柴油發電機噴油嘴卡死的原因及處理方法

  柴油發電機噴油嘴是柴油機燃料供給系統的三對精密偶件之一。它的正常使用壽命在一千小時以上。但由于使用不當,往往使用幾百小時,甚至幾十小時就磨損卡死了。

D88尊龙  Diesel engine fuel injector is one of the three pairs of diesel engine fuel supply system. Its normal service life is more than one thousand hours. However, due to improper use, often use hundreds of hours, or even tens of hours on the wear card.

D88尊龙  一、噴油嘴卡死的主要原因:

  First, the main reason for the fuel injector stuck:

  ① 柴油不清潔,高壓油管內有雜質,力出寞了噴曲器針閥偶件的磨損,使針閥偶件關閉不嚴,燃燒室內高壓燃氣反竄,燒壞針閥偶件。此外,噴油器調壓彈簧、挺桿等 零件上的臟物通過噴油器挺桿移到了噴油器針閥上部,或油路上用于防止漏油的棉繩、鉛絲經高壓油管進入噴油器,都會使針閥偶件卡死。

D88尊龙  The diesel is not clean, high pressure tubing has impurities, force out Mo wear curved spray nozzle, the needle valve is not tightly closed, the combustion chamber pressure gas anti channeling needle valve, burn. In addition, the injector pressure regulating spring, tappet parts such as on the dirt through the injector tappet moved to the upper part of the injector, or the oil used for cotton rope, to prevent leakage of the wire by high pressure oil into the injector, will make the needle valve stuck.

  ②機溫過高噴曲器冷卻不良,造虎地閥偶件卡死。而供油時間過遲、冷卻水道水垢過多或堵塞、水泵葉輪端面磨損、發動機長期超負荷等又會使發動機過熱。

  The engine temperature is too high, the cooling of the spray device is bad, so the valve parts of the tiger are stuck. The oil too late, cooling too much scale or blockage of the pump impeller and seal wear, long-term engine overload etc. will make the engine overheating.

  ③出抽閥磨損,使噴油器停止噴油時出現滴油現象,以致使噴曲嘴燃焦積炭,發生卡死的故障。

D88尊龙  The pumping out valve wear, the injector drop of oil injection stop phenomenon, so that the spray mouth curved coke burning coke, stuck fault.

  ④噴曲壓力過低,造成燃燒室內高壓燃氣反竄;

D88尊龙  The curved injection pressure is too low, resulting in high pressure gas reverse flow combustion chamber;

D88尊龙  ⑤噴油器安裝時,漏裝墊片或墊片破壞,造成漏氣,引起噴油器局部溫度過高而卡死。

D88尊龙  The installation of the injector, leakage or gasket gasket damage caused by leakage, caused by the local temperature is too high and the death card injector.

D88尊龙  ⑥零件制造方面的原因,如氣缸蓋上噴油器安裝孔與噴油器配合過緊,針閥體與氣缸蓋上的安裝孔間隙過小,氣缸蓋噴油器安裝孔加工過深等。

  The parts manufacturing reasons, such as cylinder head, the fuel injector with the tight hole and the fuel injector installation hole clearance on the cover of the needle valve body and the cylinder is too small, the cylinder cover and the fuel injector hole deep processing etc.

  二、噴油嘴卡死的修理方法:

  Two, the repair method of fuel injection nozzle:

  先將卡死的噴油嘴放入柴油或機油內加溫,然后取出用布包住,再用手鉗夾緊針閥并慢慢活動,將針閥從針閥體內取出。將少量清潔機油滴在針閥體內,使針閥在針閥 體內反復活動,直至針閥能在針閥體內活動自如。如針閥的密封面有燒傷的痕跡,應當用研磨膏進行研磨。研磨時要注意掌握研磨膏用量和研磨時間。將清洗干凈的 鐘閥偶件裝上噴油器,并調整好噴油壓力后即可重新使用。

  The first nozzle will be stuck into diesel or oil heating, and then remove the cloth, and then the clamping pliers needle and slowly remove the needle from the needle, in vivo. A small amount of clean oil droplets in the valve body, the valve body of the needle repeatedly until the needle in the activities, activities of the needle body freely. As the needle valve sealing surface burns, should be abrasive grinding paste. Grinding should pay attention to grasp the amount of grinding paste and grinding time. The cleaning of the bell valve pieces attached to the injector, and adjust the injection pressure can be re used.
