Centrifugal pumps have various forms such as vertical, horizontal, single-stage, multi-stage, single-suction, double-suction, and self-suction. Its main working principle is as follows: Centrifugation is a manifestation of the inertia of an object. For example, the water droplets on an umbrella, when the umbrella rotates slowly, the water droplets will follow the umbrella to rotate. This is because the friction between the umbrella and the water droplets acts as a centripetal force for the water droplets.
But if the umbrella rotates faster, this friction is not enough to make the water droplets move in a circle, then the water droplets will move away from the umbrella and move toward the outer edge. It is like using a rope to pull a rock in a circular motion. If the speed is too fast, the rope will break and the rock will fly out. This is the so-called centrifugal centrifugal pump is designed according to this principle. The high-speed rotating impeller blades drive the water to rotate and throw the water out, so as to achieve the purpose of conveying.
