中空玻璃生产线打胶难题：压力够却打不满胶？这样排查就解决

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

　　在中空玻璃生产线的打胶环节，不少一线操作人员都遇到过这样的棘手情况：设备压力明明能正常起来，却始终打不上胶，或者胶量填不满玻璃缝隙。这种问题不仅影响封胶质量，导致中空玻璃密封性能不达标，还会耽误生产进度。其实核心原因多集中在压力传递环节的三个关键部位，只要按“先查压力匹配、再查部件动作、最后查控制元件”的顺序排查，就能快速解决。今天就专门科普这个实用排查技巧，帮大家轻松应对“压力够却打不满胶”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".

　　先跟大家理清核心逻辑：打胶机的胶液输送靠压力驱动，看似“压力够”，实则可能是“显示压力”与“实际有效压力”不匹配，或是压力传递过程中出现卡滞。我们的排查重点就是验证这两个核心点，具体围绕三个关键部件展开——液压站、增压缸、配电柜中间继电器，按从易到难的顺序操作，不用盲目拆解设备。

　　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，先查液压站压力是否匹配。首先找到设备后方的液压站，观察液压站上的指针压力表，记录当前的实际压力值；同时对照设备触摸屏上设定的压力值，看两者是否一致。这一步是排除“虚假压力”的关键——如果指针表压力与触摸屏设定压力不相符，说明液压站压力调节或压力传感器存在问题，后续即便显示压力够，实际也无法驱动胶液足额输送；如果两者数值一致，再进入下一步排查。

　　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，检查增压缸是否正常动作。增压缸是压力传递的核心部件，负责将液压站的压力放大后传递给胶液输送系统。如果液压站压力匹配，但仍打不满胶，就重点观察增压缸是否能正常升起和降下。如果增压缸动作卡顿、无法正常升降，哪怕液压站压力够，也无法形成有效输送压力，自然打不满胶。此时先确认增压缸无机械卡滞，若动作异常，就需要进一步检查控制增压缸动作的元件。

　　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，排查配电柜中间继电器。如果前面两步都正常，问题大概率出在控制环节的中间继电器上。打开设备配电柜，里面有对应增压缸动作的四组中间继电器，分别控制“一组升、一组降、三组升、二组降”。操作时启动打胶程序，观察这四组继电器的指示灯——如果某组继电器对应的动作（比如增压缸升）无法完成，且该继电器指示灯不亮，就说明这个中间继电器出现故障，无法传递控制信号，导致增压缸无法正常动作。解决方法很简单，直接更换故障的中间继电器即可。

　　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.

　　这里给大家补充几个实操注意事项：一是排查前务必断电或锁定设备，尤其是打开配电柜时，避免触电或设备意外启动；二是观察液压站压力时，要等压力稳定后再读数，避免瞬时压力波动造成误判；三是更换中间继电器时，要注意型号匹配，更换后拧紧接线端子，防止接触不良；四是排查完成后，先空载测试增压缸动作和压力传递，再进行打胶作业。

　　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.

　　日常生产中，也可以通过两个小技巧提前预防这类故障：一是定期校准液压站压力表和触摸屏压力参数，确保压力显示精准；二是定期检查增压缸的润滑状态，避免机械卡滞，同时查看配电柜内中间继电器的接线是否牢固，防止振动导致松动。这些基础维护能大幅减少压力传递类故障的发生。

　　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.

　　“压力够却打不满胶”看似矛盾，实则是压力传递环节的小问题。对一线操作人员来说，掌握“液压站→增压缸→中间继电器”的排查逻辑，就能快速定位问题、解决故障，减少生产线停摆时间。希望这次科普能帮到大家，在日常操作中更好地应对这类生产难题。如果更换继电器后仍有异常，可进一步检查增压缸密封件是否损坏，或联系设备厂家技术支持。

　　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.
