He maha ake nga reera Hainamana kei te kaweake ki nga whenua rereke huri noa i te ao, katahi ka kore te nuinga o nga kaihoko kee e mohio ki te hiranga o te nama takirere o Haina, i tenei ra ka kawea koe ki tetahi maaramatanga motuhake, ka taea e te tumanako te awhina i o taatau kaihoko.
I Haina, ka nui ake te ahua o nga reera me nga taonga, he nui ake te uaua o te whakarite i nga tauira takirere;Ko nga tauira takirere me tohu te momo o te takirere, te aratau taraiwa, te ahua hononga, nga ahuatanga hanganga, te pehanga ingoa, nga taputapu mata hiri, nga taonga o te tinana me etahi atu waahanga.Ko te whakatauira tauira o te takirere mo te hoahoa taki, te kowhiri, te tohatoha, he huarahi watea hei tuku i nga kaiwhakamahi ki te tiro ki te papaa ingoa ka mohio ki te hanganga o tetahi momo takirere, taonga me nga ahuatanga.
Inaianei me tango he tauira:
D341X-16Q, te tikanga ①Rererererererere-②Worm Gear whakahaere-③Momo Flange rua-④Hanganga Concentric-⑤PN16-⑥Ductile Iron.

Te mahi o te tautuhi takirere
Ko te tohu o te whaa i te kore o nga tuhi takirere, kua ngaro te papa ingoa me nga waahanga takirere kaore i te oti, he mea nui te whakamahi tika o nga riipene, nga waahanga raima, te whakatikatika me te whakakapi i nga waahanga takirere he mea nui.Inaianei ko te tohu tohu, tohu rauemi me te tohu takirere kua whakaahuatia i raro nei:
Ko te whakamahinga o te "mohiotanga taketake o te takirere" i ako i te matauranga, e ai ki te papa ingoa me te tohu i runga i te paera me te paera ki te tae peita.Ka taea e koe te tautuhi tika i te waahanga o te paera, te hanga hanganga, te rawa, te diameter ingoa, te pehanga ingoa (te pehanga mahi ranei), te papaaho urutau, te pāmahana me te ahunga kati.
1.Ka mau te papa ingoa ki runga i te tinana takirere, i te wira ringaringa ranei.Ko nga raraunga kei runga i te papa ingoa kua oti ake, e whakaatu ana i nga ahuatanga taketake o te waahi.E ai ki te kaihanga i runga i te nameplate, ki te kaiwhakanao mo te takirere mau wahi tuhi me te mōhiohio;kia rite ki te ra o te wheketere mo te whakatikatika;kia rite ki te nameplate whakarato nga tikanga o te whakamahi, ki te whakatau i te whakakapinga o gaskets, rauemi pereti takirere me puka me te ki te whakatau i te whakakapinga o te tahi atu wahi takirere o te rauemi.
2.Ka whakamahia te tohu ki te maka, te reta me etahi atu tikanga i roto i te tinana takirere e tohu ana i te pehanga nominal valve, te pehanga mahi, te tohu tohu me te ahunga rerenga reo.
3.Valve he momo tohu tohu tuwhera-kati nga tohutohu, kua whakatuwherahia te tauine rangatira, tohu ranei i te whakatuwhera me te kati o te pere.Kua tapaina nga reera kaareti, nga maru kuaha kakau pouri me nga tohutohu whakawhiti i te pito o runga o te wira-a-ringa ka tapaina he pere e tohu ana ki te huarahi o te tuwhera-kati.
