Chemical pump relies on centrifugal force to transport material, the working principle is as follows: Chemical pump Before work, the pump body and feed pipe must be full of liquid line into a vacuum state, when the impeller rotates rapidly, the blade to promote the liquid to rotate quickly, the rotating liquid Under the action of centrifugal force, the material flies from the impeller. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. Liquid material in the atmospheric pressure through the pipe network pressure into the feed tube. This cycle endless, we can achieve continuous delivery. Before the chemical pump is started, the pump casing is filled with the liquid to be transported. After starting, the impeller is driven by the shaft to rotate at a high speed, and the liquid between the blades must also rotate along with it. Under the action of centrifugal force, liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller to enter the scroll casing at a high speed. In the volute, the liquid due to the gradual expansion of the slowing down, but also part of the kinetic energy into static pressure, and finally to a higher pressure into the discharge pipe, to the required place. When the liquid flows from the impeller center to the outer edge, a certain vacuum is formed in the center of the impeller. Since the pressure above the liquid level in the sump is greater than the pressure at the inlet of the pump, the liquid is continuously pressed into the impeller. Visible, as long as the impeller constantly rotating, the liquid will be continuously inhaled and discharged.
