發(fā)電機噴油嘴卡死的主要原因及修理
焦化發(fā)電機組噴油嘴是焦化機燃料供給系統的三對精密偶件之一，但由于使用不當，往往使用幾百小時(shí)，甚至幾十小時(shí)就磨損卡死了。下面來(lái)講講發(fā)電機噴油嘴卡死的主要原因及修理。
The fuel injection nozzle of coking generator is one of the three pairs of precision parts in the fuel supply system of coking machine, but due to improper use, it is often worn and stuck after hundreds of hours, or even dozens of hours. Next, let's talk about the main causes and repair of the stuck fuel injection nozzle of the generator.
噴油嘴卡死的主要原因：
Main reasons for stuck fuel injection nozzle:
①焦化不清潔，高壓油管內有雜質(zhì)，力出寞了噴曲器針閥偶件的磨損，使針閥偶件關(guān)閉不嚴，燃燒室內高壓焦化反竄，燒壞針閥偶件。
① The coking is not clean, and there are impurities in the high-pressure oil pipe, which causes the wear of the needle valve coupling parts of the curve ejector, so that the needle valve coupling parts are not tightly closed, and the high-pressure coking in the combustion chamber is reversed, burning the needle valve coupling parts.
②機溫過(guò)高噴曲器冷卻不良，造虎地閥偶件卡死。而供油時(shí)間過(guò)遲、冷卻水道水垢過(guò)多或堵塞、水泵葉輪端面磨損、發(fā)動(dòng)機長(cháng)期超負荷等又會(huì )使發(fā)動(dòng)機過(guò)熱。
② The temperature of the machine is too high, the cooling of the koji sprayer is poor, and the coupling parts of the zaohudi valve are stuck. The engine will overheat if the oil supply time is too late, the cooling water channel is too dirty or blocked, the end face of the water pump impeller is worn, and the engine is overloaded for a long time.
③出抽閥磨損，使噴油器停止噴油時(shí)出現滴油現象，以致使噴曲嘴燃焦積炭，發(fā)生卡死的故障。
③ The exhaust valve is worn, which causes the fuel injector to drip when it stops fuel injection, resulting in coke and carbon deposition on the curved nozzle and jamming.
④?chē)娗鷫毫^(guò)低，造成燃燒室內高壓焦化反竄；
④ The injection pressure is too low, causing high-pressure coking reverse channeling in the combustion chamber;
⑤噴油器安裝時(shí)，漏裝墊片或墊片破壞，造成漏氣，引起噴油器局部溫度過(guò)高而卡死。
⑤ When the fuel injector is installed, the gasket is missing or damaged, resulting in air leakage, causing the local temperature of the fuel injector to be too high and stuck.
噴油嘴卡死的修理方法：
Repair method for stuck fuel injection nozzle:
先將卡死的噴油嘴放入焦化或機油內加溫，然后取出用布包住，再用手鉗夾緊針閥并慢慢活動(dòng)，將針閥從針閥體內取出。
First put the stuck fuel injector into coking or engine oil for heating, then take it out and wrap it with cloth, then clamp the needle valve with pliers and move it slowly, and take the needle valve out of the needle valve body.
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(dòng)，直至針閥能在針閥體內活動(dòng)自如。如針閥的密封面有燒傷的痕跡，應當用研磨膏進(jìn)行研磨。
Drop a small amount of clean engine oil into the needle valve body to make the needle valve move repeatedly in the needle valve body until the needle valve can move freely in the needle valve body. If the sealing surface of the needle valve has burn marks, it should be ground with grinding paste.
研磨時(shí)要注意掌握研磨膏用量和研磨時(shí)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。
When grinding, pay attention to the amount of grinding paste and grinding time. Install the cleaned bell valve coupling on the fuel injector and adjust the injection pressure before reuse.
