The working principle of one-to-two induction melting rauv

Kev ua haujlwm hom txais ib-rau-ob, ib-rau-ob txhais tau hais tias ib txheej ntawm rectifier fais fab mov tsav kev ua haujlwm ntawm ob pawg ntawm inverter li.

Ua haujlwm ntawm nws tus kheej nrog txhua txheej ntawm inverter ntaus ntawv, muab lub zog rau lub cub tawg A lossis rauv B, nrog rau ob lub zog thiab ib qho rau ob txoj haujlwm, tshwj xeeb tshaj yog

Haum rau kev lag luam loj loj nruam ntau lawm ntawm me me thiab nruab nrab-qhov loj me castings, ib qho hluav taws xob rauv hluav taws xob muaj zog melting lag luam, lwm lub cub tawg.

Lub cev tuaj yeem khaws cia sov lossis cov khoom txias tuaj yeem ua rau preheated, thiab lub zog tuaj yeem faib raws li qhov xav tau. Tag nrho lub zog ntawm ob lub cub hluav taws xob yog tas li.

Ntawd yog, tag nrho lub zog P tag nrho = PA + PB

Ob lub qhov cub hluav taws xob tsis tu ncua hloov pauv thiab ua kom sov rau casting thaum khiav tib lub sijhawm, kom lub zog hluav taws xob tuaj yeem ua haujlwm ntawm lub zog tag nrho.

OK, txhawm rau txhim kho cov khoom tsim hluav taws xob melting ntawm lub cub hluav taws xob, daim duab qhia tau hais tias ib-rau-ob induction melting rauv.

Schematic daim duab ntawm ib-rau-ob induction melting rauv

Thaum lub series inverter fais fab mov ua hauj lwm, lub rectifier ib txwm ua hauj lwm nyob rau hauv tag nrho cov conduction, hloov lub tso zis hwj chim ntawm lub inverter voj.

Nws yog tiav los ntawm kev tswj cov zaus ntawm inverter trigger mem tes. Thiab lub load tam sim no yog sine yoj, yog li lub zog inverter txuas nrog hauv series

Yuav tsis muaj qhov kev txiav txim siab sib haum xeeb uas ua rau muaj kuab paug rau hauv daim phiaj hluav taws xob, thiab lub zog muaj zog yog siab. Parallel inverters tsis tuaj yeem ua tiav ib-rau-ob tus kheej

Dynamic fais fab kev hloov kho, vim hais tias lub hwj chim hloov ntawm lub parallel inverter fais fab mov tuaj yeem ua tiav los ntawm kev kho cov zis voltage ntawm tus choj rectifier.

Thaum lub inverter rectifier choj ua haujlwm ntawm qhov tsis tshua muaj hluav taws xob thiab lub kaum sab xis rectifier yog qhov me me, lub zog ntawm cov khoom siv yuav tsawg heev.

Thiab thaum uas tig mus inverter load tam sim no yog ib lub xwmfab yoj, uas yuav ua phem rau daim phiaj. Yog tias lub zog hloov kho los ntawm kev kho lub inverter rov qab siab lub kaum sab xis,

Lub zog hloov kho ntau yam yog nqaim heev, yog li cov khoom siv hluav taws xob sib txuas tsis tuaj yeem ua tiav ib-tsav-ob txoj haujlwm.
