ʻO ke koho ʻana i nā mea no nā paipu spiral (core heat exchange element) o kahi mea hoʻololi wela. Pono e hāʻawi ʻia ka mea nui i ke kaulike ʻana i ka pale ʻana i ka corrosion, conductivity thermal, a me ka ikaika kūkulu. ʻO kēia ka wehewehe kikoʻī o ka hoʻohui ʻana i nā mea maʻamau, nā waiwai, a me nā hiʻohiʻona kūpono.
Mea Maʻamau i hoʻohana ʻia (E pili ana i nā kūlana hana maʻamau)
1. Nā hiʻohiʻona kumu o ke kila kalapona (Q235, 20 # kila):
He kiʻekiʻe kona hoʻoili wela (ma kahi o 45 W/(m·K)), haʻahaʻa kumu kūʻai, maʻalahi ka hana a me ka hoʻoheheʻe ʻana, a me ka ikaika o ke kūkulu ʻana;
2. Ke kila kila (304, 316L, 321) Nā hiʻohiʻona nui:
ʻO ke kūpaʻa ʻino kiʻekiʻe (304 kūpaʻa i ka ʻino nāwaliwali, 316L kūpaʻa i ka corrosion ikaika, loaʻa ka molybdenum, 321 kū i ka intergranular corrosion); ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa (304 ma kahi o 16 W/(m・K), haʻahaʻa iki ma mua o ke kila kalapona), kūpaʻa wela kiʻekiʻe (ka mahana hana mau ʻAʻole a like paha me 600 degere ), maʻalahi e hoʻomaʻemaʻe, kū i nā kūlana hoʻomaʻemaʻe meaʻai/lāʻau; ʻOi aku ke kumu kūʻai ma mua o ke kila kalapona, nā koi kaʻina hana kuʻi maʻalahi.
ʻO nā mea hana kiʻekiʻe-kuʻe i ka ʻino (kūpono no nā kūlana hana ʻino loa)
1. Nā huila Titanium (TA1, TA2)
ʻO nā hiʻohiʻona kumu: He kūpaʻa ikaika loa ia (hiki iā ia ke kū i ka ʻaneʻi āpau a me nā media alkali, me ka waika hydrochloric concentrated, sulfuric acid, chlor -alkali solution, a me ka wai kai), a ʻaʻohe pilikia o ka ʻāʻī ʻana a i ʻole ka ʻāʻī ʻana.
2. Hastelloy (C-276, C-22) Nā hiʻohiʻona nui:
ʻO ke kila ultra{1}}ʻeleʻele ʻeleʻele (kū kūʻē i nā ʻakika oxidizing, nā ʻakika hoʻemi, fluorine/chlorine-mea paʻa i loko, a me -ka wela wela); ʻO ke kūpaʻa wela kiʻekiʻe (emi a like paha me 800 degere), ikaika kiʻekiʻe, kūpono no nā kūlana hana koʻikoʻi; ʻO ke kumu kūʻai kiʻekiʻe loa (ma kahi o 1.5-2 mau manawa o ka titanium alloys), a paʻakikī ke hana.
3. Copper a me ke keleawe (copper T2 maʻemaʻe, keleawe H68, cupronickel B30) Nā hiʻohiʻona nui:
ʻOi aku ka nui o ka hoʻoili wela (ma kahi o 401 W/(m·K) no ke keleawe, ʻoi aku ma mua o 20 mau manawa o ke kila kuhili ʻole), ka hopena i ka maikaʻi o ka hoʻololi wela; 'O ke keleawe 'ano 'ino 'ino (kūpono no ka mea ho'ohehe'e 'ole me ka oxidation), he ha'aha'a ha'aha'a ke kūpale 'ino ke keleawe, a 'o ka cupronickel (keleawe - alloy nickel) 'a'ole ia i ka wai kai a me ka chlorine -i loko o ka media corrosion; ʻO ke kumu kūʻai maʻalahi (ʻoi aku ka kiʻekiʻe ma mua o ke kila kalapona, haʻahaʻa ma mua o ke kila kila), a maʻalahi hoʻi e hana a piʻo (kūpono no ka wili spiral).
Inā makemake ʻoe e ʻike hou aku e pili ana i nā ʻāpana hoʻololi wela a makemake paha e kūʻai, e ʻoluʻolu e hoʻouna i leka uila iā 9988xiaoshuai@gmail.com, e pane mākou iā ʻoe ma hope o ka ʻike ʻana i ka leka!
Hui ʻoihana
Ua lako kā mākou hui me kahi hui lawelawe -kiʻekiʻe ma hope o-kūʻai me nā limahana ʻenehana ke kumu, a e hāʻawi i nā manaʻo manaʻo kūpono i ka wā e loaʻa ai nā leka hoʻomaopopo lawelawe mai nā mea hoʻohana.
7x24 Nā lawelawe ʻenehana
Hāʻawi kā mākou hui i ke kākoʻo ʻenehana manuahi no nā huahana a mākou e kūʻai aku ai a hoʻonohonoho i ka hoʻomaʻamaʻa ʻenehana no nā limahana kūpono.
