Duwan Environmental QJB620/480-7.5There are various installation methods for submersible mixers, primarily depending on the installation system and dimensions. Common installation methods for submersible mixers are as follows:
Duwan Environmental ProtectionSubmersible mixerThe installation requirements are as follows:
Ensure the mixer is easily removable during maintenance.
② The mixer's lifting chain should be securely fastened to a specific location within the wellbore for easy future use.
Each mixer is installed within a fixed structure, with the mixer being capable of being lowered into place within the structure through a guide device.
④ Assembly marks should be made between each component, and locating pins should be provided where necessary to ensure accurate reassembly and alignment on-site.
The mixer accessories and their cables should be capable of continuous operation submerged in 20 meters of water without damage, and should possess enhanced sealing reliability.
Installation MethodThe submersible mixer is primarily composed of the guide rod, upper turntable, support paddle, and lower turntable. It is suspended below the guide rod, which is fixed to the upper support frame via the upper turntable. The mixer can be installed at a certain angle between the vertical and horizontal planes by adjusting the position of the connecting bolts on the lower turntable. Additionally, the mixer can rotate 360° around the axis of the upper turntable by adjusting the position of the connecting bolts between the upper turntable and the guide rod, accommodating different mixing directions, eliminating dead zones in the pool, and ensuring optimal water flow.
Installation MethodThe unit is primarily composed of hand winches, lifting frames, straight lifting shackles, brackets, guide rods, intermediate support blades (not required for pool depths ≤ 6 meters), limit frames, and bases. The guide rod is positioned on the bracket, intermediate support frame, and base concentric axes by means of a hinge shaft welded to the body, and it can rotate ±60° within the horizontal plane to accommodate different directions of stirring or flow, eliminating dead zones in the pool and ensuring better water flow. The submersible mixer moves up and down the guide rod via guide wheels. The lifting frame can be mounted on the bracket and can rotate 360° around its positioning axis for easy installation and maintenance. To enhance the reliability of the submersible mixer during operation and to reduce vibration, the limit frame is typically welded directly to the guide rod and equipped with shock-absorbing pads between the mixer and the limit frame. The limit frame can be welded to the guide rod either before shipment or during on-site installation. Unless the customer has specific requirements, the welding is usually done before shipment.
Submersible AgitatorThe diving depth can be adjusted vertically as required. The connection between the suspension bracket, support frame, and lower support bracket to the pool is fixed with expansion bolts, no pre-drilled holes are needed. When placing an order, please provide the pool depth.H, for us to determine the rod size and the number of support frames during processing. The material used for the installation system is made of stainless steel (or carbon steel). Multiple mixers can share a single hoisting device, excluding the hoist base.

Duwan Environmental QJB620/480-7.5 Submersible Agitator Maintenance Instructions.
Regularly replace lubricating oil, typically every six months.
Be extra cautious of the equipment's sealing when disassembling the machine.
3. Regularly replace bearings.
If the fuel tank becomes blocked, it should be addressed promptly.
Submersible AgitatorIn case of a water seal failure, it is essential to replace it promptly. Specific steps can be referred to as follows.
Remove the stirrer from the engine.
Remove the nut at the front end of the stirrer shaft, detach the cover, and push out the impeller and water seal.
3. Inspect the water seal; if it's made of rubberwood and the wear is not severe, you can place sandpaper on glass or dry wood to flatten or flip the water seal for use. For pusher rubber seals, if there is damage, expansion, deformation, insufficient spring pressure, or breakage, they should all be replaced with new parts.
Step 4: Install water seals and lock rings, etc.
Reinstall the belt pulley and mixer cover, and tighten the fixing nuts.
6. Mixer Assembly Inspection: Upon reassembling the mixer, rotate the belt wheel by hand, ensuring there are no obstructions on the mixer shaft and no collision sounds between the impeller and the mixer housing.
Step 7: Reinstall the mixer onto the engine and secure the hoses, etc.
8. Inspection of Submersible Agitator Performance: After reassembly, fill with cooling water, start the engine, and after 5 minutes of operation, the submersible agitator should exhibit no impact sounds or leakage, indicating good performance.
