No ka hana pinepine ʻana i ka hana ʻana i ka cavitation pamu

ʻO nā mea hana mea hana pāpaʻi slurry: pono ke koho ʻana i ka pauma i ka mea? ʻO ke kūʻē ʻana i ka ʻinoʻino ʻana e ka poʻe ʻilihune i ka hoʻonohonoho maikaʻi ʻana penei: 12% Cr steels <17% Cr steel Stress corrosion ʻO ke koʻikoʻi koʻikoʻi e pili ana i kahi ʻino a me ka ʻino ma lalo o ke koʻikoʻi i hoʻokumu ʻia e ka pilina o ke kaiapuni. ʻOi aku ka maʻalahi o nā kila Austenitic CrNi i ka corrosion koʻikoʻi ma Cl medium. Me ka maʻiʻo Cl, ka mahana a me ke koʻikoʻi i ʻoi aku ka maʻalahi o ka corrosion stress. Nui ʻO ka 70 ~ 80 ℃ ma hope me ka ʻole o ke koʻikoʻi corrosion slurry pump mea hana. ʻO nā ana e pale aku ai i ka corrosion koʻikoʻi ke kiʻekiʻe Ni maʻiʻo (Ni> 25% ~ 30%) Cr ˉ Ni austenitic steel waha Kuhiliʻole kila slurry pump mea hana.

ʻO ka ʻino a me ka ʻaʻahu e pili ana i ka wai holo wikiwiki ma luna o ka ʻili metala. ʻAʻole e like me ka abrasive fluid erosion corrosion a me ka ʻaʻahu i hoʻokumu ʻia e ka mea waena. ʻOkoʻa nā mea ʻokoʻa i ka corrosion a ʻaʻahu kūʻē. ʻO ke kūpaʻa abrasion i ka ʻino ma ka ʻokoʻa ma waena o kahi huli maikaʻi: ferritic austenitic – ferritic steel < austenitic steels.

ʻAi ʻino ʻino ʻia ʻo Cavitation i ka wā i kapa ʻia ai ka pauma cavitation erosion ma muli o ka ʻino. Kāohi i ka ʻino o ka cavitation o ke ʻano hana maʻalahi a maʻalahi ka cavitation. No ka hana pinepine ʻana i ka hana ʻana i ka cavitation pump, i mea e pale ai i ka corrosion cavitation, hiki ke hoʻohana ʻia nā mea cavitation-resistant,mea hana pahū slurrygula, keleawe phosphor, kila kuhiliʻole, 12% kila chromium. ʻO kaʻoiaʻiʻo, ʻo ka pōʻino o ka corrosion ka hopena o ka hopena hui o nā ʻano ʻano corrosion, i ka consolidation selection factor. ʻO ka lua, ʻo ka mea metala o ka paila a me nā ʻano koho 1 Mea .`

Nui nā mea e pauma. ʻO nā mea metala maʻamau he hao hao, kila kila, 12% chromium steels, austenitic stainless steel 316L stainless aluminika a pēlā aku. Eia kekahi, aia kahi mea hao silika kiʻekiʻe no ka media corrosive , № Re ⒍ st, Monel , B, Hastelloy C, 904, CD4MCu, titanium , titanium alloy.

ʻO ka hui kemika maʻamau o ka mea hoʻoheheʻe ʻia he pauma maʻamau me nā mea kōkua non-metallic: Teflon , nitrile rubber, chloroprene rubber, fluorine rubber, synthetic rubber, a me FFKM , graphite, aniani fiber piha PTFE a me nā mea like.
