I roto i ngā taputapu hanga pepa, kāore i te maha ngā whakaahuatanga o ngā "whakamaroke Yankee" i roto i ngā "kirokaramu". Engari, ko ngā tawhā pēnei i te whānui (hei tauira, 1.5m, 2.5m), te roa, te pēhanga mahi, me te matotoru o ngā rauemi he mea noa ake. Mena ko te "3kg" me te "5kg" i konei e pā ana ki te pēhanga mahi o te whakamaroke Yankee (waeine: kgf/cm², arā, te kaha-kirokaramu mō ia henimita tapawha), ko ō rātou rerekētanga matua ka kitea nuitia i roto i ngā āhuatanga e whai ake nei:
- Ngā Pāmahana Mahi Rerekē
Ko te whakamahana o ngā whakamaroke Yankee e whakawhirinaki ana ki te mamaoa kua mākū i roto, ā, e pā tika ana te pēhanga mamaoa ki te pāmahana (e whai ana i te kōpiko āhuatanga mamaoa):
Ko te pāmahana o te mamaoa kua mākū i te 3kgf/cm² (tata ki te 0.3MPa) he tata ki te 133℃;
Ko te pāmahana o te mamaoa kūkū i te 5kgf/cm² (tata ki te 0.5MPa) he tata ki te 151℃.
Ka pā tika te rerekētanga o te pāmahana ki te pai o te whakamaroke o te pepa: ka teitei ake te pēhanga (ā, ka teitei ake te pāmahana), ka nui ake te wera e whakawhitia ana ki te pepa i ia wā, ka tere ake te tere o te whakamaroke. Nā tēnei ka pai mō ngā pepa e hiahia ana kia pai te whakamaroke (pērā i te pepa tauera me ngā mīhini pepa tere-rahi).
- Te Rerekētanga o te Whai Huatanga Whakamaroke me te Whakapaunga Pūngao
Te whai huatanga o te whakamaroke: Ko te mīhini whakamaroke Yankee 5kgf/cm² te pehanga, me te pāmahana teitei ake, he nui ake te rerekētanga pāmahana ki te pepa, ka tere ake te whakawhiti wera. Ka taea e ia te mimiti i te makuku i te wā kotahi, ā, ka urutau ki ngā tere oma o te mīhini pepa teitei ake.
Te utu mō te whakapaunga pūngao: Ko te mamaoa i te pēhanga 5kgf/cm² me nui ake te putanga o te kōhua, ā, ka nui ake te whakapaunga pūngao (pērā i te waro, te hau māori, me ētahi atu). He iti ake te whakapaunga pūngao o te mamaoa i te pēhanga 3kgf/cm², ā, he pai mō ngā āhuatanga kāore e tino hira te tere whakamaroke (pērā i ngā mīhini pepa tere-iti me ngā momo pepa matotoru).
- Ngā Momo Pepa me ngā Tukanga e Tika ana
Pēhanga 3kgf/cm² Whakamaroke Yankee: Nā te iti o te pāmahana, he pai mō ngā momo pepa tairongo wera (pērā i ētahi pepa ware pi, ngā pepa he paninga ka ngāwari ki te whakarerekē i te wera) ngā pepa matotoru rānei e hiahia ana kia puhoi te whakamaroke kia kore ai e piko me te ngatata (pērā i te pepa pepa, te pepa kraft matotoru).
Pēhanga 5kgf/cm² Whakamaroke Yankee: Ki te pāmahana teitei ake, he pai mō te pepa tauera (pērā i te niupepa, te pepa tuhituhi), ngā pepa ahurea i hangaia i ngā tere tiketike, me ētahi atu. Ka taea e ia te tango wawe i te makuku, te whakarite kia pai te mahi a te mīhini pepa, me te whakaiti i te mōrearea o te pakaru o te pepa mā te whakapoto i te wā noho o te pepa i roto i te tukanga whakamaroke.
- Ngā Whakaritenga Rerekē mō ngā Rauemi Taputapu me te Haumaru
Ahakoa he iti te pēhanga o te 3kgf/cm² me te 5kgf/cm² (i te nuinga o te wā, he teitei ake te pēhanga hoahoa o te whakamaroke Yankee i te pēhanga mahi me te tawhē haumaru), ko te pēhanga teitei ake te tikanga he paku teitei ake ngā whakaritenga mō te kaha o te rauemi, te mahi hiri, me te matotoru o te pakitara o te whakamaroke Yankee:
Me whakarite te rauemi rango o te mīhini whakamaroke Yankee 5kgf/cm² pēhanga (pēnei i te rino maka, te rino maka koranu) kia pumau i raro i te pēhanga teitei ake. He kaha ake te tika o te tukatuka o ngā hononga whakarewa, ngā hiri flange, me ētahi atu wāhanga kia kore ai e turuturu te mamaoa.
Me tutuki e rāua ngā ture haumaru mō te oko pēhanga, engari ko te whakamaroke Yankee pēhanga 5kgf/cm² ka nui ake pea ngā tirotiro auau me ngā tirotiro pakari ake (pērā i ngā whakamātautau wai-pūmau).
Whakarāpopototanga
Ko ngā mīhini whakamaroke Yankee e whakamahi ana i te pehanga 3kgf/cm² me te 5kgf/cm² ka whakarerekē i te pāmahana me te pai o te whakamaroke mā roto i ngā rerekētanga pehanga mamaoa. Ko ngā rerekētanga matua kei roto i te tere whakamaroke, te utu whakapaunga pūngao, me ngā momo pepa e tika ana. Me arotake whānuitia te kōwhiringa i runga i te tere o te mīhini pepa, ngā āhuatanga o te momo pepa, te tahua whakapaunga pūngao, me ētahi atu. Ehara i te mea he pai ake te pehanga teitei ake; me ōrite ki ngā whakaritenga o te tukanga whakaputa.
