Ungazikhetha kanjani izinto zokuxhumana zokushisela imvamisa ephezulu?

 Kunezinhlobo ezimbili eziyinhloko zokushisela imvamisa ephezulu, i-welding yokuxhumana kanye ne-induction welding. Ukushisela induction kuyindlela yokushisela engathintani usebenzisa amakhoyili. Ukushisela oxhumana nakho kusetshenziswa kwezinto zokuhambisa ukuhola ngqo imvamisa ephezulu manje endaweni yokushisela yamapayipi wensimbi, bese ushisela izinto ngemuva kokushisa.

Isicelo imvelo ephezulu imvamisa Welding izinto

Imvelo yokusebenza yekhanda lokushisela lokuthinta imvamisa ephezulu libukhali kakhulu, ikakhulukazi ngokulandelayo:

1) amanzi, i-emulsion, ukushisa okuphezulu, ukushisa, intuthu, igesi elonakalisayo noma uketshezi kungabonakala ngamehlo nqunu ezindaweni eziningi;

2) Ukuthwala imvamisa ye-AC yamanje kanye namandla kagesi, imvamisa yamanje ejwayelekile ingama-200 kHz-800 kHz, futhi okwamanje kuyahlukahluka kusuka kumakhulu amaningana ama-amperes kuya ezinkulungwaneni eziningana zama-amperes ngokwamandla emishini;

3) Ekukhiqizeni, oxhumana nabo bemishini basebenza ngaphansi kwengcindezi ethile, imvamisa kusuka ku-2 kuye ku-4 bar;

4) Okokusebenza kuhamba ngokuqhubekayo emgqeni, futhi oxhumana naye uhlala ethwala ukungqubuzana okushelelayo kwento eshiselwe ngezansi ngaphansi kwengcindezi;

5) Ngoba imvelo lapho otholakala khona ingcolile khona, futhi ne-oxide eyenziwe ngenqubo yokushiswa okuphezulu kokushisa koxhumana naye ishiswa ngokungathi sína, ukungcola kwe-oxide kuzokhunyiswa bese i-arc idonswa ngaphansi kwesenzo samanje esiphezulu;

6) Lapho into eshiselwe ngezansi ingalingani, ukumelana koxhumana naye kokuxhumana kuzoshintsha kakhulu, bese kuvela izinhlansi zikagesi zamazinga ahlukahlukene koxhumana naye;

Ngaphezu kwalezi zimo ezingenhla zemvelo, indawo yokusebenza yokuxhuma othintana nabo izobekelwa inselelo enkulu ngenxa yamandla acindezelayo oxhumana nabo abasebenza opharetha bezinsimu, ukuqina kwezinto ezisetshenzisiwe, ubulukhuni bezinto ezisetshenzisiwe, amandla okulwa komhlaba kanye njalonjalo.

Izidingo zobuntu bezinto zokuxhumana zokushisela imvamisa ephezulu

   Ngenxa yezidingo zokusebenza koxhumana nabo be-welding othintana nabo kanye nemikhawulo yokusebenza kwemvelo yekhanda le-welding, izidingo ezikhethekile zesici zibekwa phambili ezintweni zekhanda le-welding contact. Njengekhanda le-welding lokuxhumana, izinto zalo kufanele zisebenze ngokuhambisana nokusebenza okusebenzayo kulezi zici ezilandelayo:

1) ukuqhuba, ngoba oxhumana naye uphethe izidingo ezinkulu zokuphatha zamanje, izinto zokuxhumana kufanele zibe nokuqhuba okuphezulu ukunciphisa ukumelana koxhumana nabo, ukukhishwa okuphansi okuphansi nokukhishwa okukhanyayo ukunciphisa isikhathi samanje se-arc nesikhathi se-arc, ngakho-ke izinto kufanele zibe nokuhamba okuphezulu;

2) Ikhono lokuqhuba ukushisa, ngoba oxhumana naye uphethe i-current enkulu, izinga lokushisa lalo liphakeme, ngakho-ke kufanele libe namandla athile wokuqothula ukushisa kanye namandla aphezulu wokuqhuba ukushisa ukuze ukushisa okwenziwe i-arc noma i-Joule umthombo wokushisa ungadluliselwa kusisekelo soxhumana naye ngokushesha ngangokunokwenzeka;

3) Amandla, ngoba oxhumana naye usebenza ngaphansi kwengcindezi ethile, kuyadingeka futhi ukuthi ubheke ukuqina kwento;

4) Gqoka ukumelana, ngoba oxhumana naye uhlala ehlikihla ebusweni bento eshiselwe ngesikhathi somsebenzi, izinto zokuxhumana zidinga ukumelana nokuguga okukhulu;

I-5) Ukuqina nakho kungenye yezimpawu okufanele zicatshangelwe. Ngaphansi kwengcindezi ethile yokuxhumana, ubulukhuni obuncane bungakhuphula indawo yokuxhumana, banciphise ukumelana koxhumana nabo, futhi banciphise ukuthambekela kokufudumeza oxhumana nabo nokushisela okungaguquguquki ngesikhathi sokuxhumana okungaguquki. Ubulukhuni obuphakeme bunganciphisa indawo yokushisela futhi buthuthukise ukumelana nokugqokwa kwemishini;

Ungazikhetha kanjani izinto zokuxhumana?

Ukukhethwa kwezinto zokuxhumana ikakhulu kuya ngezindleko, izidingo zomkhiqizo womkhiqizo, izidingo zosayizi wendawo yokushisela umkhiqizo kanye nezici zomkhiqizo.

1. ithusi elijwayelekile elingenawo umoya-mpilo noma ithusi elingena-oksijini elingenawo umoya liyamukelwa lapho kukhethwa ezintweni ezijwayelekile, futhi ukuhanjiswa kwethusi kufinyelela kuma-99%;

2. Khetha ingxubevange yethusi, efana ne-tungsten-copper alloy, khetha i-chromium copper, i-tungsten carbide alloy copper, njll .;

3. Amanye ama-alloys, njenge-titanium alloys; Ukukhetha izinto ze-alloy, okuqukethwe okukhethekile kwe-copper kanye ne-alloy okuqukethwe kudinga ukunqunywa ngokuya ngohlelo lokusebenza lwangempela lwensimu, kubhekwe ukuqhutshwa, ukugqoka ukumelana, izidingo zomhlaba zomkhiqizo, njll.

Okuqukethwe yi-athikili kuvela kwezinye izindawoKunezinhlobo ezimbili eziyinhloko zokushisela imvamisa ephezulu kakhulu, i-welding yokuxhumana kanye ne-induction welding. Ukushisela induction kuyindlela yokushisela engathintani usebenzisa amakhoyili. Ukushisela oxhumana nakho kusetshenziswa kwezinto zokuhambisa ukuhola ngqo imvamisa ephezulu manje endaweni yokushisela yamapayipi wensimbi, bese ushisela izinto ngemuva kokushisa.

5.Application imvelo ephezulu imvamisa Welding izinto

Indawo yokusebenza ye-high-frequency contact welding head inzima kakhulu, ikakhulukazi ngokulandelayo:

7. amanzi, i-emulsion, ukushisa okuphezulu, ukushisa, intuthu, igesi elonakalisayo noma uketshezi kungabonakala ngamehlo nqunu ezindaweni eziningi;

8. Ukuthwala imvamisa ye-AC yamanje kanye namandla kagesi, imvamisa yamanje ejwayelekile ingama-200 kHz-800 kHz, futhi okwamanje kuyahlukahluka kusuka kumakhulu amaningana ama-ampere kuye ezinkulungwaneni eziningana zama-amperes ngokwamandla emishini;

9. Ekukhiqizeni, oxhumana nabo bemishini basebenza ngaphansi kwengcindezi ethile, imvamisa kusuka ku-2 kuye ku-4 bar;

Imishini isebenza ngokuqhubekayo kulayini, futhi oxhumana naye uhlala ethwala ukungqubuzana okushelelayo kwento eshiselwe ngezansi ngaphansi kwengcindezi;

11.Ngombana indawo lapho othintana naye atholakala khona ingcolile, futhi ne-oxide ekhiqizwe ngenqubo yokushiswa okuphezulu kokushisa koxhumana naye ishiswa ngokungathi sína, ukungcola kwe-oxide kuzokhelelwa bese i-arc idonswa ngaphansi kwesenzo samanje aphezulu;

12. Lapho into eyinsimbi engezansi ingalingani, ukumelana koxhumana naye koxhumana naye kuzoshintsha kakhulu, bese kuvela izinhlansi zikagesi zamazinga ahlukahlukene koxhumana naye;

Ngaphezu kwalezi zimo ezingenhla zemvelo, indawo yokusebenza yokuxhuma othintana nabo izobekelwa inselelo enkulu ngenxa yamandla acindezelayo oxhumana nabo abasebenza opharetha bezinsimu, ukuqina kwezinto ezisetshenzisiwe, ubulukhuni bezinto ezisetshenzisiwe, amandla okulwa komhlaba kanye njalonjalo.
