He aha ngā Takirere Pūrerehua Mahi Teitei (HPBV)?

1. He aha ngā takirere pūrerehua mahi teitei

Ko te takirere pūrerehua mahi-teitei e pā ana ki tētahi momo hua takirere pūrerehua hou e whakapai ake ana i te ātete hiri me te kakahu o ngā takirere pūrerehua, e whakanui ake ana i te ātete pāmahana teitei me te ātete waikura, ā, e whakapai ake ana i te roa o te ratonga me te pono i runga i ngā takirere pūrerehua noa (ngā takirere pūrerehua porowhita me ngā takirere pūrerehua eccentric toru) mā te whakapai ake i te hanganga me ngā rauemi. Ki te whakatauritea ki ngā takirere pūrerehua noa, he roa ake te ora o ngā takirere pūrerehua mahi-teitei, he mama ake te taipana, he whānui ake te awhe pēhanga tono, ā, he pai ake te mahi hiri.

Ko ngā takirere pūrerehua mahi-teitei (HPBV) he whanaketanga matatau o te hoahoa takirere pūrerehua paerewa. I hangaia mō te hiri pai rawa atu, te pakari, me te whakahaere i roto i ngā tono nui, he āhua kōpae rerekē (takirua, takitoru rānei) ā, e whakamahi ana i ngā hiri whakarewa-ki-whakarewa, pakari rānei. Kāore i rite ki ō rātou hoa porowhita,ngā takirere pūrerehua mahi teiteiHe tino pai ki te whakahaere i ngā pēhanga teitei, ngā pāmahana tino kino, ngā mea waikura, ā, e ārai ana i te mirumiru, e kore ai e hiahiatia i roto i ngā tukanga ahumahi o ēnei rā.

1.1 Ngā Wāhanga Matua o te Takirere Pūrerehua: Tinana, Kōpae, Kakau, Nohoanga, me te Hononga Whakaoho

E rima ngā wāhanga matua o te takirere pūrerehua: te tinana takirere, te kōpae pūrerehua, te kakau takirere, te nohoanga hiri, me ngā wāhanga hononga actuator.

•Tinana TakirereKo te tinana takirere te anga matua o waho, e pikau ana i te pēhanga o te paipa me ngā kawenga waenga, ā, e mahi ana hoki hei turanga whakairi mō ngā wāhanga katoa. Kei te wātea i roto i ngā whirihoranga momo wafer me te momo lug, he mea hanga noa mai i te rino maka, te maitai waro, te maitai kore waikura rānei.

•Kōpae TakirereKo te kōpae pūrerehua te wāhanga nui mō te whakatuwhera, te kati, me te whakawhāiti. Ko tōna hoahoa āhua kōpae, e wātea ana i roto i ngā hanganga porowhita, āhua rerekē rānei, ka whakatau tika i te mahi hiri me te ātete ki te kakahu. Me ātete ki te waikura me te horo.

•Kākano TakirereKa tukuna te mana e te kakau takirere, ka hono i te kaiwhakaoho ki te kōpae hei whakahohe i te nekehanga hurihuri. He mea hanga ki te maitai kore waikura, me ngā hoahoa whakakaha me ngā hoahoa rahi mō ngā tono pēhanga teitei, whānui hei ārai i te piko, te whakarerekētanga rānei.

•Nohoanga TakirereHe mea nui te nohoanga hiri kia kore ai e turuturu. Kei roto i ngā rauemi rapa hiri-ngohengohe, i ngā rauemi whakarewa hiri-mārō rānei, e piri pūmau ana ki te kōpae kia kore ai e turuturu.

•Whakahoutiar: Kei roto i ngā wāhanga hononga o te actuator ngā kakau, ngā taputapu noke, me ngā actuator hiko/hau. Ka whakaratohia e rātou te taipana e tika ana mō te whakatuwhera me te kati, ka taea te whakahaere ā-ringa me te mana mamao aunoa. Ka mahi tahi ngā wāhanga katoa hei whakarite i te mahi pumau, te hiri pono, me te whakahaere tika o te takirere pūrerehua.

1.2 Te Tātaritanga o te Mātāpono Hoahoa Hanganga o te Takirere Pūrerehua Mahi-Teitei

He takirere pūrerehua mahi-teitei te takirere pūrerehua kua whakarārangihia ki te raina tika, he mea hanga ki te hangarau tino tika, he mea tino pai mō te whakahaere, te whakahaere rānei i te rere me te pēhanga i roto i ngā tono pēnei i te wai puna, te wai ahumahi, te wai para, te hau, te HVAC, te hau o te tāone, me te LPG. Ina kati, ka kore te takirere e turuturu.

Kei roto i te hanganga o te nohoanga takirere he hoahoa hiri pihi COS kua patenttia, e whakaiti ana i te waku i waenga i te kōpae me te nohoanga, e whakaiti ana i te taipana actuator, ā, e whakaroa ana i te roa o te nohoanga. He rite tonu te tukanga hiri ki te takirere takirua-kore. He porowhita te mata hiri o te kōpae, e whakarite ana i te pa maeneene i te wā e hiritia ana. Mā te whakaiti i te waku, inā koa i te hiri o te pou, ka whakaroa ake i te roa o te nohoanga. Ka kati aunoa te mowhiti pupuri whakarewa i roto i te mowhiti nohoanga i tetahi āputa i waenga i te kakau me te mowhiti nohoanga ina pāngia te kakau e ngā kaha kore taurite, ka whakakore i te tūponotanga o te turuturu tuaka.

•Piko COSMā te hoahoa hiri pihi COS ka kore e piki ake te taipana i mua i te hiritanga. I te wā e hiritia ana, ka pā te kōpae ki te mowhiti nohoanga puta noa i te porowhita 360° katoa i te wā kotahi, ka whakaiti i te waku, ka whakaheke i te taipana, ka roa ake te ora o te nohoanga, ā, ka kore e turuturu i te wā roa. Mā te waku me te taipana kua whakaitihia ka taea te whakamahi i ngā kaiwhakaoho iti-mana, ka whakaiti i ngā utu a te kaiwhakamahi.

•Kōpae Mīhini PorowhitaKa mīhinihia te kōpae kia puta he āhua porowhita katoa, ā, ko ia wāhanga o te mata hiri ka hanga he wāhanga porowhita. Ka tukatukahia te kōpae me te mowhiti nohoanga kia rite te āhua porowhita, ka iti ake te āputa, ā, kāore he waku. Ka huri maeneene te kōpae, ahakoa i ngā mata hiri tuaka i te tihi me te raro. Ahakoa te pa, he tino maeneene ngā mata hiri, ka whakaiti i te taipana me te whakarei ake i te mahi hiri.

•Takirere Pūrerehua Raina-PTFE Mahi-TeiteiHe kōhao tinana kua whakakikoruatia ki te PTFE tēnei takirere, ā, e whakamahia whānuitia ana i roto i ngā mahi kai, rongoā koiora, hikohiko, me ētahi atu mahi akuaku hei whakahaere, hei whakahaere rānei i te rere me te pēhanga o ngā wai rerekē, tae atu ki ngā mahi ahumahi matū e uru ana ki ngā waikawa kaha, ngā kawakore kaha, me ngā hau tino waikura. He tino pakari, he pai te mahi hiri, me te ātete waikura tino pai, ka kore e turuturu ina kati.

•Hoahoa Hiri Momo-IMā te hoahoa mowhiti hiri ka noho motuhake te rapa me te Teflon, engari ka tautokona anō hoki, ka whakarei ake i te mahi hiri. Mā te whakamahinga o te rapa ka whakapiki ake i te ngāwari o te hiri me te whakaiti i te nui o te rapa e hiahiatia ana, ka whakakorea te tūponotanga o te aukati kōpae i te tūranga kati nā te whānui o te rapa i te pikinga o te pāmahana.

Te Mahi Hiritanga Whakapai Ake o te Hoahoa Takirere Pūrerehua Mahi-Tiketike Hou:

a. Ko te arai PFA he 3 mm te matotoru, neke atu rānei, ka ārai i te urunga o ngā hau maha, ā, he kaha hoki te ātete ki te waikura.

b. Ka tāpirihia ngā puna ki ngā pouaka tākai o runga me o raro hei whakakore i ngā pānga o ngā piki me ngā heke o te pāmahana ki te hiri.
