Ikirere cyo guhumeka ikirere hamwe nihame!
Nka injeniyeri ukora imyitozo ya compressor de air, usibye gusobanukirwa imikorere yibicuruzwa bya sosiyete yawe, kubara bimwe muriki kiganiro nabyo ni ngombwa, bitabaye ibyo, umwuga wawe wumwuga uzaba mwiza cyane.
(Igishushanyo mbonera, ntabwo gihuye nibicuruzwa runaka mu ngingo)
1. Inkomoko yo guhindura ibice bya "kare kare" na "cubic"
1Nm3 / min (kare kare) s1.07m3 / min
None, uko guhinduka kwabayeho gute?Kubijyanye nubusobanuro bwa kare kare na cubic:
pV = nRT
Muri leta zombi, igitutu, ingano yibintu, hamwe nibihinduka ni bimwe, kandi itandukaniro ni ubushyuhe gusa (ubushyuhe bwa termodinamike K) hacibwa: Vi / Ti = V2 / T2 (ni ukuvuga amategeko ya Gay Lussac)
Dufate: V1, Ti ni cubes zisanzwe, V2, T2 ni cubes
Hanyuma: V1: V2 = Ti: T2
Nibyo: Vi: Vz = 273: 293
Noneho: Vis1.07V2
Igisubizo: 1Nm3 / mins1.07m3 / min
Icya kabiri, gerageza kubara lisansi ikoreshwa na compressor de air
Kuri compressor de air ifite 250kW, 8kg, kwimura 40m3 / min, hamwe namavuta ya 3PPM, litiro zingahe zamavuta igice kizakoresha mubyukuri niba gikora amasaha 1000?
igisubizo:
Gukoresha lisansi kuri metero kibe kumunota:
3x 1.2 = 36mg / m3
, Metero kibe 40 kumunota ukoresha lisansi:
40 × 3.6 / 1000 = 0.144g
Gukoresha lisansi nyuma yo gukora amasaha 1000:
-1000x60x0.144 = 8640g = 8.64kg
Yahinduwe mububiko 8.64 / 0.8 = 10.8L
(Ibyingenzi byamavuta yo gusiga ni 0.8)
Ibyavuzwe haruguru nuburyo bukoreshwa bwa peteroli gusa, mubyukuri birarenze agaciro kayo (amavuta yo gutandukanya amavuta akayunguruzo akomeje kugabanuka), iyo ubaze ukurikije amasaha 4000, compressor de cubic 40 ikora byibura litiro 40 (barrele ebyiri) y'amavuta.Mubisanzwe, hafi ya barrile 10-12 (litiro 18 / barrele) zongerwamo lisansi kuri buri kubungabunga imashini ya metero kare 40 ya compressor yo mu kirere, kandi ikoreshwa rya lisansi ni 20%.
3. Kubara ingano ya gaze ya plateau
Kubara iyimurwa rya compressor yo mu kirere kuva mu kibaya kugera mu kibaya:
Inzira yatanzwe:
V1 / V2 = R2 / R1
V1 = ingano yumwuka mubice bisanzwe, V2 = ingano yumwuka mukarere ka plateau
R1 = igipimo cyo guhunika cyibisanzwe, R2 = igipimo cyo kwikuramo cya plateau
Urugero: Compressor yo mu kirere ni 110kW, umuvuduko ukabije ni 8bar, naho umuvuduko wijwi ni 20m3 / min.Ni ubuhe buryo bwo kwimura iyi moderi ku butumburuke bwa metero 2000?Reba imbonerahamwe ya barometrike ihuye nuburebure)
Igisubizo: Ukurikije formula V1 / V2 = R2 / R1
(label 1 irasobanutse, 2 ni plateau)
V2 = ViR1 / R2R1 = 9/1 = 9
R2 = (8 + 0.85) /0.85=10.4
V2 = 20 × 9 / 10.4 = 17.3m3 / min
Noneho: ingano yumuriro wiyi moderi ni 17.3m3 / min ku butumburuke bwa metero 2000, bivuze ko niba iyi compressor yo mu kirere ikoreshejwe ahantu h'ibibaya, ubwinshi bw’umwuka buzaba bwiyongereye cyane.
Kubwibyo, niba abakiriya mubice bya plateau bakeneye umubare munini wumwuka uhumeka, bakeneye kwitondera niba kwimura compressor yacu yo mu kirere bishobora kuzuza ibisabwa nyuma yuburebure bwo hejuru.
Muri icyo gihe, abakiriya benshi bashyira imbere ibyo bakeneye, cyane cyane byashizweho n'ikigo cyashushanyaga, burigihe bakunda gukoresha igice cya Nm3 / min, kandi bakeneye kwitondera ihinduka mbere yo kubara.
4. Kubara igihe cyo kuzuza compressor de air
Bifata igihe kingana iki kugirango compressor yo mu kirere yuzuze tank?Nubwo iyi mibare idakenewe cyane, ntabwo arukuri kandi irashobora kuba ikigereranyo cyiza.Nyamara, abakoresha benshi baracyafite ubushake bwo kugerageza ubu buryo kubera gushidikanya kubyerekeranye no kwimuka kwukuri kwa compressor de air, bityo haracyari ibintu byinshi kuriyi mibare.
Iya mbere ni ihame ryiyi mibare: mubyukuri ni ihinduka ryijwi ryibihugu byombi bya gaze.Iya kabiri nimpamvu yikosa rinini ryo kubara: icya mbere, ntamwanya uhari wo gupima amakuru amwe akenewe kurubuga, nkubushyuhe, bityo birashobora kwirengagizwa gusa;icya kabiri, imikorere nyayo yo gupima ntishobora kuba impamo, nko guhinduranya kuri Kuzuza imiterere.
Nubwo bimeze bityo ariko, niba hari ibikenewe, turacyakeneye kumenya ubwoko bwuburyo bwo kubara:
Urugero: Bifata igihe kingana iki kugirango 10m3 / min, 8bar compressor yo mu kirere yuzuze ikigega cya gaze 2m3?Ibisobanuro: Niki cyuzuye?Nukuvuga ko compressor yo mu kirere ihujwe na metero kibe 2 zo kubika gaze, hamwe na gaze yo kubika gaze ya gaze ya finale Ifunga kugeza igihe compressor yo mu kirere ikubise akabari 8 kugirango yipakurure, kandi umuvuduko wapima agasanduku ka gaze nawo ni 8 bar .Iki gihe gifata igihe kingana iki?Icyitonderwa: Iki gihe gikeneye kubarwa uhereye igihe cyo gutangira kwipakurura ikirere, kandi ntigishobora gushyiramo inyenyeri-delta yabanjirije cyangwa inzira yo guhinduranya inshuro nyinshi.Niyo mpamvu ibyangiritse nyirizina byakozwe kurubuga bidashobora kuba ukuri.Niba hari inzira nyabagendwa mu muyoboro uhujwe na compressor yo mu kirere, ikosa rizaba rito niba compressor yo mu kirere yuzuye kandi igahita ihindurwamo umuyoboro kugirango yuzuze ikigega kibika ikirere.
Ubwa mbere inzira yoroshye (igereranya):
Utitaye ku bushyuhe:
piVi = pzVz (Amategeko ya Boyle-Malliot) Binyuze muri iyi formula, usanga ihinduka ryubunini bwa gaze mubyukuri ari igipimo cyo kwikuramo
Hanyuma: t = Vi / (V2 / R) min
(Umubare 1 nubunini bwikigega cyo kubika ikirere, na 2 nubunini bwikigereranyo cya compressor de air)
t = 2m3 / (10m3 / 9) min = 1.8min
Bifata iminota 1.8 kugirango yishyure byuzuye, cyangwa umunota 1 n'amasegonda 48
hakurikiraho gato algorithm igoye
ku gipimo cyo gupima)
sobanura
Q0 - Compressor ingano itemba m3 / min idafite kondensate:
Vk - ingano ya tank m3:
T - igihe cyo guta agaciro min;
px1 - compressor yo guswera MPa:
Tx1 - ubushyuhe bwo gukuramo ubushyuhe K:
pk1 - igitutu cya gaze MPa mubigega byo kubika gaze mugitangira ifaranga;
pk2 - Umuvuduko wa gazi MPa mubigega byo kubika gaze nyuma yo guta agaciro kwifaranga nuburinganire:
Tk1 - ubushyuhe bwa gaze K muri tank mugitangira kwishyuza:
Tk2 - Ubushyuhe bwa gaze K mububiko bwa gaze nyuma yo kwishyuza gaze hamwe nuburinganire bwumuriro
Tk - ubushyuhe bwa gaze K muri tank.
5. Kubara Ikoreshwa ryikirere ryibikoresho bya pneumatike
Uburyo bwo kubara ikirere cyo gukoresha uburyo bwa sisitemu yo mu kirere ya buri gikoresho cya pneumatike iyo ikora rimwe na rimwe (gukoresha ako kanya no guhagarara):
Qmax- ikirere ntarengwa cyo gukoresha ikirere gikenewe
Umusozi - ikintu cyo gukoresha.Ireba coefficient ko ibikoresho byose bya pneumatike bitazakoreshwa icyarimwe.Agaciro keza ni 0,95 ~ 0,65.Mubisanzwe, uko umubare wibikoresho bya pneumatike, niko gukoreshwa icyarimwe, kandi agaciro gake, naho ubundi agaciro kanini.0.95 kubikoresho 2, 0.9 kubikoresho 4, 0,85 kubikoresho 6, 0.8 kubikoresho 8, na 0,65 kubikoresho birenga 10.
K1 - Coefficient yamenetse, agaciro katoranijwe imbere mu gihugu kuva 1.2 kugeza 15
K2 - Coefficient isanzwe, agaciro katoranijwe murwego rwa 1.2 ~ 1.6.
K3 - Coefficient idahwanye
Ireba ko hari ibintu bitaringaniye mukubara ikigereranyo cya gaze ikoreshwa muri sisitemu ya gaze, kandi igashyirwaho kugirango ikoreshwe cyane, kandi agaciro kayo ni 1.2
~ 1.4 Guhitamo abafana murugo.
6. Iyo ingano yumwuka idahagije, bara itandukaniro ryijwi ryikirere
Bitewe n'ubwiyongere bw'ibikoresho bikoresha ikirere, itangwa ry'ikirere ntirihagije, kandi ni bangahe bigomba kongerwaho compressor zo mu kirere kugira ngo umuvuduko w'akazi ugenwe urashobora guhazwa.formula:
Q Real - igipimo cyo guhumeka ikirere gisabwa na sisitemu munsi yukuri,
QOriginal - umuvuduko wabagenzi wa compressor yumwimerere;
Amasezerano - igitutu MPa ishobora kugerwaho mubihe bifatika;
P umwimerere - igitutu cyakazi MPa ishobora kugerwaho no gukoresha umwimerere;
AQ- volumetric itemba kugirango yiyongere (m3 / min)
Urugero: Umwuka wo guhumeka wumwimerere ni metero kibe 10 na kg 8.Umukoresha yongerera ibikoresho kandi umuvuduko woguhumeka ikirere urashobora gukubita kg 5 gusa.Baza, umubare wogukwirakwiza ikirere ukeneye kongerwaho kugirango uhuze ikirere cya kg 8.
AQ = 10 * (0.8-0.5) / (0.5 + 0.1013)
s4.99m3 / min
Kubwibyo: compressor yo mu kirere ifite kwimura byibura metero kibe 4.99 na kilo 8.
Mubyukuri, ihame ryiyi formula ni: mukubara itandukaniro nigitutu cyintego, irabaze igipimo cyumuvuduko uriho.Iri gereranya rikoreshwa ku kigero cyo gutembera kwikirere gikoreshwa muri iki gihe, ni ukuvuga, agaciro kavuye ku gipimo cyagenwe kiboneka.
