Ka taea te whai i te tauira rere o te pūwero piston iti kua whakamataohia e te hau ki te tīmatanga o te rautau 19. He whānuitia te whakamahinga o ēnei i roto i ngā taputapu maha, ka taea e te pēhanga teitei te eke ki te 1.2MPa. Ka taea te whakarerekē i ngā waeine hau whakamatao o ngā rahi rerekē ki te taiao koraha.
Ko te pūwero piston iti tino noa ko te mahi-kotahi. Ka taea e te pāmahana putanga te eke ki te 240°C, ā, ko te nuinga o te haruru mahi o te waeine neke atu i te 80dBA.
Mō ngā waeine iti-mana, nā te mea he 40-60% te iti iho o te utu haumitanga tuatahi i tō ngā pūwhakakoi tīwiri, he nui ake te uara whakamahi o ngā pūwhakakoi piston. Me whai whakaaro anō hoki ki ētahi atu taputapu āwhina, pērā i te whakamatao tuarua, te tīmatanga me te pana whakaweto, me whakauru ēnei utu ki te utu katoa.
Ka taea e ngā pūwero piston iti te whakarato i te hau kōpeke kounga teitei mō ngā taputapu maha i roto i te wā roa. Ko te hoahoa māmā, te whānuitanga o te mahi me te pono teitei ngā kaha nui o ēnei.
Ahakoa he nui ake te utu o te haumitanga tuatahi o ngā pūwhakakoi tīwiri i ngā pūwhakakoi piston, kei te piki haere te rongonui o ēnei i roto i te awhe mana o te 7.4-22kW. Ko tētahi take he mea tākai ngā wae tīwiri hei kōwae. I te nuinga o te wā, ka tākaihia te kōwae wae tīwiri paerewa me te tīmatanga, te whakamatao muri, me te kaiwhakahaere pūwhakakoi me ngā āheinga aroturuki kaha.
Ka taea hoki te whakamahi i ngā pūwero tīwiri i roto i te awhe mana iti ake, mai i te 3.7 ki te 22kW. I raro i te āhua mana kotahi, ko tētahi painga i runga i ngā pūwero piston ko te iti o te pāmahana o te putanga hau. Kua hangaia te pūwero tīwiri kia mahi i raro i te huringa kawenga 100%, me te hinu whakahinuhinu iti me te whakarato hau kōpeke kounga teitei.
Tāuta
Me whai tāke penapena hau ngā pūwero piston iti. Ka whakamahia te tāke penapena hau hei penapena hau pēhi me te whakaiti i te wā mahi kawenga o te pūwero. Ko ētahi pūwero piston iti e mahi ana i roto i te 66% pea o te wā huringa mahi (kawenga).
He mea tino nui te roa o te ora o tētahi mīhini piston me te nui o te tāke penehīni. Ahakoa te rahi o te tāke penehīni, te hanganga rānei o te compressor me te tāke penehīni, he māmā noa iho te tāutanga o tētahi compressor piston iti. Nā te kore taurite o ngā kaha, me whakau tetahi compressor piston ki te whenua.
Ko te nuinga o ngā waeine mīhini tīwiri he mea hanga kia taea te neke motuhake, ā, ka taea hoki te whakatakoto i tō rātou turanga tāutanga ki runga ake i te tāke penehīni. Kāore he pao i roto i te tukunga o te pūwhakakoi tīwiri. Heoi anō, he tino whai hua te pūnaha tae atu ki te tāke rokiroki hau mō te whakahokinga maeneene o te tohu hau ki te kaiwhakahaere pūwhakakoi me te mahi pumau o te pūnaha.
Ka taea e ngā pūwero tīwiri iti te whakarato i te pouaka katoa ki ngā kaiwhakamahi, ka taea te whakamahi i roto i ngā pūnaha hau kōpeke e hiahia ana ki te rōrahi hau pumau. Ko te taumata haruru mahi o te nuinga o ngā waeine tīwiri kua kati he iti iho i te 80dBA. Ka taea te tāuta ngāwari i te pūwero tīwiri kua takaihia ki runga i te papa, ā, he taputapu hononga kotahi-ira anake te nuinga e whakamahia ana hei hono i te hiko me te hau.
He mea nui te whiriwhiri i te wāhi tāutanga tika mō te pono me te roa o te ora o te mīhini whakamātao hau. Ko te rere pai o te hau i roto i te tinana o te mīhini whakamātao he mea nui mō te mahi pai me te roa o te ora o te mīhini.
I te nuinga o te wā, he pai ake te kounga o te hau kōpeke o ngā kōpeke tīwiri. Ahakoa he wae tīwiri kua pania ki te hinu, ka taea e te wehewehe hinu-hau teitei te whakaiti i te ihirangi hinu e tukuna ana ki te pūnaha hau kōpeke ki te 5ppm. I taua wā anō, ka taea e te pāmahana putanga iti o te mīhini tīwiri te whakapai ake i te kounga o te hau kōpeke. Ko te pāmahana putanga o te nuinga o ngā wae tīwiri he 50°C noa iho te teitei ake i te pāmahana taiao.
