How the submersible pump works

There are several kinds of submersible pump, the motor in the line with oil contamination and water invasion and is dry, must look at the instruction before use, can't make a mistake, not for a long time, must have to get the impeller before use, or you'll burn bag because of the need not stuck for a long time.Before opening the pump, the suction pipe and pump must be filled with liquid.After open pump, high-speed rotating impeller, the liquid with the blades rotate together, in under the action of centrifugal force, fly away from the impeller to injection, injection of the liquid in the pump shell gradually spread of indoor speed slow, pressure increase gradually, and then from the pump discharge, the discharge pipe flow.At this point, in the center of the blade due to liquid was dumped into the surrounding formation is no air and no liquid vacuum low pressure area, fluid in the pool liquid under the action of atmospheric pressure on surface of the pool, the suction pipe into the pump, the liquid is continuously from the liquid pool was sucking up and continuously from the discharge pipe flow.
