1.Submersible pump
Submersible pump is a very wide range of water treatment tools. The difference is that it works in the water, while the pump works mostly on the ground.
Submersible pump working principle: before the pump, the suction pipe and the pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves theliquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube.
At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube. The basic parameters of submersible pumps including flow, head, pump speed, supporting power, rated current, efficiency, diameter and so on submersible pump is the main purpose and scope including the construction schedule, water and agricultural irrigation, industrial water cycle, urban and rural drinking water supply, and even disaster relief and so on
2.Centrifugal pump
To say what is centrifugal. Centrifugal is actually the performance of the inertia of the object. For example, the water droplets on the umbrella, when the umbrella slowly rotating, water droplets will follow the umbrella rotation, which is due to the friction between the umbrella and water droplets as a result of the force to the water droplets. But if the umbrella turns to speed, the friction is not enough to make the water drop in the circle, then the water drop will move away from the umbrella. Like a piece of rope pulling the stones to do a circular motion, if the speed is too fast, the rope will be broken, the stones will fly out. This is called centrifugation.
Centrifugal pump is designed according to this principle. High speed rotation of the impeller blades to drive water rotation, the water thrown out, so as to achieve the purpose of conveying. There are many kinds of centrifugal pump. From the use can be divided into civil and industrial use of pumps, from the delivery of the medium can be divided into water pump, impurity pump, corrosion resistant pumps, etc.. The basic structure of the centrifugal pump is composed of six parts, namely: impeller, pump body, pump shaft, bearing, seal ring, stuffing box.
