Keena Wai EGR - Nā Mea Hoolei Pono
wehewehe huahana
He ʻāpana kēia i hoʻohana ʻia i ka ʻōnaehana exhaust kaʻa-EGR cooler, ʻo ke keʻena wai ka inoa.
Hana ʻia ʻo ia me ke kila kila 304, nona nā mea maikaʻi o ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion, a me nā mea ʻē aʻe.
Nā hiʻohiʻona huahana
1.thin-walled, paʻakikī paʻakikī, maʻalahi e hana i ka deformation i ka hana hoʻolei
2.the huahana he sealing koi, no ka hoolei ana i na hemahema i ka mana o na koi kiekie
ʻO ke kūlana 2, no ke kūlana o ka paipu wai waho, ka hoʻohana ʻana i ka sila radial O-ring, no laila no ka hoʻoponopono pono ʻana i nā koi, kiʻekiʻe.
Figure 3 kūlana, no ka welding ili a me ka EGR shell kuʻihao, i mea e hōʻoia i ka brazing pass rate, no laila, no ka hana ana o ka palahalaha i kekahi mau koi;
Hōʻike 4 kūlana no ka paipu wai liʻiliʻi o waho, ma muli o ka hoʻohana ʻana i ka sila brazed ma waena o nā ʻāpana, ʻoi aku ka kiʻekiʻe o nā koi.
Keia 'ano o ka hale mea mea maʻalahi, akā, i ka hoʻomohala kaʻina hana, oluolu i ka structural wela ami, ko makou hui i loko o ka mea kūʻai mai kamaʻilio, e kiʻi i ka mea kūʻai mai 'ae, optimize i ka helehelena o ka huahana, a me ka hoʻomaka 'ana o ka lehulehu hana ma 2018, a hiki i kēia manawa hoʻomau i ka hoʻolako 'ana ma kahi o 50,000 apana no ka makahiki;
Loaʻa i kā mākou hui kahi hui hoʻomohala ʻenehana ikaika, me ka hiki ke hoʻomohala i nā ʻāpana like ʻole i ke kahua o ka hoʻolei pololei ʻana, a hāʻawi i nā lawelawe i hoʻohui ʻia mai ka hoʻolei ʻana i ka mīkini, ka hoʻoikaika ʻana no ka maikaʻi, e hoʻolako i nā mea kūʻai aku me nā huahana maikaʻi, kiʻekiʻe kiʻekiʻe a me nā lawelawe.
