1Structural diagram of stainless steel permanent magnet energy-saving submersible mixer for anoxic tankProduct Usage

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.

1. Performance characteristics

Ultra durable

The efficiency of permanent magnet motors, the absence of resistance losses in the rotor winding, and the minimal or almost non-existent reactive current in the stator winding result in low temperature rise during long-term operation. Compared with ordinary motors, this significantly extends the working time and service life of the motor.

2. Super energy-saving

All models meet the * and level 2 energy efficiency indicators, and the permanent magnet electric power factor used is all greater than 0.9. The permanent magnet high-efficiency submersible mixer saves 15% to 30% of energy consumption compared to ordinary submersible mixers, and a single ultra energy-saving mixer can save more than 30000 kWh of electricity per year.

Super convenient

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.
