Centrifugal twj tso kua mis nrog qhov chaw nqus dej - Lub twj tso kua mis centrifugal yooj yim siv

I. Taw qhia txog Centrifugal Suction Pumps
Qhov kawg suction centrifugal twj tso kua mis yog ib hom twj tso kua mis centrifugal, tseem hu ua qhov kawg suction twj. Qhov kawg suction centrifugal twj tso kua mis txais cov qauv nqus rov qab thiab tsis tas yuav tshem lub twj tso kua mis los nruab thiab hloov lub impeller, lub ntsiab ncej thiab bearings. Cov qauv ruaj khov tuaj yeem txo qhov tsis zoo thiab deformation ntawm cov kav dej mus rau qhov loj tshaj plaws.
Technical parameters yog raws li nram no: Qhov siab tshaj plaws ntws: 150 cubic meters ib teev twg; Lub taub hau siab tshaj plaws: 100 meters; Ua kua kub ntau: 0 ° C mus rau 100 ° C; Ua haujlwm siab tshaj plaws: 1.0 megapascal.

II. Cov yam ntxwv ntawm qhov kawg suction centrifugal twj tso kua mis
Nws nta ib qho yooj yim txij nkawm-rov qab- thawb hom qauv. Yog tsis muaj qhov yuav tsum tau dismantle lub inlet thiab qhov hluav taws xob pipelines ntawm lub system, lub rotating Cheebtsam yuav muab tau yooj yim tshem tawm rau txij nkawm.
2. Nyob rau sab saum toj yog qhov nruab nrab qhov hluav taws xob. Lub twj tso kua mis yog kev txhawb nqa los ntawm ko taw daim hlau, uas tuaj yeem tiv thaiv qhov tsis zoo thiab deformation tshwm sim los ntawm cov raj xa dej.
3. Nws txais yuav cov qauv dej ntws patented los ntawm 荏原, uas ua rau muaj kev ua haujlwm siab dua, qhov dav dav thiab cov nqi khiav lag luam qis dua.
4. Lub impeller thiab sealing nplhaib yog ua los ntawm cov khoom siv tooj liab, uas tiv taus xeb thiab hnav, yog li ua rau lub neej ua haujlwm ntev.
5. Cov bearings, mechanical seals, thiab motors raug xaiv los ntawm lub ntiaj teb no renowned kev lag luam hom manufacturers, yog li xyuas kom meej tias tag nrho cov kev ua tau zoo ntawm lub tshuab yog ruaj khov thiab txhim khu kev qha.
III. Txoj Cai Ua Haujlwm ntawm Qhov Kawg -Suction Centrifugal Pump
Thaum lub tshuab nqus tsev nqus tau pib, lub twj tso kua mis ncej tsav lub impeller kom tig ntawm kev kub ceev ua ke. Qhov no yuam cov kua ua ntej - puv nruab nrab ntawm cov hniav kom tig. Nyob rau hauv qhov kev txiav txim ntawm inertial centrifugal quab yuam, cov kua txav radially los ntawm qhov chaw ntawm lub impeller mus rau lub periphery. Thaum cov txheej txheem ntws los ntawm lub impeller, cov kua tau txais lub zog, nrog rau nws cov siab zoo li qub nce thiab txaus tus nqi nce. Thaum cov kua tawm ntawm lub impeller thiab nkag mus rau hauv lub twj tso kua mis, vim qhov maj mam nthuav dav ntws hauv cov casing, qhov tshaj tawm txo qis. Qee lub zog kinetic hloov mus rau lub zog zoo li qub, thiab thaum kawg ntws tangentially rau hauv cov kav dej tawm. Yog li ntawd, lub volute twj tso kua mis casing tsis tsuas yog pab raws li ib tug tivthaiv rau sau cov kua tawm ntawm lub impeller, tab sis kuj ua raws li ib tug ntaus ntawv rau lub zog hloov dua siab tshiab. Nyob rau tib lub sij hawm raws li cov kua yog ejected radially los ntawm qhov chaw ntawm lub impeller mus rau lub periphery, ib tug tsawg - cheeb tsam siab nyob rau hauv nruab nrab ntawm lub impeller. Nyob rau hauv qhov kev txiav txim ntawm tag nrho cov muaj peev xwm sib txawv ntawm cov kua theem nyob rau hauv lub tank cia thiab qhov chaw ntawm lub impeller, cov kua yog kos rau hauv nruab nrab ntawm lub impeller. Los ntawm kev sib hloov tas mus li ntawm lub impeller, cov kua tau txuas ntxiv mus rau hauv thiab tawm mus. Lub zog txhua yam tau txais los ntawm cov kua hauv lub twj tso kua mis centrifugal thaum kawg tshwm sim raws li qhov nce hauv lub zog siab zoo li qub.

IV. Qhov sib txawv ntawm qhov kawg suction centrifugal twj tso kua mis thiab ob chav suction centrifugal twj tso kua mis
Qhov kawg suction twj tso kua mis tiag tiag yog ib lub twj tso kua mis. Qhov kawg suction centrifugal twj tso kua mis thiab ob chav suction centrifugal twj yog zoo sib xws, thiab lawv qhov zoo thiab qhov tsis zoo kuj zoo sib xws. Qhov sib txawv ntawm ob qho tib si yog cov dej nkag mus rau ib sab ntawm lub impeller nyob rau hauv cov ntaub ntawv ntawm qhov kawg suction (ib qho suction), thaum nyob rau hauv cov ntaub ntawv ntawm ob chav suction, dej yog qhia rau ob tog.
1. Cov yam ntxwv sib txawv
(1) Ob npaug -suction twj tso kua mis: Nws yog sib npaug rau ob qho tib si ib zaug -suction impellers ua haujlwm ib txhij. Nyob rau hauv tib lub impeller sab nraud txoj kab uas hla, tus nqi ntws tuaj yeem ua ob npaug; lub twj tso kua mis yog horizontally faib nyob rau hauv nruab nrab, ua rau kev soj ntsuam thiab txij nkawm yooj yim.
(2) Suction End Pump: Ib qho -theem suction centrifugal twj yog ib hom twj centrifugal yooj yim. Cov twj no feem ntau muaj qhov ntws me me thiab feem ntau yog cov twj me me - qhov loj me.
2. Cov khoom sib txawv
(1) Ob chav-suction twj tso kua mis: Ua los ntawm ob sab rov qab- rau- rov qab impellers, cov dej ntws tawm ntawm lub impellers converges mus rau hauv lub volute.
(2) Suction twj: Ib lub twj tso kua mis - theem txhais tau hais tias tsuas muaj ib lub impeller nyob rau hauv lub twj tso kua mis, thiab ib qho suction txhais tau hais tias cov dej los ntawm ib sab ntawm impeller.
3. Cov haujlwm sib txawv
(1) Lub twj tso kua mis ob -suction yog qhov tsim nyog rau kev xa cov kua dej ntau thiab ua haujlwm raws li qhov xav tau kev ua haujlwm ruaj khov. Thaum lub twj tso kua mis ntws tau siab heev, yog tias nws yog ib qho - suction twj, ces nws xav tau lub twj tso kua mis loj thiab qhov hluav taws xob txoj kab uas hla. Nyob rau tib lub sijhawm, kev sib hloov ceev tsis tuaj yeem siab dhau thiab yuav tsum ruaj khov ntawm ib ncig ntawm 1450 rpm. Yog tias siv ob -suction twj tso kua mis, qhov loj thiab qhov hnyav ntawm lub twj tso kua mis tuaj yeem txo qis, qhov kev sib hloov ceev tuaj yeem nce ntxiv, thiab kev ua haujlwm tau zoo tuaj yeem txhim kho.
(2) Kev tiv thaiv -cavitation muaj peev xwm ntawm ob - suction twj muaj zog dua li ntawm ib zaug - suction twj. Txij li qhov nruab nrab yog kos rau ntawm ob qho kawg ntawm lub impeller, hydraulic symmetry yog tsim. Raws li qhov tshwm sim, qhov sib npaug axial thrust nyhuv ntawm ob -suction twj zoo dua li ntawm ib zaug -suction twj, ua kom nws khiav zoo dua. Ntxiv mus, qhov khiav ceev ntawm qhov nruab nrab yog qis dua, thiab lub impeller tsis tshua muaj kev cuam tshuam cavitation.
4. Txawv daim ntawv thov scenarios
(1) Lub twj tso kua mis kawg yog hom twj tso kua dej siv dav hauv kev ua liaj ua teb. Lub twj tso kua mis ob npaug feem ntau yog siv rau kev siv dej thiab tso dej hauv mines, nroog, chaw nres tsheb fais fab, thiab ntau yam kev txuag dej.
(2) Qhov kawg nqus twj tso kua mis feem ntau muaj qhov ntws me me. Nws qhov zoo dua yog nyob rau hauv qhov sib npaug ntawm tus nqi ntws, qhov ntim ntawm qhov kawg nqus twj tso kua mis me dua, tab sis lub zog axial ntau dua thiab cov kabmob hnyav dua. Piv nrog rau ob chav nqus twj tso kua mis, nws muaj ntau yam kev txwv. Nyob rau hauv cov nqe lus ntawm kev siv, qhov zoo ntawm ob chav nqus dej twj tso kua mis yog pom tseeb dua.

V. Kev ceev faj rau cov twj centrifugal
Qhov saum npoo ntawm lub hauv paus nruab yuav tsum tiaj tus, huv si thiab muaj peev xwm tiv taus qhov sib txuam.
2. Nyob rau hauv qhov chaw ruaj khov, yuav tsum siv cov bolts.
3. Rau cov twj tso kua mis vertically, lub thauj tog rau nkoj bolts yuav tsum muaj lub zog txaus.
4. Yog tias ntsia vertically, lub cev muaj zog yuav tsum muab tso rau saum lub twj tso kua dej.
5. Thaum kho rau ntawm phab ntsa, xyuas kom meej thiab nruab nrab kom zoo.
