Injongo yokutshintsha i-cylinder ye-Dewar nge-nitrogen ngexesha lokuvala

I-Welding Dewar Cylinds itshintshwe nge-nitrogen ngexesha lokuvalwa, nto leyo emiselweyo ziimpawu ze-nitrogen. Xa kuthelekiswa nomoya jikelele, igesi ye-nitrogen ephezulu yeoksijini-engenamanzi kunye ne-oyile, ukuqhutywa kwe-oyile kuncitshisiwe, kwaye kuncitshiswe umgangatho wokufakelwa kobushushu.

1. Itanki yangaphakathi ishushu ngama-250 degrees ukuba ikhuphe, ikakhulu ukuvumela umoya ngaphakathi ukuba uvuthelwe ngokupheleleyo ukuba uvuthiwe, kwaye umoya unokukhutshwa kwindawo ephezulu emva kokupholisa.

2. Ukuba inqanaba lenkqubo yokukhutshelo kunye nenkqubo ye-welding iphezulu kakhulu, kunokwenzeka ukuba iqinisekiswe ukuba i-vacuum ayigutyungelwanga kwaye ingagcwaliswanga yi-vacum, kuba iphinde ihamba kancinci kwaye inokuthi ihambelane neemfuno zokufakwa kwesivumelwano.I-3. Ukugcwaliswa kwe-nitrogen ikakhulu kusetyenziswa ikakhulu kwimbuyekezo xa iinkqubo ezi-2 zingentla. Ngalo lonke inkqubo 1 ivela kwiibhotile ezili-10, kufuneka izaliswe yi-nitrogen. Emva kokugcwalisa i-nitrogen, ingcinezelo kwibhotile isondele kwingcinezelo eqhelekileyo, ukuze imeko ye-Welding ye-Welding, umoya awuyi kugcinwa kwinqanaba lokufumana indawo yokuqala yokwandiswa komhlaba kunye nokuphumelela okuphantsi kwengqondo. I-insulid.

I-4. Inkqubo ye-welding yeyona ngxaki iphambili. Ukuba umgangatho we-welding akwanele, ngexesha lokusetyenziswa kwetanki yokupheka, ngenxa yokwanda kunye nokuntywila kobushushu, i-nitrogen iya kuphuma i-cylinder xa ivuza ngexesha lokupholisa. Emva kwexesha elide lokusetyenziswa, i-nitrogen iya kuthathelwa indawo ngumoya, ukuze ilahleko ye-cylinder yentsebenzo yokufakelwa kwe-intermal ingenisa ngokulula iziqhushumbisi.
