ʻO ka hoʻohaʻahaʻa ʻana a i ʻole ka hana ʻole ʻia e ka luhi, corrosion, aahu a me ka cavitation e alakaʻi i nā kumukūʻai kiʻekiʻe o ka hana a me ka mālama ʻana no ka axial. pahu moku nā pāpaʻi. I ka hapanui o nā hihia, hiki ke pale ʻia kēia mau pilikia ma ke koho ʻana i nā mea pono.

ʻO nā helu ʻehā ma lalo nei nā pae hoʻohālikelike no ke koho ʻana i nā mea noaxial split case pumpsi nā kahe kahe kiʻekiʻe:

1. Ma muli o ke kahe kiʻekiʻe o ka pāpaʻi, ʻo ka ikaika o ka luhi (ʻo ka mea maʻamau i loko o kahi ʻano corrosive) pili pili loa i nā aʻaʻa kaomi, ka hoʻopiʻi a me ke kuʻekuʻe a me nā koʻikoʻi hoʻololi.

2. ʻO ka ʻinoʻino ma muli o ka nui o ke kahe ʻana, ʻoi aku ka ʻino.

3. Cavitation

4. ʻO ka ʻaʻahu ma muli o nā ʻāpana paʻa i hoʻokomo ʻia i loko o ka wai.

ʻO ka ʻaʻahu a me ka cavitation ka mea nui o ka ʻaʻahu mechanical, i kekahi manawa e hoʻoikaika ʻia e ka corrosion. ʻO ka corrosion ka hui pū ʻana o nā hopena kemika ma waena o nā metala, ka pāpaʻi pahū, ka oxygen a me nā mea kemika. Aia kēia pane i nā manawa a pau, ʻoiai inā ʻaʻole i ʻike ʻia. Eia kekahi, ua kaupalena ʻia ka wikiwiki o ka impeller tip e ka hydraulic, vibration a me nā koi noise.

ʻO nā mea metala maʻamau i hoʻohana ʻia i nā pahu pahu axial split penei:

Ka hao - nawaliwali i ke kapa komo

Ke kila kalapona - hoʻohana ʻia i ka wai me ka ʻole o ka oxygen a me nā corrosive

Ke kila kila haʻahaʻa - ʻaʻole hiki ke hoʻopaʻa ʻia

Ke kila Martensitic - kūpono no ka wai maʻemaʻe a i ʻole ka wai palupalu

Austenitic kila - maikaʻi ke kū'ē i kaʻaʻahuʻaʻahu a me ka erosion

Duplex steel - hiki ke pale i ka corrosion kiʻekiʻe

Pono nā mea hoʻohana e koho i nā mea kūpono no ka axial split case pump e like me nā pono maoli e hoʻolōʻihi i ke ola lawelawe o ka pamu e like me ka hiki.
