Umtshintshisi wobushushu sisixhobo sokudlulisa ubushushu esisetyenziselwa ukugqithisela amandla angaphakathi e-thermal phakathi kolwelo ezimbini okanye ngaphezulu ezikhoyo kumaqondo obushushu ahlukeneyo.Ityhubhu okanye ityhubhu yinxalenye ebalulekileyo yesixhobo sokukhupha ubushushu, apho ulwelo luhamba khona.Ekubeni izitshintshi zobushushu zinokusetyenziswa kwinkqubo, amandla, i-petroleum, uthutho, i-air conditioning, ifriji, i-cryogenic, ukubuyisela ubushushu, enye i-fuel, kunye namanye amashishini, iityhubhu zokutshintsha ubushushu zinokuhlelwa ngokufanelekileyo njengeityhubhu zeeradiator, ii-regenerators, condensers, ii-superheaters. , izifudumezi, izipholisi, izifudumezi, kunye nezibiyitha.Iityhubhu zokutshintsha ubushushu zinokufakwa ngohlobo oluthe tye, uhlobo olugobe u-U, uhlobo olujijekileyo, okanye uhlobo lwenyoka.Ngokubanzi, azinamthungo okanye iityhubhu ezidityanisiweyo ezifumaneka kumda wangaphandle phakathi kwe-12.7 mm kunye ne-60.3 mm ezinodonga olubhityileyo.Iityhubhu zivame ukudibaniswa kunye ne-tubesheet nge-rolling okanye inkqubo ye-welding.Kwezinye iimeko, ityhubhu ye-capillary okanye i-tubing-diameter enkulu iyasebenza.Ityhubhu inokunikezelwa ngamaphiko (ityhubhu ecikizekileyo) ebonelela ngokusebenza ngokufanelekileyo kokugqithisela ubushushu.
1. UKhetho lweMathiriyeli yeTubhing yokuTshintsha ubushushu
Kumsebenzi wobunjineli, ukukhethwa kwezixhobo zetyhubhu yokutshintsha ubushushu kuya kuqhutywa ngokungqongqo.Ngokubanzi, iityhubhu iya kuhambelana nemigaqo enikwe kwiBoiler ye-ASME kunye neKhowudi yeVessel yoxinzelelo lweCandelo II.Ukukhethwa kwezinto eziphathekayo kuya kusekelwa kuqwalaselo olupheleleyo kunye nokubalwa koxinzelelo lokusebenza, ubushushu, izinga lokuhamba, ukubola, ukukhukuliseka, ukusetyenzwa, ukusebenza kakuhle kweendleko, i-viscosity, uyilo, kunye nezinye iimeko.Ngokuqhelekileyo, i-tubhing yokutshintshiselana kobushushu inokunikezelwa kwizinto zetsimbi ze-ferrous okanye ezingenayo, ezinokuphinda zichazwe njenge-carbon steel, i-alloy iron ephantsi, insimbi engenasici, i-duplex stainless steel, i-nickel alloy, i-titanium alloy, i-alloy yobhedu, i-alloy ye-aluminium, i-tantalum kunye zirconium, njl.
Iimpawu eziqhelekileyo zezixhobo ziquka: ASTM A178, A179, A209, A210, A213, A214, A249, A250, A268, A334, A423, A450, A789, A790, A803, A1016;ASTM B75, B111, B135, B161, B165, B167, B210, B221, B234, B251, B315, B338, B359, B395, B407, B423, B444, B466, B455, B3 B3 B1 622 .B626, B668, B674, B676, B677, B690, B704, B729, B751 kunye neB829.Ukwakhiwa kweekhemikhali, iipropati zomatshini kunye nokuphathwa kobushushu zonke ziya kuhambelana nemigangatho ekhankanywe ngasentla ngokulandelelanayo.Ityhubhu yokutshintsha ubushushu inokuveliswa ngenkqubo eshushu okanye ebandayo.Ngaphezu koko, inkqubo yokusebenza eshushu ivelisa ifilimu ebhityileyo kunye nerhabaxa emnyama ye-iron oxide yentsimbi kumphezulu wayo.Olu hlobo lwefilimu luhlala lubizwa ngokuba "yisikali sokugaya" esiya kuthi emva koko sisuswe ngokujika, ukupolisha, okanye inkqubo yokuchola.
2. Uvavanyo kunye noHlolo
Uvavanyo olusemgangathweni kunye nokuhlolwa kwiityhubhu zokutshintshiselana ngobushushu ngokuqhelekileyo kubandakanya uvavanyo olubonakalayo, ukuhlolwa komda, uvavanyo lwangoku lwe-eddy, uvavanyo loxinzelelo lwe-hydrostatic, uvavanyo lomoya ophantsi kwamanzi, uvavanyo lwemagnethi, uvavanyo lwe-ultrasonic, uvavanyo lomhlwa, uvavanyo lomatshini (kubandakanya ukuqina, ukuvutha, ukucaba, kunye nokuvavanya ukuguqulwa kwe-flattening), uhlalutyo lweekhemikhali (PMI), kunye nokuhlolwa kwe-X-ray kwii-welds (ukuba zikhona).
