Cutting specifications:
Yakasiyana-siyana yeplasma arc yekucheka maparameter inobata zvakananga kugadzikana, kutema mhando uye mhedzisiro yekucheka maitiro. The mainplasma arc yekucheka muchina cutting specifications dzinotsanangurwa muchidimbu sezvinotevera:
1.No-load voltage uye arc column voltage Plasma yekucheka magetsi inofanira kuva nepamusoro yakakwana isina-load voltage kuti itungamirire arc nyore nyore uye iite kuti plasma arc inopisa zvakasimba. Iyo isina-mutoro voltage inowanzoitika 120-600V, nepo arc column voltage kazhinji iri hafu yeasina-mutoro voltage. Kuwedzera iyo arc column voltage inogona kuwedzera zvakanyanya simba re plasma arc, nekudaro ichiwedzera kumhanya kwekucheka uye kucheka hukuru hukuru hwesimbi plate. Iyo arc column voltage inowanzoitwa kuburikidza nekugadzirisa gasi kuyerera uye kuwedzera mukati shrinkage ye electrode, asi arc column voltage haigoni kudarika 65% ye-no-load voltage, kana zvisina kudaro plasma arc ichave isina kugadzikana.
2.Kucheka ikozvino Kuwedzera kucheka ikozvino kunogonawo kuwedzera simba re plasma arc, asi inogumira nepamusoro inobvumirwa ikozvino, kana zvisina kudaro ichaita kuti plasma arc column iwedzere, hupamhi hwekucheka kwekucheka kunowedzera, uye hupenyu hwe electrode hunoderera.
3.Kuyerera kwegasi Kuwedzera kuyerera kwegasi hakugone kungowedzera arc column voltage, asiwo kunowedzera kudzvanywa kwearc column uye kuita kuti plasma arc simba riwedzere kusimba uye simba rejeti rive rakasimba, kuitira kuti kucheka kukurumidza uye kunaka kunogona kuvandudzwa. Zvisinei, iyo gasi inoyerera yakakura zvikuru, asi ichaita kuti arc column ipfupike, kurasikirwa kwekupisa kunowedzera, uye kukwanisa kwekucheka kunopera kusvikira nzira yekucheka isingakwanisi kuitwa kazhinji.
4.Kuwanda kwe electrode shrinkage Iyo inonzi shrinkage yemukati inoreva kureba kubva kune electrode kusvika kumagumo emuromo wekucheka, uye chinhambwe chakakodzera chinogona kuita kuti arc inyatso kudzvanywa mumuromo wekucheka, uye kuwana plasma arc ine simba rakanyanya. uye kupisa kwakanyanya kwekucheka kunobudirira. Yakanyanya kukura kana diki chinhambwe chinokonzeresa kupisa kwakanyanya kwe electrode, kupisa kweanocheka uye kuderera kwekucheka kugona. Huwandu hwemukati shrinkage kazhinji 8-11mm.
5.Cheka mhuno kureba Kureba kwenozzle kunoreva chinhambwe kubva kumagumo emuromo wakachekwa kusvika pamusoro pechekwa chekushanda. Nhambwe yacho inowanzoita 4 kusvika 10 mm. Izvo zvakafanana nekuderera kwemukati kwe electrode, kureba kunofanira kunge kwakakodzera kupa kutamba kwakazara kune kucheka kwekucheka kwe plasma arc, kana zvisina kudaro kucheka kwekucheka uye kutema kwehutano kuchaderedzwa kana muromo wekucheka uchapisa.
6.Kucheka kumhanya Izvo zviri pamusoro apa zvinokanganisa kukanganisa kweiyo plasma arc, ndiko kuti, tembiricha uye simba density yeplasma arc, uye tembiricha yepamusoro uye simba rakakura re plasma arc rinotarisa kumhanya kwekucheka, saka izvo zviri pamusoro zvine hukama. kune kukurumidza kucheka. Pasi pechigadziro chekuvimbisa hutano hwekucheka, kasi yekucheka inofanira kuwedzerwa zvakanyanya sezvinobvira. Izvi hazvisi kungowedzera zvibereko, asi zvakare zvinoderedza kuwanda kwekushandurwa kwechikamu chakachekwa uye nzvimbo yakakanganiswa inopisa yenzvimbo yakachekwa. Kana kukurumidza kucheka kusina kukodzera, mhedzisiro inodzoserwa, uye iyo inonamira slag ichawedzera uye kucheka kunaka kunoderera.
Chengetedzo Chengetedzo:
1.Chikamu chezasi chekucheka kweplasma chinofanira kugadzikwa nedhishi, uye chikamu chekucheka chinofanira kuchekwa pasi pemvura panguva yekucheka kudzivirira kuchetura kwemuviri wemunhu nekugadzira flue gasi.
2.Dzivisa kuona kwakananga kunoonekwa kweplasma arc panguva yeplasma arc yekucheka maitiro, uye pfeka ehunyanzvi magirazi ekudzivirira uye kumeso masks kudzivirira kupisa kumaziso uye.ngowani yomotone arc.
3.Huwandu hwemagasi ane muchetura huchagadzirwa panguva yeplasma arc yekucheka maitiro, iyo inoda kufefetedza uye kupfeka yakawanda-layer sefa guruva.mask.
4.Mune plasma arc cutting process, zvakakosha kupfeka tauro, magirovhosi, tsoka sheaths uye mamwe mabasa ekudzivirira midziyo kudzivirira kutsva kweganda ne splashing mars.5. Mune plasma arc yekucheka maitiro, iyo yakakwira frequency uye electromagnetic radiation inogadzirwa neakakwira-frequency oscillator inokonzeresa kukuvadza kumuviri, uye vamwe varapi venguva refu vanotove nezviratidzo zvekushaya mbereko, kunyangwe nharaunda yekurapa neindasitiri ichiri kusanzwisisa, asi vachiri kuda kuita basa rakanaka rekudzivirira.
