Carbon Brush Kwa Motor

Carbon Brush ya Motor

Maburashi nthawi zambiri amatchedwa maburashi a kaboni mu zida zamagetsi. Ndi gawo la injini. Kuphatikiza pa kulumikiza ma elekitironi ndi dera lakunja m'galimoto, imagwiranso ntchito yapano. Ulalo wofooka komanso wofunikira wa mota umapangidwa ndi burashi ndi wowongolera. Palibenso kuvala kwamakina ndi kugwedezeka kwamakina pakati pa burashi ndi wowongolera, komanso kutentha kwakukulu panthawi yogwiritsira ntchito, komwe kungachepetse kwambiri moyo wa chopukutira, komanso kukhudza magwiridwe antchito agalimoto. Chifukwa chake, kusankha koyenera kwa zida za burashi, kukula ndi kuthamanga kwa masika, zomwe zingathandize kwambiri pakuwongolera magwiridwe antchito agalimoto ndikukulitsa moyo wake wautumiki.

Kusankhidwa kwa burashi makamaka kumachokera ku kutentha kwa kukwera kwa burashi, ndipo kutsogolera kwa njirayo kumatsimikiziridwa. Kutentha kwa kutentha kwa burashi kumayenderana ndi kachulukidwe ka bristle ndi kachulukidwe ka njira yolumikizirana, kutayika kwa makina ndi kutenthetsa kwa burashi. Ngati liwiro la mzere wozungulira ndilokwera kwambiri, n'zosavuta kutentha burashi ndi chiwongolero, kuphulika kumawonjezeka, ndipo kuvala kwa burashi ndi kupukuta kumawonjezereka.
Chidziwitso cha kapangidwe kake, kagayidwe ndi magwiridwe antchito a motor carbon brush
Pakagwiritsidwe ntchito, pali makamaka zizindikiro zotsatirazi zakugwiritsa ntchito maburashi abwino: zotsatirazi:

1) Pamene burashi ikuthamanga, imakhala yotentha, phokoso, palibe kuwonongeka, palibe mtundu, osayaka;

2) Khalani ndi magwiridwe antchito abwino, chepetsani kuwala kovomerezeka, ndipo kutaya mphamvu kumakhala kochepa;

3) Moyo wautali wautumiki ndipo musavale chopukutira, musapangitse kupukuta, kusagwirizana, kuyaka, kujambula, ndi zina zotero;

4) Pa opaleshoni, yunifolomu, zolimbitsa thupi, ndi khola woonda oxide filimu akhoza kupangidwa mwamsanga pamwamba pa wotsogolera.


Kapangidwe ka burashi
Upangiri wa burashi ya graphite burashi ndi: mtundu wa radial, wopendekera kumbuyo ndi kutsogolo -kupendekera. Mu mawonekedwe omwe amagwiritsidwa ntchito kawirikawiri, kupanikizika kwa masika kumasiyananso. Pali makasupe a chisa, akasupe ozungulira, ndi masika otambasula. Njira zitatuzi zokankhira masika ndizochita mwachindunji pa burashi ndi kukakamizidwa kwa kasupe; Essence

Gulu ndi ntchito ya burashi

1. Gulu
Maburashi nthawi zambiri amawaika malinga ndi kapangidwe kawo ka mluza ndi njira zochizira

a. Burashi ya carbon graphite

Burashi yachilengedwe ya graphite: maburashi otere amakhala ndi magetsi olumikizana kwambiri, magwiridwe antchito abwino, otsika -otsika ndi otsika kuposa burashi yamagetsi a graphite, magwiridwe antchito abwino, ndipo amagwiritsidwa ntchito pamizere yayikulu yokhala ndi liwiro lalitali.

Burashi yomangira utomoni wa graphite: Burashi yamtunduwu imadziwika ndi kukana kwakukulu, kuchepetsedwa kwamagetsi olumikizana, kutembenuka kwabwino, antioxidant, ndi kukana kwa abrasion ndikoyenera, koma kugwiritsa ntchito mphamvu kumagwiritsidwa ntchito kwambiri poyendetsa ma AC.

b. Ma electrographite brush

Burashi yopangidwa ndi graphite (burashi yofewa): Imadziwika ndi ma coefficients otsika, mafuta abwino, magwiridwe antchito abwino, kukhazikika kwamafuta, komanso magwiridwe antchito a antioxidant; ma motors akulu olumikizana omwe ali ndi liwiro lalitali komanso zonyamula katundu wanthawi yomweyo Ma mota akulu ogudubuza, ndi ma mota a DC ang'onoang'ono ndi apakatikati;

Burashi ya Coke base (burashi yapakati yolimba): Imadziwika ndi kutsika kwakukulu kwamagetsi, imatha kupanga filimu, imatha kusintha mayendedwe ake, imakhala ndi kayendedwe kake ka ma motors ogubuduza omwe ali ndi mphamvu inayake, etc. Ndipo ambiri DC Motors ndi voteji apamwamba kuposa 220V;

Burashi ya inki ya carbon (burashi yolimba): Burashi yamtunduwu ndi ya burashi yolimba kwambiri ya electro-chemical graphite brush. Amadziwika ndi kukana kwakukulu kolumikizana ndi burashi komanso magwiridwe antchito abwino. Amagwiritsidwa ntchito kwa ma motors a DC movutikira kusintha komwe akupita.

c. Kalasi ya burashi ya Metal graphite
Amakhala ndi zitsulo ndi graphite. Makhalidwe a zitsulo ndi graphite amasinthidwa ndi makhalidwe abwino zitsulo madutsidwe ndi mafuta kondomu wabwino. Amadziwika ndi magetsi ang'onoang'ono okhudzana, kukana kokwanira komanso kutaya magetsi. Burashi iyi imagwiritsidwa ntchito makamaka pama motors otsika -voltage yayikulu komanso ma motors otsika kwambiri a AC.

Natural graphite burashi ndi electroextburra burashi resistor coefficients ndi madontho burashi kuthamanga ndi zazikulu, zambiri abrasion kugonjetsedwa, ndi liwiro la mzere amaloledwa kugwiritsidwa ntchito (angafikire 50 ~ 70m/s). Metal graphite burashi resistor coefficient ndi brush voteji amachepetsa pang'ono, ndi abrasion kukana ndi osauka. Liwiro la mzere wololedwa kugwiritsa ntchito ndilotsika. Pafupifupi 15 ~ 35m / s.

2. Magwiridwe
Zinthu zazikuluzikulu zaukadaulo wa burashi zimaphatikizirapo resistors, kuuma, kuuma kwa maburashi, ma coefficients okangana, kuvala kwa 50H, ndi zina zambiri. Kukaniza kokwanira ndi kuchuluka kwa thupi kuyeza magwiridwe antchito. Pa 230V, choyezera chamagetsi cha brush resistor chingasankhidwe chokulirapo, ndipo 120V brush resistor coefficient iyenera kukhala yaying'ono. Magetsi amagetsi a 120V okhala ndi mphamvu yomweyo ndi yayikulu kuposa 230V. Kutentha, kutentha kwamphamvu kungakhale koipitsitsa kwambiri.

Kutsika kwamagetsi kwa maburashi awiri ndikusiyana komwe kungathe pakati pa zomwe zikuyenda muburashi kudzera pakusintha kupita ku burashi. Pamene burashi ikukhudzana wina ndi mzake, ndi kukana kwa kukhudzana pamwamba pamene kukhudzana pamwamba kumachitika pansi pa zochita za mphamvu zakunja, amatchedwa kukangana. Chiŵerengero cha mikangano ndi kuthamanga kwa masika ndi coefficient coefficient ya burashi ndi wotsogolera. Kuvala kwa 50H: Pansi pa zoyeserera zomwe zafotokozedwa, burashi imatsimikiziridwa ndi kachulukidwe kakali pano komanso kukakamizidwa kwa unit. Pamene liwiro la mzere ndi 15m / s, kuchuluka kwa kuvala kwa burashi kumapukutidwa ndi 50h.
