I te kaha haere o te hiahia o te ao mō ngā otinga ahumahi pumau, kei te tahuri ngā kaihanga ki te whakatipuranga houngā pūnaha pēhi hau tīwirihei whakatika i te pikinga o ngā utu whakahaere me ngā āwangawanga taiao. E whakaatu ana ngā raraunga mākete hou kua noho hei mea nui ngā pēhi tīwiri werohanga-hinu puta noa i ngā umanga taumaha, ngā mahi whakarewa, me ngā whare tango kohuke, e tuku ana i te pono me te penapena pūngao onge.
He aha te mea e hira ai ngā pūwero hau tīwiri mō te ahumahi taumaha?
P: He aha te rerekētanga o ngā pūwhakakoi tīwiri me ngā pūwhakakoi tauutuutu i roto i ngā mahi taumaha?
A: Kāore i rite ki ngā pūwero hurihuri me ngā whiu piston wā-poto, ka mahi ngā pūwero hau tīwiri mā roto i ngā rotor hurihuri takirua—he hoahoa patent e tuku ana i te hau kōpeke tonu, kāore he pātītī. Ka whakaputa tēnei tikanga hou i ngā taumata wiri iti ake, ka whakaiti i te putanga haruru ki te 75-80 tekipere (ki te 90+ dB mō ngā waeine hurihuri), ā, he iti noa te tiaki auau e hiahiatia ana. Mō ngā taiao uaua pēnei i ngā tipu whakarewa me ngā mahi keri tuwhera, ka puta he roa ake te roa o te ora o ngā taputapu, he iti ake te wā kore mahi, me te iti ake o te utu katoa o te mana whakahaere.
Ko te momo pūwero tīwiri i werohia ki te hinu—te paerewa ahumahi—e whakamahi ana i te hinu kohuke motuhake mō te whakamatao, te hiri, me te whakahinuhinu i roto i te rūma pēhanga. Mā tēnei hoahoa ka taea te whakanui ake i ngā ōwehenga pēhanga (tae atu ki te 10:1) me te pupuri tonu i te pumau o te wera, he mea nui mō ngā tono ahumahi taumaha e mahi tonu ana.
Te Whanuitanga o te Mākete i roto i te Keri, te Whakarewa, me te Hanganga Whakarewa
E whakaū ana ngā kaiwhakaatu ahumahi kua piki ake te whakamahinga o te pēhi hau tīwiri mā te 28% i ia tau i roto i ngā rāngai ahumahi taumaha, inā koa i roto i:
• Ngā Mahi Keri: Te whakakaha i ngā taputapu keri hau, ngā mīhini kuru kōhatu, me ngā pūnaha hauhautanga i roto i ngā whare o raro whenua
• Te Whakarewatanga Whakarewa: Te tuku hau kōpeke mō ngā oumu pupuhi, ngā tukanga whakamahana, me ngā pūnaha whakahaere rauemi
• Te Hanga Taputapu Taumaha: Te taraiwa i ngā taputapu hau, ngā raina huihuinga aunoa, me te whakamātautau i ngā oko pēhanga
• Te Whai Hua o te Pūngao: Te Painga e Hurihuri Ana i te Kēmu
P: He aha ngā whakapainga whai hua e whakamārama ana i te haumitanga pūtea ki ngā pūnaha kōpeke tīwiri hou?
A: E whakaatu ana ngā raraunga o nāianei ka whakaitihia te whakapaunga pūngao e ngā pūwero tīwiri e mau ana i te puku auau taurangi (VFD) mā te 25-35% ki te whakataurite ki ngā tauira tere-pūmau e mahi ana i te kawenga wāhanga—he āhuatanga noa i roto i ngā huringa whakaputa ahumahi.
Whakaarohia tēnei tauira mahi: Ko tētahi mahi whakarewa nui e whakahaere ana i ngā hāora mahi ā-tau e 8,000, e 150-200 kW te mana hiko e pau ana mā roto i ngā pūwero whakawhiti. Mā te whakahou ake ki tētahi wae tīwiri e āhei ana ki te VFD, ka tutuki i te whare taua te putanga ōrite me te paunga tata ki te 110-130 kW—arā, ko te 90,000-200,000 USD te penapena hiko ā-tau, i runga i ngā utu hiko ā-rohe.
Hei tāpiri, ko te pai o te whai huatanga o te whakamatao o ngā pūnaha weronga hinu hou ka whakaiti i te moumou pūngao mā te marara wera, ā, ko te whakamatao muri me te wehewehe makuku kua whakauruhia ka whakaiti i ngā hekenga pehanga me te waikura o ngā taputapu.
Te Whakaurunga me te Whakatutukitanga o ngā Ipu Pēhanga
P: He aha te mea nui ai te tiwhikete oko pēhanga mō ngā pūnaha kōpeke tīwiri taumata ahumahi?
A: Ka whakaputahia e ngā pūwero tīwiri kaha-teitei (pēhanga mahi noa: 8-13 pae, 116-189 psi rānei) ngā whakaritenga rokiroki hau pēhanga. Me tutuki ngā oko pēhanga katoa—tae atu ki ngā tāke rokiroki me ngā tāke kaiwhiwhi—ki ngā paerewa o te ao:
• Tiwhikete CE (Uniana o Ūropi)
• Waehere ASME (Te Hononga o Amerika me Kānata)
• PED Directive 2014/68/EU (European Pressure Equipment Directive)
Mā ēnei ture ka whakarite i te pumau o te hanganga, te haumaru pakaru, me te tiaki i ngā kaimahi. Ka whakauruhia e ngā kaihanga pūwero tīwiri hou ngā tāke kaiwhiwhi whaimana me ngā pūnaha waikeri aunoa, ngā takirere whakamāmā pēhanga, me ngā tikanga whakahaere makuku—ka whakakorea te mōrearea o te kohikohi wai e waikura ai ngā whatunga paipa me te kino i ngā taputapu hau o raro.
Te Mahi Tuturu o te Ao i roto i te Tango Kohuke
P: He pēhea te mahi a ngā pūwero tīwiri i roto i ngā taiao keri uaua me te puehu nui me ngā piki me ngā heke o te pāmahana?
A: Kei roto i ngā pūwero tīwiri ahumahi hou ngā pūnaha tātari hau maha-wāhanga e kaha ana ki te whakahaere i ngā kawenga matūriki neke atu i te 5,000 mg/m³—he nui ake i ngā taiao wheketere noa. Mā ngā tātari me ngā wehewehe whakaurunga whakarei ake ka tiakina ngā huānga pēhanga mai i ngā matūriki whakakoi e kitea ana i roto i te keri tuwhera.
He mea nui anō hoki te whakahaere wera. Ka pupuri ngā pūnaha tīwiri whakamatao-hinu i te pāmahana tukunga i roto i te 60-75°C ahakoa te roa o te mahi i roto i ngā āhuarangi taiao teitei (tae atu ki te 45°C te pāmahana o waho), ka tiakina te matotoru o te hinu, ā, ka roa ake ngā wā mahi ki te 2,000+ hāora i waenga i ngā mahi tiaki o ia rā.
