I roto i te ao ahumahi, ka kitea ngā papu para i ngā wāhi katoa, ā, he taputapu matua ēnei hei whakarite kia maeneene te haere o ngā tukanga whakaputa. I tēnei rā, me tūhura tātou i te mātāpono mahi opapu parai silicon carbidengātahi, kia kite ai me pēhea tana mahi nui i runga i te atamira ahumahi.
1, Te kaupapa mahi taketake o te papu paru
Ko te papu parapara he papu tohanga. Ka tīmata te hurihanga o te impeller i te tere tere, pērā i te mira hau e tere hurihuri ana, ā, ka panaia e ngā mata o te impeller te wai e karapoti ana kia huri tahi. Ka makahia te wai ki waho i raro i te mahi a te kaha tohanga, ā, ka tere te maka mai i waenganui o te impeller ki te taha o waho o te impeller. I tēnei wā, ka nui te kaha nekeneke o te wai, pērā i te kaitākaro e oma ana i te tawhiti i te tere tere me te āwhina tere teitei.
I te panga o te wai ki te taha o waho o te impeller, ka hangaia he wāhi pēhanga iti ki waenganui o te impeller, he rite ki te wāhi iti takoto kau me te pēhanga iti. Ā, ko te wai i waho kei roto i te taiao pēhanga teitei, he rite ki te wai e rere ana ki raro. I raro i te rerekētanga pēhanga, ka rere tonu te wai i waho ki waenganui o te impeller hei whakakī anō i te wai i makahia ki waho.
I muri i te urunga o te wai ki roto i te anga papu, ka heke haere te tere o te rere o te wai nā te whānui haere o te awa rere o te anga papu, pērā i te awa e whānui haere ana. I roto i tēnei tukanga, ka hurihia tētahi wāhanga o te pūngao nekeneke hei pūngao pēhanga tūmau, he rite ki te motuka e āta pōturi haere ana, e huri ana i te pūngao i kawea mai e te tere ki ētahi atu momo pūngao. Hei whakamutunga, ka haria te wai ki waho o te awa tuku i te pēhanga teitei ake, ka oti te mahi kawe kotahi. I te mea kei te huri tonu te impeller, ka haere tonu tēnei tukanga, ā, ka mimitihia tonutia te wai ki roto, ka pēhia ki waho.
2, Ko te āhuatanga ahurei o te papu paru silicon carbide
Ko te arotahi a Shandong Zhongpeng ki ngā uku karawiti silicon kua whakakorikoria, ā, he tino pai ngā painga o te papu paru karawiti silicon i hangaia mai i tēnei rauemi.
1. Ātete kakahu tino pai
He tino teitei te pakeke o ngā uku karāhe silicon, ā, ko te pakeke Mohs te tuarua o te taimana i roto i te āhua. He tino ātete ki te kakahu, he rite ki te mau i tētahi pukupuku kaha, ā, ka taea te ātete ki te mimiti tonu o ngā matūriki totoka i roto i te para para. Ki te whakatauritea ki ngā papu para whakarewa tuku iho, ka roa ake te ora o ngā papu para karāhe silicon. I roto i ētahi āhuatanga ahumahi e hiahia ana ki te mahi roa me te kawenga nui, pērā i te keri, te whakarewa me ētahi atu ahumahi, ka taea e ngā papu para karāhe silicon te mahi pumau, ka whakaiti i te raruraru me te utu e puta mai ana i te whakakapinga taputapu auau.
2. Ātete pai ki te waikura
He tino pai te pumau matū o te karawiti silicon, ā, ka taea e ia te tu atu i te waikura roa mai i ngā mea tino waikura. I roto i ngā ahumahi pēnei i te mahi whakarewa matū, he maha ngā wā e tika ana kia kawehia ngā wai waikura, ā, ka ngawari te pakaru o ngā papu whakarewa noa i te mimiti o ēnei mea. Ā, he rite te papu para karawiti silicon ki tētahi toa toa kāore e wehi i te waikura, ka taea te mahi noa i roto i ngā taiao uaua, e whakarite ana i te haere tonu o te whakaputa me te whakaiti i ngā utu tiaki me te whakakapinga taputapu.
3. He pai te ātete ki te pāmahana teitei
Ka taea e te papu parai silicon carbide te tu atu i ngā pāmahana teitei o te 1350 ℃, ka taea ai e ia te mahi pumau i roto i ngā taiao pāmahana teitei. I roto i ētahi mahi ahumahi e whakamahi ana i ngā tukanga pāmahana teitei, pērā i ngā oumu uku me te whakarewa maitai, ka taea e ngā papu parai silicon carbide te whakatutuki i ngā whakaritenga mahi motuhake me te whakarato i ngā otinga pono mō te kawe i ngā pāpāho pāmahana teitei.
3, Ngā mara tono o te papu paru silicon carbide
Nā ēnei āhuatanga tino pai, kua whānuitia te whakamahinga o ngā papu paru silicon carbide i roto i ngā momo mara pēnei i te keri me te whakarewa, ā, he mea nui tēnei i roto i te kawe waka ahumahi me tōna kaupapa mahi ahurei me te mahi tino pai. Me te haere tonu o te whanaketanga me te auahatanga o te hangarau, e whakapono ana mātou ka whakaatuhia e ngā papu paru silicon carbide ōna painga i roto i ngā mara maha atu, ka nui ake te pai me te iti iho o ngā utu ki te whakaputanga ahumahi.
