I roto i ngā āhuatanga whakaputa ahumahi maha, he mea tika kia kawehia ngā paru kei roto ngā matūriki totoka, pērā i ngā paru kohuke i roto i ngā maina, ngā toenga pungarehu i roto i ngā tipu hiko, me ngā wai whakarewa i roto i te ahumahi whakarewa. He kaha te waikura o ēnei paru, ā, he ātete ki te kakahu, ka nui rawa te tono mō ngā taputapu kawe. Ko tepapu parai silicon carbidei puta ake hei whakautu i tēnei tono, ā, kua noho hei tūāpapa mō te ao kawe waka ahumahi.
1, Te kaupapa mahi
Ko te papu parapara silicon carbide te kaupapa matua o te mahi a ngā papu centrifugal. Ina peia e te motuka te rakau papu kia huri i te tere teitei, ka huri hoki te impeller e hono ana ki te rakau papu i te tere teitei. Ka panaia e ngā mata o te impeller te wai e karapoti ana kia huri tahi. I raro i te mahi a te kaha centrifugal, ka whiua te wai mai i waenganui o te impeller ki te taha o waho, ā, ka piki ake te tere me te pēhanga. I tēnei wā, ka hangaia he wāhi pēhanga iti i waenganui o te impeller, ā, ka tomo tonu te parapara o waho ki te tinana papu mā te paipa momi i raro i te mahi a te pēhanga hau, hei tāpiri i te wāhi pēhanga iti i waenganui o te impeller. Ko te wai tere teitei e tukuna ana mai i te taha o waho o te impeller ka tomo ki te tinana papu āhua volute, ka huri anō i te kaha nekeneke o te wai hei kaha pēhanga, ā, ka mutu ka tukuna te parapara mai i te paipa tuku i te pēhanga teitei ake, ka tutuki ai te kawe tonu me te pumau.
2. Ngā painga matua
1. Ātete tino kaha ki te pakū
He tino teitei te pakeke o te warowaihā silicon, tuarua ki te taimana i runga i te pakeke Mohs. Mā tēnei ka tino whakaiti i te tere pakaru o ngā wāhanga rere-mā roto o te papu para warowaihā silicon ina pa ana ki te para kei roto he maha ngā matūriki totoka mārō. Ki te whakatauritea ki ngā papu para whakarewa tuku iho, ka taea te whakaroa i te roa o te ora o ngā papu para warowaihā silicon kia maha ngā wā, ka whakaiti i te auau o te whakakapinga me te tiaki taputapu, ā, ka whakapai ake i te haere tonu me te pumau o te whakaputanga.
2. Ātete pai ki te waikura
He pai te pumau matū o te warowaihā silicon, ā, ka taea e ia te tu atu ki te waikura mai i te nuinga o ngā waikawa kore-waro, ngā waikawa waro, me ngā turanga. I roto i ētahi ahumahi matū, whakarewa, me ētahi atu ahumahi, he kaha te waikura o te para. Mā te whakamahi i ngā papu para warowaihā silicon ka taea te ātete pai i te waikura o ngā matū, te whakarite i te mahi noa o ngā taputapu, me te karo i ngā tūponotanga haumaru pēnei i te turuturu me te kino o ngā taputapu i puta mai i te waikura.
3. Te pumau o te pāmahana teitei
Kei te silicon carbide anō hoki te āhuatanga o te ātete ki te pāmahana teitei, e taea ai te tu atu i ngā pāmahana tae atu ki te 1350 ℃. I roto i ētahi āhuatanga ahumahi pāmahana teitei, pērā i te kawe i te paru pāmahana teitei, ka taea e ngā papu paru silicon carbide te pupuri i te mahi pumau, ā, e kore e rerekē te āhua, e pakaru rānei i te pāmahana teitei, ka urutau ki ngā taiao mahi uaua.
3. Ngā Āpure Tono
1. Te umanga keri
I roto i te tukanga keri me te whakangao, me kawe te nui o te paru kei roto ngā momo matūriki o te konganuku. Ehara i te mea he nui te kukū o ēnei paru, engari he nui hoki te pakeke o ngā matūriki o te konganuku, ka nui te pakaru o te papu kawe. Nā te ātete pai ki te pakaru me te waikura, ka taea e te papu paru silicon carbide te kawe pai me te pumau i te paru, te whakapai ake i te pai o te whakaputa keri, me te whakaiti i ngā utu whakahaere.
2. Ahumahi whakarewa
Ko te whakaputanga whakarewa ko te kawe i ngā wai whakarewa me ngā para e tino pāwera ana, e tino waikura ana hoki. Ka taea e te papu para silicon carbide te tu atu ki ngā pāmahana teitei me te ātete ki te waikura matū, e tutuki ai ngā whakaritenga pakari o te umanga whakarewa mō te kawe taputapu me te whakarite kia maeneene te haere o te tukanga whakaputa.
3. Ahumahi hiko
He nui te toenga pungarehu ka puta mai i ngā tipu hiko i muri i te tahunga waro, me kawe ki ngā wāhi kua tohua hei tukatuka mā roto i ngā papu para. Ka taea e te papu para silicon carbide te aro atu ki te pakaru me te haehae o te pungarehu, te whakarite kia pono te mahi a te pūnaha kawe pungarehu, me te āwhina i te hanga tipu hiko e pai ana ki te taiao.
4. Ahumahi matū
He maha ngā wā ka pā te hanga matū ki ngā wai me ngā paru waikura he nui te waikura kei roto ngā matūriki totoka. Nā te ātete pai o ngā papu paru silicon carbide i te waikura kua whānuitia te whakamahinga i roto i te umanga matū, kia mau ai te haumaru me te pumau o te hanga matū.
Kua noho te papu parapara silicon carbide hei taputapu matua e kore e taea te whakamahi mō te kawe waka ahumahi nā tōna kaupapa mahi ahurei, ōna painga mahi tino pai, me ōna whānuitanga o ngā tono. I te whanaketanga tonu o te hangarau ahumahi, ka haere tonu te auaha me te whakapai ake o ngā papu parapara silicon carbide, ka whakarato i tētahi taurangi pakari ake mō te whakaputanga whai hua i roto i ngā momo ahumahi.
