Yuav ua li cas txo qis zog poob hauv lub cev muaj zog ua haujlwm

Yuav ua li cas txo qis zog poob hauv lub cev muaj zog ua haujlwm

Txhawm rau txo qis zog hauv kev ua haujlwm ntawm lub cev muaj zog, kev ntsuas dav yuav tsum tau ua nyob rau hauv ntau qhov ntev, suav nrog kev tsim thiab xaiv, kev tswj xyuas kev ua haujlwm, thiab kev tswj xyuas. Raws li cov ntaub ntawv tshaj tawm tshaj tawm rau pej xeem txij li xyoo 2026, cov kev ntsuas tseem ceeb yog raws li hauv qab no:

1, Optimize lub efficiency ntawm lub cev muaj zog

Xaiv lub siab-cov motors ua tau zoo: Qhov tseem ceeb yuav tsum tau muab rau cov motors uas ua tau raws li qib kev siv hluav taws xob ntawm IE3, IE4, lossis IE5 (raws li lub teb chaws tus qauv GB 18613-2020), hloov cov qub thiab tsis muaj zog motors (xws li IE1 lossis E-chav insulated motors)

Kev siv cov khoom siv ua haujlwm siab -:

Txo cov hlau poob los ntawm kev siv cov ntawv txias-silicon steel dov (xws li qib siab- qib silicon steel);

Hloov cam khwb cia txhuas rotors nrog tooj liab rotors tuaj yeem txo rotor poob los ntawm 10% mus rau 15%

Siv cov hlau nplaum qhov sib nqus los yog cov av nplaum sib nqus kom txo qis kev poob mus txog 60%

Optimize structural tsim:

Shortening qhov ntev ntawm stator winding kawg tuaj yeem txo qhov poob li ntawm 10%

Txais sine winding, skewed groove los yog luv luv winding los suppress siab - txiav txim harmonics thiab txo stray losses

Rau siab - lub cev muaj zog, txo cov kiv cua loj lossis ua kom lub qhov cua kom zoo tuaj yeem txo qhov kev sib txhuam cua (suav txog li 25% ntawm tag nrho cov poob)

2, Match load thiab ua haujlwm hom

Tsis txhob "tus nees loj rub lub tsheb me": xyuas kom meej tias lub cev muaj zog load tus nqi yog nyob rau hauv kev lag luam kev lag luam ntawm 70% ~ 100%, thiab zam lub sijhawm ntev - lub teeb load (<40%) operation

Kev siv cov cuab yeej siv hluav taws xob sib txawv sib txawv: haum rau cov khoom siv thauj khoom sib txawv xws li kiv cua thiab cov twj tso dej. Los ntawm kev kho qhov ceev kom phim cov kev xav tau tiag tiag, lub zog -txuag tus nqi tuaj yeem ncav cuag 20% ​​~ 50%; Tshwj xeeb tshaj yog ntawm 80% ntsuas kev ua haujlwm ceev, txuag hluav taws xob ze li 40%

Lub teeb load voltage txo kev ua haujlwm: Rau squirrel tawb asynchronous motors, txoj kev sib txuas tuaj yeem hloov pauv los ntawm Δ mus rau Y nyob rau hauv lub teeb load, thiab qhov ua tau zoo tuaj yeem txhim kho mus rau 79.7% (keeb kwm 66.7%)

Reactive fais fab nyiaj them: Txuas cov capacitors nyob rau hauv parallel ntawm qhov chaw kom nce lub hwj chim mus rau 0.9 ~ 0.96 thiab txo qis zog poob hauv kab

3, System theem zog-txuag ntsuas

Regenerative braking zog rov qab: Hauv cov khoom siv xws li elevators thiab cranes, lub zog kinetic generated thaum lub sij hawm deceleration yog hloov dua siab tshiab rau hauv hluav taws xob zog thiab pub rov qab rau hauv daim phiaj fais fab.

Kev tswj hwm kev txawj ntse: Los ntawm kev saib xyuas cov khoom thauj hauv lub sijhawm tiag tiag thiab hloov kho qhov voltage, zaus, lossis cov naj npawb ntawm cov units, lub cev muaj zog ib txwm ua haujlwm hauv qhov siab - ua haujlwm tau zoo

Multi motor linkage control: dynamically pib thiab nres lub cev muaj zog raws li tag nrho cov load xav tau kom tsis txhob idling los yog tsis ua hauj lwm

4, Txhim khu kev txij nkawm thiab kev tswj xyuas

Kev saib xyuas tsis tu ncua: cov cua huv huv, lubricate bearings, xyuas cov rwb thaiv tsev thiab hluav taws xob sib txuas, tswj kev ua haujlwm zoo

Kev tswj ib puag ncig: Khaws qhov cua kom zoo thiab qhov kub thiab txias (tsis txhob overheating) los tiv thaiv kev laus ntawm rwb thaiv tsev thiab nce kev poob

Kev saib xyuas kev siv hluav taws xob: Nruab lub ntsuas hluav taws xob thiab cov ntsuas hluav taws xob, ua qhov ntsuas kev siv hluav taws xob, thiab txheeb xyuas lub zog- txuag lub peev xwm.

5, Txoj cai thiab kev txhawb nqa technology

Lub teb chaws tus qauv GB 30253-2024 tau ua tiav thaum Lub Kaum Hli 2025, uas tso siab rau cov kev xav tau siab dua rau kev siv zog ntawm cov hlau nplaum ruaj khov synchronous motors

Ntau cheeb tsam (xws li Shanghai) muab kev pab nyiaj rau kev yuav khoom ntawm IE4/IE5 motors kom ceev zog-txuag renovation

Summary suggestion:

Rau cov haujlwm tshiab lossis cov khoom tseem ceeb xws li cov kiv cua thiab cov twj tso kua mis, qhov kev sib xyaw ua ke zoo tshaj plaws yog siab -cov motors ua haujlwm tau zoo thiab qhov sib txawv ntawm kev ceev ceev; Rau cov txheej txheem qub, yuav tsum tau muab qhov tseem ceeb rau kev hloov siab - lub cev muaj zog ua haujlwm tau zoo thiab txhim kho cov khoom siv hluav taws xob reactive lossis zaus hloov pauv. Los ntawm kev sib txuas nrog kev saib xyuas tsis tu ncua nrog kev tswj hwm ntse, kev siv hluav taws xob tuaj yeem txo qis, thiab lub sijhawm peev nyiaj rov qab feem ntau yog 1-3 xyoos.

 

500W lub cev muaj zog-cov lus qhia txuag

1, Lub Zog Siv Qhov Tseeb ntawm 500W Tsav

Lub cev muaj zog 500W zoo li lub cav 1.5L hauv lub tsheb: nws tsis muaj hwj chim ntau tab sis txaus. Nws lub hwj chim noj yeej nyob ntawm peb lub ntsiab lus tseem ceeb:

Tsis muaj load poob: tseem siv 15% -20% ntawm hluav taws xob thaum tsis muaj load

Load matching: Efficiency tsuas yog 60% nyob rau hauv lub teeb load, thiab muaj peev xwm ncav cuag 85% nyob rau hauv tag nrho load

Ceev nkhaus: Thaum tus tsim ceev tshaj, lub zog noj yuav nce exponentially

2, Kev txawj ntse daws teeb meem kom txuag hluav taws xob tsis ua kom qeeb

Los ntawm optimizing kev siv, nws yog kiag li ua tau kom txuag tau hwj chim thaum tswj ceev:

Load tswj: Tsis txhob khiav qis dua 30% load rau lub sijhawm ntev

Thaum tshav kub kub dissipation optimization: Rau txhua txhua 10℃txo qhov kub nce, efficiency nce 2%

Pulse tswj: Kev ua haujlwm tsis tu ncua tuaj yeem txuag tau 25% hluav taws xob

Lubrication txij nkawm: zoo lubrication txo kev sib txhuam los ntawm 10%.

Qhov teeb meem ntawm kev siv hluav taws xob ntawm hluav taws xob motors yog multifaceted thiab yuav tsum tau ua tib zoo tsom xam thiab kev xav zoo. Ua ntej, tus nqi thauj khoom ntawm lub tshuab hluav taws xob feem ntau yog qis, feem ntau yog vim kev xaiv lub cev muaj zog lossis kev hloov pauv hauv cov txheej txheem ntau lawm. Hauv kev ua haujlwm zoo, peb feem ntau pom tias li 30% txog 40% ntawm cov tshuab hluav taws xob ua haujlwm ntawm 30% mus rau 50% ntawm lawv cov khoom ntsuas, thiab qhov kev ua haujlwm tsis zoo no yuav ua rau muaj kev siv zog ntxiv.

Qhov thib ob, qhov teeb meem ntawm cov khoom siv hluav taws xob hluav taws xob kuj yog ib qho tseem ceeb hauv kev siv hluav taws xob ntawm hluav taws xob motors. Hauv peb-theem plaub xaim qis-voltage fais fab mov system, qhov tsis sib xws ntawm ib zaug -theem loads feem ntau ua rau asymmetric peb-theem voltages ntawm lub cev muaj zog, ua rau tsis zoo ib ntus torque thiab nce kev khiav hauj lwm poob ntawm lub cev muaj zog. Tsis tas li ntawd, ntev - lub sij hawm tsis tshua muaj hluav taws xob hluav taws xob kuj tuaj yeem ua rau lub cev muaj zog tam sim no tsis zoo, ua rau poob ntxiv. Qhov kev poob no nce nrog qhov nce ntawm peb -theem voltage asymmetry thiab txo qhov voltage.

Tsis tas li ntawd, qee lub cav qub lossis cov qub qub tseem siv tau, feem ntau siv E-chav rwb thaiv tsev, uas yog loj, muaj kev ua haujlwm tsis zoo, thiab kev ua haujlwm qis. Txawm hais tias qee qhov kev hloov kho tau ua nyob rau hauv xyoo tas los no, cov motors no tseem siv tau rau qee qhov chaw, uas tsis muaj qhov xav tau nce kev siv zog.

Thaum kawg, qhov teeb meem ntawm kev tswj xyuas tsis tuaj yeem tsis quav ntsej. Qee chav nyob tsis txuas qhov tseem ceeb txaus rau kev saib xyuas thiab tu cov motors thiab khoom siv. Nyob rau tib lub sijhawm, tsis tsuas yog kev ua haujlwm ntawm cov cuab yeej yuav txo qis, tab sis qhov hnav thiab tsim kua muag kuj tseem yuav nce ntxiv.

Yog li ntawd, hauv kev teb rau cov teeb meem kev siv hluav taws xob tau hais los saum no, peb yuav tsum ua hauv - tshawb fawb tob thiab xaiv lub zog tsim nyog - txuag cov kev daws teeb meem. Piv txwv li, peb tuaj yeem txo qhov kev siv hluav taws xob ntawm lub tshuab hluav taws xob zoo, ua tiav kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig los ntawm kev xaiv lub cev muaj zog, txhim kho lub zog zoo, hloov kho cov qub motors, thiab ntxiv dag zog rau kev tswj xyuas.

Qhov txuas hauv qab no yog peb lub zog txuag hluav taws xob txuas:
