Horizontal multi-stage centrifugal pump working principle

Horizontal multistage centrifugal pumps are often used to transport clean water or physical and chemical liquids. Today's horizontal multistage centrifugal pumps are mainly used in industries such as construction, factories and process industries. With the increasing influence of horizontal multistage centrifugal pumps, mastering the working principle of horizontal multistage centrifugal pumps is of great significance for the work of horizontal multistage centrifugal pump users. Horizontal multi-stage centrifugal pump working principle Horizontal multi-stage pump is a centrifugal pump, but also rely on the rotation of the impeller to obtain centrifugal force, until the gas density to mechanical vacuum pump working range and was removed, and gradually get a high vacuum. In the multi-stage pump body with the right amount of water as the working fluid. When the impeller rotates clockwise, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed circle of approximately equal thickness depending on the shape of the pump chamber. The inner surface of the lower part of the water ring just tangential to the impeller hub, the upper inner surface of the water ring just in contact with the blade tip, in fact, the blade has a certain depth of insertion in the water ring. At this moment, a crescent-shaped space is formed between the impeller hub and the water ring, and the space is divided into a plurality of small cavities equal to the number of the blades by the impeller. If the lower part of the impeller 0 ° as a starting point, then the impeller 180 ° before the rotation of the small chamber volume from small to large, and the end of the suction port communicating, when the gas is inhaled, when the inhalation end of the small cavity When the impeller continues to rotate, the small cavity becomes smaller and the gas is compressed; when the small chamber communicates with the exhaust port, the gas is discharged outside the pump. Through the above introduction, it can be found that the horizontal multistage centrifugal pump is the use of changes in the pump volume to achieve suction, compression and exhaust, horizontal multistage centrifugal pump of this kind of working principle is more suitable for China's industrial work Requirements and requirements. With the increasing demand for horizontal multistage centrifugal pumps in the market, horizontal multistage centrifugal pumps are bound to face greater opportunities and challenges.
