How Does The Slurry Pump Work?

The slurry pump can be widely used in mining, power plant, dredging, metallurgy, chemical industry, building materials and petroleum, and other industries. Slurry pumps can also be divided into different types from different angles. In addition to pumping water, the water pump can also pump gas, solid, solid-liquid mixture – mineral powder slurry. Slurry pumps not only play an active role in energy saving, but also play an important role in the emission reduction process of thermal power generation. The slurry pump not only saves 4%-8% more energy than similar products.

How does the slurry pump work?

The main working parts of a 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 vanes in the impeller force the fluid to rotate, that is, the vanes do work on the fluid in the direction of its motion, 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 high speed, enters the pressure chamber, and is discharged through the diffuser. This process is called the water pressure process.

At the same time, because the fluid in the center of the impeller flows to the edge, a low-pressure area 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 the Water absorption process. Due to the continuous rotation of the impeller, the fluid is continuously discharged and sucked to form 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 high-speed rotation of the motor through the blades of the pump and converts it into the pressure energy and kinetic energy of the pumped fluid.
