Koj puas paub yuav ua li cas xaiv cov inverter rau lub teeb thauj thiab lub nra hnyav?

Koj puas paub xaiv lubinverterRau lub teeb thauj thiab thauj khoom hnyav?

Nyob rau hauv cov txheej txheem ntawm inverter xaiv, lub teeb thauj thiab lub nra hnyav yog ob lub tswv yim tseem ceeb. Kev nkag siab zoo thiab pom qhov tshwj xeeb no ob hom kev thauj khoom yog qhov tseem ceeb los xaiv txoj cai inverter!

1. Dab tsi yog lub teeb thauj khoom?

Lub teeb lo tau txhais tau hais tias lub zog tsim nyog los ntawm cov khoom siv thaum lub sijhawm ua haujlwm me me, thiab nws yuav tsis ua rau lub siab loj ntawm cov inverter.

Cov khoom siv hluav taws xob teeb hluav taws xob cov khoom siv xws li cov dej kiv cua, thiab lwm yam, nws lub zog. Raws li kev ua haujlwm ib txwm muaj, cov cua tsis zoo ntawm cov kiv cua tuaj yeem yog qhov me me, thiab cov tsav tsheb uas xav tau tsis loj.

Ib qho ntxiv, cov txheej txheem pib ntawm hom khoom siv no yog qhov zoo li, thiab inverter tsis tas yuav muab ntau qhov pib ua kom muaj zog ntau dhau. Nyob rau hauv lub teeb ntsaws cov kev mob, cov kev khiav hauj lwm tam sim no ntawm inverter feem ntau yog tsawg dua lossis qis dua 50% ntawm qhov muaj peev xwm ntawm lub inverter tsis yog siab.

Yog li ntawd, rau cov khoom siv hluav taws xob teeb, thaum xaiv cov inverter, nws tuaj yeem sib phim raws li lub zog ntawm lub cev muaj zog, thiab feem ntau tsis tas yuav muaj peev xwm nce lub peev xwm ntawm inverter.

Cov yam ntxwv ntawm Lub Teeb Cov Khoom Siv:

• Lub load torque nce nrawm nrog kev nce ntawm kev ceev.
• Thaum khiav ntawm kev nrawm nrawm, lub nra torque yog me me.
• Haum rau inverter lub teeb thauj (lo) xaiv fais fab.
• Inverter tam sim no yog me me thaum ua haujlwm.

2. Dab tsi yog lub nra hnyav?

Cov thauj khoom hnyav txhais tau tias cov cuab yeej xav tau cov torque loj thaum khiav, thiab ntau zaus yuav tshwm sim. Cov khoom hnyav hnyav-thauj khoom suav nrog Cranes, Rolling mills, siv conveyors, thiab lwm yam.

Piv txwv li, thaum nqa khoom hnyav, cranes yuav tsum tsis yog tsuas yog ua rau lub ntiajteb txawj nqus ntawm cov khoom hnyav, tab sis kuj tseem xav tau lub zog loj. Thaum lub sijhawm ua haujlwm, vim kev hloov pauv hauv kev thauj khoom (xws li viav vias ntawm cov khoom hnyav, hloov pauv ntawm lub cev muaj zog yuav hloov zoo heev, lossis txawm ntau dhau.

Cov khoom siv hnyav-thauj khoom muaj lub siab rau cov inverters, uas xav tau cov invereers kom muaj zog tshaj lub peev xwm hauv lub sijhawm luv luv kom tau raws li cov khoom siv ua haujlwm.

Feem ntau hais lus, inverter xaiv rau cov khoom siv hnyav thauj khoom yuav tsum xav txog 1.5 zaug lossis ntau dua ntawm lub cev muaj zog tam sim no kom ntseeg tau tias cov inverter tuaj yeem ua haujlwm ruaj khov nyob rau hauv ntau yam kev ua haujlwm.

Cov yam ntxwv ntawm hnyav-thauj khoom siv:

• Lub nra torque tseem tsis hloov pauv thaum tag nrho cov txheej txheem ua haujlwm.
• Yuav tsum muaj qhov loj dua lub zog.
• Haum rau inverter hnyav-thauj khoom (ho) xaiv fais fab.
• Inverter tam sim no yog loj thaum lub sijhawm ua haujlwm.

Feem ntau hais lus, cov txheeb ze ntawm tsis muaj-lub teeb-thau khoom, hnyav-thauj, puv-thauj khoom thiab tshaj tawm tuaj yeem txawv raws li cov hauv qab no:
Tsis muaj-thauj 0%;
Lub teeb thauj tsawg dua 30%;
Hnyav load 80% -100%;
Tag nrho load 100%;
Overload loj dua 100%.
