Abahlinzeki bempahla yokonga ikheshi bakukhumbuza ukuthi edolobheni lanamuhla elinezakhiwo eziphakeme, amakheshi angamathuluzi abalulekile ehhovisi noma izindawo zokuhlala. Nokho, amakheshi adinga ukulungiswa njalo ukuze agcine ukusebenza kwawo okuvamile nokuphephile.
Ukugcinwa kwe-elevator ngokuyinhloko ukugcina ukusebenza kwayo okuvamile. Ezimeni eziphuthumayo ezifana nokucisha kukagesi, imililo, njll., izisetshenziswa eziphuthumayo zekheshi ziyadingeka ukuze kusingathwe zona.
Isimiso sokusebenza sesisetshenziswa esiphuthumayo sekheshi
Ukutholwa kwamandla
Uma igridi yamandla yangaphandle ihlinzeka amandla ngokujwayelekile, isifunda sokutholwa kwamandla kwedivayisi ephuthumayo inikeza isignali evamile yokunikezwa kwamandla okokufaka kwe-AC. Iphakethe lebhethri locingo lishajwa ngokuzenzakalelayo ngesekhethi yokushaja ukuze kugcinwe amandla kagesi okusebenza. Isekhethi yokushaja inemisebenzi yokuvikela efana nokukhipha ishaja eningi, i-overcurrent, kanye nesekhethi emfushane.
Ukusebenza okuphuthumayo
Lapho ilifti ihlangabezana nokunqamuka kukagesi kanye nesistimu yokulawula ikheshi iyeka ukusebenza, isistimu yokulawula ye-DSP yedivayisi yezimo eziphuthumayo izobona ngokushesha isimo sekheshi futhi ivule ngokuzenzakalelayo ukuhlenga okuphuthumayo. Okokuqala, i-K1A ihileleke ukuze inqamule ukunikezwa kwamandla kagesi kusuka kugridi yamandla yangaphandle kuya kusiguquli sokulawula ikheshi futhi kwenziwe ukuhlangana kukagesi. Okulandelayo, hlola ukuphepha, izingidi zeminyango, namasekhethi okunakekela amakheshi, futhi unikeze amandla kuzinzwa zendawo yomnyango ukuze uthole isignali yokuleveli. Uma kujwayelekile, qala isiguquli samanje ukuze unikeze amandla ohlelweni lokulawula umnyango (umshini womnyango we-AC, umshini womnyango we-DC, umshini womnyango oshintshashintshayo). I-motor MD yokuvula umnyango ithola i-voltage edingekayo futhi ivula kokubili umnyango wemoto kanye nomnyango wehholo ngesikhathi esisodwa; Uma imoto yekheshi ingekho endaweni yeleveli, ukuxhumana okuvamise ukuvuleka kwe-relay kuyavalwa, futhi isiguquli se-DC sinikeza amandla kusekethe yebhuleki yokubamba. I-brake yokubamba iyavulwa, futhi ukuphuma kwe-voltage kusuka kumjikelezo we-inverter yezigaba ezintathu kunikezwa emshinini wokudonsa ngokuthintana okuvame ukuvuleka kwe-K2A, idonsa imoto ye-lifti ohlangothini oluthile. Imoto yekheshi ima endaweni esezingeni. Misa ukukhipha i-voltage ye-inverter yezigaba ezintathu bese uvala ibhuleki. Ngemva kokuvulwa komnyango wemoto nomnyango wehholo, abathintwayo boxhumana nabo bedivayisi yesimo esiphuthumayo kanye nokudluliselwa kwedatha konke kubuyiselwa kusimo ngaphambi komsebenzi ophuthumayo.
Ukukhiya okuphephile
Uma isistimu yokulawula ye-DSP yedivayisi yezimo eziphuthumayo inquma ukuthi ilifti iyeke ukusebenza ngenxa yephutha lesekhethi yokuphepha noma isekethe yokukhiya umnyango, ngokuya ngezidingo "zeMithetho Yokuphepha" yokusebenza kwekheshi, idivayisi ngeke ifakwe ekusebenzeni okuphuthumayo. Ngisho nangemva kokuba idivayisi yezimo eziphuthumayo isifakwe ekusebenzeni okuphuthumayo, amasignali esekethe yokuphepha kwekheshi kanye nesekhethi yokukhiya umnyango ahlala egadiwe. Uma noma iyiphi isignali yokuvikela isikhiqiziwe, ukusebenza kwezimo eziphuthumayo kuzonqanyulwa ngokushesha ukuze kuqinisekiswe ukuphepha nokwethembeka kwabagibeli nezinto zokusebenza zekheshi. Ngokufanayo, idivayisi yezimo eziphuthumayo ihlale iqapha umjikelezo wokugcinwa kwesistimu yokulawula i-elevator. Uma abasebenzi abalungisa ikheshi behlola ikheshi, inqobo nje uma inkinobho yokulungisa isacindezelwe, idivayisi izokhiya ngokuzenzakalelayo futhi ingafakwa ekusebenzeni okuphuthumayo.
Ukuphela kwesimo esiphuthumayo
Ngemva kokuba umsebenzi ophuthumayo usuqediwe, ukuxhumana phakathi kwedivayisi nezingxenye ezihlukahlukene zesistimu yokulawula ikheshi kuyanqanyulwa, futhi kusesimweni sokulinda esodwa, esingenawo umthelela ekusebenzeni okuvamile kwekheshi. Lapho ugesi wezigaba ezintathu we-AC ubuyiselwa, isekethe yokushaja yedivayisi yezimo eziphuthumayo izoshajwa kabusha ngokuzenzakalelayo iphekhi yebhethri.
Faka 'amabhande okuphepha' amaningi kumakheshi. Abathuthukisi abaningi neminyango yokuphatha izakhiwo ibintula ukutshalwa kwezimali okudingekayo kanye nokunaka odabeni lokunikezwa kwamandla okuthembekile kumakheshi. Ngenxa yokushoda kukagesi, abanye olayini endaweni yedolobha elikhulu basengase babe nemikhawulo ephuthumayo yendawo yesikhashana esifushane. Ngaphezu kwalokho, amandla ahlukahlukene angaphandle angabangela nokunqamuka kukagesi wendawo. Uma i-elevator ifakwe ugesi ophuthumayo, ingaqinisekisa ukusebenza okujwayelekile kwe-elevator uma kwenzeka ukuphuma kwamandla okuphuthumayo, kube lula ukudluliswa okuphephile kwabagibeli.
