Na te mea he ngawari te whakauru o te acetylene ki te hau, a ka taea te hanga i nga ranunga pahū, ka puta te ngingiha me te pahūtanga ina kitea ki te mura o te ahi me te kaha wera nui.Kua whakatauhia ko te mahi o nga ipu acetylene me tino rite ki nga ture haumaru.He aha nga korero mo te whakamahi i nga rango acetylene?
1. Me whakauru te pounamu acetylene ki te aukati whakamarumaru motuhake me te whakaheke pehanga.Mo te waahi mahi karekau me te neke ake, me whakanoho ki runga i tetahi motuka motuhake.
2. Ka tino whakakorehia te patoto, te tukinga me te whakamahi i nga wiri kaha, kia kore ai e totohu te whakakii porous i roto i te pounamu me te hanga i te kohao, ka pa ki te rokiroki o te acetylene.
3. Me whakanoho te pounamu acetylene ki runga ki runga, a ka tino rahuitia te whakamahi takoto.Na te mea ka rere te acetone i roto i te pounamu me te acetylene ina whakamahia ana e takoto ana, ka rere ano ki roto i te ngongo rafter ma te whakaheke pehanga, he tino kino.
4. Whakamahia he wihi motuhake hei whakatuwhera i te puoto hau acetylene.I te whakatuwheratanga o te pounamu acetylene, me tu te kaiwhakahaere ki muri i te taha o te tauranga valve me te ata mahi.Ka tino whakakorehia te whakamahi i te hau i roto i te pounamu.Me pupuri te 0.1~0.2Mpa i te takurua me te pehanga toenga 0.3Mpa i te raumati.
5. Ko te pehanga whakahaere kia kaua e neke atu i te 0.15Mpa, me te tere o te whakawhiti hau kia kaua e neke atu i te 1.5 ~ 2 mita cubic (m3) / haora · pounamu.
6. Ko te mahana o te rango acetylene kaua e neke ake i te 40°C.A ape i te rongo i te raumati.Na te mea he tiketike rawa te pāmahana i roto i te pounamu, ka whakahekehia te whakarewatanga o te acetone ki te acetylene, ka piki ake te pehanga o te acetylene i roto i te pounamu.
7. Kaua te pounamu acetylene e tata ki nga puna wera me nga taputapu hiko.
8. Ka tio te paera pounamu i te takurua, ka tino rahuitia te whakamahi ahi hei tunu.Mena e tika ana, whakamahia te wera i raro iho i te 40 ℃ hei whakamaroke.
9. Me pono te hononga i waenga i te whakaheke pehanga acetylene me te paera pounamu.Ka tino whakakorehia te whakamahi i raro i te rerenga hau.Ki te kore, ka hanga he ranunga o te acetylene me te hau, ka pahū ina pa ana ki te mura ahi.
10. Kare e tika kia whakamahia ki te waahi karekau te hau me te rauropi, kaua hoki e utaina ki runga i nga mea whakamaarama pera i te rapa.Me neke ake i te 10m te tawhiti i waenga i te puoto acetylene me te puoto hāora.
11. Mena ka kitea he hee te puera hau, kaua te kaiwhakahaere e whakatika me te kore e whakamanahia, me whakamohio atu ki te kaitirotiro haumaru kia whakahokia ki te whare hau mo te tukatuka.
