Njengoba ukusetshenziswa kahle kwamandla kanye nenduduzo yabagibeli kuba yinto ebaluleke kakhulu ezinhlelweni zesimanje zokuhamba, ubuchwepheshe be-variable frequency drive (VFD) sebuyisisombululo esidumile sokuthuthukiswa kwe-escalator. Uhlelo lwe-Hitachi EasyDrive VFD lunikeza ukulawula isivinini okuhlakaniphile, ukusetshenziswa kwamandla okuncishisiwe, kanye nokuthembeka okuthuthukisiwe kokusebenza kwezinhlelo zokusebenza ze-escalator.
Isixazululo Sokulawula I-Escalator Ehlakaniphile
Uhlelo lwe-Hitachi EasyDrive VFD lusebenzisa izinzwa ze-infrared ezifakwe kokubili ekufikeni okuphezulu nangaphansi kwe-escalator.
Uma umgibeli esondela noma enyathela i-escalator, inzwa ye-infrared iyavulwa bese ithumela isignali ku-EasyDrive VFD. I-inverter isheshisa i-escalator ngokushesha iye kwisivinini sayo sokusebenza esisethwe kusengaphambili, iqinisekisa ukuthuthwa okubushelelezi nokukhululekile.
Ngesikhathi lapho abagibeli behamba kancane noma bengenazo nhlobo izimoto, uhlelo lushintsha ngokuzenzakalelayo luye esivinini sokusebenza esiphansi. Leli cebo lokulawula elihlakaniphile linciphisa kakhulu ukusetshenziswa kwamandla ngenkathi ligcina ukulungela ukusetshenziswa abagibeli.
Ukuze kusebenze phezulu naphansi, uhlelo lokulawula lusebenzisa isivikelo esixhumene ukuqinisekisa ukusebenza okuphephile nokwethembekile. Kufakwe ne-resistor yokubhuleka ukuze imunce amandla amaningi akhiqizwa ngesikhathi sokunciphisa ijubane nokuhamba phansi.
Izinzuzo Eziyinhloko Zohlelo lwe-EasyDrive VFD
I-Torque Eqinile Yokuqala Esheshayo Esiphansi
Isebenza kwimodi yokulawula i-vector evulekile, i-EasyDrive VFD inikeza ukusebenza okuhle kakhulu kwemvamisa ephansi kanye nokuphendula okusheshayo.
Ekuqaliseni kwe-0.5Hz, idrayivu ingaletha i-torque efinyelela ku-150%, ihlangabezana ngokugcwele nezidingo ezidingekayo zezinhlelo zokusebenza ze-escalator.
Ukuqala Okuthambile Kokuvikela Okuthuthukisiwe
Umsebenzi wokuqalisa okuthambile owakhelwe ngaphakathi unciphisa ukukhuphuka kwamandla kagesi ngesikhathi sokuqalisa kwenjini, kunciphisa ukucindezeleka kukagesi kokubili kunjini kanye nohlelo lokuphakelwa kwamandla kagesi.
Isici Samandla Esithuthukisiwe
I-EasyDrive VFD isebenza njengomthwalo we-capacitive, isiza ekuthuthukiseni amandla e-motor futhi inciphise ukulahlekelwa kwamandla okusabela, okuholela ekusebenzeni kahle kwesistimu iyonke.
Ukuvikelwa Okuphelele Kokuphepha
Uhlelo luhlanganisa imisebenzi eminingi yokuvikela, okuhlanganisa:
- · Ukuvikelwa kokushisa okuphezulu
- · Ukuvikelwa kwe-Overvoltage
- · Ukuvikelwa kokulayisha ngokweqile
- · Ukuvikelwa kokushisa okweqile
- · Imisebenzi yokukhipha i-alamu yephutha
Lezi zici zisiza ukuqinisekisa ukusebenza okuzinzile nokuthembekile kwe-escalator ngaphansi kwezimo zokusebenza ezahlukahlukene.
Ukuncipha Kokugqokwa Kwemishini
Ama-escalator endabuko avame ukuqhubeka nokusebenza ngesivinini esigcwele ngisho noma kungekho abagibeli. Ngohlelo lwe-EasyDrive VFD, i-escalator isebenza ngesivinini esiphansi ngezikhathi zokungasebenzi, okunciphisa kakhulu ukuguguleka kwamaketanga, ama-sprocket, ama-bearings, nezinye izingxenye zemishini.
Lokhu akugcini nje ngokwandisa isikhathi senkonzo yemishini kodwa futhi kunciphisa nezindleko zokulungisa.
Izindlela Zokusebenza Eziguquguqukayo
Uhlelo lwe-EasyDrive VFD lusekela kokubili:
- · Imodi yokusebenza okuzenzakalelayo
- · Imodi yokusebenza ngesandla
Uma kwenzeka iphutha le-VFD, uhlelo lungashintshela ngokuzenzakalelayo ekusebenzeni kwemvamisa yamandla, okuvumela i-escalator ukuthi iqhubeke nokuthutha abagibeli futhi inciphise ukuphazamiseka kwesevisi.
Izidingo Zesicelo Se-Escalator
Ama-escalator amaningi e-Hitachi asebenzisa ama-motor e-AC anesivinini esisodwa kanye nezinhlelo zokudlulisa eziqhutshwa uchungechunge. Ngokwesiko, la ma-escalator asebenza ngokuqhubekayo ngesivinini esilinganiselwe esingaba ngu-0.5 m/s, kungakhathaliseki ukuthi abagibeli bahamba kangakanani.
Le ndlela yokusebenza ivame ukuholela ku:
- · Ukusetshenziswa kwamandla aphezulu
- · Ukwanda kokuguguleka kwemishini
- · Isikhathi sokuphila sengxenye esinciphile
Ngokuhlanganisa uhlelo lwe-EasyDrive VFD, ama-escalator angakwazi ukulungisa isivinini sokusebenza ngokuhlakanipha ngokwesidingo sabagibeli. Uma abagibeli betholakala, i-escalator ishesha kahle iye esivinini sokusebenza esigcwele. Ngesikhathi sokungenzi lutho, inciphisa isivinini ngokuzenzakalelayo, ifinyelele kokubili ukonga amandla kanye nobude besikhathi semishini obuthuthukisiwe.
Isiphetho
Uhlelo lwe-Hitachi EasyDrive VFD lunikeza ikhambi eliphumelelayo lokuthuthukisa ukonga amandla kwe-escalator kanye namaphrojekthi okuthuthukisa. Ngokusebenzisa ukulawula isivinini okuhlakaniphile, ukusebenza kokuqala okulula, izici zokuvikela eziphelele, kanye nezindlela zokusebenza ngokuzenzakalelayo, uhlelo luthuthukisa ukuphepha, induduzo yabagibeli, kanye nokusebenza kahle ngenkathi kunciphisa izindleko zokulungisa.
Ufuna izixazululo zesimanje ze-escalator, ukuthuthukiswa kwe-VFD, noma izingxenye ze-escalator ezishintshayo? I-YuanQi inikeza imikhiqizo ethembekile, ukwesekwa kobuchwepheshe obuchwepheshile, kanye nezixazululo ze-one-stop zamaphrojekthi e-escalator kanye ne-elevator emhlabeni jikelele.
