In modern industry and urban infrastructure, multistage pumps are widely used due to their high efficiency and stable performance. Multistage pumps are composed of multiple single-stage pumps connected in series, and the pump head and flow rate are increased by increasing the number of stages. Therefore, the number of stages of a multistage pump becomes a key factor affecting its performance and application.

As a key device for handling water discharge problems, the importance of installation quality is self-evident. Correct installation can not only ensure the efficient operation of the pump, but also extend its service life and reduce the cost of subsequent maintenance. Therefore, it is very important for installers to master the installation skills of drainage pumps.

The drainage pump is a key device for handling water discharge problems, and its performance directly affects the overall operation of the drainage system. Therefore, when purchasing a drainage pump, you need to consider many factors to ensure that you choose a drainage pump with high cost performance and stable performance.

As a key equipment for fluid transportation, pumps are widely used in various fields. However, during the operation of the pump, cavitation often occurs, which not only affects the performance of the pump, but also may cause damage to the pump's flow-through parts and shorten the service life of the pump. Therefore, in-depth research on the cavitation phenomenon of the pump is of great significance to improving the operating efficiency and safety of the pump.

In the field of environmental protection and sewage treatment, self-priming sewage pumps are widely used due to their unique self-priming function. However, when faced with the problem of slow water absorption speed, it will directly affect its working efficiency and effect. Therefore, this article will explore several strategies to increase the water absorption speed of self-priming sewage pumps.

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.

The selection of sewage lifting pump station equipment needs to comprehensively consider the geographical environment, sewage flow and water quality characteristics, operation stability and reliability, maintenance convenience, degree of automation and use conditions. In the selection process, detailed analysis and comparison should be carried out in combination with the actual situation to select the most suitable pump station type and configuration plan.

In the fire protection system, fire pumps and sprinkler pumps are two important pieces of equipment. They have significant differences in functions, application scenarios, and working principles. This article aims to provide an in-depth look at the differences between these two types of pumps in order to better understand their role in fire protection systems.

As an important part of the fire protection system, the control and starting methods of fire pumps are directly related to the efficiency and effect of fire rescue. With the advancement of science and technology and the continuous development of fire protection technology, the control and starting methods of fire pumps are becoming more diversified and intelligent. This article aims to explore the control and starting methods of fire pumps in order to provide a reference for the optimization of fire protection systems.

As a common centrifugal pump, the self-priming pump has the advantages of compact structure, easy operation and stable operation. It is widely used in power, chemical, metallurgy, environmental protection and other industries. However, in the actual operation process, some self-priming pumps will have the problem of large sound and vibration, which not only affects the normal operation of the equipment, but also may cause noise pollution to the surrounding environment. Therefore, it is of great practical significance to study the causes and solutions of the large sound and vibration of the self-priming pump.
