Ibrashi yeCarbon yeMoto

Ibrashi yeCarbon yeMoto

Iibrashi zidla ngokubizwa ngokuba ziibrashi zekhabhoni kwizixhobo zombane. Lilungu lenjini. Ukongeza kokudibanisa i-electron kunye nesekethe yangaphandle kwi-motor, iphinda idlale indima yangoku. Ikhonkco elibuthathaka kwaye elibalulekileyo lemoto lenziwa yi-brush kunye nomkhombandlela. Akukho kuphela ukunxiba komatshini kunye nokungcangcazela komatshini phakathi kwebrashi kunye nesikhokelo, kodwa kunye nentlantsi enzima ngexesha lokusetyenziswa, okuya kunciphisa kakhulu ubomi be-wiper, kodwa kuchaphazele nokusebenza okuqhelekileyo kwemoto. Ngoko ke, ukhetho olufanelekileyo lwezixhobo zebrashi, ubungakanani kunye noxinzelelo lwentwasahlobo, oluya kudlala indima ebaluleke kakhulu ekuphuculeni indlela yokusebenza yemoto kunye nokwandisa ubomi bayo benkonzo.

Ukukhethwa kwebrashi ikakhulu kusekelwe ekunyukeni kweqondo lobushushu kwibrashi, kwaye isalathiso sendlela yesalathiso sichongiwe. Ukunyuka kweqondo lokushisa kwebrashi kuhambelana nokuxinana kwe-bristle kunye nokuxinana koqhagamshelwano lolwalathiso, ukulahleka komatshini kunye ne-thermal conductivity ye-brush. Ukuba isantya somgca wesetyhula siphezulu kakhulu, kulula ukutshisa i-brush kunye ne-directer, i-spark iyanda, kwaye i-brashi yokugqoka kunye ne-wiper iyancipha.
Intshayelelo kulwakhiwo, ulwahlulo kunye nokusebenza kwebrashi yekhabhoni yemoto
Ngokombono wokusetyenziswa, kukho ubukhulu becala ezi mpawu zilandelayo zokusetyenziswa kweebhrashi ezilungileyo: ezi meko zilandelayo:

1) Xa i-brush isebenza, ishushu, isandi, akukho monakalo, akukho mbala, ayitshisi;

2) Yiba nokusebenza kakuhle kolwalathiso, uthintele i-spark kuluhlu oluvumelekileyo, kwaye ukulahlekelwa kwamandla kuncinci;

3) Ubomi benkonzo ende kwaye ungagqoki i-wiper, musa ukwenza i-wiper scratch, ukungalingani, ukutshisa, ukudweba, njl.;

I-4) Ngethuba lokusebenza, ifilimu ye-oxide ye-uniform, imodareyitha, kwaye izinzile inokwakheka ngokukhawuleza kumphezulu wesikhokelo.


Ubume bebrashi
Ulwalathiso lofakelo lwebrashi yebrashi yegraphite yile: uhlobo lweradial, i-tilt ngasemva kunye ne-front-tilt. Kwisakhiwo se-radial esisetyenziswa ngokuqhelekileyo, uxinzelelo lwentwasahlobo lukwahluke. Ubukhulu becala kukho imithombo ye-nest line, i-spiral springs, kunye ne-stretch spring. Ezi ndlela zintathu zokucinezela intwasahlobo kukwenza ngokuthe ngqo kwibrashi ngoxinzelelo lwentwasahlobo; Undoqo

Ukuhlelwa kunye nokusebenza kwebrashi

1. Ukuhlelwa
Iibhrashi zihlelwa ngokubanzi ngokwezinto zazo zeembryo kunye neendlela zonyango

a. Ibrashi yekhabhoni yegraphite

Ibhrashi yendalo yegraphite: ezo brashi zinombane ophezulu wokuqhagamshelana, ukusebenza kakuhle kokulungiswa, ukusebenza okuphantsi kokuhamba kusezantsi kunebrashi yegraphite yombane, ukusebenza kakuhle kokuthambisa, kwaye isetyenziselwa imigca ephezulu enezantya zemigca ephezulu.

Ibrashi ye-resin bonding graphite: Olu hlobo lwebrashi luphawulwa kukuxhathisa okukhulu, ukuncitshiswa kombane wokunxibelelana, ukusebenza kakuhle koguqulo, i-antioxidant, kunye nokuxhathisa kwe-abrasion kufanelekile, kodwa ukusetyenziswa kwamandla kusetyenziswa kakhulu kwiimotor zokuhambisa i-AC.

b. Ibrashi yegraphite yombane

Ibrashi esekelwe kwigraphite (ibrashi ethambileyo): Ibonakaliswe ngama-coefficients aphantsi okukhuhlana, ukusebenza kakuhle kwe-lubrication, ukusebenza kakuhle kokumisela, ukuzinza kwe-thermal, kunye nokusebenza kwe-antioxidant; iinjini ezinkulu ezijikelezayo ezinezantya zemigca ephezulu kunye nemithwalo yempembelelo ekhawulezileyo Iimotor ezinkulu eziqengqelekayo, kunye neenjini zeDC ezincinci neziphakathi;

Ibhrashi yesiseko se-coke (ibrashi enzima ephakathi): Ibonakaliswa kukuhla kwamandla ombane omkhulu, inamandla okwenza ifilim, inekhono elihle lokutshintsha isalathiso, inompompoza othile wokuqengqeleka kweenjini ezinomthwalo othile wempembelelo, njl. kunye neenjini ze-DC ngokubanzi ezinombane ongaphezulu kwe-220V;

Ibrashi ye-inki yekhabhoni (ibrashi eqinileyo): Olu hlobo lwebhrashi yeye-high-resistance brush ye-electro-chemical graphite brush. Ibonakaliswe ngokuxhathisa okukhulu koqhagamshelwano lwebrashi kunye nokusebenza kakuhle kolwalathiso. Isetyenziselwa iinjini zeDC ngobunzima ekutshintsheni indlela.

c. Iklasi yebrashi yesinyithi yegraphite
Iqukethe isinyithi kunye negraphite. Iimpawu zetsimbi kunye negraphite zihlengahlengiswa ngeempawu zokuqhuba kakuhle kwentsimbi kunye nokuthambisa okulungileyo. Ibonakaliswa ngumbane omncinci woqhagamshelwano, i-coefficient yokumelana kunye nokulahlekelwa kombane. Le ibhrashi ikakhulu isetyenziselwa low -voltage iinjini ezinkulu zangoku kunye low -voltage AC ukujija iimotor.

Ibrashi yendalo yegraphite kunye ne-electroextburra brush resistor coefficients kunye ne-brush pressure drops zinkulu, zixhathisa i-abrasion, kunye nezantya zomgca zivumelekile ukuba zisetyenziswe (zinokufikelela kwi-50 ~ 70m / s). I-Metal graphite brush resistor coefficient kunye ne-brush voltage iyancipha kancinane, kwaye ukuxhathisa kwe-abrasion kubi. Isantya somgca esivunyelwe ukusetyenziswa siphantsi. Malunga ne-15 ~ 35m/s.

2. Ukusebenza
Izinto eziphambili zeteknoloji yebrashi ziquka i-resistors, ubunzima, ubunzima kwi-pair of brushes, i-friction coefficients, i-50H yokunxiba, njl njl. I-coefficient yokuchasana yinani lomzimba lokulinganisa ukusebenza kwe-conductive. Kwi-230V, i-coefficient ye-brush resistor coefficient ingakhethwa inkulu, kwaye i-coefficient ye-120V ye-brush resistor kufuneka ibe yincinci. Imisinga yemoto ye-120V yombane enamandla afanayo mkhulu kune-230V. Ukufudumeza, ubushushu bokubamba bunokuba bubi kakhulu.

Ukuhla kwamandla oqhagamshelwano kwiperi yeebrashi ngumahluko kumahluko onokuthi ubekho phakathi kwangoku oqukuqelayo kwibrashi ngokutshintshela kwibrashi. Xa i-brush idibanisa kunye, kunye nokuchasana kwendawo yokudibanisa xa indawo yokudibanisa iyenzeka phantsi kwesenzo samandla angaphandle, kuthiwa yi-friction. Umlinganiselo wengxabano kunye noxinzelelo lwentwasahlobo yi-coefficient ye-friction ye-brush kunye ne-directioner. Ixabiso le-50H yokugqoka: Ngaphantsi kweemeko zokulinga ezichaziweyo, i-brush inqunywe ngokuxinwa kwangoku kunye noxinzelelo lweyunithi emiselweyo. Xa isantya somgca wenguqu si-15m / s, isixa sokugqoka kwebrashi sigaywa ngu-50h.
