First, tell us about the relationship between the centrifugal pump and the slurry pump, and then the principle of the slurry pump is naturally clear. The centrifugal concept is based on the original pump. There are many kinds of pumps, which can be divided into dozens of categories according to different angles. The centrifugal pump is divided from the working principle of the pump, which is the process of pressurizing the conveying medium through the action of centrifugal force. In addition, there are common types including screw principle, plunger principle, etc. which can be divided into pumps that are different from the centrifugal principle. After talking about the centrifugal pump concept, let’s talk about the slurry pump. The slurry pump divides the pump from another angle, that is, it is divided from the conveying medium. As the name implies, the slurry pump transports a mixture of solid particles containing scum and water. But in principle, the slurry pump is a kind of centrifugal pump. In this way, these two concepts will be made clear. The main working parts of the centrifugal pump are the impeller and the casing. The impeller device in the casing is located on the shaft and connected with the prime mover to form a whole. When the prime mover drives the impeller to rotate, the blades in the impeller force the fluid to rotate, that is, the blades do work on the fluid along its moving direction, thereby forcing the pressure potential and kinetic energy of the fluid to increase. At the same time, the fluid flows from the center to the edge of the impeller under the action of inertial force, and flows out of the impeller at a high speed, enters the extrusion chamber, and then is discharged through the diffuser. This process is called the pressurized water process. At the same time, because the fluid in the center of the impeller flows to the edge, a low-pressure zone is formed in the center of the impeller. When it has enough vacuum, under the action of the suction end pressure (usually atmospheric pressure), the fluid enters the impeller through the suction chamber. This process is called Water absorption process. Due to the continuous rotation of the impeller, the fluid is continuously discharged and sucked in to form continuous work.　　 The working process of centrifugal pumps (including slurry pumps) is actually a process of energy transfer and transformation. It transfers the mechanical energy of the motor at high speed through the blades of the pump and converts it into the pressure energy and kinetic energy of the pumped fluid.
