SF89R59減速機(jī)電機(jī)安裝注意事項(xiàng):
注意要將設(shè)備擺放平穩(wěn),固定好地腳和法蘭,并精確校準(zhǔn)直接連接的聯(lián)軸器。防止安裝不當(dāng)造成旋轉(zhuǎn)頻率和雙倍電源頻率的諧振。用手轉(zhuǎn)動(dòng)轉(zhuǎn)子,檢查有無(wú)異常摩擦聲。在未聯(lián)接外部設(shè)備的狀態(tài)下檢查轉(zhuǎn)向。齒輪減速電機(jī)
SF89R59減速機(jī)電機(jī)安裝在塵埃灰屑或水滴等較多處,會(huì)對(duì)本機(jī)器會(huì)產(chǎn)生不良影響時(shí),請(qǐng)用覆蓋物蓋住,覆蓋物不要密封,必須留有通氣口(若工作環(huán)境粉塵密聚或需要防水機(jī)種,購(gòu)買時(shí)請(qǐng)?zhí)貏e說(shuō)明)。
嚴(yán)禁在SF89R59減速機(jī)電機(jī)的周圍放置可燃物。否則有可能會(huì)導(dǎo)致火災(zāi)。
嚴(yán)禁在SF89R59減速機(jī)電機(jī)的周圍放置阻礙通風(fēng)的障礙物。否則,可能會(huì)因冷卻不暢、異常過(guò)熱而導(dǎo)致燙傷、火災(zāi)等情況。
嚴(yán)禁站立在SF89R59減速機(jī)電機(jī)上面或懸掛其上。否則有可能會(huì)導(dǎo)致受傷。
請(qǐng)勿赤手觸摸SF89R59減速機(jī)電機(jī)的軸端部、內(nèi)徑部的鍵槽。否則有可能會(huì)導(dǎo)致受傷。自鎖減速機(jī)
安裝完后,檢查電機(jī)是否通風(fēng)良好。且確認(rèn)沒(méi)有鄰近設(shè)備、表面或直射陽(yáng)光向電機(jī)額外輻射熱量。
SF89R59減速機(jī)電機(jī)電流異常解決方案:
SF89R59減速機(jī)電機(jī)外殼帶電:電源線碰機(jī)殼,且絕緣皮破損,電源線修復(fù);繞組受潮、絕緣老化、接地裝置壞,維修換定子線圈,重裝接地線。
SF89R59減速機(jī)電機(jī)三相電流不平衡:三相電壓不平衡,維修電源電壓;線圈部分線圈短路,更換定子線圈;線圈內(nèi)有一個(gè)線苞嵌反,更換定子線圈。
SF89R59減速機(jī)電機(jī)電流過(guò)大:電源電壓偏差大,維修電源電壓;接法錯(cuò)誤,應(yīng)是Y接法錯(cuò)用為△接法,接法更正;更換電機(jī),定轉(zhuǎn)子擦;負(fù)載過(guò)大,選用大容量電機(jī)或減小負(fù)載。伺服電機(jī)蝸輪蝸桿減速機(jī)
