First, centrifugal force.
The slurry pump produces centrifugal force through the rotation of the impeller, which separates the solid particles in the mixture and forms dense slurry. Solid particles are mixed in the impeller. In the process of impeller rotation, due to the centrifugal force, solid particles are forced to move outward across the centrifugal force field and finally discharged from the pump body.
Second, the pressure change effect.
Under the action of centrifugal force, after the solid particles are separated, the remaining liquid is pushed to the outlet of the pump body. Then, due to the reduced diameter design of the pump body, the flow rate of the liquid will increase, thus increasing the pressure of the liquid. When the liquid passes through the outlet of the pump body, due to the sudden drop of pressure, it is difficult for solid particles to mix with the liquid again, thus being discharged from the pump body.
Third, the workflow.
Start the pump: Before working, it is necessary to start the slurry pump to make the impeller start to rotate.
Pump in the mixture: convey the mixture containing solid particles and liquid to the inlet of the slurry pump.
Separation of solid particles: Due to the centrifugal force, the slurry pump can separate the solid particles in the mixture to form slurry.
Discharge of mud: under the action of pressure change, mud-like substances are pushed to the outlet of the pump body and discharged from the pump body.
Reciprocating: According to the work needs, the mixture can be continuously transported to the slurry pump, and the slurry pump can be transported circularly.
To sum up, the working principle of slurry pump is based on centrifugal force and pressure change. Centrifugal force is generated by the rotation of the impeller, so that the solid particles in the mixture are separated, and the slurry is discharged from the pump body through pressure change. In industrial applications, slurry pumps are often used to transport mixtures containing large particles and high-concentration impurities, which have the characteristics of wear resistance, anti-clogging, strong bearing capacity and simple maintenance.
