防爆電(diàn)機鐵(tiě)芯故(gù)障有(yǒu)幾種?其危害是什麽(me)?

防爆電機鐵(tiě)芯(xīn)的(de)好(hǎo)與壞(huài)，對整台(tái)防(fáng)爆電(diàn)機的質量(liàng)起着(zhe)至關重要(yào)的作用。鐵(tiě)芯質(zhì)量差， 防(fáng)爆(bào)電(diàn)機(jī) 的cos要(yào)降低(dī)；因鐵損耗(hào)增加，效率也要(yào)降低(dī)；因空載電(diàn)流大(dà)，負載電流(liú)随(suí)之(zhī)增(zēng)大，溫升(shēng)也要升高(gāo)；電磁(cí)噪聲要增加；毛(máo)刺大、疊(dié)壓不齊(qí)，對絕(jué)緣有(yǒu)直接(jiē)損傷，是繞(rào)組故障的禍根。爲(wèi)了(le)防止(zhǐ)因鐵芯質(zhì)量差，絕(jué)緣易受(shòu)損傷，制造廠不得(dé)不采取消極(jí)的措施--增(zēng)加主(zhǔ)絕緣厚(hòu)度，浪費(fèi)材料，提(tí)高了防爆電機成本，散(sàn)熱(rè)也差，而轉子(zǐ)鐵芯菱形(xíng)還影響動平衡(héng)的精(jīng)度。這個(gè)是防爆(bào)電機(jī)鐵芯故障(zhàng)的(de)危害。 防爆電(diàn)機 鐵(tiě)芯的故障(zhàng)，嚴格(gé)的講，指的(de)是鐵芯(xīn)制造質(zhì)量。它(tā)由毛(máo)刺大(dà)、疊壓不齊、裝壓(yā)不緊(jǐn)及變形四(sì)種類(lèi)型構(gòu)成(圖(tú)\文 xiaojikuaipao.top/ )。
中譯(yì)英：
explosion proof motor iron core of good and bad, the whole sets of explosion-proof motor quality plays a crucial role in. the core of poor quality, explosion-proof motor cos to reduce; because the iron losses increase, efficiency to decrease; because of the no-load current, load current increases, the temperature rise can be increased; electromagnetic noise will increase; burr, laminated not neat, the insulation has direct damage, is the bane of winding fault. in order to prevent poor quality for core, insulated vulnerable to injury, factory had to take measures to increase negative -- main insulation thickness, material waste, improves the explosion-proof motor cost, heat is poor, and the rotor core diamond also affects the dynamic balance precision. this is the explosion-proof motor iron core fault hazard. explosion proof motor iron core fault, strictly speaking, refers to the core manufacturing quality. it consists of burr, laminated not neat, loading is not pressed tightly and deformation of four types.
