Mabda'a shaqada ee bamka centrifugal

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.
