I-304L 316L ishubhu yokushintsha ukushisa yensimbi engagqwali

I-Heat Exchanger Basics:

Igobolondo nesishintshi sokushisa seshubhu wuhlobo olulodwa nje lomklamo wesishintshi sokushisa.Ifanele izicelo ezinengcindezi ephezulu kanye nezimakethe ezifana nalezi: ubisi, ukuphisa, isiphuzo, ukucubungula ukudla, ezolimo, ezemithi, i-bioprocessing, i-petroleum, i-petrochemical, i-pulp & paper, namandla namandla.

Njengoba igama layo lisho, lolu hlobo lokushintshanisa ukushisa luqukethe igobolondo elingaphandle, elenziwe (isitsha esikhulu sokucindezela noma indlu) enenqwaba yamashubhu obubanzi obuncane atholakala ngaphakathi kwezindlu zegobolondo.Olunye uhlobo loketshezi ludabula amashubhu obubanzi obuncane, kanti olunye uketshezi lugeleza phezu kwamashubhu (kulo lonke igobolondo) ukuze ludlulise ukushisa phakathi koketshezi olubili.Isethi yamashubhu ibizwa ngokuthi i-tube bundle, futhi ingase yakhiwe izinhlobo eziningana zamashubhu;eyindilinga, ephonswe ngobude, njll. kuye ngohlelo oluthile noketshezi oluhilelekile.

Kungase kube khona ukuhluka kwegobolondo ne-tube design.Ngokuvamile, iziphetho zeshubhu ngayinye zixhunywe kuma-plenums noma amabhokisi amanzi ngokusebenzisa izimbobo kuma-tubesheets.Amashubhu angase aqonde noma agobe amise u-U, abizwa ngokuthi ama-U-tubes.

Ukukhethwa kwempahla yokufaka amashubhu kubaluleke kakhulu.Ukuze ukwazi ukudlulisa ukushisa kahle, impahla ye-tube kufanele ibe ne-conductivity enhle yokushisa.Ngenxa yokuthi ukushisa kudluliselwa ohlangothini olushisayo kuya ohlangothini olubandayo ngamashubhu, kunomehluko wokushisa ngobubanzi bamashubhu.Ngenxa yokuthambekela kwe-tube material ekwandiseni ngokushisa okuhlukile emazingeni okushisa ahlukahlukene, ukucindezeleka okushisayo kwenzeka ngesikhathi sokusebenza.Lokhu kuyisengezo kunoma yikuphi ukucindezeleka okuvela ekucindezelweni okuphezulu okuvela emanzini ngokwawo.Okubalulekile kweshubhu kufanele kuhambisane nakho kokubili kwegobolondo noketshezi oluseceleni kweshubhu isikhathi eside ngaphansi kwezimo zokusebenza (izinga lokushisa, ukucindezela, i-pH, njll.) ukuze kuncishiswe ukuwohloka njengokugqwala.Zonke lezi zidingo zidinga ukukhethwa ngokucophelela kwezinto eziqinile, ezishisayo, ezimelana nokugqwala, nezisezingeni eliphezulu.Izinsimbi ezijwayelekile ezisetshenziswa ekukhiqizeni amashubhu okushintsha ukushisa zihlanganisa: insimbi ye-carbon, insimbi engagqwali (i-austenitic, i-duplex, i-ferritic, i-precipitation-hardable, i-martensitic), i-aluminium, i-alloy yethusi, i-alloy yethusi engeyona i-ferrous, i-Inconel, i-nickel, i-Hastelloy, i-tantalum, niobium, zirconium, titanium.
