The working principle of a slurry pump impeller is based on centrifugal force. Its core function is to convert electrical energy into the kinetic energy and pressure energy of the slurry through high-speed rotation of the impeller, thereby achieving the transport of solid-liquid mixed media (slurry).
Suction Process
When the impeller rotates, a low-pressure zone (approximately a vacuum) forms in the central area. Under the action of external atmospheric pressure or water pressure, the slurry is pushed into the pump, continuously replenishing the impeller inlet.
Energy Transfer and Discharge Process
As the slurry rotates at high speed with the impeller, it is flung from the center of the impeller to the outer edge under the action of centrifugal force. The slurry gains high-speed kinetic energy and enters the pump casing (usually volute). As the flow passage area gradually enlarges, the flow velocity decreases, and part of the kinetic energy is converted into static pressure energy, discharging at high pressure.
Continuous Transport
The impeller keeps rotating, forming a stable suction-discharge cycle, achieving continuous transport of the slurry.
