IV. Olunye uchungechunge lwe-VFD
Ngaphezu kwalolu chungechunge olungenhla, i-INVT iphinde yethula izinhlobonhlobo zezinye izinhlobo zemikhiqizo ye-VFD, njengochungechunge lwe-GD20, uchungechunge lwe-ES840, njll. Le mikhiqizo nayo inezici zokusebenza kahle kakhulu nokonga amandla, ukulawula okunembile, ukugcinwa okulula nokuvikela ukuphepha, futhi ifanele izinhlobo ezahlukene zamamotho e-AC nezinhlelo zokulawula.
Imikhiqizo yochungechunge lwe-INVT VFD: Ukuhola isahluko esisha ku-industrial drive

Imikhiqizo yochungechunge lwe-INVT VFD iyisizukulwane esisha samadrayivu ashintshashintshayo athuthukiswe ngokucophelela yi-INVT ngokusekelwe eminyakeni engaphezu kweshumi yolwazi oluqoqiwe embonini ye-crane kanye nobuchwepheshe bokulawula obuthuthukisiwe. Le mikhiqizo ihlanganisa ingcebo yemisebenzi yokulawula ekhethekile yemboni yokuphakamisa kanye nemisebenzi ye-torque ephephile (i-STO), futhi ingasetshenziswa kabanzi kuma-cranes ahlukahlukene emikhakheni ehlukene njengamachweba, amafekthri, izindawo zokwakha kanye nezimayini, okubonisa ukusebenza okuhle kakhulu kokulawula, imisebenzi ebanzi yokuvikela ukuphepha namandla okwandisa avumelana nezimo.

Ibanga lamandla lemikhiqizo yochungechunge lwe-INVT VFD libanzi, limboza u-1.5~500kW we-AC 380V (-15%)~440V (+10%) kanye no-22~630kW we-AC 520V (-15%)~690V (+10%). Lokhu kubenza bakwazi ukuhlangabezana nezicelo zezimboni ezinosayizi nezidingo ezahlukene.

Mayelana nokusebenza, uchungechunge lwe-INVT VFD lunezici ezimbalwa eziphawulekayo. Okokuqala, banamandla okukhipha i-torque ye-low-frequency, ekwazi ukunikeza i-torque engu-0Hz/200% (i-torque elinganiselwe) kumodi yokulawula i-vector (FVC), kanye ne-0.5Hz/150% (i-torque elinganiselwe) kumodi yokulawula i-vector yesikhala. Lokhu kwenza i-crane isebenze kahle nangempumelelo ngaphansi kwezimo ezihlukene zokulayisha.

Okwesibili, uchungechunge lwe-INVT VFD lunokuguquguquka okuhle kakhulu komthwalo. Ngokusebenzisa ama-algorithms okulawula athuthukisiwe, bangakwazi ukulungisa ngokuguquguqukayo i-torque yokuphumayo ngokuya ngezimo zokulayisha, baqinisekise ukuthi i-crane inganikeza ukunethezeka okuhle kakhulu lapho yehliswa noma ilayishwa.

Ngaphezu kwalokho, uchungechunge lwe-INVT VFD luphinde lube nemisebenzi ehlukahlukene ekhethekile yezicelo ze-crane. Isibonelo, asekela ukulawulwa kwamahhala kwe-eddy yamanje yama-tower cranes, angamisa ngokushesha amabhuleki ahlehlayo, afinyelele ukushintshwa okushesha nokuhlehla kanye nokuma kokushuna kahle kwesivinini esiphansi. Ngasikhathi sinye, bangakwazi futhi ukulungisa i-flux kazibuthe ngokuya ngezimpawu zama-conical rotor motors, bafinyelele ukukhululwa kwamabhuleki okusheshayo nokulawula ukuvala shaqa, benze lula izinyathelo zokuthumela futhi baqinisekise ukuphepha kwemishini.

Mayelana nokuphepha, uchungechunge lwe-INVT VFD nalo lusebenza kahle. Bahlanganisa umsebenzi wokuqinisekisa itorque ukuze kuqinisekiswe ukusebenza okuphephile nokushelelayo ngemva kokusungulwa kwetorque. Ngasikhathi sinye, baphinde basekele ukusetshenziswa kokukhethwa kwesiqondisindlela sokuqala kanye nokukhetha amabhuleki ukuya phambili nokuhlehlisa ukushintsha ukuze kuhlangatshezwane nezidingo ezahlukene zokuqalisa. Ngaphezu kwalokho, uchungechunge lwe-INVT VFD luphinde lube nemisebenzi efana nokuvikela umkhawulo ophezulu naphansi kanye nokuvikelwa komkhawulo wokunciphisa izinga eliphezulu naphansi, okungakhawulela i-crane ukuthi isebenze ngaphakathi kwebanga elicacisiwe, iqinisekise ukuphepha kanye nokwandisa indlela yokuvala ukuze kuthuthukiswe ukusebenza kahle kwemishini.

Kuhle ukusho ukuthi uchungechunge lwe-INVT VFD luphinde lube nokuvikelwa okulwa nokuguquguquka. Basebenzisa i-algorithm yokulawula i-sensorless anti-sway control, engalungiswa kalula futhi ivumelane nezimo eziguquguqukayo ukuze zivumelane nezidingo zokulawula i-anti-sway yama-cranes ahlukahlukene. Ukwengeza, baphinde babe nomsebenzi wokuvikela izintambo okuxekethile ukugwema ukuphakamisa isivinini, ukwehluleka ukusheshisa kanye nezingozi zokuphepha esimweni sezintambo ezixegayo.

Mayelana nokonga amandla nokuvikelwa kwemvelo, uchungechunge lwe-INVT VFD nalo lusebenza kahle. Banganciphisa ukusetshenziswa kwamandla ngokulawula kahle isivinini namandla emoto. Uma kuqhathaniswa namadrayivu ezimoto endabuko, uchungechunge lwe-INVT VFD lungalungisa ngokuzenzakalelayo isivinini namandla emoto ngaphansi kwemithwalo ehlukene yokusebenza, ngaleyo ndlela kuzuze isilinganiso esiphezulu sokusebenza kahle kwamandla. Ngesikhathi esifanayo, aphinde abe nomsindo omncane nokudlidliza, futhi abe nomthelela omncane endaweni ezungezile.

Ngokuvamile, imikhiqizo yochungechunge lwe-INVT VFD isiphenduke amandla abalulekile emkhakheni wokushayela ezimbonini ngokusebenza kwawo okuhle kakhulu, izinkambu ezibanzi zohlelo lokusebenza kanye nezici ezivelele zokonga amandla kanye nezici zokuvikela imvelo. Kungakhathaliseki ukuthi kusembonini ye-crane noma kwezinye izimboni, imikhiqizo yochungechunge lwe-INVT VFD inganikeza abasebenzisi izixazululo ezisebenzayo, ezithembekile neziphephile zokushayela. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwanda okuqhubekayo kwezinkambu zezicelo, imikhiqizo yochungechunge lwe-INVT VFD izodlala indima ebaluleke kakhulu ekuthuthukisweni kwezimboni esikhathini esizayo.
