燃油发电机组喷油嘴卡死的原因有哪些?

返回 2021.04.02 来源:http://www.huannengpower.com
导致柴油发电机组喷油嘴卡死的原因主要有:柴油不清洁;出抽阀磨损;喷油器安装时,漏装垫片或垫片破坏;机温过高喷曲器冷却不良等几个原因造成,以下是具体介绍:
The main causes of diesel generator nozzle sticking are as follows: the diesel oil is not clean; the outlet valve is worn; the gasket is missing or damaged when the injector is installed; the engine temperature is too high, and the cooling of the injector is poor
1、柴油不清洁
1. Diesel oil is not clean
柴油不清洁,高压油管内有杂质,导致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 dirty diesel oil and impurities in the high-pressure oil pipe lead to the wear of the needle valve couple of the injector, which makes the needle valve couple not close tightly, and the high-pressure gas in the combustion chamber reverses and burns out the needle valve couple. In addition, the dirt on the pressure regulating spring and tappet of the fuel injector moves to the upper part of the needle valve of the fuel injector through the tappet of the fuel injector, or the cotton rope and lead wire used to prevent oil leakage on the oil circuit enter the fuel injector through the high-pressure oil pipe, which will make the needle valve parts stuck.
2、出抽阀磨损
2. The outlet valve is worn
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。
The abrasion of the extraction valve makes the injector drip when it stops injecting oil, which causes the nozzle to burn coke and deposit carbon and block.
3、喷油器安装时,漏装垫片或垫片破坏
3. When the injector is installed, the gasket is missing or damaged
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 gasket is missing or damaged, resulting in air leakage, causing the injector local temperature is too high and stuck.
4、喷曲压力过低
4. Too low bending pressure
喷曲压力过低,造成燃烧室内高压燃气反窜。
The jet pressure is too low, which results in the high pressure gas channeling in the combustion chamber.
5、机温过高喷曲器冷却不良
5. The temperature of the machine is too high and the cooling of the bender is not good
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。
The temperature of the machine is too high, the cooling of the bender is not good, and the parts of the valve are stuck. However, too late oil supply time, too much or blocked scale in cooling channel, worn end face of water pump impeller and long-term overload of engine will make the engine overheat.
6、零件制造不合适
6. Improper manufacturing of parts
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 reasons of parts manufacturing, such as the tight fit between the injector mounting hole on the cylinder head and the injector, the small clearance between the needle valve body and the mounting hole on the cylinder head, and the deep machining of the injector mounting hole on the cylinder head.
