Izindlela ezijwayelekile ezisetshenziswa yizikali zamakhanda amaningi

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

Emishinini yokukala, uhlobo luni lwesikali samakhanda amaningi olusetshenziswayo, kubalulekile ukucabangela zonke izici. Okulandelayo kuchaza isakhiwo sesikali samakhanda amaningi, ububanzi bokulinganisa, kanye nokukhethwa kwamazinga okunemba ngokuvamile okudingeka kucatshangelwe. 1. Ukukhethwa kwesakhiwo kanye nendlela yesikali samakhanda amaningi kuncike ezindinganisweni zemvelo zesakhiwo kanye nokusetshenziswa kwe-elekthronikhi.

Uma ufuna ukwenza izinto zikagesi eziklanywe ngendlela ephansi, ngokuvamile kufanele usebenzise izinzwa zohlobo lwe-cantilever beam kanye nezinzwa zohlobo lwe-wheel-spoke. Uma isilinganiso sesici somklamo singalawulwa ngokuqinile, ungakhetha inzwa yohlobo lwekholomu. Ngaphezu kwalokho, uma indawo yemvelo yezinhlelo zokusebenza ze-elekthronikhi inomswakama kakhulu futhi ibanda, futhi kunentuthu nothuli oluningi, kufanele ukhethe indlela enhle yokuvala; uma kunengozi yokuqhuma, kufanele usebenzise inzwa yokuvikela ukuphepha; uma usemgwaqweni ophakeme Emishinini esindayo, kufanele kucatshangelwe ukuphepha kanye nokuvikelwa kwamandla kagesi; uma isetshenziswa endaweni yemvelo eshisa kakhulu, kufanele kusetshenziswe i-multihead weiger enejazi lamanzi okupholisa; uma isetshenziswa ezindaweni ezibandayo kakhulu, kufanele kucatshangelwe ukukhetha i-multihead weiger enenzwa yedivayisi yokushisa. Ekukhetheni indlela, into eyodwa okufanele icatshangelwe ukuthi ukulungiswa kulula yini nokuthi izindleko, okungukuthi, uma imishini yokukala yehluleka, ukuthi izingxenye zokulungisa zingatholakala ngempumelelo nangokushesha.

Uma kungekho siqinisekiso, kusho ukuthi ukukhethwa kwendlela akufanele. 2. Ukukhethwa kobubanzi bokulinganisa Uma inani lokukala ledivayisi yokukala lisondele kakhulu kumthamo wesekethe esifushane seswishi, kulapho ukunemba kokukala kuphakeme khona. , isisindo sesondo, njll., ngakho-ke kunomehluko omkhulu kakhulu kuzinga lomkhawulo wesenzwa esetshenziswa yisoftware yesistimu yokukala ehlukile. Njengezinga elijwayelekile, kukhona: *Idatha ye-static yenzwa eyodwa Imishini yokukala: umthwalo oqinile (ipulatifomu yokukala, izitsha, njll.) + umthwalo oguquguqukayo (umthwalo ozolinganiswa) ≤Umthwalo olinganiselwe wesenzwa esetshenzisiwe X70%*Idatha ye-static yenzwa eminingi Imishini yokukala: umthwalo oqinile (ipulatifomu yokukala, izitsha, njll.) + umthwalo oguquguqukayo (umthwalo ozolinganiswa) ≤Kusetshenziswa umthwalo olinganiselwe wesenzwa X inani lezinzwa ezisetshenzisiwe X 70%, inkomba ka-70% iyengezwa uma kucatshangelwa izici ezifana nokudlidliza, umthelela, kanye nesisindo sesondo.

Kumelwe kuphawulwe ukuthi: okokuqala, amandla e-short-circuit ye-sensor kufanele asondele ngangokunokwenzeka enanini elisechungechungeni lomkhiqizo olujwayelekile lomkhiqizi, ngaphandle kwalokho, ukusetshenziswa kwemikhiqizo engeyona ejwayelekile akubizi nje kuphela, kodwa futhi akukwazi ukushintshwa ngemva komonakalo. Okwesibili, emishinini efanayo yokulinganisa, akuvunyelwe ukusebenzisa izinzwa ezinamakhono ahlukene e-short-circuit, ngaphandle kwalokho, isofthiwe yesistimu ayikwazi ukusebenza ngokujwayelekile. Okwesibili, ukukubeka ngokusobala, umthwalo oshintshayo (umthwalo okudingeka ulinganiswe) ubhekisela emthwalweni wangempela osetshenziswa ku-sensor. Uma inani lamandla lidluliselwa kusuka epulatifomu yokulinganisa kuya ku-sensor, kukhona inhlangano yokuphindaphinda kanye nokunciphisa (njengenduku). isofthiwe yesistimu ye-lever), izingozi zayo kufanele zicatshangelwe.

3. Ukukhethwa kokunemba Ukukhethwa kwezinga lokunemba kwesisindo samakhanda amaningi kufanele kukwazi ukucabangela imithethonqubo ezingeni lokunemba kwemishini yokukala, uma lo mthethonqubo ungacatshangelwa. Okusho ukuthi, uma inzwa enobubanzi bokulinganisa obungu-2500 ingahlangabezana nezidingo, ungasebenzisi ububanzi bokulinganisa obungu-3000. Uma kusetshenziswa izindlela eziningana ezifanayo emishini yokukala, lapho ama-inductor anamandla afanayo okujikeleza okufushane exhunywe ochungechungeni, isizathu sokuphambuka okuphelele yi-Δ, khona-ke: Δ=Δ/n1/2(2—12) Phakathi kwazo: Δ: isizathu sokuphambuka kobubanzi bezinzwa ngazinye; n: inani lezinzwa.

Ngaphezu kwalokho, imishini yokulinganisa kagesi ngokuvamile yakhiwa izingxenye ezintathu ezinkulu, okuyizinzwa zesisindo, izibonisi zesisindo kanye nezingxenye zemishini yemishini. Uma inani lephutha lesofthiwe yesistimu lingu-1, isizathu (Δ) sokuphambuka okuphelele kwesisindo samakhanda amaningi, okungenye yezingxenye ezibalulekile ze-electronics ezingezona ezenzakalelayo, ngokuvamile siyingxenye engu-0.7 kuphela. Ngokusekelwe kulokhu kanye nesibalo (2--12), akunzima kakhulu ukukhetha ukunemba kwenzwa okudingekayo.

4. Kufanele kufezwe kanjani ezinye izidingo ezikhethekile? Kweminye imishini yokukala, kungase kube nemithethonqubo eyingqayizivele. Isibonelo, esikalini sesitimela, ukuguqulwa kwe-elastic kwe-multihead weigher kulindeleke ukuthi kube kuncane, ukuze ipulatifomu yokukala ibe ngaphansi kwesimo sokukala. Ukususwa okuncane kunciphisa ukushaqeka nokudlidliza lapho amaloli amakhulu engena futhi ephuma epulatifomu yokukala. Ngaphezu kwalokho, lapho kwakhiwa imishini yokukala enamandla, akunakugwenywa ukubheka imvamisa yemvelo ye-multihead weigher evame ukusetshenziswa, ukuthi kungenzeka yini ukucabangela amalungiselelo okulinganisa okunembile kwamandla. Le pharamitha eyinhloko ayifakwanga ohlwini lomkhiqizo jikelele.

Ngakho-ke, uma ufuna ukuqonda kahle le pharamitha yokusebenza, kufanele uthintane nomenzi ukuze uvimbele amaphutha.
