As the centripetal force for the water droplets. But if the umbrella turns faster, the friction is not enough to make the water droplets move in a circular motion, then the water droplets will move away from the umbrella to the outer edge. It is like using a rope to pull a rock to make a circular motion. If the speed is too fast, the rope will break and the rocks will fly out.

This is the so-called centrifugal. The centrifugal pump is designed according to this principle. The high-speed rotating impeller blades drive the water to rotate, and the water will be thrown out to achieve delivery. There are many kinds of centrifugal pumps. From the use, it can be divided into civil and industrial pumps, and from the transportation medium can be divided into clean water pumps, impurity pumps, and corrosion-resistant pumps.

The basic structure of a centrifugal pump is composed of six parts: impeller, pump body, pump shaft, bearing, sealing ring, and stuffing box. 1. The impeller is the core part of the centrifugal pump. It has a high speed and a large output. The blades on the impeller play a major role. The impeller must pass a static balance experiment before assembly. The inner and outer surfaces of the impeller are required to be smooth to reduce the friction loss of the water flow. 2.

The Solar Submersible Borehole Pump is also called the pump housing, which is the main body of the water pump. Play a supporting and fixing role, and connect with the bracket for mounting the bearing. 3. The function of the pump shaft is to connect the motor with the coupling to transmit the torque of the motor to the impeller, so it is the main part of the transmission of mechanical energy. 4. The bearing is a component that is sleeved on the pump shaft to support the pump shaft. There are two types of rolling bearings and sliding bearings. Rolling bearings use tallow as a lubricant to refuel properly.
