He maha ngā āhuatanga e pāngia ana te roa o te ora o ngā pūwero teihana whakakī hinu hauwai. I te nuinga o te wā, ko te roa o te ora he 10-20 tau, engari ka rerekē pea te āhua o te mahi nā ēnei āhuatanga:
Kotahi, momo me te hoahoa o te pūhiko
1. Pūhiko whakahurihuri
Ka pēhia e tēnei momo pūwero te hau hauwai mā te nekehanga hurihuri o te piston i roto i te rango. Nā ōna āhuatanga hoahoa he uaua te hanganga, ā, he maha ngā wāhanga e neke ana. I te nuinga o te wā, ki te tiakina pai, ka tata ki te 10-15 tau te roa o te ora mahi o ngā pūwero hurihuri. Hei tauira, ko ētahi o ngā pūwero hurihuri kua hoahoatia i mua, ka tata ki te 10 tau te roa o te ora mahi nā runga i ngā herenga hangarau me ngā rauemi; ka taea te whakaroa i te roa o te ora mahi o ngā pūwero hurihuri hou e whakamahi ana i ngā rauemi matatau me ngā hoahoa kua arotauhia ki te 15 tau pea.
2. Pūwhakapūngao ā-pūngao
Ka whakatereterehia, ka pēhia hoki te hau hauwai e ngā pūwero hurihuri tere-teitei. He tino māmā tōna hanganga, he iti noa ngā wāhanga e neke ana, ā, he pumau te mahi i raro i ngā tikanga mahi e tika ana. I te wā e whakamahia ana, ka taea e te roanga mahi o ngā pūwero hurihuri te eke ki te 15-20 tau. Ina koa mō ngā pūwero hurihuri kounga teitei e whakamahia ana i roto i ētahi teihana whakakī hinu hauwai nui, me te tiaki pai, ka roa ake pea te roanga mahi.
Tuarua, Ngā tikanga mahi me ngā tawhā whakahaere
1. Te pēhanga me te pāmahana
He pānga nui te pēhanga mahi me te pāmahana o ngā pūwero teihana whakakī hinu hauwai ki tōna roanga mahi. Ko te pēhanga mahi o tētahi pūwero teihana whakakī hinu hauwai noa kei waenganui i te 35-90MPa. Mena ka mahi te pūwero tata ki te rohe pēhanga teitei mō te wā roa, ka piki ake te kakahu me te ngenge o ngā wāhanga, ā, ka whakapotohia tōna roanga mahi. Hei tauira, ina mau tonu te pēhanga mahi ki te 90MPa, ka taea te whakapoto i te roanga mahi o te pūwero mā te 2-3 tau ki te whakaritea ki te mahi i te 60MPa.
Mō te pāmahana, ka puta te wera i te wā e mahi ana te pūwero, ā, ka pā te pāmahana tino tiketike ki te mahi a ngā wāhanga me te kaha o ngā rauemi. I raro i ngā āhuatanga noa, me whakahaere te pāmahana mahi o te pūwero i roto i tētahi awhe, arā, kaua e neke atu i te 80-100 ℃. Mēnā ka roa te wā e neke atu ana te pāmahana i tēnei awhe, ka pā pea he raruraru pērā i te tawhito o ngā hiri me te heke o te mahi a te hinu whakahinuhinu, ka whakaiti i te roa o te ora o te pūwero.
2. Rere me te tere kawenga
Ko te tere rere o te hauwai te mea e whakatau ana i te āhua o te kawenga o te pūwero. Mena ka roa te wā e mahi ana te pūwero i ngā tere rere teitei me ngā tere kawenga teitei (pērā i te neke atu i te 80% o te tere kawenga hoahoa), ka pāngia ngā wāhanga matua pērā i te motuka, te impeller (mō ngā pūwero centrifugal), te piston rānei (mō ngā pūwero reciprocating) i roto i te pēhanga nui, ka tere ake te kakahu o ngā wāhanga me te tawhito. Engari, ki te iti rawa te tere kawenga, ka pāngia pea te pūwero e te mahi kore pumau, ā, ka pā kino ki tōna roanga mahi. I te nuinga o te wā, he pai ake te whakahaere i te tere kawenga o te pūwero i waenga i te 60% me te 80%, ka taea ai te whakaroa i tōna roanga mahi me te whakarite i te whai huatanga.
Tuatoru, Te tiaki me te mana tiaki
1. Te tiaki i ia rā
He mea nui te tirotiro, te horoi, te whakahinuhinu, me ērā atu mahi tiaki o ngā pūwero hiko i ia wā, kia roa ake ai te ora o ā rātou mahi.
Hei tauira, mā te whakakapi i te hinu whakahinuhinu me ngā hiri i ia wā ka taea te ārai i te pakaru me te turuturu o ngā wāhanga. Ko te tikanga whānui kia whakakapia te hinu whakahinuhinu i ia 3000-5000 hāora, ā, kia whakakapia ngā hiri i ia 1-2 tau i runga i te āhua o te pakaru.
He mea nui anō hoki o te mahi tiaki o ia rā te horoi i te pūtaki me te pūtaki o te pūwhakapūngao hei ārai i ngā poke kei uru ki roto.
Ki te kore e horoia te tātari hau e tomo ana i te wā tika, ka uru te puehu me ngā poke ki roto i te pūhiko, ka nui ake te pakaru o ngā wāhanga, ā, ka whakapoto pea i te roa o te ora o te pūhiko mā te 1-2 tau.
2. Te tiaki auau me te whakakapinga wāhanga
Ko te tiaki whānui i te pūwero te mea nui hei whakarite kia mau tonu tana mahi mō te wā roa. I te nuinga o te wā, me whakatikatika te pūwero i ia 2-3 tau hei tirotiro me te whakatika i ngā wāhanga matua mō te pakaru, te waikura, me ētahi atu take; Me mahi he whakahoutanga nui i ia 5-10 tau hei whakakapi i ngā wāhanga kua pakaru rawa pērā i ngā impeller, piston, rango rango, me ētahi atu. Mā te tiaki me te whakakapinga wāhanga i te wā tika, ka taea te whakaroa i te roa o te ora o te pūwero mā te 3-5 tau, neke atu rānei.
3. Te aroturukitanga o te mahi me te whakahaere hapa
Mā te whakamahi i ngā pūnaha aroturuki matatau hei aroturuki i ngā tawhā whakahaere o te pūwero i te wā tūturu, pērā i te pēhanga, te pāmahana, te tere rere, te wiri, me ētahi atu, ka taea te kite wawe i ngā raruraru pea, ā, ka taea te mahi i ngā mahi. Hei tauira, ina kitea he wiri rerekē o te pūwero, tera pea nā ngā take pērā i te kore taurite o te impeller, te kakahu rānei o te peera. Mā te tiaki wawe ka ārai i te horapa haere o te hapa, ā, ka roa ake te ora o te pūwero.
