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.

現有維護手段局限性：現有維護中的加載測試也只是對后端現有用電設備的帶載測試，存在一定風險，并且功率較低；更換三濾或經過大修沒有科學依據；更換三濾或經過大修后，沒有專門負載進行加載試機，不清楚是否能達到預期目的；空載試機和小功率帶載產生的大量積碳。

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.

柴油發電機組在小負荷下運行，隨著運行時間的延續，會出現以下故障：

Diesel generators operate at low loads. With the extension of the running time, the following faults will occur:

1、對于增壓式柴機組，由于低載、空載，增壓壓力低，容易導致增壓器油封（非接觸式）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、增壓器的增壓室內機油積聚到一定程度，就會從增壓器的結合面處滲漏出。

2. The oil accumulated in the supercharger chamber will leak out from the supercharger joint.

3、上竄至汽缸的一部分機油參與燃燒，一部分機油不能完全燃燒，在氣門、進氣道、活塞頂、活塞環等處形成積炭，還有一部分則隨排氣排出。這樣，汽缸套排氣道內就會逐步積聚機油，也會形成積炭。

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、長期小負荷運行，還會更嚴重的導致運動部件磨損加劇，發動機燃燒環境惡化等導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.

因此自動變速箱維修廠家在機器出廠前無論對自然吸氣型還是增壓機型的使用都強調應盡量減少低載/空載運行時間，并規定較小負荷不能低于機組額定功率的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.
