Ukushisela i-Adiabatic kuyindlela ethandwayo esetshenziswa ezimbonini eziningi lapho kudingeka khona ukuhlanganiswa kwezinsimbi okunembile nokuphumelelayo. Kodwa-ke, enye yezinselele ezinkulu kule nqubo ukukhiqizwa kokushisa okweqile, okungathinta ubuqotho bejoyinti elishiselwe. Ukuze kuxazululwe le nkinga, ukupholisa i-adiabatic weld okusheshayo nokulula kuye kwavela njengesixazululo esithembekile. Kulesi sihloko, sixoxa ngezici nezinzuzo zale ndlela yokupholisa futhi sihlole imikhiqizo eyenza kube lula ukuyisebenzisa.
Ukupholisa okusheshayo nokulula kwe-weld ye-adiabatic kunciphisa kakhulu isikhathi sokupholisa esidingekayo endaweni ehlanganisiwe. Ukushisa okweqile okukhiqizwa ngesikhathi senqubo yokushisela kuqedwa ngokushesha ngokusebenzisa ubuchwepheshe obukhethekile bokupholisa, okuqinisekisa ubuqotho namandla ejoyinti elihlanganisiwe. Le ndlela yokupholisa inikeza izinzuzo eziningana njengokukhiqiza okwandisiwe, ukunciphisa ukuphambuka ngemva kokushisela, ikhwalithi iyonke ethuthukisiwe yenqubo yokushisela, kanye nokuphepha okwandisiwe kwabashiseli.
Umkhiqizo owodwa osiza ukupholisa okusheshayo nokulula kokushisela kwe-adiabatic yi-Welding Insulated Gas Cylinders. Isilinda samukela ukwakheka kwesakhiwo esinezingqimba ezimbili, esakhiwe yithangi langaphakathi nethangi langaphandle, futhi sinengqimba yokuvimbela ukushisa. Sisebenzisa izinto zokuvimbela ukushisa ezinezingqimba eziningi ukugcina i-vacuum ephezulu, sisetshenziselwa ukuthutha nokugcina umoya-mpilo, i-nitrogen ewuketshezi, i-argon ewuketshezi kanye nezinye izinto eziwuketshezi.
Amasilinda egesi okuvikela ukushisela atholakala kumamodeli ahlukene ukuze ahlangabezane nezidingo ezahlukene zohlelo lokusebenza. Ngokusho kokucindezela okuhleliwe kwevalvu yokuphepha, ihlukaniswe ngokucindezela okuphakathi (MP) kanye nokucindezela okuphezulu (P). Ngaphezu kwalokho, kukhona uhlobo lokucindezela okuphezulu kakhulu (VEP), oluvame ukusetshenziswa ezinhlotsheni zohlelo lokusebenza ezibandakanya ukucindezela okuphakathi kanye nokucindezela okuphezulu. Lolu hlobo luqinisekisa ukuthi amasilinda angahlinzeka ngempumelelo kokubili amagesi oketshezi kanye negesi ngezidingo ezahlukene zokushisela.
Kunezinzuzo eziningi zokusebenzisa amasilinda egesi afakwe i-welded insulating. Ukwakhiwa kwawo okunezingqimba ezimbili okufakwe i-thermal insulation kusiza ukugcina izinga lokushisa legesi egciniwe, kuvimbele noma yiziphi izinguquko ezingathandeki ezingathinta inqubo yokushisela. I-vacuum ephezulu egcinwe ngaphakathi kwesilinda iqinisekisa ubumsulwa nokuzinza koketshezi olugciniwe, okuholela ekusebenzeni kwe-welding okuthembekile nokuqhubekayo.
Ngaphezu kwalokho, ukupholisa okusheshayo nokulula okufinyelelwa yilo mkhiqizo kunciphisa kakhulu isikhathi sokungasebenzi phakathi kokusebenza kokushisela. Uma ukushisa okweqile kunyamalala ngokushesha, abashisela bangadlulela ngokushesha endaweni elandelayo, bandise umkhiqizo jikelele. Isikhathi sokupholisa esincishisiwe sinciphisa nokuphambuka ngemva kokushisela ukuze kube nemiphumela eqondile yokushisela. Ngaphezu kwalokho, le ndlela yokupholisa inciphisa ukuvezwa komshisela ekushiseni okukhulu, yandisa ukuphepha komshisela.
Ekuphetheni, ukupholisa okusheshayo nokulula kwama-weld e-adiabatic kubalulekile ukuze kufezwe ama-weld asezingeni eliphezulu ngaphandle kokuphazamisa ubuqotho namandla amalunga. Amasilinda egesi afakwe i-insulation ahlanganisiwe ayimikhiqizo efinyelela le ndlela yokupholisa ngokwakhiwa okunezingqimba ezimbili, ukuvikela ukushisa, kanye nokugcinwa kwe-vacuum ephezulu. Amandla ayo okugcina nokuthutha amagesi aketshezi kanye namagesi kuyenza ifaneleke ezinhlotsheni ezahlukene zezicelo zokushisela. Ukusebenzisa amasu okupholisa asheshayo nalula akugcini nje ngokukhulisa umkhiqizo, kodwa futhi kuthuthukisa imiphumela yokushisela iyonke futhi kuqinisekisa ukuphepha kwabashiseli.
