Kab rov tav Multistage Centrifugal Pump
Kab rov tav Multistage Centrifugal Pump|Technical Specification & Engineering Guide
Product Overview & Engineering Architecture
Kab rov tav Multistage Centrifugal Pump siv ntau lub impellers mounted rau ntawm ib tug nruj kab rov tav ncej nyob rau hauv ib tug segmented los yog sectional casing. Txhua theem ntxiv qhov siab ntxiv rau cov kua dej ua haujlwm. Qhov kev teeb tsa no muab lub taub hau tawm zoo li qub thaum tuav cov hneev taw me me piv rau ib qho - theem sib npaug ua haujlwm ntawm qhov nrawm heev.

Kev Qhia Txog Kev Xaiv (Yuav ua li cas kom loj lub twj tso kua mis no)
Xaiv lub twj tso kua mis ntau-theem theem yuav tsum tau ua raws li cov kev ntsuas hydraulic kom tsis txhob muaj cavitation, hydraulic overload, lossis kev qaug zog. Siv cov txheej txheem hauv qab no los txiav txim siab koj qhov tshwj xeeb:
Txiav txim siab lub luag haujlwm Point:Txheeb xyuas qhov xav tau Flow Rate (Q) thiab Total Dynamic Head (H). Xaiv lub twj tso kua mis qhov twg Qhov Qhov Ua Tau Zoo Tshaj Plaws (BEP) ua haujlwm li ntawm 75% txog 115% ntawm koj lub hom phiaj taw tes.
Calculate NPSH Margin:Txheeb xyuas qhov system muaj NPSHa. Xyuas kom meej tias NPSHA > NPSHr + 0.5 meters los tiv thaiv kev puas tsuaj npuas ntawm impeller vanes.
Ntsuas Cov Khoom Siv Dej:Tshawb xyuas lub ntiajteb txawj nqus, viscosity, thiab tshuaj lom neeg concentration. Kho lub cev muaj zog horsepower yog tias lub ntiajteb txawj nqus tshaj dej (SG> 1.0).
Xaiv Sealing Arrangement:Xaiv ib qho khoom siv tsis sib xws rau cov dej huv; qhia meej tungsten carbide vs. silicon carbide ntsej muag los yog flushed dual pressurized seals rau abrasive los yog siab -kub kua.
Cov ntaub ntawv ntawm Kev Tsim Kho & Kev Tsim Khoom Metallurgy
Durability nyob rau hauv sustained siab siab nyob ntawm cov khoom xaiv thiab casting kev ncaj ncees. Peb tuav tag nrho cov ntaub ntawv traceability rau tag nrho cov wetted Cheebtsam.

Daim Ntawv Thov Matrix & Kev Lag Luam Compatibility
Peb cov twj tso kua mis kab rov tav multistage yog tsim los rau cov tshuab ua kua dej uas xav tau kev xa khoom zoo sib xws:
Rov qab Osmosis (RO) & Desalination:Siab -siab pub khoom xa tuaj rau cov dej hiav txwv thiab cov dej lim dej lim dej.
Boiler Feed Systems:Cov dej pleev tsis tu ncua rau qhov nruab nrab - lub zog ntawm cov boilers ua haujlwm txog li 150℃.
Industrial Pressure Boosting:Kev txhawb nqa dej hauv nroog hauv nroog, ntau- zaj dab neeg hauv tsev siv dej, thiab siab - lub zog ntxhua khaub ncaws.
Txheej Txheem Txias & HVAC:Kaw -loop chilled dej ncig nyob rau hauv loj - teev cov ntaub ntawv chaw thiab chaw tsim khoom.
Manufacturing, Quality Control & Factory Testing
Txhua lub twj tso kua mis dhau qhov kev nruj nruj thiab kev siv hydraulic ua ntej xa tawm los ntawm peb qhov chaw tsim khoom ISO 9001-certified.
Machining:CNC kab rov tav tho txawv thiab milling chaw xyuas kom nruj coaxiality kam rau ua (<= 0.03 mm) across multi-stage casing segments, eliminating vibration caused by shaft runout.
Dynamic Balancing:Tag nrho cov impellers thiab rotor sib dhos yog dynamically sib npaug rau ISO 1940 Qib G2.5 cov qauv kom txuas cov tshuab foob thiab cov kabmob lifespan.
Kev Ntsuas Hydrostatic:Pump casings yog pressurized mus rau 1.5 lub sij hawm siab tshaj plaws tso cai ua hauj lwm siab (MAWP) rau 30 feeb los xyuas cov casting porosity los yog weld defects.
Kev Ntsuas Kev Ua Haujlwm: Kev ntsuas qhov ntsuas qhov ntsuas qhov ntsuas ntws, lub taub hau, lub zog, thiab kev ua haujlwm zoo raws li ISO 9906 Qib 2B (lossis Qib 1B raws li kev thov) cov qauv. Certified test curves yog muab nrog txhua yam khoom xa tuaj.
Cov lus nug nquag
Q: Koj ua li cas tiv thaiv axial thrust unbalance nyob rau hauv multi-theem twj?
A: Raws li cov kua txav mus los ntawm ntau theem, kev sib txuas siab ua rau lub zog axial tseem ceeb thawb mus rau qhov kawg nqus. Peb neutralize qhov no los ntawm hydraulic ntsuas nruas, ntsuas discs, los yog rov qab - mus rau - rov qab impeller configurations ua ke nrog hnyav - lub luag hauj lwm angular contact thrust bearings kom nqus cov seem seem.
Q: Dab tsi yog qhov txheej txheem kev teeb tsa lub tshuab foob, thiab nws puas tuaj yeem tuav cov kua abrasive?
A: Cov txheej txheem siv cov pa roj carbon / silicon-carbide mechanical seals nrog Viton elastomers haum rau cov dej huv txog li 120 degree. Rau cov kua uas muaj cov khib nyiab tshem tawm lossis cov abrasives (TSS> 50 ppm), peb pom zoo kom hloov kho kom tawv nqaij - ntsib cov tungsten carbide seals nrog rau kev npaj sab nraud (API Plan 11 lossis 32).
Q: Cov twj no puas tuaj yeem khiav tawm ntawm lub valve kaw?
A: Kev ua haujlwm ib ntus tiv thaiv lub qhov tso tawm kaw tau tso cai rau lub sijhawm luv luv (hauv qab 1 feeb) thaum pib lossis thawj zaug. Kev kaw txuas ntxiv- lub valve ua haujlwm ua rau cov cua kub ceev thiab vapor kaw, ua rau lub impeller puas tsuaj loj. Qhov tsawg kawg nkaus bypass kab los yog thermal nyem valve yog pom zoo rau cov tshuab automated.
Q: Koj lub sij hawm xa tuaj raws sij hawm yog dab tsi rau cov khoom tsis yog - qauv teeb tsa?
A: Cov qauv kev teeb tsa uas siv cov hlau cam khwb cia thiab SS304 feem ntau yog khaws cia rau kev sib dhos hauv 2 mus rau 3 lub lis piam. Kev cai configurations yuav tsum tau tshwj xeeb metallurgy (xws li Duplex SS2205 los yog titanium wetted qhov chaw) feem ntau yuav tsum tau 6 mus rau 8 lub lis piam, nyob ntawm seb cov khoom siv raw casting muaj.
Q: Yuav ua li cas cov ntaub ntawv yuav tsum tau ua kom muaj tseeb twj tso kua mis sizing hais?
A: Txhawm rau ua tiav kev xaiv hydraulic, thov muab:
Target Flow Rate (Q) thiab Lub Taub Hau (H)
Lub ntiajteb txawj nqus, viscosity, thiab tshuaj muaj pes tsawg leeg ntawm cov kua
Pumping kub thiab muaj NPSHa
Fais fab mov specifications (Voltage / Frequency / Phase)
Yuav tsum muaj kev ntsuas lub cev muaj zog (piv txwv li, TEFC, Kev tawg- pov thawj Ex-d IIBT4)
Q: Cov ntawv pov thawj thiab cov ntaub ntawv pov thawj dab tsi yog muab nrog kev xa khoom?
A: Txhua qhov khoom xa tuaj suav nrog Kev Ua Haujlwm & Kev Saib Xyuas (O&M) Phau Ntawv Qhia, Cov Ntawv Qhia Txog Cov Khoom Siv (MTRs) rau cov khoom ntub dej ntawm EN 10204 3.1, daim ntawv qhia txog kev ntsuas lub Hoobkas, thiab ib tus neeg ISO 9906 daim ntawv pov thawj kev ua haujlwm hydraulic. Thib peb-kev soj ntsuam tog los ntawm SGS, BV, lossis TÜV tuaj yeem npaj ua ntej xa.
