UHlelo lweeNkqubo zokuPholisa kwiMishini ye-Welding ye-Medium-Frequency Direct yangoku

Oomatshini bokuwelda bamabala aphakathi (MFDC) basetyenziswa kakhulu kumashishini ahlukeneyo ngokuchaneka kunye nokusebenza kakuhle ekudibaniseni iintsimbi. Ukuqinisekisa ixesha elide kunye nokusebenza kakuhle kwaba matshini, inkqubo yokupholisa esebenzayo ibalulekile. Eli nqaku liza kubonelela ngolwahlulo lweenkqubo zokupholisa zeMFDC koomatshini bokuwelda indawo.

I. Inkqubo yokupholisa umoya

Inkqubo yokupholisa umoya lolona hlobo luxhaphakileyo olusetyenziselwa oomatshini bokuwelda bamabala beMFDC. Kubandakanya ukusetyenziswa kweefeni ukutshabalalisa ubushushu obuveliswe ngexesha lenkqubo ye-welding. Ulwahlulo kule nkqubo lunokwahlulwa lube ziindidi ezimbini:

1. Ukupholisa Umoya Ngenkani:
   • Kule ndlela, iifeni ezinamandla zisetyenziselwa ukuvuthela umoya opholileyo kwizinto zomatshini, eziquka ii-transformer, ii-diode kunye neentambo.
   • Le nkqubo ineendleko-zonga kwaye kulula ukuyigcina.
2. Ukupholisa uMoya weNdalo:
   • Ukupholisa komoya wendalo kuxhomekeke kuyilo lomatshini ukuvumela ukujikeleza komoya ojikeleze iinxalenye zawo.
   • Ngelixa inamandla ombane, isenokungalungeli oomatshini abavelisa ubushushu obuphezulu.

II. Inkqubo yokupholisa amanzi

Iinkqubo zokupholisa amanzi zisetyenziswa xa ubushushu obuveliswa ngoomatshini bokuwelda bendawo be-MFDC buphezulu kakhulu. Le nkqubo ingahlelwa ngokwezi ntlobo zilandelayo:

1. Ukupholisa kwaManzi okuvaliweyo:
   • Kule ndlela, inkqubo ye-loop evaliweyo ijikeleza amanzi nge-heat exchanger, ekhupha ukushisa ngokufanelekileyo.
   • Iinkqubo ezivaliweyo zisebenza ngakumbi ekugcineni amaqondo obushushu angaguqukiyo.
2. Ukupholisa kwaManzi okuVulekileyo:
   • Iinkqubo ezivulekileyo ze-loop zisebenzisa ukuhamba kwamanzi okuqhubekayo ukususa ubushushu kumatshini.
   • Ngelixa zisebenza, zinokusebenza kancinci kuneenkqubo ezivaliweyo.

III. Inkqubo yokupholisa yeHybrid

Abanye oomatshini bokuwelda bamabala be-MFDC badibanisa zombini iinkqubo zokupholisa umoya kunye namanzi ukwenza ngcono ukusebenza. Le nkqubo ye-hybrid ivumela ulawulo olungcono lobushushu, ngakumbi koomatshini abanemilinganiselo yokuvelisa ukushisa.

IV. Inkqubo yokupholisa i-oyile

Iinkqubo zokupholisa i-oyile azixhaphakanga kangako kodwa zibonelela ngezakhono ezibalaseleyo zokuphelisa ubushushu. Zahlulwe ngokwe:

1. Ukuntywiliselwa ukuPholisa:
   • Ekupholiseni kokuntywiliselwa, amacandelo omatshini afakwe kwioli ye-dielectric.
   • Le ndlela isebenzayo ekutshitshiseni ubushushu kwaye ibonelela nge-insulation eyongezelelweyo.
2. Ukupholisa i-Oli ngokuthe ngqo:
   • Ukupholisa ioli ngokuthe ngqo kubandakanya ukujikeleza kweoyile ngokusebenzisa imijelo okanye iibhatyi ezijikeleze amacandelo abalulekileyo.
   • Le ndlela ifanelekile koomatshini abanemiba yokufudumeza kwendawo.

Ukhetho lwenkqubo yokupholisa kumatshini we-MFDC wokuwelda kuxhomekeke kwizinto ezifana noyilo lomatshini, ukuveliswa kobushushu, kunye nokuqwalaselwa kweendleko. Ukuqonda ukuhlelwa kwezi nkqubo zokupholisa kubalulekile ekuqinisekiseni ukusebenza ngokugqibeleleyo kunye nobomi obude bezi zixhobo zoshishino zixabisekileyo. Ukukhetha inkqubo yokupholisa efanelekileyo kunokuphucula umgangatho we-welding, ukunciphisa iindleko zokulondoloza, kunye nokwandisa ubomi bomatshini.
