YBJ40-4 Mining Hoist Special Explosion-proof Motor

Model Number: YBJ40-4 Brand Name: Yu anti-explosion Key Specifications/Special Features: YBJ winch use explosion-proof motor is introduced:YBJ flame-proof explosion-proof motor function implementation GB3836.1-2000 explosive gas condition with electric set with part1: General request and GB3836.2-2000 explosive gas condition with electric set with part2: Flameproof D, also along with IEC79-1, BS4683 and EN50018, flame-proofExplosion-proof marked Exd, practical in the coal mine with combustible gas (methane) and air condition of explosive gas or coal dust explosive damageAs the selection and layout of the traction weight machine set with the driving forceYJ ordinary practical on the condition of the mixed explosive gas contentYBJ with explosion-proof winch motor features and use:YBJ series motor is the driver for the coal mine roadway harvesters and dispatching winch or the ground base winch machine form a complete set of special motor traction weights
This series electric machinery subject to high quiet, beautiful shape, reliable operation, long service life, the function is exquisite, settle use convenient repair
Characteristics:

YBJ winch use explosion-proof motor skills parameters
Order of merit: insulation class F
Additional voltage: 380/660 660/1140V
Synchronous speed: protective order of merit: IP55
YBJ with explosion-proof winch motor usage conditions:

(1) 1000m elevation not catch

(2) At the end of the air temperature with HOU innovation, as is generally not overtake: 20 to + 40℃

3) Largest air relative humidity to be driven over 95% (when the temperature is + 25℃)

(4) YBJ explosion-proof motor for coal mine, YJ series is normal, for the explosion-proof conditions on the ground


YBJ with explosion-proof winch motor work way: S1

No foot) YBJ coal mine hoist with flame-proof three-phase asynchronous motor

With foot) YBJ coal mine hoist with flameproof three-phase asynchronous motor

YBJ winch use explosion-proof motor type:

For example: YBJ-255-4

Y: Asynchronous motor
B: Flameproof for ordinary (O)
J: Winch with 4: number

YBJ explosion-proof motor using electrical conditions
