Eli phepha lichaza ingqikelelo esisiseko kunye nendlela yokubala yokubhaqwa komlinganiselo womlinganiso weentloko ezininzi

Umbhali: Smartweigh–Multihead Weighter

I-software ye-batching system software yinkqubo ebaluleke kakhulu yokulawula, ukulinganisa kunye nokufumanisa kwinkqubo yokwenziwa kwekhabhoni yenkampani yenkampani, enempembelelo enkulu kumgangatho weemveliso eziveliswayo kwaye zicutshungulwe nge-anodizing kwi-carbon factory. Ukuqulunqwa komlinganiselo (chaza igama). Ngokophononongo olunzulu, imisebenzi yokuziqhelanisa nentlalontle kunye nophando lwezenzululwazi lwezilinganisi ezintathu zeentloko ezininzi, ndinokuqonda okungaphezulu kunye nobuchule bobunzima beentloko ezininzi. Nali isitshixo sokwenza umlinganiselo olula kunye oneenkcukacha zeekhonsepthi ezisisiseko kunye neendlela zokubala zezilinganisi ezintathu zeentloko ezininzi. Yazisa kwaye usebenze nzima nomntu wonke. Ukwakhiwa kwesakhiwo sokuqala.

Ngokubanzi, i-multihead weigher yenziwe ngezinto ezingundoqo ezifana ne-sluice yokutya, i-emele yokulinganisa, isixhobo esishukumisayo, izixhobo zomatshini wokutyisa, i-rack, iseli yomthwalo kunye nokulinganisa kunye nokuvavanya izixhobo zokusebenza. Iihopper ezimbini ezinobunzima. IWeighing hopper kukufakelwa kwemathiriyeli ekrwada kubunzima bemathiriyeli ekrwada. Ukukhethwa kweemodeli zezinto eziluhlaza kufuneka kuthathelwe ingqalelo ukumelana nokubola kunye nokumelana ne-asidi. Umthamo wokulinganisa wezinto eziluhlaza ukhethwa ngokwesiphumo esipheleleyo sokutya kwimizuzu emi-3, kwaye ixesha lokutya kufuneka liphendule yonke inkqubo yokulinganisa. I-10% okanye kunjalo.

Okwesithathu kukuxuba oomatshini. Isixhobo sokuxhokonxa sisetyenziswa ikakhulu ukuncedisa ekutyisweni kwemathiriyeli ekrwada ngokungabi namanzi aneleyo. Ngokuqhelekileyo yenziwe yimoto yokuqhuba yengalo eyophukayo ene-spiral auger blade okanye amazinyo ezinzipho. Izinto eziluhlaza zomngxuma ziwela kakuhle ekungeneni nasekuphumeni. 4. Izixhobo zokutyisa.

Isixhobo sothutho sisetyenziselwa ukuthutha iikhemikhali ifayibha imathiriyeli ekrwada kwisikali sokulinganisela. Ngokweempawu zemathiriyeli ekrwada ekufuneka zithuthwe kunye nemeko yendawo yesicelo, i-screw conveyors, i-centrifugal impeller conveyors, kunye nebhanti yokuhambisa ingasetyenziswa. Kwiimeko ezininzi, i-screw conveyors yomelele kunabanye oomatshini bokutyisa abavaliweyo kwaye ayinakuthwala kuphela imathiriyeli ekrwada ngokulinganayo, kodwa ikwanqanda ukutshiza kunye nokukhukuliseka kwemathiriyeli ekrwada engumgubo. Eyesihlanu isakhelo senkxaso yekhadi lesandi sangaphandle.

Isakhiwo senzwa yomsindo ngumzimba wendawo yokuxhasa ezinye izixhobo zomatshini kunye nezixhobo zomatshini, kwaye iseli yomthwalo ifakwe kuyo. 6. Inzwa yokulinganisa Ubunzima beNet yinxalenye ebalulekileyo yokulinganisa i-multihead weigher. Ikhetha i-high-resolution resistance gauge sensor sensor, eguqula umqondiso wobunzima bomnatha wemathiriyeli ekrwada ibe ngumqondiso wedatha yesixhobo sombane ukwenzela imveliso. 7. Umlinganiselo kunye novavanyo lwezixhobo zokulawula.

Isixhobo sokulinganisa kunye nokulawula siqulunqwe yi-multihead weigher dial ehlakaniphile kunye nenkqubo yokulawula ngokuzenzekelayo, esetyenziselwa ukulawula nokulinganisa izinga lokuthutha izinto eziluhlaza kunye nomthamo wokuthutha. Ukongeza, izibuko lokutyisa kunye nezibuko lokutyisa le-multihead weigher kufuneka ngokubanzi ukhethe ukulandela ukungcola okuthambileyo kunye nokutywina uqhagamshelo oluthambileyo lokuqhuba ukuqinisekisa ukuba uqhagamshelo phakathi komgqomo wokugcina kunye nezixhobo ezilandelayo akukho lula ukuthintela ubungakanani. I-hopper enzima yi-multihead weigher, kwaye i-feeder adjustable ifakwe kwiseli yomthwalo egxininiswe kwisakhelo.

Okwesibini, umgangatho. Okokuqala, umgangatho. Uvavanyo lweMetroloji lusekwe kwingqikelelo esisiseko yokulawula iingozi zobunzima bomnatha kuyo yonke inkqubo yomsebenzi.

Okokuqala, linganisa izixhobo zomatshini wokusika kunye ne-hopper yokulinganisa, setha isantya sangempela sokusika ngokuhambelana nomonakalo wobunzima bobunzima ngexesha leyunithi, kwaye emva koko ulawule izixhobo zomatshini wokusika ukwenza isantya sangempela sokusika. Iiparamitha zokulawula zichanekile kwaye zihambelana, kwaye ngexesha elifutshane, izixhobo zomatshini wokusika zisebenzisa amandla okusebenzisana ngexesha lenkqubo yonke yokusika ukwenza iimpawu zokulawula ezigcinwe phakathi kunye nezigaba kamva zomsebenzi ngokuhambelana nombono osisiseko. yomthamo. Okwesibini kukulinganisa yonke le nkqubo. Ubunzima obunetha bezinto eziluhlaza kwi-hopper yokulinganisa buguqulwa bube zizixhobo zombane ngokobunzima benzwa, kwaye idatha ithunyelwa ngaphandle kwamacingo kwi-multihead weigher case. Ngokwahlukileyo, ngokolawulo lwe-PLC lwesango lamanzi lokutyisa, i-hopper yokulinganisa iyanqunyulwa.

Ukongeza, iphaneli yesixhobo kwinqwelo yokulinganisa ithelekisa ukulinganisa ngokuchanekileyo izinga lokutya langempela (ukuhamba kokuvula) kunye nesantya sokutya esisethiweyo, kwaye isebenzisa uhlengahlengiso lwe-PID ukuphumeza ukusebenza kwangempela koomatshini bokutya kunye nezixhobo, ukwenzela ukuba izinga lokutya langempela. inokulungiswa. Umlinganiselo wesondlo ulandelela ngokuchanekileyo ixabiso elisekwe kwangaphambili. Xa isango lokutya lamanzi livulwa ukuba lidle kwi-hopper yokulinganisa, isignali yedatha yokulawula ivala izinga lokutya, kwaye iqala ukutya kwe-volumetric. I-multihead weigher case ibonisa umxholo wolwazi wezinto ezingenayo neziphumayo, ubonisa izinga langempela lezinto ezingenayo neziphumayo, kwaye Ibonisa ulwazi malunga nobunzima obupheleleyo bezithako. Okwesithathu ngumlinganiselo ochanekileyo womlinganiselo wokutyisa.

Izinga lokutya (ukuhamba kokuvula) kwe-multihead weigher yi-net yomonakalo wexabiso lomonakalo ngexesha leyunithi, elibalwe ngokwethiyori ngefomula mt=dG/dt. Isantya esikhulu sokusika; ixabiso lomonakalo womnatha, o.k.t. i-dG ilinganisa ngokuchanekileyo ixesha dt. I-multihead weigher inokulinganisa ngokuchanekileyo izinga lokupasa ngokucinezela kunye nokubamba phantsi kwemeko ebonisiweyo.

mt=n(d±β*d1)/(t±t) Ifomula iyabalwa. I-d-multihead weigher dial ibonisa uluhlu. Ulwazi lwe-n-Display lubonisa inani leenguqu ezilinganisiweyo zomxholo wolwazi.

I-D1- Isisombululo sesikrini sesikrini sangaphakathi sepaneli yesixhobo kwisithuthi sokulinganisa ixabiso lesalathisi sephutha lokulinganisa, eliboniswa ngokubanzi ngu-β = O.6. I-TD - umlinganiselo ochanekileyo wexesha lenkqubo yokujikeleza. I-Te - ixabiso lesalathiso sesizathu sokurekhoda iimpazamo ngexesha lokurekhoda, ngokubanzi, te=0.001.

4. Bala ubunzima bubonke. Ubunzima obupheleleyo be-Gq kwixesha elipheleleyo lomjikelo we-multihead weigher inamacandelo amabini, angala uvavanyo lokulinganisa i-multihead weigher kunye ne-multihead weigher dial net weight VA, kunye ne-multihead weigher dial case net weight V engalinganiswanga isigaba sangaphambili. . gq=va+VD product=(imveliso+imveliso)-(imveliso-imveliso)-0CD=MTL*TF ubalo lwefomula.

I-VH- Ixabiso eliphezulu lomda wobunzima bobunzima ngaphambi kokulinganisa isitokhwe sendawo yokugcina impahla. Ixesha lonyaka - I-Net isinongo esisezantsi ixabiso elilinganiselweyo kumgqomo wokulinganisa. I-$H - ixabiso elilinganiselweyo kubunzima bomnatha ngenxa yempazamo yokulinganisa.

Ubunzima bomnatha bungaphantsi kwexabiso elichaziweyo ngenxa yempazamo ebangelwa kubunzima. I-MTL - Izinga lokutya okutshixiweyo ngexesha lokutya. TF - ixesha eliqikelelweyo.

Umyinge wesondlo esitshixiweyo i-MTL isaboniswa kubunzima bomnatha ngesekhondi nganye K kwiinguqu Uluhlu lubonisa: mtl=K(d)±β*d1)/(1±te) Ixesha lokutya Ukondla isango lamanzi ukuqukuqela kokutya MF, MF=10MT. Elona xesha lilonke le-TF=VA/MF lithi: TE=TF+TD. Umyinge wokuhamba komndilili ngu: mq=gq/tn Kwixesha lenkqubo yomjikelo ngamnye, ubunzima bobunzima bempahla ekrwada buqhubekeka bubonke, kwaye ubunzima betn bubonke ngexesha t=0 bunokulinganiswa ngokuchanekileyo.

Okwesihlanu, iziphumo. Kwezinye izixhobo ezahlukeneyo zokulinganisa kunye noomatshini, ngenxa yokudityaniswa kwezinto ezikrwada, ukuguqulwa kobushushu beseli yomthwalo kubangela ukuba ubunzima be-tare butshintshe, ngaloo ndlela kuncitshiswe ukuchaneka kwenkqubo, kodwa i-weigher ye-multihead iyazisusa ezo ziphene. Kunzima ukuguqula ukunciphisa ukuchaneka komlinganiso. Isizathu silula kakhulu, umlinganiselo ochanekileyo wesantya sokutya se-multihead weigher usekwe kumahluko wobunzima bomnatha, hayi umahluko wobunzima bomnatha, ngoko ke i-multihead weigher inethemba elibanzi kakhulu lesicelo kwinkqubo yothutho lwemichiza yefiber ekrwada.
