What is the working principle of centrifugal pumps? What are the uses?

In many fields such as industrial production and economy, there is a need to transport or pressurize liquids, and the machinery that can accomplish these tasks is called a pump, and the pump that acts centrifugally is called a centrifugal pump. How does the centrifugal pump work? Let's learn about its working principle!

The centrifugal pump works by using the impeller to rotate and make the water centrifugal movement. Before starting the pump, the pump casing and suction pipe must be filled with water, and then start the motor, so that the pump shaft drives the impeller and water to do high-speed rotational movement, water centrifugal movement, was thrown to the outer edge of the impeller, through the worm-shaped pump casing of the flow channel into the pump pressure water line.

The main working principle of centrifugal pump.

(1) The impeller is driven by the pump shaft to rotate and do work on the fluid located between the blades, and the fluid is centrifuged and thrown to the periphery by the center of the impeller. When the fluid reaches the outer circumference of the impeller, the flow rate is very high.

(2) the pump casing collects the liquid thrown from each vane, these liquids flow in the casing in the direction of the worm-shaped channel gradually expanding, so that the kinetic energy of the fluid into static pressure energy, reduce energy loss. So the role of the pump shell is not only in the collection of liquid, it is an energy conversion device.

(3) Liquid suction principle: rely on the impeller high-speed rotation, forcing the center of the impeller to be thrown away at a very high speed, thus forming a low pressure in the center of the impeller, the liquid in the low tank is therefore constantly sucked up.

Because of its simple structure, stable performance, convenient maintenance, easy operation and strong adaptability, centrifugal pump can be widely used in electric power, metallurgy, coal, building materials and other industries to transport slurry containing solid particles. Such as thermal power plant hydraulic ash removal, metallurgical ore dressing plant slurry conveying, coal washing plant coal slurry and heavy medium conveying, etc.

Taizhou Ouke Technology Co.,Ltd. is a new type of enterprise integrating R&D, production and sales. Since its establishment, it has been dedicated to the R&D and production in the field of pump and pump system solution automation control system. The above-mentioned product - centrifugal pump, one of the company's special products, is made of high-quality materials and treated with special anti-rust electrophoresis to greatly extend the service life of the pump.
