Peb -Phase Asynchronous Motor Selection Guide: 4 Cov Ntsiab Cai Tseem Ceeb Kom Tsis txhob xaiv qhov yuam kev

Nyob rau hauv industrial ntau lawm, xaiv ntawmpeb -theem asynchronous motorsncaj qha cuam tshuam rau kev tsim khoom, kev siv hluav taws xob tswj thiab khoom siv lub neej. Txawm li cas los xij, ntau lub lag luam yooj yim poob rau hauv kev nkag siab tsis zoo xws li "qhov loj dua lub zog, qhov zoo dua" thiab "universal qauv" thaum lub sij hawm xaiv, ua rau cov khoom siv khib nyiab, kev siv hluav taws xob ntau thiab kev ua tsis tiav. Yog li ntawd, ua ke nrog kev lag luam kev ua haujlwm, peb tau txheeb xyuas 4 lub hauv paus ntsiab lus rau kev xaivpeb -theem asynchronous motorslos pab cov tuam txhab xaiv cov qauv kom raug, txo cov nqi thiab nce kev ua haujlwm zoo.

Lub hauv paus ntsiab lus 1: Load Matching, tshem tawm "Oversized Motor for Light Load". Lub hauv paus ntawm kev xaiv yog xaiv lub cev muaj zog uas muaj peev xwm ua tau raws li lub zog, ceev thiab lub zog ntawm cov khoom siv thauj khoom, kom tsis txhob muaj hluav taws xob pov tseg los ntawm lub cev muaj zog ntau dhau, lossis cov khoom siv ua haujlwm luv luv los ntawm kev ua haujlwm ntev - lub sijhawm ua haujlwm dhau vim muaj peev xwm tsis txaus. Piv txwv li, rau lub teeb- cov khoom siv thauj khoom xws li kiv cua thiab cov twj tso kua dej, lub cev muaj zog nrog lub zog ntsuas me ntsis siab dua qhov kev thauj khoom tuaj yeem xaiv tau; rau hnyav- cov khoom siv thauj khoom xws li cov tshuab mining thiab cov cuab yeej siv tshuab, lub peev xwm tshaj ntawm lub cev yuav tsum raug txiav txim siab, thiab cov khoom uas muaj ntau tshaj 1.5-2 zaug yuav tsum nyiam.

Lub hauv paus ntsiab lus tseem ceeb 2: Hloov mus rau hom pib, txo hwj chim daim phiaj cuam tshuam. Cov xwm txheej sib txawv muaj qhov xav tau sib txawv rau cov qauv pib lub cev muaj zog. Cage motors muaj cov qauv yooj yim thiab tus nqi qis, haum rau kev pib ncaj qha lossis lub hnub qub -delta pib, thiab hloov mus rau cov xwm txheej nrog lub teeb load thiab qis pib zaus; qhov txhab-rotor motors, zoo ib yam li stator windings, tuaj yeem ua tiav muag pib los ntawm kev sib txuas cov resistors lossis zaus-rheostats nyob rau hauv lub rotor, zoo txo ​​qhov cuam tshuam ntawm kev pib tam sim no ntawm daim phiaj fais fab, thiab tsim nyog rau hnyav-load thiab nquag pib scenarios, xws li mining hoists, loj conveyors.

Lub hauv paus ntsiab lus 3: Muab cov kev cai ceev ceev, hloov mus rau txheej txheem ntau lawm. Yog tias ntau- yuav tsum tau ua haujlwm ceev hauv cov txheej txheem tsim khoom, xws li cov kab ntau lawm kev tswj ceev thiab kev hloov pauv huab cua, ib qho - winding multi- ceev motors los yog hloov pauv - zaus tswj lub cev muaj zog tuaj yeem xaiv tau. Stepless ceev txoj cai tuaj yeem pom tau los ntawm kev siv tshuab hloov pauv zaus, uas tsis tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem yooj yim, tab sis tseem txo qis kev siv hluav taws xob ntxiv - hauv cov kiv cua thiab cov twj tso kua dej, kev hloov pauv ceev ceev yuav txuag tau ntau dua 30% ntawm lub zog hluav taws xob. Yog tias tsis tas yuav muaj kev tswj hwm kev ceev, kev ruaj ntseg zoo tib yam - zauspeb -theem asynchronous motorstuaj yeem raug xaiv los txo cov nqi yuav khoom.

Lub hauv paus ntsiab lus 4: Kho kom haum rau ib puag ncig kev pabcuam, ua kom muaj kev ntseeg siab. Kev pabcuam ib puag ncig ntawm kev lag luam sib txawv txawv heev. Nws yog ib qho tsim nyog los xaiv cov qib kev tiv thaiv thiab qib rwb thaiv tsev raws li yam xws li ib puag ncig cov av noo, kub, plua plav thiab corrosiveness. Piv txwv li, nyob rau hauv ib puag ncig hnyav nrog ntau plua plav thiab av noo xws li tshuaj lom neeg kev lag luam thiab mining, motors nrog IP55 thiab siab dua qib tiv thaiv, F-level lossis H- qib rwb thaiv tsev yuav tsum raug xaiv; rau ib puag ncig kev cob qhia zoo tib yam, IP44 kev tiv thaiv qib tuaj yeem ua tau raws li qhov xav tau, zam lub cev muaj zog luv luv thiab kev puas tsuaj los ntawm kev hloov pauv ib puag ncig tsis zoo.

Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau lub zog efficiency ntawm lub cev muaj zog thaum xaiv. Qhov tseem ceeb yuav tsum tau muab rau IE3 thiab siab dua -kev ua tau zoo thiab lub zog- txuag lub cev muaj zog, uas yog raws li cov cai ntawm "Motor Energy Efficiency Improvement Plan (2023-2025)". Lawv tsis tuaj yeem txo cov nqi siv hluav taws xob nkaus xwb, tab sis kuj ua raws li txoj cai tswjfwm kom ua tiav kev tsim khoom ntsuab.
