Amakhasimende amaningi abika umsindo, intuthu, i-arc, nomhwamuko wensimbi lapho esebenzisa imishini yokusika i-plasma.Isimo sibucayi kakhulu lapho kusikwa noma kusikwa izinsimbi ezingenayo insimbi emisinga ephezulu, okubangela ukungcoliswa kwemvelo.Iningi labakhiqizi bemishini yokusika ye-CNC babamba iqhaza ethangini lokugcina amanzi ngaphansi kwebhentshi lokusebenzela ukugwema ukundiza kwe-soot.Pho wenza kanjani uthuli?Okulandelayo, ngizokutshela ngezinyathelo zayo zokususa uthuli.
Kumele kube nethangi lokugcina amanzi lokusika phezu kwamanzi.Ingaphezulu lethangi lamanzi liyitafula lomsebenzi wokubeka ucezu lokusebenza, futhi ubuningi bamalungu ensimbi ekhonjiwe ahleliwe, bese umsebenzi ocijile usekelwa endaweni evundlile ngamalungu ensimbi ecijile.Lapho ithoshi lisebenza, i-arc ye-plasma imbozwa ungqimba lwekhethini lamanzi, futhi ipompo ejikelezayo iyadingeka ukupompa amanzi ngaphandle kwechibi lamanzi bese ingena esibani.Lapho amanzi efafazwa kusukela kuthoshi lokusika, kwakhiwa ikhethini lamanzi elimbozwe i-arc plasma.Leli khethini lamanzi ligwema kakhulu ukulimala kwemvelo okubangelwa umsindo, intuthu, i-arc kanye nomhwamuko wensimbi okhiqizwa ngesikhathi sokusika.Ukugeleza kwamanzi okudingekayo ngale ndlela kungama-55 kuya ku-75 L/min.
Ukusika indawo engaphansi komhlaba ukubeka indawo yokusebenza cishe ngama-75mm ngaphansi kobuso bamanzi.Itafula okubekwa kulo i-workpiece liqukethe ilungu lensimbi elicijile.Inhloso yokukhetha ilungu lensimbi ecijile ukuhlinzeka itafula lokusika elinamandla okwanele ukuze lifake ama-chips kanye ne-slag.Lapho ithoshi yethulwa, ukugeleza kwamanzi acindezelwe kusetshenziselwa ukukhipha amanzi eduze kobuso bokuphela kwe-nozzle yethoshi, bese kubaselwa i-arc ye-plasma ukuze kusikwe.Lapho usika ngaphansi kwamanzi, gcina ukujula kwe-workpiece kufakwe ngaphansi kwamanzi.Uhlelo lokulawula izinga lamanzi kufanele lulungiswe, bese kwengezwa iphampu yamanzi kanye nethangi lokugcina amanzi ukuze kugcinwe izinga lamanzi ngokuchelela nokukhipha amanzi.Ngokuvamile, umshini wokusika we-plasma we-manual noma i-othomathikhi yokusika i-workbench ifakwe i-exhaust system ezungeze ibhentshi lokusebenzela ukudweba igesi yokukhipha ngaphandle kwesitolo somsebenzi.Nokho, igesi ephumayo isangcolisa imvelo.Uma ukungcola okudaliwe kudlula izinga likazwelonke, intuthu nempahla yokuguqula uthuli kufanele yengezwe.
Ukwelashwa kwe-exhaust ngokuvamile okwengxenye yendawo esikiwe kuphela.Iyunithi yesiphephetha-moya esivamile sakhiwe ihood yokuqoqa igesi, ipayipi, isistimu yokuhlanza kanye nefeni.Ingxenye ye-exhaust ingahlukaniswa ibe isistimu ye-exhaust eyingxenye engaguquki kanye nesistimu yokukhipha ingxenye yeselula ngokuya ngezindlela ezahlukene zokuqoqa igesi.Uhlelo lwe-fixed part exhaust lusetshenziselwa ikakhulukazi indawo yokusebenzela yokukhiqiza yokusika ye-CNC enkulu enekheli elimisiwe lokusebenza kanye nendlela yokusebenza yabasebenzi.Isikhundla se-hood yokuqoqa igesi singalungiswa ngesikhathi esisodwa ngokusho kwesimo sangempela.Ingxenye ehambayo yesistimu yokukhipha umoya ibucayi, futhi izimo zokusebenza ezihlukene zingakhethwa ngokuvumelana nezimo zokusebenza ezihlukene.Uhlelo lokuhlanza lwe-CNC yokusika insipho namagesi ayingozi ngokuvamile amukela uhlobo lwesikhwama noma inhlanganisela yokususwa kothuli lwe-electrostatic kanye nendlela yokuhlanza i-adsorbent, enamandla amakhulu okucubungula nezimo zokusebenza ezizinzile.
