Brushless vs Brushed Circular Cold Saws: Kusiyana kwake ndi Chiyani?

N'chifukwa Chiyani Chozungulira Chitsulo Chimatchedwa Cold Saw?

Macheka ozizira ozungulira amalola kuti zinthu zonse ndi tsamba likhalebe lozizira panthawi yocheka potengera kutentha komwe kumachokera ku tchipisi.

Macheka achitsulo ozungulira, kapena macheka ozizira, ndi makina ocheka omwe amadula zipangizo ndi zitsulo zothamanga kwambiri (HSS) carbide kapena cermet-nsonga, macheka ozungulira. Masamba ang'onoang'ono ang'onoang'ono amadziwika ngati masamba a njira imodzi chifukwa amachotsedwa akayamba kuzimiririka. Masamba okulirapo amatha kuwongoleredwanso ndikugwiritsiridwa ntchito kangapo.

Masamba a macheka ozizira amadula zinthu mothamanga kwambiri kuti apange chiphuphu chochuluka pa dzino. Macheka ozizira safuna zoziziritsa kukhosi chifukwa kutentha kobwera chifukwa cha kudula kumasamutsidwa kupita ku tchipisi. Ma chips amatulutsidwa ndi mphamvu yapakati pa tsamba lozungulira. Izi zimathandiza kuti tsamba ndi zinthu zodulidwa zikhale zoziziritsa, choncho dzina la "macheka ozizira" -koma samalani ndi chips. Malingana ndi aloyi, amatha kukhala otentha otentha.

Macheka Ozizira vs. Macheka Otentha

Macheka otentha ndi m'malo mwa macheka ozizira. Macheka a friction ndi ma abrasive macheka amaonedwa kuti ndi macheka otentha chifukwa cha zochita zawo zowotcha. Mano amadula zinthu popanga kugundana kwa tsamba lozungulira. Izi kudula kanthu amasungunula zinthu pamene oxidizing ndi kuwotcha kutali. Abrasive macheka ndi ofanana kwambiri ndi macheka mkangano kupatula zakuthupi kamakhala abraded mu mawonekedwe akupera fumbi. Kudula kwa abrasive kumakulitsa tsamba ndi zinthu zomwe zikudulidwa, kutulutsa kutentha kwambiri chifukwa cha kukangana, ndikuwonjezera kuvala kwa masamba ndi kugwiritsa ntchito mphamvu.

Monga katswiri pamakampani opanga zida, mwina mudakumanapo ndi mkangano wokhudzana ndi ma brushless ndi ma brushless motors mu zida zamagetsi. Funso limabuka nthawi zambiri: "Kodi zida zopanda maburashi zili bwino kuposa zopukutira?" Mu positi iyi yabulogu, tifufuza mozama za injini yopanda maburashi, ubwino ndi kuipa kwa zida zopanda maburashi, ndi zochitika zenizeni zomwe ma motors opanda brush amawala. Mawu akuti "brushless" amatanthauza ukadaulo wa mota womwe umagwiritsidwa ntchito pa macheka.

Kodi Brushless Motor ndi chiyani?

Galimoto yopanda maburashi, monga momwe dzina limatchulira, imagwira ntchito popanda maburashi. Ma motors achikhalidwe amagwiritsa ntchito maburashi a kaboni kusamutsa magetsi, kupanga mikangano ndi kutentha. Mosiyana ndi izi, ma motors opanda maburashi amagwiritsa ntchito chowongolera chamagetsi kuti azitha kuyendetsa bwino zomwe zikuchitika, zomwe zimachepetsa kung'ambika ndi kung'ambika, zimathandizira magwiridwe antchito, komanso zimawonjezera magwiridwe antchito.

Ubwino wa Brushless Motors

1.Kuwonjezera Kuchita Bwino:Ma motors opanda maburashi ndi othandiza kwambiri kuposa ma motors opukutidwa, chifukwa amatulutsa kutentha pang'ono panthawi yogwira ntchito ndipo amachepetsa kutayika kwa mphamvu chifukwa cha kukangana. Kuchita bwino kumeneku kumabweretsa moyo wautali wa batri (ngati mulibe zingwe) komanso kupsinjika kochepa pa chida.

2. Higher Power-to-weight Ration:Ma motors opanda maburashi amakhala amphamvu kwambiri poyerekeza ndi kukula kwake ndi kulemera kwawo, zomwe zimapereka magwiridwe antchito bwino pamaphukusi ophatikizika komanso opepuka.

3.Kusamalira Kochepa:Popeza palibe maburashi kuti atha, ma motors opanda brush amafunikira kusamalidwa pang'ono, zomwe zimapangitsa moyo wautali wa zida ndikuchepetsa nthawi.

4. Kuchita bwino:Macheka ozungulira opanda maburashi amapereka magwiridwe antchito abwino komanso ma torque apamwamba, kuwalola kugwira ntchito zodula kwambiri.

5. Kuchita bwino:Ma motors opanda maburashi amatha kuwongolera liwiro, zomwe zimapangitsa kuti zikhale zosavuta kudula komanso kudula koyeretsa.

Zoyipa za Brushless Motors

Chimodzi mwazovuta zazikulu zama motors opanda brush ndi mtengo wawo wokwera poyerekeza ndi zida zopukutidwa. Zipangizo zamakono zamakono komanso kupanga zinthu zimapangitsa kuti zikhale zodula. Komabe, mtengowu ukhoza kuthetsedwa ndi moyo wawo wautali komanso kuchepetsa zosowa zawo.

Ma motors opanda maburashi nawonso ndi ovuta kwambiri kuposa ma motors opukutidwa, omwe amatha kupanga kukonzanso kukhala kovuta komanso kokwera mtengo ngati atawonongeka. Chidziwitso chapadera ndi zigawo zingafunike.

Kodi Pali Zochitika Zomwe Zida Zopanda Maburashi Sizofunika?

Ngakhale ma motors opanda maburashi amapereka zabwino zambiri, sizingakhale zofunikira nthawi zonse pantchito iliyonse kapena wogwiritsa ntchito. Kwa okonda DIY wamba kapena ntchito zomwe sizifuna mphamvu zambiri kapena kulondola, ma motors opukutidwa amatha kukhala chisankho chotsika mtengo. Zida zopukutidwa nthawi zambiri zimakhala zokwanira kugwiritsa ntchito zopepuka komanso zimapereka mtengo wocheperako.

Ndiye, kodi zida zopanda brush zili bwino kuposa zopukutira? Kwa akatswiri ambiri, yankho lake ndi inde. Ubwino wa ma motors opanda brush pakuchita bwino, mphamvu, kukonza pang'ono, komanso moyo wautali zimawapangitsa kukhala chisankho chapamwamba pamapulogalamu ambiri. Komabe, kukwera mtengo ndi zovuta sizingakhale zomveka kwa ogwiritsa ntchito wamba kapena ntchito zopepuka.HERO, timapereka macheka ozizira opanda brush kuti akwaniritse zofuna za akatswiri omwe akufuna kudalirika ndi ntchito.

Mukamagwiritsa ntchito macheka ozungulira, nthawi zonse tsatirani malangizo achitetezo, valani zida zodzitetezera zoyenera, ndipo onetsetsani kuti mukuzidziwa bwino momwe chidacho chimagwirira ntchito. Ndikofunikira kugwiritsa ntchito tsamba loyenera pazinthu zomwe mukudula ndikusamala kuti mupewe ngozi kapena kuvulala.

Chitetezo Choyamba:Tisanadumphe m'zinthu zothandiza zogwiritsira ntchito macheka ozungulira opanda brush, tiyeni titsindike kufunikira kwa chitetezo. Nthawi zonse valani zida zodzitetezera (PPE), kuphatikiza magalasi otetezera makutu, zotchingira makutu, ndi zotchingira fumbi. Onetsetsani kuti mukugwira ntchito pamalo olowera mpweya wabwino komanso malo ogwirira ntchito omveka bwino komanso opanda zosokoneza. Werengani bukhuli mosamala ndipo dziwani njira zotetezera zomwe zili pachidacho.

Sonkhanitsani ndi Kuyang'ana:Ngati muli ndi macheka ozungulira opanda maburashi, onetsetsani kuti chingwe chamagetsi chili bwino ndipo cholumikizidwa bwino pamalo otsika. Pamitundu yopanda zingwe, yambani batire mokwanira musanagwiritse ntchito. Ikani tsamba loyenera la zinthu zomwe mukufuna kudula, ndipo onetsetsani kuti ndi lotetezeka komanso lakuthwa. Yang'anani macheka kuti muwone kuwonongeka kulikonse kapena zotayirira musanayatse.

Sinthani Kuzama ndi Kucheka:Masamba ambiri ozungulira opanda brush amakulolani kuti musinthe kuya kwa kudula ndi kudula. Khazikitsani kuya kwa kudula molingana ndi makulidwe azinthu zomwe mukugwira nazo ntchito. Masulani lever yosinthira kuya, sinthani mbale yoyambira, ndiyeno limbitsaninso lever. Kuti musinthe ngodya yodulira, masulani lever yosinthira bevel, sinthani sikeloyo kuti ifike pamlingo womwe mukufuna, ndiyeno limbitsaninso lever.

Mayesero Amakhala Angwiro:Ngati mwangoyamba kumene kugwiritsa ntchito macheka ozungulira, yesani pazidutswa za zinthu musanagwire ntchito yanu yayikulu. Dziwani kulemera kwa chida, kusanja, ndi kusuntha kwa chipangizocho. Izi zidzakuthandizani kukhala ndi chidaliro ndikuwongolera kulondola kwa kudula.

Kugwiritsa ntchito macheka ozungulira opanda brushless kumafuna kukhazikitsidwa koyenera, kumvetsetsa mawonekedwe ake, ndikutsatira njira zodzitetezera. Ndikuchita komanso kuleza mtima, mutha kudziwa njira zosiyanasiyana zodulira ndikukwaniritsa ntchito zanu zodulira moyenera komanso molondola. Kumbukirani kuika patsogolo chitetezo nthawi zonse ndipo musazengereze kufunafuna chitsogozo kwa ogwiritsa ntchito odziwa zambiri kapena akatswiri pakafunika. Wodala kudula.
