The working principle of petrochemical pump

Petrochemical pump is widely used in various fields of chemical industry, the chemical industry, metallurgy, pharmacy, to foil etc, all have important applications. Petrochemical pump is conveying material by centrifugal force, the working principle of the following chemical pump before work, pump body and feed pipe line must be stinking liquid into a vacuum, when the fast rotating impeller blade makes liquid rapidly rotating, rotating liquid material under the action of centrifugal force, fly away from the impeller, pump in the water is thrown, the center of the impeller part form the vacuum area. Under the action of liquid materials in the atmospheric pressure through the pipe network pressure to the feed tube. So circulates, can realize continuous transmission. Before starting the in chemical pump, pump shell filled with liquid to be delivered; After the start, start, by axis high-speed rotating impeller, the blade between the liquid must also along with the rotation. Under the action of centrifugal force, the liquid from the impeller center was thrown to the outer edge and gain energy, leaving the impeller outer edge at high speed into the volute pump shell. Liquid in the volute, due to the widening of flow reduction, can and will be part of the kinetic energy into static pressure, finally to high pressure into the discharge pipe, sent to the need to place. Liquid flow to the outer edge by the impeller center, formed the certain vacuum, in the center of the impeller by the pressure on the top of the holding tank liquid level is greater than the pump pressure, at the entrance of the liquid was continuous pressure into the impeller. Visible, as long as constantly rotating impeller, liquid will be overtaken by suction and discharge.
