Dị ka ngwa ụgbọ njem mmiri na-arụ ọrụ nke ọma nke a na-ejikarị na ọrụ nchekwa mmiri, ụlọ ọrụ petrochemical, na sistem mmiri na-enye mmiri n'obodo mepere emepe, nfuli igwe kwụ otu ebe kwụ ọtọ na-akwụ ụgwọ maka 30%-50% nke ngụkọta ike sistemu. Ụzọ njikwa ọsọ ọsọ nke ọdịnala ọdịnala na-ata ahụhụ site na mkpofu ume n'ihi enweghị ike imekọ ihe achọrọ n'ike. Site na ntozu oke nke teknụzụ njikwa ọsọ ọsọ (VFS), ngwa ya na-echekwa ike maka  multistage vetikal turbine nfuli  aghọwo isi ihe na ụlọ ọrụ. Akwụkwọ a na-enyocha uru bụ isi nke sistemu VFS site na ụkpụrụ teknụzụ, mmetụta nchekwa ike bara uru, na echiche akụ na ụba.

I. Usoro nka na ngbanwe nke sistemu njikwa ọsọ ọsọ na-agbanwe agbanwe ka ọ bụrụ nfuli turbine kwụ ọtọ.

1.1 Ụkpụrụ bụ isi nke njikwa ọsọ ọsọ na-agbanwe agbanwe

Sistemụ VFS na-edozi oge ọkọnọ ike moto (0.5-400 Hz) iji mezie ọsọ mgbapụta (N∝f), si otú a na-achịkwa ọnụego eruba (Q∝N³) na isi (H∝N²). Ndị na-ahụ maka isi (dịka, VFDs) na-eji algọridim PID maka njikwa nrụnye ziri ezi site na ngbanwe ugboro ugboro.

1.2 Njirimara arụmọrụ nke Pumps Turbine Multistage vetikal yana ndakọrịta na VFS

Key featuresinclude:

• Oke arụmọrụ dị elu dị warara: Ọ na-adịkarị mfe ọdịda arụmọrụ mgbe ọ na-arụ ọrụ n'ebe dịpụrụ adịpụ

• Large flow fluctuations: Require frequent speed adjustment or start-stop operations due to system pressure variations

• Ogologo nhazi nhazi ogologo: valvụ ọdịnala na-akpata ọnwụ ike na nsogbu ịma jijiji

VFS na-edozi ọsọ ọsọ ozugbo iji gboo ihe achọrọ, na-ezere mpaghara arụ ọrụ dị ala ma na-emeziwanye arụmọrụ sistemụ.

II. Ntụle arụmọrụ nke nchekwa ike nke sistemu njikwa ọsọ ọsọ na-agbanwe agbanwe

2.1 Isi usoro maka nkwalite arụmọrụ ike

(Where ΔPvalve represents valve throttling pressure loss)

2.2 Data Okwu Ngwa bara uru

• ** Ọrụ Mweghachi nke Osisi Na-eweta Mmiri:**

· Equipment: 3 XBC300-450 multistage vertical pumps (155 kW each)

· Before Retrofit: Daily electricity consumption ≈ 4,200 kWh, annual cost ≈$39,800

· After Retrofit: Daily consumption reduced to 2,800 kWh, annual savings ≈$24,163, payback period < 2 years

III. Ntụle akụ na ụba na nyocha nlọghachi ego

3.1 Ntụle ọnụ n'etiti ụzọ njikwa

3.2 Mgbakọ oge ịkwụghachi ego itinye ego

Example: Equipment cost increase$27,458, annual savings$24,163 → ROI ≈ 1.14 years

3.3 Uru akụ na ụba ezoro ezo

• Ogologo ndụ akụrụngwa agbatịkwuru: 30% -50% ogologo mmezi okirikiri n'ihi mbelata ịdị arọ

• Mbelata ikuku carbon: Otu mgbapụta ikuku CO₂ kwa afọ belatara site na ~ 45 tọn kwa 50,000 kWh echekwara

• Policy incentives: Compliant with China's Industrial Energy Conservation Diagnosis Guidelines, eligible for green tech subsidies

IV. Ọmụmụ ihe: Petrochemical Enterprise Multistage Pump Group Retrofit

4.1 Backlọ Ọrụ

• Problem: Frequent start-stop of crude oil transfer pumps caused annual maintenance costs >$109,832 due to system pressure fluctuations

• Ngwọta: Ntinye nke 3 × 315 kW VFD na ihe mmetụta nrụgide na ikpo okwu nlekota igwe ojii

4.2 Nsonaazụ mmejuputa

• Metrik ike: ike mgbapụta ọ bụla na-ebelata site na 210 kW ruo 145 kW, arụmọrụ usoro na-emeziwanye site na 32%

• Operational costs: Failure downtime decreased by 75%, annual maintenance costs reduced to$27,458.

• Economic benefits: Full retrofit cost recovered within 2 years, cumulative net profit >$164,749

V. Ọdịnihu na Aro aro

1. Intelligent Upgrades: Integration of IoT and AI algorithms for predictive energy control

2. High-Pressure Applications:  Development of VFDs suitable for 10 kV+ multistage pumps

3. Njikwa okirikiri ndụ: Establishment of digital twin models for energy-efficient lifecycle optimization
