Totally Enclosed low Voltage Submersible Motor for Industrial Wastewater Treatment YQGN520 Series Safety High Efficiency
This series of motors have the advantages of high efficiency, energy saving, low noise, low vibration, low temperature rise and reliable operation. The power level of the motor is in accordance with IEC standard, the protection level of the motor shell is IP68, the rated voltage of the motor is manufactured according to 380V, 660V, 6000V, 10,000V, the rated frequency is 50Hz, the working system is S1, the insulation level is F, and it adopts the vacuum pressure impregnation process of VPI, which is with reliable waterproof performance.
YQGN520 series low voltage submersible motors are dry type fully enclosed submersible three-phase asynchronous motors. Adopting multi-channel dynamic and static seals and special insulation technology, it can reach F class insulation and IP68 (IEC) protection level. It is assembled with the pump section to form a submersible electric pump, which can be operated underwater for a long time.The reliability of submersible motors depends mainly on the advanced design and manufacturing process of submersible motors.
Technical Advantages：
A.As the submersible motor is dry structure, the high power submersible motor often adopts three mechanical seals and advanced cable joint sealing technology.
B. The first thrust bearing lubrication and cooling system, for high-power submersible motor operation thrust bearing temperature rise does not exceed 40K.
C.Molding coil production and winding connection design with special thickened insulation insulation, with reliable waterproof performance.
D. Setting a variety of automatic protection devices, such as internal leakage of the junction box, water inside the motor, overheating of the windings, water in the oil chamber, overheating of the thrust bearings, as well as automatic monitoring of the insulation resistance of the motor and so on.
