Stainless steel centrifugal pumps are widely used in many industrial fields due to their excellent corrosion resistance. However, different media have different corrosiveness, so how to optimize the material and surface treatment of stainless steel centrifugal pumps for specific corrosive media to extend their service life is a problem worthy of attention.

the light vertical multi-stage centrifugal pump has many advantages such as compact structure, excellent material, stable operation, and function, so it has been widely used in chemical, petroleum, pharmaceutical, metallurgy, water treatment, and industrial water supply.

stainless steel multistage centrifugal pumps have become indispensable fluid conveying equipment in modern industry with their high efficiency, stability and durability.

The installation of stainless steel multistage centrifugal pumps requires attention to determining the installation location, installation foundation, connection of inlet and outlet pipes, installation of brackets, installation of motors, position adjustment, grounding and wiring, as well as inspection and trial operation. Only when the stainless steel multistage centrifugal pump is correctly installed can its normal operation and safe use be guaranteed.

The maintenance method of stainless steel multistage centrifugal pump is essential to maintain its efficient and stable operation. Through effective maintenance methods, the stable operation of stainless steel multistage centrifugal pump can be ensured and its service life can be extended.

The structural design of the stainless steel multistage centrifugal pump is reasonable and compact, and the various components work together to ensure the efficient and stable operation of the pump. At the same time, its structure also provides convenience for the maintenance and maintenance of the pump.

The flow range of centrifugal pumps is usually large, and the flow adjustment methods are flexible and diverse, which is suitable for large flow and high head occasions; while the flow range of positive displacement pumps is relatively small, and the flow stability is better, which is suitable for small flow and occasions that require precise flow control.

This paper aims to explore the method of determining the geometric dimensions of the centrifugal pump impeller. By analyzing the working principle and design parameters of the centrifugal pump, combined with experimental data and theoretical calculations, a method for determining the geometric dimensions of the impeller based on similarity conversion method and performance optimization is proposed.

As an important equipment for industrial fluid transportation, the selection of centrifugal pumps is directly related to production efficiency and operating costs. The correct selection of centrifugal pumps can not only ensure the stable operation of the production process, but also effectively reduce energy consumption and maintenance costs. Therefore, this article will discuss how to correctly select a suitable centrifugal pump from the aspects of the working principle, selection principle, parameter calculation and practical application of centrifugal pumps.

As an indispensable fluid conveying equipment in industrial production, centrifugal pumps’ stable operation is crucial to ensuring production continuity. As a key component of a centrifugal pump, the performance of the mechanical seal directly affects the operating efficiency and safety of the pump. However, there are some common misunderstandings during the maintenance of centrifugal pump mechanical seals.
