ʻO ka mea hoʻoheheʻe wahie Diesel hou 28490086 no ka Jmc Transit Qingling

ʻElua ʻano ʻano o nā ʻenekini wahie o nā ʻenekini diesel kiʻekiʻe kiʻekiʻe a me nā ʻano: pintle ʻano a me nā ʻano porous. Hoʻohana ʻia nā injectors axial needle i loko o ka vortex a i ʻole nā ​​​​keʻena puhi mua. ʻO ka helu o nā puka injection he 1, a ʻo ke anawaena aperture ma luna o 1mm. ʻO kēia ʻano o ka injector e hana hilinaʻi, a ʻaʻole maʻalahi nā puka i hoʻopaʻa ʻia e nā waihona kalapona, akā haʻahaʻa ka hana wela a ʻoi aku ka nui o ka hoʻohana ʻana i ka wahie. ʻO nā ʻenekini 125 kūloko a me 146 series diesel engine no kēia ʻāpana.

He kiʻekiʻe ka wela wela o kēia ʻano injector a ʻoi aku ka maikaʻi o ka wahie. ʻO ka mea hoʻoheheʻe wahie o ka mīkini diesel 135 series home he mau puka nozzle me ke anawaena o 0.35mm. ʻO ka hui pū ʻana o ka wahie injector he mea pololei, a ʻo kona ʻae ʻana he 0.002 ~ 0.004mm wale nō. Inā loaʻa nā mea haumia i loko o ka ʻaila diesel, e hoʻopaʻa ʻia ka valve needle. Eia kekahi, ua pili ke poʻo o ka wahie injector me ke kinoea wela kiʻekiʻe a me ke kaomi kiʻekiʻe i loko o ke keʻena puhi ahi no ka manawa lōʻihi, e hoʻonui mālie a hoʻololi i ka valve needle, a pili i ka hana maʻamau o ka locomotive. Ke hana nei ka injector, hoʻopili pinepine ʻia ka ʻili o ka cone sealing o ke kino valve needle e ka valve needle, i hui pū ʻia me ka hoʻomau mau ʻana o ke kahe ʻaila kiʻekiʻe mai kēia wahi, e ʻike ʻia ka ʻili o ka cone i nā ʻōpala a me nā kiko - e nalowale ka sila, a hoomaka e kulu aila . Ke haʻahaʻa ka mahana o ka mīkini, e hoʻokuʻu ka uahi keʻokeʻo i ka ʻili o ka mīkini, a i ka wā e piʻi ai ka mahana o ka mīkini, e lilo ia i uahi ʻeleʻele, a i kekahi manawa e hoʻokuʻu ka paipu hoʻopau i nā leo puhi ʻole.
