  柴油發電機組低負荷運行的危害

D88尊龙  若機組在低負荷下運行,隨著運行時間的延續,會出現以下故障:

  If the unit under low load operation, as a continuation of the running time, can appear the following failures:

柴油發電機組

D88尊龙  1.活塞—汽缸套密封不好,機油上竄,進入燃燒室燃燒,排氣冒藍煙。

D88尊龙  1. The piston - cylinder liner seal is bad, the oil is up, burning into the combustion chamber, the exhaust blue smoke.

D88尊龙  2.對于增壓式柴油機,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,機油竄入增壓室,隨同進氣進入汽缸。

  2. For a turbocharged diesel engine, due to low load and no-load, boost pressure is low. Easy to cause the supercharger oil seal (non-contact) sealing effect to drop, the oil into the pumping chamber, along with the air inlet into the cylinder.

  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。

D88尊龙  3. Up to the part of the cylinder oil burnt, part of the oil can't complete combustion, at the top of the valve, inlet, piston, piston ring, the place such as carbon deposit formation, and part with the exhaust. In this way, the cylinder jacket exhaust passage for oil will gradually accumulate, also can form carbon deposit.

  4.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。

  4. The supercharger turbo indoor oil accumulation to a certain degree, is seeping from the combination of the supercharger surface.

  5.長期小負荷運行,將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。

  5. Small load operation for a long time, will lead to the moving parts wear more serious, combustion engine overhaul period of early consequences such as environmental degradation.

  因此,柴油發電機組無論對自然吸氣型還是增壓機型的使用都應盡量減少低載/空載運行時間,并規定小負荷不能低于機組額定功率的25%—30%。

  Diesel generator set, therefore, no matter the naturally aspirated type or booster type use should minimize the low load/no-load running time, and the minimum load cannot be lower than 25% - 30% of the rated power unit.
