Technical yam ntxwv ntawm induction melting rauv, kev ceev faj rau kev siv, kev tu thiab kev kho mob xwm txheej ceev

Cia kuv qhia rau sawv daws.

A. Kev ceev faj rau kev siv ntawm induction melting rauv

1. Xyuas seb tag nrho cov khoom puas zoo;

2. Xyuas seb tag nrho cov fasteners puas zoo;

3. Xyuas seb tag nrho cov kev sib txuas puas tau poob, thiab seb cov pob qij txha puas yog unsoldered;

4. Xyuas seb qhov kev sib txuas hauv kev teeb tsa puas yog;

5. Siv lub tshuab multimeter los xyuas lub ntsiab Circuit Court, rwb thaiv tsev ntawm lub casing thiab rwb thaiv tsev ntawm cov theem ntawm kev tswj Circuit Court;

6. Tshawb xyuas seb qhov kev tswj xyuas plug-in puas tau muab tso rau hauv txoj haujlwm raug;

7. Qhib cov dej nkag valve, kho cov dej siab mus rau 0.1 ~ 0.2Mpa, thiab xyuas seb puas muaj cov dej xau hauv txhua txoj kev;

8. Ua tib zoo xyuas cov theem ua ntu zus, lub qhov cub smelting yog 120 ° ua ntej ntawm lub sijhawm nruab nrab ntawm lub zog hluav taws xob, thiab lub qhov cub tuav yog 120 ° tom qab lub zog nruab nrab zaus;

9. Nias qhov kev tswj thiab lub hwj chim hloov, lub hwj chim taw qhia ntawm txhua lub vaj huam sib luag yuav tsum nyob rau;

10. Siv lub oscilloscope los xyuas seb qhov ua rau cov pulses ntawm rectification thiab inverter yuav tsum zoo li qub;

11. Cov kev tiv thaiv thyristor tau tshwm sim, thiab cov cim tiv thaiv sib raug teeb pom kev;

12. Teem lub hwj chim hloov potentiometer mus rau txoj hauj lwm 0, rub tawm lub rooj tsav xwm tswj, thiab xyuas tias qhov kev txiav txim relay yuav tsum zoo li qub. Rau

B. Cov yam ntxwv ntawm induction melting rauv

Lub induction melting rauv adopts “series inverter thyristor nruab nrab zaus fais fab mov tshuab”. Txawm hais tias lub thyristor tag nrho tswj rectifier hluav taws xob rauv yog siv, nws tsis siv nws los kho qhov voltage. Nws tsuas yog siv nws kom ua tiav qhov pib muag muag thiab ua raws li kev hloov hluav taws xob hauv qhov xwm txheej tsis ua haujlwm sai sai txiav tawm lub zog hluav taws xob. Thaum ua hauj lwm, thyristor yog ib txwm nyob rau hauv ib tug tag nrho conductive lub xeev, yog li hais tias daim phiaj fais fab mov muaj ib tug siab zog yam tseem ceeb thiab txo harmonic cuam tshuam. Lub rectifier tswj Circuit Court txais yuav ib qho kev hloov pauv digital. Cov kev hloov pauv digital muaj qhov zoo ntawm qhov rov ua tau zoo, kev ruaj ntseg zoo, zoo sib xws, muaj peev xwm tiv thaiv kev cuam tshuam, thiab yooj yim debugging. Yog tias qhov kev teeb tsa digital tau txais yuav, nws tseem tuaj yeem paub cov chaw taws teeb tswj. Nyob rau hauv tas li ntawd, lub induction melting rauv yog ib tug melting rauv nrog ntau zog. Yog li ntawd, txhawm rau ua kom nws lub zog siab tshaj plaws, peb yuav tsum tau them sai sai rau qee qhov kev siv ceev faj thiab nws cov yam ntxwv sib txawv. Txhawm rau kom ua tau zoo ua si qhov siab tshaj plaws ntawm nws cov smelting, ua ke nrog kev tiv thaiv zoo ntawm kev siv lub sijhawm txwv ntawm qhov nruab nrab zaus rauv.
