Ngā Pātai Auau
He aha te rerekētanga matua i waenga i ngā here taura raka-ā-ia-anō pōro me ngā here taura maitai kore waikura āhua arawhata?
Ko te rerekētanga matua kei roto i te tikanga raka me tōna pānga ki te kaha kume me te ātete wiri. Ka whakamahia e ngā here raka-ā-ringa pōro he pōro maitai kore waikura e piri ana ki roto i te awaawa whakarara, ka hanga he raka whakamua e kaha ana i raro i te kawenga, ā, ka eke ki te 200-250 pauna o te kaha kume i roto i te whānui 7.9 mm. Ka whakamahia e ngā here momo arawhata he paihere puna e whakauru ana i ngā awaawa motuhake kua tāia ki roto i te whitiki, e whakarato ana i te raka whakarerekē engari he iti ake te kaha i te 100-150 pauna. I kitea e mātou ka mau tonu te raka o ngā here raka-ā-ringa pōro ki te 92% i muri i te 1,000 hāora o te whakamātautau wiri, ko ngā here momo arawhata ia e mau tonu ana ki te 78%. Mō ngā tono taumaha me te wiri nui, ka tūtohu tonu mātou i te raka-ā-ringa pōro hei whiringa pai ake. Mō ngā tāutanga whakarerekē i roto i ngā taiao pai, ka tukuna e ngā here momo arawhata he mahi tika i te utu waeine iti ake.
Ko tēhea momo here taura te mea pai mō ngā taiao wiri waka?
Ka tūtohu mātou i ngā here taura maitai kore-waikura raka-parirau mō te nuinga o ngā mahi motuka nā te mea he pai te taurite o te kaha kume (120-180 lbs i te whānui 7.9 mm) me te whakaiti i te wiri. Ka tohatohahia e ngā parirau kua whakapikohia te kaha wiri puta noa i te wāhi pa whānui, ka whakaiti i te ahotea tihi i te pūwāhi raka, ā, ka tukuna he 87% te pono o te raka i muri i te 1,000 hāora o te whakamātautau wiri. Mō ngā rohe wera nui e tata ana ki ngā manifolds hau me ngā turbochargers, ka tohua e mātou ngā here raka-whaiaro pōro nā te mea ko tō rātou ātete pāmahana teitei ake me te pupuri wiri 92% ka whakarato i te taha haumaru tāpiri. Ko ngā miihini motuka e mahi tahi ana me mātou ka whakamahi i ngā here raka-parirau mō ngā waea kāpini me te chassis, me ngā here raka-whaiaro pōro mō ngā mahi taha o te wāhi miihini me te hau. Ka tukuna e mātou ngā momo e rua me ngā tuhinga ture SAE International katoa.
Ka taea te whakamahi anō i ngā here taura kowiri tira āhua arawhata i muri i te tāutanga?
Ka taea te whakamahi anō i ngā here momo arawhata, ā, koinei tētahi o ngā painga matua o ēnei here i roto i ngā tono e hiahia ana kia whakatikatikaina pinepine. Ka taea te wetewete i te hononga o te poupou puna mai i ngā kaupae arawhata, kia taea ai e te kaiwhakauru te neke i te here ki tētahi tūranga hou, ka hoki anō ki tētahi awaawa rerekē. Heoi, ka tohutohu mātou kia kaua e whakamahi anō i ngā here arawhata neke atu i te toru ki te rima ngā huringa nā te mea ka puta he tohu pakaru i ngā mata o te poupou me te awaawa ka whakaiti i te pono o te raka. I roto i ā mātou whakamātautau, ka whakaatuhia e ngā here arawhata kua whakamahia anō he whakahekenga 12-18% i roto i te kaha kume i muri i ngā huringa whakatikatika e rima. Mō ngā tono e tumanakohia ana kia nekehia te tūnga anō, pērā i te whakatūnga HVAC me ngā whakaurunga hanga rangitahi, ko ngā here momo arawhata tonu tā mātou whiringa ahakoa tēnei herenga. Kia oti te whakatūnga o te pūnaha, ā, kia whakaritea ngā tūranga whakamutunga, ka tūtohu mātou kia whakakapia ngā here kua whakamahia anō ki ngā waeine hou hei whakarite i te pono mō te wā roa.
He aha te momo maitai kore waikura me tohu mō ngā here taura moana me tai?
E tino taunaki ana mātou i te maitai kore waikura 316, 316L rānei mō ngā mahi moana me ngā mahi taiwhenua katoa. Ko te 2-3% o te molybdenum i roto i te karaehe 316 e whakarato ana i te ātete nui ki te waikura me te kapiti i puta mai i te hauota, ki te whakataurite ki te karaehe 304. I roto i ā mātou whakamātautau rehu tote e ai ki te ASTM B117, kāore he waikura e kitea ana i roto i ngā here taura karaehe 316 i muri i te 1,000 hāora, ko ngā here karaehe 304 ka tīmata te whakaatu i te waikura mata i te 500-600 hāora. Mō ngā papaaho taiwhenua, ngā whakaurunga raro moana, me ngā whare ahumahi takutai moana, ka tukuna motuhaketia e mātou te karaehe 316L puta noa i ngā momo tikanga raka e toru. Ko te tohu L (iti te waro) ka whakapai ake i te ātete ki te waikura o te rohe whakarewa, he mea nui ina pa ngā here ki ngā tautoko paipa whakarewa, ki te maitai hanganga rānei. E taunaki ana hoki mātou i ā mātou here 316L pania ki te epoxy mō ngā mahi e pa ana te here taura ki ngā wāhanga konumohe, ki te maitai waro rānei, nā te mea ka ārai te paninga i te waikura galvanic i roto i te hau moana whai-irahiko.
Me pēhea taku tatau i te whānui me te roa o te here taura e tika ana mō taku tono?
Ka ārahi mātou i ā mātou kiritaki mā roto i tētahi tukanga tatau māmā e whai whakaaro ana ki te whānui o te paihere, ngā whakaritenga kawenga, me ngā āhuatanga haumaru. Tuatahi, inehia te whānui o waho mōrahi o te paihere taura, o te huihuinga ngongo rānei, tae atu ki tētahi whakamarumaru, takai rānei. Tāpirihia te 10-15% ki tēnei whānui hei whakatau i te porowhita here iti rawa, kātahi ka wehea kia rua hei whiwhi i te roa here whai hua iti rawa. Mō te kōwhiringa whānui, wehea tō kaha kume e hiahiatia ana e ngā uara whānui-mō ia i roto i ā mātou ripanga whakatakotoranga. Hei tauira, ki te hiahia tō tono ki te 300 pauna o te mana pupuri, me whiriwhiri e koe he here raka-ake pōro 12.0 mm (kua whakatauria 400-500 pauna) hei whakarato i tētahi tawhē haumaru e tika ana. Ka tūtohu tonu mātou kia whakamahia he tauwehe haumaru iti rawa o te 1.5x mō ngā kawenga tūmau me te 2.0x mō ngā tono hihiri, wiri rānei. Ka taea e tā mātou tīma hangarau te mahi i ēnei tataunga māu mēnā ka whakaratohia e koe tō whānui paihere me ngā āhuatanga kawenga, ā, ka tūtohu mātou i te hua tika mai i tā mātou putumōhio e tutuki ana i ō whakaritenga.
He aha ngā tiwhikete me ngā pūrongo whakamātautau e whakaratohia ana e koe mō ngā ota here taura kowiri tira?
Ka whakaratohia e mātou he kete tuhinga whānui mō ia uta e whakauru ana i ngā tiwhikete mira rauemi e whakaū ana i te hanganga matū me ngā āhuatanga miihini, ngā pūrongo whakamātautau kume mai i tā mātou taiwhanga whakamātautau kua whakatikatikaina kia taea te whai i ngā paerewa NIST, ngā pūrongo whakamātautau rehu tote mō te whakamana ātete ki te waikura, me ngā tiwhikete e tutuki ana ki ngā paerewa UL, SAE, me ngā paerewa kua tohua e te kiritaki. Mō ngā ota rererangi me te tiaki whenua, ka whakaratohia hoki e mātou he tuhinga whai rauemi katoa mai i te koiri mata ki te hua kua oti, ngā pūrongo tirotiro tuhinga tuatahi, me ngā tiwhikete tukanga motuhake. Ka mau tonu mātou i te tiwhikete ISO 9001 puta noa i ā mātou mahi hanga, ā, ka arotakehia ā-tau tā mātou pūnaha whakahaere kounga e ngā rōpū tuatoru kua whakamanahia. Ka taea e ngā kaihoko te tono pūrongo whakamātautau motuhake, ngā tiwhikete rānei i te wā o te ota, ā, ka whakatutukihia e mātou ngā whakaritenga whakamātautau ritenga mō ngā kirimana uara nui.
