ATEX explosion proof moor for mine
IEC: 63-355 ATEX certification
Exd1 and Exd11BT4
ATEX YB2 YB3 YBK2 YBK3 YBF2explosion proof moor for mine
Attribute and usage
YB2 ranges of a few-period induction motors are flame-proof motors acquired by renewal and technology-altering of YB ranges of motors. The performances of the items have arrive up to sophisticated international specifications.
The motors have the benefits of larger performance, power conserving, greater locked-rotor torque, decrease sound, scaled-down vibration, risk-free and dependable operation and lovely look, and so forth. The outputs, mounting dimensions and their corresponding interactions comply with IEC expectations.
YB2 collection electric powered motors are designed and produced into explosion evidence sort and the explosion evidence house conforms to China Countrywide CZPTs: GB3836.1-2000 CZPTal Apparatus for Explosive Gas Atmospheres-CZPT Requirements. GB3836.two-2000 CZPTal Apparatus for Explosive Gasoline Atmospheres- Explosion proof Enclosure d and expectations IEC79-one, BS4683 and EN50018. ExdI- protected for use in the non-mining surfaces of underground coal mines where the explosive mixtures of methane or coal-dust are existing. ExdIIAT4 – risk-free for use in crops exactly where the explosive mixtures of IIA Class, TI, T2, T3 or T4 are present. ExdIIBT4 – risk-free for use in plants the place the explosive mixtures of IIB Class, TI, T2, T3 or T4 are present. ExdIICT4 – risk-free for use in vegetation in which the explosive mixtures of IIC Course, TI, T2, T3 or T4 are existing.

1. You should show the motor type, rated output, rated voltage, rated frequency, synchronous speed, Explosion proof Mark, mounting type, rotation course(look at from the shaft extension side)Use of the surroundings(indoor or outside)If the person havn’t level out the rotation and atmosphere, normailly we believe is CW roration and used indoor.
2. When user have unique requirments, For instance: Dispose the stator, bearing explosion evidence and bearing temperature sensors, space heater, Plateau use, specical frequency, mounting measurement modify, particular output, the person should, order can be confirm after signing the complex arrangement with engneering department.
three. This assortment of motor can also be produced into Variable-Frequency motors, the range of frequency of which is -100HZ, the output and general proportions ought to be confirm individually.
There are E x d I and ExdIIBT4 variety in YB2 ranges of a few-period asynchronous explosion proof motor in accordance to the necessity of the software. The efficiency of the basic safety of the products is confirming to the regular of GB3836.one-2000<> and GB3836.2-2000<>, This ranges of products are suitable for the non-mining functioning region in underground mine or the place there are the explosive gasoline combination in factories
