Okujwayelekile: ASTM A179--------Izinga Lenhlangano YaseMelika Yokuhlola Nezinto Zokusebenza
Isetshenziselwa isishintshi sokushisa esinamapayipi, i-condenser kanye nemishini efanayo yokudlulisa ukushisa
Amabanga Ethubhu Yensimbi Eyinhloko: A179
Okujwayelekile :ASTM A192-------Izinga Lenhlangano YaseMelika Yokuhlola Nezinto Zokusebenza
Isetshenziselwa ukucindezela okuphezulu kwe-min.Wall ukujiya kwe-carbon steel Boiler kanye neshubhu ye-Superheater
Amabanga Ethubhu Yensimbi Eyinhloko: A192
Amashubhu e-boiler angamashubhu angenamthungo futhi enziwe nge-carbon steel noma i-alloy steel.Asetshenziswa kakhulu kuma-boilers we-steam, ukukhiqiza amandla, ezitshalweni zikaphethiloli wezinto ezimbiwa phansi, ezimbonini zokucubungula izimboni, izitshalo zamandla kagesi, njll. Amashubhu e-boiler angaba ipayipi le-boiler yokucindezela okuphakathi noma ipayipi le-boiler yokucindezela okuphezulu.
Amashubhu e-boiler avame ukukhiqizwa ngezinqubo ezingenamthungo.Nansi i-akhawunti enemininingwane yokuthi zenziwa kanjani:
Enziwa Kanjani Amashubhu Boiler?
Kokubili amashubhu kabhayela anomfutho ophakathi nendawo nophezulu enza inqubo efanayo yokuqala yokukhiqiza, ehlanganisa ukudweba okuhle, ukukhanya kwendawo, ukugingqika okushisayo, ukudonswa kubanda kanye nokwanda kokushisa.Kodwa-ke, izinyathelo ezilandelayo zenziwa ukwenza amapayipi anengcindezi ephezulu aqine futhi amelane kakhulu.
Ukwelashwa kokushisa kuhlanganisa ukushisisa nokupholisa amapayipi kabhayela anomfutho ophezulu okwandisa ukuqina, ukuqina kanye nokungagugi.Izinyathelo ezehlukene eziza ngaphansi kokwelashwa kokushisa zifaka ukucisha, ukufuthelana kanye nokudonsa.
Ukucisha kwenziwa ukuze kwandiswe ubulukhuni beshubhu lebhayela elinomfutho ophezulu.Ipayipi lishiselwa ngokulinganayo libe ezingeni lokushisa elifanele bese licwiliswa ngokushesha emanzini noma emafutheni ukuze liphole ngokushesha.Lokhu kulandelwa ukupholisa emoyeni noma endaweni eqandayo.
I-Tempering isetshenziselwa ukususa i-brittleness epayipini.Ukucisha kungabangela ukuthi ipayipi licishwe noma liphuke.
I-Annealing ingasusa ukucindezeleka kwangaphakathi kupayipi.Kule nqubo, ishubhu elingenamthungo lishiselwa kuzinga lokushisa elibucayi bese lishiywa ukuze liphole kancane emlotheni noma kumcako.
Ukususwa kokugqwala kwe-Boiler Tube
Kunezindlela eziningana zokususa ukugqwala ku-boiler tube, okulula kakhulu ukuhlanza usebenzisa i-solvent ne-emulsion.Nokho, lokhu kungasusa uthuli kuphela, uwoyela, njll. kodwa ngeke kususe ipayipi ngokuphelele izinsalela zezinto eziphilayo.
Indlela yesibili ukususa ukugqwala kusetshenziswa amathuluzi okwenziwa ngesandla noma amandla.Ukuhlanza amathuluzi kungasusa izimbobo ze-oxide, i-welding slag nokugqwala.
Indlela ejwayeleke kakhulu ukusebenzisa izindlela zamakhemikhali ne-electrolytic, ezaziwa nangokuthi ukuhlanza i-asidi.
Ukukhipha ukugqwala kokufutha kuyindlela ekahle kakhulu yokuhlanza ishubhu likabhayela njengoba kungasusa ukungcola, i-oxide nokugqwala kuye ezingeni elikhulu.Ngaphezu kwalokho, kungandisa ubulukhuni bepayipi.
Ngenkathi ukhetha amashubhu obhayela, bheka okulandelayo ukuze ukhethe amashubhu alungile nasezingeni elihle:
1. Bheka ingxenye enqamulayo yeshubhu.Ishubhu elingenamthungo lekhwalithi elihle lizoba nesiphambano esibushelelezi futhi ngeke libe namaqhubu nokungahambi kahle.
2. Hlola ukuminyana kwepayipi ukuze uqonde amaphesenti okungcola okusepayipini.Uma ipayipi libonisa ukuminyana okuphansi, gwema!
3. Qiniseka ukuthi uyaluhlola uphawu lokuhweba.Abakhiqizi abahlonishwayo bahlala bebeka uphawu lwabo lokuthengisa kumashubhu abo angenamthungo.
4. Hlola ubuso be-boiler tube.Ishubhu yeboiler yekhwalithi enhle izoba nendawo ebushelelezi.Uma uthola indawo engaphezulu ilukhuni futhi ingalingani, ungaqiniseka ukuthi ikhwalithi ayifinyelele kumaki.
