Isikhokelo sokugqibela sokukhetha indawo egqibeleleyo yecandelo le-candelo lendawo yakho ye-welding

1. Intshayelelo

Ukukhetha indawo efanelekileyo yecandelo lecandelo le-welding libaluleke ngakumbi kunokuba unokucinga. Ichaphazela ngokuthe ngqo intsebenzo yamatshini wakho we-welding kwaye iqinisekisa ukhuseleko ngexesha lokusebenza. Ezona zinto zimbini ziphambili zokugcina engqondweni xa usenza ukhetho lwakho sisixa sekhebula langoku elinokuphatha kwaye i-voltage ihhlise ubude bayo. Ukutyeshela ezi zinto kunokukhokelela ekusebenzeni kakhulu, ukusebenza kakubi, okanye ukonakala kwezixhobo ezinzulu.

Makhe sikhuphe into ekufuneka uyazi ngendlela elula, enenyathelo ngenyathelo.

2. Izinto eziphambili ekufuneka ziqwalaselwe

Xa ukhetha intambo ye-welding, kukho izinto ezimbini ezibalulekileyo:

1. Umthamo wangoku:
   • Oku kubhekisa ukuba ingakanani intambo yentambo ngokukhuselekileyo ngokukhuselekileyo. Ubungakanani bentambo (indawo enqamlezileyo) ichaza amandla ayo.
   • Kwiintambo zimfutshane kwiimitha ezingama-20, unokuhlala ugxile kwi-Ampukucuku- jikelele, kuba ukuhla kwevolthi akuyi kuba njalo.
   • Iintambo ezinde, nangona kunjalo, zifuna ukhathalelo ngononophelo kuba ukuxhathisa kwentambo kunokukhokelela ekwehlayo kwivolthi, echaphazela ukusebenza kwe-SOD ye-SOD.
2. I-voltage yehlile:
   • I-voltage yehla ibabalulekile xa ubude bentambo bungaphezulu kweemitha ezingama-20. Ukuba intambo icekeceke kakhulu ukuba ithwale ngoku, ilahleko ye-voltage inyuka, ukunciphisa amandla ahanjiswe kumatshini we-welding.
   • Njengomthetho wesithupha, ukuhla kwevolthi akufuneki idlule kwi-4V. Ngaphandle kwe-50 yeemitha, kuya kufuneka uhlengahlengise ukubalwa kwaye ukhetha intambo yentambo yokuthintela intambo yokufezekisa iimfuno.

3. Ukubala icandelo le-ross

Makhe sijonge umzekelo ukubona ukuba isebenza njani le nto:

• Masithi i-welding yakho yangokuI-300A, kunye nenqanaba lomthwaloI-60%. Okwangoku ibala njenge:
  $I-300A\; \times \; 60\%\; =\; 234A300A\; \backslash \; Times\; 60\; \backslash \%\; =\; 234A$

  I-300A × 60% = 234A

• Ukuba usebenza ngoxinaniso lwangoku lweI-7a / mm², Uyakufuna intambo kunye nendawo enqamlezileyo yecandelo:
  $234A\; ÷\; 7a\; /\; mm2\; =\; 33.4mm2234a\; \backslash \; ving\; 7a\; /\; mm²\; =\; 33mm²\; =\; 33mm²\; =\; 33mm²\; =\; 33mm²$

  234a ÷ 7a / mm2 = 33.4mm2

• Ngokusekwe kwesi siphumo, owona mdlalo ubalaseleyo uya kubaYhh-35 intambo yerabha yerabha, enendawo enqamlezayo ye-35mm².

Le cable iya kuphatha okwangoku ngaphandle kokukhathaza kwaye isebenze ngokufanelekileyo ngaphezulu kweemitha ezingama-20.

I-4. Ubume be-YHH ye-yelda

Yintoni intambo ye-YHH?I-YHh Welding yeentambo zenzelwe uqhagamshelo oluthile kwicala lenqanaba lesibini kuomatshini bokukhula. Ezi ntambo zinzima, ziyaguquka, kwaye zilungele kakuhle iimeko ezinzima ze-welsh.

• Ukuhambelana kwe-voltage: Banokujongana ne-ac voltages voltages ukuya kuthi gaI-200Vkunye ne-DC Peak voltages ukuyaI-400V.
• Iqondo lokusebenza: Elona qondo lobushushu liphezuluI-60 ° C, ukuqinisekisa ukusebenza ngokuthembekileyo kude kusetyenziswe uqhubeke.

Kutheni le yhh?Ubume obukhethekileyo beegesi ze-YHH bubenza babe bhetyebhetye, ukucamngca lula, kunye nokunganyangeki ukunxiba kunye nokukrazula. Ezi ndawo zibalulekile kwizicelo ze-welding apho kuya kubakho khona ukuhamba rhoqo.

5. Itafile yeCable

Apha ngezantsi kukho itafile ye-YHh yeentambo. Ibalaselisa iiparamitha eziphambili, kubandakanya ubungakanani be-cable, indawo efanayo yendawo enqamlezayo, kunye nomqhubi wokuqhuba.

Ithini le theyibhile?

• I-OWG (i-wire yaseMelika): Amancinci amancinci athetha iingcingo ezikhulu.
• Ubungakanani obulinganayo: Ibonisa indawo enqamlezileyo kwi-MM².
• Isifundo somqhubi: Ukuxhathisa okuphantsi kuthetha ukuba i-voltage encinci yehla.

6. Izikhokelo eziSebenzayo zokhetho

Nalu uluhlu lokutshekisha ngokukhawuleza ukukunceda ukhethe intambo efanelekileyo:

1. Ukulinganisa ubude bentambo yakho ye-welding.
2. Chonga owona matshini uphelileyo womatshini we-welding uya kuyisebenzisa.
3. Qwalasela umthwalo wexesha lexesha (ukuba umatshini uhlala kangakanani).
4. Jonga i-voltage yehlelo lemingxunya emide (ngaphezulu kwe-20m okanye i-50m).
5. Sebenzisa itheyibhile yokucacisa ukufumana owona mdlalo ubalaseleyo usekwe kwixesha elikhoyo kunye nobungakanani.

Ukuba uthandabuza, ihlala ikhuselekile ukuhamba nentambo enkulu kancinane. Intambo emdaka inokubiza ngaphezulu, kodwa iya kubonelela ngokusebenza ngcono kwaye ihlale ixesha elide.

7. Ukuqukumbela

Ukukhetha intambo ye-welding ye-welding kuyo yonke into malunga nokulinganisa umthamo kunye nevolimu ngelixa ugcina ukhuseleko kunye nokusebenza kakuhle engqondweni. Nokuba usebenzisa intambo ye-10mmt kwimisebenzi elula okanye intambo ye-95mm² yezicelo ezinzima, qinisekisa ukutshatisa intambo kwiimfuno zakho ezithile. Kwaye ungalibali ukukhangela iitafile zokuchaza ukuze ufumane isikhokelo esichanekileyo.
