Batho ba bangata ba tseba hore mekhahlelo e 'meli ea compressor e loketse tlhahiso ea khatello e phahameng,' me mohato oa pele o loketse tlhahiso e kholo ea khase.Ka linako tse ling ho hlokahala ho etsa li-compress tse fetang tse peli.Ke hobane'ng ha u hloka compression graded?
Ha khatello ea ts'ebetso ea khase e hlokahala hore e be e phahameng, tšebeliso ea khatello ea mohato o le mong ha e na chelete feela, empa ka linako tse ling e bile e ke ke ea khoneha, 'me khatello ea mekhahlelo e mengata e tlameha ho sebelisoa.Multi-stage compression ke ho qala khase ho tloha ho inhalation, 'me ka mor'a ho matlafatsa' maloa ho fihlela khatello e hlokahalang ea ho sebetsa.
1. Boloka tšebeliso ea matla
Ka compression ea mekhahlelo e mengata, pholileng e ka hlophisoa pakeng tsa mekhahlelo, e le hore khase e hatelitsoeng e be tlas'a pholiso ea isobaric ka mor'a ho hatella mohato o le mong ho fokotsa mocheso, ebe o kena sethaleng se latelang sa cylinder.Mocheso o theoleloa 'me boima bo eketseha, e le hore ho be bonolo ho hatella ka ho eketsehileng, e ka bolokang matla a matla haholo ha a bapisoa le khatello ea nako e le' ngoe.Ka hona, tlas'a khatello e ts'oanang, sebaka sa mosebetsi sa khatello ea mekhahlelo e mengata se tlase ho feta sa khatello ea mohato o le mong.Ha palo ea mekhahlelo e ntse e eketseha, ho sebelisoa matla a mangata le ho atamela haufi le khatello ea isothermal.
Tlhokomeliso: Compressor ea moea ea compressor ea screw air e kentsoeng ka oli e haufi haholo le ts'ebetso e sa fetoheng ea mocheso.Haeba u tsoela pele ho hatella 'me u tsoela pele ho pholile ka mor'a hore u fihle sebakeng sa saturated, metsi a condensed a tla theoha.Haeba metsi a koalehileng a kena ka karohanong ea moea oa oli (tanka ea oli) hammoho le moea o hatelitsoeng, o tla etsa hore oli e pholileng e be emulsify le ho ama phello ea lubrication.Ka ho eketseha ho tsoelang pele ha metsi a pholileng, boemo ba oli bo tla tsoela pele ho phahama, 'me qetellong oli e pholileng e tla kena tsamaisong hammoho le moea o hatelitsoeng, o silafatsa moea o hatelitsoeng le ho baka liphello tse tebileng tsamaisong.
Ka hona, e le ho thibela ho hlahisoa ha metsi a khutsitseng, mocheso ka kamoreng ea khatello e ke ke ea e-ba tlaase haholo 'me e tlameha ho ba holimo ho feta mocheso oa condensation.Mohlala, konpresser ea moea e nang le khatello ea ho tsoa ho 11 bar (A) e na le mocheso o tlase oa 68 °C.Ha mocheso ka kamoreng ea ho hatella o le ka tlase ho 68 ° C, metsi a condensed a tla theoha.Ka hona, mocheso oa mocheso oa "screw air compressor" o kentsoeng ka oli o ke ke oa ba tlase haholo, ke hore, ts'ebeliso ea compression ea isothermal ka "screw air compressor" e kentsoeng ka oli e fokotsehile ka lebaka la bothata ba metsi a khutsitseng.
2. Ntlafatsa tšebeliso ea molumo
Ka lebaka la mabaka a mararo a ho etsa, ho kenya le ho sebetsa, molumo oa tumello ka silinda e lula e ke ke ea qojoa, 'me molumo oa tumello ha o fokotse ka ho toba feela molumo o sebetsang oa silinda, empa hape le khase e setseng ea khatello e phahameng e tlameha ho atolosoa ho fihlela khatello ea ho hula. , moqomo o ka qala ho hema khase e ncha, e leng ho lekanang le ho tsoela pele ho fokotsa molumo o sebetsang oa cylinder.
Ha ho thata ho utloisisa hore haeba tekanyo ea khatello e kholoanyane, khase e setseng ka molumo oa tumello e tla atoloha ka potlako, 'me molumo o sebetsang oa silinda e tla ba o monyenyane.Maemong a feteletseng, esita le ka mor'a hore khase ea molumo oa tumello e atolosoe ka ho feletseng ka silindara, khatello e ntse e sa fokotsehe ho feta khatello ea ho hula.Ka nako ena, ho hula le ho qeta ho ke ke ha tsoela pele, 'me molumo o sebetsang oa silinda e fetoha zero.Haeba compression ea mekhahlelo e mengata e sebelisoa, tekanyo ea khatello ea mohato ka mong e nyane haholo, 'me khase e setseng ka har'a molumo oa tumello e atoloha hanyenyane ho fihlela khatello ea ho hula, eo ka tlhaho e eketsang molumo o sebetsang oa cylinder, ka tsela eo e ntlafatsa sekhahla sa tšebeliso ea. molumo oa cylinder.
3. Fokotsa mocheso oa ho tsoa
Thempereichara ea khase ea ho tima ea compressor e eketseha ka keketseho ea tekanyo ea khatello.Ha tekanyo ea khatello e phahame, mocheso oa khase ea ho tsoa o phahame, empa mocheso o feteletseng oa khase ea ho tsoa hangata ha o lumelloe.Lebaka ke hobane: ka har'a compressor e tlotsitsoeng ka oli, mocheso oa oli e tlotsang o tla fokotsa viscosity mme o mpefatse ho roala.Ha mocheso o phahama haholo, ho bonolo ho etsa li-deposit tsa carbon ka har'a silinda le holim'a valve, ho mpefatsa ho senyeha, esita le ho phatloha.Ka mabaka a sa tšoaneng, mocheso oa mocheso o fokotsehile haholo, kahoo khatello ea mekhahlelo e mengata e tlameha ho sebelisoa ho fokotsa mocheso oa ho qeta.
Tlhokomeliso: Khatello e hlophisitsoeng e ka fokotsa mocheso oa mocheso oa screw air compressor, 'me ka nako e ts'oanang, e ka boela ea etsa hore mokhoa oa mocheso oa compressor oa moea o be haufi le khatello ea mocheso e sa khaotseng kamoo ho ka khonehang ho finyella phello ea ho boloka matla, empa ha se e phethahetseng.Haholo-holo bakeng sa li-screw air compressors tse kentsoeng ka oli tse nang le khatello ea ho tima ea 13 bar kapa ka tlase, ka lebaka la oli e pholileng ea mocheso o tlase e kentsoeng nakong ea ts'ebetso ea khatello, mokhoa oa ho hatella o se o ntse o le haufi le mocheso o sa feleng, 'me ha ho hlokahale khatello ea bobeli.Haeba khatello e entsoeng ka sethala e etsoa motheong oa ho pholisa ente ea oli, sebopeho se rarahane, litšenyehelo tsa tlhahiso lia eketseha, 'me ho hanyetsa phallo ea khase le tšebeliso ea matla a eketsehileng le tsona lia eketseha, e leng tahlehelo e fokolang. .Ho phaella moo, haeba mocheso o le tlase haholo, ho thehoa ha metsi a khutsitseng nakong ea ts'ebetso ea khatello ho tla lebisa ho senyeha ha boemo ba tsamaiso, ho fella ka liphello tse tebileng.
4. Fokotsa matla a khase a sebetsang holim'a molamu oa piston
Ho piston compressor, ha tekanyo ea compression e phahame 'me khatello ea mohato o le mong e sebelisoa, bophara ba silinda e kholoanyane, 'me khatello e phahameng ea khase ea ho qetela e sebetsa sebakeng se seholo sa piston,' me khase e piston e kholoanyane.Haeba khatello ea mekhahlelo e mengata e amoheloa, matla a khase a sebetsang ka piston a ka fokotsoa haholo, kahoo ho ka khoneha ho etsa hore mochine o be bobebe le ho ntlafatsa katleho ea mochine.
Ehlile, compression ea mekhahlelo e mengata ha e betere ho feta.Hobane ha palo ea mekhahlelo e ntse e eketseha, mohaho oa compressor o rarahane haholoanyane, ho eketseha ha boholo, boima le litšenyehelo;ho eketseha ha phallo ea khase, ho eketseha ha tahlehelo ea khatello ea valve ea khase le tsamaiso, joalo-joalo, ka linako tse ling ha palo ea mekhahlelo e ntse e eketseha, moruo o tlaase, ho feta palo ea mekhahlelo.Ka likarolo tse ling tse tsamaeang, monyetla oa ho hlōleha o tla boela o eketsehe.Bokhoni ba mechine le bona bo tla fokotseha ka lebaka la khohlano e ntseng e eketseha.
