Kudalirika

Monga zida zoyendetsera bwino kwambiri zamadzimadzi zomwe zimagwiritsidwa ntchito kwambiri pama projekiti osungira madzi, mafakitale a petrochemical, ndi makina operekera madzi akutawuni, mapampu amagetsi ophatikizika ambiri amakhala ndi 30% -50% yakugwiritsa ntchito mphamvu zonse. Njira zachikale zowongolera kuthamanga kosalekeza zimavutitsidwa ndi kuwononga mphamvu chifukwa cholephera kugwirizana ndi zomwe zimafunikira kuyenda. Ndi kukula kwa ukadaulo wa variable frequency control control (VFS), kugwiritsa ntchito kwake pakupulumutsa mphamvumapampu a turbine multistage of vertical turbineyakhala malo ofunika kwambiri pamakampani. Pepalali likuwunikira phindu lalikulu la machitidwe a VFS kuchokera ku mfundo zaumisiri, zopindulitsa zopulumutsa mphamvu, komanso momwe chuma chikuyendera.

I. Mfundo Zaumisiri ndi Kusintha kwa Makina Osinthira Kuthamanga Kwachangu kupita ku Multistage Vertical Turbine Pump

1.1 Mfundo Zazikulu Zakusinthasintha Kwachangu Kuthamanga

Makina a VFS amasintha ma frequency amagetsi amagetsi (0.5–400 Hz) kuti azitha kuyendetsa liwiro la mpope (N∝f), potero amawongolera kuthamanga (Q∝N³) ndi mutu (H∝N²). Olamulira apakati (mwachitsanzo, ma VFD) amagwiritsa ntchito ma algorithms a PID kuti azitha kuyendetsa bwino kuthamanga kwamphamvu kudzera pakusintha pafupipafupi.

1.2 Makhalidwe Ogwirira Ntchito a Multistage Vertical Turbine Pump ndi Kusintha Kwawo ku VFS

zinthu zikuluzikuluizopanda nzeru:
• Kuchepa kwa magwiridwe antchito apamwamba: Kutha kutsika bwino mukamagwira ntchito kutali ndi malo opangira
• Kusinthasintha kwakukulu koyenda: Kumafuna kusintha pafupipafupi kapena kuyimitsa ntchito chifukwa cha dongosolo kusiyanasiyana kwamphamvu
• Kulephera kwa ma shaft aatali: Kugwedezeka kwa ma valve kwachizoloŵezi kumayambitsa kutaya mphamvu ndi kugwedezeka

VFS imasintha mwachindunji liwiro kuti ikwaniritse zofunikira zoyenda, kupewa madera osagwira ntchito bwino ndikuwongolera kwambiri magwiridwe antchito.

II. Kugwiritsa Ntchito Mphamvu Zopulumutsa Mphamvu Kusanthula kwa Variable Frequency Speed ​​Control Systems

2.1 Njira Zazikulu Zothandizira Kuwongola Mphamvu Zamagetsi

(Kuti ΔPvavu imayimira kutsika kwamphamvu kwa valve)

2.2 Zambiri Zogwiritsa Ntchito

• **Pulojekiti Yobwezeretsanso Malo Opangira Madzi:**

· Zida: 3 XBC300-450 mapampu ofukula angapo (155 kW iliyonse)

· Pamaso pa Retrofit: Kugwiritsa ntchito magetsi tsiku lililonse ≈ 4,200 kWh, mtengo wapachaka ≈$39,800

· Pambuyo pa Retrofit: Kugwiritsa ntchito tsiku ndi tsiku kumachepetsedwa mpaka 2,800 kWh, kupulumutsa pachaka ≈$24,163, nthawi yobweza <2 years

III. Kuwunika kwa Economic and Investment Return Analysis

3.1 Kuyerekeza Mtengo Pakati pa Njira Zowongolera

3.2 Kuwerengera Nthawi Yobwezera Malipiro

Chitsanzo: Kukwera mtengo kwa zipangizo$27,458, ndalama zosungira pachaka$24,163 → ROI ≈ zaka 1.14

3.3 Ubwino Wobisika Pazachuma

• Kutalika kwa moyo wa zipangizo: 30% -50% nthawi yayitali yokonza chifukwa cha kuchepa kwa mavalidwe
• Kuchepetsa mpweya wa carbon: Pampu imodzi pachaka ya CO₂ mpweya wotulutsa mpweya wachepetsedwa ndi ~ matani 45 pa 50,000 kWh yopulumutsidwa
• Zolimbikitsa: Zimagwirizana ndi zaku China Maupangiri Owunika Kusunga Mphamvu Zamagetsi, oyenera kulandira thandizo laukadaulo wobiriwira

 IV. Nkhani Yophunzira: Petrochemical Enterprise Multistage Pump Group Retrofit

4.1 Mbiri Yoyambira

• Vuto: Kuyimitsidwa pafupipafupi kwa mapampu otumizira mafuta osapsa kumapangitsa kuti pakhale ndalama zokonzekera pachaka >$109,832 chifukwa dongosolo kusinthasintha kwamphamvu
• Yankho: Kuyika ma VFD a 3 × 315 kW okhala ndi masensa amphamvu ndi nsanja yowunikira mitambo

4.2 Zotsatira za Kukhazikitsa

• Miyezo ya mphamvu: Kugwiritsa ntchito mphamvu pa pampu pa pampu kuchepetsedwa kuchoka pa 210 kW kufika pa 145 kW, mphamvu zamakina zakwera ndi 32%
• Ndalama zogwirira ntchito: Kulephera kwanthawi yayitali kunatsika ndi 75%, ndalama zosamalira pachaka zimachepetsedwa$27,458.
• Phindu lazachuma: Ndalama zobwezeredwa zonse zabwezedwa mkati mwa zaka 2, phindu lonse >$164,749

V. Tsogolo la Tsogolo ndi Malingaliro

1. Kukweza Mwanzeru: Kuphatikiza kwa ma algorithms a IoT ndi AI pakuwongolera mphamvu zolosera

2. Mapulogalamu Opanikizika Kwambiri: Kupanga ma VFD oyenera mapampu a 10 kV+ multistage

3. Kuwongolera kwa moyo: Kukhazikitsidwa kwa mitundu iwiri yamapasa ya digito kuti muthe kukhathamiritsa moyo wabwinobwino

Kutsiliza
Makina owongolera liwiro osinthika amakwaniritsa kusintha kwamphamvu kwamphamvu komanso kutsika mtengo kwamapampu amagetsi osunthika ambiri pofananiza ndendende zomwe zimafunikira pamutu. Kafukufuku waposachedwa akuwonetsa nthawi yobwezera yazaka 1-3 yokhala ndi phindu lalikulu pazachuma komanso chilengedwe. Ndikupita patsogolo kwa digito ya mafakitale, ukadaulo wa VFS ukhalabe yankho lalikulu pakukhathamiritsa kwamphamvu kwapampu.
