E whakamārama ana tēnei pepa i te ariā taketake me te tikanga tatau mō te ine i te pauna maha-upoko.

Kaituhi: Smartweigh– Taumaha Upoko Maha

He mea tino nui te pūmanawa pūnaha puranga aunoa mō te whakahaere, te ine me te kimi i roto i te tukanga hanga o te wheketere waro a te kamupene, he pānga nui tēnei ki te kounga o ngā hua i hangaia me te tukatuka mā te anodizing i roto i te wheketere waro. Te hanganga tauine (whakamōhio mai te ingoa). E ai ki te rangahau nui, ngā mahi mahi pāpori me te rangahau pūtaiao o ngā pauna maha-upoko e toru, he iti noa iho taku māramatanga me te pūkenga ki ngā pauna maha-upoko. Anei te kī ki te hanga i tētahi ine māmā me te taipitopito o ngā ariā taketake me ngā tikanga tatau o ngā pauna maha-upoko e toru. Whakamōhio mai me te mahi kaha ki te katoa. Ko te hanganga hanganga tuatahi.

I te nuinga o te wā, ko te pauna maha-upoko he mea tito mai i ngā wāhanga matua pērā i te paipa whāngai, te peere pauna, te taputapu whakaoho, ngā taputapu mīhini whāngai, te whatanga, te pūtau kawenga me ngā taputapu ine me te whakamātautau. E rua ngā oko pauna. Ko te oko pauna te whakaurunga o ngā rauemi mata ki te pauna rauemi mata. Me whai whakaaro te kōwhiringa o ngā tauira rauemi mata ki te ātete waikura me te ātete waikawa. Ka tīpakohia te rahinga pauna o ngā rauemi mata i runga i te putanga katoa o te whāngai i roto i te 3 meneti, ā, me whai wāhi te wā whāngai mō te tukanga pauna katoa. 10% pea.

Ko te tuatoru ko ngā mīhini whakaranu. Ko te taputapu whakaoho te nuinga o te wā e whakamahia ana hei āwhina i te whāngai i ngā rauemi mata kāore i te tino rere. Ko te tikanga he mea hanga mai i tētahi motuka taraiwa o tētahi ringa pakaru-āwhati kei roto he mata porowhita, he niho whao rānei. Ka taka mārire ngā rauemi mata o te kōhao ki te tomokanga me te putanga. 4. Ngā taputapu whāngai.

Ka whakamahia ngā taputapu kawe hei kawe i ngā rauemi mata muka matū i roto i te pauna pauna. E ai ki ngā āhuatanga o ngā rauemi mata hei kawe me te taiao matawhenua o te tono, ka taea te whakamahi i ngā kaikawe tīwiri, ngā kaikawe impeller centrifugal, me ngā kaikawe whitiki tuku. I te nuinga o te wā, he kaha ake ngā kaikawe tīwiri i ētahi atu mīhini whāngai kati, ā, kāore e taea anake te kawe i ngā rauemi mata kia ōrite, engari ka ārai hoki i te tauhiuhi me te pupuhi o ngā rauemi mata paura. Ko te tuarima ko te anga tautoko kāri oro o waho.

Ko te hanganga pūoko oro te tinana tautoko o ētahi atu taputapu miihini me ngā taputapu mīhini, ā, kua tāutahia te pūtau kawenga ki runga. 6. Pūoko pauna He wāhanga pauna nui te taumaha kupenga o te pauna maha-upoko. Ka tīpakohia e ia te pūoko ine taumaha ātete teitei-taumira, e huri ana i te tohu taumaha kupenga o ngā rauemi mata hei tohu raraunga taputapu hiko hei putanga. 7. Te ine me te whakamātautau i ngā taputapu whakahaere.

Ko ngā taputapu ine me te whakahaere he mea tito mai i tētahi mata pauna maha-upoko atamai me tētahi pūnaha whakahaere aunoa aunoa, e whakamahia ana hei whakahaere me te ine i te tere kawe o ngā rauemi mata me te kaha kawe. Hei tāpiri, ko te tauranga whāngai me te tauranga whāngai o te pauna maha-upoko me whiriwhiri i ngā hononga ngohengohe ā-roto, ātete-paru, ā-hiri hoki, kia kore ai e ngāwari te whakararu i te pauna i waenga i te ipu rokiroki me ngā taputapu e whai ake nei. He pauna maha-upoko te hopa taumaha, ā, ko te whāngai whakarerekētanga e mau ana ki runga i tētahi pūtau kawenga e mau ana ki te anga.

Tuarua, te paerewa. Tuatahi, te paerewa. Ko te whakamātautau ine ine e hangai ana ki te ariā taketake o te whakahaere i ngā tūponotanga taumaha kupenga puta noa i te tukanga mahi.

Tuatahi, paunatia ngā taputapu mīhini tapahi me te pūwero pauna, whakatakotoria te tere tapahi tuturu kia rite ki te kino o te taumaha kupenga mō ia wā, kātahi ka whakahaere i ngā taputapu mīhini tapahi kia puta ai te tere tapahi tuturu. He tika, he ōrite hoki ngā tawhā whakahaere, ā, i roto i te wā poto, ka whakamahia e ngā taputapu mīhini tapahi te kaha taunekeneke i te wā o te tukanga tapahi katoa kia mahi ai ngā tohu whakahaere kua rongoatia i waenganui me muri o te mahi kia rite ki te ariā taketake o te rōrahi. Ko te tuarua ko te pauna o te tukanga katoa. Ka hurihia te taumaha kupenga o ngā rauemi mata i roto i te pūwero pauna hei taputapu hiko kia rite ki te taumaha o te pūoko, ā, ka tukuna ahokore ngā raraunga ki te pouaka pauna maha-upoko. He rerekē, kia rite ki te whakahaere PLC o te kuaha wai whāngai, ka tapahia te pūwero pauna.

Hei tāpiritanga, ka whakataurite te papa taputapu i roto i te waka pauna i te tere whāngai tūturu i inehia tika (rerenga whakatuwheratanga) ki te tere whāngai kua whakaritea, ā, ka whakamahi i te whakatikatika PID hei whakahaere i te mahi tūturu o ngā mīhini me ngā taputapu whāngai, kia taea ai te whakarite i te tere whāngai tūturu. Ka whai tika te tere whāngai i te uara kua whakaritea. Ina whakatuwheratia te kuaha wai whāngai hei whāngai ki roto i te hopper pauna, ka raka te tohu raraunga whakahaere i te tere whāngai, ā, ka tīmata te whāngai rōrahi. Ka whakaatuhia e te pouaka pauna maha-upoko ngā ihirangi mōhiohio o ngā rauemi e haere mai ana me ngā rauemi e haere atu ana, e whakaatu ana i te tere tūturu o ngā rauemi e haere mai ana me ngā rauemi e haere atu ana, ā, ka whakaatu i ngā mōhiohio mō te taumaha kupenga katoa o ngā kai. Ko te tuatoru ko te ine tika i te tere whāngai.

Ko te tere whāngai (rere whakatuwheratanga) o te pauna maha-upoko ko te uara kino taumaha kupenga mō ia wā, e tatauhia ana i roto i te ariā mā te tātai mt=dG/dt. Ko te nui ake o te tere tapahi; ko te uara kino kupenga, arā, ko te dG ka ine tika i te wā dt. Ka taea e te pauna maha-upoko te ine tika i te tere paahitanga mā te pēhi me te pupuri i raro i te āhua e whakaaturia ana.

mt=n(d±β*d1)/(t±t) Kei te tatauhia te tātai. E whakaatu ana te mata pauna d-maha-upoko i te awhe. E tohu ana ngā mōhiohio whakaatu-n i te maha o ngā whakawhiti tauine o te ihirangi mōhiohio.

D1- Ko te taumira mata o te mata o roto o te papa taputapu i roto i te waka pauna ko te uara tohu hapa ine, e tohuhia ana e β=O.6. TD - te ine tika o te wā o te pūnaha tohanga toto. Te - te uara tohu o te take o te tuhi hapa i te wā e tuhi ana, ko te tikanga te=0.001.

4. Tātaihia te taumaha katoa. Ko te taumaha kupenga katoa Gq i roto i te wā huringa katoa o te pauna maha-upoko he wāhanga e rua, arā, ko te whakamātautau ine i te pouaka pauna maha-upoko me te taumaha kupenga o te mata pauna maha-upoko VA, me te taumaha kupenga o te pouaka pauna maha-upoko V kāore i inehia i te wāhanga o mua. . tātaitanga tātai gq=va+VD hua=(hua+hua)-(hua-hua)-0CD=MTL*TF.

VH- Ko te uara rohenga o runga o te taumaha kupenga i mua i te paunatia o ngā taonga i roto i te whare putunga. Te Whakakīnga - Ko te uara rohenga o raro o te whakakīnga i roto i te ipu pauna. $H - te uara rohenga o te taumaha kupenga nā te hapa pauna.

He iti iho te taumaha kupenga i te uara kua tohua nā te hapa i puta mai i te pauna. MTL - Te tere whāngai raka i te wā whāngai. TF - te wā whakatau tata.

Kei te whakaatuhia tonutia te tere whāngai raka MTL i roto i te taumaha kupenga ia hekona K whakawhiti. E whakaatu ana te awhe: mtl=K(d±β*d1)/(1±te) Wā whāngai Rere kai kuaha wai whāngai MF, MF=10MT. Ko te wā katoa tuturu o TF=VA/MF ko: TE=TF+TD. Ko te tere rere toharite ko: mq=gq/tn I roto i ia pūnaha huringa, ka tāpaetia tonutia te taumaha kupenga o te rauemi mata, ā, ka taea te ine tika i te taumaha kupenga tn katoa i te wā t=0.

Tuarima, ngā hua. I roto i ētahi atu taputapu me ngā mīhini pauna, nā te hononga o ngā rauemi mata, ka huri te taumaha o te pūtau kawenga i te pāmahana, ka whakaiti i te tika o te pūnaha, engari ka whakakorea e te pauna maha-upoko aua hapa, ā, he uaua ki te whakaiti i te tika o te pauna. He tino māmā te take, ko te ine tika o te tere whāngai o te pauna maha-upoko e ahu mai ana i te rerekētanga taumaha kupenga, ehara i te rerekētanga taumaha kupenga, nō reira he whānui te whakamahinga o te pauna maha-upoko i roto i te pūnaha kawe rauemi mata muka matū.
