2024-09-14
bamka centrifugalWaa mashiinka dareeraha caadiga ah kaas oo mabda'a shaqadu uu ku salaysan yahay xoogga centrifugal.
Kuwa soo socda waabamka centrifugalXogta faahfaahsan iyo sharraxaadda sida ay u shaqeyso:
1.qaab dhismeedka aasaasiga ah
1.1 Jirka bamka
- Qalab: birta shubka ah, birta aan lahayn, naxaasta, iwm.
- naqshadeynta: Sida caadiga ah qaabka volute, loo isticmaalo in lagu ururiyo laguna hago socodka dareeraha.
1.2 Impeller
- Qalab: birta shubka ah, birta aan lahayn, naxaasta, iwm.
- naqshadeynta: Impeller waabamka centrifugalQaybaha asaasiga ah waxaa badanaa loo qaybiyaa saddex nooc: xiran, badh-furan iyo furan.
- Tirada caleemaha: Caadi ahaan 5-12 kiniin, taas oo ku xidhan naqshadaynta bamka iyo codsiga.
1.3 dhidibka
- Qalab: bir xoog badan ama bir ah.
- ShaqadaKu xidh matoorka iyo wiishka si aad u gudbiso awooda.
1.4 Qalabka wax lagu xiro
- nooca: shaabadda makaanikada ama shaabadda baakadaha.
- ShaqadaKa hortagga dareeraha dareeraha ah.
1.5 Gawaarida
- nooca: sida wax ku duuban ama simbiriirixan.
- Shaqada: Waxay taageertaa usheeda dhexe waxayna yaraynaysaa khilaaf.
2.Mabda'a shaqada
2.1 Dheecaanku wuxuu galaa jidhka bamka
- Habka gelitaanka biyahaDheecaanku wuxuu ka soo galaa jidhka bamka isagoo sii mara tuubada soo galitaanka, badanaa wuxuu soo maraa tuubada nuugista iyo valve nuugista.
- Dhexroorka gelitaanka biyaha: Lagu go'aamiyay iyadoo lagu saleynayo qeexida bamka iyo shuruudaha naqshadeynta.
2.2 Impeller wuxuu dedejiyaa dareeraha
- Xawaaraha impeller: Caadi ahaan 1450 RPM ama 2900 RPM (kacaanka daqiiqadii), taas oo ku xidhan naqshadaynta bamka iyo codsiga.
- xoogga centrifugal: impeller-ku wuxuu ku wareegaa xawaaraha sare ee uu wado matoorku, dareerahana waxaa dardargeliyay xooga centrifugal.
2.3 Dareeraha ayaa ku qulqulaya bannaanka jidhka bamka
- Naqshadaynta orodyahankaDareeraha la dedejiyey ayaa u soo qulqulaya dibadda iyada oo la raacayo jidka qulqulka ee impeller oo gala qaybta codka ee jidhka bamka.
- Naqshad mug lehNaqshadeynta cod-bixinta waxay ka caawisaa tamarta kinetic ee dareeraha u beddelo tamarta cadaadiska.
2.4 Dareere laga soo daayay jidhka bamka
- Habka biyo-baxa: Dareeraha waxaa lagu sii dareemaa qulqulka waxaana loo beddelaa tamarta cadaadiska, waxaana laga sii daayaa bamka iyada oo loo marayo tuubada biyaha.
- Dhexroorka bannaanka: Lagu go'aamiyay iyadoo lagu saleynayo qeexida bamka iyo shuruudaha naqshadeynta.
3.habka beddelka tamarta
3.1 Beddelka tamarta Kinetic
- Dardargelinta impellerDareeraha waxa uu helayaa tamar kinetic ah oo hoos timaada ficilka impeller, xawaarhiisuna wuu kordhaa.
- Qaaciddada tamarta Kinetic: ( E_k = \ frac {1}{2} mv^2 )
- (E_k): tamarta kinetic
- (m): Cufka dareeraha ah
- (v): xawaaraha dareeraha
3.2 Beddelka tamarta cadaadiska
- Hoos u dhigista muggaDareeraha ayaa hoos u dhiga codka, tamarta kinetic-ka waxaa loo beddelaa tamar cadaadis.
- Bernoulli isla'egta( P + \frac{1}{2} \rho v^2 + \rho gh = \ text{constant} )
- (P): Cadaadis
- ( \rho): cufnaanta dareeraha
- (v): xawaaraha dareeraha
- (g): dardargelinta cufisjiidka
- (h): joog
4.Halbeegyada waxqabadka
4.1 Socodka (Q)
- qeexid:bamka centrifugalQadarka dareeraha la keenay halbeegkiiba.
- unug: mitir cubic saacaddii (m3/h) ama litir ilbiriqsikii (L/s).
- baaxadda: Caadi ahaan 10-5000 m3/h, taasoo ku xidhan nooca bamka iyo codsiga.
4.2 Kor u qaadis (H)
- qeexid:bamka centrifugalAwood u leh inuu kor u qaado dhererka dareeraha.
- unug: Mitir (m).
- baaxadda: Sida caadiga ah 10-150 mitir, taas oo ku xidhan nooca bamka iyo codsiga.
4.3 Awood (P)
- qeexid:bamka centrifugalAwoodda matoorka.
- unug: kilowatt (kW).
- formula xisaabinta:( P = \ frac {Q \ times H}{102 \ times \ eta} )
- (Q): heerka socodka (m3/h)
- (H): Kor u qaadis (m)
- ( \eta): waxtarka bamka (sida caadiga ah 0.6-0.8)
4.4 Waxtarka (η)
- qeexid: Waxtarka beddelka tamarta ee bamka.
- unug:boqolkiiba(%).
- baaxadda: Sida caadiga ah 60% -85%, taas oo ku xidhan naqshadaynta bamka iyo codsiga.
5.Dhacdooyinka codsiga
5.1 Biyo-gelinta dawladda hoose

- socodkaSida caadiga ah 100-1500 m3/h
- Kor u qaad: Caadiyan 10-50 mitir.
5.4 Dhismaha biyaha
- isticmaal: Waxaa loo isticmaalaa nidaamyada biyaha ee dhismayaasha dhaadheer.
