Isicelo seHitachi EasyDrive VFD kwii-Escalators

Njengoko ukusetyenziswa kwamandla kakuhle kunye nentuthuzelo yabakhweli ibaluleke ngakumbi kwiinkqubo zothutho zanamhlanje, itekhnoloji ye-variable frequency drive (VFD) iye yaba sisisombululo esithandwayo sokuphucula ii-escalator. Inkqubo ye-Hitachi EasyDrive VFD inika ulawulo lwesantya olukrelekrele, ukusetyenziswa kwamandla okuncitshisiweyo, kunye nokuthembeka okuphuculweyo kokusebenza kwezicelo zee-escalator.

Isisombululo soLawulo lwee-Escalator ezikrelekrele

Inkqubo yeHitachi EasyDrive VFD isebenzisa ii-infrared sensors ezifakwe kwiindawo eziphezulu nezisezantsi ze-escalator.

Xa umkhweli esondela okanye enyathela kwi-escalator, i-infrared sensor iyavulwa ize ithumele isignali kwi-EasyDrive VFD. I-inverter ikhawulezisa ngokukhawuleza i-escalator ukuya kwisantya sayo sokusebenza esimiselweyo, iqinisekisa ukuthuthwa okuthambileyo nokukhululekileyo.

Ngamaxesha apho izithuthi zabakhweli ziphantsi okanye zingahambi kakuhle, inkqubo itshintshela ngokuzenzekelayo kwisantya esiphantsi sokusebenza. Le ndlela yokulawula ekrelekrele inciphisa kakhulu ukusetyenziswa kwamandla ngelixa igcina ukulungela ukusetyenziswa kwabakhweli.

Kwinkqubo yokulawula enyukayo nehlayo, inkqubo yokulawula isebenzisa ukhuseleko oludibeneyo ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo. Kukwafakelwe nesithinteli sokuqhobosha ukuze kufunxwe amandla agqithisileyo aveliswayo ngexesha lokuthomalalisa umbane kunye nokuhamba usiya ezantsi.

Iingenelo eziphambili zeNkqubo ye-EasyDrive VFD

I-Torque Eqinileyo Yokuqala Enesantya Esiphantsi

Isebenza kwimodi yokulawula i-vector evulekileyo, i-EasyDrive VFD inika ukusebenza okugqwesileyo kwamaza aphantsi kunye nokuphendula ngokukhawuleza.

Kwisiqalo se-0.5Hz, i-drive inokufikelela kwi-150% ye-torque elinganisiweyo, ihlangabezana ngokupheleleyo neemfuno ezifunekayo zezicelo ze-escalator.

Ukuqalisa Okuthambileyo Kokhuseleko Oluphuculweyo

Umsebenzi wokuqalisa othambileyo owakhelwe ngaphakathi unciphisa ukunyuka kwamandla ombane ngexesha lokuqalisa kwemoto, unciphisa uxinzelelo lombane kwimoto nakwinkqubo yokubonelela ngombane.

I-Power Factor ephuculweyo

I-EasyDrive VFD isebenza njengomthwalo we-capacitive, inceda ukuphucula amandla emoto kunye nokunciphisa ilahleko zamandla asabelayo, nto leyo ekhokelela ekusebenzeni kakuhle kwenkqubo iyonke.

Ukhuseleko olupheleleyo

Le nkqubo ibandakanya imisebenzi emininzi yokukhusela, kuquka:

• · Ukhuseleko olugqithisileyo
• · Ukhuseleko lwe-overvoltage
• · Ukhuseleko lomthwalo ogqithisileyo
• · Ukhuseleko lobushushu obugqithisileyo
• · Imisebenzi yokukhupha i-alamu engalunganga

Ezi mpawu zinceda ekuqinisekiseni ukusebenza okuzinzileyo nokuthembekileyo kwee-escalator phantsi kweemeko ezahlukeneyo zokusebenza.

Ukunxiba Okunciphisayo KweeMechanical

Ii-escalator zemveli zihlala ziqhubeka nokusebenza ngesantya esiphezulu nokuba akukho bakhweli bakhoyo. Ngenkqubo ye-EasyDrive VFD, i-escalator isebenza ngesantya esiphantsi ngexesha lokungasebenzi, nto leyo enciphisa kakhulu ukuguguleka kweetyathanga, ii-sprockets, iibheringi, kunye nezinye izinto zoomatshini.

Oku akupheleli nje ekwandiseni ubomi benkonzo yezixhobo kodwa kukwanciphisa neendleko zokulungisa.

Iindlela Zokusebenza Eziguquguqukayo

Inkqubo ye-EasyDrive VFD ixhasa zombini ezi zinto:

• · Imo yokusebenza ngokuzenzekelayo
• · Imo yokusebenza ngesandla

Kwimeko yempazamo ye-VFD, inkqubo ingatshintshela ngokuzenzekelayo ekusebenzeni kwamandla rhoqo, ivumela i-escalator ukuba iqhubeke nokuthutha abakhweli kwaye inciphise ukuphazamiseka kwenkonzo.

Iimfuno zesicelo se-Escalator

Ii-escalator ezininzi zeHitachi zisebenzisa ii-motor ze-AC ezinesantya esinye kunye neenkqubo zothumelo eziqhutywa ziitsheyini. Ngokwesiko, ezi escalator zisebenza ngokuqhubekayo ngesantya esilinganiselweyo esimalunga ne-0.5 m/s, nokuba abantu bahamba ngesithuthi esingakanani na.

Le ndlela yokusebenza idla ngokubangela oku kulandelayo:

• · Ukusetyenziswa kwamandla aphezulu
• · Ukwanda kokuguguleka koomatshini
• · Ixesha lokuphila elinciphileyo lezinto

Ngokudibanisa inkqubo ye-EasyDrive VFD, ii-escalators zinokulungelelanisa isantya sokusebenza ngokwemfuno yomkhweli. Xa abakhweli bebhaqwa, i-escalator ikhawuleza kakuhle ukuya kwisantya sokusebenza esipheleleyo. Ngexesha lokungasebenzi, inciphisa isantya ngokuzenzekelayo, ifezekisa ukonga amandla kunye nokuphucula ubude bexesha lezixhobo.
