Ukusetyenziswa komsebenzi wokumisa ochanekileyo we-Danfoss FC51 inverter
Abathengi bahlala befuna oomatshini bemizi-mveliso kunye nezixhobo, ezinje ngoomatshini bokupakisha ngokuthe nkqo, oomatshini bokunkonkxa, kunye nesixhobo sokwenza iimoto ezincinci, ukumisa ngokuchanekileyo umatshini wokuphotha kwindawo ethile xa unikwe amandla. Ngenxa yokhuphiswano olumandla lwemarike, bakwafuna izisombululo ezonga imali ukuze bafezekise oku kumisa ngokuchanekileyo.
Ii-inverters ze-Danfoss FC51 series zibonelela ngendawo yokupaka echanekileyo eyakhelweyo ehlangabezana nezi mfuno. Ngokusebenza kwabo okukhethekileyo kwe-braking kunye namaxabiso akhuphisanayo, baye bavela njengokhetho olufanelekileyo kubathengi, banikezela iziphumo ezifanayo kwii-inverters eziphezulu.
Ukwenza umzekelo, cinga ngesicelo sokumisa esichanekileyo samva nje esiphunyezwe yiShanghai Xinling kumthengi. Ubume bomatshini buboniswe kuMfanekiso 1.
Izinzwa zokubona indawo zifakwe kwiindawo eziphezulu kunye nezisezantsi zomtshini wokuphotha, kwaye i-spindle motor reducer inomlinganiselo wokunciphisa we-1:10. Ukucinga ukuba i-motor isebenza kwi-62Hz, kuthatha malunga ne-333ms ukuba i-spindle igqibe ujiko olunye, ngokusekwe kwisantya esiqikelelwayo se-1800rpm.
Nantsi indlela umsebenzi wokumisa ochanekileyo osebenza ngayo:
Emva kokufumana umyalelo wokumisa, umlawuli ufumanisa umqondiso kwi-sensor 1 kwaye ngokukhawuleza ulungelelanise i-inverter's output frequency setting ukuya kwi-35Hz ngonxibelelwano. Oku kubangela ukuba injini yehle ukusuka kwi-62Hz ukuya kwi-35Hz ngaphakathi kwesiqingatha sotshintsho, okanye i-165ms.
Xa umlawuli efumana umqondiso kwi-sensor 2, iyancipha ngakumbi isantya semoto ukuya kwi-7Hz ngendlela efanayo. Enkosi ngomsebenzi ogqwesileyo we-FC51, ezi nkqubo zimbini zokuthoba ziphunyezwa kakuhle nangokuzinzileyo.
Emva kokufumana isignali kwi-sensor 1 kwakhona, umlawuli unqamula ngokukhawuleza i-terminal 33 ye-inverter, ebangela ukuba i-logic yayo isebenze ngokuchanekileyo. Esi senzo simisa intambo yokusonta ngesantya esiphezulu, ukuphumeza ukuphinda okukhethekileyo kwendawo yokumisa ukuchaneka.
Gcina useto olusisiseko lwefektri kwezinye iiparamitha ezinganxulumananga. Kufuneka kuqatshelwe ukuba eyona ndlela ichanekileyo yokumisa inverse logic yeFC51 inokusebenzisa iterminal 33 kuphela.
