Duwan Environmental QJB Submersible AgitatorStructural Design:
Duwan Environmental Duwan Environmental DivingThe mixer is an overall design with a sealed connection and submersible type. All components of the mixer, including the motor, can operate continuously underwater. All exposed nuts, bolts, and washers are made of stainless steel. The oil chamber cover is made of corrosion-resistant synthetic material.
(1Terminal Box
The junction box is made of stainless steel and is fully enclosed, providing complete isolation from surrounding liquids and motor parts; the cable is a specially processed sealed waterproof cable.
(2Mechanical Seal
The shaft seal features a two-segment independent mechanical seal structure, with the sealing friction material made of corrosion-resistant sintered tungsten carbide./Silicon carbide, running sealed within an oil cavity, with an ample oil supply and space, can lubricate the overlapping sealing surfaces at a stable flow rate. The external mechanical seal is made of corrosion-resistant sintered tungsten carbide./Silicon carbide, to prevent the slurry from entering the oil cavity. Internal mechanical seal made of silicon carbide./Silicon carbide, prevents oil from the cavity entering the motor. The internal and external mechanical seals operate independently.
Static Sealing SolutionOO-Ring Sealing, material: Fluororubber.
(3Bearings
The motor shaft is equipped with a deep groove ball bearing and a double-row angular contact ball bearing; all bearings are maintenance-free imported bearings.NSKOr (SKF),Design Life Exceeds150000Hourly
(4Motor
The motor of the submerged mixer is a squirrel-cage induction motor, with the rated power value exceeding the expected load by at least.10%The unit is connected to the impeller through a deceleration device, with its winding having an insulation grade ofFGrade, working temperature up to155OCThere is no Chinese content provided for translation.Please provide the Chinese content you would like translated.Under heavy mixing loads, there is no risk of overload, and the motor can start up no less than every hour.15However, the intervals should be uniform. The motor is designed with a shell filled with inert gas, internally filled with inert gas.,To prevent condensation inside the motor and the intrusion of external dirt. The motor stator is securely embedded in the housing using the hot sleeve method, ensuring reliability. Under normal conditions, the motor's temperature rise does not exceed80OC,
(5Protective Device
Leak detectors are installed in the stator cavity and oil chamber to detect both dynamic and static seal leaks, and to promptly shut off the power supply. The stator cavity leak sensor is connected to the motor terminal box via wiring.
(6Cooling
Cooling of the motor is achieved through liquid heat conduction around the housing. The motor stator is embedded in the housing with a heat sleeve to enhance its thermal conductivity efficiency.
Duwan Environmental Submersible MixersService Life
Duwan Environmental DivingThe mixer operates continuously, intermittently, and after a long period of shutdown under specified conditions, maintaining a smooth operation throughout the process. The average running time prior to the first failure is no less than15000Hour.
