The characteristics and applications of the submersible pump

Submersible pump is a very versatile tool in water treatment. Unlike ordinary water pump it works under water, and water pump work mostly on the ground. Open 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. Place 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.

Submersible pump motor and pump water machine straight league one into the water, it is suitable for the extraction of groundwater from a deep well, can also be used for rivers, reservoirs, canals and other water engineering; Mainly used for farmland irrigation and plateau mountainous area with water, for cities, factories, railways, mines, construction site water supply and drainage. Motor, pump body, run into the water, safe and reliable. Tube, Yang pipe has no special requirements for well (i.e., the steel tube well, grey tube well, doi, etc all can use; under pressure licensing, steel pipes, rubber hose can be used for Yang pipe, plastic pipe, etc).

Submersible pump installation, convenient in operation and maintenance of the method is simple, cover an area of an area small, do not need to build the pump room. Simple structure, saves the raw material. Submersible pump compact structure, and only when the work will be in the water pump can be start work, simple installation, convenient movement. Due to its simple structure, small volume, easy to use, so got rapid development. Submersible pump design starting point is “no jams, no winding”, some models with a torn institutions or cutting device, can carry sewage long fiber, bags, such as tear out the back.

Submersible pump of the disadvantage is that the pumping of solid medium is more soft, sediment concentration in water limited within 3%, large sediment concentration, easy damage sealing, once the motor inlet, bearing, winding insulation damage, leading to motor burn down. In addition, only a single pump submersible sewage pump, the large flow, lift generally very low, cannot satisfy some mine of high head, low flow requirements.
