E rua nga whakamahinga matua o te putorino parahi i roto i te whakamahana rangi: (1) te hanga whakawhiti wera.Pērā i te whakaetonga e whakamahia nuitia ana, te condenser, e mohiotia ana ko “te taputapu e rua”;(2) Te hanga paipa hono me nga taputapu.Na ko te ngongo parahi e kiia ana ko te "waa toto", "te oko toto" pai me te kino ka whakatau tika i te kounga o te hau.Na reira, te kounga o te putorino parahi fehokotaki'anga te hoki tangohia tino.I tenei ra ka tohatohahia e matou he tuhinga e pa ana ki te whakahiato ngongo parahi o te whakamahana hau whakawera whakawhiti wera.
Te mahi whakarite
1. Pānuihia me te mohio ki nga pikitia hanga;
2, te tirohanga o te waahi hanga - ki te kite mena kei te waahi hanga nga tikanga mahi hanga;
3. Te whakarite paipa me nga taputapu;
4. Te whakarite taputapu me nga taputapu ine - oxygen-acetylene, cutter, hacksaw, hama, wrench, level, ine ine, file, etc.
2. Te tukanga whakauru
1) Whakatika paipa parahi: patoto marie i te tinana paipa me te hama rakau hei whakatika i te waahanga paipa ma ia waahanga.I te wa o te whakatikatika, kia tupato kia kaua e nui rawa te kaha, kaua e puta he tohu hama, he rua, he karawarawa, he tohu taratara ranei i runga i te mata o te paipa.
2) te tapahi paipa: ka taea te whakamahi i te tapahi paipa parahi ki te hacksaw, te miihini, te tapahi paipa parahi, engari kaua te hāora - te tapahi acetylene.Tukatuka riu putorino parahi ma te whakamahi i te konae, te miihini beveling ranei, engari kaua te hāora – te tukatuka tapahi ahi acetylene.Me whakamahi te papa rakau ki nga taha e rua o te vise mo te awhi i te paipa parahi kia kore ai e tope te paipa.
3, mutu horoi
Kaua he hinu, he waikura, he paru, he puehu ranei i runga i te mata o te ngongo parahi kua whakauruhia ki roto i te hononga, ki te kore ka tino pa ki te mahi fehokotakitanga o te kaitahuri ki te whakarewa turanga ka puta he koha.Na reira, me horoi te mata ki etahi atu whakarewa pararopi.Ko te hononga putorino parahi te tikanga kaore he paru, mena he paraihe waea parahi me te mutunga tukatuka paraihe waea maitai, kaore e taea te tukatuka me etahi atu taputapu poke.
Whakamahia he pepa kirikiri hei tango i te hinu, te waikura, te piro, me te puehu i te mata o te hononga ki te wahi e whakaurua ai te ngongo parahi.
