Abstract

Raws li cov khoom siv thauj khoom muaj txiaj ntsig zoo tau siv dav hauv cov dej txuag dej, kev lag luam petrochemical, thiab cov kav dej hauv nroog, ntau theem ntsug turbine twj tso nyiaj rau 30% -50% ntawm tag nrho cov kev siv hluav taws xob. Cov txheej txheem tswj kev ceev ceev tsis tu ncua raug kev txom nyem los ntawm lub zog pov tseg vim lawv tsis muaj peev xwm ua kom muaj zog txaus nyiam cov kev xav tau. Nrog kev loj hlob ntawm kev hloov pauv ceev ceev tswj (VFS) thev naus laus zis, nws daim ntawv thov hauv kev txuag hluav taws xob raumultistage ntsug turbine twj tso kua mistau dhau los ua qhov tseem ceeb hauv kev lag luam. Daim ntawv no tshawb txog cov txiaj ntsig tseem ceeb ntawm VFS cov txheej txheem los ntawm cov txheej txheem thev naus laus zis, cov txiaj ntsig siv hluav taws xob txuag hluav taws xob, thiab kev xav txog nyiaj txiag.

I. Cov Ntsiab Cai thiab Kev Txhim Kho ntawm Kev Sib Txuas Lus Ceev Tswj Systems rau Multistage Vertical Turbine Pumps

1.1 Cov Ntsiab Cai Tseem Ceeb ntawm Kev Tswj Xyuas Kev Ntsuas Ceev

VFS systems kho lub cev muaj zog fais fab zaus (0.5-400 Hz) los tswj lub twj tso kua mis ceev (N∝f), yog li tswj tus nqi ntws (Q∝N³) thiab lub taub hau (H∝N²). Core controllers (piv txwv li, VFDs) siv PID algorithms rau kev tswj kev ntws-siab los ntawm kev hloov pauv zaus.

1.2 Cov yam ntxwv ua haujlwm ntawm Multistage Vertical Turbine Pumps thiab Lawv Adaptability rau VFS

Ntsiab ntaiNtxiv:
• Nqaim ntau qhov ua tau zoo: Kev ua haujlwm poob qis thaum ua haujlwm deb ntawm cov ntsiab lus tsim
• Kev hloov pauv loj loj: Yuav tsum tau hloov kho sai sai lossis pib-nres ua haujlwm vim system kev hloov pauv siab
• Cov kev txwv ntev ntawm cov qauv: Cov tsoos valve throttling ua rau lub zog poob thiab kev co teeb meem

VFS ncaj qha kho qhov nrawm kom ua tau raws li qhov yuav tsum tau ua, tsis txhob muaj qhov ua haujlwm qis thiab txhim kho kev ua haujlwm zoo.

II. Energy-Saving Effectiveness Analysis of Variable Frequency Speed ​​Control Systems

2.1 Cov Txheej Txheem Tseem Ceeb rau Kev Txhim Kho Kev Siv Hluav Taws Xob

(Qhov twg ΔPvalve sawv cev valve throttling siab poob)

2.2 Cov ntaub ntawv thov siv tau

• **Dej Supply Plant Retrofit Project:**

· Khoom siv: 3 XBC300-450 multistage ntsug twj tso kua mis (155 kW txhua)

· Ua ntej Retrofit: Kev siv hluav taws xob txhua hnub ≈ 4,200 kWh, tus nqi txhua xyoo ≈$39,800

· Tom qab Retrofit: Kev noj txhua hnub txo mus rau 2,800 kWh, kev txuag nyiaj txhua xyoo ≈$24,163, lub sijhawm them rov qab <2 xyoos

III. Kev ntsuam xyuas nyiaj txiag thiab kev nqis peev rov qab tsom xam

3.1 Tus nqi sib piv ntawm cov txheej txheem tswj

3.2 Kev nqis peev them rov qab rau lub sijhawm suav

Piv txwv li: Cov khoom siv nqi nce$27,458, nyiaj txiag txhua xyoo$24,163 → ROI ≈ 1.14 xyoo

3.3 Hidden Economic Benefits

• Cov khoom siv txuas ntxiv lub neej: 30% -50% lub sijhawm ua haujlwm ntev dua vim tias txo cov kabmob hnav
• Cov pa roj carbon emission txo: Ib lub twj tso kua mis txhua xyoo CO₂ emissions txo los ntawm ~ 45 tons ib 50,000 kWh txuag
• Txoj cai txhawb nqa: Ua raws li Tuam Tshoj tus Industrial Energy Conservation Diagnosis Guidelines, tsim nyog rau kev pab nyiaj ntsuab tech

 IV. Case Study: Petrochemical Enterprise Multistage Pump Group Retrofit

4.1 Project Background

• Teeb meem: nquag pib-nres ntawm cov roj av hloov twj tso kua mis ua rau cov nqi tu txhua xyoo >$109,832 vim system kev hloov pauv siab
• Kev daws: Kev teeb tsa ntawm 3 × 315 kW VFDs nrog lub siab sensors thiab huab xyuas platform

4.2 Cov txiaj ntsig ntawm kev siv

• Kev ntsuas hluav taws xob: Ib lub twj siv hluav taws xob txo qis ntawm 210 kW mus rau 145 kW, kev ua haujlwm tau zoo tuaj ntawm 32%
• Cov nqi khiav lag luam: Kev poob qis poob qis los ntawm 75%, cov nqi tu txhua xyoo txo ​​rau$27,458.
• Cov txiaj ntsig nyiaj txiag: Tag nrho cov nqi rov qab tau rov qab los hauv 2 xyoos, cov nyiaj tau los sib npaug >$164,749

V. Yav Tom Ntej Trends and Recommendations

1. Kev txawj ntse txawj ntse: Kev koom ua ke ntawm IoT thiab AI algorithms rau kev tswj xyuas lub zog

2. High-Pressure Applications: Kev loj hlob ntawm VFDs haum rau 10 kV + multistage twj

3. Kev tswj hwm lub neej: Tsim kom muaj cov qauv ntxaib digital rau kev siv hluav taws xob zoo rau lub neej zoo

xaus
Kev hloov pauv ceev ceev tswj cov tshuab ua tiav kev txhim kho kev siv hluav taws xob tseem ceeb thiab kev ua haujlwm txo nqi hauv ntau theem ntsug turbine twj los ntawm kev sib piv cov kev xav tau ntawm lub taub hau. Cov ntaub ntawv tshawb fawb pom tau tias cov nyiaj them rov qab ntawm 1-3 xyoo nrog cov txiaj ntsig zoo ntawm kev lag luam thiab ib puag ncig. Nrog rau kev nce qib kev lag luam digitization, VFS thev naus laus zis yuav nyob twj ywm hauv kev daws teeb meem rau lub zog ua kom zoo dua.
