Masale a carbon brush slip rings a sebetsa joang tsamaisong ea satellite ea puisano?

Sebakeng sa litsamaiso tsa puisano tsa sathelaete, mehele ea khabone e thellang e bapala karolo ea bohlokoa empa hangata e hlokomolohuoa. Joaloka mofani oa thepa ea boleng bo holimo - ba liringche tsa carbon brush slip rings, ke thabetse ho batlisisa ka har'a ts'ebetso e rarahaneng ea likarolo tsena le ho hlalosa hore na li kenya letsoho joang ts'ebetsong e tsitsitseng ea puisano ea sathelaete.

Mehele ea "carbon brush slip" ke lisebelisoa tsa electromechanical tse etselitsoeng ho fetisa matla a motlakase, matšoao, kapa data lipakeng tsa karolo e emeng le e potolohang ea sistimi. Boemong ba puisano ea sathelaete, li bohlokoa bakeng sa ho nolofalletsa puisano e tsoelang pele ha likarolo tsa sathelaete li ntse li potoloha, joalo ka antenna kapa liphanele tsa letsatsi.

Sebopeho sa motheo sa selikalikoe sa carbon brush se na le likarolo tse peli tse kholo: selikalikoe sa slip le brush ea carbon. Lesale le thellang ke selikalikoe sa conductive se potolohang le karolo e tsamaeang ea sistimi ea sathelaete. Hangata e entsoe ka thepa e tsamaisang haholo joalo ka koporo kapa koporo. Ka lehlakoreng le leng, brashi ea k'habone ke karolo e emeng e entsoeng ka carbon kapa carbon - composite material. Carbon brush e hatelloa khahlano le selikalikoe sa slip, ho theha khokahano ea motlakase.

Matla ke bophelo ba tsamaiso efe kapa efe ea puisano ea sathelaete. Ho tloha ho matlafatsa li-transceivers tsa puisano ho ea ho li-sensor tse fapaneng tse ka sekepeng, phepelo e tšepahalang ea motlakase e bohlokoa. Li-ring slip rings tsa carbon ke tsa bohlokoa ho netefatsa hore matla a motlakase a ka fetisoa ho tloha mohloling oa matla oa sathelaete (hangata liphanele tsa letsatsi) ho ea ho likarolo tse potolohang.

Ha liphanele tsa letsatsi tsa sathelaete li hlahisa motlakase, matla ana a lokela ho fetisetsoa likarolong tse potolohang tsa sathelaete, tse kang antenna. Mehele ea khabone ea brush slip e sebetsa e le borokho bakeng sa phetiso ena ea matla. Ha selikalikoe sa slip se ntse se potoloha, brashi ea carbon e boloka khokahanyo e sa khaotseng ea motlakase le eona. Motlakase oa motlakase o phalla ho tloha mohloling oa matla ka brush ea carbon le ho kena ka har'a reng ea ho thella, ebe o ea karolong e potolohang e hlokang matla. Phetisetso ena e tsoelang pele ea matla e bohlokoa bakeng sa tšebetso e nepahetseng ea lisebelisoa tsa puisano ho sathelaete.

Ntle le phetisetso ea matla, mehele ea carbon brush slip e boetse e ikarabella bakeng sa ho fetisa matšoao le data. Litsamaiso tsa puisano tsa satellite li itšetlehile ka phapanyetsano ea boitsebiso bo bongata, ho akarelletsa le lentsoe, video le matšoao a data. Matshwao ana a hloka ho fetiswa pakeng tsa dikarolo tse emeng le tse potolohang tsa sathelaete ntle le tahlehelo kapa tshitiso efe kapa efe.

Li-rings tsa carbon brush slip li etselitsoe ho sebetsana le mefuta e fapaneng ea lipontšo. Bakeng sa mats'oao a - a tlase, khokahano ea motlakase lipakeng tsa brashi ea khabone le selikalikoe sa slip e netefatsa phetiso e tsitsitseng. Tabeng ea mats'oao a holimo a -, ho nahanoa ka moralo o khethehileng ho fokotsa tahlehelo ea mats'oao le ho kena-kenana le motlakase. Ka mohlala, lisebelisoa tse sebelisoang ka har'a selikalikoe sa slip le brush ea carbon li khethiloe ka hloko hore li be le matla a fokolang a motlakase le thepa e ntle ea ho sireletsa motlakase.

Ho na le mabaka a 'maloa a etsang hore mehele ea carbon brush e le khetho e ratoang bakeng sa mekhoa ea puisano ea sathelaete. Taba ea pele, k'habone e na le conductivity e ntle ea motlakase, e lumellang matla a sebetsang hantle le phetisetso ea matšoao. E boetse e na le mekhoa e metle ea ho itlotsa ka -, e fokotsang ho senyeha le ho taboha holim'a selikalikoe sa slip le brush ea carbon, e lelefatsang nako ea bophelo ea sesebelisoa.

Taba ea bobeli, mehele ea khabone ea brashi e bonolo ka moralo ebile e bonolo ho e etsa. Sena se etsa hore li bitse - hantle ha li bapisoa le mefuta e meng ea li-slip rings. Li ka boela tsa etsoa ka mokhoa o ikhethileng ho fihlela litlhoko tse khethehileng tsa mekhoa e fapaneng ea puisano ea sathelaete. Ka mohlala, ho itšetlehile ka litlhoko tsa matla le mofuta oa matšoao a lokelang ho fetisoa, boholo, sebōpeho, le thepa ea mehele ea carbon brush slip e ka fetoloa.

Joalo ka morekisi oa lesale la carbon brush slip, re fana ka lihlahisoa tse fapaneng tse loketseng lits'ebetso tsa puisano tsa sathelaete. E 'ngoe ea lihlahisoa tsa rona tse tsebahalang keSlip Ring Ka Rotor e Arohileng le Carbon Brush. Mofuta ona oa lesale la ho thella o entsoe ka rotor e arohaneng le brashi ea carbon, e fanang ka phetoho e kholo ea ho kenya le tlhokomelo. E loketse lits'ebetso moo karolo e potolohang e hlokang ho qhaqhoa habonolo le ho kopanngoa hape.

Sehlahisoa se seng ke600A le 30A High Power Carbon Brush Slip Ring. Lesale lena le phahameng - la ho thella ha motlakase le khona ho sebetsana le motlakase o mongata, ho etsa hore e lokele lisebelisoa tsa sathelaete tse lapileng -. E entsoe ka thepa ea boleng bo holimo - ho netefatsa phetiso e tšepahalang ea matla le tlas'a maemo a feteletseng.

Re boetse re fana kaCarbon Brush e nang le Mehele ea Copper Contacting Slip. Motsoako oa li-brushes tsa carbon le mehele ea koporo ea koporo e fana ka conductivity e ntle ea motlakase le ho tšoarella. Koporo e tsejoa ka conductivity ea eona e phahameng, 'me ha e kopantsoe le borashe ba carbon, e ka fetisa matla le lipontšo ka mokhoa o atlehileng tsamaisong ea puisano ea sathelaete.

Leha mehele ea khabone e thellang e fana ka melemo e mengata, e boetse e tobana le liphephetso lits'ebetsong tsa puisano tsa sathelaete. E 'ngoe ea liqholotso tse ka sehloohong ke ho senyeha. Ha nako e ntse e ea, khohlano e teng lipakeng tsa brashi ea khabone le selikalikoe se thellang ho ka etsa hore brashi ea khabone e senyehe, e leng se ka lebisang ho se sebetse hantle ha motlakase le tahlehelo ea matšoao.

Ho rarolla bothata bona, re sebelisa lisebelisoa tse tsoetseng pele le mekhoa ea tlhahiso. Mohlala, re apesa lesale la ho thella ka lesela le thata - ho fokotsa ho hohlana le ho lelefatsa bophelo ba borashe ba k'habone. Re boetse re etsa tlhahlobo ea kamehla ea taolo ea boleng ho netefatsa hore mehele ea khabone e thellang e fihlela maemo a holimo.

Bothata bo bong ke tikoloho e thata ea sebaka. Lisathelaete li pepesehetse mocheso o feteletseng, mahlaseli a kotsi le maemo a lehloeo. Lintlha tsena li ka ama ts'ebetso ea mehele e thellang ea carbon brush. Ho hlola sena, re rala mehele ea rona ea li-slip ka lisebelisoa tse ka mamellang maemo ana a thata. Mohlala, re sebelisa lisebelisoa tse hanyetsanang le radiation - mme re etsa lithuto tsa taolo ea mocheso ho netefatsa hore li-slip rings li ka sebetsa ka mokhoa o ts'epahalang sebakeng.

Bokamoso ba mehele ea carbon brush puisanong ea sathelaete bo shebahala bo ts'episa. Ha tlhoko ea litsamaiso tse tsoetseng pele tsa puisano tsa satellite e ntse e eketseha, litlhoko tsa mehele ea carbon brush le tsona li tla ba thata le ho feta. Re lula re etsa lipatlisiso le ho nts'etsapele mahlale a macha ho ntlafatsa ts'ebetso ea liring tsa rona tsa "carbon brush slip".

Mohlala, re ntse re lekola ts'ebeliso ea li-nanomaterials ho matlafatsa tsamaiso ea motlakase le ho sesa ha brashi ea khabone le selikalikoe se thellang. Re ntse re sebeletsa ho etsa li-slip ringring tse bohlale tse ka - hlokomela tšebetso ea tsona le ho lemoha mathata afe kapa afe a ka bang teng ka nako - ea sebele.

Qetellong, mehele ea carbon brush slip ke karolo ea bohlokoa mekhoeng ea puisano ea sathelaete. Ba bapala karolo ea bohlokoa phetisong ea matla, mats'oao le phetiso ea data, le ho netefatsa ts'ebetso e tšepahalang ea satellite. Joalo ka morekisi oa li-ring ring ring, re ikemiselitse ho fana ka - lihlahisoa tsa boleng bo holimo tse fihlelang litlhoko tse ikhethileng tsa indasteri ea likhokahano ea sathelaete.

Haeba u le 'marakeng bakeng sa mehele ea carbon brush bakeng sa tsamaiso ea hau ea sathelaete ea puisano, re u mema hore u ikopanye le rona bakeng sa lipuisano tse qaqileng. Sehlopha sa rona sa litsebi se ikemiselitse ho u thusa ho khetha sehlahisoa se loketseng ka ho fetisisa le ho fana ka tšehetso ea tekheniki. Ha re sebetseng 'moho ho netefatsa katleho ea merero ea hau ea puisano ea sathelaete.
