The so-called
Slurry Pump is a kind of centrifugal pump with high efficiency and relatively strong performance, which has evolved in recent years due to the large particles of material transportation, and is currently one of the indispensable equipment in each process of coal preparation plant.
Working principle of
slurry pump The slurry pump belongs to a kind of centrifugal pump from the physical principle, and conceptually refers to a mechanical device that increases the energy of the solid and liquid mixed medium by means of centrifugal force (rotation of the
Impeller of the pump), and converts electrical energy into the kinetic energy and potential energy of the medium. The name of the slurry pump is a centrifugal pump divided from the point of view of the conveying medium.
First of all, the relationship between the centrifugal pump and the slurry pump is described, and then the principle of the slurry pump is naturally clear. The centrifugal concept is derived from the pump. There are many kinds of pumps, which can be divided into dozens of categories according to different angles. Centrifugal pump is divided from the working principle of the pump, which is the process of pressurizing the conveying medium through the effect of centrifugal force. In addition, there are common types including the screw principle, the plunger principle, etc., can be divided into pumps different from the centrifugal principle. After saying the concept of centrifugal pump, say slurry pump, slurry pump is from another Angle to divide the pump, that is, from the transport medium to divide. As the name suggests, the slurry pump delivers a mixture of solid particles containing slag and water. But in principle, the slurry pump belongs to a centrifugal pump. So these two concepts are clear.
The main working parts of the centrifugal pump are the impeller and the casing, and 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 blade in the impeller forces the fluid to rotate, that is, the blade does work on the fluid along its direction of movement, thus forcing the pressure potential energy and kinetic energy of the fluid to increase. At the same time, under the action of inertial force, the fluid flows from the middle to the edge of the impeller, and flows out of the impeller at a very high speed, into the extrusion chamber, and then discharged through the diffusion tube, this process is called the pressure water process. At the same time, because the fluid in the middle of the impeller flows to the edge, a low pressure area is formed in the middle of the impeller, when it has enough vacuum, under the action of the suction end pressure (generally atmospheric pressure), the fluid enters the impeller through the suction chamber, this process is called the water absorption process. Due to the continuous rotation of the impeller, the fluid is continuously discharged and inhaled, forming 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 rotating at high speed through the blade of the pump and converts it into the pressure energy and kinetic energy of the pumped fluid.
