柴油发电机组的维护方法

发布日期: 2018-09-04 来源: / 点击:

目前柴油发电机组仅限于以下维护手段:对发电机组的四漏现象、表面、启动电池、机油和燃油等的检查;清洁改善机房环境,定期更换三滤;每月进行空载,每半年进行加载试机等方面维护;使用电源**进行实时观测电质量参数。自动变速箱维修厂家小编接下来为您详细先容一下柴油发电机组的维护方法

At present, the diesel generator set is limited to the following maintenance means: checking the four leakage phenomena, surface, startup battery, engine oil and fuel oil of the generator set; cleaning and improving the environment of the engine room, changing the three filters regularly; carrying out no-load monthly, loading and testing every six months; real-time observing the power quality parameters using the power supply** Number. Automatic gearbox maintenance manufacturer Xiaobian, next, I will give you a detailed description of how to maintain the diesel generator set.
现有维护手段局限性:现有维护中的加载测试也只是对后端现有用电设备的带载测试,存在一定风险,并且功率较低;更换三滤或经过大修没有科学依据;更换三滤或经过大修后,没有专门负载进行加载试机,不清楚是否能达到预期目的;空载试机和小功率带载产生的大量积碳。
Limitations of existing maintenance methods: Loading test in existing maintenance is only on-load test of the existing back-end electrical equipment, there is a certain risk, and low power; replacement of three filters or overhaul without scientific basis; replacement of three filters or after overhaul, there is no special load loading test machine, it is not clear whether it can be achieved. To the expected purpose; large amount of carbon generated by no-load test and low power load.

柴油发电机组在小负荷下运行,随着运行时间的延续,会出现以下故障:
Diesel generators operate at low loads. With the extension of the running time, the following faults will occur:
1、对于增压式柴机组,由于低载、空载,增压压力低,容易导致增压器油封(非接触式)的密封效果下降。
1. For turbocharged diesel units, the sealing effect of the oil seal (non-contact type) of the turbocharger will be decreased because of low load, no load and low pressure.
2、增压器的增压室内机油积聚到一定程度,就会从增压器的结合面处渗漏出。
2. The oil accumulated in the supercharger chamber will leak out from the supercharger joint.
3、上窜至汽缸的一部分机油参与燃烧,一部分机油不能完全燃烧,在气门、进气道、活塞顶、活塞环等处形成积炭,还有一部分则随排气排出。这样,汽缸套排气道内就会逐步积聚机油,也会形成积炭。
3. A part of the oil flowing up to the cylinder participates in the combustion, and a part of the oil can not be completely burned. Carbon deposits are formed at the valve, intake port, piston top, piston ring, etc., and some are discharged with the exhaust. In this way, the cylinder will gradually accumulate oil in the exhaust passage and form carbon deposits.
4、长期小负荷运行,还会更严重的导致运动部件磨损加剧,发动机燃烧环境恶化等导致大修期提前的后果。
4. Long-term operation under small load will lead to worse wear of moving parts, worsening combustion environment and other consequences of overhaul ahead of schedule.
因此自动变速箱维修厂家在机器出厂前无论对自然吸气型还是增压机型的使用都强调应尽量减少低载/空载运行时间,并规定较小负荷不能低于机组额定功率的25%—30%。
Therefore, the automatic transmission maintenance manufacturer emphasizes that the operating time of low load/no load should be reduced as far as possible, and the minimum load should not be lower than 25%-30% of the rated power of the unit.
