Chemical centrifugal pumps refer to centrifugal pumps used in the chemical industry. Compared with other types of pumps, chemical centrifugal pumps have the advantages of simple structure, not easy to wear, smooth operation, low noise, uniform water output, convenient adjustment, and high efficiency. Therefore, chemical centrifugal pumps Centrifugal pumps are widely used.

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.

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.

Pneumatic diaphragm pumps and screw pumps are both positive displacement pumps. Pneumatic diaphragm pumps are pneumatic and do not produce sparks. Screw pumps are generally electric. The principle of both is the same. They both form a movable closed space to reduce the standard volume of fluid before the pump and increase after the pump, thereby increasing the pressure in front of the pump and reducing the pressure after the pump. Pneumatic diaphragm pumps are a very commonly used conveying machinery and equipment, and are recognized and trusted by the industry. People often confuse pneumatic diaphragm pumps and screw pumps. People confuse the two because they have the same characteristics, but in fact they are also very different.

The stator of the G-type single screw pump is also called a rubber sleeve. The inner wall of the rubber sleeve is made of rubber material. Since the gap between the rubber sleeve and the rotor (screw) is small, the G-type screw pump is prohibited from idling and must have liquid for use. There is lubrication between the rubber sleeve and the screw shaft. During the rotation of the rotor (screw), friction will occur with the rubber sleeve. If the transported liquid contains fine hard particles, the service life of the rubber sleeve will be reduced. It is recommended to use abrasive liquids. Low speed screw pump. So to extend the service life of the rubber sleeve, you need to reduce the wear of the rubber.

the control system of the diesel engine high-efficiency dry self-priming pump group is a powerful and complex system that can meet the needs of various complex working conditions and ensure the stable, efficient and safe operation of the pump group.

the diesel engine high-efficiency dry self-priming pump group is an advanced pumping system that integrates high efficiency, durability and safety. Its unique self-priming function and stable and reliable power output make it widely used in municipal drainage, industrial sewage, agricultural irrigation and other fields.

XBC diesel engine fire pump group may encounter a variety of problems during use, which may involve the start-up, operation, performance and other aspects of the equipment. This article is a brief analysis of some common problems.

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.
