Mukugadzira batch, isu tinowanzo kusangana nemamiriro ezvinhu aya: dzimwe nguva kuremara kwakasiyana kunoonekwa nekuda kwechikonzero chinoratidzika sechinhu chimwe chete, uye dzimwe nguva kukanganisa kwakafanana kunoitika nekuda kwezvikonzero zvakasiyana. Izvi zvinoratidza kuti rotor defects inowanzova mugumisiro wekubatanidzwa kwezvinhu zvakawanda zvisina kunaka. Chokwadi, panofanira kuva nechikonzero chikuru. Kana mamiriro ezvinhu achichinja, kunyange kana chikanganiso chimwe chete chikaitika, chikonzero chikuru chechikanganiso chichachinja.
Semuyenzaniso, rotor pores anowanzo kukonzerwa nekusaita mold exhaust kana mold exhaust slot blockage. Zvisinei, dzimwe nguva, kunyange kana slot yekutsvaira isina kuvharwa, gasi rinosara harigoni kubudiswa munguva nekuda kwekumhanya kukuru kwekudurura, izvo zvichaitawo kuti pores mu rotor. Panguva ino, chikonzero chikuru che rotor pores haisisiri dambudziko rekupedza mold, asi dambudziko rekudurura rinokurumidza. Naizvozvo, kana uchiongorora matambudziko emhando yeakakandirwa aluminium rotors, zvinodikanwa kuita ongororo yakazara zvichienderana nenzvimbo uye maitiro eiyo rotor defects uye mamiriro akasiyana-siyana kuitira kuti uwane zvakanyanya zvikonzero zvinokonzeresa zvemhando yezvinetso uye kutora matanho anoenderana kudzivirira zvinobudirira kuitika kweakakanda aluminium rotor defects.
Yakabatanidzwa nekuremara kwemarotor mazariro akaonda, mbariro dzakaputsika, shrinkage maburi, kuputika, nezvimwewo zvataurwa pamusoro apa, Ms. San achatarisa pane inotonhora yekuvhara uye rotor conformity nyaya dze cast aluminium rotors neBaowei nhasi. Kukundikana kwealuminium yakanyungudutswa kuzadza zvachose mold cavity inonzi "incomplete kudira". Nzvimbo iyo rotor isina kudururwa kana mipendero isina kujeka inonyanya kuve ma blades fan uye chiyero mbiru. Cold shut (Cold shut) zvinoreva majoini kana makomba umo aruminiyamu yakanyunguduka isina kunyatsobatanidzwa. Mupendero wemharadzano wakatsetseka uye unonyanya kuoneka pamashizha e fan.
Zvinokonzera kutonhora kuvhara kuremara
● Kupisa kwealuminium yakanyungudutswa yakaderera zvikuru panguva yekudira; kumhanya kwekudira kunononoka kana kuti pane kuyerera kunovhiringidza chiitiko. ● Tembiricha ye mold uye core yakaderera. ● Aruminiyamu kuvuza kana kusakwana aruminiyamu yakanyungudutswa. ● Kusakwana kwekutenderera kumhanya. ● Chikamu chemuchinjikwa chegedhi remukati idiki zvakanyanya kana mold haina kubuda zvakanaka. ● Yakapatsanurwa ne oxide scale kana zvimwe zvinosanganisirwa. Cold shut defect control zviyero ● Tembiricha yealuminium yakanyungudutswa inofanira kusangana nemutengo wakatarwa, uye kumhanya kwekudira kunofanirwa kudzorwa nemazvo. Inofanira kudirwa panguva imwe chete. ● Kuwedzera zvakakodzera kupisa kwepakati uye kutonhora kwemuumbi, kunyanya kupisa kwepamusoro (kune zvigadzirwa zvakaderera, wedzera mold yakaderera ● Bvisa aluminium kuvuza. Paunenge uchidira aluminium, shandisa 10 ~ 20% kupfuura rotor chaiyo. ● Dzora kukurumidza. Kana kukurumidza kwakanyanyisa pakutanga kwekupfachukira;
zvinozoita kuti pasi zvisimbe. (5) Chengetedza tsvina isina kudzivirirwa uye zuva rekudira rinogona kuwedzerwa zvakakodzera. ● Chengeta chakuvhe nepakati zvakachena uye zvisina tsvina. Ngwarira kukurudzirwa uye kucheneswa kwemvura inowirirana. Rotor resistance inodarika kushivirira (1) Kuongororwa kwezvikonzero zvekudzivirira kwerotor kunopfuura kushivirira ● Nheyo yakanyanyisa yakareba, kana kuti slot slope yakakura kudarika kukosha kunobvumirwa, iyo inowedzera cage bar resistance. ● Iyo rotor haina kurongeka uye serrated, iyo inoderedza inoshanda nzvimbo yealuminium bar. ● Aluminium mvura Kuchenesa kana kuchenesa slag hakuna kunaka, uye ine nhamba yakawanda yemapini uye tsvina. ● Unhu hwe rotor aluminium casting yakashata, ine zvikanganiso zvakadai semapores, shrinkage cavities, shrinkage, slag inclusions, kuputika kana kuvhara kunotonhora. ● Chikamu chisina kunaka chealuminium ingot chinoshandiswa kana kuti hutano hwakashata, uye conductivity yakaderera. (2) Rotor kuramba idiki, iyo inonyanya kuitika mualuminium alloy rotors. Zvingave kuti high-purity aluminium ingots inoshandiswa zvisiri izvo, kana slot slope ishoma pane kukosha, iyo inoderedza cage bar resistance. Kudzora matanho ekudzivisa rotor kunze-kwe-kushivirira matambudziko ● Usati watsikirira nekudurura musimboti, teerera kutarisa kureba kwepakati uye slot slope, iyo inofanira kusangana nezvinodiwa zvekudhirowa. ● Ita basa rakanaka rekuchenesa uye kubvisa slag yealuminium liquid. ●Bvisa kukanganiswa kwe rotor senge pores uye shrinkage cavities. ●Shandisa aluminium ingots yegiredhi rakatarwa.
