Medium-frequency direct current (MFDC) spot welding machines anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekunyatso batanidza simbi. Kuti uve nechokwadi chekugara kwenguva refu uye kushanda kwemakina aya, inoshanda yekutonhodza system yakakosha. Ichi chinyorwa chinopa tarisiro yekurongeka kwemasisitimu ekutonhodza eMFDC spot welding michina.
I. Mhepo Inotonhorera System
Iyo air cooling system ndiyo inonyanya kushandiswa mhando yeMFDC spot welding machines. Inosanganisira kushandiswa kwemafeni kubvisa kupisa kunogadzirwa panguva yekugadzira welding. The classification mukati meiyi system inogona kukamurwazve muzvikamu zviviri:
- Kutonhodza Mhepo:
- Munzira iyi, mafeni ane simba anoshandiswa kufuridzira mweya unotonhorera pamusoro pezvinhu zvemuchina, kusanganisira ma transformer, diode, uye tambo.
- Iyi sisitimu inodhura-inoshanda uye iri nyore kuchengetedza.
- Natural Air Cooling:
- Kutonhodza kwemhepo yakasikwa kunoenderana nekugadzirwa kwemuchina kuti ubvumire kutenderera kwemhepo yakatenderedza kumativi ayo.
- Kunyange ichishanda nesimba, inogona kunge isingakodzeri michina ine kupisa kwakanyanya.
II. Mvura Inotonhorera System
Mvura yekutonhodza masisitimu anoshandiswa kana kupisa kunogadzirwa neMFDC spot welding machine kwakakwira zvakanyanya. Iyi sisitimu inogona kuiswa mumhando dzinotevera:
- Yakavharwa-Loop Mvura Kutonhodza:
- Nenzira iyi, chirongwa chakavharwa chinotenderera mvura kuburikidza nemhepo inopisa, iyo inobvisa kupisa zvakanaka.
- Yakavharwa-loop masisitimu anoshanda zvakanyanya mukuchengetedza kudziya kunoenderana.
- Open-Loop Mvura Kutonhodza:
- Vhura-loop masisitimu anoshandisa kuenderera kuyerera kwemvura kubvisa kupisa kubva pamushini.
- Kunyange zvazvo ichishanda, inogona kusanyanya kushanda pane yakavharwa-loop masisitimu.
III. Hybrid Kutonhora System
Mimwe MFDC spot welding machines inosanganisa ese ari maviri emhepo nemvura ekutonhodza masisitimu kuti agone kuita. Iyi hybrid system inobvumira kudzora tembiricha zvirinani, kunyanya mumakina ane mareti ekupisa anosiyana.
IV. Oiri Kutonhora System
Oiri yekutonhodza masisitimu haanyanye kuwanda asi inopa yakanakisa kupisa kupisa kugona. Vanokamurwa kuva:
- Kunyudza Kutonhodza:
- Mukunyudza kutonhora, zvikamu zvemuchina zvinonyudzwa mumafuta edielectric.
- Iyi nzira inoshanda mukupisa kupisa uye inopa kuwedzera kwekudzivirira.
- Direct Oiri Kutonhodza:
- Kutonhorera kwakananga kwemafuta kunosanganisira kutenderera kwemafuta kuburikidza nemachaneli kana mabhachi akatenderedza zvinhu zvakakosha.
- Iyi nzira yakakodzera michina ine nyaya dzekudziya dzemuno.
Sarudzo yekutonhodza sisitimu yeMFDC spot welding muchina zvinoenderana nezvinhu zvakaita sedhizaini yemuchina, kugadzira kupisa, uye kutariswa kwemitengo. Kunzwisisa kupatsanurwa kweaya masisitimu ekutonhodza kwakakosha pakuve nechokwadi chekushanda kwakakwana uye hupenyu hurefu hweaya akakosha maturusi maturusi. Kusarudza iyo chaiyo yekutonhodza sisitimu inogona kuvandudza welding mhando, kuderedza mari yekugadzirisa, uye kuwedzera hupenyu hwemuchina.
