ʻO nā ʻāpana metala a me ka wai mai ka makuahine

Slurry cavitation mechanical

ʻO ke ʻano kikoʻī o nā lau a me ke kahe wikiwiki ʻana o ka hoʻololi koke ʻana i nā hiʻohiʻona kahe o ka wai i loko o ka impeller kahe o ka Slurry, e hana ana i ka hāʻawi ʻana i ke kaomi wai i ka lau.

ʻAʻole hana ka lau ma luna o ka wai ma mua, aia kahi wahi haʻahaʻa haʻahaʻa ma ka ʻāina.Ke emi iho ke kaomi haahaa o ke kahe kahe o ka wai a hiki i ka wela o ka mahu o ka wai, e mahuka ka wai a lilo i mau ohu e hoomaka malie;ʻohu me ka wai e kahe ana ma ke ala kahe i kēlā manawa a ʻoi aku ke kiʻekiʻe o ke kaomi transient hiolo.ʻO ka manawa i hāhā ai ka ʻōhū, ʻo ka wai e hoʻopuni ana i ka ʻōpū i hoʻokumu ʻia i ka wā o ka wikiwiki o ka komo ʻana o nā lua, a hele pū ʻia me ke kiʻekiʻe kiʻekiʻe o ka localized, high pressure water hammer phenomenon, ʻo ia ke ʻano o ka cavitation.Wahi a nā haole naʻauao hoʻokolohua haʻawina i hōʻike ʻia ka hāmare wai cavitation nā hiʻohiʻona nui o ke kaomi ʻāpana a hiki i 30MPa ( manometry wahi o 1.5mm2).Ua ana ʻia ka cavitation i ka wā o ka hāmare wai wai pinepine o 25,000 mau manawa / kekona, ka ʻili metala ma lalo o ka hāmare wai no ka hahau pinepine ʻana e ka pōʻino luhi.

A, i loko o ka hoʻomau ʻana o ka hawewe puʻupuʻu cyclical, kahe koke ka wai i loko a i waho o nā pores o ka metala, ka ʻili metala o kahi concavity, nā ʻāpana metala a me ka wai mai ka makuahine, e hopena i ka lua nui.ʻO nā ʻāpana nui o ka pāpaʻi i loko o ia ʻano manawa, e hoʻomake ka puʻu i ka walaʻau a me ka haʻalulu, i mea e hōʻeha nui ai ka pump cavitation, ʻo ia hoʻi ma nā ʻano aʻe: Ka hana o ka nosedive pump.

I kēia manawa ka pihi HQ, ka pihi NQ i lalo i ke ʻano hikiwawe loa,mea hana pahū slurryʻAʻole e hana ka pauma koʻikoʻi, ke kahe ʻana o ka paila, ma muli o ka pump cavitation, ka impeller a me ka hoʻololi ʻana o ka ikehu ma waena o ka wai kahe a me ka hoʻopili ʻana, ʻaʻole i hoʻopaʻa ʻia ke kahawai wai ʻaʻole wale e ka ʻōhū, a piʻi aʻe ke kahe.Kiʻi 2: Hoʻopuka ka slurry pump i ka haʻalulu a me ka walaʻau.Hana ʻia ka Cavitation ke kiʻekiʻe ke kaomi me ka hāʻule ʻana o nā ʻōpū i ka hana mau ʻana i kahi haʻalulu hydraulic ikaika, e hana ana i ka haʻalulu a me ka walaʻau.

Slurry pump mechanical surface flow parts from mechanical damage, the surface of the impeller honeycomb or spongy.Inā ʻino nā kinoea i hoʻokuʻu ʻia i ka wā e hoʻoheheʻe ʻia ai ka wai, e hoʻopuka ana i kahi luku kemika (ʻo ka luku ʻana o ka mea mua ka mea nui).
