Indlela yokukhetha imathiriyeli yokugquma ibhodi yemica kwimveliso yabahambi

Ibhodi ye-commutator mica, ekwabizwa ngokuba yibhodi ye-commutator mica, yenye yezona zinto zibalulekileyo zokukhusela kwi-DC motors. Kukho izinto ezimbini eziphambili zokwenza ibhodi ye-commutator mica: enye yindawo encinci ye-mica sheet, kwaye enye yi-powder mica paper. Ukuze wenze imveliso ifikelele kubukhulu obufunekayo, i-mica plate eyenziwe ngamaphepha e-mica kufuneka icolile okanye ipholishwe. Xa ucinezela, amacala amabini ahlanganiswe nephepha le-liner ehlukeneyo kunye ne-canvas, ukwenzela ukuba ubukhulu bufanane kwaye ukuqina kwangaphakathi kuphunyezwe emva koxinzelelo. Xa iphepha le-powder mica lisetyenziselwa ukwenza ibhodi ye-powder mica, ukuba imeko yokucinezela ilungile, inkqubo yokugaya okanye yokugaya ingashiywa.

Ukongeza, ngokwamanqanaba ahlukeneyo okugquma kwemoto, kunye neemfuno ze-anti-arc kunye nokumelana nokufuma, i-shellac, ipeyinti yepolyester, ipeyinti ye-melamine polyacid, isisombululo samanzi se-ammonium phosphate, iglue ye-cyclic resin okanye ipeyinti eguquliweyo ye-silicone isetyenziswa njengezinto zokuncamathelisa. ukuvelisa Iindidi ezahlukeneyo zeebhodi zemica.

Ukusetyenziswa kwe-shellac kunokuvelisa iiplate ze-mica ze-commutator ezinokufikelela kwiqondo lokushisa kwe-100 ° C nangaphezulu, kubandakanywa neeplati zefu ze-commutator ze-motor-speed speed. Kodwa into engalunganga kukuba ukusebenza kwemveliso kuphantsi.

Kungcono kune-shellac ukusebenzisa i-polyacid resin condensed from ortho-jasmonic anhydride kunye ne-glycerin. Kulula ukukrazula kunye nokunamathela kumaphepha e-mica, kwaye inokwenza ngokuzenzekelayo inkqubo yokunamathisela amaphepha e-mica, ukwenzela ukuba inani elikhulu labanini-mhlaba linokuvelisa iibhodi ze-commutator mica. . Nangona kunjalo, ukungahambi kakuhle kukuba kukho i-resin e-unpolymerized kwibhodi ye-mica, kwaye i-depolymerization ye-resin kwibhodi ye-mica iqiniswa phantsi kwefuthe lobushushu obuphezulu kunye noxinzelelo oluphezulu. kumphezulu wesihambisi semoto.

Xa usebenzisa ipleyiti ye-polyacid resin commutator mica njengemoto yobushushu obuphezulu ukugquma i-crane yokutsala okanye imoto enkulu, kufuneka ifudunyezwe phambi kokusetyenziswa. Emva kokwenza njalo, xa ucinezela i-commutator, ukuphuma kwe-resin kuya kuncitshiswa, okuqinisekisa ukuthembeka kwe-commutator ekusebenzeni.

Ukusetyenziswa kwe-Anfu powder njenge-adhesive kunokwenza ukusebenza kwebhodi ye-commutator mica ingatshintshi phantsi kweemeko zomswakama ophezulu kunye nokushisa (200 ℃ okanye ngaphezulu). Izinga lokucutheka kwayo lincinci kunezinye iibhodi zemica, kwaye ukumelana nobushushu bayo bungaphezulu kwe-600 ℃. Ngoko ke, umgangatho wayo uphezulu kakhulu kuneebhodi zemica ezikhankanywe ngasentla, kwaye uluhlu lwesicelo lubanzi.

Ibhodi ye-mica eyenziwe nge-epoxy okanye i-melamine kunye ne-polyacid resin inokumelana ne-arc efanelekileyo kwaye isetyenziswe kwiinjini ze-DC ezinesantya esiphezulu.

Ibhodi ye-mica eyenziwe nge-resin eguquliweyo yezinto eziphilayo inokumelana nokushisa okuphezulu kwaye isetyenziswe kwiimoto ezikhethekileyo zokuhamba.

I-NIDE ibonelela ngeebhodi zemica ezahlukeneyo kunye nabahambisi, ezisetyenziswa kakhulu kwindawo yezixhobo zamandla, iimotor ezingenasibhrashi, iimotor zemoto zamandla amatsha, izixhobo zasekhaya, iitafile zokuphakamisa, iibhedi zezixhobo zonyango kunye nezinye iindawo.
