1、 Overview:
The intelligent submersible pump is a new type of pump product developed by our factory based on market demand. The structural design of the fully intelligent system is a historical blank for this type of pump in China. *Solved the disadvantage of high axial tension and easy leakage of mechanical seals in high head situations of single suction submersible electric pumps. Due to the use of mature technology for the installation structure of double suction submersible electric pumps, both mobile installation and rail fixed installation can be adopted Easy to install, maintain, and use. It has unique advantages in the disposal of solid particles and long fiber waste.
The performance indicators of the intelligent submersible pump have met the national standards and regulations. After its launch on the market, the product has been welcomed and praised by a large number of users for its * effectiveness, reliable performance, and stable quality. This pump is divided into two series: clean water and sewage, and these two series are further divided into three categories: ordinary type, with external circulation cooling water type, and automatic mixing type.

3、 Product features:
1. The intelligent submersible pump oil chamber is equipped with an oil-water probe. When the mechanical seal on the pump side is damaged, water enters the oil chamber and the probe generates a signal to protect the pump
2. Intelligent submersible pumps can meet the requirements for high head applications, as the mechanical seals operate under negative pressure and have higher stability.
3. The double suction structure is used to lower the suction water level. Due to the use of a double suction double channel single volute structure, the motor no longer has axial tension, reducing and balancing radial forces, greatly improving the service life of the pump by three times and increasing the efficiency by 15%.
4. The pump equipped with an external circulating water device can work continuously for a long time in low water level situations A pump equipped with a self stirring impeller with self stirring function It can stir the water in the pool to mix sewage and pollutants and discharge them with the pump.
5. The intelligent submersible pump adopts a large channel anti clogging component design, greatly improving the ability of pollutants to pass through, and can effectively pass through shorter fiber materials and solid particles with smaller diameters.
6. The mechanical seal adopts a dual channel series seal, made of hard and corrosion-resistant tungsten carbide, which has the characteristics of durability and wear resistance, and can ensure the safe operation of the pump for more than 8000 hours.
7. Intelligent submersible pump is a clever combination of submersible motor and double suction pump, which not only has the function of submersible electric pump, but also has the special performance of efficient and smooth operation of double suction pump.
8. The double rail automatic coupling safety system has brought great convenience to the installation and maintenance of pumps, and people do not need to enter and exit the sewage pit for this purpose.
9. The float switch can automatically control the stop and start of the pump according to the required water level changes, without the need for a dedicated person to supervise.
10. There are two installation methods: fixed automatic coupling installation and mobile installation, which can meet different usage scenarios.
4、 Application conditions:
1. The medium temperature shall not exceed 60 ℃, the density shall not exceed 1.3kg/L, and the pH value shall be within the range of 5-9.
2. For submersible pumps without cooling circulation systems, the motor must be submerged by more than half to avoid burning out the motor.
3. In general, the pump must be used within the range of head to ensure that the motor is not overloaded. If it needs to be used within the full head range, it should be specified separately when ordering for the manufacturer to manufacture.
4. The actual head used must be close to the head indicated on the nameplate. If the actual head used is too low, it may cause overcurrent and burn out the motor.
5、 Purpose:

2. Urban sewage treatment plant drainage system.
4. Civil air defense system drainage station.
5. Wastewater discharge from hospitals and hotels.
6. Municipal engineering and construction sites.
8. Rural biogas digesters for farmland irrigation.
9. The water supply system of a water plant.
