I roto i te umanga hiri, he whānuitia te whakamahinga o ngā mowhiti-O polyurethane (PU) i roto i ngā taputapu waipēhi, ngā mīhini aunoa, ngā taputapu hiko hou me ētahi atu mara matua, nā te mea he tino ātete ki te haehae, he ātete ki te kakahu me te ngāwari. He raruraru roa kei te umanga: ahakoa ka whakamahia e ngā kaihanga ngā rauemi polyurethane mata rite tonu hei hanga mowhiti-O, he rerekētanga nui tonu ngā hua kua oti i roto i te kaha hiri, te ātete ki te huarere me te roa o te ratonga. Kua whakamanahia e te rangahau hangarau ahumahi kāore te hanganga tauira i te mea anake e wehewehe ana i te kounga o te hua. Ko te uira toenga mai i te tukanga hanga he hapa huna e kore e kitea. Kua whakarewahia e STMC (Nanjing) Precision Machinery he taputapu whakakore cryogenic tino tika me te tino whai hua, e aro nui ana ki ngā mamae whakakore o ngā mowhiti hiri mai i te pūtake me te whakamahi katoa i te kaha mahi o ngā rauemi polyurethane.
Ko te nuinga o ngā mowhiti-O PU ka hangaia mā te whakakōpeketanga me te whakamomona. Ka puta te mura me ngā pūwero iti ki te porowhita o waho nā te mea ka pakaru te pokepokea ai, ka puea ake ngā rauemi. Ko te nuinga o ngā kaihanga iti me te rahi e aro nui ana ki te arotau i te tauira, engari kei te whakawhirinaki tonu ki ngā tikanga tukatuka mata pērā i te kutikuti ā-ringa me te kutikuti me te whakakanapa i te wira huri hei tango i te pakaru. Kāore ēnei huarahi e tango i ngā pūwero iti-rahi, ā, ka rakuraku i ngā mowhiti-O ka puta he rerekētanga o ngā rahi. Mā te mura noa iho ka whakararu i te piri o te hononga i waenga i ngā mowhiti-O me ngā awaawa, ka puta he turuturu me te whakaiti i te pēhanga i raro i ngā āhuatanga whakahaere pēhanga teitei. Hei ngoikore o te hanganga i raro i te taumahatanga, ka ngawari te pakaru me te haehae o ngā pūwero i te wā o te nekehanga hurihuri o ngā taputapu, ka tino whakararu i te ātete haehae o te polyurethane. Hei tāpiri, he iti ake te ātete tawhito o ngā pūwero i te tinana matua o te hua. Ka tere te pirau i roto i te pāmahana teitei/iti me ngā taiao waikura, ka pakaru wawe te mowhiti hiri katoa. Ka pakaru hoki ngā ara iahiko hinu me ngā wāhanga tika o te mīhini i ngā para e hinga ana.
Ko te whakakorenga cryogenic tino tika te otinga tino pai hei whakakore i ngā hapa uira me te whakanui ake i te mahi a ngā rauemi. Hei umanga hangarau-tiketike ā-motu me te umanga "Mātanga, Whakapaipai, Rerekē me te Auaha" o te Porowini o Jiangsu me te neke atu i te tekau tau o te tohungatanga ki te hangarau whakakorenga pāmahana-iti, ka whakamahia e STMC ngā āheinga R&D tahi a Sino-Hapanihi me ngā hangarau patent maha hei tuku i ngā otinga whakakorenga cryogenic kua whakaritea katoa e whakatapua ana ki ngā mowhiti hiri PU.
He pūnaha whakahaere pāmahana tino tika tēnei e pupuri ana i te iti o te rerekētanga pāmahana, ā, ka pakaru tika te taputapu i ngā taha o te taputapu i ngā pāmahana iti, me te pupuri tonu i te ngāwari me ngā āhuatanga ā-tinana o te tinana PU O-ring. He hanganga pupuhi pāpāho tere-teitei takirua te impeller, ka tangohia katoatia te uira mai i ngā koki katoa me te kore e kino ngā āhuatanga o te hua, te mata o te mata, te hanganga ngota rānei o te rauemi. He maeneene, he ātaahua hoki ngā taha o ngā hua kua oti, ā, he tino ōrite te āhua o te hanga papatipu, e tutuki ana i ngā paerewa tango i ngā pakaru tino tika.
Mō te whai huatanga o te whakaputanga, ka whakanuia ake te hua e ngā taputapu whakakorenga wai aunoa a STMC ki te whakataurite ki ngā mahi ā-ringa. Ka taea te tukatuka nui i ngā mowhiti-O PU, ka whakaitihia ngā utu mahi me te whakaiti i ngā reiti hapa me te whakataurite i te kounga teitei me te whai huatanga o te whakaputanga papatipu. Ka kitea ngā whakapainga whānui o ngā mowhiti-O PU e tukatukahia ana e tēnei taputapu i roto i te mahi hiri, te ātete ki te pāmahana teitei me te pāmahana iti, me te roa o te aukati i te koroheketanga. Me ngā rauemi mata ōrite, he nui ake te pai o tā rātou mahi whānui i ngā hua e tukatukahia ana e ngā tikanga whakakorenga wai tuku iho.
Kua pūrongo ngā kaihanga o ngā hiri motuka me ngā wāhanga waipēhi i roto i ngā whakamātautau mara, whai muri i te whakamahi i ngā otinga whakakore hiri a STMC, ka roa ake te ora o ngā mowhiti hiri, ā, ka tino heke te reiti pakaru o ngā taputapu. Kua kaha ake te whakataetae o ā rātou hua i roto i ngā mākete tuku tono me ngā mākete tautoko utu nui.
I ēnei rā, kua kaha ake te whakataetae ōrite mō ngā rauemi mata i roto i te umanga hiri, ā, ko te whakawhirinaki anake ki te whakapai ake i te tauira kāore e taea te tautoko i te whanaketanga. Mā te tautoko a ngā taputapu whakakore i ngā pakaru matua tino tika me te tino whai hua, ka āwhina a STMC i ngā kaihanga ki te whakakore i ngā hapa uira huna mai i te pūtake me te whakapau kaha ki te mahi a ngā rauemi PU O-ring. Ko ngā tikanga hanga pakari me te pai te tautoko i ngā hua hiri tino mahi. Mā te whakamanahia e ngā taputapu ngaio, ka taea e ngā kaihanga hiri te wehe atu i te whakataetae utu iti, te whakawhanake i ngā hua hiri pumau me te kounga teitei, me te akiaki i te umanga hiri rapa me te kirihou katoa ki te tika ake, te roa ake o te ratonga me te aunoatanga katoa.
