D88尊龙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。
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) 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.
D88尊龙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) the low pressure of the spray curve causes the anti - channeling of the high pressure gas in the combustor.
D88尊龙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.
D88尊龙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..
