YB2 series flameproof three phase asynchronous motor explosion-proof motor explosion-proof motor explosion-proof motor factory price
Product Name: | YB2 series flameproof three phase asynchronous motor explosion-proof motor explosion-proof motor explosion-proof motor factory price |
Published: | 2011-06-20 |
Product Type: | YB2 Series |
Product Description: | YB2 series flameproof three phase asynchronous motor explosion-proof motor explosion-proof motor explosion-proof motor factory price A, YB2 series flameproof three phase asynchronous motor explosion-proof electrical Overview YB2 series flameproof three-phase asynchronous motor is the upgrading of our YB series of basic series explosion-proof motor, this series featured by small size, light weight, nice appearance, safe and reliable operation, long life, excellent performance, installation easy maintenance. YB2 series flameproof three phase asynchronous motor explosion-proof motor power rating, installation dimensions conform to International Electrotechnical Commission (IEC) standard, which corresponds to the same relationship with the German standards DIN42673, is conducive to supporting the export of equipment and the introduction of equipment, spare parts. YB2 series flameproof three phase asynchronous motor explosion-proof motor explosion-proof performance in line with GB3836.1-2000 "Electrical equipment for explosive gas atmospheres Part 1: General requirements" and GB3836.2-2000 "Electrical apparatus for explosive gas atmospheres Part 2 Part: Flameproof "d" "shall also comply with IEC79-1, BS4683 and EN50018 requirements, made flameproof. Ex logo ExdI, ExdIIAT4, ExdIIBT4, explosive gas mixtures for the existence of the place. ExdI methane or coal dust for the explosive mixture of non-existence of mining face coal mine environment. ExdIIAT4 used for the factory class A-II, temperature class T1, T2, T3 and T4 groups exist explosive gas mixture environment. ExdIIBT4 used for the factory class II B, temperature classification T1, T2, T3 and T4 groups there is an explosive gas mixture environment. YB2 series motors in the basic foundation, but also can be made YB2-W Outdoor, YB2-WFI-type anti-corrosion and other outdoor medium climate conditions. Ex marks the meaning motor Representative of the significance of the motor model Second, YB2 series flameproof three phase asynchronous motor explosion-proof motor structure that 2.1 The structure of the motor of the explosive ExdI, ExdIIAT4, ExdIIBT4. 2.2 The main motor class for shell protection IP55. 2.3 motor cooling method is IC411. 2.4 Class F motor insulation class, temperature rise of stator winding margin, long life. 2.5 motor has a cylindrical shaft, through linkage, or gear drive. 2.6 motor stator winding enamelled round copper wire of high strength, and by the vacuum pressure Impregnation processed into an integrated whole, winding and insulation has good electrical, mechanical, moisture resistance and thermal stability. 2.7 motor with cast aluminum structure, the rotor dynamic balance by check, the motor running smoothly with small vibration and low noise. 2.8 motor stator and rotor punching with high permeability, low loss high-quality electrical steel, motor low loss, high efficiency. 2.9 motor bearings use special low-vibration motor, low noise, bearings, frame size 160 and below with double sealed bearings, the shaft end with wave spring washers, to moderate the pressure by the bearing, the motor running effectively suppress the vibration and noise, frame size 180 and above, with inside and outside the cover structure, and parts used in the bearing ring axially fixed, to effectively prevent axial movement of the motor rotor. To enable safe and reliable operation of the motor, frame size 180 and above, set the motor bearing structure of a note row of oil installations, frame size 250 and above, motors, reserved bearing temperature monitoring sensor location. 2.10 motor fan, fan cover: Frame numbers 280 and below the fan motor using anti-static plastic, and its moment of inertia is small, low loss, frame size 315 and above, cast aluminum or welded steel plate fan, light weight, high strength, full range of fan and shaft coupling, reliable operation. Wind shield for the steel structure, a certain size to prevent foreign matter get the maximum under the premise of the ventilation area, the wind direction open. |
