submersible mixer
Brief description:
The type selection of casting submersible mixer is a complex work. The correct type selection directly affects the normal use of the equipment. As the principle of type selection, the mixer should give full play to the mixing function in a suitable volume. Generally, the flow rate can be used to determine

Product features of casting submersible mixer
1. The submersible mixer has compact structure, simple operation and maintenance, convenient installation and maintenance, and long service life;
2. The impeller of submersible mixer has hydraulic design structure, high working efficiency, swept back blade has self-cleaning function, which can prevent foreign matters from winding and blocking;
3. The mixing use of submersible mixer and aeration system can greatly reduce the energy consumption, increase the oxygen content and effectively prevent precipitation;
4. The insulation grade of motor winding is f, and the protection grade is IP68. High quality bearing and anti condensation device are selected to make the motor work safer;
5. Two mechanical seals;
Scope of application and precautions
The mixer shall be able to operate normally and continuously under the following conditions:
1. Zui high medium temperature does not exceed 40 ° C;
2. The pH value of the medium is between 5 and 9;
3. The liquid density shall not exceed 1150Kg / m3;
4. For long-term diving operation, the diving depth is generally less than 20m.
Key points for attention:
The submersible mixer must fully submerge into the water; it can not work in the environment of flammable and explosive or corrosive liquid; the steel expansion bolt must be fixed according to the requirements, and the cable must be tightened and fixed after the installation
When selecting submersible thruster, the blade diameter is more than 2m, so gearbox reducer is recommended
Product description
QJB2.2/8-320/3-740S
QJB: phonetic abbreviation of submersible mixer
320 - nominal diameter of impeller
740 --- impeller speed (RPM)
2.2 ----- motor power (kw)
Thrust range: ≤ 320n

Submersible mixer has a variety of model parameters, the following is the common range of Zui model
Power range: 0.85-15kw
Impeller diameter range: 260-620mm
Impeller speed range: 480-1400r / min
Precautions for model selection:
The selection of submersible mixer is a complex work, and the correct selection directly affects the normal use of the equipment. As the principle of selection, the mixer should give full play to the mixing function in a suitable volume, which can be determined by the flow rate. According to the different process requirements of the sewage treatment plant, the best flow rate of the mixer should be between 0.15 ~ 0.3m/s. If the flow rate is lower than 0.15m/s, the plug flow mixing effect will not be achieved. If the flow rate is higher than 0.3m/s, the process effect will be affected and waste will be caused. Therefore, before the selection of submersible mixer, the first place to use is determined, such as sewage tank, sludge tank, biochemical tank; the second is the medium parameters, such as suspended solids content, viscosity, temperature, pH value; and the shape and depth of the pool.
The matching power required by the mixer is determined according to the volume size, the density of the mixing liquid and the mixing depth. One or more mixers are used according to the specific situation.
Performance parameter table:
The mixer is under the condition of rated voltage 380V, frequency 50Hz, winding insulation grade F, protection grade IP68 and working mode I.
