Mawonekedwe Amagetsi a Welding Circuit mu Medium Frequency Inverter Spot Welding Machine

The kuwotcherera dera ndi chigawo chofunika sing'anga pafupipafupi inverter malo kuwotcherera makina, udindo popereka zofunika mphamvu magetsi ndondomeko kuwotcherera. Kumvetsetsa mawonekedwe amagetsi a wowotcherera dera ndikofunikira kuti muwonetsetse kuti ntchito zowotcherera zikuyenda bwino komanso zodalirika. M'nkhaniyi, tiona makhalidwe magetsi a kuwotcherera dera sing'anga pafupipafupi inverter malo kuwotcherera makina.

1. Kupereka Mphamvu: Mphamvu yamagetsi ndiye gwero lalikulu lamphamvu zamagetsi pagawo lowotcherera. Mu makina owotcherera apakati pafupipafupi, magetsi amakhala ndi chowongolera komanso cholumikizira cha DC. Chowotchera chimasintha mphamvu ya AC yomwe ikubwera kukhala mphamvu ya DC, pomwe cholumikizira cholumikizira cha DC chimatulutsa mphamvu yamagetsi, ndikupatsa mphamvu ya DC yokhazikika pagawo lowotcherera.
2. Inverter: Inverter ndi gawo lofunikira lomwe limasintha mphamvu ya DC kuchokera pamagetsi kupita kumagetsi apamwamba kwambiri a AC. Zimapangidwa ndi zida zamagetsi zamagetsi, monga insulated gate bipolar transistors (IGBTs), zomwe zimasinthira magetsi a DC pafupipafupi kwambiri (nthawi zambiri mumitundu ingapo ya kilohertz). Kusintha kwa inverter kumayang'anira kuwotcherera pakali pano ndikulola kuwongolera bwino njira yowotcherera.
3. Transformer: Transformer mu welding circuit imayang'anira kukwera kapena kutsika voteji ndikusamutsa mphamvu yamagetsi ku ma elekitirodi owotcherera. Amakhala pulayimale ndi sekondale windings, ndi mapiringidzo oyambirira olumikizidwa kwa inverter ndi yachiwiri makhota olumikizidwa kwa maelekitirodi kuwotcherera. Chiŵerengero cha matembenuzidwe a thiransifoma chimatsimikizira kusintha kwa magetsi ndipo chimagwira ntchito yofunika kwambiri kuti akwaniritse zomwe akufunidwa pakalipano komanso kutulutsa mphamvu.
4. Ma Electrodes Owotcherera: Ma elekitirodi owotcherera ndi malo olumikizirana pomwe magetsi amadutsa pa chogwirira ntchito, ndikupanga weld. Nthawi zambiri amapangidwa ndi zinthu zopangira, monga mkuwa, ndipo amapangidwa kuti azitha kupirira kutentha komanso kutentha komwe kumapangidwa panthawi yowotcherera. Makhalidwe amagetsi a ma elekitirodi owotcherera, kuphatikiza kukana kwawo ndi malo olumikizana nawo, amakhudza magwiridwe antchito onse amagetsi ozungulira.
5. Dongosolo Loyang'anira: Dongosolo lowongolera mu sing'anga pafupipafupi inverter malo kuwotcherera makina oyang'anira ndikuwongolera magawo amagetsi a dera lowotcherera. Zimaphatikizapo masensa, monga masensa apano ndi ma voltage, omwe amapereka ndemanga ku gawo lowongolera. Chigawo chowongolera chimayendetsa chidziwitsochi ndikusintha ma frequency osinthika a inverter, kuzungulira kwa ntchito, ndi magawo ena kuti asunge zowotcherera zokhazikika.

Makhalidwe amagetsi a makina owotcherera pamakina apakati pafupipafupi inverter spot kuwotcherera ndi ofunikira kuti akwaniritse ntchito zowotcherera bwino komanso zogwira mtima. Kumvetsetsa udindo wa magetsi, inverter, thiransifoma, ma elekitirodi owotcherera, ndi makina owongolera amathandizira ogwiritsa ntchito kukhathamiritsa njira yowotcherera ndikuwonetsetsa kuti magetsi akugwira ntchito. Poganizira ndikuwongolera mawonekedwe amagetsi awa, ogwiritsa ntchito amatha kukwaniritsa ma welds apamwamba kwambiri ndikuwongolera bwino magawo awotcherera.
