Ngophuculo oluqhubekayo lweemfuno zemveliso ye-crane yokusebenza kwesantya solawulo lwesantya, iindlela eziqhelekileyo zolawulo lwesantya secrane ezifana ne-rotor ejikelezayo asynchronous motor rotor uthotho lokumelana nesantya, ukulawulwa kwesantya solawulo lwe-tyristor stator kunye nolawulo lwesantya se-cascade lunezi zinto zingalunganga zilandelayo: i-rotor ejikelezayo i-asynchronous motor inamakhonkco omqokeleli kunye neebrashi, ezifuna ukugcinwa rhoqo. Ukungaphumeleli okubangelwa amakhonkco abaqokeleli kunye neebrashi zixhaphake kakhulu. Ukongeza, ukusetyenziswa kwenani elikhulu leelayidi kunye nabafowunelwa kukhokelela kwisixa esikhulu sokugcinwa kwendawo, isantya esiphezulu sokungaphumeleli kwenkqubo yokulawula isantya, kunye nezalathisi zobugcisa ezihlwempuzekileyo zenkqubo yokulawula isantya, engakwaziyo ukuhlangabezana nayo. iimfuno ezikhethekileyo zemveliso yoshishino.
Usetyenziso olubanzi lwetekhnoloji yokulawula isantya sesantya se-AC kwicandelo leshishini libonelela ngesisombululo esitsha solawulo lwesantya esikhulu kunye nomgangatho ophezulu weekhrane eziqhutywa yi-AC asynchronous motors. Inezalathisi zokulawula isantya esiphezulu sokusebenza, inokusebenzisa i-squirrel cage asynchronous motors enesakhiwo esilula, ukusebenza okuthembekileyo kunye nokugcinwa okufanelekileyo, kwaye iyasebenza kwaye igcina amandla. Isiphaluka sayo sokulawula i-peripheral silula, umsebenzi wokulondoloza uncinci, imisebenzi yokukhusela kunye nokubeka iliso igqityiwe, kwaye ukuthembeka kokusebenza kuphuculwe kakhulu xa kuthelekiswa nenkqubo yendabuko yokulawula isantya se-AC. Ke ngoko, ukusetyenziswa kwe-AC yokulawula isantya sokutshintsha kwesantya yeyona nto iphambili kuphuhliso lwetekhnoloji yokulawula isantya se-crane AC.
Emva kokuba itekhnoloji yokulawula isantya sesantya se-AC isetyenzisiwe kwiikhreyini, xa kuthelekiswa nenkqubo yokulawula isantya se-asynchronous motor rotor esetyenziswa ngokubanzi kwintengiso, inokuzisa ezi zibonelelo zoqoqosho zilandelayo kunye nokhuseleko kunye nokuthembeka:
(1) IiCranes ezisebenzisa itekhnoloji yokulawula isantya sesantya se-AC zinenzuzo yokuma ngokuchanekileyo ngenxa yeempawu zomatshini wemoto eqhutywa sisiguquli samaza, kwaye aziyi kuba nento yokuba isantya semoto sitshintsha kunye nomthwalo weekhreyini zemveli, ezithi inokuphucula imveliso yokulayisha kunye nokukhulula imisebenzi.
(2) I-crane ye-frequency eguquguqukayo ihamba kakuhle, iqala kwaye ibhubhise kakuhle, kwaye ukungcangcazela kunye neempembelelo zomatshini wonke ziyancipha kakhulu ngexesha lokukhawuleza kunye nokunciphisa ngexesha lokusebenza, okuphucula ukhuseleko kunye nokwandisa ubomi beendawo zomatshini ze-crane.
(3) I-brake yomatshini iyasebenza xa i-motor ikwisantya esiphantsi, kwaye ukuqhawuka kwe-hook engundoqo kunye netroli kugqitywe ngokuqhawula umbane, ngoko ke ubomi be-brake pad ye-brake mechanical bunokwandiswa kakhulu kwaye iindleko zokugcinwa ziyancipha. .
(4) I-squirrel cage ye-asynchronous motor enesakhiwo esilula kunye nokuthembeka okuphezulu isetyenziselwa ukubuyisela i-rotor ejikelezayo ye-asynchronous motor, ukuphepha ukusilela komonakalo wemoto okanye ukusilela ukuqalisa okubangelwa ukudibana okungalunganga ngenxa yokunxiba okanye ukubola komqokeleli weringi kunye nebrashi. .
(5) Inani labafowunelwa be-AC lincitshiswe kakhulu, kwaye isiphaluka esiphambili se-motor siphumelele ukulawula ukungabikho koqhagamshelwano, ukuphepha ukutshiswa kwe-contactor contactor ngenxa yokusebenza rhoqo kunye nomonakalo we-motor obangelwa ukutshiswa kwe-contactor contactor.
(6) Inkqubo yokulawula isantya se-AC eguquguqukayo inokulungelelanisa ngokuguquguqukayo isantya segiya ngalinye kunye nokukhawuleza kunye nexesha lokunciphisa ngokweemeko zendawo, okwenza i-crane eguquguqukayo iguquguquke ukuze isebenze kwaye ibe nokuguquguquka okulungileyo kwisayithi.
(7) Inkqubo yokulawula isantya se-AC ye-AC yinkqubo yokulawula isantya esiphezulu kunye nokusebenza okuphezulu kunye nokulahlekelwa kobushushu obuphantsi, ngoko igcina umbane omkhulu xa kuthelekiswa nenkqubo yokulawula isantya esidala.
(8) I-frequency converter inokhuseleko olupheleleyo, ukubeka iliso kunye nemisebenzi yokuzixilonga. Ukuba idityaniswe nolawulo lwe-PLC, inokuphucula kakhulu ukuthembeka kwenkqubo yokulawula i-electronic frequency crane.
