Duwan Environmental QJB Submersible Mixer Technical Requirements

Submersible mixers consist of impellers, submersible motors, installation lifting rods, angle turning devices, etc.

The submersible agitator rotates smoothly without jamming, stalling, or vibration.

The潜水 mixer undergoes a sealed pressure test at a pressure of 3 Kg/m², with no leakage observed for a duration of 5 minutes.

Submersible mixers are equipped with double mechanical seals, with a lifespan of the mechanical seals not less than 25,000 hours.

Submersible mixers operate continuously underwater, ensuring they can still run normally upon startup after intermittent operation or long-term shutdown.

The surface of the submersible mixer is coated with anti-corrosion paint, maintaining a glossy finish without any stains, dents, or cracks.

The oil chamber of the submersible mixer has ample space to accommodate expansion caused by temperature differences, with discharge pipes and inspection openings provided.

Seal Leak Protection Device

Submersible mixers are equipped with underwater cables for control and power, each cable having a separate import and being reliably sealed. Cables connected to the junction box can be resealed with rubber gaskets.

The submersible mixer's stator winding is equipped with a thermal protection switch.

The installation rod of the submerged mixer ensures the device can rotate freely, lift, lower, and adjust to various angles, facilitating the lifting and installation process.

The blender does not need to empty the pond.

Service Life: The潜水搅拌机is designed for initial use under specified conditions.Average running time before failure is not less than 10,000 hours, with a lifespan of not less than 15 years for the entire machine.

Impeller: Made of 316L stainless steel, precision-engineered, and tested for dynamic balance, featuring a non-clogging, hydraulically balanced pull-back design for efficient power transmission from the motor for mixing and propelling the pool's bottom sludge. To prevent clogging and ensure the impeller does not loosen on the shaft during operation, an internal locking device can be used.

Motor: Gearbox design is not accepted; motor winding insulation is H class, protection rating is IP68; the motor shaft and rotor are tested for dynamic balance.Generally normalOperating Temperature 180°C. Normally, the motor temperature does not exceed 130°C. The motor can start up 30 times per hour.

Bearings: The motor and impeller of the agitator are directly coupled. The shaft is made of wear-resistant stainless steel, capable of withstanding all axial and radial loads. The shaft of the impeller and the motor should be the same, and the impeller shaft must be an extension of the motor shaft.

The coupling will not be accepted. The impeller shaft should be completely isolated from the mixing medium. The service life of the agitator bearing is greater than 100,000 hours.

Monitoring System: A thermosensitive switch should be installed in the stator winding, with the set temperature for the switch to open at At 125°C, the closed temperature is 95°C, and it can be connected to the motor overload protection.DivingLeak sensors are installed inside the blender to monitor for leaks.
