Centrifugal pump is a pump that uses the centrifugal force generated by the rotation of the impeller to transport liquid. Its basic working principle is: when the centrifugal pump is started, the pump shaft drives the impeller to rotate at high speed, forcing the liquid pre-filled between the blades to rotate with it. Under the action of inertial centrifugal force, the liquid is thrown from the center of the impeller to the outer edge of the impeller, and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing, thereby realizing the transportation of liquid.
The working principle of the centrifugal pump is that when the centrifugal pump is started, the pump shaft drives the impeller to rotate at high speed, forcing the liquid to rotate in the impeller. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the periphery, the pressure increases and flows into the pump casing. As the flow channel in the pump casing gradually expands, the flow rate of the liquid slows down, and most of the kinetic energy is converted into pressure energy, and finally flows into the discharge pipe from the discharge port with a higher static pressure.
The application of centrifugal pumps is also very extensive. They can be used in municipal water supply, from water plants to transport treated clean water to water storage facilities in various areas, and then to secondary pressure pump stations to lift water to high-rise residential buildings. Centrifugal pumps rely on stable flow, appropriate head and efficient operation characteristics to ensure that urban residents can use clean and sufficient tap water anytime and anywhere to meet the full range of water needs in daily life. It also plays a very important role in industrial fields such as chemical and petroleum. In chemical companies, the transportation of various corrosive raw materials and finished liquids requires centrifugal pumps to have material properties that are resistant to strong acids and alkalis; in the process of oil extraction and refining, centrifugal pumps undertake the heavy tasks of crude oil extraction and oil product transportation, and need to cope with high temperature, high pressure and flammable and explosive environments; the metallurgical industry uses centrifugal pumps to circulate water for the cooling system to ensure the normal operation of production equipment and help all aspects of industrial production to operate efficiently.
