Ngokuthuthuka okuqhubekayo komnotho kanye nokwenza ngcono okuqhubekayo kwamazinga okuphila abantu, isidingo samandla siya ngokuya sikhuphuka. Ngesikhathi esifanayo, izinkinga ezinjengokungcoliswa kwemvelo nokushintsha kwesimo sezulu nazo ziyanda. Ngokumelene nalesi sizinda, ukuthuthukisa ukusebenza kahle kokusetshenziswa kwamandla kanye nokunciphisa ukusetshenziswa kwamandla sekuphenduke izinselele ezivamile kuwo wonke amazwe. Imoto kazibuthe ehlala njalo iwuhlobo olusha, ukusebenza kahle okuphezulu, injini yokonga amandla, umphumela wayo wokonga udonse ukunaka okukhulu. Namuhla sibheka isimiso kanye nezinzuzo zamamotho kazibuthe ahlala njalo, futhi sabelana nawe ngamakesi amabili okonga amandla amamotho kazibuthe e-Minten aphansi-voltage unomphela emkhakheni we-metallurgy nokuvikelwa kwemvelo.
Isimiso esiyisisekelo semoto kazibuthe unomphela
I-Permanent magnet motor iwuhlobo lwenjini esebenzisa ukuxhumana phakathi kwendawo kazibuthe ekhiqizwe ngozibuthe baphakade kanye namandla kagesi ukuguqula amandla kagesi abe amandla emishini. Isakhiwo sayo esiyisisekelo sihlanganisa uzibuthe unomphela, i-stator kanye ne-rotor. Umazibuthe unomphela usebenza njengesigxobo kazibuthe senjini futhi uxhumana ne-current in the stator coil ngokusebenzisa inkambu yawo kazibuthe ukuze ukhiqize i-torque futhi udlulisele amandla omshini ku-rotor, eqaphela ukuguqulwa kwamandla kagesi kumandla omshini.
Uma kuqhathaniswa ne-motor induction yendabuko, injini yamagnetic unomphela inezinzuzo ezilandelayo:
1. Ukusebenza kahle okuphezulu: Izinjini zendabuko zokungenisa amandla zinamandla aphansi ngenxa yokuthi amandla kazibuthe akhiqizwa amandla amanje kukhoyili futhi kukhona ukulahlekelwa kokungeniswa. Ngenkathi indawo kazibuthe yemoto kazibuthe unomphela ihlinzekwa ngozibuthe baphakade, abangaguqula amandla kagesi abe amandla omshini ngempumelelo kakhudlwana. Ngokwezifundo ezifanele, ukusebenza kahle kwamamotho kazibuthe unomphela kukhuphuke cishe ngo-5% kuye kwangama-30% uma kuqhathaniswa nezimotho ezijwayelekile zokungenisa.
2. Ukuminyana kwamandla aphezulu: Amandla kazibuthe wemoto kazibuthe unomphela aphakeme kunalawo e-induction motor, ngakho anamandla aphezulu.
3. Ukonga amandla: Njengoba amamotho kazibuthe unomphela esebenza kahle kakhulu kanye nokuminyana kwamandla aphezulu, lokhu kusho ukuthi angakwazi ukukhipha amandla emishini engeziwe ngamandla okufaka afanayo ngevolumu nesisindo esifanayo, ngaleyo ndlela aqaphele ukonga amandla.
Ukushintshwa kwezinjini zokungeniswa kwe-asynchronous ezingasebenzi kahle ngama-motor kazibuthe ahlala njalo, kuhlanganiswe nokulungiswa kwezimo zokusebenza nokulawulwa kwemvamisa kwemishini esetshenziswa amandla endala nengasebenzi kahle, kungathuthukisa kakhulu ukusebenza kahle kwamandla kwemishini esebenzisa amandla, kanye nala macala angu-2 ajwayelekile okusebenza. ngezethenjwa.
1: iqembu eliseGuizhou reel motor transformation project
Septhemba 25, 2014 - Disemba 01, 2014, e-anhui mingteng uzibuthe unomphela wemishini yemishini ye-electromechanical co., LTD kanye neqembu e-guizhou imboni yefekthri yokudweba i-workshop yokudweba ucingo ngocingo isigaba 29 # ngqo emshinini wokudweba ucingo, 1 #, 2 #, 5 # reel motor energy tracking tracking record comparison, will anhui mingteng permanent magnet motor kanye nokusetshenziswa kwamanje kwama-inverter motors ukuze kusetshenziswe amandla ukuqhathanisa.
(1) Ukuhlaziywa kwethiyori ngaphambi kokuhlolwa kukhonjiswe kuThebula 1 ngezansi
Ithebula 1
(2) Izindlela zokulinganisa kanye nedatha yezibalo erekhodiwe futhi iqhathaniswe kanje
Ukufakwa kwemitha yamandla asebenzayo enezigaba ezintathu ezinezintambo ezine kanye nedivayisi yokulinganisa efakwe i-transformer yamanje, isilinganiso siwukuthi: imitha ephelele 1500/5A, No. 1 reel machine sub-meter 150/5A, No. 2, No. I-sub-meter engumshini we-reel engu-5 100/5A, idatha eboniswa kumamitha amane wokulandelela amarekhodi, ukuhlaziywa kwezibalo kungokulandelayo:

2:Iphrojekthi yokuvuselela abalandeli be-Centrifugal yenkampani enomkhawulo wokuvikela imvelo
Iphrojekthi ngomthethonqubo wejubane lokuguqula imvamisa, ukuze injini kazibuthe unomphela iqale kancane, futhi ekugcineni ifinyelele isivinini esilinganiselwe, isisombululo esiphelele semotor uzibuthe oziqalayo unomphela kufeni ye-centrifugal lapho inkinga yokuvumelanisa ibandakanyeka. Ngaphezu kwalokho, ayixazululi kuphela umthelela wemishini ku-fan centrifugal lapho i-motor iqala futhi inciphisa izinga lokuhluleka kwe-centrifugal fan, kodwa futhi ukusebenza kahle kwe-motor kuzothuthukiswa nakakhulu.
(1) Amapharamitha wemoto yokuqala engavumelanisi
(2) Amapharamitha ayisisekelo enjini yokuguqula imvamisa kazibuthe unomphela
(3): Ukuhlaziywa kokuqala kwezinzuzo zokonga amandla
Abalandeli, amaphampu njengemboni, ezolimo, impilo yemishini evamile, enenani elikhulu lezinhlelo zokusebenza, ukusetshenziswa kwezici ezihlukahlukene, ukusetshenziswa kwayo kwamandla emoto nakho kukhulu. Ngokusho kwezibalo, ukusetshenziswa kwamandla kwesistimu yezimoto kungaphezu kuka-60% wokukhiqiza ugesi kazwelonke, kuyilapho abalandeli, amaphampu abalelwa ku-10.4%, 20.9% wokukhiqiza ugesi. Ngenxa yomthamo kanye nezizathu zenqubo, ukulawulwa kwesistimu kubuyele emuva, iningi labalandeli namaphampu alawulwa yi-mechanical interception, ukusebenza kahle okuphansi, ngaphezu kwengxenye yamafeni namaphampu imithwalo ikhona ngamazinga ahlukahlukene emfucumfucu kagesi, ukunikezwa kwamandla okushubile namuhla, ukunciphisa imfucuza, ukonga amandla kagesi kube yinto ehamba phambili.
U-Anhui Mingteng ubelokhu ezibophezele ekukhiqizeni nasekucwaningeni nasekuthuthukisweni kwama-motor kazibuthe asebenza kahle futhi anobungani kwemvelo, asetshenziswa kabanzi emikhakheni yezimboni zensimbi nensimbi, izimayini zamalahle, izinto zokwakha, amandla kagesi, i-petroleum, imboni yamakhemikhali, irabha, insimbi, izindwangu nokunye. Amamotho kazibuthe ahlala unomphela ane-voltage ephansi ebangeni lomthwalo ongu-25% -120%, uma kuqhathaniswa nencazelo efanayo ye-asynchronous motor anokusebenza kahle okuphezulu, ububanzi bokusebenza komnotho okubanzi, anomphumela obalulekile wokonga amandla, abheke ngabomvu amabhizinisi amaningi ukuqonda amamotho kazibuthe unomphela. , ukusetshenziswa kwamagnetic motors unomphela.
