Explosion Proof Asynchronous Motor

Listing ID #430293

YB2 Series Explosion Proof Asynchronous Motor (YB2-1) is an efficient device supplied by the company. The YB2 Series Explosion Proof Asynchronous Motor (YB2-1) is used at working places of underground non-digging faces of mines. YB2 Series Explosion Proof Asynchronous Motor (YB2-1) is also used in factories that are involved in gases mixed with explosives. We take special care in ensuring the quality of our YB2 Series Explosion Proof Asynchronous Motor (YB2-1). Type : YB2 series explosion-proof asynchronous motors (No. of motor case : H63-355) Technical Information

• Rated voltage : 380V, 660V, 380660V, 6601140V
• Rated frequency : 50Hz
• Insulation class : Class F
• Grade of protection : IP55
• Way of cooling : IC411
• Installation mode : B3, B5, B35
• Explosion -Proof mark : "Exd I" or "Exd II BT4"
• Features Of Structure The bearing with low vibration and noise, specialized for motor, is used as bearing of motor, double face sealing bearing is adopted for motor case No. 160and below, and wave spring washer is mounted at the extension end of the bearing which can effectively restrain vibration and noise of the motor generated during the running period. Internal and external cover structure for motor case No.180 and above is adopted and retaining ring is used at the extension part of the bearing for axial fixing, which can effectively prevent rotor of the motor from axial motion. For safe and reliable operation of motor, the motor with case No. 180 and above can be equipped with oil injection device on the bearing structure as per the need of client, and the motor with case No. 250 and above, the position of bearing temperature monitoring sensing element is added. Scope Of Application Type YB2 series explosion-proof three-phase asynchronous motors are made into either explosion -proof “ExdI” or explosion -proof“ExdIIBT4” in accordance with its application requirement, the explosion-proof performance complies with specification of GB3836.1-2000. Electrical equipment used at explosive gas environment part 1：General requirement and GB3836.2-2000. Electrical equipment used at explosive gas environment part 2: Explosion-proof Type “d”. Also used at the working place of underground non digging working face of mine and the place of factory containing explosive mixed gases. In case of special requirement from the client, negotiation can be made with the manufacturer.
