To understand centrifugal pumps, you must first know the concept of centrifugation. What is centrifugation? Centrifugal is actually the manifestation of the object inertia.For example, the water droplets on the umbrella, when the umbrella slowly turns, the water droplets will follow the umbrella rotation, this is because the friction between the umbrella and the water droplets as the centripetal force to the water droplets. However, if the umbrella rotates faster, the friction is not enough to make the water drop in circular motion, then the water drop will move away from the umbrella to the outer edge, just as a rope is used to carry the circular motion of the stone, and if it is too fast, the rope will Disconnected, the rocks will fly out. This is called Centrifugal. Centrifugal pump is designed according to this principle.High-speed rotation of the impeller blades to rotate the water, the water thrown, so as to achieve the purpose of delivery. Centrifugal pump has many kinds.It can be divided into civil and industrial pumps from the use, from the transmission medium can be divided into water pump, impurity pump, corrosion-resistant pump.
