Dab tsi yog Qhov Feem Ntau Cov Centrifugal Pump?

Dab tsi yog lub twj tso kua mis centrifugal tshaj plaws?

Cov twj centrifugal tau siv dav hauv ntau qhov kev lag luam thiab kev siv vim lawv cov qauv yooj yim, kev ua tau zoo, thiab ntau yam. Lawv ua haujlwm los ntawm kev hloov pauv lub zog los ntawm lub tshuab hluav taws xob lossis lub cav mus rau hauv lub zog kinetic uas tau xa mus rau cov kua dej uas tau muab tso rau. Cov kua dej no nkag mus rau hauv lub twj tso kua mis los ntawm qhov chaw ntawm lub impeller rotating thiab yog propelled tawm sab nraud ntawm lub twj tso kua mis. Tab sis dab tsi yog hom twj centrifugal tshaj plaws? Cia peb tshawb nrhiav lo lus nug no thiab delve rau hauv lub ntiaj teb ntawm cov twj centrifugal.

Taw qhia rau Centrifugal Pumps

Cov twj centrifugal tau muab faib ua ntau hom raws li cov yam ntxwv xws li lawv cov qauv tsim, tus naj npawb ntawm impellers, thiab qhov xwm txheej ntawm cov kua dej uas tau tso tawm. Txawm li cas los xij, ib hom tshwj xeeb sawv tawm raws li feem ntau thiab siv dav hauv kev lag luam sib txawv - ib-theem kawg-suction centrifugal twj.

Single-Stage End-Suction Centrifugal Pump

Ib-theem kawg-suction centrifugal twj tso kua mis yog qhov kev xaiv nrov vim nws txoj kev yooj yim, kev ntseeg tau, thiab kev saib xyuas yooj yim. Nws feem ntau yog siv rau cov ntawv thov uas xav tau cov nqi qis qis thiab qis qis. Hom twj tso kua mis no muaj ib lub impeller mounted ntawm ib tug rotating ncej. Lub impeller yog nyob rau hauv ib lub volute casing uas coj cov dej ntws mus rau lub twj tso kua mis qhov hluav taws xob.

Tsim thiab ua haujlwm

Kev tsim ntawm ib-theem kawg-suction centrifugal twj tso kua mis yog qhov ncaj nraim. Nws muaj cov ntsiab lus hauv qab no:

1. Impeller: Lub impeller yog ib qho kev sib hloov nrog cov hniav nkhaus uas hloov lub zog rau cov kua dej. Nws feem ntau yog ua los ntawm cov hlau los yog yas thiab tsim cov centrifugal quab yuam, thawb cov kua dej ntawm lub qhov hluav taws xob.

2. Volute Casing: Lub volute casing yog ib lub tsev nyob ruaj khov uas sau cov kua dej los ntawm lub impeller thiab hloov lub siab ceev kinetic zog mus rau lub zog siab. Cov duab ntawm lub volute casing yog ib qho tseem ceeb hauv kev ua kom cov dej ntws zoo thiab ua haujlwm tau zoo.

3. Ncej thiab Bearings: Lub impeller yog mounted ntawm ib tug ncej, uas yog txuas nrog lub cev muaj zog los yog lub cav uas muab lub zog tig. Cov ncej yog txhawb nqa los ntawm cov kabmob kom txo qis kev sib txhuam thiab ua kom cov haujlwm du.

4. Mechanical Seal lossis Packing: Txhawm rau tiv thaiv kom tsis txhob muaj qhov sib txawv ntawm cov ncej tig thiab qhov chaw nyob ruaj khov, siv lub tshuab foob lossis ntim khoom. Mechanical seals muab kev sib khi zoo dua thiab yuav tsum muaj kev saib xyuas tsawg dua piv rau cov khoom ntim ib txwm muaj.

5. Inlet thiab qhov hluav taws xob: Lub twj tso kua mis muaj qhov nkag los ntawm cov kua dej nkag mus thiab lub qhov hluav taws xob qhov hluav taws xob uas nws tawm mus. Qhov loj thiab kev teeb tsa ntawm cov chaw nres nkoj no yuav txawv nyob ntawm daim ntawv thov thiab cov kev xav tau ntws.

Kev ua haujlwm ntawm ib theem kawg-suction centrifugal twj tso kua mis yog qhov yooj yim. Thaum lub cev muaj zog lossis lub cav pib, nws tig lub impeller, tsim kom muaj qhov chaw qis qis ntawm qhov chaw. Qhov no rub cov kua rau hauv lub twj tso kua mis los ntawm lub inlet. Raws li lub impeller spin, nws imparts kinetic zog rau cov kua, thawb nws tawm sab nraud ntawm lub volute casing. Cov kua tau nce nrawm thiab siab thaum nws dhau los ntawm lub volute casing, nws thiaj li ncav cuag lub qhov hluav taws xob.

Daim ntawv thov

Ib-theem kawg-suction centrifugal twj pom daim ntawv thov thoob plaws ntau yam kev lag luam thiab cov txheej txheem vim lawv ntau yam thiab ua haujlwm tau zoo. Qee cov ntawv thov siv xws li:
