Inkqubo yokusebenza ye metal melting furnace.

A. Ukulungiselela ukusebenza

1. Khangela ukuba i-voltage yomgca ngamnye ongenayo iqhelekileyo.

2. Jonga ukuba uxinzelelo lwamanzi ngalunye kunye nendlela nganye yamanzi yesiqhelo.

3. Khangela ukuba izibane zesalathisi ezihambelanayo zebhodi yokulawula ephambili kunye ne-inverter pulse ziqhelekileyo.

Zonke ezi zinto zingasentla zingaqalisa ukunikezelwa kwamandla okufudumala phantsi kweemeko eziqhelekileyo.

B. Kungakhathaliseki ukuba luhlobo luni lwesiphaluka solawulo olusetyenziselwa ukusebenza kombane, xa uqala, kufuneka uqale uvule amandla okulawula, emva koko uvule amandla amakhulu, kwaye ekugqibeleni uqale isithando somlilo esinyibilikayo; xa imisiwe, ichasene nje, okokuqala misa isithando somlilo esinyibilikisayo, uze unqumle amandla amakhulu, kwaye ekugqibeleni unqunyulwe Vula amandla okulawula.

1. Qala ukusebenza.

Vala i-DZ encinci yokutshintsha umoya ukulungiselela ukuqalisa i-frequency intermediate.

Vala i-control power switch SA, isalathisi samandla i-HL1 sivuliwe, kwaye unikezelo lwamandla olawulo luvuselelwe.

Cinezela iqhosha eliphambili lokuvala isekethe i-SB1, isekethe ephambili inamandla, kwaye isandi sokuvala i-circuit breaker sinokuvakala.

Cinezela i-IF yokuqalisa/ukusetha ngokutsha iqhosha SB3, kwaye isalathisi esisebenzayo HL2 siya kuvula.

Kancinci uhlengahlengiso uhlengahlengiso lwamandla i-potentiometer PR kwaye ubeke ingqalelo kwimitha yokuphindaphinda. Ukuba kukho isalathiso kwaye unokuva umnxeba we-mid-frequency, oko kuthetha ukuba ukuqaliswa kuphumelele. Emva kokuba ukuqaliswa kuphumelele, vula i-potentiometer PR ukuya ekupheleni kanye, kwaye ngelo xesha, ukukhanya “ukuqala” kwibhodi yokulawula ephambili Vala, ukukhanya “kweRingi yoxinzelelo” kuvuliwe. Ukuba ukuqaliswa akuphumelelanga, kufuneka kuqalwe ngokutsha.

2. Misa utyando.

Jika i-potentiometer yohlengahlengiso lwamandla i-PR ikhawuntanga ukuya ekupheleni, kwaye zonke izixhobo ezibonisayo ziyi-zero.

Cinezela i-IF yokuqalisa / ukuseta kwakhona iqhosha SB3, isalathisi esisebenzayo HL2 siya kuphuma, kwaye i-IF iyakuyeka.

Cinezela iqhosha lesekethe eliphambili le-SB2, isekethe ephambili ivaliwe.

Vala i-control power switch SA, isalathisi samandla HL1 siya kuphuma, kwaye ukunikezelwa kwamandla okulawula kuya kunqunyulwa.

Vala umoya omncinci ukuze uvule i-DZ ngaphambi kokuba uphume emsebenzini.

3. Eminye imiyalelo

Xa kukho ukungasebenzi kakuhle, iphaneli yokulawula inokugcina imemori, kwaye unikezelo lwamandla lunokuqaliswa kwakhona emva kokuba ukungasebenzi kakuhle kupheliswe kwaye iqhosha eliphakathi lokuqala / lokusetha kwakhona iqhosha le-SB3 licinezelwe.

Kwimeko yesiphoso okanye unxunguphalo, kufuneka uqale ucofe iqhosha elithi IF qalisa/seta ngokutsha i-SB3, kwaye emva koko ucinezele inkqubo yonikezelo lwamandla yokumisa ukumisa unikezelo lwamandla, kwaye uqalise kwakhona unikezelo lwamandla emva kokusombulula ingxaki.

Ixesha lokumisa lompompo wamanzi kufuneka libekwe ngokuhambelana nokushisa kwamanzi kwi-coil induction of the melting furnace. Ngokuqhelekileyo, impompo yamanzi kufuneka imiswe malunga nemizuzu engama-30 emva kokumiswa kombane.
