Dab tsi yog 3 Hom Centrifugal Pumps?

Dab tsi yog 3 hom centrifugal twj tso kua mis?

Cov twj centrifugal tau siv dav hauv ntau qhov kev lag luam rau kev hloov cov kua dej, muab lub siab, thiab tswj cov dej ntws. Lawv feem ntau siv rau hauv cov ntawv thov xws li cov khoom siv dej, kev siv dej, kev kho dej khib nyiab, tshuaj lom neeg kev lag luam, roj refineries, thiab ntau ntxiv. Hauv tsab xov xwm no, peb yuav tshawb txog peb yam sib txawv ntawm cov twj centrifugal, lawv cov qauv tsim, thiab lawv cov kev siv.

Centrifugal Pump Tsim thiab Cov Cai Ua Haujlwm
Cov twj centrifugal muaj ntau yam tseem ceeb, suav nrog lub impeller, lub casing, thiab lub cev muaj zog. Lub impeller yog ib qho rotating tivthaiv uas muaj cov hniav nkhaus, lub luag hauj lwm rau imparting zog rau cov kua. Lub casing yog tsim los kaw lub impeller thiab coj cov dej ntws mus rau hauv ib qho kev taw qhia tshwj xeeb. Lub cev muaj zog muab lub zog xav tau los tsav lub impeller, feem ntau yog los ntawm lub tog raj kheej.

Cov twj centrifugal ua haujlwm raws li lub hauv paus ntsiab lus ntawm lub zog centrifugal. Thaum lub impeller tig, cov kua dej tawm sab nraud vim lub zog centrifugal tsim los ntawm cov hniav tig. Cov kua dej tawm sab nraud no tsim kom muaj qhov tsis tshua muaj siab nyob ze ntawm qhov chaw ntawm lub impeller, uas tso cai rau cov kua ntau ntxiv rau hauv lub twj tso kua mis. Raws li qhov tshwm sim, cov kua dej tas mus li raug tsim, thiab nws tawm ntawm qhov siab dua los ntawm qhov hluav taws xob ntawm lub twj tso kua mis.

1. End-Suction Centrifugal Pump
Qhov kawg-suction centrifugal twj tso kua mis yog ib qho ntawm feem ntau hom siv nyob rau hauv ntau yam lag luam. Raws li lub npe qhia, cov kua dej yog nqus los ntawm ib qho kawg ntawm lub twj tso kua mis thiab tawm ntawm qhov kawg. Lub twj tso kua mis no nyiam rau nws qhov yooj yim, compact tsim, thiab yooj yim ntawm kev txij nkawm. Qhov kawg-suction twj yog feem ntau horizontally mounted nrog ib tug kab rov tav ncej, ua rau nws yooj yim rau nruab thiab khiav lag luam.

Qhov kawg-suction twj tso kua mis yog tsim rau cov ntawv thov uas yuav tsum tau nruab nrab mus rau high flow rates thiab kuj qis mus rau nruab nrab tawm pressures. Nws yog feem ntau siv hauv cov kav dej, HVAC systems, thiab cov ntawv thov kev lag luam. Hom twj tso kua mis no kuj muaj nyob rau hauv ntau yam ntaub ntawv los lis ntau hom kua, nrog rau cov kua corrosive.

2. Split Case Centrifugal Pump
Cov ntaub ntawv sib cais centrifugal twj tso kua mis yog lwm yam nrov ntawm centrifugal twj tso kua mis, tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum tau muaj tus nqi siab thiab siab tawm siab. Lub twj tso kua mis no yog hu ua "split case" vim tias nws cov casing yog horizontally faib ua ob halves kom yooj yim txij nkawm thiab tshuaj xyuas cov khoom sab hauv.

Lub twj tso kua mis sib cais muaj ob lub impellers zoo tib yam mounted ntawm ib qho kev sib txuas, tig mus rau ib leeg. Cov kua dej nkag mus rau hauv lub twj tso kua mis los ntawm kev nqus inlet thiab muab faib sib npaug ntawm ob lub impellers. Cov impellers ces tsim lub zog centrifugal, muab lub zog rau cov kua dej, thiab thaum kawg, cov kua tawm tawm los ntawm qhov hluav taws xob ntau.

Vim nws cov qauv tsim, cov ntaub ntawv sib cais lub twj tso kua mis tuaj yeem tswj cov dej ntws loj thiab kev kub siab ua haujlwm tau zoo. Nws yog feem ntau siv hauv cov chaw kho dej, chaw tsim hluav taws xob, hluav taws xob tiv thaiv hluav taws xob, thiab cov kav dej. Lub twj tso kua mis cais kuj tseem paub txog nws txoj kev ntseeg siab, kev ua haujlwm ntev, thiab kev saib xyuas yooj yim.

3. Vertical Turbine Centrifugal Pump
Vertical turbine centrifugal twj tso kua mis yog tsim tshwj xeeb rau cov ntawv thov uas yuav tsum tau siv cov kua dej los ntawm qhov dej tob los yog cov reservoirs. Hom twj tso kua mis no yog vertically mounted thiab ua hauj lwm submerged nyob rau hauv cov kua uas yog pumped. Nws muaj ntau theem los yog impellers stacked vertically raws lub twj tso kua mis ncej.

Nyob rau hauv lub ntsug turbine twj tso kua mis, txhua lub impeller muab lub zog rau cov kua dej, thiab cov kua dej yog coj mus rau theem tom ntej los ntawm diffuser. Cov txheej txheem no txuas ntxiv mus txog thaum cov kua dej nce mus txog saum lub twj tso kua mis, qhov chaw uas nws tawm los ntawm lub qhov hluav taws xob ntsug. Vertical turbine twj tso kua mis muaj peev xwm tswj tau qhov siab tawm qhov siab tau zoo thiab tsim nyog rau kev siv dej ntau ntawm qhov tob.

Vertical turbine twj tso kua mis feem ntau yog siv rau hauv kev ua liaj ua teb irrigation, municipal water supply systems, industrial water supply, and in applications where a deep water source yuav tsum tau nkag mus. Nws muaj cov txiaj ntsig xws li kev tsim qhov chaw txuag, kev teeb tsa yooj yim, thiab muaj peev xwm tso dej los ntawm qhov tob tob.

Xaus
Centrifugal twj tso kua mis ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam los ntawm kev muab lub zog tsim nyog thiab ntws rau cov kua hloov pauv. Peb hom tau tham nyob rau hauv tsab xov xwm no, uas yog qhov kawg-suction centrifugal twj tso kua mis, cais rooj plaub centrifugal twj tso kua mis, thiab ntsug turbine centrifugal twj tso kua mis, muaj cov qauv tsim sib txawv thiab haum rau cov kev siv sib txawv.

Qhov kawg-suction twj tso kua mis yog dav siv rau kev siv dav dav, thaum lub twj tso kua mis sib cais yog qhov xav tau rau kev ua haujlwm siab thiab siab-siab. Vertical turbine twj tso kua mis yog tsim tshwj xeeb rau kev tso dej los ntawm qhov tob tob los yog cov reservoirs. Kev nkag siab txog ntau hom twj centrifugal thiab lawv cov ntawv thov tshwj xeeb tuaj yeem pab xaiv lub twj tso kua mis tsim nyog tshaj plaws rau ib qho kev lag luam lossis qhov project.
