Uxinzelelo oluphezulu oluxhathisa umenzi wetyhubhu yebhoyila yokwenyani
Iityhubhu zebhoyila ezinoxinzelelo oluphakathi kunye noxinzelelo oluphantsi zikumgangatho ophezulu wekhabhoni yolwakhiwo lwentsimbi eshushu-eqengqelekayo kwaye ebandayo ezotyiweyo (eqengqelekayo) iityhubhu ezingenamthungo ezisetyenziselwa ukwenza iityhubhu zomphunga oshushu kakhulu, iityhubhu eziqengqelekayo kwizibiyila zoxinzelelo oluphantsi naphakathi lwezakhiwo ezahlukeneyo, iityhubhu zomphunga ezishushu kakhulu, iityhubhu ezinkulu zomsi. , iityhubhu ezincinci zomsi kunye neetyhubhu zezitena ze-arch kwiibhoyili ze-locomotive. Isetyenziswa ikakhulu kwimibhobho ehambisa ulwelo oluphantsi kunye noxinzelelo oluphakathi kwiibhoyila zoshishino kunye neebhoyila zasekhaya. Izinto ezimele ziyi-10 kunye ne-20 yentsimbi.
Umbhobho we-boiler luhlobo lwetyhubhu engenamthungo. Indlela yokuvelisa iyafana neyombhobho ongenamthungo, kodwa kukho iimfuno ezingqongqo kwibakala lensimbi elisetyenziselwa ukwenziwa kombhobho wensimbi. Ngokutsho kobushushu benkonzo, yahlulwe ibe ityhubhu yebhoyila ngokubanzi kunye netyhubhu yebhoyila yoxinzelelo oluphezulu.
Ipropathi yomatshini wetyhubhu yebhoyila isalathiso esibalulekileyo sokuqinisekisa ukusebenza kokugqibela kwenkonzo (ipropathi yomatshini) yentsimbi, exhomekeke kukwakheka kweekhemikhali kunye nenkqubo yokunyanga ukushisa kwentsimbi. Kwinqanaba lombhobho wensimbi, ngokweemfuno ezahlukeneyo zenkonzo, iimpawu zokuqina (amandla okuqina, amandla emveliso okanye indawo yokuvunwa, i-elongation), izinkomba zobunzima kunye nokuqina, kunye neempawu zokushisa eziphezulu kunye eziphantsi ezifunwa ngabasebenzisi zichazwe.
① Ngokuqhelekileyo, ubushushu benkonzo yeetyhubhu zebhoyila bungaphantsi kwama-350 ℃, kwaye iityhubhu zasekhaya zenziwe ikakhulu ngeNombolo ye-10 kunye neNombolo ye-20 yesakhiwo se-carbon steel iityhubhu ezishushu eziqengqelekayo okanye iityhubhu ezitsalwa ngokubanda.
②Iityhubhu zebhoyila ezinoxinzelelo oluphezulu zihlala zikwiqondo lobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. Imibhobho iya kuba yi-oxidized kwaye i-corrode phantsi kwesenzo segesi ephezulu ye-flue flue kunye ne-steam. Umbhobho wensimbi kufuneka ube namandla aphezulu, i-anti-oxidation ephezulu kunye nokusebenza kwe-corrosion kunye nokuzinza okulungileyo kwesakhiwo.
① Iityhubhu zebhoyila ngokubanzi zisetyenziswa ikakhulu ukwenza iityhubhu zodonga lwamanzi, iityhubhu zamanzi abilayo, iityhubhu zomphunga oshushu kakhulu, iityhubhu zomphunga ezishushu kakhulu kwiibhoyila zikaloliwe, iityhubhu ezinkulu nezincinci zomsi kunye neetyhubhu zezitena zearch.
②Iityhubhu zebhoyila ezinoxinzelelo oluphezulu zisetyenziswa ikakhulu ukwenza iityhubhu zokufudumeza, iityhubhu zokufudumeza, iityhubhu zomoya, iityhubhu eziphambili zomphunga, njl. Unikezelo kunye nemfuno yoshishino lwetyhubhu yebhoyila yoxinzelelo oluphezulu luzinzile jikelele, kodwa unikezelo kunye nemeko yemfuno yoshishino oluncinci ngalunye luya kwahlulwa ngakumbi. Abangaphakathi babonise ukuba ikhonkco elibaluleke kakhulu kukusetyenziswa kunye nokukhuthaza ukugcinwa kwamandla amatsha kunye ne-thermal insulation 20g izixhobo ze-tube yebhoyili ephezulu yoxinzelelo.
Iimveliso zetyhubhu yebhoyila yoxinzelelo olutsha i-20g yoxinzelelo oluphezulu iyanda ngokuthe ngcembe emarikeni, njengeengubo eziluhlaza zokhuselo lokusingqongileyo, ukonga umbane kunye nokugcinwa kwamanzi kwiimveliso zococeko, amatye okhuselo lokusingqongileyo, ukhuseleko lokusingqongileyo ibhodi yokugquma ugwebu lwesamente yangaphandle, njl.njl. ithemba lokonga umbane kunye neemveliso zokhuseleko lokusingqongileyo kwimarike ebanzi ye-20g kushishino lwetyhubhu yoxinzelelo oluphezulu luyathembisa[1]
(1)I-GB / t5310-2008 iityhubhu zentsimbi ezingenamthungo kwiibhoyili zoxinzelelo oluphezulu. Indlela yokuvavanya ukwakheka kweekhemikhali iya kuhambelana neendawo ezifanelekileyo kwi-gb222-84, iindlela zokuhlalutya iikhemikhali zentsimbi, intsimbi kunye nealloy kunye neendlela ze-gb223 zokuhlalutya iikhemikhali zentsimbi, intsimbi kunye nealloy.
(2) Ukwakhiwa kweekhemikhali zemibhobho yensimbi yebhoyili ephuma ngaphandle iya kuhlolwa ngokwemigangatho efanelekileyo echazwe kwisivumelwano.
