发电机的润滑喷油嘴卡死要求有哪些?

① 柴油不清洁,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,燃烧室内高压燃气反窜,烧坏针阀偶件。此外,喷油器调压弹簧、挺杆等 零件上的脏物通过喷油器挺杆移到了喷油器针阀上部,或油路上用于防止漏油的棉绳、铅丝经高压油管进入喷油器,都会使针阀偶件卡死。

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 cooling of the machine with high temperature and high temperature is not good. The oil supply time is too late, the cooling water channel is too much or clogged, the end face of the pump is worn and the engine is overloaded for a long time, and the engine will overheat.

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。

When the pumping valve is worn out, the oil drop phenomenon occurs when the injector stops injecting oil, so as to cause the coke nozzle to burn coke and accumulate coke, and the failure of card death occurs.

④喷曲压力过低,造成燃烧室内高压燃气反窜;

(4) the low pressure of the spray curve causes the anti - channeling of the high pressure gas in the combustor.

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。

When the injector is installed, the leakage of the gasket or gasket is damaged, causing air leakage and causing excessive local temperature of the injector to die.

⑥零件制造方面的原因,如气缸盖上喷油器安装孔与喷油器配合过紧,针阀体与气缸盖上的安装孔间隙过小,气缸盖喷油器安装孔加工过深等。

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..
