Ukusika kwe-plasma yensimbi

Ubuchwepheshe obusha bokucubungula izinto eziqinile kukuvumela ukuba uphathe ngokushesha futhi ngempumelelo cishe noma yisiphi isakhiwo. I-Metal ingasuswa kalula ngokusebenzisa amadivayisi abrasive kanye laser. Ngisho nezinhloko zendabuko ezinama- diamond discs ziqinisekisa ukusika okusezingeni eliphezulu kwamashidi amakhulu. Enye yezindlela eziphumelela kakhulu zokuxazulula izinkinga ezinjalo ukusika insimbi ye-plasma. Isithombe ngezansi sibonisa le nqubo.

Ulwazi olujwayelekile mayelana nobuchwepheshe

Le ndlela yenzelwe ukucubungula insimbi ngaphandle kokusebenzisa ama-saw blades. Njengamanye amasu okugcoba okutshisayo, le ndlela ihlanganisa ukudala ukusika kwesakhiwo ngendwangu yesigxobo endaweni yokusebenza. I-plasma ihlukaniswa ngokuqondile nemisebe yomoya oshisayo, umthombo wawo oyithuluzi elikhethekile. Njengomthetho, lo umshini onesibani se-plasma.

Ngokuvamile, le nqubo ifana ne-souder classic, kodwa kukhona umehluko omkhulu. Isibonelo, umoya oshaya umoya ugeleza ngenxa yalokho kubumba inqwaba ngobuningi obuncibilikisiwe. Ukulungele ngale ndlela, isisekelo siphenduka kakhulu, ngakho-ke ukusika kwe-plasma kuvumela opharetha ukuba anqume ngokunemba okuphezulu kungakhathaliseki ukuthi imingcele yomsebenzi.

Ukusetshenziswa kwe-plasma cutting

Izinsiza zokucubungula i-plasma zikuvumela ukuba wenze imisebenzi enezikhala zezinsimbi ezingezona ezensimbi nezensimbi. Futhi, kuye ngokuthi idivayisi, umsebenzisi angakwazi ukusika ama-alloys nama-billets aphikisayo ngokulingana okungaba ngu-40 mm. Lokhu buchwepheshe busetshenziswe ngempumelelo kumasifundisane obuciko. Ngokwengxenye, le ndawo yokusetshenziswa kwamathuluzi anjalo ingafaniswa nokufakelwa. Ochwepheshe benza imikhiqizo yokuhlobisa yokuqala yokuhlobisa amasango, izicingo kanye nefenisha. Ukwakhiwa kwezinto ezinomugqa wokusika we-curvilinear kwenza kube lula ukwenza ukusika kwe-plasma. Isithombe ngezansi sibonisa isibonelo sokucubungula okufakiwe.

Ngaphandle kwezikhombisi-ndlela zokudala, indlela isetshenziselwa izimboni nakumkhakha wokwakha. I-plasma ingakwazi ukusingatha noma iyiphi insimbi eqhuba amanje kagesi. Kwezinye izindawo, akuyona kakhulu ukusika kwezikhala ezibalulekile, kodwa ukucubungulwa kwamaphethelo. Ukusebenza okufanayo nakho kwenziwa ngabaqambi be-plasma.

Isimiso sesenzo se-plasmic

Le nqubo iqala ngokubunjwa kwe- arc kagesi phakathi komsebenzi wokusebenza kanye ne-electrode ku-cutter cutter . Ngezinye izikhathi ukushisa okwehlukile kwenzeka ngokuxhumana phakathi kombhobho we-apparatus kanye ne-electrode. Ukwakhiwa kokugeleza kwe-plasma kubonakala ngenxa yegesi enikezwe ikhanda lensiza. Ngaphezu kwalokho, ngaphansi kwengcindezi ephakeme, i-arc kagesi ikhiqizwa ngombuso wokushisa we-15,000 ° C. Kuye ngezici zezinto ezibonakalayo, lokhu noma lelo gesi eliphakathi lisetshenziswa. Isibonelo, ukusika ishidi lamaplasma usebenzisa i-hydrogen noma i-nitrogen kufanelekile kumamaki ombala. Ngakolunye uhlangothi, i-oksijini iyoba yindlela engcono kakhulu yokucubungula insimbi emnyama. Ngesikhathi sokusebenza, u-opharetha udinga ukulawula okugcwele kwe-jet esebenzayo. Ngokushesha ngemva kokusebenza kwe-arc kagesi, ukukhiqizwa kokugeleza kwe-plasma ku-inthanethi kuqala. Ukuphatha idivayisi, umsebenzisi ulungisa imingcele ye-flare eyakhiwe, ukuyiqondisa emgqeni wokusika emsebenzini.

Izinhlobo zemishini yokusika

Njengomthetho, abagawuli be-plasma bahlukaniswe ngamadivayisi we-transformer namadivayisi we-inverter uhlobo. Iqembu lokuqala limelelwa ngamamodeli oklanyelwe ukusika amashidi ensimbi 35-40 mm obukhulu. Ama-inverters abonakala ngobukhulu obuphansi futhi ngesikhathi esifanayo ukusebenza okuphakeme kuqhathaniswa nabaguquli. Noma kunjalo, izinga eliphakeme lokucubungula ngezindleko eziphansi kagesi linikezwa kuphela ezimweni lapho i-plasma igawulwa ngensimbi obunzima obungaphezu kwe-30 mm. Futhi, amadivaysi ahluke ngohlobo lwesistimu yokupholisa ibhulogi - ikakhulukazi, kunamamodeli akhiqiza amanzi. Esikhathini sokuqala, i-cooling medium iyinjethi yamanzi, kanti negesi lesibili. Ezingxenyeni ezinkulu, amanzi asetshenziswa njalo, okwenza kube nokwandisa ukunemba kwemisebenzi. Ukuhlinzeka ngemithombo ephakeme yokusebenza, ezobuchwepheshe batusa ukusebenzisa izinhlelo zokupholisa igesi.

Iyini inzuzo yokusika i-plasma?

Ngokuvamile, umncintiswano phakathi kobuchwepheshe bokusika izinto eziqinile kwenzeka emigomeni yokunemba nokusheshisa. Noma kunjalo, ukuvela kwezindlela ezintsha kuye kwandisa amandla okucubungula, futhi kwandisa izidingo eziyisisekelo zekhwalithi yokusebenza. Ngenxa yesethi yokusebenza kwemingcele, ukusika i-plasma ingenye yobuchwepheshe obunenzuzo kakhulu yalolu hlobo. Okokuqala, lokhu kubangelwa ukuthi kungenzeka ukuthi iphuzu lendawo lisikiwe ngaphandle kokuguqulwa kwendawo ezungezile. Ngisho nokusika insimbi engenasici nge-plasma kwenziwa ngaphandle kokuguquguquka okushisayo komsebenzi wokusebenza, nakuba kufanele kusetshenziswe izixhobo zamandla aphezulu ukucubungula izinto ezinjalo. Ngaphezu kwalokho, isivinini esikhulu sokusika sigcizelelwe. Uma ukhetha amandla afanele wamanje, bese ufaka ishidi elincanyana ongayisebenzisa ngendaba yamasekhondi ngaphandle kokulahlekelwa ngekhwalithi.

Yini okufanele ucabange ngokukhetha i-plasmorez?

Njengoba sekuphawuliwe, ekukhethweni kwedivayisi, amandla wamanje wezinsiza zibaluleke kakhulu, okuzovumela umuntu ukuba abhekane nesigaba esithile sensimbi. Isibonelo, amamodeli ama-40-50 amperes afaneleka ukusebenza ngethusi, ithusi, i-aluminium kanye nezinye izinsimbi ezingezona zensimbi, kodwa amandla abo akwanele ukusika okusezingeni eliphezulu nokuzethemba kwensimbi. Ukuze usebenze ngamamaki ensimbi omnyama, kuyadingeka ukuthi uqale ukuqondisa kumadivayisi anamandla wamanje okungenani angu-100 A. Futhi lokhu ngaphandle kokucabangela ubukhulu be-billet. Njengomthetho, ukusika kwe-plasma kwenziwa ngesilinganiso se-5 A nge-1 mm. Kufanelekile ukucubungula isikhathi sokusebenza komshini we-plasma. Ezingeni zezingeniso zokungena, isibonelo, lesi sikhashana angeke sibe ngaphezu kwemizuzu engu-10, emva kwalokho opharetha kufanele enze ikhefu lobuchwepheshe.

Isiphetho

Ngezo zonke izinzuzo zobuchwepheshe bokucubungula i-plasma, akuyona indlela engcono yokusika insimbi. Isibonelo, inqubo ye-hydroabrasive ibonakala ngekhono lokwenza amabhandeti cishe noma yikuphi ukuqina. Kulesi simo, imishini ishibhile ukugcina futhi idinga izindleko zamandla amancane. Futhi, ukusika kwe-plasma yensimbi inikeza isivinini esikhulu kanye nemfanelo ehambelana nomphumela. Okubaluleke kakhulu, inhlangano yobuchwepheshe yale nqubo ihilela kuphela ukuthengwa kwezixhobo ezikhethekile. Sebenzisa i-plasmapher efanayo nanoma ubani ekhaya - kodwa, eqinisweni, ngokulungiselela kahle. Uma kuqhathaniswa, umsebenzi wokuqeda awukwazi ukuwenza ngaphandle kokusebenzisa ama-aggregates amakhulu, ukuhambisa amajethi wamanzi noma umoya ngokuxubana nezinhlayiya zesihlabathi.
