Product Introduction:
The submersible mixer is successfully developed by introducing German submersible motor sealing technology. After years of practical exploration and innovation in form, structure and test methods, the overall performance of Lanjiang submersible mixer has reached the level of similar foreign products. Casting type submersible mixer./- can be divided into two series: mixing and low-speed push flow. Mixing series mixers are suitable for mixing liquids containing suspended solids in sewage treatment plants and industrial processes. Low-speed push flow series mixers are suitable for aeration tanks in industrial and urban sewage treatment plants. The strong water flow generated by low tangential flow can be used for circulation, nitrification, and dehydration. Nitrogen and phosphorus removal stages create water flows, etc.

Key points to note:
The submersible mixer must be completely submerged in the water to work and cannot be used in an environment with flammable, explosive or highly corrosive liquids. The working steel expansion bolts must be fixed as required. After installation, the cables must be tightened and fixed
When selecting a submersible flow booster, the blade diameter exceeds the recommended use of a gearbox reducer
Performance characteristics:
Compact structure, simple operation and maintenance, convenient installation and maintenance, and long service life
The impeller has the best hydraulic design structure and high working efficiency. The swept-back blades have a self-cleaning function to prevent entanglement and clogging of debris
and exposure The mixed use of gas system can significantly reduce energy consumption and significantly increase the amount of oxygen, effectively preventing precipitation
The motor winding insulation level and protection level are selected from high-quality bearings and motor anti-condensation devices to make the motor work safer

Precautions for selection:
The selection of submersible mixer is a relatively complex task. Whether the selection is correct or not is straightforward. The principle that affects the normal use of the equipment is to allow the mixer to exert its full mixing function in a suitable volume, which can generally be determined by the flow rate. According to the different process requirements of the sewage treatment plant, the optimal flow rate of the mixer should be guaranteed to be between .~./. If the flow rate is lower than ./, the push flow mixing effect will not be achieved. A flow rate exceeding ./ will affect the process effect and cause waste. Therefore, before selecting the model, first determine the place where the submersible mixer is used, such as sewage pool, sludge pool, and biochemical pool, followed by the parameters of the medium such as: suspended solids content, viscosity, temperature, value, and the shape of the pool, water depth, etc. The supporting power required by the mixer is determined according to the volume, density of the mixing liquid and mixing depth. One or more mixers are used according to the specific situation.
Mixing type
Determine the sludge correction coefficient of the medium to be stirred according to the chart or table.
Determine the tank type correction coefficient of the mixing tank according to the chart or table.
According to the power consumption per cubic meter of clean water multiplied by the sludge correction coefficient and then multiplied by the pool correction coefficient, the actual value of the power consumption per cubic meter of the stirring medium to be mixed is obtained, and then multiplied by The volume of the medium to be stirred gives the power required for the entire tank of the stirred medium to be mixed.
Low speed push flow type
Determine the pool type correction coefficient of the mixing pool according to the chart or table.
Determine the sludge correction coefficient of the medium to be stirred according to the chart or table.
Determine the power consumption per unit flow rate through the graph based on the initial flow rate of the stirring medium.
Calculate the flow rate of the mixer by multiplying the initial flow rate of the stirring medium by the cross-sectional area formed when the impeller rotates.
Multiply the flow rate of the mixer by the power consumption per unit flow rate and then multiply it by the sludge correction coefficient and the pool type correction coefficient to get the power required for the entire pool medium
