Centrifugal twj tso kua mis
Centrifugal twj tso kua mis qauv, ntau yam, specifications, thiab lawv cov variants yog cov feem ntau siv nyob rau hauv ua liaj ua teb twj. Cov twj centrifugal muaj xws li ib zaug -theem ib zaug suction centrifugal twj, ib zaug -theem ob chav suction centrifugal twj, multi-theem centrifugal twj, tus kheej-priming centrifugal twj, fais fab twj tso kua mis, thiab diesel cav twj, nyob ntawm seb lub impeller cov twj tso kua mis, seb cov dej ntws mus rau hauv lub cev muaj pes tsawg leeg. suction, thiab qhov loj thiab ntau yam kev txhawb zog.
1. Ib theem ib zaug suction centrifugal twj tso kua mis
Cov qauv twj tso kua mis qub suav nrog BA thiab B ib zaug -theem ib zaug suction centrifugal twj. Hauv xyoo 1980, Tuam Tshoj tau hloov kho thiab tsim cov khoom siv twj tso kua mis centrifugal raws li cov qauv thoob ntiaj teb thiab qhov xwm txheej tiag tiag ntawm kev siv dej thiab cov tshuab ua kua, thiab tsim IB thiab IQ ib zaug -theem centrifugal twj series cov khoom, uas tau teev raws li lub teb chaws cov qauv kev lag luam thiab cov qauv kev lag luam.
Ib theem ib zaug suction centrifugal twj tso kua mis, dej nkag mus rau hauv lub impeller los ntawm ib sab nyob rau hauv lub axial kev taw qhia, thiab tsuas muaj ib tug impeller, yog li ntawd nws yog hu ua ib tug -theem ib zaug suction centrifugal twj. Nws cov yam ntxwv yog tias piv nrog cov twj tso kua mis sib xyaw thiab cov twj tso kua mis axial, nws muaj lub taub hau siab dua, tus nqi qis dua, cov qauv yooj yim dua, thiab siv tau yooj yim.
IQ ib zaug -theem ib zaug suction centrifugal twj tso kua mis (tseem hu ua lub teeb yuag centrifugal twj tso kua mis) yog tsim los ua kom tau raws li qhov yuav tsum tau ua ntawm cov qauv yooj yim, lub teeb yuag, tus nqi qis, kev ua haujlwm zoo, thiab kev sib txuam yooj yim rau cov neeg siv raws li Tuam Tshoj lub teb chaws tej yam kev mob. Muaj tag nrho ntawm 84 cov khoom, muab faib ua 3 derivative series thiab 413 specifications thiab qauv.
(1) Qhov kev ua tau zoo ntawm lub twj tso kua mis yog 50-200 millimeters inch, nrog tus nqi ntws ntawm 12.5-400 cubic meters ib teev twg thiab lub taub hau ntawm 8-125 meters. Lub zog txhawb nqa suav nrog lub tshuab hluav taws xob sib txuas ncaj qha, siv txoj hlua txuas, thiab lub tshuab hluav taws xob ncaj qha kev sib txuas, nrog lub zog ntawm 1.1-110 kilowatts thiab ceev ntawm 1450-2900 revolutions ib feeb.
(2) Hom qauv ntawm lub teeb yuag thiab me me - loj centrifugal twj tso kua mis yog ib qho axial suction ib zaug -theem ib zaug suction suspension centrifugal twj. Lub twj tso kua mis lub cev muaj lub qhov rooj qhib tom qab, thiab lub qhov hluav taws xob nyob hauv nruab nrab ntawm sab saud. Lub nraub qaum yog nias haum, thiab lub cev bearing yog txuas ncaj qha mus rau lub twj tso kua mis lub cev. Lub twj tso kua mis taw yog nyob hauv qab lub twj tso kua mis lub cev, thiab cov kabmob yog lubricated nrog butter. Lub foob foob tau muab faib ua peb hom: mos ntim, tshuab foob, thiab roj hmab roj foob. Cov impellers tau kaw tag nrho, thiab kev sib kis tau muab faib ua ob hom: kev sib txuas sib txuas thiab siv txoj hlua sib kis. Pump impeller rotation: Thaum saib los ntawm lub twj tso kua mis inlet kev taw qhia, lub impeller rotation yog clockwise. Thaum lub twj tso kua mis txuas ncaj qha mus rau lub cav diesel rau kev sib kis, nws yog counterclockwise. Lub qhov hluav taws xob lub twj tso kua mis tuaj yeem nruab nrog lub twj tso kua mis phau ntawv, uas tuaj yeem tshem tawm lub valve hauv qab, txo qis hydraulic poob, thiab ua kom lub twj tso kua mis rau nws tus kheej nqus.
2. Ib theem ob chav nqus centrifugal twj tso kua mis
Nws yog ib qho -theem ob chav suction centrifugal twj uas tau txais dej los ntawm ob sab ntawm lub impeller. Raws li lub twj tso kua mis thiab lub cev tau sib sau ua ke siv kab rov tav seams, nws tseem hu ua kab rov tav qhib hom centrifugal twj tso kua mis. Piv nrog rau ib zaug -theem ib zaug suction centrifugal twj, nws muaj kev ua tau zoo dua, qhov ntws loj dua, thiab lub taub hau siab dua. Tab sis nws muaj lub ntim loj thiab yog qhov loj, feem ntau yog siv rau kev ua haujlwm ruaj khov. Haum rau thaj chaw dej hauv toj roob hauv pes thiab toj siab, nrog rau cov chaw tsim khoom, mines, dej hauv nroog thiab cov dej ntws.
Muaj ntau yam qauv ntawm ib zaug -theem ob chav nqus centrifugal twj, suav nrog S- hom, Sh hom, SA hom, thiab SLA hom. Qhov sib txawv ntawm S- hom thiab Sh hom yog tias, los ntawm kev tsav tsheb kawg, S- hom twj rotates clockwise, thaum Sh hom twj rotate counterclockwise. SLA hom yog ntsug ib zaug -theem ob chav nqus centrifugal twj tso kua mis.
Qhov kev ua tau zoo ntawm S- hom twj tso kua mis yog ntws tus nqi ntawm 160-18000 cubic meters ib teev, lub taub hau ntawm 12-125 meters, inlet txoj kab uas hla ntawm 150-1400 millimeters, thiab rotation ceev ntawm 2950, 1450, 970, 730, 585, 600 revolutions ib feeb
(1) Qhov kev ua tau zoo ntawm D- hom twj tso kua mis yog 6.3-720 cubic meters ib teev, nrog lub taub hau ntawm 16-600 meters thiab inlet diameters ntawm 50, 75, 100, 125, 150, thiab 200 millimeters. 50-125 millimeter twj tso kua mis qauv muaj kev kub ceev ntawm 2950 revolutions ib feeb, thaum lub 150-200 millimeter twj tso kua mis qauv muaj ib tug ceev ntawm 1480 revolutions ib feeb.
(2) Lub D-hom multi-stage centrifugal twj tso kua mis yog kab rov tav multi-theem (2-}12 theem) nrog rau ib qho suction impeller thiab segmented twj tso kua mis lub cev. Thaum thawj theem impeller yog ob chav nqus, nws yog sawv cev los ntawm DS. Thaum ob qhov ceev tau teev tseg ib txhij, qhov ceev qis yog sawv cev los ntawm DA. Rau ntau theem centrifugal twj siv rau boiler feedwater, nws yog sawv cev los ntawm DG.
3. Self priming centrifugal twj tso kua mis
Tus kheej- lub twj tso kua mis yog ib qho -theem ib zaug suction centrifugal twj tso kua mis uas tsim nws tus kheej- cov nyhuv priming los ntawm cov qauv tshwj xeeb ntawm lub twj tso kua mis nws tus kheej, hu ua tus kheej -priming centrifugal twj. Piv nrog rau cov twj centrifugal zoo tib yam, muaj qhov sib txawv tseem ceeb hauv lub twj tso kua mis lub cev qauv: ua ntej, qhov chaw nkag ntawm lub twj tso kua mis tau tsa, thiab qee zaum lub tshuab nqus tsev kuj tau teeb tsa; Qhov thib ob, lub tshuab hluav taws xob sib cais yog nruab rau ntawm qhov hluav taws xob sab.
Lub twj tso kua mis tus kheej -priming yog ib hom twj tso kua mis uas muaj tus kheej - cov khoom siv priming txuas nrog lub twj tso kua mis, xws li lub twj tso kua mis vortex, lub nplhaib dej nqus twj, lub twj tso kua mis dav hlau, thiab lub twj tso kua mis.
Piv nrog cov twj centrifugal zoo tib yam, tus kheej- cov twj tso kua mis muaj cov qauv compact thiab kev ua haujlwm yooj yim, uas tsis tsuas yog txuag cov teeb meem ntawm cov dej ntau ua ntej pib, tab sis kuj tshem tawm qhov qis qis ntawm cov yeeb nkab inlet, txo cov inlet tsis kam, thiab ua kom lub twj tso kua mis cov dej tso tawm. Txawm li cas los xij, piv nrog cov twj tso kua mis centrifugal zoo tib yam, qhov ua tau zoo yog 3% mus rau 5% qis dua. Cov twj tso kua mis tus kheej feem ntau yog siv rau hauv lub teeb thiab me me sprinkler irrigation units thiab pipeline irrigation units.
