Analysis of the two common faults -- "leakage" and "overheating" reason:

卷?yè)P機在長(cháng)時(shí)間工作的情況下經(jīng)常會(huì )發(fā)生漏油和過(guò)熱的現象。卷?yè)P機漏油，要注意觀(guān)察油封部位，檢查油封是否有龜裂、內唇口有無(wú)開(kāi)裂或翻邊。還要注意“三個(gè)檢查”：檢查油封與主軸結合面有否劃傷與缺陷，存在劃傷與缺陷的應予更換。檢查回油是否暢通，回油不暢使曲軸箱壓力過(guò)高導致油封漏油或脫落，必須保證回油管最小管徑，并且不扭曲、不折彎，回油順暢。檢查油封、箱體配合尺寸，不符合標準的予以更換。

Hoist in long time working conditions often spill and overheating phenomenon. The oil spill, to observe the seal parts, check the oil seal if there is crack, inner lip with or without cracking or flange. Also note that the "three check": check the oil seal combined with the main surface has scratches and defects, there are scratches and defects should be replaced. Check back to the oil flow, poor oil return to the crankcase pressure caused by high seal leak or fall off, must ensure that the minimum diameter of the oil return pipe, and no distortion, no bending, oil return smoothly. Check the oil seal, the box with the size, does not accord with a standard to be replaced.

在卷?yè)P機的日常操作中，會(huì )因卷?yè)P機的長(cháng)時(shí)間超負荷運作而出現卷?yè)P機過(guò)熱故障。常見(jiàn)的發(fā)熱部位有兩處：卷?yè)P機減速機出氣口溫度過(guò)高；運轉部位發(fā)燙。

In the daily operation of hoist, because of long time hoist overload operation and the emergence of the overheat fault. Heating of common site has two parts: hoist reducer outlet temperature is too high; running parts of hot.
