ʻO ka koho kumu mua no nā pāpaʻi multistage kūpaʻa e pili ana i ke kaiapuni hana o ka pama a me nā waiwai o ka wai e puhi ʻia. Ma lalo iho nei kekahi mau koho mea hoʻoheheʻe multistage maʻamau, me kā lākou mau hiʻohiʻona a me nā hiʻohiʻona kūpono:
1. Ke kila kila:
Material:Hoʻohana pinepine ʻia nā kila kila Austenitic e like me 304 (0Cr18Ni9) a me 316 (0Cr18Ni12Mo2Ti).
Nā hiʻohiʻona:ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion, kūpono loa no ka hoʻoheheʻe ʻana i nā wai i loaʻa ka media corrosive haʻahaʻa.
Nā noi:Hoʻohana nui ʻia i ka hāʻawi wai, ka hoʻoulu ʻana i ka ʻoihana, ka lawe ʻana i ka wai ʻenehana, ka mālama wai, a me nā māla ʻē aʻe.
2. Hoolei hao:
Material:ʻO ka hao hina hina (HT) a me ka hao ductile (QT) ʻelua mau ʻano maʻamau.
Nā hiʻohiʻona:Hāʻawi ka hao hoʻoheheʻe maikaʻi i nā waiwai hoʻolei ʻana a me ke kūpaʻa ʻaʻahu, akā maikaʻi ʻole ka pale ʻana i ka corrosion.
Nā noi:Hoʻohana maʻamau no ka paila ʻana i ka wai maʻemaʻe a i ʻole ka media corrosive haʻahaʻa.
3. Hoolei kila:
Material:Ke ʻoi aku ka nui o ke kaomi ma mua o 1.6 MPa, hana pinepine ʻia nā ʻāpana amo -me ke kila hoʻolei ʻia, e like me ZG230-450.
Nā hiʻohiʻona:Hāʻawi ke kila kila i ka ikaika kiʻekiʻe a me ke kūpale ʻaʻahu, no laila kūpono ia no nā noi kiʻekiʻe -pilikia a ʻaʻahu-.
Noi:Hoʻohana maʻamau i nā ʻōnaehana ʻoihana pono e kū i nā kaomi kiʻekiʻe.
4. Ke kila kila kila:
Material:ʻO ke kila kalapona maʻamau (e like me Q235) a me -kiʻekiʻe kiʻekiʻe o ke kila kila (e like me 45 kila).
