Le Mea ma le Taua o Pumu Kaponi

 

pulumu kaponior electric brushes are widely used in electrical equipment. They are used to transmit signals or energy between the fixed part and the rotating part of some motors or generators. The shape is rectangular, and metal wires are installed in the spring. Carbon brushes are a kind of sliding contact, so it is easy to wear and needs to be replaced regularly and the carbon deposits that have been worn away must be cleaned.

 

O le vaega autu o le pulumu carbon o kaponi. A galue, e oomiina e se puna e galue i luga o le vaega taamilo e pei o se pulumu, ona ta'ua lea o le pulumu kaponi. Ole mea autu ole graphite.

 

Graphite o se elemene faanatura, o lona autu vaega o le carbon, o le lanu e uliuli, opaque, luster semi-metallic, maualalo maaa, e mafai ona pikiina i atigilima, graphite ma taimane e lua carbon, ae o latou meatotino e matua ese lava, e mafua ona o le eseese faatulagaga o kaponi atoms. E ui lava o le tuufaatasiga o le graphite o le carbon, ae ose mea e tete'e i le vevela ma le mea liusuavai o le 3652°C. Fa'aaogaina lenei mea maualuga le vevela tete'e meatotino, graphite e mafai ona gaosia i se u'amea kemikolo e tetee i le vevela maualuga.

 

O le conductivity eletise o graphite e lelei tele, e sili atu i le tele o metala ma faaselau taimi nai lo mea e le o ni uamea, o lea ua gaosia i vaega conductive e pei o electrodes ma pulumu carbon; o le fausaga totonu o le graphite e fuafua ai lona lubricity lelei, ma tatou masani fa'aoga i faitoto'a elea O le tu'uina o le pefu penitala po'o le kalafi i totonu o le loka e mafai ai e faigofie ona tatala le faitotoa. E tatau ona avea lea ma aafiaga lubricant o le graphite.

 

pulumu kaponie masani ona faʻaaogaina i DC mea tau eletise. O masini pulumu e aofia ai le stator ma le rotor. I totonu se afi DC, ina ia mafai ai ona sui le rotor, le itu o le taimi nei e tatau ona suia i taimi uma, a leai e mafai e le rotor na o le afa a li'o. E taua tele le sao o pulumu carbon i masini DC. pulumu kaponi fa'afoe le taimi nei i le va o vaega fe'avea'i o le afi. O lenei fa'agasolo o se fa'ase'e fa'atonuga e mafai ona fa'afeiloa'i le taimi nei mai le pito fa'amau i le vaega taamilo o le afi afi po'o le afi. O se fa'avaa kaponi e fa'avae i ni pulumu kaponi, O lea la, o lenei auala fa'aoso e faigofie ai fo'i ona ofuina pulumu kaponi, ma le e suia foi e pulumu carbon le itu o le taimi nei, o lona uiga, o le matafaioi a feoaiga.

 

O le masini pulumu e faʻaaogaina masini commutation, e le minoi le pou mageta pito i fafo ma le vili totonu. A galue le afi, o le commutator ma le coil e taamilo faatasi, ma le pulumu kaponi ma le uamea maneta e le gaoioi, o lea o le commutator ma le o le pulumu kaponi e maua ai le fete'ena'iga e fa'amae'a ai le suiga o le taimi nei faasinomaga.

 

A'o taamilo le afi, eseese coils po'o e lua laasaga eseese o le uʻamea tutusa e faʻamalosia, ina ia lua pou o o le maneta e gaosia e le coil o loʻo i ai se tulimanu faʻatasi ai ma pou e lua e vavalalata i le stator maneta tumau, ma o le malosiaga e gaosia e ala i le teena o le pou lava e tasi ma le faatosina o le faafeagai pou e tulia le afi e taamilo.

 

pulumu kaponio loʻo faʻaaogaina foi i le AC meafaigaluega. Le foliga ma mea o le AC moto carbon brushes ma DC afi e tutusa lava pulumu kaponi. I afi AC, e faʻaaogaina pulumu carbon pe a fai nisi e mana'omia e rotors fe'avea'i le saoasaoa fesuisuia'i, e pei o a tatou fa'aoga eletise e masani ona fa'aaogaina ma masini fa'alelei, ma e mana'omia ona sui soo pulumu kaponi.
