The working principle of the pump
Jul 23, 2018

Impeller installed in the pump shell, and fastening in the pump shaft, the pump shaft is directly driven by the motor. The pump shell has a liquid straw in the center. The liquid is entered into the pump by the bottom valve and the suction tube. The liquid discharge outlet of the pump casing is connected with the discharge pipe.

Before the pump starts, the pump shell is filled with the liquid that is transported, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate. Under the action of centrifugal force, the liquid from the impeller center is thrown to the outer edge and to obtain energy, to high-speed off the outer edge of the impeller into the volute pump shell. In the volute, the liquid due to the gradual expansion of the flow channel deceleration, but also the partial kinetic energy into static pressure energy, and finally to the higher pressure into the discharge pipe, sent to the need for a place. Liquid from the impeller Center to the outer Rim, the impeller in the center formed a certain vacuum, because the tank above the liquid surface pressure than the pump inlet pressure, the liquid is continuously pressed into the impeller. Visible, as long as the impeller constantly rotating, the liquid will continue to be inhaled and discharged.

The principle of the linear pump is different with any other pump, is the use of magnetic levitation principle and spiral ring hydrodynamic structure to achieve liquid propulsion, that is, cancel the shaft, cancel the shaft connection, cancel the shaft seal structure. After starting the current into the magnetic field, magnetic force driving spiral ring operation, that is, spiral ring lifting liquid forward. 、、
