Submersible slurry pump
Slurry pump is a centrifugal pump from the working principle. It conceptually refers to a machine that converts the energy of solid and liquid mixed media by the action of centrifugal force (rotation of the impeller of the pump) to convert electrical energy into A device for the kinetic and potential energy of a medium. Mainly used in: mining, power plants, dredging, metallurgy, chemical, building materials and petroleum industries. The name of the slurry pump is a centrifugal pump that is divided from the perspective of the conveying medium. In addition, the slurry pump can be divided into different types from different angles. In addition to pumping water, the pump can also pump gas, solid, solid-liquid mixture - mineral mud slurry! Pump power consumption accounts for a large proportion of the country's total electricity. Pump energy conservation has an important impact on the national economy. Pumps not only play an active role in the energy-saving process, but also play an important role in the thermal power generation emission reduction process. The slurry pump not only saves 4%-8% energy compared with similar products, but also contributes to the atmosphere from the smog "claw".
A pump suitable for transporting suspended solids in a liquid (water) is generally referred to as a slurry pump. It is currently one of the indispensable equipments in the process of mineral processing and coal preparation. The slurry pump can be divided into single-stage/multi-stage, single-suction/double-suction, cantilever, horizontal/vertical and horizontal/vertical combination of pump casing according to different principles. As shown in the figure, the basic structure is impeller. The pump casing, the pump shaft, the bearing and the bracket are composed of the electric motor, the opposite wheel or the tape wheel coupling, the wear parts further include the lining bushing, etc., and the sealing component includes the shaft seal, the auxiliary impeller, etc. The parts include brackets, etc., but the internal principle is the same. When the impeller rotates rapidly, the blades cause the medium to rotate quickly. The rotating medium flies out of the impeller under the action of centrifugal force. After the medium in the pump is thrown, the impeller The central portion forms a vacuum region, and the medium is pressed into the feed tube through the pipe network under the action of atmospheric pressure (or water pressure). In this way, continuous feeding can be achieved to achieve the head and flow required by the process design. Of course, the feeding method is currently more indented, that is, the filling level is higher than the feeding tube, and the step of pouring water from the upper water pipe or the pump casing to the inside can be subtracted.
First, let's talk about the relationship between the centrifugal pump and the slurry pump, and then the principle of the slurry pump is naturally clear. The concept of centrifugation is in terms of the pump principle. There are many types of pumps, which can be divided into dozens of categories depending on the angle. The centrifugal pump is divided from the working principle of the pump, and the centrifugal force is used to achieve the process of pressurizing the conveying medium. There are also common types including the principle of the screw, the principle of the plunger, etc., which can be divided into pumps different from the principle of centrifugation. After talking about the centrifugal pump concept, and then 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 delivers a mixture of solid particles and water containing dross. But in principle, the slurry pump is a kind of centrifugal pump. The main working components of the centrifugal pump are the impeller and the casing. The impeller device in the casing is located on the shaft and is 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, i.e., the blade performs work on the fluid in its direction of motion, thereby forcing the pressure potential 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 tube. This process is called a water pressure process. At the same time, since 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 sufficient vacuum, the fluid enters the impeller through the suction chamber under the pressure of the suction end (generally atmospheric pressure). Water absorption process. Due to the continuous rotation of the impeller, the fluid is continuously discharged and sucked to form a continuous operation. The working process of a centrifugal pump (including a slurry pump) 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 the pressure and kinetic energy of the pumped fluid.
The main advantage:
●Good hydraulic performance
● low wear rate
●The flow path is wide
●Good anti-blocking performance
● Excellent cavitation performance
