发电机喷油嘴卡死的主要原因及修理

焦化发电机组喷油嘴是焦化机燃料供给系统的三对精密偶件之一,但由于使用不当,往往使用几百小时,甚至几十小时就磨损卡死了。下面来讲讲发电机喷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.
喷油嘴卡死的主要原因:
Main reasons for stuck fuel injection nozzle:
①焦化不清洁,高压油管内有杂质,力出寞了喷曲器针阀偶件的磨损,使针阀偶件关闭不严,燃烧室内高压焦化反窜,烧坏针阀偶件。
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机温过高喷曲器冷却不良,造虎地阀偶件卡死。而供油时间过迟、冷却水道水垢过多或堵塞、水泵叶轮端面磨损、发动机长期超负荷等又会使发动机过热。
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出抽阀磨损,使喷油器停止喷油时出现滴油现象,以致使喷曲嘴燃焦积炭,发生卡死的故障。
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喷曲压力过低,造成燃烧室内高压焦化反窜;
④ The injection pressure is too low, causing high-pressure coking reverse channeling in the combustion chamber;
⑤喷油器安装时,漏装垫片或垫片破坏,造成漏气,引起喷油器局部温度过高而卡死。
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.
喷油嘴卡死的修理方法:
Repair method for stuck fuel injection nozzle:
先将卡死的喷油嘴放入焦化或机油内加温,然后取出用布包住,再用手钳夹紧针阀并慢慢活动,将针阀从针阀体内取出。
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.
将少量清洁机油滴在针阀体内,使针阀在针阀体内反复活动,直至针阀能在针阀体内活动自如。如针阀的密封面有烧伤的痕迹,应当用研磨膏进行研磨。
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.
研磨时要注意掌握研磨膏用量和研磨时间。将清洗干净的钟阀偶件装上喷油器,并调整好喷油压力后即可重新使用。
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.
