Pneumatic diaphragm pumps are placed in various special occasions to pump various media that conventional pumps cannot pump, and have achieved satisfactory results. In the process of using various series of pneumatic diaphragm pumps, we occasionally encounter the phenomenon that the pneumatic diaphragm pump suddenly crashes and does not work. This article introduces the reasons why the pneumatic diaphragm pump does not work.

Pipeline centrifugal pumps are used to transport clean water and other liquids with physical and chemical properties similar to clean water. They are suitable for industrial and urban water supply and drainage, pressurized water supply in high-rise buildings, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC and refrigeration cycles, Hot and cold water circulation and pressurization and equipment supporting facilities such as bathrooms. This series of pumps have excellent performance, high reliability, long life, reasonable structure and beautiful appearance, and are industry-leading.

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 chemical industry's requirements for fluid transportation equipment mainly include high efficiency, stability, safety, etc. As an important fluid conveying equipment, screw pumps have the advantages of compact structure, stable operation, and a wide range of conveying media, and have been widely used in the chemical industry.

The technological innovation and development of vacuum-started drainage pumps are the key to promoting the sustainable development of related industries. Through exploration and practice in material innovation, structural optimization, intelligent control, energy conservation, environmental protection, and multi-functionality, the performance and efficiency of vacuum-started drainage pumps can be continuously improved to meet market demand.
