如果问大家,究竟是事后维修好还是预防维修好?可能大多数人认为预防维修好。那么,与事后维修比较,到底预防维修好在哪里,似乎很少有人认真去思考。
If we ask you, is it after repair or preventive maintenance? Most people think that preventive maintenance is good. So, compared with the maintenance after the accident, it seems that few people seriously consider where the preventive maintenance is good.
 
预防维修有两种具体模式,一是定期预防维修,就是按照压缩机设备耗损周期计划安排的停机检修;二是状态维修,就是对设备状态进行监测,发现故障隐患或者潜在故障,及时安排适时维修,将故障消灭在萌芽状态。
Preventive maintenance has two specific modes, one is regular preventive maintenance, that is, according to the compressor equipment wear cycle schedule of downtime maintenance; the other is condition maintenance, is to monitor the status of equipment, find hidden troubles or potential failures, timely arrangements for timely maintenance, the failure will be eliminated in the bud state.

预防维修的另外一种形式是机会维修。即利用生产的淡季、假日、周末或者上下游停机检修的机会进行的预防性维修。机会维修的“机会”可以是适当延长检修周期,也可以是适当的将检修周期缩短,经过论证,这种延长或者缩短是不会对设备造成重大损坏的。这样的预防维修也称为机会维修。无论是采取何种预防维修方式,都是在设备故障停机前的处理,目的是避免故障的发生。
Another form of preventive maintenance is opportunistic maintenance. That is to use the production off-season, holidays, weekends or downstream downstream maintenance opportunities for preventive maintenance. Opportunity maintenance "opportunity" can be appropriate to extend the maintenance cycle, or it can be appropriate to shorten the maintenance cycle, after verification, this extension or shortening will not cause significant damage to the equipment. Such preventive maintenance is also known as opportunistic maintenance. No matter what preventive maintenance methods are adopted, they are all dealt with before the equipment breakdown, and the purpose is to avoid the breakdown.
到底预防维修好在哪里呢?我们具体来探讨一下:
What is the best place to prevent maintenance? Let's talk about it in detail.
 
1.可以减少和避免非计划停机
1. can reduce and avoid unplanned downtime.
 
当今企业多数按照订单来组织生产,客户对交货期的要求十分严格,在精益生产企业,准时化、零库存成为典型特征。压缩机作为非常重要的一种动力源,一旦因为设备停机,就必然会影响某一生产工序,这个订单就会受到影响,这对企业效益、信誉都会有很大伤害。通过预防性维修,避免大量非计划停机,保证准时交货,其意义重大。
Nowadays, most enterprises organize production according to orders. Customers have strict requirements on delivery time. In lean production enterprises, punctuality and zero inventory become typical characteristics.  Compressor as a very important power source, once the equipment is shut down, it will inevitably affect a certain production process, the order will be affected, which will be a great harm to the efficiency and credibility of enterprises. It is of great significance to avoid large numbers of unplanned downtime and ensure punctual delivery through preventive maintenance.
 
2.可以减少设备的连锁损坏,延长设备寿命
2., it can reduce the chain damage of equipment and extend the life of equipment.
 
设备损坏往往是从局部或某个零件开始,这个局部或者零件又影响了其它局部或者零件,一步一步传递,最后酿成大问题。由于压缩机常常作为动力源,因此,压缩机的某个部件的质变、损坏不仅仅会造成压缩空气系统的故障,而且还会通过压缩空气管道,传递到压缩空气应用环节的设备上去,比如空滤损坏造成压缩空气喷嘴、压力表腐蚀等,这是系统的多米诺骨牌现象。预防性维修可以减少或者避免轻微损坏,或者将小隐患及时消除,避免影响扩大,最后导致更严重的故障损坏。
Equipment damage often starts from a part or a part, which affects other parts or parts, step by step, and eventually leads to major problems. Because compressors are often used as power sources, the qualitative change and damage of a part of the compressor will not only cause the failure of the compressed air system, but also pass through the compressed air pipeline to the compressed air application equipment, such as air filter damage caused by compressed air nozzle, pressure gauge corrosion, etc. It is a systematic Domino phenomenon. Preventive maintenance can reduce or avoid minor damage, or eliminate minor hidden dangers in time to avoid the impact of expansion, and ultimately lead to more serious failure damage.
 
3.可以降低维修成本
3., reduce maintenance costs.
 
当然,不当的“预防维修”不但不会降低成本,还会增加成本,我们称之为维修冗余或者维修过剩。我们这里是指恰当的预防维修可以降低维修成本。一般而言,有计划的工作其效率是无计划工作效率的3倍到4倍。预防性维修因为其计划性,可以事先研究修理方案,准备好图纸、工具、吊具等辅助设施材料,准备好备件。一旦解体维修,可以高效完成维修工作。反之,如果是事后维修,人们在突然停机的匆忙之中诊断原因,再寻找工具、备件、材料,真正的维修需要半天,而前期的准备可能会是一天半到两天,时间效率的降低明显,维修成本自然增加,加上事后维修可能造成的连锁损坏,换件损失也会增加,更加大了维修成本。
Of course, improper "preventive maintenance" will not only reduce costs, but also increase costs, which we call maintenance redundancy or overmaintenance. We mean that proper preventive maintenance can reduce maintenance costs. Generally speaking, the efficiency of planned work is 3 times to 4 times that of unplanned work. Preventive maintenance because of its planning, you can study the repair plan in advance, ready drawings, tools, hangers and other auxiliary facilities materials, ready for spare parts. Once disassembled and maintained, the maintenance work can be completed efficiently. On the contrary, if it is maintenance after the accident, people diagnose the cause in the rush of sudden shutdown, and then look for tools, spare parts, materials, the real maintenance needs half a day, and the preparation may be a day and a half to two days, the time efficiency is reduced significantly, the maintenance cost increases naturally, plus the maintenance after the accident may cause chain. Damage, loss of replacement will also increase, greater maintenance costs.
 
但是,也有的不规范代理商,利用自己的地位优势,故意提高了“预防维修”频次,加重了用户的维修成本负担。
However, some non-standard agents, using their position advantages, deliberately increased the frequency of "preventive maintenance" and increased the maintenance cost burden of users.
 
4.可以降低安全事故风险
4., we can reduce the risk of safety accidents.
 
预防维修可以将设备局部的、轻微的或者初发的缺陷加以消除,这样可以单独降低安全事故发生的风险。有些压缩机严重故障本可以避免,但是由于没有预防维修的机会,导致故障危险程度越积越高,最终酿成比较大的后果。轻则机头抱死、轴承弯曲,重则机毁人亡。
Preventive maintenance can eliminate local, minor or initial defects of equipment, which can reduce the risk of safety accidents alone. Severe faults of some compressors could have been avoided, but because there is no chance of preventive maintenance, resulting in a higher degree of failure risk, eventually leading to greater consequences. While the machine is locked, the bearing is bent and the machine is destroyed.
 
5.可以避免和降低批量的质量缺陷或者报废
5., we can avoid and reduce batch quality defects or scrap.
 
很多设备在故障的过程中,会造成大量的质量缺陷或者报废。压缩机排气含油量不合格,就会造成食品、电子产品报废;排气压力不稳定,就会造成纺织品报废,尽管可以通过储气罐等后处理设备来消除,但是总的来说增加了用户的生产成本和风险……,这样的例子很多。因此,预防性维修可以从某种程度上减少或者避免故障期间的批量质量劣化或者报废,减少因为故障——报废造成的经济损失。
Many equipment will cause a lot of quality defects or scrap in the process of failure. Compressor exhaust oil content is not up to standard, it will cause food, electronic products scrap; exhaust pressure instability, it will cause textile scrap, although can be eliminated by gas storage tanks and other post-processing equipment, but in general increased the cost of production and risk of users... There are many such examples. Therefore, preventive maintenance can reduce or avoid mass quality deterioration or scrap during failure to some extent, and reduce the economic losses caused by failure-scrap.
6.可以使得工作更主动,更有计划性和预见性
6., it can make the work more proactive, more planned and predictable.
 
预防维修中的机会维修可以使得工厂的生产计划、工作时间安排和资源配置更加合理,更加有计划,也就更加主动。有的工厂实施的夜班检修、周末检修、月末检修,就是利用生产任务完成的间隙所进行的机会检修。很多钢厂实施的同步检修也是利用上下游停机间隙所进行的机会维修;饮料、冰箱、冷柜、空调生产企业夏天生产任务紧,冬天较为清淡,可以将预防维修尽量安排在冬天;卷烟行业冬天任务紧,夏天稍微轻松,可以将机会检修安排在盛夏。当企业维修任务紧时,可以适当调节维修间隙,以便有效的利用维修人力和设施资源。总之,机会性的预防维修可以让工作的计划更灵活。
Opportunity maintenance in preventive maintenance can make the production plan, work schedule and resource allocation more reasonable, more planned and more active. Some factories carry out night shift maintenance, weekend maintenance, month-end maintenance, is to use the gap between the completion of production tasks to carry out opportunity maintenance. Many steel plants implement synchronous maintenance is also the use of upstream and downstream shutdown clearance opportunities for maintenance; beverage, refrigerators, refrigerators, air conditioning production enterprises summer production tasks tight, winter is light, can be preventive maintenance as far as possible in winter; cigarette industry in winter task tight, summer a little easier, you can have the opportunity to check The arrangement is in midsummer. When the maintenance task is tight, the maintenance gap can be adjusted appropriately in order to effectively utilize the maintenance manpower and facilities resources. In short, opportunistic preventive maintenance can make work plans more flexible.
 
7.降低环境破坏的风险
7. reduce the risk of environmental damage.
 
与降低安全伤害一样,预防性维修可以有效的降低环境破坏风险。设备,尤其是牵涉到有毒气体,液体得设备泄漏会造成环境破坏;设备的噪音也会污染环境。企业内部的水处理、空气净化设备直接关系到对排放环境的影响。
Like reducing safety hazards, preventive maintenance can effectively reduce the risk of environmental damage. Equipment, especially those involving toxic gases, leaks from liquid equipment can cause environmental damage; noise from equipment can also pollute the environment. The internal water treatment and air purification equipment is directly related to the emission environment.
 
8.有利于节能降耗
8. is conducive to energy conservation and consumption reduction.
 
设备不良运行,往往会增加摩擦和能耗。预防性维修可以保证设备、设施的流畅平稳运行,可以有效降低能耗,维持设备的节能效果。
Poor equipment often increases friction and energy consumption. Preventive maintenance can ensure the smooth and smooth operation of equipment and facilities, can effectively reduce energy consumption and maintain the energy-saving effect of equipment.
 
有的用户采购的高效节能设备,但是运行一两年之后却反应设备不节能,其实,不合理保养维修是很重要的一个因素。毕竟,压缩机作为一个耗能大户,不但要会买更要会用,这样才能真正达到节能降耗的目的。
Some users purchase efficient energy-saving equipment, but after one or two years of operation, the reaction equipment is not energy-saving, in fact, unreasonable maintenance is a very important factor. After all, compressor as a large energy-consuming household, not only to buy more to use, so as to truly achieve the purpose of energy saving.
