Ngokuthuthuka komphakathi, izakhiwo eziphakeme ziye zaba umkhakha wentuthuko yasemadolobheni emhlabeni wonke, futhi amakheshi asephenduke izindlela zokuthutha ezidingekayo zokuphila kwansuku zonke.Kumakheshi, umshini wokudonsa uyinhliziyo yekheshi, futhi ukusebenza kwawo kuhlobene nokuphepha kwempilo yabantu.Ukusebenza kwe-Nd-Fe-B njengengxenye eyinhloko kuthinta kakhulu ukuzinza nokuphepha kokusebenza kwekheshi.
I-China ingumkhiqizi omkhulu wamakheshi, umthengi kanye nomthumeli ngaphandle.I-China Elevator Association ibala ukuthi ukusetshenziswa kwamandla kwamakheshi kufinyelela ku-5% wokusetshenziswa kwamandla kwesakhiwo sonke, okusho ukuthi amakheshi angenye yemishini emikhulu edla amandla ezakhiweni eziphakeme kakhulu.
Umshini wokudonsa ozibuthe waphakade uthathe indawo enkulu emakethe.Njengamanje, inketho ephelele ye-elevator drive motor.Ngakho-ke, isidingo sikazibuthe womshini wokudonsa ikheshi sibe sikhulu kakhulu.
I-elevator yomshini wokudonsa ngokuyinhloko yakhiwe uhlelo lokudonsa, uhlelo lokuqondisa, uhlelo lwesango, imoto, uhlelo lokulinganisa isisindo, uhlelo lokushayela ugesi, uhlelo lokulawula amandla kanye nesistimu yokuvikela ukuphepha.Umshini wokudonsa ukhipha futhi udlulise amandla okushayela ikheshi ukuze lisebenze ngokujwayelekile.
Umshini wokudonsa wakhiwe ngenjini, ibhuleki, i-coupling, u-gearbox wokunciphisa, isondo elidonsayo, uhlaka kanye nesondo eliqondisayo.Umshini wokudonsa ungahlukaniswa ube umshini wokudonsa we-DC kanye nomshini wokudonsa we-AC ngokuya ngohlobo lwemoto, kuyilapho umshini wokudonsa we-AC ungahlukaniswa ngomshini wokudonsa wegiya we-AC, umshini wokudonsa ongenagiya we-AC kanye nomshini wokudonsa unomphela ozibuthe.Umshini wokudonsa ongenamagiya ozibuthe waphakade usetshenziswa kakhulu embonini yekheshi ngenxa yevolumu yawo encane, ukusebenza okuzinzile ngesivinini esiphansi, akukho kunakekelwa, ukusetshenziswa kwamandla okuphansi nomsindo ophansi.
Ukusebenza okuphezulu okungavamile komhlaba we-neodymium uzibuthe kungenye yezingxenye eziyinhloko zomshini wokudonsa ikheshi.Njengomthombo ovusa amadlingozi womshini wokudonsa, ukulahleka kukakazibuthe okungenakulungiseka kuzoletha izingozi ezingaba khona zokuphepha kulo lonke uhlelo lwekheshi.
Ozibuthe bemishini yokudonsa ikheshi ngokuvamile basebenzisa i-n35sh, n38sh, n40sh kanye ne-n33uh esebenza kahle kakhulu ye-neodymium iron boron.Esikhathini esithile somlando, ukukhula okuqhumayo komshini wokudonsa ikheshi kuye kwakhuthaza ukuthuthukiswa kozibuthe be-neodymium iron boron high coercivity sintered neodymium iron boron magnets ngokwezinga elithile.
I-Honsen Magnetics ilawula ngokuqinile ikhwalithi esekelwe kumagugu enkampani "ikhwalithi kuqala nokuphepha kuqala"! Umgomo wethu uwukwenza umkhiqizo ngamunye ulandeleke futhi sibeke isisekelo esiqinile sokunethezeka nokuphepha kwabantu kwezohambo.
