vertical centrifugal pumps are more and more widely used in various fields of the national economy, and the performance requirements for vertical centrifugal pumps are also increasing day by day. High head and efficiency, or a combination of the two forms, and secondly, new requirements are put forward for the material, structure and size of the vertical centrifugal pump, such as material saving, compact structure, relative uniformity of size, etc. , again, with the development of power machines and transmissions, the efficiency and speed of vertical centrifugal pumps have been improved, and higher requirements have been put forward for the reliability of vertical centrifugal pumps. In short, the design of vertical centrifugal pumps should be improved Efficiency, saving energy, improving the reliability of operation and extending the se...
