Abstract
The invention relates to a submersible pumping device comprising a pump and a drive device of the pump. The submersible electric pump for a well comprises a submersible motor and a submersible pump which are mutually connected; a water suction mouth is arranged between the submersible pump and the submersible motor; and the other end of the submersible pump is connected with a water delivery pipeline. The submersible electric pumping is mainly used for extracting underground water from the deep well and can also be used for water engineering for people and animals in an oil field, a plateau and a mountainous area. The submersible pumping device has the characteristic that the motor and a water pump are assembled together and are dived into water to work and has the benefits that a continuous duty working mode is adopted, the axial force is resolved, the reliability of the electric pump is improved, and the operation is convenient.
Description
Technical field
The present invention relates to a kind of pumping installations that comprises pump and drive unit thereof be used to slipping into.
Background technique
Water pump is the machinery of carrying liquid or making the liquid supercharging.It sends mechanical energy or other external energies of prime mover to liquid, liquid energy is increased, be mainly used to carry liquid to comprise water, oil, acid ﹠ alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., the liquid that also can carry liquid, gaseous mixture and contain suspended solids.The technical parameter of weighing pump performance has flow, inhales journey, lift, air horsepower, water-horse power, efficient etc.; Can be divided into the types such as volume water pump, vane pump according to different working principles.Common displacement pump is divided into again diaphragm pump, reciprocating pump, gear pump etc.; Common vane pump is divided into again: the types such as centrifugal pump, axial-flow pump and mixed flow pump.
Summary of the invention
The present invention aims to provide a kind of single suction, multistage centrifugal Submersible Pump.
A kind of Submersible Pump of the present invention comprises interconnective submersible motor and submersible pump, wherein is provided with the water sucking mouth between submersible pump and the submersible motor, and the other end of submersible pump links to each other with water transport pipeline.
Preferably, submersible pump is the single-suction multilevel vertical centrifugal pump.
More preferably, be provided with a rubber bush bearing in every grade of blower inlet casing of submersible pump, be fixedly provided with impeller on the bearing.
Further preferably, check valve is equipped with on the top of submersible pump.
Perhaps preferably, submersible motor is airtight Water wet type three-phase squirrel-cage induction motor.
More preferably, link to each other by coupling between submersible motor and the submersible pump, be provided with single core or three core water-proof cables in the coupling.
Further preferably, submersible motor top is equipped with mazy type and is got rid of sand circle and outside framework oil seal.
The present invention is mainly used in extracting underground water from deep-well, also can be used for people and animals' Hydraulic Projects in oil field, plateau, mountain area.Have the be assembled into one characteristics of the work of pulling the plug of motor and water pump, working method is continuous duty, and it has decomposed axial force, has improved the reliability of electric pump, and is easy to operate.
