Ngokukhula okusheshayo kwemboni yezindlu ezithengiswayo, nayo iqhubekisele phambili ukuthuthukiswa komkhakha wamakheshi. Namuhla, ama-elevator abe ukucushwa okudingekayo kwezakhiwo eziphakeme kakhulu, ngaphezu kwesidingo semisebenzi eyisisekelo, abantu baphishekela ukuphepha nokunethezeka kwe-elevator, kodwa bambalwa abantu abakhathalela ukusetshenziswa kwamandla kwamakheshi, okwenza ama-elevator abe yimishini yesibili enkulu kunazo zonke edla amandla ezakhiweni eziphakeme kakhulu ngemva kokupholisa umoya.
Ukutadisha umlando wokuthuthukiswa kwe-elevator, singathola ukuthi uhlelo lokulawula i-elevator kusukela ekulawuleni kwe-DC kwasekuqaleni kuya ekulawuleni okungenasici kwamagnetic kwanamuhla, isinyathelo ngasinye sokuthuthukiswa kobuchwepheshe be-elevator sihambisana nokunciphisa ukusetshenziswa kwamandla ekheshi, kulo mbono, ukonga amandla kuyisiqondiso esingenakugwenywa sokuthuthukiswa kwekheshi. Kodwa-ke, indlela yokubhuleka esetshenziswa ikheshi yamanje iseyiyo ikakhulukazi ukubhuleka kokusetshenziswa kwamandla, ukuze amandla avuselelekayo akhiqizwa ikheshi adliwe ngokushisisa amabhuleki, okubangela ukulahleka kwamandla amaningi, okwandisa izinga lokushisa kwegumbi lomshini, okungaholeli nje ekumoshweni kwesibili kwamandla, kodwa futhi kuthinta ukusebenza okuvamile kwekheshi.
I-Athikili yesi-7 yoMthetho Wokuphepha Kwezisetshenziswa Ezikhethekile waseRiphabhulikhi Yabantu baseChina ibeka ukuthi izingxenye ezikhethekile zokukhiqiza, ukusebenza nokusetshenziswa kwazo kufanele zihambisane nalo Mthetho neminye imithetho neziqondiso ezifanele, kusungulwe futhi kuthuthukiswe uhlelo lwesibopho sokuphepha kwemishini ekhethekile nokonga ugesi, kuqinise ukuphepha kwemishini ekhethekile nokuphathwa okonga ugesi, kuqinisekiswe ukukhiqizwa, ukusebenza kanye nokusetshenziswa kwemishini ekhethekile ukuphepha, futhi kuhlangatshezwane nezidingo zokonga ugesi.
I-Elevator mechanical traction yonga amandla ugandaganda wohlobo lwekheshi, ngokudonsa intambo yensimbi yensimbi ohlangothini olulodwa ukuze uxhume imoto, uhlangothi olulodwa ukuxhuma idivayisi ye-counterweight, ukushayela imoto nokusebenza okuphikisayo phezulu naphansi. I-elevator tractor inegiya futhi ayinagiya.
Elevator Energy Saving Technology
Amagiya ogandaganda ajwayele ukushayelwa u-gearbox oshayela isondo elidonsayo, kanti u-gearbox ujwayele ukushayelwa igiya lomnenke, elinciphisa ngo-35:2. Awukho u-gearbox phakathi kukagandaganda ongenagiya, oxhaswe yi-AC permanent magnet synchronous motor, futhi isilinganiso esimazombezombe sivame ukuba ngu-2:1 noma 1:1.
Ngokombono we-elevator yokuhlaziya ukonga amandla, ugandaganda ongenagiya ungcono kunogandaganda oyigiya, kodwa uma kufanele usebenzise ugandaganda oyigiyelwe njengomthombo wamandla, sebenzisa ugandaganda onegiya eliphezulu. Ugandaganda olungiselelwe ngokohlobo lwayo oluyinhloko lokushayela uhlukaniswe ikakhulukazi izinhlobo ezi-3 zomnenke, igiya le-bevel kanye negiya leplanethi, ukusebenza kahle kokudluliselwa komnenke kuphansi kakhulu, cishe ngama-70% kuphela; Ukudluliswa kwegiya leplanethi kanye nokudluliselwa kwegiya le-bevel kunamandla aphezulu wokudlulisela, kungafinyelela ngaphezu kwama-90%, kodwa ngenxa yezidingo zawo zokunemba komshini wamagiya aphezulu kanye nezindleko eziphezulu, ngakho-ke ukusetshenziswa kwawo akubanzi.
Ngaphezu kwalokho, i-giared drive ingasebenzisa injini ehambisanayo kazibuthe, esebenza kahle kakhulu okungenani ngo-10% kune-AC asynchronous motor, ewukuguqulwa okonga amandla kogandaganda abakugiya.
Unomphela uzibuthe ugandaganda synchronous unezinzuzo ezingenakuqhathaniswa uma kuqhathaniswa nogandaganda oyigiya. Ugandaganda wokuvumelanisa uzibuthe waphakade awudingi ukudonsa amandla asebenzayo asuka kugridi, ngakho amandla awo aphakeme uma kuqhathaniswa; Unomphela uzibuthe ugandaganda synchronous awudingi ukuyenga uzibuthe, akukho ukulahlekelwa induction, ngenxa yokushisa okuphansi komhlaba, ukusebenza kahle okuphezulu, kungathuthukiswa ngo-20% kuya ku-40%. Ugandaganda ohambisanayo ozibuthe ozibuthe wamukela isilawuli se-rotor magnetic field directional vector, inesivinini esifanayo esihle kakhulu, izici zokulawula itorque njengemoto ye-DC, ukuqala kanye nokubhuleka kwamanje kuphansi kakhulu kune-induction motor, amandla emoto adingekayo namandla okuguqula imvamisa ayancishiswa.
Ziningi izindlela zokonga amandla ohlelweni lokulawula ikheshi, enye iwukonga amandla ngokulawulwa kwamafrikhwensi okuguquguqukayo, kanti enye iwukusebenzisa amadivaysi empendulo ukuze wonge amandla.
Imvamisa yegridi yamandla esetshenziswa e-China ingu-50HZ, lokho okubizwa ngokuthi ukulungiswa kwemvamisa eguquguqukayo yokonga amandla, imvamisa kubhekiselwa ekulungiseni isivinini esingaphansi kuka-50HZ, okungukuthi, ukulungiswa kwemvamisa ngaphansi kwemvamisa yesisekelo.
Emazingeni aphansi ngaphansi kokulungiswa kwejubane, okungukuthi, ukulungiswa kwejubane ngaphansi kwe-torque engaguquki, ngokwesimiso se-motor kagesi, kungaziwa ngu-T = 9.55P / n, lapho i-torque T ihlala ingashintshiwe, amandla P azoshintsha ngokushintsha kwejubane n, okungukuthi, lapho n inyuka, i-P izophinde ikhule, lapho i-n iyancipha, i-P nayo izokwehla.
Ekusebenzeni okujwayelekile kwe-elevator, ngokwenani labagibeli ku-cabin, umsebenzi ohambisanayo ungakhishwa yi-converter ye-frequency, okungukuthi, lapho inani labagibeli likhulu, ukuphuma kwe-frequency converter kukhulu, futhi uma inani labagibeli lincane, ukuphuma kwe-frequency converter kuncane, ngaleyo ndlela kugweme umcimbi wezimoto ezincane, ngaleyo ndlela kuzuzwe inhloso yokulondoloza amandla.
2. Ngokusebenzisa ukonga amandla edivayisini yempendulo, ngokomgomo wokonga amandla, ikheshi ekulayisheni ukukhanya phezulu, umthwalo osindayo phansi kanye nezinga eliphansi, amandla engeziwe (kuhlanganise namandla e-kinetic namandla angaba khona) aguqulwa abe ugesi ovuselelekayo ngokusebenzisa isiguquli sikagesi kanye nemvamisa, futhi sisetshenziswe ukumelana nokushisa, ukusetshenziswa njalo kuzoholela ekwandeni kwegumbi elifakwe umoya opholile, ukuze igumbi elipholile lifakwe umoya. Uma kungenjalo, izobangela izinga lokuhluleka kwekheshi ukuthi likhuphuke.
Ukuphakama kwesitezi sokusebenza, imvamisa yokusebenza kaningi, ukonga kakhulu kwamandla, kuthuthukisa kakhulu ukusetshenziswa kahle kukagesi. Ngokwezibalo, amandla asetshenziswa ku-akhawunti ye-elevator brake resistor angu-25% ~ 35% wengqikithi yokusetshenziswa kukagesi we-elevator, uma le ngxenye yamandla ingaphinda isetshenziswe futhi isetshenziswe kabusha, ingafinyelela inhloso yokonga ugesi.
Elevator Energy Saving Technology
Uchungechunge lwe-IPC-PFE lwamadivayisi okonga amandla okuphakamisa amandla akhiqizwa yi-Shenzhen Hexing Ga Energy Technology Co., Ltd. alikwazi nje ukunciphisa izinga lokushisa lomshini kuphela, kodwa futhi liphinde lithole ngempumelelo amandla avuselelekayo, noma libuyisele kugridi, noma linikeze ezinye izinto zokusebenza zikagesi (i-air conditioning, amakhompyutha, izibani zikagesi, njll.) ukuze wonge amandla egridi.
Ubuchwepheshe bokonga amandla kanye nokunciphisa ngokuqinisekile buzoba isiqondiso esibalulekile socwaningo lwesikhathi esizayo nokuthuthukiswa kwamakheshi, futhi buyoba ngomunye wabahamba phambili benqubomgomo kazwelonke "yokonga amandla nokunciphisa ukungcola".
