A submersible slurry pump is a kind of centrifugal pump from the principle of physics. Conceptually, it refers to a machine that adds energy to solid and liquid mixed media through the effect of centrifugal force (the rotation of the pump's impeller) and converts electrical energy into a device for the kinetic and potential energy of a medium. The name of the submersible slurry pump is a centrifugal pump that is distinguished from the point of view of the conveying medium.

 

The connection between the centrifugal pump and the submersible slurry pump

Firstly describe the connection between the centrifugal pump and the submersible slurry pump, and then the principle of the submersible slurry pump is naturally clear. The concept of centrifugation is from the pump itself. There are many types of pumps, and dozens of categories can be distinguished according to different viewpoints. The centrifugal pump is distinguished from the working principle of the pump. It is the process of pressurizing the transport medium through the effect of centrifugal force. In addition, there are common varieties including the screw principle, plunger principle, etc. which can distinguish pumps different from the centrifugal principle. After talking about the centrifugal pump concept, let's talk about the submersible slurry pump. The submersible slurry pump distinguishes the pump from another point of view, that is, the transport medium. As the name implies, the submersible slurry pump transports a mixture of solid particles containing dross and water. However, in principle, the submersible slurry pump is a type of centrifugal pump. In this way, the two concepts are made clear.

 

 

How does the Centrifugal pump work？

The main working parts of a centrifugal pump are the impeller and the casing. The impeller equipment inside the casing is located on the shaft and connects 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 blade does work on the fluid along its direction of movement, and then forces the pressure potential energy and kinetic energy of the fluid to be added. At the same time, under the effect of inertial force, the fluid flows from the center to the margin of the impeller, flows out of the impeller at a high speed, enters the extrusion chamber, and is discharged through the dispersion pipe. This process is called the pressure water process. Together, because the fluid in the center of the impeller flows to the margin, a low-pressure region is formed in the center of the impeller. When it has a satisfactory vacuum, the fluid enters the impeller through the suction chamber under the effect of the pressure at the suction end (usually atmospheric pressure). This process is called the Water absorption process. Because the impeller rotates in succession, the fluid is continuously discharged and sucked in, which constitutes a continuous operation.
