Compressed air system, nenzira nhete, inoumbwa nemhepo sosi yemidziyo, mhepo yekunatsa midziyo uye mapaipi ane hukama.Mupfungwa yakafara, pneumatic axiliary components, pneumatic actuators, pneumatic control components, vacuum components, etc. zvese ndezvechikamu che compressed air system.Kazhinji, midziyo yemhepo compressor chiteshi ndeye yakamanikidzwa mhepo system mune nhete pfungwa.Iyi inotevera nhamba inoratidza yakajairika compressed air system inoyerera chati:
Iyo mhepo sosi yemidziyo (air compressor) inosveta mumhepo, inomanikidza mhepo iri munzvimbo yechisikigo kuita mhepo yakamanikidzwa nemhepo yakakwira, uye inobvisa hunyoro, mafuta uye humwe hutsvina mumhepo yakamanikidzwa kuburikidza nemidziyo yekuchenesa.
Mhepo mune zvakasikwa inoumbwa nemusanganiswa wemagasi akasiyana (O₂, N₂, CO₂ ... nezvimwewo), uye mhute yemvura ndeimwe yacho.Mhepo ine imwe mhute yemvura inonzi mhepo yakanyorova, uye mweya usina mhute wemvura unonzi mhepo yakaoma.Mhepo yakatitenderedza imhepo yakanyorova, saka svikiro rekushanda remhepo compressor imhepo yakanyorova.
Kunyange zvazvo hupfu hwemvura huri mumhepo ine hunyoro hushoma, huripo hune simba guru pane zvemuviri zvemweya wakanyorova.Mune yakamanikidzwa mweya yekuchenesa system, kuomeswa kwemhepo yakamanikidzwa ndechimwe chezvinhu zvikuru zviri mukati.
Pasi peimwe tembiricha uye kumanikidzwa mamiriro, zviri mukati memhute yemvura mumhepo ine hunyoro (kureva kuti, mvura mhute density) inogumira.Pane imwe tembiricha, kana huwandu hwemhute hwemvura hurimo hunosvika pahuwandu hunokwanisika, mweya wakanyorova panguva ino unonzi saturated air.Mhepo yakanyorova isina huwandu hunogona kuwanikwa hwemhute yemvura inonzi unsaturated air.
Panguva iyo mweya usina unsaturated ukava mweya wakazara, madonhwe emvura emvura anodzika mumhepo ine hunyoro, iyo inonzi "condensation".Condensation inowanzoitika.Semuenzaniso, hunyoro hwemhepo hwakakwirira muzhizha, uye zviri nyore kugadzira madonhwe emvura pamusoro pepombi yemvura.Mumangwanani echando, madonhwe emvura achaonekwa pamahwindo egirazi evagari.Zvose izvi zvinoumbwa nekutonhodzwa kwemhepo ine hunyoro pasi pekumanikidzika nguva dzose.Lu results.
Sezvambotaurwa pamusoro apa, tembiricha iyo mhepo isina unsaturated inosvika pakuzara inodaidzwa kuti dew point kana chikamu chemutsindo wemhute wemvura unoramba uripo (ndiko kuti, iyo yakazara mvura inochengetwa inochengetwa isingachinji).Kana tembiricha inodonha kusvika kune tembiricha yedova, pachava ne "condensation".
Dova remhepo ine hunyoro harisi chete rine chekuita nekupisa, asi zvakare rine chekuita nehuwandu hwehunyoro mumhepo ine hunyoro.Dova rinenge rakakwirira nekuwanda kwemvura, uye dova rakaderera nemvura shoma.
Iyo tembiricha yedova ine basa rakakosha mucompressor engineering.Semuenzaniso, kana tembiricha yekubuda kwemhepo compressor yakadzikira, musanganiswa wemafuta-gasi unodzika nekuda kwekudziya kwakadzika mugasi-gasi, izvo zvichaita kuti mafuta ekuzora ave nemvura uye anokanganisa maitiro ekuzora.naizvozvo.Iyo yekubuda tembiricha yemhepo compressor inofanirwa kugadzirwa kuti isadzike pane tembiricha yedova pasi pesimba rinoenderana.
Atmospheric dew point ndiyo tembiricha yedova iri pasi pemhepo yemhepo.Zvimwechetezvo, pressure dew point inoreva tembiricha yedova remhepo.
Hukama hunoenderana pakati penzvimbo yekumanikidza dova uye yakajairwa dzvinyiriro yedova point ine hukama nereshiyo yekumanikidza.Pasi penzvimbo imwechete yekumanikidza dova, iyo yakakura iyo compression reshiyo, inodzikisira inowirirana yakajairika dzvinyiriro yedova.
Mhepo yakamanikidzwa inobuda mumhepo compressor yakasviba.Izvo zvinosvibisa zvakanyanya ndezvi: mvura (madonhwe emvura yemvura, mhute yemvura uye gasious mvura mhute), mhute yakasara yekuzora mafuta (madonhwe emafuta mhute uye mhute yemafuta), tsvina yakasimba (marara emarara, simbi poda, faindi dzerabha, zvimedu zvetara uye sefa zvinhu, poda yakatsetseka yezvinhu zvekuisa chisimbiso, nezvimwewo), kusvibiswa kwemakemikari anokuvadza uye kumwe kusvibiswa.
Oiri yekuzora yakasakara inoshatisa rabha, mapurasitiki, uye zvekuvharisa, zvichikonzera kusashanda kwemavharuvhu uye zvigadzirwa zvinosvibisa.Hunyoro neguruva zvinokonzeresa kuti simbi nemapombi zviite ngura uye kuita ngura, zvichikonzera kuti zvikamu zvinofamba zvimire kana kusakara, zvichiita kuti zvinhu zvepneumatic zvisashande zvakanaka kana kubuda mweya.Hunyoro uye guruva zvinovharawo maburi ekudonha kana kusefa skrini.Mushure mechando chinoita kuti pombi iite chando kana kutsemuka.
Nekuda kwehurombo hwemhando yemhepo, kuvimbika uye hupenyu hwesevhisi yepneumatic system yakadzikira zvakanyanya, uye kurasikirwa kunokonzeresa kunowanzo kudarika zvakanyanya mutengo uye mutengo wekugadzirisa wemhepo sosi yekurapa mudziyo, saka zvinonyanya kudikanwa kusarudza nemazvo kurapwa kwemhepo sosi. system.
Ndeapi manyuko makuru ekunyorova mumhepo yakamanikidzwa?
Nzvimbo huru yekunyorova mumhepo yakamanikidzwa imhute yemvura inoyamwa nemhepo compressor pamwe nemhepo.Mushure mekunge mhepo ine hunyoro yapinda mumhepo compressor, huwandu hukuru hwehupfu hwemvura hunosvinwa mumvura ine mvura panguva yekumanikidza, izvo zvinozoderedza zvakanyanya hunyoro hwemhepo yakamanikidzwa pakubuda kwemhepo compressor.
Semuenzaniso, kana iyo system pressure iri 0.7MPa uye hunyoro hwemweya wakafemerwa huri 80%, kunyangwe iyo yakamanikidzwa mhepo inobuda kubva kumhepo compressor yakazara pasi pekumanikidzwa, kana ikashandurwa kune yemhepo yekumanikidza nyika isati yadzvanywa, hunyoro hwayo hunoenderana. chete 6 ~ 10%.Kureva kuti mwando wemweya wakatsikirirwa wakadzikiswa zvakanyanya.Nekudaro, sezvo tembiricha inodonha zvishoma nezvishoma mupombi yegasi nemidziyo yegasi, huwandu hukuru hwemvura yemvura hucharamba huchidzika mumhepo yakamanikidzwa.
Kusvibiswa kwemafuta mumhepo yakamanikidzwa kunokonzerwa sei?
Mafuta ekuzora emhepo compressor, mhute yeoiri uye madonhwe emafuta akarembera mumhepo yakadzika uye mafuta ekuzora ezvikamu zvepneumatic muhurongwa ndizvo zvinonyanya kukonzera kusvibiswa kwemafuta mumhepo yakamanikidzwa.
Kunze kwe centrifugal uye diaphragm air compressors, anenge ese emhepo compressor ari kushandiswa pari zvino (kusanganisira akasiyana oiri-asina lubricated air compressors) achave nemafuta akasviba akawanda kana mashoma (madonhwe emafuta, mhute yeoiri, mhute yemafuta uye kabhoni fission) mupombi yegasi.
Tembiricha yepamusoro yekamuri yekumanikidza yemhepo compressor ichaita kuti inenge 5% ~ 6% yemafuta inyunguduke, iparare uye iite oxidize, uye ichiiswa mukati memadziro emukati memhepo compressor pombi nenzira yekabhoni uye varnish firimu, uye chikamu chechiedza chichamiswa muchimiro chemhepo uye micro Chimiro chechinhu chinounzwa muhurongwa nemhepo yakamanikidzwa.
Muchidimbu, kune masisitimu asingade zvekuzora panguva yekushanda, mafuta ese uye zvinhu zvekuzora zvakasanganiswa mumhepo yakamanikidzwa inoshandiswa inogona kutorwa seyakasvibiswa nemafuta.Kune masisitimu anoda kuwedzera mafuta ekuzora panguva yebasa, ese anti-ngura pendi uye compressor mafuta ari mumhepo yakamanikidzwa anoonekwa semafuta kusvibiswa tsvina.
Ko tsvina yakasimba inopinda sei mumhepo yakamanikidzwa?
Nzvimbo huru dzetsvina dzakasimba mumhepo yakamanikidzwa ndeidzi:
①Mamiriro ekunze akatenderedza anosanganiswa nekusachena kwakasiyana kwehukuru hwakasiyana.Kunyangwe kana air compressor suction port ine mhepo sefa, kazhinji "aerosol" tsvina iri pasi pe5 μm inogona kuramba ichipinda mumhepo compressor nemhepo inofemerwa, yakasanganiswa nemafuta nemvura mupombi yekuburitsa panguva yekumanikidza.
②Kana iyo compressor yemhepo ichishanda, kupokana uye kudhumhana pakati pezvikamu zvakasiyana, kuchembera nekudonha kubva pazvisimbiso, uye carbonization uye fission yemafuta ekuzora patembiricha yepamusoro zvinokonzeresa zvidimbu zvakasimba sesimbi, guruva rerabha uye kabhoni. fission kuti iunzwe mupombi yegesi.
