Structural feature
1.Special submersible motor
The whole series of motors are of H-class insulation,temperature resistance reaching 180ºC,protection level is IP68, low energy consumption,low temperature rise,and high stability,compared with ordinary motors, increase heat resistance by 60 degrees celsius, extend the life, and the wiring chamber is sealed and separated from the stator and rotor of the motor, which brings double insurance.The motor bearing adopts the auxiliary oil tank structure, which increase the bearing service life.
2.Electric pump protection system
The motor has a number of built-in warning sensors,including the leakage in the wiring chamber,,the motor cavity and the oil chamber, and the temperature rise of the bearding and the motor coil. The motor is equipped with water leakage monitoring,and the oil chamber is equipped with oil mixed water probes.There is comprehensive monitoring of motor operating conditions.
3.Impeller,volute
The products adopt three-dimensional flow theory design, CFD calculation simulation,non-blocking,non-overload design, and are of high efficiency, wide efficient range,low energy consumption, and adopt double-flow channel non-blocking impeller.The passage of the pump body is wide, so the solids are easy to pass, and the fibers are not easy o entangle. The impeller is strictly balanced to minimize vibration and maximize the life of bearings and mechanical seals.
4.Cable anti loose sealing system
The cable outlet adopts special structure,which eliminates water leakage, electricity leakage,short circuit,and stator coil burnout caused by accidental factors such as artificial pulling,broken cable jacket, and cable aging,which effectively reduces the probability of failure caused by water in the upper part of the whole machine
5.Cooling system
The motor uses four sides to contact with water or air,which greatly improves its heat dissipation capacity. The motor bearding housing is in direct contact with water or air,which enhances the heat dissipation capacity of the bearing and greatly increases the service life of the bearing.According to the water level,cooling-jacket cooling system is provided to ensure that the motor can continue to run when it breaks the surface of water
6.Sealing system
The product adopt patented structure, double sealed chamber structure,three sets of mechanical seal are used in the pump,and a buffer chamber is added.This greatly increases the reliability of the seal and completely guarantees the reliable operation of the products.The mechanical seal adopts integrated installation.
