Ukusetshenziswa kokuma okunembile komsebenzi we-Danfoss FC51 inverter
Amakhasimende avame ukudinga imishini yezimboni kanye nemishini, njengemishini yokupakisha emile, imishini yokufaka amathini, nemishini emincane yokukhiqiza izimoto, ukumisa ngokunembile umshini wokuphotha umshini endaweni ethile lapho wehliswa amandla. Uma kubhekwa ukuncintisana kwemakethe okukhulu, baphinde bafune izixazululo ezibiza kakhulu ukuze bathole lokhu kumisa okunembayo.
Iziguquli zochungechunge ze-Danfoss FC51 zinikeza umsebenzi wokupaka onembile owakhelwe ngaphakathi ohlangabezana nalezi zidingo. Ngokusebenza kwawo okukhethekile kokubhuleka kanye namanani ancintisana kakhulu, avele njengenketho ekahle kumakhasimende, eletha imiphumela efanayo kuma-inverter asezingeni eliphezulu.
Ukuze ufanekise, cabangela uhlelo lokusebenza lwakamuva olunembayo lokumisa olusetshenziswe i-Shanghai Xinling kukhasimende. Isakhiwo semishini sikhonjiswe kuMfanekiso 1.
Izinzwa zokubona indawo zifakwa emaphethelweni aphezulu naphansi e-spindle yomshini, futhi isinciphisi se-spindle motor sinesilinganiso sokunciphisa esingu-1:10. Uma sicabanga ukuthi injini isebenza ku-62Hz, kuthatha cishe u-333ms ukuthi i-spindle iqedele ukuphenduka okukodwa, okusekelwe esilinganisweni sesivinini semoto esingu-1800rpm.
Nansi indlela umsebenzi wokumisa oqondile osebenza ngayo:
Lapho sithola umyalo wokumisa, isilawuli sithola isignali evela kunzwa 1 futhi ngokushesha silungise izilungiselelo zokuphuma kwemvamisa ye-inverter ibe ngu-35Hz ngokuxhumana. Lokhu kubangela ukuthi injini yehle isuka ku-62Hz iye ku-35Hz phakathi nengxenye yokuphenduka, noma ku-165ms.
Lapho isilawuli sithola isignali ku-sensor 2, siphinde sinciphise isivinini semoto siye ku-7Hz ngendlela efanayo. Ngenxa yokusebenza okuphezulu kwe-FC51 inverter, lezi zinqubo ezimbili zokuhlehlisa zifinyelelwa ngokushelela nangokuzinza.
Ngemva kokuthola isignali kusuka ku-sensor 1 futhi, isilawuli sinqamula ngokushesha i-terminal 33 ye-inverter, icupha umqondo wayo oqondile wokumisa umsebenzi. Lesi senzo simisa i-spindle ngesivinini esikhulu, sithola ukunemba okukhethekile kokuma kwendawo yokumisa.
Gcina izilungiselelo ezizenzakalelayo zefekthri ukuze uthole amanye amapharamitha angahlobene. Kufanele kuqashelwe ukuthi umsebenzi oqondile wokumisa okuphambene we-FC51 ungasebenzisa kuphela itheminali 33.
