Muchigadziro chekugadzirisa, nokuti kuchinja kwekupikisa kuchaita kuti kuchinja kwekugadzirisa ikozvino, iyo yekugadzira ikozvino inoda kugadziriswa munguva. Parizvino, nzira dzinowanzoshandiswa dzinosanganisira dynamic resistance method uye inogara iripo yekudzora nzira, nezvimwewo, ine chinangwa chekuchengeta welding ikozvino nguva dzose kuburikidza nekudzora matanho. Nemhaka yekuti kupikisa kwemasimba kwakaoma kuyera, kushanda kwekutonga kwakaoma kuita.
Naizvozvo, Xiaobian inotora inogara iripo yekudzora nzira yekukurukura, uye kutanga inoongorora zvikonzero zvinotungamira kune yakaderera welding ikozvino kutonga chaiko. Ikozvino kutonga kweyepakati frequency nzvimbo welding muchina, uchishandisa mutemo we thyristor conduction Angle kudzora welding ikozvino, China inoshandisa 50Hz alternating current, iyo nguva ndeye 20ms, kutenderera kwega kwega kune maviri hafu mafungu, imwe neimwe hafu wave iri 10ms, iyo ndiko, mutemo we thyristor conduction Angle inogona kungogadziriswa yega 10ms. Panyaya yekutonga kwedhijitari, nguva yekurova ndeye 10ms.
Iyi 10ms ndiro dambudziko: nguva yekurova yakarebesa. Sezvo kupikisa kwechinhu chichaiswa welded kuchichinja nekuwedzera kwekushisa, 10ms nguva yakakwana kuti ibudise huwandu hwakawanda hwekuchinja. Iyo conduction Angle yakaverengerwa panguva yekutanga ye10ms haichakodzeri kuhurumende mushure mekuchinja kwekupokana, saka iyo welding ikozvino ichaburitsa kukanganisa kukuru. Mushure mekunge iyo yakavharwa-loop control yagamuchirwa, iyo conduction Angle yekurova inotevera inogona kugadziridzwa zvinoenderana neiyo welding ikozvino inodzoserwa nemhinduro, asi dambudziko rimwechete richaramba richiitika mukurova kunotevera, uye kubuda ikozvino kwemutongi kunogara nguva dzose. kutsauka zvakanyanya kubva pakukosha kwakapihwa.
Kubva pane ongororo iri pamusoro, zvinogona kuoneka kuti yakarebesa kurova nguva ndicho chikonzero chikuru chinotungamira kune hombe welding ikozvino kukanganisa. Muchigadziro chekugadzira, kana shanduko yekudzivirira inogona kufanotaurwa mberi, uye zvinhu zvinofurira zvinotorwa pakuverenga pa-angle, imwe inonzwisisika pa-angle inogona kuwanikwa, kuitira kuti welding ikozvino iri pedyo neakapiwa. value. Zvichienderana neizvi, iyo feedforward control inowedzerwa pahwaro hweyakajairwa kutonga, uye iyo feedforward control algorithm inonyanya kufanotaura shanduko iripo inokonzerwa nekuramba shanduko. Saka chinangwa chechokwadi chekudzora welding ikozvino chinoitika.
