Carbon Txhuam Rau Tsav

Carbon Txhuam rau Tsav

Txhuam yog feem ntau hu ua carbon txhuam hauv cov cuab yeej hluav taws xob. Nws yog ib feem ntawm lub cev muaj zog. Ntxiv nrog rau kev sib txuas ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob sab nraud hauv lub cev muaj zog, nws kuj tseem ua lub luag haujlwm ntawm qhov tam sim no. Ib qho kev sib txuas tsis muaj zog thiab tseem ceeb ntawm lub cev muaj zog yog tsim los ntawm kev txhuam nrog tus taw qhia. Tsis yog tsuas yog siv cov khoom siv kho tshuab thiab kev vibration ntawm cov txhuam hniav thiab cov kev taw qhia, tab sis kuj muaj lub txim loj heev thaum lub sijhawm siv, uas yuav txo tau lub neej ntawm lub wiper, tab sis kuj cuam tshuam rau kev ua haujlwm ntawm lub cev muaj zog. Yog li ntawd, qhov tsim nyog xaiv cov khoom siv txhuam, qhov loj me thiab lub caij nplooj ntoos hlav siab, uas yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov kev taw qhia ntawm lub cev muaj zog thiab txuas ntxiv nws lub neej kev pab cuam.

Kev xaiv ntawm txhuam yog tsuas yog nyob ntawm qhov kub ntawm qhov nce ntawm tus txhuam, thiab qhov kev taw qhia ntawm qhov kev taw qhia yog txiav txim siab. Qhov kub nce ntawm cov txhuam hniav muaj feem xyuam rau qhov ntom ntawm cov txhuam hniav nrog qhov ceev ntawm kev taw qhia kev sib cuag, cov neeg kho tshuab poob thiab thermal conductivity ntawm txhuam. Yog hais tias qhov ceev ntawm txoj kab ncig yog siab dhau lawm, nws yooj yim rau cua sov cov txhuam thiab cov kev taw qhia, lub txim hluav taws xob nce ntxiv, thiab hnav cov txhuam hniav thiab cov wiper yog exacerbated.
Taw qhia rau cov qauv, kev faib tawm thiab kev ua haujlwm ntawm lub cev muaj zog carbon txhuam
Los ntawm kev xav ntawm kev siv, feem ntau yog cov cim hauv qab no ntawm kev siv cov txhuam hniav zoo: cov xwm txheej hauv qab no:

1) Thaum txhuam tau khiav, nws kub, suab nrov, tsis muaj kev puas tsuaj, tsis muaj xim, tsis kub;

2) Muaj kev coj ua tau zoo, cuam tshuam lub txim hauv qhov kev tso cai, thiab lub zog poob yog me me;

3) Lub neej ua haujlwm ntev thiab tsis hnav lub wiper, tsis txhob ua kom lub wiper khawb, tsis sib xws, hlawv, kos duab, thiab lwm yam.;

4) Thaum lub sijhawm ua haujlwm, ib qho tsis sib xws, nruab nrab, thiab ruaj khov nyias oxide zaj duab xis tuaj yeem tsim sai sai rau ntawm tus taw qhia.


Cov qauv ntawm txhuam
Cov kev taw qhia kev teeb tsa ntawm cov txhuam ntawm graphite txhuam yog: hom radial, nraub qaum thiab pem hauv ntej-tilt. Hauv cov qauv siv radial feem ntau, lub siab ntawm lub caij nplooj ntoos hlav kuj txawv. Feem ntau muaj zes kab springs, kauv springs, thiab stretch springs. Peb txoj kev nias lub caij nplooj ntoos hlav no yog ua ncaj qha rau ntawm txhuam los ntawm lub siab ntawm lub caij nplooj ntoos hlav; Qhov tseem ceeb

Kev faib tawm thiab kev ua haujlwm ntawm txhuam

1. Kev faib tawm
Txhuam yog feem ntau cais raws li lawv cov khoom siv embryo muaj pes tsawg leeg thiab cov txheej txheem kev kho mob

a. Carbon graphite txhuam

Ntuj graphite txhuam: cov txhuam zoo li no muaj qhov sib tiv tauj siab, kev ua haujlwm zoo, kev ua haujlwm qis qis qis dua li cov hluav taws xob graphite txhuam, zoo lubrication kev ua tau zoo, thiab siv rau cov kab siab nrog cov kab nrawm.

Resin bonding graphite txhuam: Hom txhuam no yog tus cwj pwm los ntawm kev ua haujlwm loj, txo kev sib cuag voltage, kev hloov pauv zoo, antioxidant, thiab kev txhuam tsis zoo yog qhov zoo tagnrho, tab sis lub zog noj feem ntau yog siv rau AC streaming motors.

b. Electrifying graphite txhuam

Graphite-raws li txhuam (mos txhuam): Nws yog tus cwj pwm los ntawm kev sib txhuam coefficients qis, kev ua haujlwm zoo lubrication, kev ua haujlwm zoo, thermal stability, thiab kev ua haujlwm antioxidant; loj synchronous motors nrog cov kab ntau dua thiab cov kev cuam tshuam tam sim loj dov motors, thiab me me thiab nruab nrab DC motors;

Coke base brush (medium hard brush): It is characterized by a large contact voltage drop, has a good ability to form a film, has a good ability to replace the direction, has a certain flow of rolling motors with a certain impact load, etc. And general DC motors with voltage higher than 220V;

Carbon number case txhuam (nyuaj txhuam): Hom txhuam no belongs rau high-resistance txhuam rau electro-chemical graphite txhuam. Nws yog tus cwj pwm los ntawm kev txhuam loj tiv thaiv thiab kev ua haujlwm zoo. Nws yog siv rau DC motors nrog nyuaj rau kev hloov cov kev taw qhia.

c. Hlau graphite txhuam chav kawm
Nws muaj cov hlau thiab graphite. Cov yam ntxwv ntawm cov hlau thiab graphite yog kho los ntawm cov yam ntxwv ntawm cov hlau zoo conductivity thiab lubricating zoo lubrication. Nws yog tus cwj pwm los ntawm kev sib cuag me me voltage, tsis kam coefficient thiab hluav taws xob poob. Cov txhuam hniav no tsuas yog siv rau qis-voltage loj tam sim no motors thiab qis-voltage AC winding motors.

Ntuj graphite txhuam thiab electroextburra txhuam resistor coefficients thiab txhuam siab tee yog loj, ntau abrasion resistant, thiab cov kab nrawm raug tso cai siv (tuaj yeem ncav cuag 50 ~ 70m / s). Hlau graphite txhuam resistor coefficient thiab txhuam hluav taws xob txo qis, thiab kev puas tsuaj tsis zoo. Txoj kab ceev tso cai siv yog tsawg. Txog 15 ~ 35m / s.

2. Kev ua tau zoo
Cov khoom tseem ceeb ntawm cov tshuab txhuam hniav muaj xws li cov resistors, hardness, hardness ntawm ib nkawm txhuam, txhuam coefficients, 50H hnav, thiab lwm yam. Cov coefficient kuj yog ib lub cev kom muaj nuj nqis los ntsuas qhov kev ua tau zoo. Ntawm 230V, cov hluav taws xob txhuam hluav taws xob tuaj yeem xaiv qhov loj dua, thiab 120V txhuam resistor coefficient yuav tsum me dua. Hluav taws xob 120V lub cev muaj zog tam sim no nrog tib lub zog loj dua 230V. Cua sov, tuav qhov kub thiab txias yuav yog super phem.

The contact voltage drop of a pair of brushes is the difference in the potential difference between the current flowing into the brush through the switch to the brush. When the brush is in contact with each other, and the resistance of the contact surface when the contact surface occurs under the action of external forces, it is called friction. The ratio of friction and spring pressure is the friction coefficient of the brush and the directioner. 50H wear value: Under the specified experimental conditions, the brush is determined by the current density and the prescribed unit pressure. When the transitional line speed is 15m/s, the amount of wear of the brush is grinded by 50h.
