Sell Asynchronous Motor Explosion-Isolating Three-Phase

Explosion-isolating three-phase asynchronous motor for YBJY80M2-4 fuel and oil machines (Abbr. To Motor) is suitable in dangerous and explosive places resulting from flammable gas or steam with Grade 11A, 11B, temperature grade T1-T4 and air. Anti-explosive property of the motor conforms to the specification of GB3836, 1-2000 Explosive Gas Environmental & Electric Equipment Part 1: General Requirements, GB3836.2-2000 Explosive Gas Environmental & Electric Equipment Part 11: Explosion-isolating Type d. Anti-explosive marking is Exd11AT4, Exd11BT4. Motor should be able to work reliably in case of the following conditions: 1) Height above the sea level is lower than 1,000m 2) Environmental Temperature is changing seasonally, but not less than 15° and up to 40°C 3) Monthly average and relative max-temperature: 95% in the warmest month, and the average min-temperature of the month: not less than 25°C 4) Protection grade of motor: IP 54 5) Rated pressure of motor: 380V 6) Rated current of motor: 2A 7) Rated power of motor: 750W 8) Rated turns of motor: 1,390r/min 9) Working methods of motor: (S1) rated successively 10) Insulation grade of motor: class F 11) Temperature limits of stator wounded (Resistance Method): Installment and maintenance: 1) Anti-explosive grade and temperature extent should conform to the grades and extent of explosive mixture in the corresponding explosive and dangerous places 2) To measure insulating resistance, it is not allowed to be less than 0.4m in working temperature 　 and 20m in room temperature 3) Turn the shaft of the motor slightly, flexibly without noise 4) Outer bolts shall be grounded reliably 5) Pay attention to protect the explosion-isolating surface in case of dismantling motor, and coat 　 anti-rust oil 204-1 on the surface as installed 6) Check motor at least on annual basis, and replace lubricant often (MoS2) 7) When storing motor, keep it dry and ventilated
