Siyini isizathu se-jitter ye-valve yokuthatha i-compressor yomoya?

I-valve yokungena iyingxenye ebalulekile yesistimu ye-screw air compressor. Kodwa-ke, lapho i-valve yokudonsa isetshenziswa kumshini womoya ozibuthe oguquguqukayo oguquguqukayo, kungase kube nokudlidliza kwevalvu yokudonsa. Uma injini isebenza ngefrikhwensi ephansi kakhulu, ipuleti lokuhlola lizodlidliza, okuholela kumsindo wokungenisa. Ngakho-ke, siyini isizathu sokudlidliza kwevalvu yokuthatha ye-compressor yomoya ozibuthe eguquguqukayo unomphela?

Izizathu zokudlidliza kwe-valve yokuthatha ye-compressor yomoya eguquguqukayo kazibuthe unomphela:

Isizathu esiyinhloko salesi senzakalo isiphethu esingaphansi kwepuleti ye-valve ye-valve yokungena. Uma umthamo womoya owuthathayo ulincane, ukugeleza komoya akuzinzile futhi amandla entwasahlobo makhulu uma kuqhathaniswa, okuzokwenza ukuthi ipuleti le-valve lidlidlize. Ngemva kokufaka esikhundleni sentwasahlobo, amandla entwasahlobo mancane, angaxazulula izinkinga ezingenhla ngokuyisisekelo.

Eqinisweni, lapho i-valve yokungena icushiwe, i-valve yokungena ye-compressor yomoya ivaliwe, futhi injini ishayela injini enkulu ukuba ingenzi lutho. Lapho i-valve ilayishiwe, i-valve yokungena iyavuleka. Ngokuvamile, ipayipi legesi elikhulu kuno-5mm likhishwa esimbozweni esiphezulu sesihlukanisi segesi kawoyela, futhi i-valve yokungena ilawulwa ngokushintsha kwe-valve ye-solenoid (imvamisa i-solenoid valve ivuliwe). Lapho i-valve ye-solenoid inikwa amandla, i-valve yokungena ngaphandle komoya ocindezelwe idonswa ngokuzenzakalelayo futhi ivuleke, i-valve yokungena iyalayishwa, futhi i-compressor yomoya iqala ukufutheka. Lapho i-valve ye-solenoid ikhishwa amandla, umoya ocindezelwe ungena ku-valve yokudonsa, umfutho womoya uphakamisa ipiston, i-valve yokudonsa iyavala, futhi i-valve yokukhipha umoya iyavuleka.

Umfutho womoya uhlukaniswe ngezindlela ezimbili, enye ingene kuvalvu yokukhipha umoya futhi enye ingene ku-compressor. I-valve yokukhipha i-exhaust ine-fitting yokulungisa usayizi we-exhaust ukuze ulawule ukucindezela emgqonyeni wesihlukanisi. Ingcindezi ngokuvamile ingalungiswa ibe ngu-3 kg, ingcindezi iyanda ngokujika iwashi, futhi ingcindezi iyancipha ngokuphikisana newashi, futhi nati elilungisiwe lilungisiwe.

Ilayisha indlela yokulungisa ivolumu yomoya we-valve, lapho ukusetshenziswa kwegesi yemvelo yomsebenzisi kungaphansi kwevolumu yokukhipha elinganiselwe yeyunithi, ingcindezi ohlelweni lwenethiwekhi yamapayipi omsebenzisi izokhuphuka. Lapho ingcindezi ifinyelela inani elibekiwe lokucindezela kokuthulula, i-valve ye-solenoid ivaliwe, umthombo womoya unqanyuliwe, futhi ukulawulwa kungena ku-valve ehlanganisiwe yesilawuli sokungenisa. I-piston ivala ngaphansi kwamandla entwasahlobo futhi i-valve yokukhipha iyavuleka. Umoya ocindezelwe kusihlukanisi segesi kawoyela ubuyela endaweni yokungena komoya, futhi umfutho wehlela enanini elithile.

Ngalesi sikhathi, i-valve encane yokucindezela ivaliwe, inethiwekhi yepayipi yomsebenzisi ihlukaniswa neyunithi, futhi iyunithi isesimweni sokusebenza okungenamthwalo. Njengoba ingcindezi yenethiwekhi yepayipi yomsebenzisi yehla kancane kancane enanini elimisiwe lokucindezela komthwalo, i-valve ye-solenoid ithola amandla futhi ixhunywe kumthombo womoya wokulawula we-valve ehlanganisiwe kusilawuli sokuthatha. Ngaphansi kwesenzo salokhu kucindezela, i-piston ivula ngokumelene namandla entwasahlobo, ngesikhathi esifanayo i-valve yokukhipha ivala, futhi iyunithi iqala kabusha ukusebenza kokulayisha.

Lokhu okungenhla kuyisizathu sokudlidliza kwevalvu yokuthatha ye-compressor yomoya eguquguqukayo kazibuthe unomphela. I-valve yokungenisa isebenza ngokuhlanganyela ne-solenoid valve, inzwa yokucindezela, nesilawuli se-microcomputer ukulawula ukushintshwa kwembobo yokufaka i-compressor. Lapho iyunithi iqala, I-valve yokungena ivaliwe, edlala indima yokulungiswa kwe-throttling yokungenisa umoya, ukuze i-compressor iqale ekulayisheni okulula; lapho i-compressor yomoya isebenza ngomthwalo ogcwele, i-valve yokungena ivuliwe ngokugcwele; lapho i-compressor yomoya isebenza ngaphandle komthwalo, i-valve yokungena ivaliwe futhi i-oyili negesi ihlukaniswa Ukucindezela ku-separator kukhishwa ku-0.25-0.3MPa ukuze kuqinisekiswe ukucindezela kokunikezwa kwamafutha enjini eyinhloko; lapho umshini uvaliwe, i-valve yokungena ivaliwe ukuvimbela igesi ku-separator ye-oil-gas kusukela ekugelezeni emuva, okubangela ukuthi i-rotor ihlehlise futhi umjovo wamafutha echwebeni lokungena kwenzeke.
