Txoj kev kho ntawm induction melting rauv

1. Thaum lub qhov cub induction melting ua tsis tiav, nws yuav tsum tau saib xyuas seb qhov ntsuas qhov ntsuas ntawm qhov induction melting rauv yog qhov tseeb thaum nws khiav, thiab seb puas muaj cua sov, liab, xoob screws thiab lwm yam tshwm sim hauv induction melting. rauv. Txawm hais tias kev sib raug zoo ntawm qhov nruab nrab zaus voltage, DC voltage, thiab DC tam sim no ntawm induction melting furnace meter yog ua haujlwm ib txwm. Cov khoom ntawm DC voltage thiab DC tam sim no yog lub zog nruab nrab zaus, yog li peb tuaj yeem txiav txim siab seb lub zog ntawm qhov cub induction melting yog qhov qub; seb qhov piv ntawm cov kab hluav taws xob nkag, DC voltage thiab nruab nrab zaus voltage yog qhov tseeb. Piv txwv li: 500kw induction melting rauv, cov kab hluav taws xob tuaj yog 380V, ces qhov siab tshaj plaws DC voltage yog 513V, thiab DC tam sim no yog 1000A. Yog tias qhov hluav taws xob DC nce mus txog 500V thiab DC tam sim no tus nqi yog 1000A thaum lub sijhawm ua haujlwm, lub zog ua haujlwm yog qhov qub. Qhov piv ntawm DC voltage thiab nruab nrab zaus voltage tuaj yeem cuam tshuam txog kev ua haujlwm ntawm lub inverter. Piv txwv li, yog tias DC voltage yog 510V thiab qhov nruab nrab zaus voltage yog 700V, lub kaum sab xis ntawm lub inverter yog 36 °. Peb siv 700V / 510V = 1.37 kom pom tias, feem ntau, qhov sib piv ntawm qhov nruab nrab zaus voltage thiab DC voltage yog nyob nruab nrab ntawm 1.2 thiab 1.5, thiab peb txhua tus xav tias lub inverter ua haujlwm ib txwm. Yog tias qhov sib piv tsawg dua 1.2, lub kaum sab xis ntawm cov hlau lead me me dhau, thiab lub inverter nyuaj rau kev sib hloov; Yog tias nws loj dua 1.5 npaug, lub kaum sab xis txhuas loj dhau, thiab cov khoom siv yuav ua tsis tiav.

2. Txawm hais tias lub suab ntawm induction melting rauv yog qhov qub thaum lub sijhawm ua haujlwm, txawm tias muaj suab nrov hauv lub suab ntawm lub induction melting rauv, seb lub suab txuas ntxiv mus, seb puas muaj lub suab nrov reactor vibration thiab seb puas muaj lub suab nrov ntawm lub tshuab hluav taws xob. ignition, thiab lwm yam. Nyob rau hauv luv luv, nws yog txawv los ntawm ib txwm suab. los txiav txim lub suab txoj hauj lwm.

3. Nug tus neeg teb xov tooj ntawm induction melting rauv txog qhov xwm txheej ntawm lub qhov cub induction melting thaum nws tawg. Thaum nkag siab nws, sim ua kom ntxaws li sai tau. Nyob rau tib lub sijhawm, koj yuav tsum nkag siab txog cov xwm txheej ntawm kev ua haujlwm ntawm induction melting rauv ua ntej qhov tsis ua haujlwm.

4. Thaum lub qhov cub induction melting tsis ua haujlwm, koj yuav tsum kawm siv cov cuab yeej ntsuas xws li oscilloscopes thiab multimeters los ntsuas qhov waveform, voltage, lub sij hawm, lub kaum ntse ntse, tsis kam thiab lwm yam ntawm txhua qhov taw tes los txiav txim qhov ua tsis tiav.

5. Yog tias qhov txhaum ntawm lub qhov cub induction melting tau pom thiab kho, tsis txhob khiav cov khoom siv ncaj qha tom qab pom qhov txhaum tsis muaj kev tshuaj ntsuam xyuas, vim tias feem ntau muaj lwm cov laj thawj sib sib zog nqus tom qab qhov txhaum taw tes ua rau muaj qhov tsis raug.
