Kuleli phepha, isimiso kanye nendlela yokuqinisekisa i-metrological ye-multihead weiger yethulwa ngokuningiliziwe kusukela ezicini zokwakheka kanye nesakhiwo. I-multihead weiger ingumshini wokondla oqhubekayo onomsebenzi wokuqinisekisa i-metrological. Yakhelwe ngokusekelwe esimisweni esiyisisekelo sokulawula umonakalo wesisindo ngesikhathi somsebenzi, futhi isetshenziswa kabanzi ezinhlelweni zokuhlanganisa ngokuzenzakalelayo ekukhiqizeni. Amagama angukhiye: i-multihead weiger isimiso esiyisisekelo sokuqinisekisa i-metrological Enqubweni yokwakha ikhabhoni yebhizinisi, uhlelo lokuhlanganisa ngokuzenzakalelayo luyisofthiwe yesistimu yokusebenza ebaluleke kakhulu kanye nokuqinisekisa i-metrological, okulimaza kakhulu ikhwalithi kanye nenani lenkomba yokukhiqizwa kwe-carbon anodizing. Iqukethe i-multihead weiger kanye nezikali zebhande ze-elekthronikhi ezine (ethula igama).

Ngokusekelwe ocwaningweni oluqinile, imisebenzi esebenzayo kanye nocwaningo lwesayensi lwezikali ezintathu zamakhanda amaningi, umhleli unokuqonda okujulile nokuqonda kwesisikali samakhanda amaningi. Lapha, isihluthulelo ukwenza isingeniso esilula nesiningiliziwe sezimiso eziyisisekelo nezindlela zokubala zesikali samakhanda amaningi. Yabelana ngaso nabafana. 1. Ukwakheka kwesakhiwo Isikali samakhanda amaningi ngokuvamile sakhiwe izingxenye ezibalulekile njengesango lokugcina amanzi okuphakelayo, isililo sokukala, idivayisi yokuxuba, imishini yokudla, uhlaka lwekhadi lomsindo, inzwa yesisindo kanye nemishini yokulawula yokuqinisekisa ukulinganisa. 1. Isango lokugcina amanzi okuphakelayo Isango lokugcina amanzi okuphakelayo lisetshenziselwa ukondla i-weighhopper. Ama-valve esango, ama-valve ebhabhathane, ama-valve esango, njll. asetshenziswa kakhulu. Ngokuvamile, ukukhathazeka okuyinhloko ukuvalwa kwalo, ikhono lokuxhumanisa ukushintsha kwamandla, kanye nemingcele yokusebenza yokudla okusheshayo nokubushelelezi.

2. Isilo sokukala Isilo sokukala siyindlela yokukala izinto zokusetshenziswa. Ukukhethwa kwezinto zokusetshenziswa kufanele kucabangele ukumelana nokugqwala kanye nokumelana ne-alkali. Ingxenye yenqubo yonke yokulinganisa kufanele ibe cishe yi-10%. 3. Idivayisi yokuxuba Idivayisi yokuxuba isetshenziswa kakhulu ukusiza ukuthululwa kwezinto zokusetshenziswa ngokujikeleza okubi. Ngokuvamile yakhiwe yinjini elula yokushayela yomshini wengalo ophula i-arch one-spiral auger blade noma i-spike. Ngokusho kokujikeleza kwengalo ephula i-arch, kulula ukuvela. Izinto zokusetshenziswa zokugoba kanye nezimbobo zamagundane zingaphonswa kahle ezindaweni zokungena nezokuphuma. 1 Isango lokulondolozwa kwamanzi okondla 2． Isilo sokukala 3. Inzwa yesisindo 4 i-rack yamakhadi omsindo 5. Idivayisi yokuxuba 6 Imishini yokondla 4. Imishini yokondla Imishini yokondla isetshenziselwa ukukhipha izinto zokusetshenziswa ezine-fibrous ku-hopper yokukala. Ngokwezici zezinto zokusetshenziswa ezizothuthwa kanye nesicelo semvelo, ama-screw conveyors, ama-impeller feeders, i-feeder, i-belt feeder.

Eziningi zezicelo, i-screw conveyor ingcono kuneminye imishini yokudla evaliwe. Ayikwazi nje ukuthutha izinto zokusetshenziswa ngokulinganayo, kodwa futhi igweme ukundiza nokugeleza kwezinto zokusetshenziswa ezimpuphu. 5. I-rack yekhadi lomsindo I-rack yekhadi lomsindo iyindawo yokusekela yeminye imishini nemishini, futhi inzwa yesisindo ifakiwe kuyo. 6. Inzwa yesisindo Inzwa yesisindo iyingxenye ebalulekile yesisindo se-multihead weigher, futhi inzwa eqinile yokumelana ne-strain gauge isetshenziswa kakhulu, eguqula isignali yedatha yesisindo se-net yezinto zokusetshenziswa ibe isignali ye-elekthronikhi yokukhipha.

7. Imishini yokulawula ukuqinisekiswa kwe-Metrological Imishini yokulawula ukuqinisekiswa kwe-Metrological yakhiwe nge-dial yesisindo esinezinhloko eziningi ehlakaniphile ngokuphelele kanye nesistimu yokulawula ezenzakalelayo ezenzakalelayo ngokuphelele, esetshenziselwa ukwenza ukulawula nokuqinisekisa isivinini sokudla, umthamo wokuthutha, njll. Ngaphezu kwalokho, amachweba okungena nawokuphakelayo esisindo esinezinhloko eziningi ngokuvamile kufanele asebenzise ukuxhumana okuthambile okulwa nokungcola kanye nokuxhumana okungenamoya okungenisa umoya ukuqinisekisa ukuthi ukuxhumana phakathi kwe-hopper yokugcina kanye nemishini elandelayo akuvimbeli ukulinganisa. I-silo yokukala yesisindo esinezinhloko eziningi kanye nedivayisi yokudla elungisekayo efakwe ngaphansi kwayo kutholakala ku-sensor yesisindo exhunywe ku-rack yekhadi lomsindo.

2. Isimiso 1. Isimiso Njengoba kuboniswe esithombeni, isikali samakhanda amaningi siqeda ukuqinisekiswa kwe-metrological ngokwesimiso esiyisisekelo sokulawula umonakalo wesisindo ngesikhathi somsebenzi. Okokuqala, kala imishini yokudla kanye nesilo sokukala, qhathanisa isivinini sokudla esithile nesivinini sokudla esibekiwe ngokwesimo somonakalo wesisindo ngeyunithi ngayinye, bese ulawula imishini yokudla ukuze wenze isivinini sokudla esithile sihlangabezane ngokunembile nenani elibekiwe kusukela ekuqaleni kuze kube sekupheleni. , Kuyo yonke inqubo yokondla esikhathini esifushane, imishini yokondla ithembele emandleni okwenza izimpawu zedatha zokukhwabanisa zigcinwe phakathi nomsebenzi womsebenzi ngokwesimiso esiyisisekelo somthamo. Uhlelo lwe-Load spectrum 2. Inqubo yonke yokukala Isisindo sezinto zokusetshenziswa esilo sokukala siguqulwa sibe isignali ye-elekthronikhi ngokwenzwa yesisindo bese sithuthwa siye kusikali sokukala samakhanda amaningi. Isikali sokukala samakhanda amaningi sizofeza isisindo esibaliwe sezinto zokusetshenziswa kanye namanani omkhawulo aphezulu naphansi asethwe ngaphambilini wesisindo se ... Ukuze kuqhathaniswe futhi kuhlonzwe, ngokusho kokulawulwa kwe-PLC kwesango lokongiwa kwamanzi, ukufakwa kwesilo esikaliwe kuyaphazamiseka.

Ngaphezu kwalokho, idayari yokulinganisa isisindo samakhanda amaningi iqhathanisa isivinini sokudla esithile esilinganisiwe (ukugeleza kokulayisha okuphelele) nesivinini sokudla esihleliwe, futhi isebenzisa ukulungiswa kwe-PID ukulawula imishini yokudla, ukuze isivinini sokudla esithile silandele ngokunembile inani elihleliwe. Lapho isango lamanzi okuphakelayo livulwa ukuze kulayishwe izinto ku-hopper yokukala, isignali yedatha isetshenziselwa ukukhiya isivinini sokudla, futhi kwenziwa ukudla okunomthamo. Idayari yokulinganisa isisindo samakhanda amaningi ibonisa ulwazi ngesivinini sokudla esithile kanye nesisindo esiphelele sezinto zokusetshenziswa ezikhishwe. Umdwebo wesimiso sesekethe yokusebenza 3. Ukubalwa kwesivinini sokudla Isivinini sokudla se-multihead weiger (ukugeleza okuphelele kwezinto zokulayisha) yinani lomonakalo wesisindo esiphelele ngesikhathi seyunithi. Inani lomonakalo i-dt liyisilinganiso esinembile sesikhathi somjikelezo. Ijubane lokuphakelayo uma kuziwa ekuboniseni idayari yesisindo samakhanda amaningi lingabalwa ngefomula elandelayo ethi MT=n(d±β*d1)/(td±te) lapho u-d——Idayari yesisindo samakhanda amaningi ibonisa ulwazi futhi ikhombisa inani n——Inombolo yokushintsha kwenani lokubonisa ulwazi d1——Isixazululo sangaphakathi sesikrini sedayari yesisindo samakhanda amaningi siyinkomba yephutha ledatha, ngokuvamile i-β=O. 6td——Ukulinganiswa okunembile kwesikhathi somjikelezo te——Inkomba yokuphambuka kwesikhathi, ngokuvamile te=0.0014, isisindo esiphelele sibalwa ngesikhathi somjikelezo esiphelele esiningiliziwe, isisindo esiphelele se-Gq sesisindo se-multihead sakhiwe izingxenye ezimbili, okungukuqinisekiswa kokulinganiswa kokudayela kwe-multihead weiger kanye nesisindo esigciniwe se-VA kanye nesikali Isisindo esiphelele sezinto ezingakalinganiswa futhi zaqinisekiswa ngesikhathi sokudla kwe-silo esisindayo VDGq=VA+VDVA=(VH+￡H)-(VL-￡L)VD=MTL*tF lapho VH——Inani eliphezulu lomkhawulo wesisindo esiphelele ku-silo esisindayo VD——Inani eliphansi lomkhawulo wesisindo esiphelele ku-silo esisindayo ￡H——Isisindo esiphelele inani eliphezulu lomkhawulo elilinganisa ukuphambuka ￡L——Isisindo esiphelele inani eliphansi lomkhawulo elilinganisa ukuphambuka MTL——Isivinini sokudla esikhiyiwe tF ngesikhathi sokulayisha——Ijubane lokudla i-MTL evalelwe yisikhathi sokudla lisaboniswa ushintsho lolwazi lokubonisa isisindo se-K ngomzuzwana: I-MTL=K(d±β*d1)/(1±te) Isikhathi sokudla sincike ekugelezeni kokudla okuphelele MF, MF kwesango lokugcina amanzi okuphakelayo≈10MTtF=VA/MF Isikhathi somjikelezo esiphelele esiningiliziwe yilesi: te=tF+td Isilinganiso sokugeleza okuphelele yilesi: Mq=Gq/tn Ngokuqhubekayo kuhlanganisa isisindo esiphelele sesikhathi ngasinye somjikelezo, isikhathi t=0-- Isisindo esiphelele se-tn.

5. Isiphetho Kweminye imishini nemishini kagesi ehlukahlukene, ngokuvamile ngenxa yokubophana kwezinto zokusetshenziswa, ukushintsha kwezinga lokushisa kwenzwa yesisindo kubangela ukuthi isisindo se-tare sishintshe, okuholela ekunciphiseni ukunemba kwesofthiwe yesistimu, kodwa isisindo samakhanda amaningi siyasusa amaphutha anjalo, akulula ukushintsha izinga lokushisa kunciphisa ukunemba kwesisindo. Isizathu silula kakhulu, ukulinganisa isivinini sokudla kwesisindo samakhanda amaningi kusekelwe ekwehlukeni kwesisindo esiphelele hhayi isisindo esiphelele, ngakho-ke isisindo samakhanda amaningi sinethuba lokusebenzisa elijwayelekile kakhulu kusofthiwe yesistimu yokuthutha izinto zokusetshenziswa eziluhlaza ezinamathelayo.
