E like me ke kani ʻana i ka hopena maikaʻi ʻole i ke kino o ke kanaka, hiki i kekahi mau alapine ke pāʻani i ka pōʻino i nā mea hana ʻoihana ke koho pono ʻia ka valve control, aia ka piʻi nui o ka cavitation, kahi e alakaʻi ai i nā pae kiʻekiʻe a me nā haʻalulu, e hopena i ka pōʻino wikiwiki i nā paipu o loko a me lalo o kakiwikā.
Eia kekahi, hoʻoulu pinepine ka leo kiʻekiʻe i ka haʻalulu i hiki ke hōʻino i nā paipu, nā mea kani a me nā mea hana ʻē aʻeValveme ka hele ʻana o ka manawa, ka hoʻohaʻahaʻa ʻana o nā ʻāpana, ka cavitation valve i hoʻokumu ʻia e ka pipeline system prone i ka pōʻino nui. ʻO kēia pōʻino ke kumu nui ʻia e ka ikehu leo haʻalulu, ke kaʻina hana corrosion wikiwiki a me ka cavitation i hōʻike ʻia e ke kiʻekiʻe o ka walaʻau nui o ka haʻalulu amplitude nui i hana ʻia e ka hoʻokumu ʻana a me ka hāʻule ʻana o nā ʻōpala mahu kokoke a i lalo o ke kahawai..
ʻOiai maʻa mau kēia i ka pōlelekiwikāa me nā puʻupuʻu rotary i loko o ke kino, hiki ke loaʻa i kahi pōkole a kiʻekiʻe e like me ka ʻāpana kino wafer o ka V-ballkiwikā, ʻoi akukiwi lelema ka ʻaoʻao o lalo o ka valve kekiwikāua hoʻokūpaʻa ʻia i hoʻokahi kūlana prone i ka cavitation phenomena, kahi hiki ke leakage i ka paipa valve a me ka hoʻoponopono ʻana, ʻaʻole kūpono ka valve no kēia ʻāpana o ka laina.
ʻAʻole paha e hiki mai ka cavitation i loko o ka valve a i lalo paha o ka valve, e hoʻopōʻino nui ʻia nā mea hana ma ka wahi cavitation i nā kiʻiʻoniʻoni ultra-thin, nā pūnāwai a me nā hale cantilever ʻāpana liʻiliʻi, hiki i nā haʻalulu amplitude nui ke hoʻoulu i nā oscillations. Loaʻa nā helu hāʻule pinepine i nā mea hana e like me nā ana kaomi, nā mea hoʻouna, nā lima thermocouple, nā kahe wai, nā ʻōnaehana sampling Actuators, positioners a me nā hoʻololi palena e loaʻa ana nā punawai e ʻeha i ka ʻaʻahu wikiwiki, a me nā pale kau, nā mea hoʻopili a me nā mea hoʻohui e wehe a hāʻule ma muli o ka haʻalulu.
He mea maʻamau ka ʻino ʻino, ka mea i loaʻa ma waena o nā ʻili ʻeleʻele i ʻike ʻia i ka haʻalulu, ma kahi kokoke i nā pahu cavitation. Hoʻopuka kēia i nā oxides paʻakikī ma ke ʻano he abrasives e hoʻolalelale i ka ʻaʻahu ma waena o nā ʻili i hoʻohana ʻia. ʻO nā mea i hoʻopilikia ʻia e pili ana i ka hoʻokaʻawale ʻana a me ka nānā ʻana i nā valves, me ka hoʻohui ʻana i nā valves control, pumps, rotating screens, samplers a me nā ʻano hana ʻē aʻe.
Hiki i nā haʻalulu kiʻekiʻe ke pohā a hoʻopau i nā ʻāpana valve metala a me nā paia paipu. Hiki ke hoʻohaumia i nā ʻāpana metala a i ʻole nā mea kemika corrosive i ka media i loko o ka pipeline, hiki ke loaʻa i kahi hopena koʻikoʻi i ka paipu kīpē maʻemaʻe a me ka maʻemaʻe kiʻekiʻe. ʻAʻole ʻae ʻia kēia.
ʻOi aku ka paʻakikī o ka wānana o ka hāʻule ʻana o ka cavitation o nā puʻupuʻu plug a ʻaʻole i helu wale ʻia ka hāʻule ʻana o ke kaomi choke. Hōʻike ka ʻike e hiki ke hāʻule ke kaomi i ke kahawai nui i ke kaomi mahu o ka wai ma mua o ka vaporization kūloko o ka wahi a me ka hāʻule ʻana o ka pahu mahu. ʻO kekahi mau mea hana valve e wānana i ka hāʻule ʻole ʻana o ka eclipse mua ma ka wehewehe ʻana i ka hāʻule ʻana o ke kaomi pōʻino mua. ʻO ke ʻano o ka mea hana valve no ka hoʻomaka ʻana me ka wānana ʻana i ka pōʻino o ka cavitation ma muli o ka hāʻule ʻana o nā ʻōmole mahu, e hoʻoulu ai i ka cavitation a me ka walaʻau. Ua hoʻoholo ʻia e pale ʻia ka pōʻino cavitation nui inā ʻoi aku ka pae o ka walaʻau i helu ʻia ma lalo o nā palena i helu ʻia ma lalo nei.
ʻO ka nui o ka valve a hiki i 3 iniha - 80 dB
ʻO ka nui o ka valve o 4-6 iniha - 85 dB
ʻO ka nui o ka valve 8-14 iniha - 90 dB
ʻO ka nui o ka valve he 16 iniha a ʻoi aku ka nui - 95 dB
Nā ʻano no ka hoʻopau ʻana i ka pōʻino cavitation
ʻO ka hoʻolālā valve kūikawā no ka hoʻopau ʻana i ka cavitation e hoʻohana i ka kahe ʻoki a me ka hāʻule kaomi ʻana i ka graded:
ʻO ka "Valve diversion" ka mahele ʻana i kahi kahe nui i loko o nā kahe liʻiliʻi, a ua hoʻolālā ʻia ke ala kahe o ka pahu i hiki ai ke kahe ʻana ma o nā puka liʻiliʻi like. No ka mea, ua helu ʻia ka ʻāpana o ka nui o ka puʻupuʻu cavitation ma o ka puka e hele ai ke kahe. ʻO ka puka liʻiliʻi e hiki ai i nā ʻōhū liʻiliʻi, e hoʻemi ana i ka walaʻau a me ka liʻiliʻi o ka pōʻino i ka wā e pōʻino ai.
ʻO ka "paʻi paʻi paʻi helu" ʻo ia ka mea i hoʻolālā ʻia ka valve e loaʻa i ʻelua a ʻoi aʻe paha nā kiko hoʻoponopono i ka moʻo, no laila ma kahi o ka hāʻule ʻana o ke kaomi holoʻokoʻa i hoʻokahi ʻanuʻu, e lawe i kekahi mau ʻanuʻu liʻiliʻi. ʻOi aku ka liʻiliʻi ma mua o ka hāʻule ʻana o kēlā me kēia kaomi hiki ke pale i ke kaomi i ka shrinkage mai ka hāʻule ʻana o ke kaomi mahu o ka wai, pēlā e hoʻopau ai i ke ʻano o ka cavitation i ka valve.
ʻO ka hui pū ʻana o ka hoʻohuli ʻana a me ka hoʻohaʻahaʻa ʻana i ke kaomi i loko o ka pahu hoʻokahi e hiki ai ke hoʻomaikaʻi i ka pale cavitation e. I ka hoʻololi ʻana o ka valve, ʻoi aku ka kiʻekiʻe o ka hoʻonohonoho ʻana i ka valve mana a me ke kaomi ma ka puka komo o ka valve (e laʻa i ka ʻaoʻao i uka, a i ʻole ma kahi kiʻekiʻe haʻahaʻa), i kekahi manawa e hoʻopau i nā pilikia cavitation.
Eia kekahi, ke hoʻonoho ʻana i ka valve control ma kahi o ka wela wai, a no laila ke kaomi ʻana o ka mahu (e like me ka mea hoʻololi wela ʻaoʻao haʻahaʻa) hiki ke kōkua i ka hoʻopau ʻana i nā pilikia cavitation.
Ua hōʻike ʻia ka hōʻuluʻulu manaʻo ʻaʻole pili wale ka cavitation o nā valves i ka hana hoʻohaʻahaʻa a me ka pōʻino i nā kiwi. Pilikia hoʻi nā paipu lalo a me nā mea hana. ʻO ka wānana ʻana i ka cavitation a me ka hana ʻana i nā hana e hoʻopau ai ʻo ia wale nō ke ala e pale aku ai i ka pilikia o ka hoʻohana ʻana i ka valve pipiʻi.
