Ifomula yokubala ye-compressor yomoya kanye nomgomo!
Njengonjiniyela oprakthiza wama-compressor emoyeni, ngaphezu kokuqonda ukusebenza komkhiqizo wenkampani yakho, ezinye izibalo ezihilelekile kulesi sihloko nazo zibalulekile, ngaphandle kwalokho, isizinda sakho sobuchwepheshe sizophaphatheka kakhulu.
(Umdwebo wohlelo, ongahambelani nanoma yimuphi umkhiqizo othile esihlokweni)
1. Ukukhishwa kokuguqulwa kweyunithi “kwesikwele esijwayelekile” kanye “ne-cubic”
1Nm3/min (isikwele esijwayelekile) s1.07m3/min
Ngakho, lokhu kuguqulwa kwenzeka kanjani?Mayelana nencazelo yesikwele esijwayelekile kanye ne-cubic:
pV=nRT
Ngaphansi kwalezi zifunda ezimbili, ingcindezi, inani lezinto, kanye nama-constants kuyafana, futhi umehluko kuphela izinga lokushisa (izinga lokushisa le-thermodynamic K) lithathwa: Vi/Ti=V2/T2 (okungumthetho we-Gay Lussac)
Cabanga ukuthi: i-V1, i-Ti amakhyubhu ajwayelekile, i-V2, i-T2 amakhyubhu
Bese: V1: V2=Ti: T2
Okungukuthi: Vi: Vz=273: 293
Ngakho: Vis1.07V2
Umphumela: 1Nm3/mins1.07m3/min
Okwesibili, zama ukubala ukusetshenziswa kukaphethiloli kwe-compressor yomoya
Nge-compressor yomoya enamandla angu-250kW, 8kg, ukususwa kuka-40m3/min, nokuqukethwe kukawoyela okungu-3PPM, mangaki amalitha kawoyela azosetshenziswa iyunithi ngokwethiyori uma isebenza amahora angu-1000?
impendulo:
Ukusetshenziswa kukaphethiloli nge-cubic meter ngayinye ngomzuzu:
3x 1.2=36mg/m3
, 40 cubic metres ngomzuzu ukusetshenziswa kukaphethiloli:
40×3.6/1000=0.144g
Ukusetshenziswa kukaphethiloli ngemva kokusebenza amahora angu-1000:
-1000x60x0.144=8640g=8.64kg
Iguqulelwe kuvolumu 8.64/0.8=10.8L
(Ukubaluleka kwamafutha okugcoba cishe ku-0.8)
Okungenhla kuphela ukusetshenziswa kukaphethiloli okucatshangelwayo, empeleni kukhulu kunaleli xabiso (isihlungi esiyinhloko sesihlukanisi samafutha siyaqhubeka nokuncipha), uma sibalwa ngokusekelwe emahoreni angu-4000, i-compressor yomoya engu-40 cubic izosebenzisa okungenani amalitha angu-40 (imiphongolo emibili) wamafutha.Ngokuvamile, imiphongolo engaba ngu-10-12 (amalitha angu-18 / umgqomo) ifakwe uphethiloli ekugcinweni ngakunye kwe-compressor yomoya engamamitha-skwele angama-40, futhi ukusetshenziswa kukaphethiloli cishe ku-20%.
3. Ukubalwa komthamo wegesi ethafeni
Bala ukugudluka kwe-compressor yomoya ukusuka ethafeni ukuya ethafeni:
Ifomula yokucaphuna:
V1/V2=R2/R1
V1=ivolumu yomoya endaweni engenalutho, V2=ivolumu yomoya endaweni yethafa
R1=isilinganiso sokucindezela sethafa, R2=isilinganiso sokucindezela sethafa
Isibonelo: I-compressor yomoya ingu-110kW, i-exhaust pressure ingu-8bar, futhi izinga lokugeleza kwevolumu ngu-20m3/min.Kuyini ukufuduka kwale modeli endaweni engamamitha angama-2000?Bheka ithebula le-barometric elihambisana nokuphakama)
Isixazululo: Ngokwefomula ethi V1/V2= R2/R1
(ilebula 1 licacile, 2 liyithafa)
V2=ViR1/R2R1=9/1=9
R2=(8+0.85)/0.85=10.4
V2=20×9/10.4=17.3m3/min
Khona-ke: umthamo wokukhipha lo modeli ngu-17.3m3 / min endaweni yokuphakama kwamamitha angu-2000, okusho ukuthi uma le compressor yomoya isetshenziswa ezindaweni ze-plateau, umthamo wokukhipha uzoncishiswa kakhulu.
Ngakho-ke, uma amakhasimende asezindaweni zasemathafeni edinga inani elithile lomoya ocindezelweyo, adinga ukunaka ukuthi ukususwa kwe-compressor yethu yomoya kungahlangabezana yini nezidingo ngemuva kokuncishiswa kokuphakama okuphezulu.
Ngesikhathi esifanayo, amakhasimende amaningi abeka phambili izidingo zawo, ikakhulukazi lezo eziklanywe isikhungo sokuklama, athanda njalo ukusebenzisa iyunithi ye-Nm3/min, futhi adinga ukunaka ukuguqulwa ngaphambi kokubala.
4. Ukubalwa kwesikhathi sokugcwalisa i-compressor yomoya
Kuthatha isikhathi esingakanani ukuthi i-compressor yomoya igcwalise ithangi?Yize lesi sibalo singelona usizo kakhulu, asinembile futhi singaba ukuhlawumbisela okuhle kakhulu.Kodwa-ke, abasebenzisi abaningi basazimisele ukuzama le ndlela ngenxa yokungabaza mayelana nokugudluzwa kwangempela kwe-compressor yomoya, ngakho-ke kusenezimo eziningi zalesi sibalo.
Esokuqala isimiso salesi sibalo: empeleni ukuguqulwa kwevolumu yezifunda ezimbili zegesi.Okwesibili yisizathu sephutha elikhulu lokubala: okokuqala, asikho isimo sokulinganisa idatha edingekayo esizeni, njengezinga lokushisa, ngakho-ke singanakwa kuphela;okwesibili, ukusebenza kwangempela kokulinganisa akukwazi ukunemba, njengokushintshela kusimo sokugcwalisa.
Nokho, noma kunjalo, uma kunesidingo, sisadinga ukwazi ukuthi hlobo luni lwendlela yokubala:
Isibonelo: Kuthatha isikhathi esingakanani ukuthi i-compressor yomoya engu-10m3/min, 8bar igcwalise ithangi lokugcina igesi elingu-2m3?Incazelo: Yini egcwele?Okusho ukuthi, i-compressor yomoya ixhunywe ne-2 cubic metres yokugcina igesi, kanye ne-valve yokugcina igesi yokukhipha igesi Ivale kuze kube yilapho i-compressor yomoya ishaya ibha engu-8 ukuze ikhiphe, futhi ingcindezi yegeji yebhokisi lokugcina igesi nayo i-8 bar. .Sithatha isikhathi esingakanani lesi sikhathi?Qaphela: Lesi sikhathi sidinga ukubalwa kusukela ekuqaleni kokulayisha i-compressor yomoya, futhi asikwazi ukufaka ukuguqulwa kwangaphambilini kwenkanyezi-delta noma inqubo yokuguqulwa kwe-frequency up-converter.Yingakho umonakalo wangempela owenziwe esizeni awukwazi ukunemba.Uma kukhona indlela yokudlula epayipini elixhunywe ku-compressor yomoya, iphutha liyoba lincane uma i-compressor yomoya ilayishwe ngokugcwele futhi ishintshelwe ngokushesha epayipini lokugcwalisa ithangi lokugcina umoya.
Okokuqala indlela elula (isilinganiso):
Ngaphandle kwezinga lokushisa:
piVi=pzVz (Boyle-Malliot Law) Ngale fomula, kutholakala ukuthi ukuguqulwa kwevolumu yegesi empeleni kuyisilinganiso sokucindezela
Bese: t=Vi/ (V2/R) imiz
(Inombolo 1 umthamo wethangi lokugcina umoya, futhi 2 ukugeleza kwevolumu ye-compressor yomoya)
t=2m3/ (10m3/9) min= 1.8min
Kuthatha cishe amaminithi angu-1.8 ukushaja ngokugcwele, noma cishe iminithi elingu-1 namasekhondi angu-48
