abstract

Njengemishini yokuthutha uketshezi esebenza kahle kakhulu esetshenziswa kabanzi kumaphrojekthi okonga amanzi, imboni ye-petrochemical, kanye nezinhlelo zokuphakelwa kwamanzi emadolobheni, amaphampu e-multistage turbine turbine amaphampu angu-30% -50% wengqikithi yokusetshenziswa kwamandla esistimu. Izindlela ezivamile zokulawula isivinini esingaguquki zihlushwa ukumosheka kwamandla ngenxa yokungakwazi kwazo ukuhambisana nezidingo zokugeleza. Ngokuvuthwa kobuchwepheshe be-variable frequency control (VFS), ukusetshenziswa kwayo ekongeni amandlaamaphampu e-multistage mpoisibe yisizinda esikhulu embonini. Leli phepha lihlola ukubaluleka kwezinhlelo ze-VFS kusukela kuzimiso zobuchwepheshe, imiphumela esebenzayo yokonga amandla, kanye nemibono yezomnotho.

I. Izimiso Zobuchwepheshe kanye Nokuguquguquka Kwezisistimu Zokulawula Isivinini Esishintshashintshayo Kumaphampu e-Multistage Vertical Turbine

1.1 Izimiso Eziyisisekelo Zokulawula Isivinini Esishintshashintshayo

Amasistimu e-VFS alungisa imvamisa yokunikezwa kwamandla emoto (0.5–400 Hz) ukuze alawule isivinini sepompo (N∝f), ngaleyo ndlela alawule izinga lokugeleza (Q∝N³) nekhanda (H∝N²). Izilawuli eziyinhloko (isb., ama-VFD) zisebenzisa ama-algorithms e-PID ukulawula ukugeleza kwengcindezi ngokulungiswa okuguquguqukayo.

1.2 Izici Zokusebenza Zamaphampu e-Multistage Vertical Turbine kanye Nokujwayela kwawo ku-VFS

Izimpawu ezisemqokaihlanganisa:
• Ububanzi obusebenza kahle kakhulu obuncane: Ithambekele ekwehleni ngokusebenza kahle lapho isebenza kude nezindawo zokuklama
• Ukushintshashintsha kokugeleza okukhulu: Kudinga ukulungiswa njalo kwesivinini noma imisebenzi yokumisa ngenxa uhlelo ukuhluka kwengcindezi
• Imikhawulo emide yesakhiwo se-shaft: Ukunyakaziswa kwama-valve okuvamile kubangela ukulahlekelwa amandla kanye nezinkinga zokudlidliza

I-VFS ilungisa ngokuqondile isivinini ukuze ihlangabezane nezidingo zokugeleza, igwema izindawo ezingasebenzi kahle futhi ithuthukise kakhulu ukusebenza kahle kwesistimu.

II. Ukuhlaziywa Kokusebenza Kokonga Amandla Kwezinhlelo Zokulawula Isivinini Esishintshashintshayo

2.1 Izindlela Ezibalulekile Zokuthuthukisa UkuSebenzisa Kahle Emandla

(Kuphi ΔPI-valve imele i-valve throttling pressure loss)

2.2 Idatha Yendaba Yesicelo Esisebenzayo

• **Iphrojekthi Yokubuyisela Isitsha Sokuhlinzeka Ngamanzi:**

· Izisetshenziswa: 3 XBC300-450 amaphampu aqondile esiteji amaningi (155 kW lilinye)

· Ngaphambi Kokubuyisela: Ukusetshenziswa kukagesi nsuku zonke ≈ 4,200 kWh, izindleko zonyaka ≈$39,800

· Ngemuva kokubuyiselwa imali: Ukusetshenziswa kwansuku zonke kwehlisiwe kwaba ngu-2,800 kWh, ukonga ngonyaka ≈$24,163, isikhathi sokukhokha < 2 iminyaka

III. Ukuhlolwa Komnotho kanye Nokuhlaziywa Kwembuyiselo Yokutshalwa Kwezimali

3.1 Ukuqhathaniswa Kwezindleko Phakathi Kwezindlela Zokulawula

3.2 Ukubalwa Kwenkathi Yenkokhelo Yokutshalwa Kwezimali

Isibonelo: Ukukhuphuka kwezindleko zezisetshenziswa$27,458, ukonga konyaka$24,163 → I-ROI ≈ iminyaka engu-1.14

3.3 Izinzuzo Zezomnotho Ezifihliwe

• Ukuphila kwemishini enwetshiwe: 30% -50% umjikelezo wokunakekela omude ngenxa yokuncipha kokuguga
• Ukunciphisa ukukhishwa kwekhabhoni: Iphampu elilodwa lokukhishwa kwe-CO₂ minyaka yonke lehliswe ngamathani angu-~45 ngo-50,000 kWh ngayinye elondoloziwe
• Izinzuzo zenqubomgomo: Ihambisana ne-China Izinkombandlela Zokuxilongwa Kokongiwa Kwezimboni, kufanelekile ukuthola uxhaso lwezobuchwepheshe obuluhlaza

 IV. Indaba eyisibonelo: I-Petrochemical Enterprise Multistage Pump Group Retrofit

Isendlalelo Sephrojekthi

• Inkinga: Ukumiswa njalo kwamaphampu okudlulisa uwoyela ongahluziwe kubangele izindleko zonyaka zokulungisa >$109,832 ngenxa ye uhlelo ukushintshashintsha kwengcindezi
• Isixazululo: Ukufakwa kwama-VFD angu-3×315 kW anezinzwa zokucindezela kanye nenkundla yokuqapha ifu

4.2 Imiphumela Yokuqalisa

• Amamethrikhi wamandla: Ukusetshenziswa kwamandla kwephampu ngayinye kwehlisiwe ukusuka ku-210 kW kuya ku-145 kW, ukusebenza kahle kwesistimu kube ngcono ngo-32%.
• Izindleko zokusebenza: Isikhathi sokungasebenzi sehle ngo-75%, izindleko zonyaka zokulondoloza zehliswa zaba$27,458.
• Izinzuzo zomnotho: Izindleko eziphelele zokubuyisela zibuyiselwe phakathi neminyaka emi-2, inzuzo enqwabelanayo >$164,749

V. Amathrendi Akusasa Nezincomo

1. Ukuthuthukiswa Okukhaliphile: Ukuhlanganiswa kwe-IoT ne-AI ama-algorithms wokulawula amandla okubikezela

2. Izicelo Zokucindezela Okuphezulu: Ukuthuthukiswa kwama-VFD afanele amaphampu angu-10 kV+ esiteji esiningi

3. Ukuphathwa kwe-Lifecycle: Ukusungulwa kwamamodeli angamawele edijithali okuthuthukisa umjikelezo wempilo ukonga amandla

Isiphetho
Amasistimu okulawula isivinini esishintshashintshayo azuza ukuthuthukiswa kokusebenza kahle kwamandla kanye nokwehliswa kwezindleko zokusebenza kumaphampu e-turbine amile ezigaba eziningi ngokufanisa ngokunembile izidingo zekhanda lokugeleza. Ucwaningo lwezehlakalo lubonisa izikhathi zokukhokha ezijwayelekile zeminyaka engu-1–3 ngezinzuzo ezinkulu zezomnotho nezemvelo. Ngokuthuthuka kokufakwa kwedijithali kwezimboni, ubuchwepheshe be-VFS buyohlala buyisixazululo esijwayelekile sokwenziwa ngcono kwamandla ephampu.
