Markii Zonel Filtech ay ka caawiso macaamiisha si ay u horumariyaan boodhka ururintooda, qaarkood ayaa laga cawday in nidaamyada nadiifintaguri filter bacSi fiican uma shaqeeyo xitaa haddii ay isticmaalaan tuubada hawo-qaadka ee tuubada hawada afuufaysa, sidoo kale leh venturi, iyo sidoo kale cadaadiska saxda ah ee hawada ciriiriga ah, markaa ma heli karaan xalka hagaajinta shaqooyinka nadiifinta.

Ka dib markii la falanqeeyay nidaamkooda nadiifinta, injineerada Zonel ayaa la ogaaday sababta ugu weyn ee ah in masaafada u dhexeysa tuubahooda hawo-mareenka iyo xaashida tuubada boorsada aysan sax ahayn. Haddii masaafada aad u weyn tahay, hawadu waxay ku afuufi kartaa qaar ka mid ah xaashida tuubada boorsada halkii ay gelin lahayd bacaha shaandhada; Taas beddelkeeda, haddii ay aad u yar tahay, hawada la cadaadiyo uma horseedi karto hawo ku filan bannaanka bacaha shaandhada, saamaynta nadiifinta ayaa hubaal ah in aanay wanaagsanayn.

Laakiin sida loo qeexo masaafadan (H1 sawirka soo socda)?

１.Tallaabada koowaad, waxaad u baahan tahay inaad qeexdo celceliska qiimaha Øp ee sawirka.
Sida caadiga ah, waxaan ku xisaabineynaa Øp qaacidada soo socota:
Øp=(C*D^2/n) ^1/2
C=Coefficient, sida caadiga ah dooro 50%~65%.
D=dhexroorka daloolka garaaca wadnaha jet, sida caadiga ah waxay la mid tahay tuubooyinka hawada afuufaya.
n=lambarka bacda shaandhada safkiiba (ku nadiifinta isla waalka jet garaaca wadnaha)
Sida caadiga ah, C waxaan dooraneynaa 0.55.
Inta badan, tuubada hawo-mareenka dhexroorku waa 2 ~ 3 jeer ee Øp.

 

2. Qeex dhererka tuubada hawo hogaaminaysa.
Dhuumaha hawo hawo sida caadiga ah isticmaal qaacidooyinka soo socda:
L=Ck* Øp/K
Ck=coefficient, sida caadiga ah dooro 0.2 ~ 0.25
K=waa isku xidhka qaska jet, cylindrical door 0.076.
ie L= ku dhawaad ​​0.2* Øp/0.076=2.65 Øp

 

Aad ayey u fududahay in la helo tg shahaadada = (1/2 Øb)/H2
tg a degree = 3.4K=0.272 (waxaa loo daweyn karaa si joogto ah)
Markaa shahaado dooro 15 digrii.

 

Tusaale ahaan:
Haddii aad dooratid 3 ″ immersed pulse jet valve, tuubada hogaaminaysa d=30mm, dhexroorka bacda filterku waa 160mm, sida loo helo H1.
Jawaab:
Sida iska cad, H1=H2-L
Markaa waa inaan qeexno H2 iyo L.

tg shahaadada = (1/2 Øb)/H2=3.4K=0.272
ie H2=1.838 Øb

Øb = 160mm
Markaa H2=294 mm

2
Natiijadii hore, L = 2.65 Øp, sidaas darteed L = 2.65 * 15 = 40 mm
Markaa H1=294-40=254mm.

 

Qp, guud ahaan celceliska xogta waxaa loo dooran karaa sida soo socota:
Cabbirka jet-ka garaaca wadnaha ---- Qp
3/4" ----5 ~ 7mm
1" ---- 6 ~ 8mm
1 1/2" ----7 ~ 9mm
2”----8-11mm
2 1/2" ----9 ~ 14mm
3”----14-18mm
4 "----16-22mm

 

Sida caadiga ah, marka naqshadda Qp loo qaybin doono kooxaha 3 ~ 4, oo u dhow valve jet valve, xajmiga furan ee weyn, iyo koox si ay u ururiyaan kala duwanaanshaha dhexroorka ee ku saabsan 1mm.
