QJB submersible mixer flow velocity diagram: The above flow velocity field is under the condition of V=0.1m/s in clear water with a water flow velocity of the gap. ■ QJB submersible mixer selection reference: The selection of a submersible mixer is a complex task, and the correctness of the selection plan directly affects the normal operation of the equipment. As a criterion for selection, it is necessary to ensure that the mixer can fully perform its mixing function within the appropriate capacity of the platform. This standard can generally be determined by the flow rate. According to the different process requirements of the sewage treatment plant, the optimal flow rate for the selection of the mixer should be between 0.15-0.3m/s. If the flow rate is lower than 0.15m/s, it will not achieve the effect of push flow mixing. If the flow rate exceeds 0.3m/s, it will affect the process results and form waste. Operation mode of QJB submersible mixer: The positioning of the submersible mixer equipment has a significant impact on its mixing function. In order to achieve twice the result with half the effort, we advocate that users follow the requirements of professional planners, fully consider the shape of the pool, the direction of water inflow and outflow, and the vortex caused by the water flow reflected by the mixer to the structure, and minimize the occurrence of short circuit circulation and dead corners, avoiding the impact with the pool wall and reducing the flow rate. Referring to the operation diagram below can help you choose a reasonable mixer and equipment mode.

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.
1. The maximum medium temperature shall not exceed 40 ℃;
2. The pH value of the medium is between 5 and 9;
3. The liquid density shall not exceed 1150kg/m3;
4. Long term diving operation, with a diving depth generally not exceeding 20m.
Warning!
It is necessary to thoroughly submerge the submersible mixer for operation, and it should not be operated in environments that are flammable, explosive, or highly corrosive!
2. The impeller has the best hydraulic planning structure, high operating efficiency, and the swept back blades have self-cleaning function to prevent debris from surrounding and blocking.
3. Mixing with the aeration system can significantly reduce energy consumption, increase oxygen filling capacity, and effectively avoid accumulation.
4. The insulation level of the motor winding is F level, and the protection level is IP68. Imported bearings and unique patented motor anti condensation equipment are selected to make the operation of the motor safer and more reliable.
5. Two mechanical seals, made of tungsten carbide tungsten carbide material.
6. According to the process requirements, direct coupled submersible mixing can be equipped with a guide cover.
7. The stainless steel and carbon steel precision cast welded blades of the submersible mixer have been optimized to have swept blades with high efficiency and self-cleaning function.
8. There are leakage sensors and stator winding over temperature maintenance alarm devices inside.
The low-speed thrust series products use cycloidal pinwheel reducers, which have low equipment power, low speed, large impeller diameter, and wide service area. The impeller is made of polyurethane material and aluminum alloy, with high strength and strong corrosion resistance. In addition to its mixing function, it also has the functions of pushing and creating water flow.
The motor winding of the submersible mixer is F-class insulated and has a protection level of IP68. Cooperative application in the aeration system of sewage treatment plants can greatly reduce energy consumption and significantly increase oxygen filling, effectively avoiding accumulation. According to the process requirements, direct coupled submersible mixing can be equipped with a guide cover.
So before selecting, the first thing to determine is where the submersible mixer is used, such as sewage tanks, sludge tanks, or biochemical tanks; Next is the reference of the medium, such as suspended solids content, temperature, pH value, etc. The shape, depth, and equipment method of the water tank will also affect the selection. Energy saving factors should also be considered, as this will affect the user's future operating costs. Please refer to the flow field diagram of the constant water mixer below. In order to achieve the best mixing performance in different environments, we provide users with various types of submersible mixers, which can be selected together.
The QJB submersible mixer is primarily used for mixing, blending, and circulating in municipal and industrial wastewater treatment processes, and can also be used for maintaining landscape water environments. Through the rotation of the impeller, it creates water flow, improves water quality, adds oxygen content to the water, and effectively blocks the accumulation of suspended solids. The process and industrial flow require a place where solid liquid two-phase or solid liquid gas three-phase media are uniformly mixed and reacted.
