He mea nui te kawe rauemi whai hua, pumau hoki i roto i te awa roa o te whakaputanga ahumahi. Hei taputapu matua mō te kawe i ngā mea waikura kei roto ngā matūriki totoka, ka pā tika te mahi a ngā papu para ki te whai huatanga me te utu o te whakaputanga. I te haere tonu o te whanaketanga o te pūtaiao rauemi, kua puta ake ngā papu para uku silicon carbide, e kawe mai ana i tētahi otinga hou ki te mara kawe ahumahi.
Ko te nuinga o ngā papu parapara tuku iho he mea hanga ki ngā rauemi whakarewa. Ahakoa he pakeke te āhua, he uaua ki te whakataurite i te ātete ki te kakahu, te waikura, me te ātete ki te pāmahana teitei ina pāngia e ngā āhuatanga mahi uaua. I roto i te umanga tukatuka kohuke, ka taea te whakakore i ngā papu parapara whakarewa nā te kakahu kino me te haehae i roto i ngā rā torutoru noa iho, ehara i te mea ka hua ake he utu nui nā te whakakapinga taputapu maha, engari ka aukatihia hoki te whakaputanga, ka pā kino ki te whai huatanga o te umanga. Nā te putanga mai o ngā papu parapara uku silicon carbide kua angitu te whakakore i tēnei raruraru.
Ngā rauemi uku silicon carbideHe maha ngā āhuatanga tino pai. He tino teitei tōna pakeke, tuarua ki te taimana i roto i te pakeke Mohs, e whakarato ana i te papu para ki te ātete kakahu tino kaha, e ātete ana i te horo me te kakahu o ngā matūriki totoka, me te whakaroa i te roa o te ratonga o ngā taputapu. I taua wā anō, he pumau ngā āhuatanga matū o ngā uku silicon carbide, ā, ka taea te ātete ki te waikura o ngā matū waikawa me te kawakore rerekē engari ko te waikawa hydrofluoric me te kawakore wera kukū. Ka taea hoki e rātou te tu atu ki ngā pāpāho waikura kaha me te haumaru. Hei tāpiri, he pai hoki te ātete pāmahana teitei, ā, ka taea te pupuri i te mahi pumau i roto i ngā taiao pāmahana teitei me te kore e rerekē te ahua, te kino rānei nā ngā huringa pāmahana.
Kua tino whakaatuhia ngā painga o te papu para uku silicon carbide i roto i ngā mahi. Nā tōna roa o te ora mahi ka tino whakaiti i te utu whakamahi katoa. Nā te whakamahinga o ngā uku SiC i roto i ngā wāhanga au nui, he maha ngā wā o tōna ora mahi i te utu o ngā koranu ātete-kakahu. I roto i te wā kotahi o te waeine mahi, ka tino whakaitihia te utu o te whakapaunga taputapu, ā, ka whakaitihia hoki ngā utu tiaki me ngā wāhanga e manawapa ana. Mō te whakapaunga pūngao, ko te ōwehenga o ngā impeller uku he kotahi-tuatoru noa iho o te ōwehenga o ngā koranu ātete-kakahu. He iti te oma radial o te rotor, ā, he iti te kaha, e kore e whakapai ake i te pai o te mahi, engari ka roa ake hoki te wā mahi pumau o ngā wāhanga rere uku i roto i te rohe tino pai ki te whakataurite ki ngā papu whakarewa tuku iho, ka penapena i te whakapaunga pūngao huringa mahi katoa. Kua arotauhia hoki te pūnaha hiri pou, kua whakatauritea ki ngā rauemi wāhanga au nui uku mō ngā whakapainga e rite ana, ka whakaiti i te auau tiaki whānui, ka taea ai e te taputapu te mahi tonu mō te wā roa, ka whakarite i te haere tonu o te whakaputa, me te whakapai ake i te kaha whakaputa.
He whānuitia te whakamahinga o ngā papu para uku silicon carbide i roto i ngā ahumahi maha pēnei i te keri maina, te whakarewa, te hiko, me te miihini matū. I roto i te keri maina, ka whakamahia hei kawe i te para kei roto he nui ngā matūriki o te konganuku; I roto i te umanga whakarewa, ka taea te kawe i ngā para whakarewa tino waikura; I roto i te mara hiko, ka taea te kawe i te pungarehu me te para mai i ngā tipu hiko; I roto i te hanga matū, he ngāwari hoki te kawe i ngā rauemi mata me ngā hua waikura.
Hei umanga e tohunga ana ki te rangahau me te hanga papu paru uku silicon carbide i roto i te umanga, e piri tonu ana a Shandong Zhongpeng ki te wairua auaha, ā, e tūhura tonu ana i te whakamahinga pai o ngā rauemi uku silicon carbide i roto i te mara o ngā papu paru. Mā te whakauru i ngā hangarau matatau me te whakatipu i ngā pūkenga ngaio, kua wikitoria mātou i ngā uauatanga hangarau maha, ā, kua hangaia he hua papu paru uku silicon carbide me te mahi tino pai me te kounga pono. Mai i te tirotiro pakari o ngā rauemi mata, ki te whakahaere tika i ngā tukanga whakaputa, ki te tirotiro kounga o ngā hua, e whai ana mātou kia hiranga i ngā āhuatanga katoa, ā, e whakapau kaha ana ki te whakarato i ngā otinga kawe kounga teitei ki ngā kiritaki.
I te tirohanga whakamua ki te heke mai, me te auahatanga tonu o te hangarau, ka whanake haere ngā papu parai uku silicon carbide kia pai ake ai te whai huatanga me te mohio. Ki taku whakaaro, ā tōna wā tata nei, ka nui ake te mahi nui i roto i te ao o te kawe waka ahumahi, ka akiaki i te whanaketanga o ngā momo ahumahi.
