Selection of submersible mixer

Structure of submersible mixer:

The submersible mixer mainly consists of a submersible mixer host, installation system, and electrical control equipment.

Submersible mixers are divided into hybrid submersible mixers and low-speed push flow mixers according to their functions. Hybrid submersible mixers are divided into direct coupled stamping submersible mixers and non direct coupled submersible mixers according to their structural characteristics. The low-speed push flow submersible mixer belongs to the non direct coupled submersible mixer.

Hybrid submersible mixers are divided into casting mixers and stamping mixers according to their blade forming methods. The blades (impellers) of the casting mixer are formed by casting, and the material of the body shell is generally cast iron. The blades of the stamping mixer are formed by stamping, and the material of the body shell is generally stainless steel.

Hybrid submersible mixers are generally equipped with flow deflectors to increase axial flow and reduce radial flow, reduce impeller vibration, and increase operational stability. However, low-speed push flow submersible mixers are not equipped with flow deflectors.

The specialized installation system of QJB submersible mixer can quickly install and disassemble the submersible mixer without the need to discharge sewage from the pool. When the pool depth H is less than 4 meters, it is recommended to use installation system I. The diving depth of the submersible mixer can be adjusted vertically as needed, and the maximum angle that can rotate around the guide rod in the horizontal plane is ± 60 °. The lifting system base, support frame, and lower bracket are all fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes. When the pool depth H is greater than 4 meters, it is recommended to use installation system II, which requires a concrete foundation (or steel structure base) to be built at the bottom of the pool. The lifting system base, steel rope fixing frame, and guide base are all fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes. The installation system II uses guide steel ropes instead of guide rods, which has the characteristics of convenient transportation and simple on-site installation. This system fundamentally avoids the situation of guide rod bending and deformation caused by transportation, which affects normal use, and effectively improves the phenomenon of inability to lift due to installation errors of guide rods when the pool is too deep. Under the installation conditions with a cantilevered pool roof (as shown in the picture), it appears more convenient and reliable to operate. When the customer places an order, please provide the pool depth H and pool type diagram so that the factory can determine the size of the guide rod or guide wire during processing. The material of the installation system is made of stainless steel (or carbon steel). In addition to guide rods or guide wires, and lifting bases, multiple mixers can share a set of lifting devices in the installation system (except for special user requirements).

Performance characteristics of QJB submersible mixer

The QJB submersible mixer is mainly composed of submersible motor, sealing mechanism, impeller, guide cover, hand hoist, electrical control and other parts. The stirring impeller rotates and stirs the liquid under the drive of the motor, generating a rotating jet and using the shear stress along the jet surface to mix. The liquid outside the flow field is stirred by friction, forming a volumetric flow while extremely mixing. The controlled fluid transport is achieved by applying a large volume flow mode.

Performance characteristics of QJB submersible mixer

1. The submersible mixer has a compact structure, simple operation and maintenance, easy installation and maintenance, and a long service life.

2. The impeller has the best hydraulic design structure, high working efficiency, and the swept back blades have self-cleaning function to prevent debris entanglement and blockage.

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 level, and the protection level is IP68. Imported bearings and a unique patented motor anti condensation device 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, the direct coupled submersible mixer can be equipped with a guide cover.

7. The stainless steel and carbon steel precision cast welded blades of the submersible mixer are optimized to have swept blades with high efficiency and self-cleaning function.

8. There are leakage sensors and stator winding over temperature protection alarm devices inside.
