Wamng'onoangle grindersndizida zamagetsizomwe timagwiritsa ntchito nthawi zambiri pamoyo wathu watsiku ndi tsiku, koma kukonza zopukutira m'makona nthawi zambiri zimanyalanyazidwa, choncho ndikufuna kukumbutsani aliyense kuti akufunikanso kusungidwa pakugwiritsa ntchito.
1. Yang'anani nthawi zonse ngati chingwe chamagetsi chili cholimba, ngati pulagi ndi yotayirira, komanso ngati kusinthaku kuli kosavuta komanso kodalirika.
2. Yang'anani ngati burashiyo yavala yayifupi kwambiri, ndipo sinthani burashiyo pakapita nthawi kuti musapse kwambiri kapena kuwotcha zida chifukwa chosalumikizana bwino ndi burashi.
3. Samalani kuti muwonetsetse kuti cholowetsa mpweya ndi mpweya wa chidacho sichimatsekedwa, ndikuchotsani mafuta ndi fumbi ku gawo lililonse la chida.
4. Mafuta ayenera kuwonjezeredwa panthawi yake.
5. Ngati chidacho chikulephera, tumizani kwa wopanga kapena ofesi yokonza yokonzedweratu kuti iwonongeke.Ngati chida chawonongeka chifukwa cha kugwiritsidwa ntchito kwachilendo kapena zolakwika zaumunthu pakusokoneza ndi kukonza, wopanga nthawi zambiri sangakonze kapena kusinthanitsa kwaulere.
6. Yang'anani chizindikiro chachopukusira ngodya.Ma angle grinders omwe sangathe kugwiritsidwa ntchito ndi awa: osadziwika, omwe sangatchulidwe momveka bwino, ndi omwe sangathe kutsimikiziridwa, mosasamala kanthu kuti ali ndi zofooka kapena ayi.
7. Yang'anani zofooka za grinding angle. Pali njira ziwiri zoyendera: kuyang'anitsitsa maso, mwachindunji gwiritsani ntchito maso anu kuti muwone pamwamba pa chopukusira ngodya chifukwa cha ming'alu ndi mavuto ena;kuyang'ana kwa percussion, yomwe ndi gawo lalikulu la kuyang'ana kwa chopukusira ngodya, njirayo ndikumenya chopukusira ngodya ndi mallet amatabwa.Ngati palibe vuto ndi chopukusira ngodya, chiyenera kukhala phokoso lomveka, ngati pali zina phokoso, limasonyeza kuti pali vuto.
8. Yang'anani mphamvu yozungulira ya chopukusira ngodya.Gwiritsani ntchito zopukutira zamtundu womwewo wa gulu lomwelo la zitsanzo kuti muyang'ane mphamvu yozungulira, ndi zopukutira zomwe sizinayesedwe zisayikidwe ndikugwiritsidwa ntchito.
Maburashi amagetsi amatha kugwiritsidwa ntchito mu ma DC motors kapena AC commutator motors, monga zida zamagetsi zomwe zimagwiritsidwa ntchito nthawi zonse, monga dzanja.kubowolandiangle grinders.Imagwiritsidwa ntchito kugwirizana ndi commutator kuti azindikire kusintha kwa injini.Ndi gulu lolumikizana lotsetsereka la mota (kupatula mota ya gologolo) kuti igwire ntchito yapano. zinatsimikizira kuti kudalirika kwa ntchito yamagalimoto kumadalira kwambiri momwe burashi ikuyendera.
Kukonza kutayikira
Zolakwika zomwe zimayambitsa kutayikira kwa ma angle grinders ndi: stator leakage, rotor leakage, burashi mpando kutayikira (angle chopukusira ndi zitsulo chipolopolo) ndi mkati waya kuwonongeka.
1) Chotsani burashi kuti muwone ngati stator, chosungira burashi ndi mawaya amkati akutha.
2) Lumikizani chingwe cholumikizira pakati pa stator ndi chogwirizira burashi kuti muwone ngati chogwirizira chikuwotcha magetsi.
3) Yezerani pawokha ngati rotor ikuwotcha magetsi.
Rotor ndi burashi chofukizira akhoza m'malo kutayikira, ndipo stator akhoza rewound kapena m'malo.
Choyamba, phatikizani ndikuyang'ana ngati khungu la mawaya lawonongeka.Gwiritsani ntchito ma multimeter kuti muwone chassis, kenako chotsani chozungulira ndikuchiyeza.Itha kuyeza ngati rotor ikutha kapena stator ikutha.Rotor ikhoza kusinthidwa.Stator imatuluka kuti awone ngati ufa wa carbon brush ndi zinyalala zina zimachuluka kwambiri ndipo kutayikirako kumayamba.Yeretsani ndikuyesa.The kutayikira kumatanthauza kuti stator mapiringidzo si insulated bwino, ndi kuona ngati mapiringidzo chikugwirizana ndi chipolopolo kapena yonyowa.Ngati sichoncho, ikhoza kubwezeretsedwanso.
Kulakwitsa ndi njira yothetsera vuto la chopukusira ngodya.Chopukusira ngodya chimagwiritsa ntchito injini yosangalatsa yotsatizana.Makhalidwe a injini iyi ndi yakuti ili ndi maburashi awiri a carbon ndi commutator pa rotor.
Magawo omwe amawotchedwa kwambiri amtundu woterewu ndi ma commutator ndi malekezero a rotor.
Ngati commutator yatenthedwa, kupanikizika kwa burashi ya kaboni nthawi zambiri sikukwanira.Motor ikugwira ntchito, ngati magetsi akupitirizabe kukhala aakulu, burashi ya carbon idzatha mwamsanga.Pambuyo pa nthawi yayitali, burashi ya kaboni idzakhala yayifupi, kupanikizika kudzakhala kochepa, ndipo kukana kukhudzana kudzakhala kwakukulu kwambiri.Panthawiyi, kutentha pamwamba pa commutator kudzakhala koopsa kwambiri.
Ngati mbali yokhotakhota yatenthedwa, zikutanthauza kuti chopukusira ngodya chimayika kupanikizika kwambiri pa chopukusira ntchito pamene chikugwira ntchito, mphamvu yothamanga ndi yaikulu kwambiri, ndipo galimotoyo imakhala yodzaza kwambiri kwa nthawi yayitali. wamphamvu kwambiri.
