Izinyathelo zokunciphisa amathuba okwehluleka kokuvinjwa kwe uhlelo lwesiqandisi

Kudingeka ukuthi zonke izingxenye ezihlanganisiwe nezishiselwe zalo lonke uhlelo lwesiqandisi se-industrial chiller kumele zihlanzwe. Lapho amapayipi e-welding, kuyadingeka ukuthi asheshe futhi anembile, ngoba uma kungekho ukuxhumana okuhle ngesikhathi sokushisela, ungqimba lwe-oxide odongeni lwangaphakathi lwepayipi luzowa kalula. Banga iphutha “lokuvinjwa okungcolile”. Ngaphezu kwalokho, kufanele kube nomhwamuko wamanzi emoyeni, futhi izinga lokushisa lokuqina lomhwamuko wamanzi lingama-degree angu-0, futhi lizoba yiqhwa emazingeni okushisa aphansi angaphansi kwama-degree angu-0. Ngakho-ke, uhlelo kufanele lukhishwe ngokuphelele ngaphambi kokugcwalisa uhlelo ngesiqandisi, futhi kuyadingeka Pump kuze kube yilapho ingcindezi esele ingaphansi -0.1MPa ukuvimbela ukuba khona komhwamuko wamanzi. Uma ingampontshelwa endaweni engenalutho engaphansi -0.1MPa, ijwayele ukwehluleka ukuvinjwa yiqhwa. Ukwengeza, ngemva kokufaka umshini wokomisa isihlungi, ungakhohlwa ukuthi umshini wokomisa isihlungi sokuqala kufanele ufakwe uqonde phezulu, futhi udinga ukujikeleziswa ngamadigri angu-90 ukuya phezulu, okuphumayo kuye phezulu. Lokhu kusebenza kusetshenziselwa ukuvimbela isihlungi kanye ne-capillary okubangelwa umthamo omkhulu nokungcola okukhulu. Ukuvinjwa.
