: >Product Introduction:
: >The submersible mixer is successfully developed by introducing German submersible motor sealing technology. After years of practice and exploration, the overall performance of the submersible mixer has reached the level of similar foreign products due to its innovations in form, structure and testing methods.
: >B-type submersible mixers 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 of industrial and urban sewage treatment plants, which produce low The strong tangential flow of water can be used to create water flow in circulation and
:> nitrification, denitrification and phosphorus removal stages.
: >Scope of application:
: >The mixer should be able to operate normally and continuously under the following conditions:
: >The maximum medium temperature does not exceed
:>The value of the medium is between ~< br/> : > The liquid density does not exceed
: > For long-term diving operations, the diving depth generally does not exceed.
: >Important matters to note:
: >The submersible mixer must be completely submerged in the water to work and cannot work in an environment with flammable, explosive or highly corrosive liquids
: >Steel expansion bolts must be pressed It is required to be fixed. After installation, the cable must be tightened and fixed.
:>When selecting a submersible flow booster, if the blade diameter exceeds the limit, it is recommended to use 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 and can Prevent debris from entanglement and clogging
:> Mixed use with the aeration system can significantly reduce energy consumption, significantly increase the oxygenation amount, and effectively prevent precipitation
:> The motor winding insulation level is 100%, and the protection level is , using high-quality bearings and motor anti-condensation devices to make the motor work safer

: >Selection Precautions:
: >The selection of a submersible mixer is a relatively complex task. The correct selection directly affects the normal use of the equipment. As a reference for selection Principle
: >It 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 . >. The flow rate will affect the process effect and cause waste. Therefore, before selecting the model, first determine the place where the submersible mixer will be used, such as: sewage pool,
:> sludge pool, biochemical pool, followed by the parameters of the medium, such as: suspended solids content, viscosity, temperature, value and pool. shape, water depth, etc.
: >The supporting power required for the mixer is determined based on the volume, density of the mixing liquid and mixing depth. One or
: >multiple mixers are used depending on the specific situation.
: >Flow velocity diagram of submersible mixer:
