What is the relationship between centrifugal pump and slurry pump?
First of all, the relationship between centrifugal pumps and slurry pumps is explained, and then the principle of slurry pumps is naturally clear. The concept of centrifugation is based on the principle of the pump. There are many types 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. It is the process of pressurizing the conveying medium through the action of centrifugal force. In addition, there are common types including the screw principle and plunger principle, which can be divided into pumps 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 divides from the conveying medium. As the name implies, the slurry pump delivers a mixture of solid particles containing dross and water. But in principle, slurry pumps are a type of centrifugal pump. 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 direction of movement, thereby 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 center to the edge of the impeller, and flows out of the impeller at a very high speed, enters the extrusion chamber, and is discharged through the diffusion pipe. This process is called pressure water process. At the same time, because the fluid in the center of the impeller flows to the edge, a low pressure region is formed in the center of the impeller. When it has sufficient vacuum, the fluid enters the impeller through the suction chamber under the pressure of the suction end (usually atmospheric pressure). This process is called Water absorption process. Due to the continuous rotation of the impeller, the fluid is continuously discharged and sucked in, forming a continuous work. The working process of centrifugal pumps (including slurry pumps) is actually a process of energy transfer and conversion. It transfers the mechanical energy of the motor at high speed through the blades of the pump and converts it into pressure energy and kinetic energy of the pumped fluid.

Slurry pump China Do Pump, Wear and hydraulic performance issues: In order to reduce wear, the velocity of rotating parts and fluids should be kept low enough. Slurry pump material AO5) Pump body hard alloy lining or elastic lubricating material section thickness should be increased To meet the needs of actual operation. The radial section of the impeller is generally close to rectangular, and the front end seal is used on the vertical plane to reduce the axial rotation area. The pump casing of the slurry pump (material AO5) is generally designed as a semi-spiral or ring shape, so that The amount of wear is kept small within the range. When it is necessary to transport large particles of solids, the width of the built-in closed impeller is usually large, and the number of blades is also reduced to 2-3. There will be varying degrees of reduction. The impeller and volute materials of the slurry pump (material AO5), such as rubber, neoprene, polyurethane resin and other elastic materials, are generally used where the impeller outlet speed is lower than 23m / s, which can improve the effective cavitation residual of the pump the amount. The slurry pump can be widely used in mining, power, metallurgy, coal, environmental protection and other industries to transport slurry containing abrasive solid particles. Such as metallurgical mine plant slurry transportation, thermal ash removal in thermal power plants, coal washing plant coal slurry and heavy media transportation, dredging rivers, river dredging, etc. China Do Pump's high-quality products and first-class after-sales services have won praise from customers across the country!
