Pahu Kalapona no ke kaa

Kapa ʻia nā pulupulu he palaki kalapona i nā mea uila. He mea ia o ke kaʻa. Ma waho aʻe o ka hoʻopili ʻana i ka electrone a me ke kaapuni waho i loko o ka kaʻa, hoʻokani pū ia i ke ʻano o kahi au. Hoʻokumu ʻia kahi loulou nāwaliwali a koʻikoʻi o ke kaʻa e ka palaki me ka mea kuhikuhi. ʻAʻole wale ka lole mechanical a me ka vibration mechanical ma waena o ka pulupulu a me ka mea kuhikuhi, akā he ʻālohilohi koʻikoʻi hoʻi i ka manawa o ka hoʻohana ʻana, e hōʻemi loa i ke ola o ka wiper, akā pili pū kekahi i ka hana maʻamau o ka kaʻa. No laila, ʻo ke koho kūpono o nā mea pulupulu, ka nui a me ke kaomi puna, e pāʻani i kahi hana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka hana kuhikuhi o ka kaʻa a hoʻonui i kona ola lawelawe.

ʻO ke kohoʻana o ka pulupulu ma muli o ka piʻiʻana o ka mahana o ka'ōpala, a ua hoʻoholoʻia ke kuhikuhi o ke kuhikuhi. ʻO ka piʻi ʻana o ka mahana o ka pulupulu e pili ana i ka nui o ka bristle me ka nui o ka pili kuhikuhi, ka nalowale mechanical a me ka conductivity thermal o ka pulupulu. Inā kiʻekiʻe ka wikiwiki o ka laina pōʻai, ua maʻalahi ka wela i ka pulupulu a me ke kuhikuhi, e piʻi aʻe ka uila, a ua hoʻonui ʻia ka ʻaʻahu o ka pulupulu a me ka wiper.
ʻO ka hoʻomaka ʻana i ke ʻano, ka hoʻokaʻawale ʻana a me ka hana ʻana o ke kalapona kalapona kaʻa
Mai ka hiʻohiʻona o ka hoʻohana ʻana, aia ka nui o nā hōʻailona o ka hoʻohana ʻana i nā pulupulu maikaʻi: nā kūlana aʻe:

1) Ke holo nei ka pulupulu, wela, walaʻau, ʻaʻohe pōʻino, ʻaʻohe kala, ʻaʻole wela;

2) Loaʻa i ka hana alakaʻi maikaʻi, keʻakeʻa i ka ʻulaʻula ma ka laulā i ʻae ʻia, a liʻiliʻi ka nalowale o ka ikehu;

3) ʻO ke ola lōʻihi o ka lawelawe ʻana a ʻaʻole e ʻaʻahu i kahi wiper, mai hana i ka wiper e ʻohi, ʻole ʻole, ʻā, kiʻi, etc.;

4) I ka wā o ka hana, hiki ke hoʻokumu koke ʻia kahi kiʻi ʻoniʻoni ʻoniʻoni ʻoniʻoni, haʻahaʻa, a paʻa i ka ʻili o ka mea kuhikuhi.


ʻO ke ʻano o ka pulupulu
ʻO ke kuhikuhi o ka hoʻokomo ʻana o ka pulupulu o ka graphite brush: ʻano radial, hoʻi hope a me mua -tilt. I loko o ka hana radial maʻamau, ʻokoʻa ke kaomi o ka pūnāwai. Aia ka nui o nā pūnāwai laina pūnana, nā pūnāwai spiral, a me ka pūnāwai kikoo. ʻO kēia mau ʻano kaomi puna ʻekolu e hana pololei i ka pulupulu ma ke kaomi ʻana o ka puna; Kuʻuna

Hoʻokaʻawale a me ka hana ʻana o ka pulupulu

1. Hoʻokaʻawale
Hoʻokaʻawale ʻia nā pulupulu e like me kā lākou embryo material composition a me ke kaʻina hana lapaʻau

a. Palaki kalapona kalapona

ʻO ka pulupulu graphite maoli: ʻo ia mau pulupulu he kiʻekiʻe ka pilina pili, hana hoʻoponopono maikaʻi, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka uila graphite brush, hana lubrication maikaʻi, a hoʻohana ʻia no nā laina kiʻekiʻe me nā laina laina kiʻekiʻe.

ʻO Resin bonding graphite brush: ʻO kēia ʻano o ka pulupulu e hōʻike ʻia e ke kūpaʻa nui, hoʻemi ʻia ka uila pili, ka hana hoʻololi maikaʻi, antioxidant, a me ke kūpaʻa abrasion he mea kūpono, akā hoʻohana nui ʻia ka hoʻohana ʻana i ka mana i nā kaʻa kahe AC.

b. Palaki graphite electrifying

Graphite-based brush (palapala palupalu): Ua hōʻike ʻia e nā coefficient friction haʻahaʻa, hana lubrication maikaʻi, hana hoʻonohonoho maikaʻi, kūpaʻa wela, a me ka hana antioxidant; nā kaʻa huila nui me nā laina laina kiʻekiʻe aʻe a me nā haʻawe hopena koke ʻO nā kaʻa kaʻa kaʻa nui, a me nā mīkini DC liʻiliʻi a liʻiliʻi;

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;

Palaki ʻīnika kalapona (palaki paʻakikī): No kēia ʻano pulupulu no ka pulupulu kūpaʻa kiʻekiʻe no ka pulupulu graphite electro-chemical. Hōʻike ʻia ia e ke kūpaʻa pili palaki nui a me ka hana kuhikuhi maikaʻi. Hoʻohana ʻia ia no nā motika DC me ka paʻakikī i ka hoʻololi ʻana i ke ala.

c. Papa graphite palaki metala
He metala a me ka graphite. Hoʻololi ʻia nā ʻano o ka metala a me ka graphite e nā ʻano o ka conductivity metala maikaʻi a me ka lubrication lubrication maikaʻi. Hōʻike ʻia ia e ka liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi, koena kūʻē a me ka nalowale uila. Hoʻohana nui ʻia kēia pulupulu no nā kaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me nā kaʻa uila uila haʻahaʻa haʻahaʻa.

Natural graphite brush and electroextburra brush resistor coefficients and brush pressure drops are large, more abrasion resistant, and the line speeds are allowed to be used (can reach 50 ~ 70m/s). Metal graphite brush resistor coefficient and brush voltage decreases less, and the abrasion resistance is poor. The line speed allowed to use is low. About 15 ~ 35m/s.

2. Hana
ʻO nā mea nui o ka ʻenehana palaki e pili ana i nā resistors, paʻakikī, paʻakikī ma luna o kahi pālua o nā brushes, friction coefficients, 50H wear, etc. Ma ka 230V, hiki ke koho nui ʻia ka ʻāpana pale pale uila, a ʻoi aku ka liʻiliʻi o ka 120V brush resistor coefficient. ʻOi aku ka nui o nā ʻauwai uila 120V me ka mana like ma mua o 230V. ʻO ka wela, ʻoi aku ka maikaʻi o ka wela o ka paʻa.

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.
