E paingia ana te mīhini hiri kiriata aunoa maha-mahi e ngā umanga tukatuka kai iti me te rahi-rahi nā tōna kaha ki te hiri, te mahi pumau, me te pānga hiri pai. He whānuitia hoki te whakamahinga i roto i te hanga putea takai ngohengohe. Mēnā he raruraru ki te kaha hiri o ngā taha, waenganui, raro rānei i te wā e hanga ana i te putea kiriata kirihou, ka taea te whakamahi i tēnei mīhini mō te hiri anō kia tutuki ai ngā whakaritenga o te kounga hiri wera.
Heoi, i muri i te whakamahinga roa, inā koa i raro i ngā āhuatanga mahi, i te taumaha rawa rānei, ka pāngia te mīhini e ētahi hapa hiko me ngā hapa miihini. Kei roto i ēnei: te hiri ngoikore, te mahi ā-wā o te mīhini, te pupuhi o te fuse i te tīmatanga, te tangi "ngūngū" i te wā e mahi ana, te pāmahana kore e taea te whakahaere, te whakarerekētanga me te piko o ngā putea kua oti i te wāhi hiri, me te putanga mai o ngā mirumiru, ngā tohu koretake rānei i te tohu o te mata hiri. I runga i ngā wheako whakamahinga mahi, ka tātarihia e tēnei tuhinga ngā take o ētahi hapa noa, ka whakaarohia ngā otinga e rite ana, ā, ka matapakihia te tiaki o te mīhini hiri, me te tumanako ka āwhina i ngā umanga me ngā tāngata takitahi e whakamahi ana i te mīhini.
1. Hiritanga Kino
Ko te hiri koretake tētahi o ngā hapa noa o te mīhini hiri. E toru ngā tikanga o te hiri koretake:
- Kāore e taea te hiri i te putea tākai i te pūwāhi hiri.
- Ahakoa kua hiritia te waha o te putea i raro i te pēhanga o te mata hiri, ka pakaru anō mā te pēhi, te tihore rānei.
- I te wā e whakahaerehia ana he whakamātautau tihore i te pūwāhi hiri, ka hiritia te haurua o te putea, ko te haurua kua wehea. Kāore anō kia tino tika te kounga hiri o tētahi putea tākai pēnei nā te mea ka ngawari te turuturu o ngā mea i roto i te wā e rongoa ana, e kawe ana hoki ina pēhia. He maha ngā wā ka puta tēnei āhuatanga ina he OPP, he PE pupuhi rānei te rauemi arai whakakotahi.
Ko ngā tino take o te momo tuatahi o te hapa ko:
- Kāore i te rawaka te pāmahana hiri wera. I raro i ngā āhuatanga noa, mō ngā putea hiato me te OPP hei rauemi whakarara me te matotoru katoa o te 80-90μm, me eke te pāmahana hiri wera ki te 170-180℃. Mō ngā putea hiato me te PE hei rauemi whakarara me te matotoru katoa o te 85-100μm, me whakahaere te pāmahana ki te 180-200℃. I te mea ka piki ake te matotoru katoa o te putea, me whakanui ake te pāmahana hiri wera.
- Tere rawa te tere o te hiri wera. Ko te kore e taea te hiri i te putea e pā ana ki te tere o te mīhini hiri. Ki te tere rawa te tere, kāore e ranea te wā o te pūwāhi hiri ki te whakamahana i mua i te kawe ki te mīhini whakamatao e te roera kukume mō te maimoatanga whakamatao, ā, he mea noa, kāore e taea te whakatutuki i ngā whakaritenga kounga hiri wera.
- Te pēhanga kore e tika ana o te wira rapa o te mīhini whakamatao. Kotahi te wira rapa o te mīhini whakamatao kei ngā taha o runga me raro, ā, me taurite te pēhanga i waenganui i a rāua. I te wā e whakarerekē ana i te pēhanga, me whakau noa te puna.
- Ngā take kounga o te kiriata hiri-wera. Ko te kore e taea te hiri i te putea e pā ana ki te kounga o te kiriata hiri-wera. Mena he koretake te maimoatanga korona o te rauemi arai hiato, ā, kāore i te whai hua, ā, kei te wāhi hiri, e kore rawa e taea te hiri i te putea. He onge tēnei āhuatanga, engari ina puta, ka whakakorea te hua. Nō reira, i roto i te umanga tākai tā tae, ka tirotirohia e te tukanga o raro te tukanga o runga. Kia kitea ngā raruraru kounga, me tātari me te whakatau i ngā take i te wā tika. Mena he makuku, he paru rānei kei te wāhi hiri, ka puta hoki he hiri ngoikore. Hei whakarāpopototanga, hei whakatau i te momo tuatahi o te raruraru hiri ngoikore, ka taea te whakanui ake i te pāmahana hiri-wera, ka taea te whakaiti i te tere hiri-wera, ā, ka taea te whakanui ake i te pēhanga o te wira rapa mīhini whakamatao i te wā kotahi.
Ko ngā take matua o te momo tuarua o te hapa hiri ngoikore ko:
- Kāore i te rawaka te pāmahana hiri-wera. Ka taea te whakatau i te raruraru mā te whakanui ake i te pāmahana hiri-wera.
- Kāore te mata o te mata hiri-wera i te papatahi. Kua wehea te mata hiri-wera ki ngā wāhanga o runga me raro, ā, he mea tāuta he thermocouple ki roto hei rongo i te whakawhiti pāmahana. E toru ngā tīwiri i runga i te mata hiri-wera, ko te tīwiri waenga hei tautoko, hei whakapakari i te mata, ā, ko ngā tīwiri e rua e mau ana ki ngā puna pēhanga me ngā horoi, e whakamahia ana hei whakatika i te pēhanga o te mata hiri-wera. E rua ngā puna o ia mata o runga me raro. Ko te take matua mō te kore ōrite o te mata o te mata hiri-wera ko te kore o te tīwiri waenga e tāuta whakapaetia ana, te kore ōrite rānei o te pēhanga o te puna pēhanga o te mata hiri-wera o runga.
- Ko te otinga he whakatika anō i te tūranga o te tīwiri waenga kia whakapae. Mena kāore i te taurite ngā mata hiri wera o runga me raro, ka taea tēnei mā te whakarerekē i te puna pēhanga ki te taumata taurite. Ina panaia te puna ki waho, ka taka te mata hiri wera ki raro. Ina whakakīia te puna o te mata o raro ki runga, ka neke ake te mata hiri wera.
- Te pēhanga kore taurite o te wira rapa o te mīhini whakamatao. Ka puta anō hoki tēnei momo hapa hiri ngoikore i te pēhanga kore taurite o te wira rapa o te mīhini whakamatao, ā, he rite te otinga ki te āhuatanga tuatahi.
Ko ngā take matua o te tuatoru o ngā momo hapa hiri ngoikore ko:
- Kāore i te ōrite te pēhanga o te mata hiri-wera, o te mata whakamatao rānei. He rite tonu te whakarerekētanga o te mata hiri-wera me te mata whakamatao.
- Kāore te mata o te mata hiri-wera i te papatahi. Tirohia te otinga e tika ana mō te momo tuarua o te hapa hiri ngoikore.
2. Te Pupuhitanga o te Fiusi
Ko te motuka matua o te mīhini hiri kiriata kirihou ko te motuka AC tuatahi o te whare me te pouaka taputapu kutukutu whakauru konumohe parakore, e taraiwa ana i te pouaka miihini me te tuku taputapu o ia waahanga. I ētahi wā, ina tīmata te mīhini hiri, ka puta he tangi "kiki", kāore e taea te mahi noa, ā, ka pupuhi te fiusi i runga i te waea ora.
Hei whakatau i tēnei raruraru, tirohia tuatahi mēnā he pai te pūnaha hiko, kātahi ka tapahia te pūnaha hiko, whakamahia te awhe ātete hei ine mēnā kua pakaru te pana, ā, tirohia mārire mēnā kua poto te ara iahiko me te motuka. I te nuinga o te wā, ina poto te ara iahiko o te motuka, kua wera te takai, kua whati rānei te waea, ka pupuhi te fiusi ina tīmata te mīhini hiri. Ko tētahi atu take mō tēnei hapa he iti rawa te whakatakotoranga o te fiusi. Mā te whakanui ake i tōna whakatakotoranga ka taea te whakatau i te raruraru.
3. Te tangi "Squeaking" i te wā e mahi ana
Ka puta tēnei hapa i te wā e whakahaerehia ana te mīhini hiri. He maha ngā wā ka puta ohorere te tangi "ngūngū", ā, muri iho ka puta te tere hiri kore taurite, ka puta he tauira kino i te tohu hiri o te putea tākai, ka pā ki te kounga o te āhua o te hua. I ētahi wā ka taea e ia te mahi noa, engari he uaua ki te matapae.
Ko te nuinga o tēnei āhuatanga he kino ā-mīhini, he kino rānei te kakahu, me te koretake o te hinu whakahinuhinu. Ko te otinga he whakaranu i te momo hinu miihini kotahi me te hinu whakahinuhinu, ka tāpirihia ki te pouaka miihini, kātahi ka whakakīia ngā tīwiri hei whakaora. I muri i te tīmatanga o te mīhini, ka ngaro te tangi "kiki", ā, ka hoki te hiri ki te āhua noa.
Hei tāpiritanga, ki te mea he wetekina te hononga o te whitiki pāmahana-teitei, he tino tawhito, ā, kāore i te ma me te paru i runga i te mata, ā, kāore e taurite ki te wira kukume i te wā e mahi ana, ka puta he tangi "ngūngū". Ko te otinga ko te whakakapi i te whitiki pāmahana-teitei ki te whakatakotoranga ōrite. He pūkenga motuhake ki te whakakapi i te whitiki pāmahana-teitei. Tuatahi, pēhia te puna wira pēhanga ki te ringa, kātahi ka whakanoho i tetahi pito o te whitiki pāmahana-teitei ki runga i te wira rapa, ka pupuri i tetahi pito ki tetahi atu wira rapa ki te ringa. Whakatakotoria te kaiwhakahaere tere ki te tere iti. Kia tīmata, me te whakawhirinaki ki te korekore o te nekehanga, ka tāuta aunoa te whitiki pāmahana-teitei.
I ētahi wā ka puta te tangi "ngūngū" mai i te motuka DC shunt. Tērā pea nā te korenga o te hinu i roto i ngā peera o te motuka. Mena koinei te āhua, me wetewete te motuka, ā, me pania ki te hinu, ā, ka ngaro te tangi.
4. Te Ngaronga o te Mana Whakahaere Pāmahana Hiri
Ko te āhuatanga o tēnei hapa ko te hē o te ine pāmahana, te kore e taea te whakahaere i te pāmahana, te pāmahana hiri-wera kāore i te pumau, ā, kua wera, kua kore rānei e hiritia te pūwāhi hiri, me te hiri kua hē, kāore hoki e ātaahua. Ko te tino take o tēnei hapa ko te pakaru o te inemahana me whakatika. Hei tāpiri, tera pea ka pakaru te takirua wera, ā, kāore e taea te tuku i te pāmahana i kitea ki te inemahana. Mā te whakakapi ki te momo me te whakatakotoranga kotahi o te takirua wera ka taea te whakatau i te raruraru.
Mai i te taha miihini, ko te take he kore taurite te pēhanga hiri-wera. Mēnā ka whakatikatikaina te puna pēhanga o te mata hiri-wera kia ōrite te pēhanga, ka taea te whakatau i te raruraru. I taua wā anō, me noho ma te mata e pā ana ki te mata hiri-wera, kia kore hoki he paru.
Ko tētahi atu take he kore pai te kounga hiri-wera o te rauemi hiato, ā, ka rerekē te tauwehenga hiri-wera, ka kore e ōrite te pāmahana ka taea e ia te tu atu.
5. Te Mahi Wā-poto o te Mīhini Hiri
Kua tūtaki mātou ki te hapa o te mahi ā-wā me te tere koretake o te mīhini hiri i te wā e hanga ana. Whai muri i te wetewete i te panera i muri o te mīhini hiri, i kitea kua wetekina, kua motumotu hoki te hononga i waenga i te pou motuka me te pouaka miihini. Mā te whakau anō i ngā tīwiri kia pai ai te uru ka whakatauhia te raruraru. Hei tāpiri, ka mahi te motuka matua mā te pā ki ngā paraihe waro. Mena kua tino tawhito ngā paraihe waro, kaua e pā katoa ki ngā mowhiti paheke, he iti rānei te waku, ka mahi ā-wā anō hoki te mīhini hiri. Mā te whakakapi i ngā paraihe waro ki ngā momo paraihe hou ka whakatauhia te raruraru.
6. Ngā Mirumiru me ngā Tohu Tauritekore i te Wāhi Hiri
He tino noa hoki tēnei hapa. Ahakoa kāore e turuturu te takai, ka pā ki te ataahua o te takai, ā, ka kino hoki te ahua o te hua.
Ko ngā tino take o tēnei hapa ko ēnei e whai ake nei:
- I muri i te whakamahinga roa o ngā taputapu, ka piri te puehu me ngā kongakonga kirihou me ētahi atu paru ki te whitiki pāmahana-teitei, ka kore e ōrite te whitiki, ka kore e taurite. Ka hua ake tēnei i te wera kore ōrite i te pūwāhi hiri. I muri i te pēhitanga o te wira perehi whakamatao, ka puta he mirumiru. Mā te horoi, te whakakapi rānei i te whitiki pāmahana-teitei ka taea te whakakore i te hapa. Ko te whānui o te whitiki pāmahana-teitei he 1.5 cm te nuinga, ā, he 22μm te matotoru. Mena he tino kore e taea te horoi i te paru, me para.
- He tohu kōpiko me te kōpiko kei runga i te wira rapa o te mīhini whakamatao, ā, ka kitea tika ēnei tohu ki runga i te takai, ka puta he maha ngā tohu mārama i te wāhi hiri. Hei whakarite i te āhua ataahua o te putea takai, he pai ake te whakakapi i te wira rapa o te mīhini whakamatao.
7. Ngā Take hei Whakaaroaro mā te Tiaki Taputapu
- Me whakanoho te mīhini hiri ki tētahi wāhi maroke, hauhautanga hoki, me pupuri tonu te pāmahana rūma ki te 25℃.
- I muri i ia 48 hāora o te mahi a te mīhini hiri, me tāpiri he hinu miihini 6# ki ia wāhanga e neke ana, ko te nuinga kei ngā taputapu, ngā whāriki, me te pouaka miihini.
- Me tango puehu i ia wā kia ma ai te mīhini katoa. Ina kore e whakamahia, he pai ake te momotu i te pūtake hiko ka hipoki ki te taupoki.
- Ki te roa rawa te wā e oma ana, me tahuri te pā hau whakamatao i mua i te whakaweto i te mīhini. Taria kia heke te pāmahana i mua i te whakaweto i te mīhini. Nā te mea ki te whakaweto koe i te mīhini me te kore e whakamatao, ka tino ngāwari te pakaru o te whitiki pāmahana teitei.
- Me horoi tonu te whitiki pāmahana-tiketike i te paru kia pai ai te hiri.
- Me whakakapi ngā wāhanga kua tino tawhito i roto i te wā tika kia roa ake ai te ora o te mīhini katoa.
