Litaba

(1), khatello: khatello eo ho buuoang ka eona indastering ea compressor e bua ka khatello (P)

Ⅰ, khatello e tloaelehileng ea sepakapaka (ATM)

Ⅱ, khatello ea ho sebetsa, ho hula, khatello ea ho felloa ke matla, e bolela ho huloa ha compressor ea moea, khatello ea ho tsoa.

① Khatello e lekantsoeng ka khatello ea sepakapaka kaha ntlha ea zero e bitsoa khatello ea holim'a P(G).

② Khatello e nang le vacuum e feletseng kaha ntlha ea zero e bitsoa khatello e feletseng ea P (A).

Khatello ea ho qeta hangata e fanoang ho "compressor nameplate" ke khatello ea gauge.

Ⅲ, khatello e fapaneng, phapang ea khatello

Ⅳ, tahlehelo ea khatello: tahlehelo ea khatello

Ⅴ, compressor ea moea, phetoho ea yuniti ea khatello e sebelisoang hangata:

1MPa (MPa) =106Pa (PASCAL)

1bar (bar) =0.1MPa

1atm (khatello e tloaelehileng ea sepakapaka) =1.013bar=0.1013MPa

Hangata indastering ea compressor ea moea, "kg" e bolela "bar".

(2), phallo ea lebitso: phallo ea lebitso China e boetse e tsejoa e le phallo ea phallo kapa phallo ea mabitso.

Ka kakaretso, tlas'a khatello e hlokahalang ea ho ntša metsi, molumo oa khase o ntšitsoeng ke compressor ea moea ka nako ea yuniti e fetoloa ho boemo ba ho noa, e leng boleng ba molumo oa khatello ea ho hula le mocheso le mongobo mothating oa pele oa phala e kenang. Nako ea unit e bolela motsotso o le mong.

Ke hore, bophahamo ba modumo Q= CM *λ*D3*N=L/D*D3N

L: Bolelele ba rotor

D: Bophara ba rotor

N: Lebelo la shaft la rotor

CM: Coefficient of profile line

Lambda: bolelele ho isa ho bophara ba karolelano

Ho ea ka maemo a naha, palo ea 'nete ea ho tima ea compressor ea moea ke ± 5% ea phallo ea lebitso.

Boemo ba tšupiso: khatello e tloaelehileng ea sepakapaka, mocheso oa 20 ℃, mongobo ke 0℃, sebaka sena sa litšupiso United States, Brithani, Australia le linaheng tse ling tse buang Senyesemane T =15℃. Europe le Japane T =0℃.

Boemo bo tloaelehileng: sepakapaka se le seng se tloaelehileng, mocheso 0 ℃, mongobo 0

Haeba e fetoleloa ho boemo ba motheo, yuniti ke :m3/min (cubic ka motsotso)

Haeba e fetoleloa ho boemo bo tloaelehileng, yuniti ke :Nm3/min (sekwere se tloaelehileng ka motsotso)

Ka mor'a 1 m/min = 1000 l/min

1 nm ka mor'a/metsotso ka mor'a = 1.07 m/min

(3) Likahare tsa oli tsa khase:

Ⅰ, ka unit e ngoe le e ngoe ea moea o hatelitsoeng ka har'a oli (ho kenyeletsoa oli, likaroloana tse emisitsoeng le mouoane oa oli), boleng ba phetoho ho tloha khatellong ea 0.1 MPa, mocheso ke 20 ℃ le mongobo o lekanyelitsoeng oa 65% boleng ba maemo. maemo a sepakapaka. Yuniti :mg/m3 (e bua ka boleng ba para e felletseng)

Ⅱ, PPM e boletse hore ho latella lintho tse ka har'a motsoako oa matšoao, ho bolela palo ea milione e 'ngoe le e 'ngoe ea limilione tse makholo (boima ho feta PPMw le bophahamo ho feta PPMv). (e bua ka karo-karolelano)

Hangata re bua ka PPM e le tekanyo ea boima ba 'mele. (Koloi e le 'ngoe ea milione ke milligram)

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

(4) Matla a khethehileng: a bolela matla a sebelisoang ke phallo e itseng ea molumo oa compressor. Ke mofuta oa index ea ho lekola ts'ebetso ea compressor tlasa khatello e tšoanang ea khase le khatello e ts'oanang ea ho tsoa.

Matla a khethehileng = matla a shaft (kakaretso ea matla a kenyang)/ exhaust (kW/m3·min-1)

Shaft power: Matla a hlokahalang ho khanna shaft ea compressor.

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

(5), motlakase le mantsoe a mang

Ⅰ, matla: hajoale ka nako ea yuniti ho etsa mosebetsi (P), yuniti ke W (watt

Hangata re sebelisa kW (kilowatt), empa hape le matla a lipere (HP)

1 KW HP1HP = 1.34102 = 0.7357 KW

Ⅱ, hona joale: elektronike tlas'a ketso ea matla a matla a motlakase, ho na le melao ea ho tsamaea ka tsela e le 'ngoe

Ha e tsamaea, e theha A current ho A ampere.

Ⅲ, voltage: hobane feela ho na le phallo ea hlooho le metsi, ho boetse ho na le phapang e ka bang teng,

E bitsoa voltage (U), 'me yuniti ke V (volts).

Ⅳ, phase, e bua ka terata, terata ea mekhahlelo e meraro: e bua ka khoele ea mekhahlelo e meraro (kapa terata)

Mohala o bohareng (kapa mohala oa zero), mohato o le mong o bolela mola oa mohato (kapa mohala oa mollo)

Root center line (kapa zero line)

Ⅴ, frequency: alternating current (ac) ho phethela matla a electromotive a potoloho e ntle le e mpe ea phetoho palo ea bobeli, sebelisa (f), ho latela unit - Hertz (Hz) ea 50 Hz e feto-fetohang khafetsa naheng ea rona, kantle ho naha. ke 60Hz.

Ⅵ, frequency: fetola maqhubu, ts'ebetsong ea compressor ea moea, ka ho fetola maqhubu a matla ho fetola lebelo la enjene, e le ho fihlela sepheo sa phetoho ea phallo. Sekhahla sa phallo se ka fetoloa ho 0.1bar ka phetoho ea khafetsa, e fokotsang haholo mosebetsi o sa sebetseng le ho fihlela sepheo sa ho boloka matla.

Ⅶ, molaoli: ho na le mefuta e 'meli ea mantlha ea molaoli indastering: mofuta oa sesebelisoa le PL

Sistimi, re sebelisa molaoli oa PLC, ke mofuta oa ka

Taolo e hlophisehileng e entsoeng ka microcomputer e le 'ngoe le likarolo tse ling.

Ⅷ, selekane se otlolohileng: khokahano e otlolohileng, indastering ea compressor ea moea e bua ka ho tlama ka ho kopanya

Ⅸ, ho kenya / ho laolla, boemo ba ho sebetsa ba compressor ea moea, ka kakaretso e bua ka compressor ea moea.

Ts'ebetso e felletseng ea ho hula le ho khathala e maemong a ho roala, ho seng joalo e maemong a ho theola

Ⅹ, moea/metsi: e bua ka tsela e pholileng

Ⅺ, lerata: yuniti: dB (A) (+ 3) (dB) yuniti ea boemo ba khatello ea molumo

Ⅻ, boemo ba ts'ireletso: ho thoe lisebelisoa tsa motlakase tse sa keneleng lerole, li thibela 'mele oa kantle ho naha, tse sa keneleng metsi, jj.

Boleng ba tekanyo ea ho thibela moea e hlahisoa ke IPXX

Ⅷ, mokhoa oa ho qala: qala ka kotloloho, hangata qala ka mokhoa oa phetoho ea khutlotharo ea linaleli.

(6) yuniti ea mocheso oa phoka ℃

Moea o metsi tlas'a khatello e joalo ea pholileng, o etsa hore qalong o na le mouoane oa metsi o sa tsitsang moeeng o fetoha mocheso o tletseng mouoane, ka mantsoe a mang, ha o fokotsehile ho mocheso o itseng, mocheso oa moea o moeeng o na le mouoane oa metsi o sa tsitsang ho fihlela boemo ba saturation. e leng mouoane qala ho liquefaction, mokelikeli condenses tsoa), mocheso ke phoka ntlha mocheso oa khase.

Khatello ea phoka: e bua ka khase e nang le khatello e itseng e pholileng mocheso o itseng, mouoane oa metsi o sa saturated o teng ho oona o fetoha mouoane oa metsi, mocheso ke phoka ea khatello ea khase.

Sebaka sa phoka ea atmospheric: tlas'a khatello e tloaelehileng ea sepakapaka, khase e ea phophoma e le hore likahare tsa eona li se ke tsa tlala.

Mouoane oa metsi o fetoha mouoane o tletseng metsi o tsoang ho mocheso

Indastering ea compressor ea moea, phoka ke tekanyo ea ho omella ha khase
