QJB type submersible mixer

The QJB submersible mixer can be divided into two series: mixed mixing and low-speed push flow.
The mixing series mixer is suitable for mixing liquids containing suspended solids in sewage treatment plants and industrial processes;
The low-speed push flow series mixer is suitable for aeration tanks in industrial and urban sewage treatment plants. It produces strong water flow with low tangential flow, which can be used for circulation, nitrification, denitrification, and phosphorus removal stages to create water flow.
FQJB type floating submersible mixer
The FQJB floating submersible mixer is a modified version of the submersible mixer, with the addition of a stainless steel float. The specific selection is based on the QJB submersible mixer.
Scope of application:
The mixer should be able to operate continuously and normally under the following conditions:
1. The temperature of the medium shall not exceed 40 ° C;
2. The pH value of the medium is between 5 and 9;
3. Liquid density not exceeding 1150kg/m3;
4. Long term diving operation, with a diving depth generally not exceeding 20m.
Key precautions:
The submersible mixer must work completely submerged in water; Cannot work in environments with flammable, explosive, or highly corrosive liquids; The steel expansion bolt must be fixed as required, and after installation, the cable must be tightened and fixed securely.
All impellers of the submersible thruster are made of polyurethane material, and the gearbox reducer is a helical gearbox.
Performance characteristics:
1. Compact structure, easy operation and maintenance, convenient installation and maintenance, long service life;
2. The impeller has a reasonable hydraulic design structure, high working efficiency, and the swept back blades have self-cleaning function, which can prevent debris from entangling and blocking;
3. Mixing with the aeration system can significantly reduce energy consumption, increase oxygen filling capacity, and effectively prevent sedimentation;
4. The insulation level of the motor winding is F, and the protection level is IP68. NSK/SKF bearings are used, and the motor can be equipped with anti condensation devices. The motor uses an over temperature protection device to make its operation more reliable;
5. Two mechanical seals; The mechanical seal is sealed with tungsten carbide material, and the rubber material is fluororubber;
