Nkhani

(1), kupanikizika: kupanikizika komwe kumatchulidwa mumakampani a kompresa kumatanthauza kukakamiza (P)

Ⅰ, standard atmospheric pressure (ATM)

Ⅱ, kuthamanga kwa ntchito, kuyamwa, kuthamanga kwa mpweya, kumatanthauza kuyamwa kwa kompresa, kuthamanga kwa mpweya.

① Kuthamanga koyezedwa ndi mpweya wa mumlengalenga monga zero point imatchedwa kuthamanga kwa pamwamba P (G).

② Kupanikizika kokhala ndi vacuum mtheradi pomwe zero point imatchedwa absolute pressure P (A).

Kuthamanga kwa mpweya nthawi zambiri kumaperekedwa pa dzina la compressor nameplate ndi mphamvu ya gauge.

Ⅲ, kuthamanga kosiyana, kusiyana kwa kuthamanga

Ⅳ, kutsika kwamphamvu: kutsika kwamphamvu

Ⅴ, kompresa ya mpweya, kutembenuka komwe kumagwiritsidwa ntchito kwambiri:

1MPa (MPa) =106Pa (PASCAL)

1 bala (bala) = 0.1MPa

1atm (kupanikizika mumlengalenga) =1.013bar=0.1013MPa

Nthawi zambiri mumakampani opanga mpweya, "kg" amatanthauza "bar".

(2), kutuluka mwadzina: kutuluka mwadzina ku China kumadziwikanso kuti kusamuka kapena kutulutsa dzina.

Nthawi zambiri, pansi pa mphamvu yotulutsa mpweya wofunikira, voliyumu ya gasi yomwe imatulutsidwa ndi kompresa ya mpweya pa nthawi ya unit imasinthidwa kukhala malo odyetserako, omwe ndi kuchuluka kwa mphamvu yoyamwa ndi kutentha kwa mpweya ndi chinyezi pagawo loyamba la chitoliro cholowetsa.Nthawi ya unit ikutanthauza miniti imodzi.

Ndiko kuti, voliyumu yoyamwa Q= CM *λ*D3*N=L/D*D3N

L: Kutalika kwa rotor

D: Diameter ya rotor

N: Kuthamanga kwa shaft kwa rotor

CM: Coefficient of profile line

Lambda: kutalika mpaka m'mimba mwake

Malinga ndi muyezo wadziko lonse, kuchuluka kwenikweni kwa mpweya wa kompresa ndi ± 5% yakuyenda mwadzina.

Malo otchulirapo: kuthamanga kwa mumlengalenga, kutentha kwa 20 ℃, chinyezi ndi 0 ℃, boma la United States, Britain, Australia ndi mayiko ena olankhula Chingerezi T = 15 ℃.Europe ndi Japan T =0 ℃.

Mkhalidwe wokhazikika: mpweya umodzi wokhazikika, kutentha 0 ℃, chinyezi 0

Ngati atasinthidwa kukhala maziko, gawoli ndi :m3/min (kiyubiki pa mphindi)

Ngati asinthidwa kukhala wokhazikika, gawo ndi :Nm3/mphindi (muyezo sikweya pa mphindi)

Pambuyo pa 1 m/mphindi = 1000 l/mphindi

1 nm pambuyo/mphindi pambuyo = 1.07 m/mphindi

(3) Mafuta a gasi:

Ⅰ, pa unit voliyumu ya wothinikizidwa mpweya mu mafuta (kuphatikiza mafuta, inaimitsidwa particles ndi nthunzi mafuta), khalidwe la kutembenuka kwa mphamvu ya 0.1 MPa, kutentha ndi 20 ℃ ndi chinyezi wachibale wa 65% mtengo wa muyezo mlengalenga.Unit :mg/m3 (amatanthawuza mtengo wokwanira awiriawiri)

Ⅱ, PPM inati zinthu zomwe zili mumsanganizo wa zizindikiro, zimatanthawuza chiwerengero cha miliyoni miliyoni miliyoni (kulemera kuposa PPMw ndi voliyumu kuposa PPMv).(kutengera chiŵerengero)

Nthawi zambiri timatchula PPM ngati chiŵerengero cha kulemera.(Miliyoni imodzi ya kilogalamu ndi milligram)

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

(4) Mphamvu yeniyeni: imatanthawuza mphamvu yomwe imadyedwa ndi kuchuluka kwa voliyumu ya kompresa.Ndi mtundu wa index kuti muwunikire momwe compressor imagwirira ntchito pansi pa kukanikiza kwa gasi komweko komanso kuthamanga komweko.

Mphamvu zenizeni = mphamvu ya shaft (mphamvu zonse zolowetsa)/ utsi (kW/m3·min-1)

Shaft mphamvu: Mphamvu yofunikira kuyendetsa shaft ya kompresa.

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

(5), magetsi ndi mawu ena

Ⅰ, mphamvu: panopa pa unit nthawi yogwira ntchito (P), unit ndi W (watt

Nthawi zambiri timagwiritsa ntchito kW (kilowatt), komanso mphamvu zamahatchi (HP)

1 KW HP1HP = 1.34102 = 0.7357 KW

Ⅱ, panopa: zamagetsi pansi pa mphamvu ya magetsi, pali malamulo osuntha mbali imodzi

Ikasuntha, imapanga A panopa mu A amperes.

Ⅲ, voteji: chifukwa mutu ndi madzi otaya, palinso kusiyana zotheka,

Amatchedwa voteji (U), ndipo unit ndi V (volts).

Ⅳ, gawo, limatanthawuza waya, gawo lachitatu la waya: limatanthawuza ulusi wa magawo atatu (kapena waya)

Mzere wapakati (kapena mzere wa zero), gawo limodzi limatanthawuza mzere wa gawo (kapena mzere wamoto)

Root center line (kapena zero line)

Ⅴ, ma frequency: alternating current (ac) kuti amalize mphamvu ya electromotive ya kusintha kwabwino ndi koyipa nambala yachiwiri, gwiritsani ntchito (f), malinga ndi gawo - Hertz (Hz) ya 50 Hz yosinthira ma frequency apano mdziko lathu, kunja ndi 60hz.

Ⅵ, ma frequency: sinthani ma frequency, mukugwiritsa ntchito kompresa ya mpweya, posintha ma frequency amphamvu kuti musinthe liwiro la mota, kuti mukwaniritse cholinga chakusintha koyenda.Kuthamanga kumatha kusinthidwa kukhala 0.1bar ndi kutembenuka pafupipafupi, komwe kumachepetsa kwambiri ntchito yopanda ntchito ndikukwaniritsa cholinga chopulumutsa mphamvu.

Ⅶ, wowongolera: pali mitundu iwiri ikuluikulu ya owongolera mumakampani: mtundu wa zida ndi PL

System, timagwiritsa ntchito PLC controller, ndi mtundu wa

Chowongolera chokhazikika chopangidwa ndi chip microcomputer imodzi ndi zida zina.

Ⅷ, mgwirizano wowongoka: kulumikizana kwachindunji, mumakampani opanga ma compressor amatanthauza kumanga ndi kulumikizana

Ⅸ, kutsitsa / kutsitsa, momwe mpweya umagwirira ntchito, nthawi zambiri zimatanthawuza kompresa ya mpweya.

Njira yonse yoyamwa ndi kutulutsa ili m'malo otsitsa, apo ayi ili pakutsitsa

Ⅹ, mpweya/madzi: amatanthauza njira yozizira

Ⅺ, phokoso: chigawo: dB (A) (+ 3) (dB) yuniti ya mphamvu ya mawu

Ⅻ, chitetezo kalasi: akuti zida fumbi magetsi, kuteteza thupi lachilendo, madzi, etc.

Mtengo wa digiri ya kutsekeka kwa mpweya umawonetsedwa ndi IPXX

Ⅷ, njira yoyambira: yoyambira molunjika, nthawi zambiri imayamba ndi njira yosinthira nyenyezi.

(6) Mame mfundo kutentha unit ℃

Mpweya wonyowa pansi pa kuzizira kotereku, umapanga poyamba uli ndi nthunzi yamadzi yopanda madzi mumlengalenga imakhala yodzaza kutentha kwa nthunzi, mwa kuyankhula kwina, ikatsitsidwa ku kutentha kwina, kutentha kwa mpweya mumlengalenga kumakhala ndi nthunzi yamadzi yopanda madzi kuti ifike ku machulukitsidwe mkhalidwe ( ndicho nthunzi akuyamba liquefaction, madzi condenses kunja), kutentha ndi mame mfundo kutentha kwa mpweya.

Pressure point: imatanthawuza mpweya womwe umakhala ndi kuthamanga kwina kokhazikika ku kutentha kwina, nthunzi yamadzi yopanda madzi yomwe ili mmenemo imakhala mpweya wodzaza ndi mpweya, kutentha ndi kupanikizika kwa mame a mpweya.

Mame am'mlengalenga: Pakuthamanga kwa mumlengalenga, mpweya umazizira kotero kuti zomwe zili mkati mwake sizidzadza.

Nthunzi yamadzi imakhala yodzaza ndi nthunzi yamadzi yotulutsa mpweya ku kutentha

M'makampani opangira mpweya, mame ndi kuchuluka kwa kuuma kwa gasi
