I roto i te tukanga hangarua pepa para o te umanga hanga pepa, ko te hydrapulper te taputapu matua. Ko tāna mahi matua ko te wawahi i ngā pepa para, ngā papa penupenu me ētahi atu rauemi mata hei penupenu, hei whakatakoto i te turanga mō ngā tukanga hanga pepa e whai ake nei.
1. Te Whakarōpūtanga me te Hanganga Hanganga
(1) Te Whakarōpūtanga mā te Kukū
- Pūwero waipara iti te ōritetanga: He iti te ōritetanga o te mahi, ā, ko tōna hanganga he mea hanga nui mai i ngā wāhanga pēnei i ngā rotor, ngā awaawa, ngā maripi raro, me ngā pereti mata. He momo rotor pēnei i ngā rotor Voith paerewa me ngā rotor Voith penapena-pūngao. Ka taea e te momo penapena-pūngao te penapena i te 20% ki te 30% o te pūngao ki te whakataurite ki te momo paerewa, ā, he pai ake te hoahoa o te mata ki te tohanga o te penupenu. He porotaka te nuinga o te awaawa, ā, ko ētahi e whakamahi ana i ngā awaawa āhua-D auaha. Ka meinga e te awaawa āhua-D te rere o te penupenu kia pōrearea, ka taea e te ōritetanga o te penupenu te eke ki te 4% ki te 6%, he nui ake te kaha whakaputa i te 30% i te momo awaawa porowhita, ā, he iti te horahanga o te papa, he iti te hiko me ngā utu haumi. Ko te nuinga o te maripi raro ka taea te wetewete, he mea hanga ki te maitai kaha-teitei, ā, kua whakakikoruatia te mata o te mata ki ngā rauemi ātete-kakahu pēnei i te maitai NiCr. He iti te whānui o ngā kōhao mata o te pereti mata, ko te tikanga he 10-14mm. Mena ka whakamahia hei wawahi i ngā papa penupenu arumoni, he iti ake ngā kōhao mata, mai i te 8-12mm, ā, he mea nui tēnei hei wehe tuatahi i ngā paru nunui.
- Pūwero wai pūmau-teitei: Ko te pūmautanga mahi he 10% – 15% neke atu rānei. Hei tauira, ka taea e te rotor pūmau-teitei te whakanui ake i te pūmautanga pakaru penupenu ki te 18%. He rotor tāpine, he rotor pūmau-teitei, me ētahi atu. Ka taea e te rotor tāpine te eke ki te pūmautanga pakaru penupenu ki te 10%. Mā te rotor pūmau-teitei ka whakanui ake i te horahanga pa ki te penupenu, ā, ka taea te pakaru mā te whakamahi i te mahi kutikuti i waenga i ngā muka. He rite te hanganga o te awa ki te hanganga o te iti-pūmau, ā, ka āta tangohia te awa āhua-D, ā, he maha ngā wā ka mutu te mahi. He nui ake te whānui o ngā kōhao mata o te pereti mata, ko te tikanga he 12-18mm, ā, ko te horahanga tuwhera he 1.8-2 ngā wā i te wāhanga putanga penupenu pai.
(2) Te Whakarōpūtanga mā te Hanganga me te Aratau Mahi
- E ai ki te hanganga, ka taea te wehewehe ki ngā momo whakapae me ngā momo poutū; e ai ki te momo mahi, ka taea te wehewehe ki ngā momo tonu me ngā momo wā poto. Ka taea e te hydrapulper poutū tonu te tango tonu i ngā poke, me te whakamahinga nui o ngā taputapu, te kaha whakaputa nui me te haumi iti; he pumau te tohu pakaru o te hydrapulper poutū wā poto, engari he nui te whakapaunga pūngao ā-wae, ā, ka pāngia tōna kaha whakaputa e te wā kore-pakaru; he iti ake te pa o te hydrapulper whakapae ki ngā poke taumaha me te iti ake o te kakahu, engari he iti noa te kaha mahi.
2. Te Kaupapa Mahi me te Mahi
Mā te mīhini hydrapulper ka panaia te penupenu kia puta ai te kaha o te aueue me te kaha kutikuti miihini mā te hurihanga tere o te rotor, kia haehaea ai ngā rauemi mata pērā i te pepa para, kia marara ai ki roto i te penupenu. I taua wā anō, mā te āwhina o ngā wāhanga pērā i ngā pereti mata me ngā taputapu 绞绳 (ngā rīra taura), ka tutuki te wehenga tuatahi o te penupenu me ngā poke, ka hangaia he tikanga mō ngā tukanga purenga me te tirotiro i muri mai. Ko te mīhini hydrapulper iti-pūmau e aro nui ana ki te pakaru miihini me te tango poke tuatahi, ko te mīhini hydrapulper teitei-pūmau ka whakaoti pai i te pakaru i raro i te pūmautanga teitei mā te whakaoho waipēhi kaha me te waku i waenga i ngā muka. He tino pai mō ngā raina whakaputa e hiahia ana kia tangohia te waituhi, ka māmā ake te wehe i te waituhi mai i ngā muka, ā, he pai ake te tango i ngā matū rewa wera i ngā mīhini hydrapulper iti-pūmau noa.
3. Te Whakamahinga me te Hiranga
He whānuitia te whakamahinga o ngā hydrapulpers i roto i ngā raina whakaputa para pepa, ā, he taputapu matua ēnei mō te whakamahi i ngā rauemi para pepa. E kore e taea e tā rātou mahi whai hua te whakapai ake i te tere whakamahinga o ngā pepa para, te whakaiti i te utu o ngā rauemi mata hanga pepa, engari ka whakaiti hoki i te whakawhirinaki ki te rakau mata, e hangai ana ki te ia whanaketanga o te tiaki pūngao me te tiaki taiao. Ka taea te whiriwhiri ngāwari i ngā momo hydrapulpers kia rite ki ngā hiahia whakaputa. Hei tauira, ka taea te whiriwhiri i te momo poutū tonu mō te tukatuka i ngā pepa para he nui ngā poke, ā, ka taea te whiriwhiri i te momo tino ōrite mō te hiahia ki te tere pakaru me te pānga tango waituhi, kia pai ai te mahi i roto i ngā āhuatanga whakaputa rerekē me te whakatairanga i te whanaketanga pumau o te umanga hanga pepa.
