Features ：
1) Fewer transmission links, high mechanical efficiency, compact structure, and smooth operation.
2) Small footprint, high throughput, and low energy consumption;
3) Low installation, operation, and maintenance costs.
4) Achieves the required mixing intensity within the specified mixing time, ensuring fast, even, and thorough mixing, with minimal head loss. It is adaptable to changes in water volume, making it suitable for waterworks of varying capacities.
Construction and Operating Process ：
The JBJ type propeller mixer consists of a motor, reducer, frame, stirrer shaft, propeller blades, couplings, underwater brackets, etc. It can be classified according to the sealing method: Type A: with mechanical sealing, Type B: without sealing, Type C: other sealing methods, suitable for different sealing requirements.
The drive unit employs a standard motor or an explosion-proof motor, along with a harmonic drive reducer. The main shaft of the drive unit is connected to the agitator shaft via a coupling, which is supported by bearings, offering sufficient strength and high stability.
The mixer impeller features a 45-degree bent-blade design, which generates axial, radial, and circumferential分流, enabling rapid and thorough mixing of materials with water, meeting process requirements.

1. During storage and transportation, the long shaft should be as upright as possible; if it must be laid horizontally, prevent it from being crushed or deformed.
2. Be cautious to avoid collisions during lifting.
3. Installation Method:
1) Prior to installation, verify that the fundamental dimensions of the equipment to be installed meet the installation requirements. 2) After securely fastening the reducer bracket to the connecting base plate, place it horizontally on the corresponding position of the pre-buried construction components.
Check and adjust the connection plane between the alignment bracket and the reducer to ensure it is level.
3) Connect the mixer shaft to the reducer base.
4) For propeller mixers with underwater pedestals: After securely fastening the underwater pedestal to the connecting base, place the assembly horizontally on the corresponding position of the pre-buried construction on the pool bottom. Check and adjust the pedestal plane for levelness, ensuring the center position is aligned with the centroid of the reducer pedestal, and make necessary adjustments to achieve a level state.
5) For propeller mixers with underwater supports: Connect the mixer shaft to the underwater support, manually rotate the inner half coupling of the reducer support, at this time, the shaft should rotate smoothly, and the underwater support should not show any significant displacement.
6) For mixers with underwater supports: First, spot-weld the underwater support to the bottom plate and the foundation embedded plate. Then, spot-weld the reducer support to the bottom plate and the foundation embedded plate.
7) Rotate the half coupling of the hand-operated decelerator bracket. The shaft should rotate smoothly. If there is any resistance, resecure it until it operates properly. Weld the bottom plate of the decelerator bracket to the foundation embed plate. For mixers with underwater brackets, proceed to weld the bottom plate of the underwater bracket to the foundation embed plate.
8) Install paddle blades and drive components (reducer, motor).
9) Tightly secure the bolts and nuts on the half coupling
Dialing Method:
Before tuning, oil should be added according to the reducer's specifications.
2) Inspect the insulation level of the drive motor; the insulation resistance to ground must not be less than 5MΩ.
3) Connect the motor to the control system according to the specified motor connection method. Refer to the electrical control schematic and user manual for the control system wiring.
4) Prior to the official operation of the mixer after installation, a trial run is mandatory. During the trial run, the mixer should operate smoothly in no-load conditions before gradually increasing the load. The equipment should run without any abnormal vibration during the trial run.
