Centrifugal pumps are an integral part of industrial fluid delivery systems and are widely used in petrochemical, pharmaceutical, food processing and many other fields. 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, in practical applications, mechanical seal damage is a common problem, which will not only lead to a decrease in pump efficiency, but may also cause safety hazards such as leakage. Therefore, it is of great practical significance to explore the causes and treatment methods of mechanical seal damage of centrifugal pumps.

The stator of the G-type single screw pump is made of rubber and is a wearing part of the single screw pump. Its selection will directly affect the life of the stator. Under normal circumstances, the life of the stator is 3-6 months. If it is not selected properly, The stator may fall off the steel tube or the rubber may fall off.

With the transformation of the global energy structure, new energy technologies have developed rapidly. As a key equipment for heat energy transmission, hot oil pumps are increasingly used in the field of new energy. This article aims to discuss the application and importance of hot oil pumps in the field of new energy and provide reference for the development of new energy technology. Current application status of hot oil pumps in the field of new energy

The factors affecting centrifugal pump cavitation are issues that must be considered in the design and use of centrifugal pumps. However, due to different research focuses, and most of them are research on a certain parameter that affects centrifugal pump cavitation, the research results are relatively scattered. , and some of the views are contradictory. This article analyzes the impact of centrifugal pump structural design on cavitation in centrifugal pumps.

High-temperature hot oil pumps are widely used in the food industry. They can not only provide a stable heat source to ensure that food reaches the required temperature during processing, but also improve the quality and safety of food.
