(1), kudzvanywa: kudzvanywa kunotaurwa muindasitiri yecompressor kunoreva kudzvanywa (P)
Ⅰ, yakajairwa atmospheric pressure (ATM)
Ⅱ, kushanda nesimba, kusveta, kupera simba, zvinoreva kusveta kwemhepo compressor, kupera simba.
① Dzvinyiriro yakayerwa nemhepo yemuchadenga sezvo zero point inodaidzwa kuti surface pressure P(G).
② Kumanikidzwa neabsolute vacuum sezvo zero point inodaidzwa kuti absolute pressure P (A).
Iyo yekupopota yekumanikidza inowanzo kupihwa pacompressor nameplate ndiyo gauge pressure.
Ⅲ, kudzvinyirirwa kwakasiyana, kudzvanywa kwakasiyana
Ⅳ, kurasikirwa kwekumanikidzwa: kurasikirwa kwekumanikidza
Ⅴ, air compressor, iyo inowanzo shandiswa yekumanikidza unit shanduko:
1MPa (MPa) =106Pa (PASCAL)
1bar (bha) =0.1MPa
1atm (yakajairika atmospheric pressure) =1.013bar=0.1013MPa
Kazhinji mumhepo compressor industry, "kg" inoreva "bar".
(2), kuyerera kwezita: kuyerera kwezita muChina kunozivikanwawo sekutamisa kana kuyerera kwezita.
Kazhinji, pasi pesimba rinodiwa rekupedza simba, vhoriyamu yegesi inoburitswa nemhepo compressor panguva yeyuniti inochinjirwa kune inodya, inova iyo vhoriyamu kukosha kwekusveta uye tembiricha yekusveta uye humidity padanho rekutanga repombi yekupinza.Nguva yeyuniti inoreva miniti imwe.
Kureva kuti, vhoriyamu yekukweva Q= CM *λ*D3*N=L/D*D3N
L: Kureba kwe rotor
D: Diameter ye rotor
N: Iyo shaft kumhanya ye rotor
CM: Coefficient of profile line
Lambda: kureba kusvika kudhayamita reshiyo
Zvinoenderana nechiyero chenyika, iyo chaiyo yekuburitsa vhoriyamu yemhepo compressor ndeye ± 5% yezita rekuyerera.
Reference state: a standard atmospheric pressure, tembiricha 20 ℃, humidity is 0℃, iyi reference state iri kuUnited States, Britain, Australia nedzimwe nyika dzinotaura Chirungu T =15℃.Europe neJapan T =0℃.
Mamiriro ezvinhu: imwe yakajairika mhepo, tembiricha 0 ℃, humidity 0
Kana yashandurwa kuita base state, unit iri :m3/min (cubic paminiti)
Kana yashandurwa kuita standard state, unit iri:Nm3/min (standard square paminiti)
Mushure me1 m / min = 1000 l / min
1 nm mushure / maminetsi mushure = 1.07 m/min
(3) Oiri ine gasi:
Ⅰ, pachiyero cheyuniti yemhepo yakamanikidzwa muoiri (kusanganisira oiri, yakamiswa zvimedu uye mafuta mupfu), mhando yeshanduko kubva pakumanikidzwa kwe0.1 MPa, tembiricha i20 ℃ uye humidity ye65% kukosha kweiyo standard. mamiriro ekunze.Chiyero :mg/m3 (inoreva kukwana kwepeya yakakwana)
Ⅱ, PPM yakati inoteedzera zvinhu zviri mumusanganiswa wezviratidzo, zvinoreva nhamba mumiriyoni imwe neimwe mazana emamiriyoni (huremu kupfuura PPMw uye vhoriyamu kupfuura PPMv).(zvichireva chiyero)
Kazhinji tinonongedzera kuPPM sechiyero chehuremu.(Miriyoni imwe yekirogiramu imirigiramu)
1PPMW =1.2mg/m3(Pa =0.1MPa, t=20℃, φ=65%)
(4) Simba chairo: rinoreva simba rinoshandiswa neimwe vhoriyamu kuyerera kwecompressor.Iyo imhando yeindekisi yekuongorora iyo compressor mashandiro pasi peiyo yakafanana gasi compression uye yakafanana exhaust pressure.
Simba chairo = simba reshaft (simba rese rekuisa)/ exhaust (kW/m3·min-1)
Shaft simba: Simba rinodiwa kutyaira shaft yecompressor.
P axis =√3×U×I× COS φ(9.5)×η(98%) mota ×η drive
(5), magetsi nemamwe mazwi
Ⅰ, simba: ikozvino pane imwe unit nguva yekuita basa (P), iyo unit iri W (watt
Isu tinowanzo shandisa kW (kilowatt), asiwo simba rebhiza (HP)
1 KW HP1HP = 1.34102 = 0.7357 KW
Ⅱ, ikozvino: yemagetsi pasi pechiito chesimba remagetsi, pane mitemo yekufamba mune imwe nzira
Kana ichifamba, inoumba A ikozvino muA amperes.
Ⅲ, voltage: nekuda kwekuti musoro nemvura inoyerera, pane zvakare mutsauko unogona kuitika,
Inonzi voltage (U), uye iyo unit ndeye V (volts).
Ⅳ, chikamu, inoreva waya, nhanho yechina waya: inoreva nhanho nhatu (kana waya)
Mutsetse wepakati (kana zero line), chikamu chimwe chete chinoreva mutsara wechikamu (kana mutsara wemoto)
Root centre line (kana zero line)
Ⅴ, frequency: alternating ikozvino (ac) kupedzisa iyo electromotive simba reyakanaka uye isina kunaka shanduko inotenderera nhamba yechipiri, shandisa (f), zvinoenderana neyuniti - Hertz (Hz) ye50 Hz inochinjisa yazvino frequency munyika yedu, kunze kwenyika. iri 60Hz.
Ⅵ, frequency: shandura frequency, mumhepo compressor application, nekushandura frequency yesimba kushandura kumhanya kwemota, kuitira kuti uwane chinangwa chekugadzirisa kuyerera.Chiyero chekuyerera chinogona kugadziridzwa ku 0.1bar ne frequency kutendeuka, iyo inoderedza zvakanyanya basa risina basa uye inozadzisa chinangwa chekuchengetedza simba.
Ⅶ, controller: kune maviri makuru marudzi emutongi muindasitiri: chiridzwa rudzi uye PL
Sisitimu, isu tinoshandisa PLC controller, imhando ye
A programmable controller inoumbwa ne single chip microcomputer nezvimwe zvinhu.
Ⅷ, yakatwasuka ligi: yakananga kubatana, mumhepo compressor indasitiri inoreva kusunga nekubatanidza
Ⅸ, kurodha / kuburitsa, iyo inoshanda mamiriro emhepo compressor, kazhinji inoreva kumhepo compressor.
Iyo yakazara nzira yekukweva uye kupera iri munzvimbo yekurodha, zvikasadaro iri mukuburitsa mamiriro
Ⅹ, mhepo / mvura: inoreva nzira yekutonhora
Ⅺ, ruzha: unit: dB (A) (+ 3) (dB) chikamu cheyero yekumanikidza kwenzwi.
Ⅻ, giredhi redziviriro: zvinonzi inodzivirira guruva midziyo yemagetsi, kudzivirira muviri wekunze, kusapinda mvura, nezvimwe.
Kukosha kwechiyero chekudzivirira mhepo kunoratidzwa ne IPXX
Ⅷ, yekutanga modhi: yakananga kutanga, kazhinji tanga nenyeredzi yetatu shanduko nzira.
(6) Dew point tembiricha unit ℃
Mhepo yakanyorova pasi pekumanikidza kwakadai kutonhora, ita kuti pakutanga ine unsaturated mvura mhute mumhepo inove yakazara tembiricha yehutsi, nemamwe mazwi, kana yakaderedzwa kusvika kune imwe tembiricha, tembiricha yemhepo mumhepo ine isina unsaturated mvura mhute kuti isvike saturation state ( kureva kuti chiutsi chinotanga kuita liquefaction, liquid condenses out), tembiricha ndiyo tembiricha yedova regasi.
Pressure dew point: inoreva gasi rine imwe pressure yakatonhodzwa kune imwe tembiricha, iyo isina unsaturated mvura mhute irimo inova saturated water vapor precipitation, tembiricha ndiyo pressure dew point ye gasi.
Atmospheric dova point: payakajairwa atmospheric pressure, gasi rinotonhora zvekuti zviri mukati maro risazare.
Mupfunga wemvura unova wakazara mvura mhute inobuditsa kune tembiricha
Muindasitiri yemhepo compressor, dova danho ndiro dhigirii rekuoma kwegasi
