1.The stator and rotor of the submersible motor is made of Y type, Y2 type electric motor and rotor, which is convenient to reduce the cost and expand the production scale, which is suitable for mass production. At the same time to the user's selection, matching, maintenance has brought great convenience.
2.According to different purposes and use occasions, the use of different impeller structure. The anti winding and non blocking performance, passing ability, high efficiency and energy saving and has a unique design of single and double channel impeller blades or closed impeller etc..
3.Commonly used single volute spiral type, bottom water, lateral drainage channel, large area.
4.Between the impeller and the volute chamber is equipped with a removable wear-resistant sealing ring, to ensure the pump running at maximum efficiency.
5.For a higher lift pump, the impeller is provided with a back seal. Its role is to reduce the pressure of the liquid pump seal cavity before. So as to balance the axial force and prevent the impurity particles into the sealing device, improve the service life of the sealing.
6.Between the motor and the pump head is equipped with a double end mechanical seal, for a larger power submersible sewage pump can also be used two single end face mechanical seal series installation. Sealing materials are tungsten carbide, silicon carbide, carbide, ultra - wear - resistant seal, or other materials such as graphite.
7.Power is above 15kW, equipped with self cooling system, back blades to flow into the stator chamber peripheral circulating cooling volute chamber, pump can ensure the minimum water level in the pool or dry running normally. The wiring cavity also has water probe, when the main cable and control cable fault Water Leakage or for other reasons, the probe signal, the control system implemented to protect the pump.
8.Oil room cooling and lubricating mechanical seal. And the motor cavity and the pump part of the isolation, there is no electrode protection - oil-water probe, when the transmission medium into the oil chamber when the electrode signal, by the control system, inform the management personnel in a timely manner. At the same time, the control system closely monitors the leakage.
9.Motor cavity Water Leakage detector is installed on the lower end of the float switch, a signal when the medium to be delivered into the motor cavity, the control system implemented to protect the pump.
10. Motor stator with F insulation (155 degrees C), inside the thermal overload protection device, while the installation of the bearing at the same time also set thermal overload protection, can prevent motor overheating and overload, bearing super temperature, etc..
11.Also leakage, overload and lack of a over temperature protection device with other submersible sewage pump.
