Peb lub tuam txhab nyuam qhuav xa ib pawg ntawm cov twj tso kua tshuaj ZA series zoo rau ib qhov project petrochemical loj raws sijhawm, txhawb nqa PLAN53 mechanical seal scheme, uas qhia tag nrho peb lub zog kev tshaj lij hauv kev muab khoom siv hauv qab cov xwm txheej ua haujlwm hnyav. Cov twj tso kua mis no tau tsim thiab tsim tawm raws li API 610 "Centrifugal Pumps for Petroleum, Heavy Chemical and Natural Gas Industries" tsab 10, thiab lawv cov kev ua tau zoo heev thiab qhov zoo txhim khu kev qha muab kev lees paub zoo rau kev ua haujlwm zoo ntawm qhov project.
Cov ntsiab lus tseem ceeb ntawm kev siv tshuab thiab kev tsim qauv tshiab
Lub twj tso kua mis ZA series siv cov qauv cantilever ib theem ib zaug kom ua tiav cov kua dej zoo ntawm kev nqus kab rov tav thiab tso tawm ntsug, thiab koom tes nrog kev tsim qauv txhawb nqa ko taw kom ntseeg tau tias cov khoom siv ua haujlwm ruaj khov. Nws cov kev ua haujlwm hydraulic yog raws li tus qauv hydraulic thoob ntiaj teb, thiab tau ua kom zoo dua los ntawm PUMPCAD pab tsim qauv thiab CFD peb-seem kua simulation thev naus laus zis kom ua tiav qib kev siv hluav taws xob zoo tshaj plaws hauv kev lag luam.
Kev ua haujlwm siab thiab kev siv tsawg:Tus qauv tsim impeller tshiab thiab cov qauv ob chav volute (DN80 lossis siab dua hom twj tso kua mis) ua kom sib npaug lub zog radial, txo kev co thiab suab nrov, ua kom lub neej ntawm cov kabmob ntev dua, thiab txhim kho kev ua haujlwm zoo dua.
Kev tswj cavitation:Los ntawm qhov ua haujlwm sib koom ua ke ntawm cov nplhaib hnav thiab qhov sib npaug ua ntej thiab tom qab lub impeller, tus nqi NPSHr tau raug kho kom zoo dua kom tau raws li qhov xav tau ntawm cov xwm txheej ua haujlwm siab NPSH.
Txhim khu kev qha thiab ruaj khov:Tus qauv tsim uas suav nrog txhua yam tsis muaj kev sib cuag nrog cov khoom nruab nrab, ua ke nrog lub impeller kaw, uas ua rau cov khoom siv tiv taus corrosion thiab lub neej ua haujlwm zoo dua. Lub kaw lus foob pob hluav taws xob ua raws li tus qauv API 682 tshiab kawg kom ntseeg tau tias kev ua haujlwm ruaj khov mus sij hawm ntev.
Muaj zog hloov kho tau:ua tau raws li qhov ua tau zoo ntawm cov kev ua haujlwm hauv qab no, thiab hloov kho tag nrho rau cov xwm txheej ua haujlwm hnyav.
| Txoj kab uas hla | 25 ~ 400 hli | ntws | Txog li 2600m3 / teev |
| Lub taub hau | Mus txog 300m | Kub | -80~450℃ |
| Siab | Txog li 5MPa | qhov ceev | 1480 ~ 3560r / feeb |
Cov kev daws teeb meem khoom siv
Cov khoom siv ntawm cov khoom siv ua raws li API 610 cov lus qhia, thiab muaj kev pabcuam sib phim raws li qhov xav tau. Cov khoom siv ntawm lub cev twj tso kua mis tau sib phim raws li qib siab, cov khoom tseem ceeb yog ua los ntawm cov hlau sib xyaw tshwj xeeb thiab cov khoom siv tiv taus corrosion, thiab lub kaw lus sib khi pabcuam xa mus rau cov qauv cai xws li "Industrial Pump Design Manual" kom ntseeg tau tias txhua yam kev ua haujlwm tau hloov kho.
Kev Cog Lus Pabcuam
Peb lub tuam txhab muaj ib pab neeg kws ua haujlwm tshaj lij los muab kev txhawb nqa kev siv tshuab thiab kev daws teeb meem raws li koj xav tau. Txij li kev xaiv thiab kev tsim qauv, kev siv cov khoom siv kom zoo mus txog kev teeb tsa hauv tsev, peb tuaj yeem ua kom lub neej ntawm cov khoom siv siv tau ntev tshaj plaws, thiab pab cov neeg siv khoom ua tiav cov hom phiaj tsim khoom kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Nrog rau kev ua tau zoo heev thiab qhov zoo ntawm lub twj tso kua mis ZA uas tau xa tuaj rau lub sijhawm no, peb yuav txuas ntxiv tsim kho tshiab yav tom ntej los muab cov kev daws teeb meem hloov pauv kua dej kom zoo dua thiab txuag hluav taws xob rau kev lag luam petrochemical.
