Kupu Whakataki
I roto i te aunoatanga ahumahi, he wāhanga nui ngā takirere solenoid mō te whakahaere i te rere o te wai i roto i ngā tono mai i te hanga me te tukatuka matū ki te pūngao me te hauora. Ahakoa he maha ngā wā e aro nui ana ki te hoahoa takirere me te whai huatanga hikohiko, ko te kōwhiringa o ngā rauemi hiri he mea nui tonu mō te mahi roa. Ka ārai ngā hiri i te turuturu o roto me waho, ka pupuri i te pumau o te pēhanga, ā, ka ātete ki te pirau mai i ngā pāpāho, te pāmahana, me ngā huringa mahi. Mā te whakatau hē i tō rātou hototahi ki ngā āhuatanga mahi ka arahi pea ki te pakaru wawe, ngā mōrearea haumaru, me te wā whakatā kore utu. Ka tirohia e tēnei tuhinga e toru ngā polymer hiri e whakamahia whānuitia ana—NBR, FKM, me te EPDM—ā, e whakarato ana i tētahi anga hanganga mō te whakataurite i ngā āhuatanga o ngā rauemi ki ngā whakaritenga tono.
1. Te Tūranga o ngā Hiri i roto i te Pono o te Takirere Solenoid
He maha ngā mahi nui a ngā hiri i roto i ngā takirere solenoid:
Te Ārai i te Tūtaki: Mā te hanga arai pakari i waenga i ngā wāhanga neke me ngā tinana takirere, ka whakarite ngā hiri kia kore rawa he tūtaki i roto i ngā tono pūmau me ngā tono hihiri.
Ātete Matū: Me ātete ki ngā mea kaha, tae atu ki ngā hinu, ngā waikawa, ngā whakarewa, te mamaoa rānei, me te kore e pupuhi, e ngatata, e pirau rānei.
Te Urutau ki te Pāmahana: Ka mau tonu te ngāwari o ngā hiri ahakoa ngā pāmahana tino rerekē, mai i ngā āhuatanga cryogenic ki ngā taiao mamaoa pāmahana teitei.
Te Pakari o te Mīhini: Ka tu atu i te pēhanga me te waku auau mai i te nekehanga o te takirere, ā, ka ātete ki te pakaru me te whakaputanga i roto i ngā miriona huringa.
Mā te whiriwhiri rauemi hē ka arahi pea ki te whakapakeketanga o te hiri, te whakapūtanga, te waikura matū rānei—ngā tino take noa o te rahunga o te takirere.
2. Ngā Rauemi Hiri Matua: Ngā Āhuatanga me ngā Whakamahinga
2.1 NBR (Rapa Nitrile Butadiene)
Ngā Kaha Matua: He ātete tino pai ki ngā hinu, ngā wahie, me ngā hinu whakangao i ahu mai i te kohuke, ā, he otinga utu-pai mō ngā pūnaha waipēhi me te hau. He pai hoki te ātete ki te pakū me te kaha kume.
Ngā Here: He ngoikore ki te ozone, te pānga o te UV, me ngā whakarewa e hangai ana ki te ketone/ester; he whaiti ake te awhe pāmahana whakahaere i ngā polymer matatau.
Awhe Pāmahana: -30°C ki te +100°C (wā poto).
He mea tino pai mō: Ngā pūnaha hau kōpeke, ngā raina wahie miihini, te whakahaere hinu whakahinuhinu, me ngā waipēhi ahumahi e whakamahi ana i ngā hinu kohuke.
2.2 FKM (Rapa Warowaihā)
Ngā Kaha Matua: He ātete tino pai ki ngā pāmahana teitei, ngā matū, me te waikura. He pono te mahi a ngā hiri FKM i roto i ngā momo matū kino, tae atu ki ngā waikawa, ngā hinu hangai, me ngā hauwaiwaro kakara.
Ngā Here: He nui ake te utu; he iti te ngāwari i ngā pāmahana iti; kāore e hototahi ki ngā ketone, ngā esters, me te haukini.
Awhe Pāmahana: -20°C ki te +200°C (ngā tihi poto tae atu ki te 230°C).
He mea pai mō: Te tukatuka matū, ngā taputapu rongoā, ngā raina mamaoa pāmahana teitei, me ngā pūnaha turbo-aunoa.
2.3 EPDM (Ethylene Propylene Diene Monomer)
Ngā Kaha Matua: He ātete pai ki te wai wera, te mamaoa, te ozone, me te huarere. Ka ātete hoki ki ngā wai phosphate ester (hei tauira, Skydrol) me ngā waikawa/kawakawa waimeha.
Ngā Here: Kāore e pai mō te whakamahi hinu kohuke, wahie rānei; ka tere te pupuhi me te pakaru o te hinu mēnā ka pāngia.
Awhe Pāmahana: -40°C ki te +150°C (wā poto).
He mea tino pai mō: Ngā pūnaha maimoatanga wai, ngā ara iahiko whakamatao, te tukatuka kai me te inu, me ngā waipēhi rererangi e whakamahi ana i ngā phosphate esters.

| Te Whai Hua o te Utu | Ōhanga | Moni | Waenga |
4. He Tikanga Kōwhiringa Hanganga
Hipanga 1: Tautuhia te Pāpāho Wai
Wai, mamaoa, waipiro rānei: Ko te EPDM te mea tino pai nā te mea he pumau ki te wai.
Ngā hinu, ngā wahie, ngā hauwaiwai rānei: He pai te NBR, te FKM rānei, engari he pai ake te FKM mō ngā pāmahana teitei, ngā wai hangai rānei.
Pāpāho matū kaha: Manatokohia te hototahitanga mā te whakamahi i ngā tūtohi ātete matū; he maha ngā wā ka whakaratohia e te FKM te ātete whānui.
Hipanga 2: Aromatawai i te Pāmahana me te Pēhanga
Ngā taiao pāmahana teitei (>150°C): Me whakamahi te FKM, ngā pūmua motuhake rānei (hei tauira, te FFKM) hei karo i te koroheketanga tere.
Ngā tono mō te kiri-ā-rangi: Ka mau tonu te ngāwari o ngā rauemi e hangai ana ki te EPDM, ki te PTFE rānei i ngā pāmahana iti.
Ngā pehanga nui rawa: Me whakarite kia rite te kaha ā-ringa o te hiri me te hoahoa ārai-putanga ki te pehanga pūnaha.
Hipanga 3: Arotakehia ngā Here mō te Ora me ngā Here Utu
Ngā pūnaha poto te ora, kāore e tino hiahiatia: He taurite te mahi me te ōhanga a te NBR.
Ngā tono roa te ora, pakari, haumaru rānei: Hokohoko ki te FKM mō te whakaiti i te wā kore mahi me te whakapiki ake i te pono.
5. Ngā Mahanga me ngā Huanga Noa
Te whakamahi i te NBR me te mamaoa, te ozone rānei: Ka pā te mārō, te ngatata, me te turuturu i roto i ngā wiki.
Te whakamahi i te EPDM ki ngā paipa hinu: Ka hua ake te pupuhi tere o te hiri, te mauheretanga o te takirere, me te rahunga o te pūnaha.
Te whiriwhiri i te FKM mō ngā hau pāmahana-iti: Tērā pea ka pakarukaru ngā whati i raro i te -20°C me te kore he taumata pāmahana-iti.
6. Ngā Auahatanga o te Hangarau Keke ā-Mārama
Ngā Ranunga Mahi-Teitei: Ka whakarei ake ngā elastomers kī tonu i te PTFE i te ātete matū me te pāmahana me te whakaiti i te waku.
Ngā Hiri Atamai: Ka aroturukihia e ngā pūoko whakauru te kakahu, te pēhanga, me te pāmahana, ka taea ai te tiaki matapae.
Ngā Rauemi Tauwhiro: Kei te piki haere te aro o ngā ahumahi e aro nui ana ki te taiao ki ngā pūhui koiora me ngā matū hangarua.
Whakamutunga
Ehara te whiriwhiri rauemi hiri i te tukanga kotahi mō te katoa, engari he whakaritenga pūnaha o ngā āhuatanga rauemi ki ngā tono whakahaere. Ahakoa he pai te NBR i roto i ngā pūnaha hinu, ka ātete te FKM ki ngā matū kaha me ngā pāmahana teitei, ā, kāore he rite o te EPDM i roto i ngā tono wai me te mamaoa. Mā te mārama ki ēnei rerekētanga—me te whakamahi i ngā raraunga hangarau mai i ngā kaiwhakarato—ka whakarite i te mahi pai o te takirere, ka whakaiti i ngā utu huringa ora, ā, ka whakaiti i ngā mōrearea whakahaere.
Hei whakamōhiotanga tēnei tuhinga. Tirohia tonutia ngā pepa raraunga hangarau, ā, whakahaerehia ngā whakamātautau hototahi mō ngā tono motuhake.
