Tata ki te nuinga o te wāhanga mākete o ngā pūnaha hau neke atu i te 22kW te nuinga o ngā pēhanga tīwiri e whakamahia ana, me te pēhanga ingoa o te 0.7~1.0MPa. Ko te hua o tēnei ia ko te whakapai ake i tōna mahi me te pono, me te whakaiti i te tiaki me ngā utu tīmatanga.
Ahakoa rā, ko te pūwero piston mahi-rua tonu te pūwero tino whai hua. Ka whakaitihia e te āhua hurihuri o te tīwiri te whānuitanga whai huatanga teitei o te pūwero tīwiri. Nō reira, ko te āhua hurihuri pai ake, te tukatuka pai ake me te hoahoa auaha ngā āhuatanga matua o te pūwero tīwiri.
Hei tauira, ka taea e te pūwero tīwiri taraiwa-tika, tere-iti te whakarato i te pēhanga tukunga o te 0.7MPa me te rōrahi hau o te 0.13-0.14m³, arā, 90-95% o te pūwero piston mahi-rua. Mō te nuinga o ngā kaiwhakamahi, ki te kore ētahi wā ka nui te whakapaunga pūngao, nā te nui ake o te haumitanga tuatahi (te utu hoko), ko te pūwero piston mahi-rua pai ake he maha ngā wā kāore e whai hua te utu nā te roa o te wā whakahoki o te haumitanga.
Ka taea e te pūwero tīwiri e tiakina pai ana te mahi mō ngā tau 10, neke atu rānei. I taua wā anō, ka taea e tana pūnaha whakahaere me te tautuhi hapa me te tukatuka te tohu i te āputa whakawhiti hinu i runga i te pāmahana whakahaere, e whakapai ake ana hoki i te pono me te roa o te ora o te pūwero.
pupuri
Mō ngā utu tiaki, he pai ake ngā pēhi tīwiri i ngā pēhi piston. He poto ake ngā wā tiaki o ngā pēhi piston mahi-rua i ngā pēhi tīwiri. Me tiaki tonu te takirere, te mowhiti piston me ētahi atu wāhanga e mau ana i te pēhi piston.
Ko te tiaki matua o te pūwero tīwiri ko te hinu, te tātari hinu me te wehewehe hinu. I ētahi wā, he nui ngā utu e hiahiatia ana mō te whakakapinga o te hau hurihuri tīwiri me ngā taputapu tirotiro taha, engari ka taea e ēnei te mahi mō te 10 tau, neke atu rānei.
He pūmana whakahaere kei roto i te huihuinga pūwero tīwiri paerewa e hangai ana ki te tukatuka iti, ki te mana hiko rānei. Mā ēnei pūmana ka taea e te huri tīwiri te pupuri i te kawenga 100% o te wā. Ko tētahi o ngā mahi matua o te pūmana he whakarite i te rere o te hau kia taea ai e te mīhini te oma i te tino pai i raro i ngā āhuatanga kawenga katoa, kawenga wāhanga me te kore kawenga.
He maha atu anō ngā mahi whakahaere whai hua a ētahi pūmana mīhini tīwiri, pērā i te aroturukitanga mahi, te whakatūpato whakaweto me te whakamaumahara tiaki.
He pai te whakamahi i tētahi waeine kua rite ki tētahi pūwero piston mahi-rua e whakahaeretia pai ana, e tiakina ana hoki. Ka taea te whakarite me te tohatoha i tēnei momo taputapu, mā te whakamahi i ngā whakatikatika me ngā tiaki auau kia angitu ai te pūnaha hau kōpeke.
whakahinuhinu
E ai ki ngā āhuatanga whakahinuhinu rerekē, ka taea te wehewehe i ngā pūwero piston kia rua ngā momo: he mea whakahinuhinu, he mea kore-whakahinuhinu. I roto i te waeine kua whakahinuhinuhia, ka whakaurua te hinu whakahinuhinu ki roto i te rango kōpeketanga hei whakaiti i te waku i waenga i te rango me te mowhiti piston. I raro i ngā āhuatanga noa, ka taea e te mowhiti piston kua whakahinuhinuhia pai te roa mō ētahi tau, ā, mā te whakamahi i ngā rauemi matatau ka taea te whakaroa i te roanga o te ora o te mowhiti piston i roto i te waeine momo-maroke ki te neke atu i te 8000h.
He mea tika kia whakaarohia te utu i waenga i ngā miihini piston kua whakahinuhinuhia me ngā miihini kāore i whakahinuhinuhia. I ētahi wā, me whakamahi te hau kōpeke, te hau rānei, kāore he hinu. Ko te haumitanga tuatahi o tētahi waeine kāore i whakahinuhinuhia he 10-15% teitei ake, ā, he iti noa te rerekētanga i waenga i te whakapaunga pūngao me te whai huatanga. Ko te rerekētanga nui kei roto i te tiaki e hiahiatia ana mō ngā momo waeine e rua. Te utu, ko te utu tiaki o tētahi waeine kāore i whakahinuhinuhia e whā ngā wā, neke atu rānei i te utu o tētahi waeine kua whakahinuhinuhia.
Ko te kaha kore taurite me te taumaha o te pūwero piston ngā mea matua e pā ana ki te utu tāutanga. I te nuinga o te wā, me whai turanga taumaha me te turanga matotoru te waeine piston. Ko te tikanga, ka whakaratohia e te kaihanga pūwero ngā raraunga e tika ana hei hanga i te turanga.
Ahakoa he nui ake te utu haumitanga tuatahi me te tāutanga o te pūwero piston i tērā o te pūwero tīwiri, ko te roanga o te ora o te pūwero piston i raro i te tiaki pai ka 2 ki te 5 ngā wā roa atu i tērā o te pūwero tīwiri.
Mō ngā tekau tau, kua noho te pūwero piston hei mīhini mahi taumaha pono. Nā te whanaketanga o te hangarau, me te whakarato i te hau kounga teitei, kua tino heke te utu tiaki o ngā pūwero piston. I roto i ngā waeine me te pēhanga ingoa o te 0.7～1.0MPa, ahakoa he hau kōpeke, he hau kē atu rānei, ko te pūwero piston tonu te whiringa pai rawa atu.
