| 隔爆型錐形轉(zhuǎn)子電動(dòng)機(jī)是我廠最新設(shè)計(jì)的IIB、IIC級(jí)防爆電機(jī)。 BZD系列電機(jī)主要作為防爆電動(dòng)葫蘆的起升電動(dòng)機(jī)和防爆電動(dòng)卷?yè)P(yáng)機(jī)及其它設(shè)備的帶制動(dòng)動(dòng)力之用。BZDY系列電機(jī)主要作為防爆電動(dòng)葫蘆的運(yùn)行電機(jī)和單梁行車的驅(qū)動(dòng)裝置配套之用。 BZD系列和BZDY系列電動(dòng)機(jī)按國(guó)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(jí)別IIB、IIC級(jí)，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(chǎng)所。 電動(dòng)機(jī)工作制為S4，基準(zhǔn)負(fù)載持續(xù)率為25%，每小時(shí)等效起動(dòng)次數(shù)為120次。 額定電壓： 380V 額定頻率： 50Hz 防護(hù)等級(jí)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. | |||
