The causes and treatment methods of the circulating pump stop involve many aspects, which need to be comprehensively considered and corresponding measures should be taken to ensure the normal operation of the pump.

There are many reasons for drainage pump leakage, and it is necessary to strengthen maintenance and inspection during use, and timely discover and solve problems to ensure the normal operation and efficiency of the pump.

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.
