Habka wax-soo-saarka warshadaha iyo wax-soo-saarka, qaar ka mid ah taangiyada la cabbiray way fududahay in la miirto, aad u muuqo badan, aad u daxaleeyo, oo ay fududahay in la adkeeyo.Gudbiyeyaasha cadaadiska kala duwan ee hal iyo laba flange ayaa inta badan la adeegsadaa waqtiyadan., Sida: taangiyada, munaaradaha, killiyadaha, iyo taangiyada dhirta coking;haamaha kaydinta dareeraha ah ee wax soo saarka unugyada uumi-baxayaasha, haamaha kaydinta heerka dareeraha ee dhirta desulfurization iyo denitrification.Labada walaal ee hal iyo laba-jibbaaran labaduba waxay leeyihiin codsiyo badan, laakiin way ka duwan yihiin farqiga u dhexeeya furan iyo shaabadeynta.Taangiyada furan ee hal-flange ah waxay noqon karaan taangiyo xiran, halka garbaha labajibbaaran ay leeyihiin taangiyo badan oo xiran dadka isticmaala.
Mabda'a gudbiyaha cadaadiska flange-ka keliya ee cabbiraya heerka dareeraha
Gudbiyaha cadaadiska hal-flange wuxuu sameeyaa beddelaad heer ah isagoo cabbiraya cufnaanta haanta furan, cabbirka heerka weelasha furan
Marka la cabbirayo heerka dareeraha weelka furan, gudbiyaha waxaa lagu rakibaa meel u dhow gunta hoose ee weelka si loo cabbiro cadaadiska u dhigma dhererka heerka dareeraha ee ka sarreeya.Sida ku cad sawirka 1-1.
Cadaadiska heerka dareeraha weelka wuxuu ku xiran yahay dhinaca cadaadiska sare ee gudbiyaha, dhinaca cadaadiska hooseeya wuxuu u furan yahay jawiga.
Haddii heerka dareeraha ugu hooseeya ee cabbirka isbeddelka heerka dareeraha la qiyaasay uu ka sarreeyo meesha lagu rakibay gudbiyaha, gudbiyaha waa inuu sameeyaa guuritaan togan.
Jaantuska 1-1 Tusaalaha cabbiraadda dareeraha weelka furan
X ha ahaado masaafada toosan ee u dhaxaysa heerka dareeraha ugu hooseeya iyo kan ugu sarreeya ee la cabbirayo, X=3175mm.
Y waa fogaanta toosan ee u jirta dekedda cadaadiska gudbiyaha ilaa heerka dareeraha ugu hooseeya, y=635mm.ρ waa cufnaanta dareeraha, ρ=1.
h waa madaxa cadaadiska ugu badan ee uu soo saaro tiirka dareeraha X, ee KPa.
e waa madaxa cadaadiska uu soo saaro tiirka dareeraha Y, ee KPa.
1mH2O=9.80665Pa (la mid ah hoos)
Qiyaasta cabbirku waa e ilaa e+h sidaa darteed: h=X·ρ=3175×1=3175mmH2O=31.14KPa
e=y·ρ=635×1= 635mmH2O= 6.23KPa
Taasi waa, cabbirka cabbiraadda gudbiyaha waa 6.23KPa～37.37KPa
Marka la soo koobo, waxaan dhab ahaantii cabbirnaa dhererka heerka dareeraha:
Dhererka heerka dareeraha H=(P1-P0)/(ρ*g)+D/(ρ*g);
Fiiro gaar ah: P0 waa cadaadiska atmospheric hadda;
P1 waa qiimaha cadaadiska ee lagu cabbirayo dhinaca cadaadiska sare;
D waa tirada socdaalka eber.
Mabda'a gudbiyaha cadaadiska flange double ee cabbiraya heerka dareeraha
Gudbiyaha cadaadiska laba-flange wuxuu fuliyaa beddelaad heer ah isagoo cabbiraya cufnaanta haanta xiran: Xiriirka qallayl
Haddii gaaska ka sarreeya dusha dareeraha ahi aanu isku ururin, tuubada isku xidha ee dhinaca cadaadiska hoose ee gudbiyaha ayaa ahaanaysa mid qalalan.Xaaladdan waxaa lagu magacaabaa isku xirka duuliyaha qalalan.Habka lagu go'aaminayo cabbirka cabbirka gudbiyaha wuxuu la mid yahay heerka dareeraha weelka furan.(Fiiri sawirka 1-2).
Haddii gaaska dareeraha ah uu isku ururiyo, dareeruhu wuxuu si tartiib tartiib ah ugu ururin doonaa tuubada hagta cadaadiska ee dhinaca cadaadiska hooseeya ee gudbiyaha, taas oo keeni doonta khaladaadka cabbirka.Si loo baabi'iyo qaladkan, ka hor ku buuxi tuubada haga cadaadiska hoose ee dhexdhexaadiyaha leh dareere gaar ah.Xaaladdan waxaa lagu magacaabaa isku xirka hagida cadaadiska qoyan.
Xaaladda kor ku xusan, waxaa jira madaxa cadaadis dhinaca cadaadiska hooseeya ee gudbiyaha, sidaas darteed guuritaanka taban waa in la sameeyaa (eeg sawirka 1-2)
Jaantuska 1-2 Tusaalaha cabbiraadda dareeraha ee weel xiran
X ha ahaado masaafada toosan ee u dhaxaysa heerka dareeraha ugu hooseeya iyo kan ugu sarreeya ee la cabbirayo, X=2450mm.Y waa fogaanta toosan ee u jirta dekedda cadaadiska gudbiyaha ilaa heerka dareeraha ugu hooseeya, Y=635mm.
Z waa masaafada kore ee tuubada haga cadaadiska dareeraha ka buuxo ilaa xariiqda saldhiga gudbiyaha, Z=3800mm,
ρ1 waa cufnaanta dareeraha, ρ1=1.
ρ2 waa cufnaanta dareeraha buuxinaya mareenka dhinaca cadaadiska hooseeya, ρ1=1.
h waa madaxa cadaadiska ugu badan ee ay soo saarto tiirka dareeraha X ee la tijaabiyay, ee KPa.
e waa madaxa cadaadiska ugu badan ee ay soo saarto tiirka dareeraha Y ee la tijaabiyey, gudaha KPa.
s waa madaxa cadaadiska uu soo saaro tiirka dareeraha ee Z, ee KPa.
Qiyaasta cabbirku waa laga bilaabo (es) ilaa (h+es), ka dib
h=X·ρ1=2540×1=2540mmH2O =24.9KPa
e=Y·ρ1=635×1=635mmH2O =6.23KPa
s=Z·ρ2=3800×1=3800mmH2O=37.27KPa
Haddaba: es=6.23-37.27=-31.04KPa
h+e = 24.91+6.23 -37.27= -6.13KPa
Fiiro gaar ah: Marka la soo koobo, waxaan dhab ahaantii cabbirnaa dhererka heerka dareeraha: Dhererka heerka dareeraha H = (P1-PX) / (ρ * g) + D / (ρ * g);
Fiiro gaar ah: PX waa in la cabbiro qiimaha cadaadiska ee dhinaca cadaadiska hooseeya;
P1 waa qiimaha cadaadiska ee lagu cabbirayo dhinaca cadaadiska sare;

Taxadir Rakibaadda
Ku rakibida flange-ka kali ah ayaa muhiim ah
1. Marka gudbiyaha xuubka go'doominta ee taangiyada furan loo isticmaalo cabbirka heerka dareeraha ee taangiyada dareeraha ah ee furan, dhinaca L ee dhinaca cadaadiska hoose waa inuu u furnaa jawiga.
2. Taangiga dareeraha ah ee xiran, tuubada hagta cadaadiska ee hagida cadaadiska taangiga dareeraha waa in ay ku dhejisaa dhinaca L ee dhinaca cadaadiska hoose.Waxay qeexaysaa cadaadiska tixraaca ee haanta.Intaa waxaa dheer, had iyo jeer fur fur-fure-biyoodka dhinaca L si aad u daadiso kondensate ee qolka dhinaca L, haddii kale waxay keeni doontaa khaladaadka cabbirka heerka dareeraha.
3. Gudbiyaha waxaa lagu xiri karaa rakibaadda flange ee dhinaca cadaadiska sare sida ku cad Jaantus 1-3.Garaashka dhinaca taangiga ahi guud ahaan waa garab la dhaqaajin karo, kaas oo wakhtigaas go’an oo lagu alxan karo hal gujin, taas oo ku habboon rakibida goobta.
Jaantuska 1-3 Tusaalaha rakibaadda ee gudbiyaha heerka dareeraha nooca flange
1) Marka la cabbirayo heerka dareeraha ee haanta dareeraha, heerka dareeraha ugu hooseeya (eber dhibic) waa in la dejiyaa fogaan ah 50mm ama ka badan oo ka mid ah bartamaha dhinaca cadaadiska sare ee diaphragm.Jaantuska 1-4:
Jaantuska 1-4 Tusaalaha rakibaadda haanta dareeraha ah
2) Ku rakib diaphragm flange dhinaca sare (H) iyo dhinaca hoose (L) ee taangiga sida ku cad calaamadda gudbiyaha iyo dareenka.
3) Si loo yareeyo saameynta kala duwanaanshaha heerkulka deegaanka, tuubooyinka capillary ee dhinaca cadaadiska sare waa la isku xiri karaa oo la hagaajin karaa si looga hortago saameynta dabaysha iyo gariirka (tuubooyinka xididada qaybta dheer ee qaybta dheer waa in la isku rogaa. oo go'an).
4) Inta lagu jiro hawlgalka rakibidda, isku day inaadan cadaadiska hoos u dhigista dareeraha daboolka ah ku dhejin shaabadda diaphragm inta suurtogalka ah.
5).
6) Dabcan, haddii aan lagu rakibin karin 600mm ama in ka badan oo ka hooseeya qaybta rakibaadda ee qaybta shaabadda diaphragm flange sababtoo ah xaddidaadda shuruudaha rakibidda.Ama marka jirka gudbiyaha lagu rakibi karo oo keliya ka sarreeya qaybta rakibaadda shaabadda flange sababo la taaban karo awgeed, booska rakibaadda waa inuu buuxiyaa qaacidada xisaabinta ee soo socota.
1) h: dhererka u dhexeeya qaybta rakibaadda diaphragm flange fog iyo jidhka gudbiyaha (mm);
① Marka h≤0, gudbiyaha jirka waa in lagu rakibaa ka sarraysa h (mm) oo ka hooseysa qaybta rakibaadda shaabada diaphragm flange.
②Marka h>0, jidhka gudbiyaha waa in lagu rakibaa ka hooseeya h (mm) oo ka sarreeya qaybta rakibaadda diaphragm flange.
2) P: Cadaadiska gudaha ee haanta dareeraha ah (Pa abs);
3) P0: Xadka hoose ee cadaadiska uu isticmaalo jirka gudbiyaha;
