当前很多燃气内燃机的技术也依然受制于国外厂家，一旦出现大故障必须返厂维修，这大大影响了能源站的正常供能，同时也将维修成本提高了一个档次。看来国产机组不出头，布局再多的分布式内燃机，也只是给自己多埋了坑。再次感悟科学技术才是第一生产力，真理就是真理。

　　Currently, the technology of many gas internal combustion engines is still limited by foreign manufacturers. Once a major malfunction occurs, they must be returned to the factory for maintenance, which greatly affects the normal energy supply of the energy station and also increases the maintenance cost by one level. It seems that domestic units are not making a name for themselves, and no matter how many distributed internal combustion engines are deployed, they are only digging more holes for themselves. Once again, realize that science and technology are the primary productive forces, and truth is truth.

　　燃气91看片神器下载，尤其是分布式项目中能够接触到的机型，全部是按照连续运行设计的，具备24*365运行的能力。机组长期运行中，维护和保养会极大的影响机组的性能。

　　Gas generator sets, especially the models that can be accessed in distributed projects, are all designed for continuous operation and have the ability to operate 24 * 365. During long-term operation of the unit, maintenance and upkeep will greatly affect its performance.

　　小编今天来说一说燃气机组运维保养方面的基础知识，由于不准备细化到具体机型，因此本文中所涉及到的数据，都是概念性的，相关的项目也只是常规性概念，准确的项目和数据必须以相关机型的保养手册为准。

　　Today, the editor will talk about the basic knowledge of gas turbine operation and maintenance. As we do not intend to delve into specific models, the data involved in this article are conceptual, and the related projects are only routine concepts. Accurate projects and data must be based on the maintenance manual of the relevant type.

　　维护保养的类型：

　　Types of maintenance and upkeep:

　　内燃机的保养，大体上可分为两个大类：周期性的、和运行小时数无关的。和运行小时数无关的保养包括更换机油、更换各类滤芯；周期性保养包括日常检查、常规维保、小修、中修、大修、涡轮增压器检修。

　　The maintenance of internal combustion engines can generally be divided into two categories: periodic and independent of operating hours. Maintenance unrelated to operating hours includes changing engine oil and replacing various filter elements; Periodic maintenance includes daily inspections, routine maintenance, minor repairs, medium repairs, major repairs, and turbocharger maintenance.

　　日常检查对设备的巡检，围绕设备进行目测检查，看是否有跑冒滴漏和异常现象，检查液位、油位，记录设备运行参数。日常检查的频率根据能源站/电厂的制度自定，较为严格的电厂要求每小时巡检。

　　Daily inspection of equipment, visual inspection around the equipment to see if there is any leakage or abnormal phenomenon, checking the liquid level and oil level, and recording the operating parameters of the equipment. The frequency of daily inspections is determined according to the regulations of the energy station/power plant, and stricter power plants require hourly inspections.

　　常规保养常规保养通常指的是大家最为熟悉的“换火花塞”级别的保养。其内容通常包括更换火花塞、检查/调整气门相关各项参数、发电机加润滑脂等。

　　Routine maintenance usually refers to the most familiar level of maintenance, such as replacing spark plugs. The content usually includes replacing spark plugs, checking/adjusting various parameters related to valves, and adding lubricating grease to the generator.

　　各机型的常规保养时间间隔相差较大，有的小机组要求每两三百小时就要做保养，而一些机型则可以间隔4000小时以上。

　　The regular maintenance intervals vary greatly among different models. Some small units require maintenance every two to three hundred hours, while some models can have intervals of more than 4000 hours.

　　为了提高工作效率，降低停机时间，一些和运行小时数无关的保养项目，如换机油，常常会和常规保养放在同一时间做。

　　In order to improve work efficiency and reduce downtime, some maintenance items unrelated to operating hours, such as oil changes, are often performed at the same time as routine maintenance.

　　小修：小修通常也叫顶修，维修的范围主要是缸盖，小修时缸盖会被拆下，分解开来检查，通常会更换其中一部分零件，但没发现严重问题的话不会整体更换。

　　Minor repair: Minor repair is usually called top repair, and the scope of repair is mainly the cylinder head. During minor repair, the cylinder head will be removed and disassembled for inspection. Usually, some parts will be replaced, but if no serious problems are found, it will not be replaced as a whole.

　　中修：中修通常会采用所有气缸全部整体更换缸盖的方式进行，同时会对缸套、活塞、连杆、轴瓦等都进行检查（），如有必要进行更换。

　　Intermediate maintenance: Intermediate maintenance usually involves replacing the cylinder head of all cylinders as a whole, and inspecting the cylinder liner, piston, connecting rod, bearing shell, etc. If necessary, replacement will be carried out.

　　大修：大修在中修的范围上进一步扩大，包括曲轴、凸轮轴在内的几乎整个发动机都需要进行检查，大范围更换零件。现场通常不具备大修的工具和条件，需要将发动机返回原厂，工期至少在一个月以上（不含往返运输时间）。

　　Major overhaul: Major overhaul further expands the scope of medium overhaul, including almost the entire engine, including the crankshaft and camshaft, requiring inspection and extensive replacement of parts. The site usually does not have the tools and conditions for major repairs, and the engine needs to be returned to the original factory with a construction period of at least one month (excluding round-trip transportation time).

　　虽然各个厂家都给出了大修的时间间隔，但严格的来说，这只是个参考时间，大修也应该属于和运行时间无关的项目。是否需要做大修，需要很多指标综合来确认，比如最典型的两项：机油消耗量的增加；曲轴箱窜气量的增加由于大修工序复杂，时间长，对项目运营的影响非常大，所以各家主机厂现在都推出了一种替换的大修方案，称为长缸体置换。

　　Although each manufacturer has provided a time interval for major repairs, strictly speaking, this is only a reference time, and major repairs should also be considered as projects unrelated to operating time. Whether a major overhaul is needed requires a comprehensive analysis of many indicators, such as the most typical two: an increase in oil consumption; The increase in crankcase blow by volume has a significant impact on project operation due to the complex and lengthy overhaul process. Therefore, various major engine manufacturers have now introduced a replacement overhaul plan called long cylinder block replacement.

　　长缸体置换长缸体，实际上是一台接近完整的发动机，但不包括泵、阀、控制系统及一些非关键部件如进排气管道等，在现场可将长缸体和旧机对应的部分进行整体置换。有资质的维修人员在现场即可完成长缸体置换，时间约7-10天左右。

　　Replacing a long cylinder body with a long cylinder body is actually a nearly complete engine, but does not include pumps, valves, control systems, and some non critical components such as intake and exhaust pipes. On site, the corresponding parts of the long cylinder body and the old engine can be replaced as a whole. Qualified maintenance personnel can complete the replacement of the long cylinder body on site, which takes about 7-10 days.
