本次网络研讨会:为您的VFFS机器提供5 W的预防性维护

会议记录:

艾米丽·布罗根

大家好。感谢您收看今天的网络研讨会，关于立式填封机预防性维护的五个W。我叫Emily Brogan，我是ROVEMA北美地区的市场和销售协调员。今天和我在一起的还有Don Lawrence，他是我们全生命周期服务团队的技术部件和保修专家，以及Shahram Shariff，他是我们的工程经理，负责监督和支持我们的客户和销售团队，为新机器提供工程规范。所以在他们两人之间，我们实际上已经有超过60年的行业经验。这是令人兴奋的。虽然我给每个人一个加入我们的机会，但我想做一些互动。所以我很快就开始调查了。你应该已经看到它跳出来了它会问你在垂直装袋上持续的预防性维护的三个结果对你来说是最重要的。另外，如果你能坚持到最后，我们实际上在最后也会有一个简短的小测验，我们前五个正确的答案会得到一些奖励。 So while you're submitting your answers to the poll before I hand it off to Shahram and Don, First, I want to tell you a quick story. So I want to tell you about a plant that bought a new machine. You know, after installation and培训，它运行得很好。这甚至超出了他们的预期。但第二年之后，几个轮班的主管离开工厂去做其他工作，工厂引进了一些新员工。大约6个月后，公司说，我们正面临一个艰难的季度，我们要求你们将备件费用和库存削减20%。大约一年之后，维修主管退休了一些其他的流程他们以前有但可能不是在正式的SOP中他们变得有点被忽视了。之后还会发生更多的事情。三年后，你还不知道，这台机器的运行速度只有原来的70%也就是设计的目的。你猜这个故事不是关于一个特定的工厂或客户，甚至不是只针对一个垂直表格填封机，你知道，如果我不爱护它，同样的事情也会发生在我的车身上。这就是预防性维护的问题，一些小的改变累积起来就会产生巨大的差异。这就是我们今天来到这里的原因。 That's why I'm so excited to have Don and Shahram on this call with me. So they're actually going to show you how to turn this typical history and machine performance, this story that we hear time and time again, in what you ought to expect, which is consistent production over the life of your machine. So now I'm going to hand it off to Shahram, who is going to start going into these five W's.

Shahram Shariff

谢谢你,艾米丽。正如艾米丽提到的，我叫沙拉姆·沙里夫。我是北美ROVEMA的一名工程师。我们在这里与您分享预防性维护的重要性，特别是那些日常的小的简单维护。这些会给你带来五种很好的结果。这五大成果是什么?最重要的结果就是保持你的能力。你还记得你买机器的原因吗?原因是你想要一定数量的袋子，好的袋子，带出门，日复一日。随着时间的推移，由于各种原因，唐会告诉你这些原因是什么，最初的容量会下降。 We're here to tell you that based on our experience, and our customers experience, preventative maintenance plays the major role in maintaining the original capacity of your machine. The second great outcome would be part longevity. You purchase your machine based on a certain production capacity. Your production capacity hinges around all parts functioning as they should, day in and day out without a hitch. I'm here to share with you that the secret to parts longevity is to take care of your machine by applying these little preventive maintenance tasks. Also, if you happen to have replaced any one of the original parts, with cheaper parts with less expensive parts, then you are risking parts, premature failures, and you might be in for a surprise here and there without even being able to predict it. The third great outcome would be seal integrity. I'm thinking there's nothing worse than people showing up from the end of line, or getting news from the customers or plant manager or so on that all of a sudden 10s of thousands of bags 10s of thousands or hundreds of thousands of pounds of products have gone to waste. Because the seal integrity was compromised. Everybody is going to be looking over your shoulders to look for answers Why? We're here to tell you that as a component of preventive maintenance, if you had cleaned that vertical seal band, you wouldn't be in this situation that you are today. The fourth great outcome would be downtime avoidance. You didn't buy your machine so you can be repairing and stopping it and working on it every day. Just like seal integrity, or did I miss the seal integrity? Let me go back to Yeah. So just like seal integrity, if components especially crucial ones, that means those that touch your bag, day in and day out, are maintained by preventative maintenance. You avoid premature and unexpected failures. Finally on the list of five great outcomes is the lower scrap rate. Just like sealing integrity, if you have a failure, say compromised seals, with or without even you knowing it, it may be too late, you can lose 10s and hundreds of hundreds of thousands of dollars in a jiffy. We're here to share with you that a few simple tasks as Don will go over and he will share with you will avoid this kind of disastrous outcome. Now, in order to be able to to achieve these outcomes, there are foundations with four pillars that are necessary for you to follow. These are what were who and when of what needs to be done to achieve the five great outcomes we touched the maintaining capacity, spare parts longevity, seal integrity, downtime avoidance and lower scrap rate. So the number one pillar is consistency. daily tasks are the most important for a smooth shift. To be sure, SOP's are the key to consistency and follow up even through turnover challenges. Number two is the team member accountability. You need to arm your operators and maintenance people who are your most valuable assets in your plant and arm them with SOPs geared toward factors specific to your operational environment. The third one on the list of foundations is reliable spare parts and reliable wear parts. Again, if you purchase your components, let's say seal band seal jaws, springs, bearings, on and on, at a lower cost, be prepared to be surprised because not all parts are made equal with longevity in mind. And most of the time, I'm afraid you won't even know that the parts are about to fail. Things are going smoothly and all of a sudden you get a surprise. the fourth pillar of the foundations the maintenance schedule. Now that you've got the follow ups, you've got your SOP, you got your team together, you got your SOP, a checklist ready, operator and maintenance buying, you have to own it, incorporate it into your team's daily routine, and follow up, make sure that it becomes a habit, an integral part of your daily operation. With that, I'm going to hand it over to Emily. And here the specifics of these tasks from Don.

艾米丽·布罗根

谢谢你，沙拉姆，带我们了解这些基础，特别是我们可以期待的结果。现在我们实际上想再深入一点了解情况的,我们要通过一些必要的任务,然后接近尾声时,我们会打开一些技术上具体问题在结束时,你应该看到,我把链接给你聊天功能的清单下载。我确实想强调的是，一些困难的产品或更苛刻的打包环境可能需要更频繁的组件维护。这不是一个适用于所有类型的列表，您可能需要在开放行中添加一些额外的特定于模型的任务。如果您对清洁间隔有任何问题，请不要犹豫联系我们。我们非常乐意为您回答这些问题。现在唐·劳伦斯会给我们介绍一下清单上最重要的任务。

劳伦斯不

谢谢你艾米丽。我叫唐·劳伦斯，在ROVEMA工作了30多年。我在ROVEMA的前28年，我在现场服务我们的许多客户，我们注意到了一些事情，我们想和你们分享一些我们注意到的事情是你们的操作，操作人员和维护人员是维护设备和保持设备运行的关键人员。操作员在这方面发挥了很大的作用，他们需要在轮班的前10分钟处理一些日常任务。这将增加你所有的生产力和备件的寿命，只是减少你的停机时间和报废率。所以在设备没有任何问题的情况下设备是正确设置的，操作人员应该能够进行这些操作日常任务在他们转变的前10分钟。他们应该能够在整个一天的剩余时间或剩下的班次中自由运行问题。我们说每个班次的前10分钟，因为我们不知道你是否正在运行两个班次或三个班次，这将因植物而异。所以，我想和你谈论第一，垂直密封区域。这是您的运营商将要照顾的领域之一。但这是一个非常重要的区域，只要垂直密封杆设置成撞击管和正确的薄膜中的垂直密封。我们应该能够打开垂直密封杆拆下垂直密封杆，如果有一个，如果您有一个连续的运动机器，您将有一个垂直密封带，您有一个间歇的运动机，您只需将有一个垂直的密封杆。因此，清洁间歇运动机上的垂直密封杆正好拍摄僵硬的黄铜刷。我们还必须记住，有两种不同类型的黄铜刷子是一个长鬃毛软刷，另一个是短鬃毛粗刷。 And the difference between the two are the softer ones should be used on your Teflon coated co bars and the stiff one should be used on a non Teflon coated sealing surfaces. If you have a continuous motion machine, sometimes customers use Teflon coated seal bands. So these have to be treated a little differently. The seal band once you remove it from the machine, it's easy to clean and then you clean the vertical seal bar itself to remove any of your product or film buildup on the bar. These products and film buildup will create a void on the sealing surface where your seal integrity will be diminished. So, clean the vertical seal bar itself, clean the band, put the band back onto the machine, close it and you're ready to go. Next thing I'd like to talk to you about is your horizontal seal bars. Horizontal seal bars are the same. They need to be clean just as much as the vertical bar, they get product build up, film build up and whatnot. Also the horizontal seal bars can be Teflon coated or just normal coating. Teflon coated requires the soft bristle brush non Teflon coated requires the stiff bristle brush, we must keep in mind that the horizontal seal bars are serrated and product tends to build up in the valleys of these serrations. And it tends to get harder as time goes on. So to clean this you must use your brush and sometimes you may have to get some of the tougher particles out by hand. Which means when I say by hand is that we don't want you to use metal tip or putty knife, steel putty knives, screwdrivers or anything like that to clean the serrations if you have to get in there to clear out some of the tougher products, film deposits or whatever, you must use plastic, okay like a plastic putty knife or something like that these steel, putty knives and screwdrivers and pocket knives and stuff like this razor knives, they will take off your coatings in this will just compound your problems. So we don't want to use these on the sealing surfaces.

艾米丽·布罗根

嘿，唐，当我们谈到这个问题的时候，蒂姆问了我一个问题，他问，黄铜油灰刀可以吗?

劳伦斯不

嗯，是的，你可以用它们，但我们更喜欢你不在下颚上挖掘，你知道，这些将佩戴密封剂或钳口上的保护性密封剂。所以你想对那些人非常小心。什么金属，我们更喜欢你使用塑料。

艾米丽·布罗根

好的,谢谢。

Shahram Shariff

是啊，我想我想说点我的意见。而且，如果你每天都进行这些任务，你可能会除非你生活在一个非常恶劣的环境中，那么你甚至不会出现这种情况你需要刮掉山谷周围的那些颗粒。那是正确的吗?唐，你同意吗?

劳伦斯不

是的，先生。我同意。100%。如果我们这样做，在每班的前10分钟，你永远不会遇到这样的情况，你将不得不挖掘这些。锯齿状的山谷。这就是为什么每次换班的前10分钟意味着你的时间不超过8小时或12小时，这取决于你换班的时间间隔，所以理论上你永远不会出现这些严重的堆积，就像刚才提到的沙赫拉姆。

艾米丽·布罗根

好吧。

劳伦斯不

是的，我们建议使用塑料不会融化当然，我们的下巴，你的温度范围应在大约300至350度的地方，这些机器上使用的大部分胶片最多。好的，所以我们想谈到的下一件事是前封面吧，带刀你的前封杆在所有后来的机器上。刀驻留在前密封杆中。我们希望使用我们用来清洁钳口的相同刷子，是Teflon涂层或非铁氟龙涂层。刀刚用拇指推出，刀片上的锯齿可以用这些钢丝刷，这些黄铜丝刷很容易清洁。你想穿着手套，这些刀具非常尖锐。所以当你清洗这些刀具时需要一个防护手套。只是非常小心他们。它们很热，锐利。所以我们想谈论的下一件事是你的运输带。 And again, this is just happening in the very first 10 minutes of your shift. So they're being cleaned every eight to 12 hours, your belts will get built up with product that rains down from the delivery system above. So this is where we get most of our questions about. How do I control my bag length better? How do I control my registration better, and 90% of the time, these issues are solved just by cleaning these belts. These belts will get slick after so many hours of runtime. If you run for several days without cleaning these belts, they do get slick and this will create bag length issues and/or registration issues. So cleaning these belts, the operator will open the belts up. Don't remove them from the machine. Just open the belt drive system up. Take a clean damp cloth and wipe each belt thoroughly cleaning it and then take a clean dry cloth and wipe each belt thoroughly drying them off. And then close your belts back up and you're ready to start production again. The next thing we'd like to talk about is the vacuum filters. The vacuum filters on I would say 85 to 90% of all machines, they utilize vacuum belts, that's the belts that you just saw with the holes in them. And this is called a vacuum assist system. This vacuum assist system works very well. But it also collects everything in the environment that is raining down from above. dusty products. Whatever you're running the delivery system above the machine is not 100% clean. So the product comes down onto the belts and it gets drawn into the vacuum filter. So this vacuum filter needs to be cleaned and or replaced every eight hours or every shift. So you should clean this thing and it's very simple just open up the door, open up the lid on the top of this vacuum filter system. Take the filter out and you can either blow it out with air if your plant allows you to do that. Or you can take it to a trash receptacle and just gently tap it on the side and everything will come out of it. Place it back in, snap the lid back in place and close up your doors. The next thing we're going to talk about is the film carriage on the backside of the machine. We'd need to have the operators clean each one of the rollers with a dry, clean rag. And while they're doing this, they're also going to notice whether or not the roller is worn back or stuck. If your rollers are stuck and frozen in place, then they're not turning and they're not allowing the film to move freely through the film carriage. And this will also make the belts out front work twice as hard. So, while the operators are wiping each one of these rollers down, they are also noticing these other defects in them. And it also keeps the product that rains down from above, off of the rollers and off of your film. Okay, so the next thing we're going to talk about is the power unwind belt. The power unwind belt is the drive unit, that drives, assists the roll in motion the roll of film, some of these roles of film get very heavy, and it takes quite a bit to get them in motion. So we put a power unwind back there to assist these film rolls to move. This belt needs to be cleaned just like the transport belts out front. They all three of these belts move the same amount of film and the build up and everything gets on this belt also. So this belt is slipping. It's making your belt out front work twice as hard. So we need to clean this belt again with a clean damp rag, wiping it down thoroughly. And then take a clean dry rag and dry it off thoroughly. Okay, so the next thing we're going to talk about is the air separator. This is kind of important. You have the regulator and the separator. And but you see the smaller device in the front that's where we do our lockout tagout for the air, but the one with the gauge on it. Below it has a canister with sight glasses on it so that you can see inside of it to see if there's water or oil or other contaminants. Just below that, on the bottom there is a thumb wheel or a thumb screw. You can loosen this thumb screw up and drain this thing into a bucket or some type of a receptacle and once it's drained and the bowl is empty. You see nothing in the sight glass and you just tighten the screw back up and you're ready to run again. So the next thing we're going to talk about is the monthly and our I'm sorry, the weekly and the monthly tasks that need to be done. Before we go into the weekly and monthly tasks, I just want to say something about the daily tasks. These are very important. If we do this 10 minutes at the beginning of every shift and your operators perform this correctly, this is going to keep you in production your entire shift. It's going to maximize your output, decrease your scrap rates. And it's also going to help with the longevity of spare parts, increasing the lifespan level. So the daily tasks, take care of 90% of all issues that arise during your shift with just doing this first 10 minutes of every shift. I just can't say enough about that. Okay, so the weekly tasks that we're going to be talking about are your forming collars and your forming tubes and changing out the Teflon tape. On the very center of your forming tube with your belts in the open position in your film moved out of the way, you're going to see on each side of your forming tube where the belts make contact with the film, there are two Teflon strips. We do have some customers out there that have special coatings on their forming colors and their tubes to where they don't use the Teflon strips. The Teflon tape on most tubes resides just underneath the transport belts. These need to be visually checked and probably changed for wears tears. If it's starting to roll, if the adhesive has come loose. product is built up on it or whatever, you can easily just strip this tape off and replace it. On your vertical seal area. You have two pieces there. One is the Teflon tape over top. And then underneath of your Teflon tape, you have a vertical seal strip, we need to check this vertical seal strip once a week to make sure that there are no waves or voids in it. No wear patterns on it. Anytime you have a wavy area, you're going to leave voids in your vertical seal. So this is going to decrease the integrity of that vertical seal. So we need to make sure that that strip is in good working condition. Also to make sure that your vertical seal bar is striking this strip squarely when it's engaged To your film to get a proper seal Once the strip has been inspected and or replaced, then you put your Teflon tape back over top of it and you can thread your tube back up. before you move on. We want you to check the alignment of the last roller on the three setup rollers. To the tube or the forming collar. You can see the three little smiley faces Well, there's only one smiley face and two frowny faces. The last set of rollers three rollers before the film enters into the forming collar. On the backside of your form and collar you have an angle and we want this last roller to be aligned to the point to where you're film lays perfectly flat on the angle of the rear of the forming collar. And you can see on the top one that the last roller is higher than the angle is and the film is not resting on it. This is going to create excessive wear on your forming collar. Because it's pulling on the film and putting undue stress on your film. You may even see little squiggly marks we call them stress marks on your bag. So you want to make sure that it is not riding above. On the second little frowny face. You can see that the film is breaking down to reach the last roller and that also creates excessive wear on the back edge of the collar. This thing will become razor sharp back there if you're if you run it like this for too long. The very bottom one, you see that the film is coming straight off of the angle, right to the last roller. And he's happy. Now with that, that puts equal amount of pressure on your wings of your collar. And it assists with your film tracking from side to side. If you've got this film broken down, the film's gonna want to track funny if you've got it lifted up and fell more track funny also, but it'll also put little lines on your bag, the stress marks that I was talking about. So for equal wear and good longevity of your forming collar, you will want to run it just like the third image on the bottom where the guy's smiling. Okay, the next thing that we're going to talk about is your lubrication. This happens every month. This is on the newer machines, the older machines we used oil to lubricate everything on the your drive systems, your transport systems, your transport belts, everything was oiled. And this was back in the old days, new or newer equipment requires grease. So on the old machines, you would see when you opened up your side door to do this lubrication, you would see actually a tank inside and that tank was filled with oil, and it had a handle on the side of it. And that requires three pumps for every eight hours of runtime to wear the new machines. We have the zerk fittings, and the zerk fittings go to each and every component that needs to be lubricated. The grease lasts much, much longer. So this is why you only do it every month and the oil bath system, you have to do it every eight hours of runtime. So this lubrication system is in the grease is much better. So if there are any questions about these zerk fittings and where they go, what they're lubricating, and the types of grease that you should be using, these can all all of these charts and information can be found in the back of your operator's manual. It gives you the frequency the types of oil, or I'm sorry, the types of grease that you could be using and it also gives you cross references on different types of grease, which they're all food great. If you can't find these, feel free to call us at any time and we can send them to you or two where to locate them? Whatever you need.

艾米丽·布罗根

这些都是关于手册的，对吧?

劳伦斯不

是的。是的,女士。好吧，你有完整的手册吗，或者我们可以把图表发给你。我们可以送你想要的任何东西。

艾米丽·布罗根

如果我准备的不对，请原谅。唐，你提到过，通常情况下，不是每次换班的时候都要加三个泵吗?

劳伦斯不

不，那是给油系统的。油系统里面有一个油箱，油箱上有一个黑色把手。每8小时，你必须抽三次油。但是在润滑系统上，我们的新系统上都有。天啊，我都不知道我们从哪年开始做这个的，但已经有一段时间了。润滑脂系统润滑脂持续的时间更长。好吧。好吧。因此，如果您需要任何有关机器中润滑脂MSDS表的帮助，请随时与我们联系，我们可以将其发送给您。好了，接下来，继续往这里走。 The next thing we're going to talk about are your safety switches. These are very important devices on your machine and they protect the operators and the people that use the machines and they also protect the equipment. Okay, anytime you open up or break the circuit on any of these circuit, these safety switches, it should act just like striking the emergency stop button. Okay, and these need to be inspected at least every month to make sure that they are functioning properly. This is a very important safety is huge. I know it isn't all of your plants. Most of your plants probably have your own safety guidelines, when to test and when they need to test or replace. So it's very important to keep these safety devices operational. Okay, we just can't stress that one enough. Okay, the next thing we're going to talk about is the cabinet housing filter. This is the same door that you opened up to do your lubrications and it's also where all of the moving parts of the machine are for your film, drive your jaw drive, all of your servo motors, gearboxes, bushings, bearing, shafts, everything are inside of this cabinet. Okay, this cabinet door has a filter in it because we have a lot of heat generating devices inside of the machine. So the inside and all of these devices they need to breathe. Now, these doors are sealed to keep all of the external contaminants from getting inside. So we need to make sure that this filter is clean so that we can get clean, fresh air inside this cabinet with no contaminants from the outside. So once a month, we ask that you open this door up, remove this air filter, clean it and or replace it. Okay? Again, this is just like the other filter it can be blown off or it can just be dusted into a trash receptacle. Okay, next thing we're going to move to is how your daily tasks are completed. These daily casts once again, we just can't convey to you You guys how important these, this first 10 minutes of the shift can make such a difference on all of your, you know, all of the things that Shahram talked about the longevity, the downtime, spare parts, savings and all of this, you can see how this all kind of comes together. And these daily practices are basically on your operators. A clean machine is a happy machine, and a happy machine is a productive machine. So, keeping all of these daily tasks up to date every day. You can see where this can be just a huge cost savings to you and to your customers.

Shahram Shariff

而且没有压力!

劳伦斯不

无压力,是的。

艾米丽·布罗根

一个干净的机器是快乐的机器。唐，如果你每对一个人这么说一次你就有1美元，你会有多少美元?

劳伦斯不

我会成为一个有钱人。这也是千真万确的。这句话我已经说了很多年了，你怎么说都不够。我走进一家工厂，你会看到一台完全覆盖的机器。这些就是你可能会遇到问题的机器。当你进入一个工厂，机器只是，它看起来。它已经10年了，但看起来已经10天了。这些机器将永远存在。这是真的。

艾米丽·布罗根

谢谢你这么详细地介绍我们如何正确地执行这些任务。在我们把这些问题删掉之前，有些人已经把一些很棒的问题发送到聊天的问答部分了。在我们开始之前，我想测试一下每个人的倾听程度。如果你不介意，请打开你的聊天功能。我给大家几秒钟时间把它拉上来。前五名在这个问题上100%答对的人将获得奖励，奖励是一个RTIC的绝缘旅行杯。我不知道是不是每个人都熟悉这个品牌。所以我在拖延时间，以确保每个人都能把车拉上来。这是我们的问题。那么，我们所涵盖的实现停机、避免和密封完整性等结果的两个基础是什么?

劳伦斯不

我很抱歉,

艾米丽·布罗根

这是快!

艾米丽·布罗根

我想我们所有的赢家都有了。所以我们不会错过任何它不会浪费更多的时间。我们将继续向你们开放，让Shahram和Don回答其中一些问题，欢迎你们将它们添加到聊天或使用问答功能。我想说的是，如果你匿名发送给我们，我们没有时间，我知道我们已经超出了计划的时间。如果你匿名回答如果你给我们一个问题然后我们不一定能知道谁发送一个响应后,因为我们要去尝试把这些后我们打电话回到你在个人的基础上。我来问你一个问题。这里有一个好例子。没有特氟隆棒的清洁，你推荐的硬度是多少?

Shahram Shariff

如果您使用唐暗示并且正如我们推荐的那样使用黄铜刷，那么它的刚度不会发挥作用，因为您有材料是重要的材料。

艾米丽·布罗根

所以它的硬度没有材料的高。

Shahram Shariff

对吧?

艾米丽·布罗根

好吧。很高兴知道。

劳伦斯不

我指的是硬的和软的，因为这就是它们在你手里的感觉，但知道确切的我不知道。

Shahram Shariff

对,是的。但正如你说的，唐，我们不想用这把钢刷把它们刮掉。钢刷要硬得多但绝对是硬得多。而黄铜是软的。

艾米丽·布罗根

是的。

劳伦斯不

是的。你知道，钢的钢在其上有更多的多孔表面，这往往划伤而不是实际刷。正确的。

艾米丽·布罗根

我还有一个关于刷子的问题我有:“黄铜刷子会产生安全问题吗?

劳伦斯不

不。不比任何人多。

艾米丽·布罗根

好吧。

Shahram Shariff

不。再次,我想回去也和我谈过,如果这样做是在日常和一致的基础上,那么你就不会有这些代谢产物在垂直密封或你的下巴关心真正进入他们和挖出来。如果你已经。如果你已经处于这种情况下，那可能会在密封面上形成蛋糕你甚至无法用油灰刀去除它们。

艾米丽·布罗根

是的。

劳伦斯不

是的。

艾米丽·布罗根

这是另一个问题。你建议用哪种产品清洗运输带和放卷带?

劳伦斯不

哪个产品?

Shahram Shariff

是的，我认为我认为我们的建议是用湿的，也就是说用清水，干净的水就是干净的水，湿的，干净的，湿的布就可以了。

艾米丽·布罗根

好吧。

Shahram Shariff

所以你要用的化学物质是水

艾米丽·布罗根

水!好了，我还有一个。皮带打滑的常见问题是什么?

劳伦斯不

最常见的问题是皮带打滑就像我一开始说的，皮带很脏，很滑。真空辅助罐被装满或堵塞。此外，如果您的膜架上的滚轮不能自由转动，如果动力放松皮带脏和打滑。现在，还有一些其他的问题可能是造成这种情况的原因那就是你的皮带没有正确地与管子对齐你必须有良好的接触顶部和底部，所以皮带必须与管子平行。这样你就有了一个完整的接触面。如果一边拉得比另一边更用力，或者你知道你的胶片跟踪失灵了，就会产生各种各样的问题。因此，保持皮带清洁，保持您的膜架滚轮自由转动，并保持您的trans或您的电力放松皮带清洁。

艾米丽·布罗根

唐酒精会损坏皮带吗?

劳伦斯不

不，只要它是一种变性酒精你可以把它用在你的皮带上。变性酒精的效果非常好。但在大多数工厂，这是不允许的。所以我们不建议你使用它。但它确实运行得很好。让皮带又回到了俗气的状态。只要你使用变性酒精，不带护手霜或任何会导致皮带表面打滑的东西。

艾米丽·布罗根

好吧。唐，这正合你意。我应该多久更换一次vpk的轴承。我知道你对那些老型号很熟悉。

劳伦斯不

是的。和vpk。它们是非常好的机器，如果你正在使用OEM产品，这意味着你从我们这里购买轴承，我们放在机器里的轴承，你知道，只要你购买那个质量或那个等级的轴承，你应该至少有一年的时间可以使用你的曲柄臂轴承。这些是最常见的轴承，因为它们很难。有些人很难把事情弄清楚。这些轴承不是制造有一个侧面负载或任何东西。但如果你把它们放在那里，把它们弄得很直，它们应该至少能维持你一年。所以我希望每年都能更换这些轴承。这里也有很多变量。你知道吗?有多少年纪更大的…

Shahram Shariff

你是全天候运行吗?

劳伦斯不

完全正确。变数是，如果你是三班倒，一天24小时，一周7天，一年365天。你可能得不到完整的一年。而且，如果你的秤设置不正确，你知道，这些旧的机器，如果你每分钟运行120袋，这些旧的机器，开始时是每分钟120袋，停止时是每分钟120袋。所以如果你的秤喂得不合适或者运转不正常，然后机器启动，运行15个袋子，然后停止，然后它开始…等待两个周期，开始运行，再次运行15-20袋，然后停止。启动和停止的条件对你的轴承是非常困难的。所以我只能指望一年了。

艾米丽·布罗根

好吧。谢谢你们的提问。我们已经超出时间限制了。如果你花时间提交一个问题,我只是想让你知道这不是再次消失在虚空,如果是匿名寄给我们,你觉得不舒服的话重新提交你的名字,我们有,我认为,在200年和不同的东西在我们的文章我们网站上的知识库讨论了你的系统可能抛出的各种代码。所以你可以在那里做一些研究。我们实际上要开另一个会议来解决这些问题我们会在个人的基础上给你们答复。这些,如果我们需要我们的服务和支持团队,我们将分报告,如果有任何一个具体的事情,你们和女孩带你今天就是你每天真的是你的第一道防御计划外停机,产品损失,部分失败,你的mvp,正如Shahram提到的,都是每天操作这些机器的人。这些是核心的基本原则和最佳实践。以我们的经验和我们与客户的成功，我想感谢沙赫拉姆和唐今天加入我们并传授你们几十年来在装袋上的智慧。我想亲自感谢各位，我们的与会者收听今天的网络研讨会。希望大家喜欢，下节课再见。再见,每个人!

劳伦斯不

我希望这些都能帮助到男人。祝你玩得愉快!
