Abahlinzeki bemishini yokonga i-Elevator bayakukhumbuza: ngokuthuthuka kokuya emadolobheni, isidingo samakheshi siyakhula, ezibalweni zokuhlola ukusetshenziswa kukagesi kwamahhotela, izakhiwo zamahhovisi, njll., ukusetshenziswa kukagesi we-elevator kubalwa ngaphezu kuka-17% ~ 25% wokusetshenziswa kukagesi okuphelele, okwesibili kuphela kugesi osetshenziswa umoya opholile, ongaphezu kokukhanyisa, ukuhlinzekwa kwamanzi, njll.
Njengamanje, ikheshi ihlukaniswe yaba "idla amandla" kanye "nohlobo lwempendulo" ethuthukisiwe izinhlobo ezimbili, amakhasimende ekuthengeni okusha kwekheshi, ingxenye yokukhethwa kwekheshi "yohlobo lwempendulo" iya ngokuya iba ngaphezulu. Umphumela wokonga amandla uhlobene namandla esikheshi, lonke uhlelo lwekheshi, uhlelo lokulinganisa lwekheshi, njll., lezi zinhlobo zezimo ezilandelayo zingcono ukonga amandla:
(1) Lapho i-lifti iphakeme, lapho ibhuleka njalo, konga amandla;
(2) uma ikheshi lifakwa lisha, yilapho i-inertia yemishini iba nkulu, ukonga kakhulu amandla;
(3) Lapho ikheshi lishesha kakhulu, lapho ibhuleka kaningi, konga amandla;
(4) Lapho ikheshi lisetshenziswa kaningi, lapho ibhuleka njalo, konga amandla.
Ukwamukela ubuchwepheshe bamandla kagesi athuthukile, ikhwalithi enokwethenjelwa nephephile, ukusebenza okuhlakaniphile, okulula asikho isidingo sokuthi amakhasimende enze noma yimuphi umsebenzi. Kunesevisi ephelele yewaranti yangemva kokuthengisa, ukuxazulula zonke izinkinga zamakhasimende.
Uhlolojikelele Lwesimiso Somkhiqizo
Njengoba izinga lokukhiqizwa kwesimanje liqhubeka nokukhula nezinga lokuphila kwabantu liqhubeka nokuba ngcono, ukuphikisana kokuphakelwa kukagesi nesidingo kuya kugqama kakhulu, futhi ikhwelo lokonga amandla liyakhula. Izibalo ezifanele zikhombisa ukuthi umthwalo kagesi wokudonsa udla ngaphezu kuka-70% wawo wonke amandla asetshenziswayo. Ngakho-ke, uhlelo lokudonsa kwezimoto lunokubaluleka okubaluleke kakhulu kwezenhlalo kanye nezinzuzo zezomnotho.
Kunezinhlobo ezimbili eziyinhloko zezindlela zokonga ugesi ohlelweni lwe-motor traction:
(1) ukuthuthukisa ukusebenza kahle kwesistimu yokudonsa kwezimoto, njengesiphephetha-moya, ukulungiswa kwejubane lephampu yamanzi kuyindlela yokonga amandla okuhloswe ngayo ukuthuthukisa ukusebenza kahle komthwalo, bese ugandaganda wekheshi emukela ukulungiswa kwesivinini sokuguqula ama-frequency ukuze athathe indawo yejubane lokulungisa i-asynchronous motor kuyisinyathelo sokonga amandla okuhloswe ngaso ukuthuthukisa ukusebenza kahle kwenjini;
(2) Amandla emishini (amandla amancane, amandla e-kinetic) emthwalweni onyakazayo aguqulwa abe ugesi (ugesi ovuselelekayo) ngesiphakeli samandla futhi abuyiselwe kugridi ye-AC ukuze asetshenziswe ezinye izisetshenziswa zikagesi eziseduze, ukuze uhlelo lokudonsa imoto ludle ugesi ovela kugridi ngesikhathi seyunithi, ngaleyo ndlela kufezwe injongo yokonga ugesi.
Ikheshi ngokwesibonelo ukwethula uhlobo lwesibili lomgomo wokonga amandla
Ngaphezu kwalokho, i-lift nayo iwumthwalo omncane womthamo, ukuze uhudule umthwalo ngokulinganayo, umthwalo odonswa ugandaganda wakhiwe ngendawo yabagibeli kanye ne-counterweight balance block, kuphela lapho isisindo segumbi lomgibeli singama-50% (abagibeli abangu-1 ton bokuphakamisa abagibeli bangabantu abangaba ngu-7), igumbi kanye ne-counterweight balance block kuyalingana, ngaphandle kwalokho, ibhalansi ye-counterweight izoba nekhwalithi ephansi, ngakho-ke ibhalansi ye-counterweight izoba nesisindo esibi. okukhiqizwa lapho ilifti isebenza.
Amandla emishini engeziwe ekusebenzeni kwekheshi (equkethe amandla amancane, amandla e-kinetic) aguqulwa abe ugesi we-DC ogcinwe ku-capacitor kumjikelezo we-DC we-frequency converter, ngalesi sikhathi i-capacitor ifana nedamu elincane, ugesi omningi ubuyela ku-capacitor, i-voltage ye-capacitor iphezulu, (njengezinga lamanzi le-ultra-high uma lingekho i-reservoir) gcina ugesi, uzokhiqiza ukwehluleka kwe-overvoltage, ukuze isiguquli semvamisa siyeke ukusebenza, i-elevator ayikwazi ukusebenza kahle.
Njengamanje, iningi lama-elevator okushintsha imvamisa yasekhaya asebenzisa indlela yokusetshenziswa kwe-resistor egcinwe ku-capacitor ukuvimbela ukugcwala kwe-capacitor, kodwa ukusetshenziswa kwamandla okuphikisayo akunciphisi ukusebenza kahle kohlelo kuphela, inani elikhulu lokushisa elikhiqizwe yi-resistor libuye lenze ibe mbi indawo ezungeze ikhabhinethi yokulawula ikheshi.
Indima yesiphakeli samandla ukubuyisela ngempumelelo ugesi ogciniwe ku-capacitor kugridi ye-AC ukuze usetshenziswe ezinye izisetshenziswa zikagesi. Umphumela wokonga amandla usobala kakhulu, futhi izinga elijwayelekile lokonga amandla lingafinyelela ku-21% ~ 46%. Ngaphezu kwalokho, ngenxa yesici sokushisa esingamelani nokushisa, izinga lokushisa lomshini liyehla, lingasindisa ukusetshenziswa kwamandla kwe-air conditioning yegumbi lomshini, ezimweni eziningi, ukonga ukusetshenziswa kwamandla okupholisa umoya kuvame ukuletha umphumela omkhulu wokonga amandla.
Esinye sezici eziyinhloko zohlobo olusha lwesiphakeli samandla uma kuqhathaniswa nezinye iziphakeli zamandla ekhaya naphesheya umsebenzi wempendulo yokulawula okuguquguqukayo kagesi.
Iziphakeli zamandla ezijwayelekile zisekelwe kusayizi we-inverter DC circuit voltage UPN ukuze kunqunywe ukuthi uzowuphakelwa yini ugesi, i-feed back voltage isebenzisa inani elingaguquki elithi UHK. Ngenxa yokuguquguquka kugesi wegridi, lapho inani le-UHK lilincane, lizokhiqiza impendulo engamanga lapho i-voltage yegridi iphezulu; Uma inani le-UHK likhulu, umphumela wempendulo wehla kakhulu (amandla agcinwe ku-capacitor asetshenziswa ukumelana kusengaphambili).
Uhlobo olusha lwesiphakeli samandla lisebenzisa ukulawula okuguquguqukayo kwe-voltage, okungukuthi, kungakhathaliseki ukuthi i-voltage yegridi ishintshashintsha kanjani, kuphela lapho amandla omshini we-elevator eguqulwa abe ugesi ku-DC circuit capacitor, uhlobo olusha lwesiphakeli samandla luzobuyisela ngesikhathi esifanele amandla okugcina ku-capacitor kugridi, ixazulule ngempumelelo amaphutha empendulo yokuqala yamandla.
Ngaphezu kwalokho, uhlobo olusha lwe-feeder yamandla lunomsebenzi wokuvikela ophelele kakhulu nomsebenzi wokunweba, ongasetshenziswa kokubili ukuguqulwa kwamakheshi akhona kanye nokusekelwa kwamakhabhinethi amasha okulawula ikheshi. Ikhabhinethi entsha yokulawula ikheshi isebenzisa uhlobo olusha lwesiphakeli samandla ukuze isebenze, hhayi nje kuphela engonga kakhulu ugesi, kodwa futhi ingathuthukisa ngempumelelo ikhwalithi yokufaka yamanje, ukuze kuzuzwe amazinga aphezulu okuhambisana okungenzeka.
Uhlobo olusha lwesiphakeli samandla lufanele amakilasi ahlukahlukene kagesi, i-220VAC, 380VAC, 480VAC, 660VAC, njll.
Ukuphila Komkhiqizo
Ngokusho kokutholwa, isiphakeli samandla singasebenza ngokuthembekile amahora angaphezu kuka-70,000. Okusho ukuthi, ilifti isebenza amahora angu-24 ngosuku, izinsuku ezingu-365 ngonyaka, futhi isiphakeli samandla singasetshenziswa ngokuqhubekayo iminyaka engaphezu kwengu-8 kuya kweyi-10. Ngenxa yokuthi ilifti inesimo sokulinda noma sokulinda, ayifani nesibani, isesimweni sokusebenza isikhathi eside.
