Ukwenyuka kwezinga lokushisa kuwukusebenza okubaluleke kakhulu kwenjini, okubhekisela enanini lokushisa elijikayo elingaphezu kwezinga lokushisa elizungezile ngaphansi kwesimo sokusebenza esilinganiselwe semoto.Enjinini, ingabe izinga lokushisa lihlobene nezinye izici ekusebenzeni kwemoto?
Mayelana ne-Motor Insulation Class
Ngokusho kokumelana nokushisa, izinto zokufakelwa zihlukaniswe ngamabanga angu-7: Y, A, E, B, F, HC, futhi amazinga okushisa ahambisanayo asebenza ngokweqile angama-90 ° C, 105 ° C, 120 ° C, 130 ° C, 155 ° C, 180°C nangaphezulu kuka-180°C.
Okubizwa ngokuthi izinga lokushisa elilinganiselwe lezinto zokuvikela i-insulating libhekisela enanini lokushisa elihambisana nendawo eshisa kakhulu ekufakweni okumazombezombe ngesikhathi sokusebenza kwenjini phakathi nesikhathi sokuphila somklamo.
Ngokusho kokuhlangenwe nakho, isikhathi sokuphila sezinto ze-A-grade singafinyelela iminyaka engu-10 ku-105 ° C futhi izinto ze-B-grade zingafinyelela iminyaka engu-10 ku-130 ° C.Kodwa ezimweni zangempela, izinga lokushisa le-ambient kanye nokukhuphuka kwezinga lokushisa ngeke kufinyelele inani lokuklama isikhathi eside, ngakho-ke ubude bempilo buyiminyaka eyi-15 ~ 20.Uma izinga lokushisa lokusebenza lidlula umkhawulo wokushisa osebenzayo wezinto ezibonakalayo isikhathi eside, ukuguga kwe-insulation kuzobe kubi nakakhulu futhi impilo yesevisi izofinyezwa kakhulu.Ngakho-ke, ngesikhathi sokusebenza kwe-motor, izinga lokushisa elizungezile lingenye yezinto eziyinhloko ezithinta impilo yemoto.
Mayelana Nokwenyuka Kwezinga Lokushisa Kwezimoto
Ukwenyuka kwezinga lokushisa umehluko wokushisa phakathi kwemoto nendawo, okubangelwa ukushisa kwemoto.Umnyombo wensimbi wenjini osebenzayo uzodala ukulahleka kwensimbi endaweni yamagnetic eshintshanayo, ukulahleka kwethusi kuzokwenzeka ngemva kokuba ukusongwa kunikwe amandla, kanye nokunye ukulahlekelwa okulahlekile kuzokwenziwa.Lokhu kuzonyusa izinga lokushisa kwemoto.
Ngakolunye uhlangothi, injini iphinde ikhiphe ukushisa.Lapho isizukulwane sokushisa nokushisa kokushisa kufana, isimo sokulinganisa sifinyelelwa, futhi izinga lokushisa alisakhuphuki futhi lizinzile ezingeni.Lapho isizukulwane sokushisa sikhula noma ukuncipha kokushisa kuncipha, ibhalansi izobhujiswa, izinga lokushisa lizoqhubeka likhuphuka, futhi umehluko wokushisa uzonwetshwa, khona-ke ukuchithwa kokushisa kufanele kwandiswe ukuze kufinyelele ibhalansi entsha kwelinye izinga lokushisa eliphakeme.Kodwa-ke, umehluko wokushisa ngalesi sikhathi, okungukuthi, ukunyuka kwezinga lokushisa, kuye kwanda uma kuqhathaniswa nangaphambili, ngakho-ke ukuphakama kwezinga lokushisa kuyinkomba ebalulekile ekwakhiweni nasekusebenzeni kwemoto, okubonisa izinga lokukhiqiza ukushisa kwemoto.
Ngesikhathi sokusebenza kwe-motor, uma izinga lokushisa likhuphuka ngokuzumayo, libonisa ukuthi i-motor inephutha, noma i-air duct ivinjiwe, noma umthwalo unzima kakhulu, noma i-winding ishisiwe. 
Ubudlelwano Phakathi Kwezinga Lokukhuphuka Nezinga Lokushisa Kanye Nezinye Izinto
Enjinini esebenza ngokujwayelekile, ngokwethiyori, izinga lokushisa layo likhuphuka ngaphansi komthwalo olinganiselwe kufanele lizimele kuzinga lokushisa elizungezile, kodwa empeleni lisathintwa izici ezifana nezinga lokushisa elizungezile.
(1) Lapho izinga lokushisa lehla, izinga lokushisa lemoto evamile lizokwehla kancane.Lokhu kungenxa yokuthi ukumelana nama-winging kunciphisa futhi ukulahlekelwa kwethusi kuncipha.Kuwo wonke ukwehla kwezinga lokushisa ngo-1°C, ukumelana kwehla cishe ngo-0.4%.
(2) Ezinjinini ezizipholisa ngokwazo, izinga lokushisa likhuphuka ngo-1.5~3°C kukho konke ukukhuphuka okungu-10°C kwezinga lokushisa elizungezile.Lokhu kungenxa yokuthi ukulahlekelwa kwethusi elisongwayo kuyanda njengoba izinga lokushisa lomoya likhuphuka.Ngakho-ke, ukuguqulwa kwezinga lokushisa kunomthelela omkhulu kuma-motor amakhulu nama-motor avaliwe.
(3) Kuwo wonke u-10% womswakamo womoya ophakeme, ngenxa yokwenziwa ngcono kokusebenza kwe-thermal, izinga lokushisa lingancishiswa ngo-0.07~0.38°C, ngesilinganiso esingaba ngu-0.2°C.
(4) Ukuphakama kungu-1000m, futhi izinga lokushisa likhuphuka ngo-1% yenani lomkhawulo wokwenyuka kwezinga lokushisa kuwo wonke amalitha ayi-100m.
Umkhawulo Wezinga Lokushisa Wengxenye ngayinye Yemoto
(1) Ukwenyuka kwezinga lokushisa kwenkango yensimbi lapho kuthintana nendawo yokujikajika (indlela yokulinganisa izinga lokushisa) akufanele kudlule umkhawulo wokwenyuka kwezinga lokushisa oxhumene nawo (indlela yokumelana), okungukuthi, ikilasi A lingu-60°C, i-E. ikilasi ngu-75°C, kanti ikilasi B ngu-80°C, ikilasi F ngu-105°C kanti ikilasi H ngu-125°C.
(2) Izinga lokushisa eliginqikayo akufanele lidlule ku-95℃, futhi izinga lokushisa lokushelela akufanele lidlule ku-80℃.Ngenxa yokuthi izinga lokushisa liphezulu kakhulu, izinga likawoyela lizoshintsha futhi ifilimu kawoyela izobhujiswa.
(3) Empeleni, izinga lokushisa lebhokisi ngokuvamile lisekelwe eqinisweni lokuthi alishisi esandleni.
(4) Ukulahlekelwa okulahlekile ebusweni be-rotor yekheji yesquirrel kukhulu futhi izinga lokushisa liphezulu, ngokuvamile lilinganiselwe ekungafaki engozini ukuvala okuseduze.Ingalinganiselwa ngokudweba kwangaphambili ngopende wombala ongahlehliseki.
I-Shenzhen Zhongling Technology Co., Ltd. (i-ZLTECH ngamafuphi) yinkampani osekuyisikhathi eside izibophezele ekuzisebenzeleni kwezimboni zezimoto nabashayeli.Imikhiqizo yayo idayiswe emhlabeni wonke, futhi iye yaqashelwa futhi yathenjwa ngamakhasimende ngenxa yokuqina kwayo okuphezulu.Futhi i-ZLTECH ibilokhu isendaweni ehamba phambili embonini, futhi ibilokhu ibambelele emcabangweni wokuqamba okusha okuqhubekayo ukuletha amakhasimende imikhiqizo engcono kakhulu, i-R&D ephelele kanye nohlelo lokuthengisa, ukuhlinzeka amakhasimende ngolwazi olungcono kakhulu lokuthenga.
