Submersible installation of multi surface mixer

The impeller structure of a multi surface mixer mainly consists of a guide section and a rib mixing section. The diversion part plays a role in guiding the flow of water to achieve flexible transition and form a three-dimensional circulating flow state. It is an essential component of the hyperbolic impeller, and the stirring ribs are the power source of water movement. At the same time, they cooperate with the reflection effect at the bottom of the pool to generate turbulent flow and enhance the mixing effect. The mixer should be specially designed and manufactured for continuous mixing and reaction processes in sewage treatment, and can generate a uniform fluid motion pattern from top to bottom in the tank.

The seller shall determine the rated shaft power, motor power, and speed of the mixer based on the provided process conditions, pool shape, size, and experience.

The type of agitator impeller should meet the process requirements, the motor power should meet the performance requirements of the agitator, and the impeller diameter should be: φ=2000mm。 The seller shall provide explanations in the bidding documents regarding the form of the mixer, blade diameter, power, etc.

The mixer shaft and blades have sufficient strength, stiffness, and vibration resistance to ensure smooth operation under various design conditions without abnormal vibration.

The deceleration device of the mixer can transmit the required power for operation under various design conditions and withstand the load transmitted by the mixing shaft.

The support of the mixer shaft can bear the weight of the mixing shaft and impeller, and can withstand all torques, bending moments, and axial loads.

The material of the mixer should meet the water quality requirements.

The material and performance of the electric motor should comply with the relevant technical standards issued by GB755, ASTM, and IEC.

The motor should be suitable for operation with a 380VAC 3PH 50Hz power supply, with a protection level of IP55 and an insulation level of F, and should be installed vertically outdoors.

sellerEquipment providedShould be able to ensure meteorological conditions in the regiondaily24Long term stable operation in a continuous or intermittent manner, and the ability to start and operate normally even after long-term shutdown.

The mixer itself should have speed regulation function (without a frequency converter).

Introduction to the Structure of Multi surface Blender

Nanjing Du'an Water Treatment GSJ/QSJThe hyperbolic mixer consists of a reduction motor, shock absorber seat, mixing shaft, hyperbolic impeller, electric control box, and bridge (used for) Household can bring their own) and other components

IIITransportation and Storage

1During transportation, the mixing shaft and impeller must not be subjected to pressure or collision, and must be loaded and unloaded using lifting equipment. The surface of the impeller should be protected from scratches.2Long term storage should avoid high temperature and high humidity environments. The mixing shaft should be suspended vertically, and the impeller should be placed on a flat surface to prevent deformation.

4、 Multi surface mixer submersibleInstallation and bridge installation

1The bridge frame should be calibrated horizontally, and the half bridge frame columns should be calibrated vertically. The anchor bolts and connecting parts should be sturdy and reliable.

2Place the shock absorber seat flat on the designated position of the bridge frame, align it horizontally, and connect it to the bridge frame for fixation.

3The deceleration motor is installed on the shock absorber seat and connected and fixed.

4Connect and tighten the impeller and mixing shaft flange with bolts.

5Place the impeller and mixing shaft into the pool, connect and tighten the mixing shaft to the output shaft of the reducer.

6After the installation of the mixer, the mixing shaft must be perpendicular to the horizontal plane. Vertical deviation less than1/1000And not exceeding5mm.

7After installation, remove the motor tail cover and manually rotate the fan blades to check if the mixer rotates flexibly and normally. The swing deviation of the mixing shaft should be less than3/1000

8After turning on the power, observe the rotation direction of the mixing shaft by jogging. The correct rotation direction is counterclockwise when viewed from top to bottom. If the opposite is true, then switch arbitrarily2Root power supply wiring location.

9Electrical equipment installation must be operated in accordance with relevant national regulations and safety regulations.

5、 Equipment'srun

After the installation of the equipment is completed, a trial run must be conducted. Before trial operation, approximately the capacity of the pool must be injected into the pool70%Do not operate the equipment without water to prevent the mixing shaft from bending due to uneven force. Pay attention to checking after trial operation:

1Check for any abnormal noise or temperature rise in the deceleration motor.

2Is the motor current within the rated range (it is normal for overcurrent to occur within a short period of time during startup).

3、The swinging situation of the mixing shaft. In any of the above situations where abnormal phenomena occur, the cause must be identified and corrected. Note: The rotation direction of the mixer should be adjusted to correspond to the rotation direction of the blade reinforcement ribs.

Multi surface mixerMaintenance

1The new machine starts running200～300It is necessary to replace the lubricating oil of the gearbox and clean the internal oil stains when working. In the future, it can be replaced once every six months to one year; For detailed information on the use of the deceleration motor, please refer to the manufacturer's user and maintenance manual.

2Regularly check whether the locking nut and connecting bolts of the mixing shaft are loose.

3Regularly check the swing of the mixing shaft.

4Regularly check for abnormal sounds and temperature rise in rotating components.

5Regularly check for any abnormal changes in current. The above inspections should be recorded properly. If any abnormal situations occur, please contact our company.
