Permanent magnet high-efficiency energy-saving submersible mixer

Permanent magnet high-efficiency energy-saving submersible mixerThe efficiency of the permanent magnet motor is high, and there is no resistance loss in the rotor winding. There is little or almost no reactive current in the stator winding, resulting in low temperature rise during long-term operation of the motor. Compared with ordinary motors, it greatly extends the working time and service life of the motor. Suitable for balancing tanks, nitrification denitrification tanks, sewage treatment and storage tanks in sewage treatment plants, as well as mixing liquids containing suspended solids and solids in industrial processes to prevent sedimentation. The same purpose, usage conditions, performance, and installation dimensions as the ordinary mixer of Nanjing Linuo, not only makes it convenient for new users to install and use, but also eliminates the need to modify the installation system when replacing the super energy-saving mixer in old crowded areas. It can be replaced by purchasing the main unit.

As a submerged device that operates continuously under fully submerged conditions and combines mixing and pushing functions, it can be applied to various types of wastewater treatment by stirring and mixing surrounding water bodies, thereby improving wastewater treatment efficiency. The selection and application of agitators play a crucial role in improving the sewage treatment rate of sewage plants and optimizing sludge discharge. However, currently, submersible agitators generally have low motor efficiency and low rated power factor, which is caused by the application characteristics of the agitator itself. According to preliminary statistics, the energy consumption of stirring and mixing in the sewage treatment process accounts for nearly 20% of the total energy consumption. In recent years, with the rapid development of power electronics technology, new motor control theory, and rare earth permanent magnet materials, high-performance, high power density motors (HPM) are an innovative series of permanent magnet synchronous motors. High efficiency motors are used in submersible agitators to reduce energy consumption in sewage treatment, which has important practical significance for the increasingly scarce energy resources.

Permanent magnet high-efficiency energy-saving submersible mixerStructure Introduction and Performance Characteristics:

1. Compact structure, small volume, and light weight. Easy operation and maintenance, convenient and fast installation, and long service life.

2. The blades have self-cleaning function, which can prevent debris from entangling and blocking.

3. When used in conjunction with an aeration system, energy consumption can be significantly reduced, oxygen filling can be significantly increased, and sedimentation can be effectively prevented.

4. The motor winding is insulated to Class F with a protection level of IP68. It uses imported bearings with one-time lubrication and maintenance free function, which have oil chamber leakage detection and motor winding overheating protection functions, making the operation of the motor safer and more reliable.

5. The friction material of the mechanical seal is corrosion-resistant tungsten carbide, and all fasteners are made of stainless steel material.
