柴油发电机组负载过低会导致哪些故障

来源:http://www.huannengpower.com   发布于:2017-04-11

  柴油发电机组机体多处都是采用压力密封的形式,如汽缸套、活塞、活塞环间,增压器、增压器转子轴间,这种密封一般在发动机有约1/3负荷时,才充分发挥作用,若发电机组长时间低负载下运行会出现以下故障:发电机组  Diesel generating set is more than the body in the form of pressure seal, such as cylinder, piston ring, piston, turbocharger, supercharger rotor shaft, this seal in the engine, about one-third of the load to give full play to the role, if the generator group leader time under low load operation will appear the following failures:

  1.冒蓝烟

  Blue smoke coming 1.

  活塞、汽缸套密封不好,机油上窜,进入燃烧室燃烧,排气冒蓝烟。

  Piston and cylinder liner seal is bad, the oil is up, burning into the combustion chamber, the exhaust blue smoke.

  2.机油乱窜

  2. The oil straggling

  对于增压式柴油机,由于低载、空载,增压压力低。容易导致增压器油封的密封效果下降,机油窜入增压室,随同进气进入汽缸。

  For supercharged diesel engine, due to low load and no-load, boost pressure is low. Easily resulting in a decline in the sealing effect of the turbocharger oil seal, oil into the pumping chamber, along with the air inlet into the cylinder.

  3.积炭

  3. The carbon deposit

  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。

  Is 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 the formation of coke, and part with the exhaust. In this way, the cylinder jacket exhaust passage for oil will gradually accumulate, also can form carbon deposit.

  4.渗漏

  Leakage of 4.

  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。

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

  5.部件磨损

  5. Part wear

  长期低负荷运行,将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。

  Long-term low load operation, will lead to the moving parts wear more serious, combustion engine overhaul period of early consequences such as environmental degradation.
