Nozzle Injector hou Dlla150pn315 no Mitsubishi Engine

Hoʻohana ʻia ke kaʻina hana wili pālua no nā ʻāpana valve needle, a ʻo ka roughness ʻili he .025μm. He liʻiliʻi loa ka hoʻomaʻemaʻe paʻa ʻana o ka huila valve, maʻamau 1 ~ 4μm. I ka hana maoli ʻana o ka lua o ka nila, ma muli o ke kiʻekiʻe o ka wahie, a me ka neʻe ʻana a me ka deformation ma waena o nā kāne, ua hoʻokumu ʻia ka lubrication wai ma waena o nā kāne. Wahi a ke kumumanaʻo o ka loiloi lubrication, he mana nui ka viscosity o ka aila wahie i nā hiʻohiʻona lubricating o ka wahie aila, a i ka wā e mau ai nā kūlana hana, ʻo ka viscosity o ka ʻaila lubricating e hoʻoholo i ka mānoanoa o ka lubricating oil film. Wahi a ka manaʻo o tribology, ʻo ka lubrication o ka hui ʻana o ke kui kui he lubrication palena. I ka lubrication palena, ma muli o ka like ʻole o ka ʻili o ka male, ʻo ka ʻaila kiʻiʻoniʻoni ma waena o nā piko pili e lawe i kahi ʻāpana o ka ukana, no laila he hopena koʻikoʻi ka viscosity o ka wahie i ka lubrication a me ka hiki ke amo o ka hui valve needle. .

Hoʻopili ʻia ka hui ʻana o ka nilala i ke ʻano o ka lubricating ponoʻī diesel, a ua hoʻokumu ʻia ke kiʻi ʻaila i loko o ka lua male o ka hui ʻana o ka nila ma o ka hoʻohana ʻana i ka leakage o ka aila diesel kiʻekiʻe, e pale ana i ka hoʻopili pololei ʻana o ka ʻili o ka ʻaila. kiʻiʻoniʻoni. ʻO ka maʻiʻo o nā mea paʻa i ka ʻaila diesel e hoʻoholo i ka hiki ke lubricating o ka aila diesel. Aia nā lubricants maoli i ka aila diesel, e like me sulfides a me polycyclic aromatic hydrocarbons. Ma muli o ke kaʻina hana hydrogenation koʻikoʻi a me ka mālama desulfurization maʻamau i ke kaʻina hana diesel, he haʻahaʻa loa ka ʻike o nā pūhui polar wear-resistant, a he liʻiliʻi hoʻi ka ʻike o ka polycyclic a me ka bicyclic aromatic hydrocarbons, no laila ka hiki ke lubricating ponoʻī. ʻO ka aila diesel he haʻahaʻa loa. ʻokoʻa.
