With the continuous development of industrial technology, high temperature resistant self-priming pumps have been widely used in many fields. This article aims to conduct an in-depth study on the selection of high-temperature resistant self-priming pumps and explore the key factors and precautions in the selection process.

Fire pump is a kind of equipment specially used to carry water source and transport fire-extinguishing water. It is widely used in various buildings, factories, docks, mines, ships and other places. It plays a vital role in controlling and extinguishing fires.

The vertical pipeline pump has a vertical structure. The inlet and outlet diameters are the same and located on the same center line. It can be installed in the pipeline like a valve. It is equipped with installation feet to increase the stability of the pump. It has a compact and beautiful appearance and takes up less space. The area is small and the construction investment is low. I introduced how to solve the vibration and failure of vertical pipeline pumps during use.

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 material characteristics of flow-passing parts on cavitation in centrifugal pumps.

The factors affecting centrifugal pump cavitation are issues that must be considered in the design and use of centrifugal pumps. In recent years, a lot of research has been carried out at home and abroad. However, due to different focuses of research, and most of them are conducted on a certain parameter that affects centrifugal pump cavitation, the research results are scattered and some of the opinions are contradictory. This article analyzes the impact on cavitation from the perspective of fluid physical properties.

The vertical multi-stage centrifugal pump is a non-self-priming vertical multi-stage centrifugal pump designed and manufactured by absorbing advanced domestic and foreign technologies. It uses a standard vertical motor and a quick-install mechanical seal, which is very convenient to replace. A slight carelessness during the installation of a vertical multi-stage centrifugal pump will lead to improper installation and affect the performance of the pump in the future.

Submersible sewage pumps often cause motor windings to burn out due to lack of water in the pool. The main components of WQ submersible sewage pump are composed of impeller, pump body and base submersible motor. Modified sewage pumps are mostly used in construction sites, septic tanks and other environments with sewage and debris. The water pump and the all-copper motor are on the same shaft. Since the water pump is located at the bottom of the entire sewage pump, it can maximize the suction of residual sewage on the ground.

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.
