Iindaba

(1), uxinzelelo: uxinzelelo ekubhekiselwa kulo kwishishini lecompressor libhekisa kuxinzelelo (P)

Ⅰ, uxinzelelo lwe-atmospheric eqhelekileyo (ATM)

Ⅱ, uxinzelelo lokusebenza, ukufunxa, uxinzelelo lokukhupha, kubhekiselele kwi-compressor suction yomoya, uxinzelelo lokukhupha

① Uxinzelelo olulinganiswe ngoxinzelelo lwe-atmospheric njengoko indawo ye-zero ibizwa ngokuba nguxinzelelo lomphezulu P(G).

② Uxinzelelo kunye ne-vacuum epheleleyo njengoko indawo ye-zero ibizwa ngokuba yi-absolute pressure P (A).

Uxinzelelo lokukhupha oludla ngokunikezelwa kwicompressor nameplate luxinzelelo lwegeyiji.

Ⅲ, uxinzelelo olwahlukileyo, umahluko woxinzelelo

Ⅳ, ilahleko yoxinzelelo: ukulahleka koxinzelelo

Ⅴ, icompressor yomoya, ukuguqulwa kweyunithi yoxinzelelo eqhelekileyo:

1MPa (MPa) =106Pa (PASCAL)

Ibha (ibha) =0.1MPa

I-1atm (uxinzelelo oluqhelekileyo lwe-atmospheric) =1.013bar=0.1013MPa

Ngokuqhelekileyo kwishishini le-compressor yomoya, "kg" ibhekisela kwi "bar".

(2), ukuhamba okuqhelekileyo: ukuhamba okuqhelekileyo e-China kwaziwa ngokuba kukufuduswa okanye ukuhamba kwegama.

Ngokuqhelekileyo, phantsi koxinzelelo olufunekayo lokukhupha, umthamo wegesi okhutshwe yi-compressor yomoya ngexesha leyunithi liguqulelwa kwisimo sokuthatha, okuyixabiso lomthamo woxinzelelo lokufunxa kunye nobushushu bokufunxa kunye nomswakama kwinqanaba lokuqala lombhobho wokungena.Ixesha leyunithi libhekisa kumzuzu omnye.

Oko kukuthi, umthamo wokufunxa Q= CM *λ*D3*N=L/D*D3N

L: Ubude be-rotor

D: Ububanzi be-rotor

N: Isantya se-shaft ye-rotor

I-CM: I-Coefficient yomgca weprofayili

Lambda: ubude ukuya kwidayamitha ratio

Ngokomgangatho wesizwe, owona mthamo wokukhupha wecompressor womoya ngu ± 5% wokuhamba okuqhelekileyo.

Ilizwe loreferensi: umgangatho woxinzelelo lomoya, ubushushu obungama-20℃, ukufuma ngu-0℃, eli lizwe lireferensi eUnited States, eBritani, eOstreliya nakwamanye amazwe antetho isisiNgesi T =15℃.IYurophu neJapan T =0℃.

Imeko esemgangathweni: i-atmosfera enye eqhelekileyo, iqondo lobushushu 0℃, ukufuma 0

Ukuba iguqulelwe kwimeko yesiseko, iyunithi yi:m3/min (cubic ngomzuzu)

Ukuba iguqulelwe kwimeko eqhelekileyo, iyunithi ithi: Nm3/min (square esiqhelekileyo ngomzuzu)

Emva kwe-1 m / min = 1000 l / min

1 nm emva/umzuzu emva = 1.07 m/min

(3) Isiqulatho se-oyile yerhasi:

Ⅰ, ngeyunithi umthamo womoya ocinezelweyo kwioyile (kubandakanya ioyile, amasuntswana amisiweyo kunye nomphunga weoyile), umgangatho woguqulo ukuya kuxinzelelo lwe-0.1 MPa, iqondo lobushushu yi-20 ℃ kunye nokufuma okuhambelana ne-65% yexabiso lomgangatho. iimeko zomoya.Iyunithi :mg/m3 (ibhekisa kwixabiso lesibini elipheleleyo)

Ⅱ, uPPM uthe umkhondo wezinto kumxube weesimboli, ubhekisa kwinani kwisigidi esinye samakhulu ezigidi (ubunzima kunePPMw kunye nomthamo kunePPMv).(ebhekisa kumlinganiselo)

Ngokuqhelekileyo sibhekisela kwiPPM njengomlinganiselo wobunzima.(Isigidi esinye sekhilogram yimiligram)

1PPMW =1.2mg/m3(Pa =0.1MPa, t=20℃, φ=65%)

(4) Amandla athile: abhekisa kumandla asetyenziswe ngumthamo othile wokuhamba kwecompressor.Luhlobo lwesalathiso sokuvavanya ukusebenza kwecompressor phantsi koxinzelelo olufanayo lwegesi kunye noxinzelelo olufanayo lokukhupha.

Amandla athile = amandla e-shaft (amandla ewonke afakwayo)/ i-exhaust (kW/m3·min-1)

Amandla e-Shaft: Amandla afunekayo ukuqhuba i-shaft ye-compressor.

i-P axis =√3×U×I× COS φ(9.5)×η(98%) imoto ×η drive

(5), umbane kunye namanye amagama

Ⅰ, amandla: okwangoku ngeyunithi yexesha lokwenza umsebenzi (P), iyunithi nguW (watt

Sidla ngokusebenzisa i-kW (kilowatt), kodwa namandla ehashe (HP)

1 KW HP1HP = 1.34102 = 0.7357 KW

Ⅱ, okwangoku: i-elektroniki phantsi kwesenzo samandla ombane, kukho imigaqo yokuhamba kwicala elinye

Xa ishukuma, yenza u-A wangoku kwi-A amperes.

Ⅲ, amandla ombane: ngenxa yokuba intloko kunye nokuhamba kwamanzi, kukho umahluko onokubakho,

Ibizwa ngokuba yi-voltage (U), kwaye iyunithi yi-V (volts).

Ⅳ, isigaba, sibhekisa kucingo, isigaba sesithathu socingo: sibhekisa kumsonto wesigaba esithathu (okanye ucingo)

Umgca osembindini (okanye umgca onguziro), isigaba esinye sibhekisa kumgca wesigaba (okanye umgca womlilo)

Umgca osembindini weengcambu (okanye umgca onguziro)

Ⅴ, i-frequency: i-alternating current (ac) ukugqiba amandla e-electromotive ye-electromotive force ye-electromotive force ye-electromotive cycle yenguqu echanekileyo kunye nembi, inani lesibini, sebenzisa (f), ngokweyunithi-Hertz (Hz) ye-50 Hz etshintshana ngokuphindaphindiweyo kwilizwe lethu, phesheya. uya 60Hz.

I-Ⅵ, i-frequency: tshintsha i-frequency, kwisicelo secompressor yomoya, ngokuguqula ukuphindaphinda kwamandla okutshintsha isantya semoto, ukuze kufezekiswe injongo yohlengahlengiso lokuhamba.Isantya sokuhamba sinokuhlengahlengiswa kwi-0.1bar ngokuguqulwa kwamaxesha amaninzi, okunciphisa kakhulu umsebenzi ongasebenziyo kwaye ufezekise injongo yokonga amandla.

Ⅶ, umlawuli: kukho iindidi ezimbini eziphambili zomlawuli kwishishini: uhlobo lwesixhobo kunye ne-PL

Inkqubo, sisebenzisa isilawuli se-PLC, luhlobo lwe

Umlawuli ocwangcisekileyo oqulunqwe yi-microcomputer ye-chip enye kunye namanye amacandelo.

Ⅷ, iligi ethe tye: uqhagamshelo oluthe ngqo, kwishishini lecompressor yomoya libhekisa ekubopheni ngokudibanisa

Ⅸ, ukulayisha / ukukhulula, imo yokusebenza yecompressor yomoya, ngokubanzi ibhekisa kwicompressor yomoya.

Inkqubo epheleleyo yokufunxa kunye nokukhupha ikwimeko yokulayisha, ngaphandle koko ikwimeko yokukhulula

Ⅹ, umoya/amanzi: ibhekisa kwindlela yokupholisa

Ⅺ, ingxolo: iyunithi: dB (A) (+ 3) (dB) iyunithi yomgangatho woxinzelelo lwesandi

Ⅻ, ibakala lokhuseleko: kuthiwa isixhobo sombane esingangeni luthuli, sithintela umzimba wasemzini, singangeni manzi, njl.

Ixabiso leqondo lokungangeni moya libonakaliswa yi IPXX

Ⅷ, imowudi yokuqalisa: isiqalo esithe ngqo, siqhele ukuqala ngendlela yokuguqula unxantathu.

(6) Iqondo lobushushu lendawo yombethe ℃

Umoya omanzi phantsi koxinzelelo olunjalo lokupholisa, yenza ekuqaleni iqulethe umphunga wamanzi angaxutywanga emoyeni iba ngubushushu obugcweleyo bomphunga, ngamanye amazwi, xa uncitshiswe kwiqondo lobushushu elithile, iqondo lobushushu lomoya emoyeni iqulethe umphunga wamanzi ongaxutywanga ukufikelela kwimo yokuhluza ( Oko kukuthi umphunga uqala ukunyibilika, ulwelo luyajika luphume), iqondo lobushushu liqondo lombethe lerhasi.

Iqondo lombethe loxinzelelo: libhekisa kwirhasi enoxinzelelo oluthile olupholileyo kwiqondo lobushushu elithile, umphunga wamanzi angaxutywanga oqulethwe kuwo uba ngumphunga wamanzi, iqondo lobushushu liqondo lombethe wegesi.

Indawo yombethe we-atmospheric: kuxinzelelo oluqhelekileyo lwe-atmospheric, igesi iyaphola ukuze imixholo yayo ingagcwali.

Umphunga wamanzi uba ngumphunga wamanzi ophuphumayo ukuya kwiqondo lobushushu

Kwishishini le-compressor yomoya, indawo yombethe yinqanaba lokoma kwerhasi
