中空玻璃生產(chǎn)線打膠難題：壓力夠卻打不滿膠？這樣排查就解決

　　Difficulty in gluing insulating glass production line: Can't glue under enough pressure? This way of investigation will solve the problem

　　在中空玻璃生產(chǎn)線的打膠環(huán)節(jié)，不少一線操作人員都遇到過這樣的棘手情況：設(shè)備壓力明明能正常起來，卻始終打不上膠，或者膠量填不滿玻璃縫隙。這種問題不僅影響封膠質(zhì)量，導(dǎo)致中空玻璃密封性能不達(dá)標(biāo)，還會(huì)耽誤生產(chǎn)進(jìn)度。其實(shí)核心原因多集中在壓力傳遞環(huán)節(jié)的三個(gè)關(guān)鍵部位，只要按“先查壓力匹配、再查部件動(dòng)作、最后查控制元件”的順序排查，就能快速解決。今天就專門科普這個(gè)實(shí)用排查技巧，幫大家輕松應(yīng)對(duì)“壓力夠卻打不滿膠”的故障。

　　In the gluing process of the insulated glass production line, many frontline operators have encountered such a tricky situation: although the equipment pressure can be normally increased, the glue cannot be glued or the amount of glue cannot fill the gaps in the glass. This problem not only affects the quality of the sealing adhesive, resulting in substandard sealing performance of the insulated glass, but also delays the production schedule. In fact, the core reasons are mostly concentrated in the three key parts of the pressure transmission process. As long as the order of "checking pressure matching first, then checking component action, and finally checking control components" is followed, it can be quickly solved. Today, we will specifically popularize this practical troubleshooting technique to help everyone easily deal with the problem of "enough pressure but not enough glue".

　　先跟大家理清核心邏輯：打膠機(jī)的膠液輸送靠壓力驅(qū)動(dòng)，看似“壓力夠”，實(shí)則可能是“顯示壓力”與“實(shí)際有效壓力”不匹配，或是壓力傳遞過程中出現(xiàn)卡滯。我們的排查重點(diǎn)就是驗(yàn)證這兩個(gè)核心點(diǎn)，具體圍繞三個(gè)關(guān)鍵部件展開——液壓站、增壓缸、配電柜中間繼電器，按從易到難的順序操作，不用盲目拆解設(shè)備。

　　First, let me clarify the core logic: the glue delivery of the glue machine is driven by pressure, which may seem like "enough pressure", but in reality, it may be due to a mismatch between the "displayed pressure" and the "actual effective pressure", or a jamming during the pressure transmission process. Our focus of investigation is to verify these two core points, specifically focusing on three key components - hydraulic station, booster cylinder, and intermediate relay in the distribution cabinet. Operate in order from easy to difficult, without blindly disassembling the equipment.

　　第一步，先查液壓站壓力是否匹配。首先找到設(shè)備后方的液壓站，觀察液壓站上的指針壓力表，記錄當(dāng)前的實(shí)際壓力值；同時(shí)對(duì)照設(shè)備觸摸屏上設(shè)定的壓力值，看兩者是否一致。這一步是排除“虛假壓力”的關(guān)鍵——如果指針表壓力與觸摸屏設(shè)定壓力不相符，說明液壓站壓力調(diào)節(jié)或壓力傳感器存在問題，后續(xù)即便顯示壓力夠，實(shí)際也無法驅(qū)動(dòng)膠液足額輸送；如果兩者數(shù)值一致，再進(jìn)入下一步排查。

　　The first step is to check if the hydraulic station pressure matches. Firstly, locate the hydraulic station behind the equipment, observe the pointer pressure gauge on the hydraulic station, and record the current actual pressure value; Simultaneously compare the pressure values set on the touch screen of the device to see if they are consistent. This step is the key to eliminating "false pressure" - if the pressure on the pointer gauge does not match the set pressure on the touch screen, it indicates that there is a problem with the hydraulic station pressure regulation or pressure sensor. Even if the pressure is displayed as sufficient in the future, it will not be able to drive the full delivery of the adhesive; If the two values are consistent, proceed to the next step of investigation.

　　第二步，檢查增壓缸是否正常動(dòng)作。增壓缸是壓力傳遞的核心部件，負(fù)責(zé)將液壓站的壓力放大后傳遞給膠液輸送系統(tǒng)。如果液壓站壓力匹配，但仍打不滿膠，就重點(diǎn)觀察增壓缸是否能正常升起和降下。如果增壓缸動(dòng)作卡頓、無法正常升降，哪怕液壓站壓力夠，也無法形成有效輸送壓力，自然打不滿膠。此時(shí)先確認(rèn)增壓缸無機(jī)械卡滯，若動(dòng)作異常，就需要進(jìn)一步檢查控制增壓缸動(dòng)作的元件。

　　Step two, check if the booster cylinder is functioning properly. The booster cylinder is the core component for pressure transmission, responsible for amplifying the pressure of the hydraulic station and transmitting it to the glue conveying system. If the pressure of the hydraulic station matches, but the glue is still not enough, focus on observing whether the booster cylinder can rise and fall normally. If the action of the booster cylinder is stuck and unable to rise and fall normally, even if the hydraulic station pressure is sufficient, effective conveying pressure cannot be formed, and the glue will naturally not be filled. At this point, first confirm that there is no mechanical jamming in the booster cylinder. If the action is abnormal, further inspection of the components controlling the action of the booster cylinder is required.

　　第三步，排查配電柜中間繼電器。如果前面兩步都正常，問題大概率出在控制環(huán)節(jié)的中間繼電器上。打開設(shè)備配電柜，里面有對(duì)應(yīng)增壓缸動(dòng)作的四組中間繼電器，分別控制“一組升、一組降、三組升、二組降”。操作時(shí)啟動(dòng)打膠程序，觀察這四組繼電器的指示燈——如果某組繼電器對(duì)應(yīng)的動(dòng)作（比如增壓缸升）無法完成，且該繼電器指示燈不亮，就說明這個(gè)中間繼電器出現(xiàn)故障，無法傳遞控制信號(hào)，導(dǎo)致增壓缸無法正常動(dòng)作。解決方法很簡(jiǎn)單，直接更換故障的中間繼電器即可。

　　Step three, check the intermediate relay in the distribution cabinet. If the first two steps are normal, the problem is likely to be in the intermediate relay of the control link. Open the equipment distribution cabinet, there are four sets of intermediate relays corresponding to the action of the booster cylinder, which control "one set of rise, one set of fall, three sets of rise, and two sets of fall" respectively. Start the glue application program during operation and observe the indicator lights of these four sets of relays. If the corresponding action of a certain set of relays (such as the booster cylinder lifting) cannot be completed and the indicator light of that relay is not on, it indicates that the intermediate relay has a fault and cannot transmit control signals, causing the booster cylinder to fail to operate normally. The solution is simple, simply replace the faulty intermediate relay.

　　這里給大家補(bǔ)充幾個(gè)實(shí)操注意事項(xiàng)：一是排查前務(wù)必?cái)嚯娀蜴i定設(shè)備，尤其是打開配電柜時(shí)，避免觸電或設(shè)備意外啟動(dòng)；二是觀察液壓站壓力時(shí)，要等壓力穩(wěn)定后再讀數(shù)，避免瞬時(shí)壓力波動(dòng)造成誤判；三是更換中間繼電器時(shí)，要注意型號(hào)匹配，更換后擰緊接線端子，防止接觸不良；四是排查完成后，先空載測(cè)試增壓缸動(dòng)作和壓力傳遞，再進(jìn)行打膠作業(yè)。

　　Here are a few practical precautions for everyone: First, be sure to turn off the power or lock the equipment before troubleshooting, especially when opening the distribution cabinet, to avoid electric shock or accidental equipment startup; Secondly, when observing the pressure of the hydraulic station, wait for the pressure to stabilize before reading to avoid misjudgment caused by instantaneous pressure fluctuations; Thirdly, when replacing the intermediate relay, attention should be paid to model matching. After replacement, tighten the connecting wire terminals to prevent poor contact; The fourth step is to conduct a no-load test on the action and pressure transmission of the booster cylinder after the investigation is completed, and then proceed with the gluing operation.

　　日常生產(chǎn)中，也可以通過兩個(gè)小技巧提前預(yù)防這類故障：一是定期校準(zhǔn)液壓站壓力表和觸摸屏壓力參數(shù)，確保壓力顯示精準(zhǔn)；二是定期檢查增壓缸的潤滑狀態(tài)，避免機(jī)械卡滯，同時(shí)查看配電柜內(nèi)中間繼電器的接線是否牢固，防止振動(dòng)導(dǎo)致松動(dòng)。這些基礎(chǔ)維護(hù)能大幅減少壓力傳遞類故障的發(fā)生。

　　In daily production, two small tips can also be used to prevent such failures in advance: first, regularly calibrate the hydraulic station pressure gauge and touch screen pressure parameters to ensure accurate pressure display; The second is to regularly check the lubrication status of the booster cylinder to avoid mechanical jamming, and at the same time, check whether the wiring of the intermediate relay in the distribution cabinet is firm to prevent loosening caused by vibration. These basic maintenance can significantly reduce the occurrence of pressure transmission failures.

　　“壓力夠卻打不滿膠”看似矛盾，實(shí)則是壓力傳遞環(huán)節(jié)的小問題。對(duì)一線操作人員來說，掌握“液壓站→增壓缸→中間繼電器”的排查邏輯，就能快速定位問題、解決故障，減少生產(chǎn)線停擺時(shí)間。希望這次科普能幫到大家，在日常操作中更好地應(yīng)對(duì)這類生產(chǎn)難題。如果更換繼電器后仍有異常，可進(jìn)一步檢查增壓缸密封件是否損壞，或聯(lián)系設(shè)備廠家技術(shù)支持。

　　The contradiction of 'enough pressure but not enough glue' may seem contradictory, but it is actually a small problem in the pressure transmission process. For frontline operators, mastering the troubleshooting logic of "hydraulic station → booster cylinder → intermediate relay" can quickly locate problems, solve faults, and reduce production line downtime. I hope this science popularization can help everyone better cope with such production difficulties in daily operations. If there are still abnormalities after replacing the relay, you can further check whether the seal of the booster cylinder is damaged, or contact the technical support of the equipment manufacturer.
