Choyamba, ndiloleni ndifotokoze bwino lingaliro

Chomwe timachitcha kuti "mota ya brush ya kaboni" ndi "mota ya brush" m'munda wa ma micro water pumps chimatanthauza mtundu womwewo wa mota -- mota ya brush ya DC, yomwe imagwiritsa ntchito burashi ya kaboni (burashi) kuti ilumikizane ndi commutator kuti itsogolere magetsi ndikusintha njira ya mphamvu ya maginito.
Ndipo otsutsana naye, ndi kudzera mu kusintha kwa magetsi kwamota ya DC yopanda burashiulamuliro.

Kuti timvetse bwino kusiyana kwawo kwakukulu, titha kufananiza mwachangu poyang'ana tebulo lotsatirali:

1. Mota ya burashi ya kaboni: chisankho chachikale komanso chotsika mtengo

 

Ma mota a carbon brush, omwe amadziwikanso kuti ma mota a DC brushed, ndi njira zamakono zoyendetsera zinthu zakale kwambiri.

Mfundo Yogwirira Ntchito
Pakatikati pali ziwirimaburashi a kaboni(yopangidwa ndi graphite ndi chitsulo) ngati zolumikizira zokhazikika, zokhala ndi zozungulirapepala loyenderapa rotor ya injini, kulumikizana kosalekeza, kotero kuti njira yamagetsi imasinthidwa nthawi zonse, kotero kuti rotor ipitirire kuzungulira.

Zinthu Zofunika Kwambiri:

1 Ubwino:

Mtengo Wotsika: Kapangidwe kosavuta, ukadaulo wokhwima, mtengo wopanga ndi wotsika kwambiri kuposa mota yopanda burashi, zomwe zimapangitsa kuti mtengo wonse wa pampu ukhale wopikisana kwambiri.

 

Kulamulira Kosavuta：Liwiro ndi mphamvu zimatha kusinthidwa mosavuta posintha magetsi kapena mphamvu, monga kugwiritsa ntchito njira yosavuta yowongolera liwiro la PWM, popanda kufunikira ma circuits ovuta kuyendetsa.

2.KulepheraMoyo wochepa: Ichi ndiye vuto lalikulu la mota ya burashi ya kaboni. Burashi ya kaboni imatha kugwiritsidwa ntchito ndipo imawonongeka pang'onopang'ono ikakangana ndi commutator kwa nthawi yayitali. Ikakanika, motayo imalephera kugwira ntchito. Chifukwa chake, moyo wa mota ya burashi ya kaboni nthawi zambiri umakhala pakati pa maola mazana angapo mpaka zikwi zingapo.

3. Kusokoneza kwa maginito kudzapangidwa:Burashi ya kaboni ndi commutator zimapanga ma spark amagetsi panthawi yokhudzana ndi kulekanitsidwa, zomwe zingayambitse kusokoneza kwa ma electromagnetic ku zida zamagetsi zozungulira.

4.Kugwiritsa ntchito bwino kochepa:Chifukwa cha kukana kukangana ndi kukana kukhudzana kwa burashi ya kaboni, mphamvu imatayika kwambiri, ndipo nthawi zambiri mphamvu zake zimakhala zochepa kuposa za ma mota opanda brush.

5. Phokoso:Kukangana kwa burashi ya kaboni ndi spark kumabweretsa phokoso linalake la ntchito.

2-Injini yopanda burashi: chisankho chamakono cha magwiridwe antchito apamwamba

Mota yopanda burashiikuyimira njira yaukadaulo yapamwamba komanso yothandiza kwambiri.

Mfundo Yogwirira Ntchito：
Zimaletsa kukhudzana kwenikweni pakati pa burashi ya kaboni ndi commutator. M'malo mwake,chowongolera zamagetsiimagwiritsidwa ntchito kuzindikira malo a rotor ndikuwongolera molondola momwe mphamvu imagwirira ntchito komanso nthawi ya ma stator coils, motero kuyendetsa rotor kuti izungulire. Uku ndi kusintha kwa "electronic" osati "mechanical".

Mbali Yaikulu：

Ubwino：

Kutalika kwa moyo：Popeza palibe ziwalo zolumikizirana zakuthupi zomwe ziyenera kuvala, moyo wake umadalira kokha kuwonongeka kwa bearing, nthawi zambiri mpaka maola masauzande ambiri, zomwe ndi nthawi khumi kapena ngakhale makumi a moyo wa mota ya carbon burashi.

Kugwiritsa ntchito bwino kwambiri, kugwiritsa ntchito mphamvu zochepa：Palibe kutayika kwa kukhudzana ndi makina ndipo mphamvu yosinthira mphamvu ndi yokwera, zomwe zikutanthauza kuti imasunga magetsi ambiri kapena ingapereke mphamvu yochulukirapo pamagetsi omwewo.

Mawu otsika：Palibe phokoso la kukangana kwa burashi ya kaboni, kuti muthamange mwakachetechete.

Palibe kusokoneza kwa ma elekitiromagineti:Palibe vuto la EDM, ndi losavuta kugwiritsa ntchito pamakina amagetsi osavuta kugwiritsa ntchito.

Kulamulira kwakukulu:Ikaphatikizidwa ndi chowongolera chanzeru, imatha kukwaniritsa ntchito zapamwamba monga kuwongolera liwiro molondola, chitetezo cha rotor chotsekedwa, komanso kutulutsa chizindikiro cha mayankho.

Zoyipa:

Mtengo wokwera:Kapangidwe ka injini ndi chowongolera choyendetsera chofunikira ndi chovuta kwambiri kuposa cha ma mota a carbon brush, zomwe zimapangitsa kuti ndalama zonse zikhale zokwera3.

Kulamulira kovuta:Iyenera kudalira chowongolera chodzipereka kuti igwire ntchito ndipo singazungulire mwachindunji ikayendetsedwa ngati mota ya burashi ya kaboni.

Kodi mungasankhe bwanji zochitika zogwiritsira ntchito?

Mukadziwa mawonekedwe awo, chisankhocho chimawonekera bwino:

Sankhani Pumpu Yopanda Brush Motor ngati:

Mtengo ndiye chinthu chofunikira kwambiri kuganizirandipo bajeti ya polojekitiyi ndi yochepa kwambiri. Zipangizo zake ndi zanthawi inakapenam'masiku ochepa patsogolokapena imagwiritsidwa ntchito kawirikawiri.Phokoso, kusokoneza kwa maginito, ndi moyo wautalisizofunikira kwenikweni. Kulamulira liwiro kosavuta kwambiri n'kofunika.

Mapulogalamu Odziwika:Akasupe otsika mtengo a patebulo, madzi osavuta kuyenda, zitsanzo zowonetsera zinthu zomwe zingatayike, ndi zoseweretsa zotsika mtengo.

Sankhani pampu ya "mota yopanda brushless" pamene:

Kudalirika ndi moyo wautali ndiye zofunika kwambiri.Zipangizozi ziyenera kugwira ntchito bwino kwa nthawi yayitali. Zimagwiritsidwa ntchito m'malo omwe ali ndi vuto lakusokoneza kwa maginito, monga zida zachipatala, zida za labotale, pafupi ndi makina amawu a hi-fi. Amafunikantchito ya phokoso lochepamonga zipangizo zapakhomo, malo osungiramo zinthu zoziziritsa kukhosi okhala chete, ndi zida zaofesi. Kugwiritsa ntchito bwino mphamvu ndikofunikira, makamaka pazida zonyamulika zomwe zimagwiritsa ntchito batire.Kulamulira kwanzeruchofunika, monga kulumikizana ndi makompyuta ang'onoang'ono okhala ndi chip chimodzi ndi kuwongolera kayendedwe ka madzi molondola, ndi zina zotero.

Ntchito wamba:zida zoyezera matenda azachipatala, makina a khofi, zotsukira madzi zapamwamba, zamagetsi zamagalimoto, mapampu oyendera madzi m'madzi a m'nyanja omwe amakhala nthawi yayitali, makina opopera mpweya opanda anthu m'mlengalenga, ndi zina zotero.

chidule

Mwachidule, kusankha mota ya burashi ya kaboni ndi mota yopanda burashi mkati mpope yaying'ono ya diaphragmkwenikweni ndi kusinthana pakati pa"mtengo" ndi "magwiridwe antchito".

Ma mota a burashi ya kaboni, ndi ubwino wawo waukulu pamtengo komanso kuwongolera kosavuta, akadali ndi udindo wofunikira pamsika woganizira kwambiri za mitengo.

Mota yopanda burashindi zakekudalirika kwambiri, moyo wautali komanso magwiridwe antchito abwino kwambiri,chakhala chida chachikulu kwambiri pa mapulogalamu amakono apamwamba komanso ofunikira kwambiri. Ndikukhulupirira kuti nkhaniyi ikuthandizani kusankha bwino ukadaulo.
