為什么防爆電機(jī)會啟動困難,如何解決?


防爆電機(jī)啟動困難,加負(fù)載后不能升至額定轉(zhuǎn)速的原因和解決辦法如下:防爆電機(jī)電源電壓低:電源電壓太低時,與供電部門聯(lián)系解決,若線路壓降大,可改用粗電纜;\型轉(zhuǎn)子開焊或斷條:用開口變壓器或其他儀器檢查。對銅條轉(zhuǎn)子可以補(bǔ)焊,鑄鋁轉(zhuǎn)子則宜重鑄。繞線轉(zhuǎn)子一相斷路:用校驗(yàn)燈、萬用表找出斷路處后修復(fù)。繞線轉(zhuǎn)子電刷或啟動變阻器接觸不良:檢修電刷與啟動變阻器的接觸部位。定子繞組匝數(shù)多和定子繞組節(jié)距不合適:調(diào)整定子繞組。定、轉(zhuǎn)子繞組有局部線圈接錯或接反:按設(shè)計資料復(fù)查,重新接線。防爆電機(jī)繞線轉(zhuǎn)子電刷與集電環(huán)接觸不良:調(diào)整刷壓,按集電環(huán)外圓弧度磨電刷接觸表面,以增加接觸面積(圖\文brfr.com.cn/)。

Explosion proof motor start difficulties, adding loads cannot be rated speed to cause and solution is as follows: explosion-proof motor with low power supply voltage: power when the voltage is too low, and the power supply departments to solve, if the line voltage drop is big, can use thick cable. Cage type rotor welding or breaking: opening of transformer or other instrument check. For copper strip rotor can be welding, cast aluminum rotor are advised to recast. Wound rotor phase breaker: check lamp, multimeter identify circuit after repair. Wound rotor brush or starting rheostat bad contact: maintenance of the brush and the contact position of starting rheostat. Stator winding, and the stator winding pitch: not suitable adjustment of stator winding. A local coil, rotor winding fault or reverse : according to design data review, new wiring. Explosion proof motor winding rotor collector ring brush and bad contact: adjust the brush pressure, according to the collector ring circular arc grinding brush contact surface, so as to increase the contact area.
