柴油發電機組增壓器的使用壽命

  為了保證柴油發電機組壓器的使用壽命,在設計上要保證對增壓器浮動軸承的潤滑和冷卻,同時,在使用中要求做到:

  In order to guarantee the service life of the turbocharger of diesel generator set, the lubrication and cooling of the floating bearing of the supercharger should be guaranteed:

  1、柴油發電機組起動后應怠速運轉3-5分鐘,不要立即加負荷,以保證增壓器的良好潤滑。主要原因是增壓器位于發動機的頂部,如果發動機起動后增壓器立即開始高速運轉,就會導致機油壓力未能及時升高給增壓器供油,造成增壓器缺油損壞,甚至燒壞整個增壓器。

D88尊龙  1, diesel generator set should be idle after starting 3-5 minutes, do not immediately increase the load, to ensure good lubrication turbocharger. The main reason is that the top of the turbocharger in the engine, if the engine starting after the turbocharger immediately began running in high speed, will cause the oil pressure failed to rise to the booster oil, causing the turbocharger oil damage, and even burn the entire supercharger.

  2、怠速時間不宜過長,一般不超過10分鐘,怠速時間過長容易造成壓氣機端漏油。

  2, idle time should not be too long, generally no more than 10 minutes, idle time is too easy to cause compressor end oil leakage.

D88尊龙  3、停車前不要立即關閉柴油發電機組,應怠速3-5分鐘,以使增壓器轉速和排氣系統的溫度降下來,防止發生回熱—機油結焦—軸承燒損等故障。溫馨提示:經常的不正確使用會使增壓器損壞。

D88尊龙  3, do not shut down immediately before stopping the diesel generator, should be idle for 3-5 minutes, the supercharger speed and exhaust system temperature down, to prevent the occurrence of heat recovery coking of oil - bearing - burning fault. Warm tip: often incorrect use will make supercharger damage.

  4、長期未使用的發動機或新換增壓器的柴油發電機組,在使用前應在增壓器的進油口加注機油,否則會因潤滑不良降低壽命或損壞增壓器。

D88尊龙  4, long-term unused engine or new supercharger diesel generator set, before use should be in the supercharger inlet oil filling oil, or because of lubrication bad life or damage supercharger.

  5、定期檢查各連接部位是否有松動漏氣或者漏油現象,回油管是否通暢,如有應及時排除。

D88尊龙  5, regular inspection of the connection site whether there is loose leakage or oil leakage phenomenon, whether the oil pipeline patency, if it should be promptly ruled out.

  6、保證空氣濾清器清潔,并按要求定期更換,定期更換機油濾清器。

D88尊龙  6, to ensure that the air cleaner clean, and according to the requirements of regular replacement, regularly replace the oil filter.

  7、定期檢查柴油發電機組增壓器軸的徑向軸向間隙,軸向間隙應不大于0.15毫米,徑向間隙為:葉輪與壓殼的間隙不小于0.10毫米,否則應請人員維修,以免擴大損失發電機。

  The radial axial clearance 7, regular inspection of diesel generator turbocharger shaft, the axial clearance should be less than 0.15 mm, radial clearance: the clearance between impeller and casing pressure of not less than 0.10 mm, or should be invited to professional maintenance, in order to avoid the expansion of the loss of the generator.
