Leli phepha lichaza umqondo oyisisekelo kanye nendlela yokubala yokuthola ukulinganisa isisindo samakhanda amaningi

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Isofthiwe yesistimu yokuhlanganisa ngokuzenzakalelayo iyisistimu yokulawula, yokulinganisa kanye nokuthola ebaluleke kakhulu enqubweni yokwakha ifektri yekhabhoni yenkampani, enomthelela omkhulu ekhwalithini yemikhiqizo ekhiqizwa futhi ecutshungulwa ngokufaka i-anodizing efektri yekhabhoni. Ukwakheka kwesikali (ngethula igama). Ngokusho kocwaningo olujulile, imisebenzi yokuzijwayeza kwezenhlalo kanye nocwaningo lwesayensi lwezikali ezintathu zamakhanda amaningi, nginokuqonda okungaphezulu kanye nobuchwepheshe bezikali zamakhanda amaningi. Nasi isihluthulelo sokwenza isilinganiso esilula nesiningiliziwe semiqondo eyisisekelo kanye nezindlela zokubala zezikali ezintathu zamakhanda amaningi. Ngenisa futhi usebenze kanzima nawo wonke umuntu. Ukwakheka kokuqala kwesakhiwo.

Ngokuvamile, isikali sekhanda eliningi sakhiwe yizingxenye eziyinhloko ezifana ne-feeding sluice, ibhakede lokulinganisa, idivayisi yokuxuba, imishini yomshini wokudla, i-rack, i-load cell kanye nokulinganisa nokuhlola imishini yokusebenza yangempela. Ama-weigh hopper amabili. I-weigh hopper ukufakwa kwezinto zokusetshenziswa ezilinganisweni zezinto zokusetshenziswa. Ukukhethwa kwamamodeli ezinto zokusetshenziswa kufanele kucabangele ukumelana nokugqwala kanye nokumelana ne-asidi. Umthamo wesisindo wezinto zokusetshenziswa ukhethwa ngokuya ngomphumela ophelele wokudla ngemizuzu emi-3, futhi isikhathi sokudla kufanele sibheke yonke inqubo yokulinganisa. 10% noma ngaphezulu.

Okwesithathu imishini yokuxuba. Idivayisi yokuxuba isetshenziswa kakhulu ukusiza ukondla izinto zokusetshenziswa ngoketshezi olubi. Ngokuvamile yakhiwe ngenjini yokushayela yengalo ephula umugqa equkethe i-spiral auger blade noma amazinyo ezipikili. Izinto zokusetshenziswa zomgodi ziwela kahle emnyango nasemphumeni. 4. Imishini yokondla.

Imishini yokuthutha isetshenziselwa ukuthutha izinto zokusetshenziswa zefayibha yamakhemikhali esikalini sokulinganisela isisindo. Ngokwezici zezinto zokusetshenziswa ezizothuthwa kanye nendawo okuyosetshenziswa kuyo, kungasetshenziswa ama-screw conveyor, ama-centrifugal impeller conveyor, kanye nama-transporter ebhande lokudlulisa. Ezimweni eziningi, ama-screw conveyor anamandla kuneminye imishini yokudla evaliwe futhi awakwazi nje ukuthutha izinto zokusetshenziswa ngokulinganayo, kodwa futhi avimbele ukuchitheka nokuchitheka kwezinto zokusetshenziswa ezimpuphu. Okwesihlanu uhlaka lokusekela ikhadi lomsindo langaphandle.

Isakhiwo senzwa yomsindo siwumzimba wendawo yokusekela eminye imishini yomshini kanye nemishini yomshini, futhi iseli lomthwalo lifakiwe kuso. 6. Inzwa yokukala Isisindo esiphelele siyingxenye ebalulekile yesisindo se-multihead weigher. Ikhetha inzwa yokulinganisa ukucindezeleka enesinqumo esiphezulu, eguqula isignali yesisindo esiphelele sezinto zokusetshenziswa ibe isignali yedatha yedivayisi kagesi ukuze kukhishwe. 7. Ukulinganisa nokuhlola imishini yokulawula.

Imishini yokulinganisa nokulawula yakhiwe nge-dial ehlakaniphile yesisindo samakhanda amaningi kanye nesistimu yokulawula ezenzakalelayo ezenzakalelayo, esetshenziselwa ukulawula nokukala izinga lokuthuthwa kwezinto zokusetshenziswa kanye nomthamo wokuthutha. Ngaphezu kwalokho, i-port yokudla kanye ne-port yokudla ye-multihead weigher kufanele ngokuvamile ikhethe ukuxhumana okuthambile okuvimbela ukungcola nokuvala okuhambisanayo okuhambisanayo ukuqinisekisa ukuthi ukuxhumana phakathi kwebhini lokugcina kanye nemishini elandelayo akulula ukuvimbela isisindo. I-heavy hopper iyi-multihead weigher, futhi i-feeder elungisekayo ifakwe kuseli lomthwalo elinamathele kufreyimu.

Okwesibili, indinganiso. Okokuqala, indinganiso. Ukuhlolwa kwe-metrological kusekelwe emqondweni oyisisekelo wokulawula izingozi zesisindo esiphelele kuyo yonke inqubo yomsebenzi.

Okokuqala, kala imishini yomshini wokusika kanye ne-wearing hopper, setha isivinini sangempela sokusika ngokwemonakalo wesisindo esiphelele ngesikhathi seyunithi, bese ulawula imishini yomshini wokusika ukuze wenze isivinini sangempela sokusika. Amapharamitha okulawula anembile futhi ayaguquguquka, futhi esikhathini esifushane, imishini yomshini wokusika isebenzisa amandla okusebenzisana phakathi nayo yonke inqubo yokusika ukwenza izimpawu zokulawula ezigcinwe ezigabeni eziphakathi nezakamuva zomsebenzi ngokuya ngomqondo oyisisekelo wevolumu. Okwesibili ukukala yonke inqubo. Isisindo esiphelele sezinto zokusetshenziswa eziku-wearing hopper siguqulwa sibe amadivayisi kagesi ngokuya ngesisindo senzwa, futhi idatha idluliselwa ngaphandle kwentambo ku-multihead wearinger case. Ngokuphambene nalokho, ngokuya ngokulawulwa kwe-PLC kwesango lamanzi okudla, i-wearing hopper iyanqunywa.

Ngaphezu kwalokho, iphaneli yezinsimbi emotweni enesisindo iqhathanisa izinga lokudla langempela elilinganiswe ngokunembile (ukugeleza kokuvula) nezinga lokudla elisethwe kusengaphambili, futhi isebenzisa ukulungiswa kwe-PID ukwenza ukusebenza kwangempela kwemishini yokudla nemishini, ukuze izinga lokudla langempela lilungiswe. Izinga lokudla lilandelela ngokunembile inani elisethwe kusengaphambili. Lapho isango lamanzi okudla livulwa ukuze lifake i-weighing hopper, isignali yedatha yokulawula ivala izinga lokudla, bese iqala ukondla ngevolumu. Ikesi lesisindo esinezinhloko eziningi libonisa okuqukethwe kolwazi lwezinto ezingenayo neziphumayo, libonisa izinga langempela lezinto ezingenayo neziphumayo, futhi libonisa ulwazi mayelana nesisindo esiphelele sezithako. Okwesithathu ukulinganisa okunembile kwezinga lokudla.

Izinga lokuphakelwa (ukugeleza kokuvula) kwesikali samakhanda amaningi yinani lomonakalo wesisindo esiphelele ngesikhathi seyunithi, elibalwa ngokwethiyori ngefomula mt=dG/dt. Uma isivinini sokusika sikhulu; inani lomonakalo eliphelele, okungukuthi i-dG ilinganisa ngokunembile isikhathi se-dt. Isikali samakhanda amaningi singalinganisa ngokunembile izinga lokudlula ngokucindezela nokubamba ngaphansi kwesimo esibonisiwe.

mt=n(d±β*d1)/(t±t) Ifomula iyabalwa. Idayela lesisindo se-d-multihead libonisa ububanzi. Ulwazi lwe-n-Display lubonisa inani lokuguqulwa okulinganiselwe kokuqukethwe kolwazi.

D1- Isixazululo sesikrini sesikrini sangaphakathi sephaneli yezinsimbi emotweni enesisindo yinani lenkomba yephutha lokulinganisa, elivame ukuboniswa yi-β=O.6. I-TD - ukulinganisa okunembile kwesikhathi sesistimu yokujikeleza kwegazi. I-Te - inani lenkomba yesizathu sokurekhoda amaphutha ngesikhathi sokurekhoda, ngokuvamile i-te=0.001.

4. Bala isisindo esiphelele. Isisindo esiphelele i-Gq esikhathini somjikelezo ophelele wesisindo samakhanda amaningi siqukethe izingxenye ezimbili, okungukuthi isivivinyo sokulinganisa icala lesikali samakhanda amaningi kanye nesisindo sedayili esinamakhanda amaningi i-VA, kanye nesisindo sedayili esinamakhanda amaningi i-V esingalinganiswanga esigabeni esedlule. . gq=va+VD product=(product+product)-(product-product)-0CD=MTL*TF calculation.

VH- Inani eliphezulu lomkhawulo wesisindo esiphelele ngaphambi kokukala isitokwe sendawo yokugcina izinto. Izinongo - Inani eliphansi lomkhawulo wezinongo esitsheni sokukala. $H - inani lomkhawulo wesisindo esiphelele ngenxa yephutha lokukala.

Isisindo esiphelele singaphansi kwenani elibekiwe ngenxa yephutha elibangelwe ukulinganisa. I-MTL - Izinga lokuphakelayo elikhiyiwe phakathi nesikhathi sokuphakela. I-TF - isikhathi esilinganiselwe.

Izinga lokuphakelayo elikhiyiwe i-MTL isaboniswa ngesisindo esiphelele ngomzuzwana ukuguquka kwe-K Ububanzi bubonisa: mtl=K(d±β*d1)/(1±te) Isikhathi sokuphakela Ukugeleza kokuphakelayo kwesango lamanzi MF, MF=10MT. Isikhathi sangempela se-TF=VA/MF yilesi: TE=TF+TD. Izinga lokugeleza elijwayelekile yilesi: mq=gq/tn Esikhathini ngasinye sohlelo lomjikelezo, isisindo esiphelele sezinto zokusetshenziswa sihlala sihlanganisiwe, futhi isisindo esiphelele se-tn ngaleso sikhathi i-t=0 ingalinganiswa ngokunembile.

Okwesihlanu, imiphumela. Kweminye imishini nemishini ehlukahlukene yokukala, ngenxa yokubophana kwezinto zokusetshenziswa, ukuguqulwa kwezinga lokushisa kweseli yomthwalo kubangela ukuthi isisindo se-tare sishintshe, ngaleyo ndlela kuncishiswe ukunemba kwesistimu, kodwa isisindo samakhanda amaningi siyasusa amaphutha anjalo, futhi kunzima ukuguqula ukuze kuncishiswe ukunemba kwesisindo. Isizathu silula kakhulu, ukulinganisa okunembile kwesilinganiso sokudla kwesisindo samakhanda amaningi kusekelwe ekwehlukeni kwesisindo esiphelele, hhayi ekwehlukeni kwesisindo esiphelele, ngakho-ke isisindo samakhanda amaningi sinethuba elibanzi kakhulu lokusetshenziswa ohlelweni lokuthuthwa kwezinto zokusetshenziswa zefayibha yamakhemikhali.
