Engine oil plays a series of important roles in diesel generator set, such as lubrication, cooling, cleaning and sealing. It ensures the normal operation of diesel generator set, reduces the failure rate of diesel generator set, improves the performance, and effectively extends the service life of diesel generator set

在使用柴油發(fā)電機組的過程中一定要及時檢查機油的使用情況，及時的更換新機油，確保柴油發(fā)電機組的正常運轉(zhuǎn)。但對于很多不熟悉柴油發(fā)電機組的用戶來說，何時換新機油，如何更換機油面臨很大的挑戰(zhàn)，下面為大家詳細說明一下柴油發(fā)電機組更換新機油要點。

In the process of using the diesel generator set, we must check the use of the engine oil in time, and change the new engine oil in time to ensure the normal operation of the diesel generator set. However, for many users who are not familiar with the diesel generator set, when and how to change the engine oil are facing great challenges. The following is a detailed description of the main points of replacing the diesel generator set with new engine oil.

正常情況下全新的柴油發(fā)電機組在次運行50個小時后需要更換一次新機油，這個期間主要是機器的磨合期，在更換新機油的時候不要忘記更換機油濾清器，機油濾清器要和機油一并更換，柴油發(fā)電機組日常運作中運作時間滿250小時就建議更換一次新機油，不要超過300小時，如果柴油發(fā)電機不是每天都很頻繁的運作，也可以一個月更換一次，機油的更換時間和機油的種類品質(zhì)也有關(guān)聯(lián)，加入好的機油可以運作400個小時后再更換.

Under normal circumstances, the new diesel generator set needs to be replaced with new engine oil after the first 50 hours of operation. This period is mainly the running in period of the machine. When replacing the new engine oil, don't forget to replace the engine oil filter. The engine oil filter should be replaced together with the engine oil. It is recommended to replace the new engine oil after 250 hours of daily operation of the diesel generator set If the diesel generator does not operate very frequently every day for more than 300 hours, it can be changed once a month. The oil change time is also related to the type and quality of the oil. With good oil, it can be changed after 400 hours of operation

柴油發(fā)電機組換機油分為正常情況和非正常情況：

The oil change of diesel generator set is divided into normal condition and abnormal condition

非正常情況指的就是柴油發(fā)電機組因故障維修過后以及長時間不使用的時候，柴油發(fā)電機組因較大故障維修過后運行50個小時之后也要更換新機油，還有就是長時間不使用柴油發(fā)電機組.

Abnormal situation refers to the diesel generator set due to fault maintenance and long time not in use, diesel generator set due to major fault maintenance after 50 hours of operation also need to change the new oil, there is a long time not to use the diesel generator set

在使用前也要檢測機油各項指標是否正常，可以用將新機油和使用中的機油滴在白色的試紙上來比較，如果使用中的機油變成了黑褐色就要及時更換，還有就是檢測使用中的機油的粘度，將新機油和使用中的機油放在兩根相同的玻璃管中，密封好以后同時倒置，記錄氣泡的上升時間，如果兩者氣泡上升時間相差超過百分之二十就說明機油粘度下降過多，應(yīng)該更換使用中的機油

Before use, we should also check whether the indicators of the engine oil are normal. We can compare the new engine oil with the engine oil in use by dropping it on a white test paper. If the engine oil in use turns black brown, we should change it in time. In addition, we should check the viscosity of the engine oil in use. Put the new engine oil and the engine oil in use in two identical glass tubes, seal them well, and then turn them upside down at the same time Record the rising time of air bubbles. If the difference between the rising time of air bubbles is more than 20%, it means that the viscosity of the engine oil drops too much. The engine oil in use should be replaced
