Iyo pneumatic system yemotokari nematarakita inoshanda zvakajairwa mune imwe dzvinyiriro renji, kana kudzvinyirira kuchichinja, kutadza kwayo uye kuparara kunogoneka.Kusagadzikana kwekumanikidzwa muhurongwa kunopiwa nemutongi - verenga nezvechikwata ichi, mhando dzayo, chimiro, kushanda, pamwe nekugadzirisa uye kugadzirisa munyaya yacho.
Chii chinonzi pressure regulator?
Pressure regulator chikamu cheiyo pneumatic system yemotokari uye akasiyana midziyo;Chishandiso chinovimbisa kusimba kwemhepo yekumanikidza muhurongwa, uye inoita akati wandei ekudzivirira uye ekudzivirira mabasa.
Ichi chikwata chinogadzirisa mabasa anotevera:
• Kuchengetedza mhepo yemhepo muhurongwa mune imwe nguva yakatarwa (650-800 kPa, zvichienderana nemhando yemidziyo);
• Kudzivirirwa kwepneumatic system kubva pakudzvinyirira kuwedzera pamusoro pemuganhu wakagadzwa (pamusoro pe1000-1350 kPa, zvichienderana nemhando yezvigadzirwa);
• Kudzivirira uye kudzivirira kwegadziriro kubva pakusvibiswa uye kuora nekuda kwekubuda kweperiodic ye condensate mumhepo.
Basa guru remutongi nderokuchengetedza mhepo yemhepo muhurongwa mukati mehutano hwakasimbiswa hwekushanda, pasinei nemitoro yemazuva ano, nhamba yevatengi vanobatana, mamiriro ekunze emamiriro ekunze, nezvimwewo. condensate yakaunganidzwa muzvikamu zvehurongwa (kunyanya mune yakakosha condensing inogamuchira) inobviswa mumhepo, inovadzivirira kubva mukuora, kutonhora uye kusvibiswa.
Chigadzirwa uye musimboti wekushanda kweiyo pressure regulator
Kune akawanda marudzi uye mamodheru ekumanikidza kudzora pamusika nhasi, asi ese anowira mumapoka maviri makuru:
• Standard regulators;
• Regulators akasanganiswa ne adsorber.
Zvishandiso zvemhando yekutanga zvinogadzirisa kudzvanywa muhurongwa uye kuita mabasa ekudzivirira, nepo dehumidification yemhepo inoitwa nechikamu chakasiyana - unyoro uye separator yemafuta (kana yakaparadzana mafuta separator uye air dryer).Zvishandiso zverudzi rwechipiri zvakashongedzerwa ne adsorber cartridge, iyo inopa yakawedzera mhepo dehumidification, ichipa kuchengetedzwa kuri nani kune pneumatic system.
Vese vanodzora vane mudziyo wakafanana, chimwe nechimwe chazvo chinopa akati wandei zvinhu zvakakosha:
Pressure regulator dhizaini
• Kupinza uye kupera mavharuvhu pane imwechete stem;
• Ivhavha isina kudzoka (iri padivi pepombi yekubuda, inodzivirira kudonha kwekumanikidza muhurongwa kana compressor ichidzimwa);
• Kubuda kwevhavha (iri padivi rezasi remhepo, inopa kubuda kwemhepo mumhepo);
• Kuenzanisa piston yakabatanidzwa kune mavharuvhu ekutora uye ekupera (inopa kuvhura / kuvhara kwekutora uye mavharuvhu ekupedza, inogadzirisazve mhepo inoyerera mukati memutongi).
Zvese zvikamu uye zvikamu zveyuniti zviri mune simbi kesi ine system yemachaneli uye cavities.Iyo regulator ine maburi mana (pombi) yekubatanidza kune pneumatic system yemotokari: inlet - yakamanikidzwa mhepo kubva kune compressor inopinda mairi, inobuda - kuburikidza nayo mhepo kubva kune regulator inopinda muhurongwa, mhepo - yakamanikidzwa mhepo uye condensate inoburitswa mukati. mhepo kuburikidza naro, uye yakakosha yekuputira matayi.Iyo yekubuda mumhepo inogona kuve yakashongedzerwa nemuffler - mudziyo wekudzikisa kusimba kweruzha rwunobva mukudzikiswa kwekumanikidza.Iyo tire inflation outlet inogadzirwa nenzira yekubatanidza hose, yakavharwa nevhavha yekudzivirira.Zvakare, iyo regulator inopa imwe yemhepo kubuda kwediki muchinjiko-chikamu, inodiwa kune yakajairwa mashandiro eiyo discharge piston, mapaipi haana kubatana kune ino terminal.
Mune zvigadziriso zvine adsorber, mudziyo uzere ne hygroscopic zvinhu unosungirirwa paimba, uchitora hunyoro kubva kumhepo inobva kune compressor.Kazhinji, adsorber inogadzirwa nenzira yekaturiji yakajairwa ine gomo rakarukwa, iro rinogona kutsiviwa kana zvichidikanwa.
Kushanda kweiyo pressure regulator hakuna kunyanya kuoma.Kana injini inotanga, mhepo yakamanikidzwa kubva kune compressor inopinda iyo inoenderana terminal ye regulator.Chero bedzi kudzvinyirirwa kuri munharaunda yekushanda kana zvishoma, mavharuvhu ari munzvimbo iyo mhepo inoyerera yakasununguka kuburikidza nemutongi muhurongwa, inozadza vanogamuchira uye inovimbisa kushanda kwevatengi (kupedza uye cheki mavharuvhu akazaruka, the mavharuvhu ekupinda nekuburitsa akavharwa).Kana dzvinyiriro ichisvika pamuganho wepamusoro wechikamu chekushanda (750-800 kPa), mavharuvhu ekuburutsa uye ekupinza anovhurika, uye cheki uye mavharuvhu ekupera anovhara, semhedzisiro, nzira yemhepo inoshanduka - inopinda mumhepo yekubuda uye inoburitswa. .Saka, iyo compressor inotanga kusashanda, kuwedzera kwekumanikidzwa muhurongwa kunomira.Asi pakarepo kana kudzvinyirirwa muhurongwa kunodonha kusvika kumucheto wakaderera wehuwandu hwekushanda (620-650 kPa), mavharuvhu anoenda kunzvimbo iyo mhepo kubva kune compressor inotanga kuyerera ichidzokera muhurongwa.
Muchiitiko icho mutongi anodzima compressor kana kumanikidza kunosvika 750-800 kPa, ipapo mune ramangwana nzira yekuchengetedza ichashanda, iyo basa rinoitwa neiyo imwechete yekuburitsa valve.Uye kana dzvinyiriro inosvika 1000-1350 kPa, ipapo kuvhara kwevhavha inovhura, asi zvikamu zvakasara zvechikwata hazvichinje nzvimbo yavo - somugumisiro, hurongwa hwakabatana nemhepo, kusunungurwa kwekukurumidzira kunoitika.Kana kudzvinyirirwa kunodonha, vharuvhu yekuburitsa inovhara uye sisitimu inoramba ichishanda zvakajairika.
Kudzvinyirira uko compressor inobviswa kubva kupneumatic system inogadziriswa nechisimba chechitubu chekuenzanisa piston.Inogona kuchinjwa kuburikidza nekugadzirisa screw yakazorora paplate yechirimo.Iyo screw inogadziriswa ne locknut, iyo inodzivirira iyo mechanic kubva pakufa nekuda kwekudedera, kuvhunduka, jolts, nezvimwe.
Maregulator ane adsorber anoshanda zvakafanana, asi anopa maviri ekuwedzera mabasa.Kutanga, kana kudzvinyirirwa kwasunungurwa, mhepo haingosunungurwi mumhepo - inopfuura nepakati adsorber kune imwe nzira, ichibvisa unyoro hwakaunganidzwa kubva mairi.Uye, chechipiri, kana iyo adsorber yakavharwa (mhepo kubva kune compressor inosefa, asi pane nguva dzose kune imwe huwandu hwehutsvina mairi, iyo inoiswa pane adsorbent particles), iyo bypass valve inotangwa, uye mhepo kubva discharge line inopinda zvakananga muhurongwa.Muchiitiko ichi, mhepo haina dehumidified, uye adsorber inofanira kutsiviwa.
A pressure regulator yemhando ipi neipi yakaiswa mumutsara wekuburitsa wepneumatic system pakarepo kuseri kwe compressor uye mafuta uye unyoro separator (kana ichipihwa muhurongwa).Mhepo kubva kune regulator, zvichienderana nedunhu reiyo pneumatic system, inogona kupihwa kune yechando fuse uyezve kuvhavhavhavhavha yekuchengetedza, kana kutanga kune inotsikisa inogamuchira uyezve kune yekuchengetedza vharafu.Nenzira iyi, mutongi anotarisisa kudzvanywa muhurongwa hwese uye anoidzivirira kubva pakuremerwa.
Dhiagiramu yepressure regulator ine adsorber
Nyaya dzekusarudza uye kugadziriswa kwezvinodzora zvinodzvinyirira
Panguva yekushanda, mutongi wekumanikidzika anoratidzwa nekusvibiswa uye mitoro yakakomba, izvo zvishoma nezvishoma zvinotungamirira pakuderera kwekushanda kwayo uye kuputsika.Kuwedzerwa kwehupenyu hwebasa remutongi kunowanikwa nekuongorora kwayo uye kuchenesa panguva yekugadzirisa kwemwaka wemotokari.Kunyanya, zvinodikanwa kuchenesa ma strainers akavakirwa muvatongi uye kutarisa iyo unit yese yekudonha.Mune maregulators ane adsorber, zvinodikanwa zvakare kutsiva cartridge neiyo adsorbent.
Muchiitiko chekushaya simba kwemutongi - kudonha, kushanda kusina kunaka (kutadza kudzima compressor, kunonoka mumhepo inobuda, nezvimwewo) - chikwata chinofanira kugadziriswa kana kuchinjwa musangano.Muchiitiko chekutsiva, iwe unofanirwa kusarudza regulator yemhando imwechete uye modhi yakaiswa pamotokari (kana analogue yayo inoenderana nehunhu hwepneumatic system).Mushure mekuiswa, mudziyo mutsva unofanirwa kugadziridzwa zvinoenderana nekurudziro yemugadziri wemotokari.Nechisarudzo chakanaka uye kutsiva kwemutongi, iyo pneumatic system ichashanda yakavimbika mumamiriro akasiyana-siyana.
