Submersible electric pump

A type of water pump in which both the impeller of the pump body and the motor driving the impeller are submerged in water for operation. There are two types of water pumps: deep well and working face. The submersible electric pump used in deep wells supplies power to the motor through a cable inserted into the well, eliminating the need for a long shaft transmission. Therefore, it has a compact structure, light weight, and is easy to install, use, and transfer. There is a trend to replace long shaft deep well pumps in areas with power supply, but it is not suitable for water wells with high sediment content and areas without power supply.

The electric motors used in submersible pumps include dry type (all motors are sealed), semi dry type (the stator of the motor is sealed, and the rotor operates in water), oil filled type (the motor is filled with oil to prevent water from entering the winding), and wet type (the motor is filled with water, and both the stator and rotor operate in water). The first three types require sealing and high manufacturing and installation accuracy requirements, so agricultural deep well submersible pumps usually use wet motors. The stator winding is made of water-resistant insulated wires or synthetic resin is poured at the end and slot of the stator winding. The impact of water entering the motor is not significant, and the sealing structure can be greatly simplified, only requiring sand prevention.

Some deep well submersible electric pumps have a lift of up to 1400 meters and a flow rate of 1.4 cubic meters per second.

Magnetic levitation submersible electric pump

The magnetic levitation submersible pump has achieved a major breakthrough in the field of submersible pumps worldwide, effectively solving various drawbacks of traditional submersible pumps, such as low conversion efficiency, high power consumption, limited head, vulnerable bearings, and frequent maintenance. Widely used in the fields of water supply and drainage for industrial and mining enterprises, irrigation for farmland, and water supply for plateau and mountainous areas.

The magnetic levitation submersible pump has changed the manufacturing process of the submersible pump with patented technology, achieving astonishing new levels of conversion efficiency and creating huge energy-saving and consumption reducing benefits.

The magnetic levitation submersible pump has solved the axial force problem that restricts the development of the world's submersible pump field. The head of the submersible pump has been breakthrough improved, filling the market gap of ultra-high head (single machine head design up to thousands) and ultra large flow (high load capacity) submersible pumps; The head and flow curves tend to flatten out. Its conversion efficiency and single machine lift are both in a professional position worldwide.

Magnetic levitation submersible pump is a new generation of submersible pump, which achieves vertical axis magnetic levitation (maintaining high speed under different working conditions), no wear, and extends the service time and maintenance cycle several times, eliminating frequent regular maintenance work. It can operate continuously for tens of thousands of hours, saving maintenance and repair costs.

Experimental data has proven that the conversion efficiency of magnetic levitation submersible pumps exceeds that of traditional submersible pumps. Combining user usage with experimental data and field comparisons, it further proves its energy-saving, world-class conversion efficiency, world-class single machine lift, high load-bearing capacity, large flow rate, inspection and repair free, and long service life characteristics!
