| 隔爆型錐形轉(zhuǎn)子電動機是我廠最新設(shè)計的IIB、IIC級防爆電機。 BZD系列電機主要作為防爆電動葫蘆的起升電動機和防爆電動卷揚機及其它設(shè)備的帶制動動力之用。BZDY系列電機主要作為防爆電動葫蘆的運行電機和單梁行車的驅(qū)動裝置配套之用。 BZD系列和BZDY系列電動機按國家標(biāo)準(zhǔn)GB3836．2-83《性環(huán)境用防爆電氣設(shè)備隔爆型電氣設(shè)備“d”》的要求，制成隔爆型，防爆標(biāo)志dII BT4、dII CT4，適用于工廠具有級別IIB、IIC級，溫度組別T1～T4組的可燃性氣體、蒸氣與空氣形成的性氣體混合物的場所。 電動機工作制為S4，基準(zhǔn)負載持續(xù)率為25%，每小時等效起動次數(shù)為120次。 額定電壓： 380V 額定頻率： 50Hz 防護等級IP44或IP54 | |||
| The motor with conic rotor is the lateat IIB and IIC one designed byour works. The BZD range of motors is used as the lifting motor of explosion- proofelectric hoist and the driving equipment of explosion- proof windingengine and other machinery. The BZDY range of motors is as the runmotor of explosion-proof hoist or matched with the driving device ofsingle carrier. The explosion-proof characteristic GB3836.2-2000 << Flame-proof "d"- - ElectricalApparatus Used in Explosive Atmosphere Part 2 >> can be made into flame-proof type. This range ofmotors, whose explosive marking is dI, dIIAT4, dIIBT4 and dIICT4, canrespectively used in places where there are flammable gas and themixture of the vapour and air in the coal minging and factory wherethe protection degree is IIA,IIB or IIC and temperature is T1-T4. Duty type is S4 whose the basic load continuity is 25% and theequivalent starting times is 120 every hour. Rated voltage: 380V. Rated frequency: 50Hz. Protection grade: IP44 or IP54. | |||
