Hauv kev lag luam, hauv nroog thiab kev ua liaj ua teb, kev xaiv cov siab - cov twj tso kua mis ncaj qha cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm ruaj khov ntawm cov haujlwm. Kab lus no piav qhia koj yuav ua li cas rau kev tshawb fawb xaiv siab - taub hau thiab siab - ntws twj tso kua mis los ntawm peb qhov ntev: xaiv lub hauv paus, twj tso kua mis thiab cov xwm txheej siv tau.
1. Tsib yam tseem ceeb rau kev xaiv cov twj tso kua dej
Tsheb thauj mus los: Raws li qhov siab tshaj plaws tsheb thauj mus los, cov kev xaiv ib txwm siv 1.1 npaug ntawm cov tsheb khiav ib txwm muaj.
Lub taub hau yuav tsum tau: Lub taub hau tiag tiag yuav tsum tau nce 5% mus rau 10% raws li kev nyab xeeb.
Cov yam ntxwv ntawm cov khoom: Kub, viscosity, corrosiveness, thiab tshem tawm cov ntsiab lus cuam tshuam ncaj qha rau kev xaiv cov khoom.
Pipeline system: Qhov ntev, kev taw qhia thiab cov khoom siv ntawm cov kav dej txiav txim siab qhov poob thiab qhov cavitation npoo.
Kev ua haujlwm ib puag ncig: Qhov siab, qhov kub thiab txias, thiab hom kev ua haujlwm (nruam / ncua) cuam tshuam rau lub zog ntawm cov khoom siv.
II. Kev sib piv ntawm Mainstream High -Flow Pump Types
Pump Hom Hom Qauv Flow Range (m³/h) Lub Taub Hau Ntau (m) Nruab Nrab Kub (℃) Core Application Kab rov tav Multi-stage Pump
D Hom 6.3 - 600 50 - 1300 Tsawg dua los yog sib npaug li 80 Mine ntws, dej hauv nroog, fais fab nroj tsuag circulating dej, boiler feed twj DG hom 10 - 200 50 - 1200 - 20 ~ 150 Muaj boiler system, siab -kub nruab nrab tsheb thauj mus los Kab rov tav Split Pump CPS hom 72 - 1080 012 - 125 Tsawg tshaj los yog sib npaug rau 80 Agricultural kav dej siab, irrigation network Multi-stage Pump GDL Hom
2 - 40024 - 240 Tsawg dua los yog sib npaug rau 120 Rau siab - cov tsev nce siab, cov dej thiab hluav taws xob tiv thaiv yuav tsum muaj kev txhawb zog.
III. Xaiv tsob ntoo txiav txim
Kauj Ruam 1: Kev txiav txim siab nruab nrab
Cov dej huv nruab nrab: nyiam S hom / SH hom
High-temperature medium (>80 degree): Xaiv hom DG
Corrosive nruab nrab: Siv GDL hom stainless hlau version (304/316L)
Kauj Ruam 2: Qhov chaw txwv
Qhov chaw yog nqaim: Vertical GDL hom (txo hauv pem teb los ntawm 40%)
Standard chaw: Kab rov tav D-type/DG- hom
Kauj Ruam 3: Kev Siv Hluav Taws Xob Hluav Taws Xob
Kev siv hluav taws xob siab yuav tsum tau ua: S / SH hom cais twj tso kua mis (ua tau zoo txog 92%)
Qhov yuav tsum tau muaj: D-hom multi- theem twj tso kua mis (efficiency 85% - 90%)
Kauj Ruam 4: Cov nqi kho mob
Kev tu ncua sij hawm: Xaiv S/SH hom (nruab nrab- qhib qauv rau kev saib xyuas yooj yim)
Ntev -kev tu lub sij hawm- qhov yuav tsum tau pub dawb: GDL hom (hard alloy mechanical seal muaj lub neej ua haujlwm tshaj 20,000 teev)
IV. Cov phiaj xwm teb rau cov xwm txheej tshwj xeeb
Particulate-muaj nruab nrab: Nws raug nquahu kom nruab ib lub tshuab pom ua ntej D- hom twj tso kua mis (particle loj Tsawg dua lossis sib npaug li 0.5mm)
Kev tsis zoo siab: Hom DG tau tso cai kom muaj qhov nkag siab ntawm 0.6 MPa, thiab lub tshuab nqus tsev tuaj yeem tsim kho.
Kev hloov pauv zaus: GDL hom yog sib xws nrog zaus hloov pauv tswj qhov system, uas tuaj yeem txhim kho lub zog -txuag nyhuv los ntawm 25% - 40%
Tsawg- qhov kub thiab txias: DG hom kev them nyiaj yug - ua haujlwm ntawm -20℃qhov kub thiab txias, yuav tsum tau ua kom muaj kev sib khi ruaj khov.
V. Cov lus pom zoo rau kev thov kev lag luam
Municipal Engineering: S / SH hom tandem twj tso kua mis (tus nqi zoo tshaj -kev ua tau zoo piv thaum tus nqi ntws yog> 500 m³ / h)
Petrochemical kev lag luam: DG hom + 316L stainless hlau (tiv taus kub thiab corrosion)
Agricultural irrigation: S/SH hom ob -suction twj (nrog tus nqi ntws loj thiab cov yam ntxwv ntawm lub taub hau qis, haum rau cov dej ntws)
High-cov tsev nce siab: LC ntsug ntev twj tso kua mis (kev ua haujlwm ntsiag to, nrog rau qhov siab txog li 240 meters)
Kev txhim kho kev lag luam: Cov khoom lag luam tseem ceeb tam sim no tau txais kev tsim qauv, xws li CPS hom twj tso kua mis ntev los ntawm Kellyte Pump Kev Lag Luam.
Cov qauv impeller detachable tau txais yuav, tso cai rau hloov ceev ntawm cov khoom ntws ntawm -site. Nws raug nquahu kom xaiv lub twj tso kua mis uas tau dhau API610 daim ntawv pov thawj kom ntseeg tau tias muaj kev ntseeg siab nyob rau hauv huab cua.
Los ntawm kev txheeb xyuas kev xaiv, kev siv hluav taws xob ua haujlwm tuaj yeem txo qis dua 30%, thiab kev pabcuam lub neej ntawm cov cuab yeej tuaj yeem txuas ntxiv los ntawm 50%. Nws raug nquahu kom ua CFD flow field simulation pov thawj ua ntej txiav txim siab zaum kawg. Tshwj xeeb tshaj yog rau super- tej yaam num loj nrog tus nqi ntws ntawm > 1000 m³ / h, nws yog ib qho tsim nyog los muab cov NPSHr tus nqi rau kev txheeb xyuas los tiv thaiv cavitation.
