在濟(jì)南的大街小巷，卷簾門作為商鋪、車庫的 “衛(wèi)士”，日復(fù)一日承受著頻繁升降的考驗。時間一長，開關(guān)時的卡頓、異響逐漸顯現(xiàn)，這時就需要給它 “喂” 點潤滑油來恢復(fù)順滑。不過，給卷簾門上油可不是隨意涂抹，掌握正確的方法和關(guān)鍵點位，才能讓它重?zé)`活。

　　In the streets and alleys of Jinan, rolling shutter doors, as the "security guards" of shops and garages, are subjected to frequent lifting and lowering tests day after day. Over time, the stuttering and abnormal noise of the switch gradually become apparent, and it is necessary to "feed" it some lubricating oil to restore smoothness. However, oiling the rolling shutter door is not something to apply casually. Only by mastering the correct methods and key points can it regain its flexibility.

　　準(zhǔn)備工作：工具與油品的雙重把關(guān)

　　Preparation work: Dual control of tools and oil products

　　在動手潤滑前，先備好合適的工具與潤滑油。工具方面，一把小毛刷用于清理灰塵雜物，一支長嘴油壺能精準(zhǔn)控制潤滑油的流向，干凈的抹布則負(fù)責(zé)擦拭多余油漬。潤滑油的選擇也有講究，應(yīng)避免使用黏稠的黃油，因為它容易吸附灰塵形成油泥，反而加重卡頓；建議使用流動性好、抗磨損的專用卷簾門潤滑油，或是輕質(zhì)的機(jī)油，確保潤滑效果持久。

　　Before starting to lubricate, prepare suitable tools and lubricating oil. In terms of tools, a small brush is used to clean dust and debris, a long mouthed oil pot can accurately control the flow of lubricating oil, and a clean cloth is responsible for wiping off excess oil stains. The selection of lubricating oil also has its own considerations. It is advisable to avoid using viscous butter, as it can easily absorb dust and form sludge, which can worsen the lag; It is recommended to use specialized rolling shutter door lubricating oil with good fluidity and wear resistance, or lightweight engine oil, to ensure long-lasting lubrication effect.

　　關(guān)鍵部位一：卷軸軸承的深度滋養(yǎng)

　　Key part one: Deep nourishment of scroll bearings

　　卷簾門的卷軸軸承是承擔(dān)整扇門重量與升降摩擦的核心部位，也是需要潤滑的 “重災(zāi)區(qū)”。找到卷軸兩端暴露在外的軸承，先用毛刷仔細(xì)掃去表面堆積的塵土、鐵屑等雜質(zhì)，確保軸承表面干凈。接著，將油壺嘴對準(zhǔn)軸承與軸桿的縫隙，緩慢注入潤滑油，讓油順著縫隙滲透到軸承內(nèi)部。為保證充分潤滑，可一邊注油，一邊手動轉(zhuǎn)動卷軸，使?jié)櫥途鶆蚍植荚谳S承的各個接觸面。每側(cè)軸承少滴入 5 - 8 滴潤滑油，老舊或卡頓嚴(yán)重的軸承可適當(dāng)增加用量。

　　The roller bearing of the rolling shutter door is the core part that bears the weight and lifting friction of the entire door, and it is also the "hardest hit area" that needs lubrication the most. Find the exposed bearings at both ends of the scroll, and carefully sweep away the accumulated dust, iron filings, and other impurities on the surface with a brush to ensure that the bearing surface is clean. Next, align the oil spout with the gap between the bearing and the shaft, slowly inject lubricating oil, and allow the oil to penetrate into the interior of the bearing through the gap. To ensure sufficient lubrication, the oil can be injected while manually rotating the spool to evenly distribute the lubricating oil on all contact surfaces of the bearing. At least 5-8 drops of lubricating oil should be dripped onto each side of the bearing. For old or severely stuck bearings, the amount can be increased appropriately.

　　關(guān)鍵部位二：鏈條與齒輪的 “咬合呵護(hù)”

　　Key part two: "bite care" of chain and gear

　　若卷簾門采用鏈條傳動，鏈條與齒輪的潤滑同樣重要。觀察鏈條表面，若出現(xiàn)干澀發(fā)白、銹跡或卡頓，就需及時保養(yǎng)。先用抹布擦拭鏈條，去除表面污垢，再將潤滑油沿著鏈條的鏈節(jié)縫隙逐一滴入，確保每個轉(zhuǎn)動關(guān)節(jié)都能得到潤滑。對于齒輪，可將油滴在齒輪的齒牙上，然后手動推拉卷簾門，讓齒輪轉(zhuǎn)動起來，使?jié)櫥统浞指采w咬合部位。在這個過程中，要特別注意避免潤滑油滴落在門簾上，若不慎滴落，需立即用抹布擦凈，防止油漬污染。

　　If the rolling shutter door adopts chain drive, lubrication of the chain and gears is equally important. Observe the surface of the chain. If there is dryness, whitening, rust, or jamming, timely maintenance is necessary. First, wipe the chain with a cloth to remove surface dirt, and then drip lubricating oil along the gaps between the chain links one by one to ensure that each rotating joint is lubricated. For gears, oil can be dripped onto the teeth of the gear, and then the rolling shutter door can be manually pushed and pulled to make the gear rotate, so that the lubricating oil fully covers the meshing area. During this process, special attention should be paid to avoiding lubricating oil from dripping onto the door curtain. If it accidentally drips, it should be wiped clean immediately with a cloth to prevent oil contamination.

　　關(guān)鍵部位三：導(dǎo)軌與滑輪的 “滑行助力”

　　Key part three: "Sliding assistance" of guide rails and pulleys

　　卷簾門的導(dǎo)軌和滑輪承擔(dān)著引導(dǎo)門體上下滑動的功能，一旦干澀，就會導(dǎo)致升降不暢甚脫軌。檢查導(dǎo)軌內(nèi)部，若發(fā)現(xiàn)有灰塵、碎石或干澀痕跡，先用毛刷清理干凈，再沿著導(dǎo)軌的凹槽均勻涂抹一層潤滑油。對于滑輪，可將油滴在滑輪的軸承處，然后多次升降卷簾門，讓滑輪在導(dǎo)軌中滑動，使?jié)櫥途鶆蚍植迹瑴p少摩擦阻力。值得注意的是，導(dǎo)軌兩端的封口處也需少量注油，防止滑輪在此處因缺乏潤滑而卡頓。

　　The guide rails and pulleys of the rolling shutter door bear the function of guiding the door body to slide up and down. Once it becomes dry, it can lead to poor lifting or even derailment. Check the inside of the guide rail. If dust, gravel or dry marks are found, clean them with a brush first, and then apply a layer of lubricating oil evenly along the groove of the guide rail. For pulleys, oil can be dripped onto the bearings of the pulley, and then the rolling shutter door can be raised and lowered multiple times to allow the pulley to slide in the guide rail, ensuring even distribution of lubricating oil and reducing frictional resistance. It is worth noting that a small amount of oil needs to be injected at the sealing points on both ends of the guide rail to prevent the pulley from jamming due to lack of lubrication at this location.

　　收尾工作：細(xì)節(jié)處理與效果檢驗

　　Closing work: Detail processing and effect verification

　　完成關(guān)鍵部位的潤滑后，用干凈抹布擦去卷簾門表面多余的潤滑油，避免吸附灰塵。隨后，反復(fù)升降卷簾門 3 - 5 次，觀察門體運行是否順暢，卡頓、異響是否消失。若仍存在問題，需再次檢查潤滑部位，補(bǔ)充潤滑油或排查是否有其他機(jī)械故障。此外，建議每隔 3 - 6 個月為卷簾門進(jìn)行一次潤滑保養(yǎng)，尤其是在風(fēng)沙較大的季節(jié)過后，及時清理灰塵并補(bǔ)油，讓卷簾門始終保持靈活的工作狀態(tài)，守護(hù)好每一扇門后的與便利。

　　After completing the lubrication of key parts, use a clean cloth to wipe off excess lubricating oil on the surface of the rolling shutter door to avoid dust adsorption. Subsequently, repeatedly lift and lower the rolling shutter door 3-5 times, observing whether the door runs smoothly and whether the jamming and abnormal noise disappear. If the problem still exists, it is necessary to check the lubrication parts again, replenish lubricating oil or investigate whether there are other mechanical faults. In addition, it is recommended to lubricate and maintain the rolling shutter doors every 3-6 months, especially after the windy season. Clean the dust and replenish the oil in a timely manner to keep the rolling shutter doors in a flexible and efficient working state, and protect the safety and convenience behind each door.
