E like me ke kani ʻana o ke kani i ka hopena maikaʻi ʻole i ke kino o ke kanaka, hiki i kekahi mau alapine (frequencies) ke hoʻopilikia i nā lako hana ʻoihana ke koho pono ʻia ka valve mana, aia kahi pilikia nui o ka cavitation, kahi e alakaʻi ai i nā pae walaʻau kiʻekiʻe a me ka haʻalulu, e hopena ana i ka hōʻino wikiwiki loa i nā paipu kūloko a me lalo o kakiwikā.

Eia kekahi, ʻo nā pae walaʻau kiʻekiʻe e hoʻoulu pinepine i ka haʻalulu e hōʻino paha i nā paipu, nā mea kani a me nā lako ʻē aʻeKiwikāme ka hala ʻana o ka manawa, ka hōʻino ʻana o nā ʻāpana, ka cavitation valve i hoʻokumu ʻia e ka ʻōnaehana pipeline i hiki ke hōʻino nui ʻia. ʻO kēia pōʻino ka mea nui i hoʻokumu ʻia e ka ikehu walaʻau haʻalulu, ke kaʻina hana palaho wikiwiki a me ka cavitation i hōʻike ʻia e ka pae walaʻau kiʻekiʻe o ka haʻalulu amplitude nui i hoʻokumu ʻia e ka hoʻokumu ʻana a me ka hiolo ʻana o nā pehu mahu kokoke a ma lalo o ka shrinkage..

ʻOiai ke hana pinepine ʻia kēia ma ka pōpōnā kiwikāa me nā valves rotary i loko o ke kino, hiki iā ia ke hana maoli i kahi hoʻōla pōkole a kiʻekiʻe e like me ka ʻāpana kino wafer o ka V-ballkiwikā, ʻoi aku hoʻinā kiwikā pepekema ka ʻaoʻao iho o ka valve i ka wā ekiwikāua hoʻokaumaha ʻia ma kekahi kūlana i hiki ke loaʻa i ka hanana cavitation, kahi mea i hiki ke loaʻa i ka leakage i loko o ka paipu valve a me ka hoʻoponopono ʻana i ka welding, ʻaʻole kūpono ka valve no kēia ʻāpana o ka laina.

Me ka nānā ʻole inā hana ʻia ka cavitation i loko o ka valve a i ʻole ma lalo o ka valve, e hōʻino nui ʻia nā lako ma kahi cavitation i nā kiʻiʻoniʻoni lahilahi loa, nā pūnāwai a me nā ʻāpana cantilever liʻiliʻi, hiki i nā haʻalulu amplitude nui ke hoʻoulu i nā oscillations. Loaʻa nā wahi hāʻule pinepine i nā mea hana e like me nā anakahi kaomi, nā mea hoʻoili, nā lima thermocouple, nā mika kahe, nā ʻōnaehana laʻana. E ʻeha nā actuators, nā positioners a me nā kuapo palena i loaʻa nā pūnāwai i ka ʻaʻahu wikiwiki ʻia, a e wehe a hāʻule nā ​​brackets kau, nā mea paʻa a me nā mea hoʻohui ma muli o ka haʻalulu.

ʻO ka palaho fretting, kahi e kū mai ana ma waena o nā ʻili i hoʻohana ʻia i hōʻike ʻia i ka haʻalulu, he mea maʻamau ia ma kahi kokoke i nā valves cavitation. Hoʻopuka kēia i nā oxides paʻakikī e like me nā mea abrasives e hoʻolalelale i ka ʻaʻahu ʻana ma waena o nā ʻili i hoʻohana ʻia. ʻO nā lako i hoʻopilikia ʻia e pili ana i nā valves hoʻokaʻawale a me nā check, me nā valves hoʻomalu, nā pamu, nā pale wili, nā samplers a me kekahi ʻano wili a paheʻe paha.

Hiki i nā haʻalulu amplitude kiʻekiʻe ke haki a hōʻino i nā ʻāpana valve metala a me nā paia paipu. Hiki i nā ʻāpana metala i hoʻopuehu ʻia a i ʻole nā ​​​​mea kemika ʻino ke hoʻohaumia i ka media i loko o ka pipeline, hiki ke loaʻa ka hopena koʻikoʻi i nā paipu valve maʻemaʻe a me nā media paipu maʻemaʻe kiʻekiʻe. ʻAʻole ʻae ʻia kēia.

ʻOi aku ka paʻakikī o ka wānana ʻana i ka hāʻule ʻana o ka cavitation o nā valves plug a ʻaʻole ia he helu wale ʻia ʻana o ka hāʻule ʻana o ke kaomi choke. Hōʻike ka ʻike he hiki ke hāʻule ke kaomi i loko o ke kahawai nui i ke kaomi mahu o ka wai ma mua o ka vaporization kūloko o ka wahi a me ka hiolo ʻana o ka pehu mahu. Wānana kekahi mau mea hana valve i ka hāʻule ʻana o ka eclipse mua ma ka wehewehe ʻana i ka hāʻule mua o ke kaomi. ʻO ke ʻano hana a ka mea hana valve e hoʻomaka ai me ka wānana ʻana i ka hōʻino cavitation e pili ana i ka hiolo ʻana o nā pehu mahu, e hana ana i ka cavitation a me ka walaʻau. Ua hoʻoholo ʻia e pale ʻia ka hōʻino cavitation koʻikoʻi inā ʻoi aku ka pae walaʻau i helu ʻia ma lalo o nā palena i helu ʻia ma lalo nei.

Ka nui o ka valve a hiki i 3 ʻīniha - 80 dB

Ka nui o ka valve o 4-6 ʻīniha - 85 dB

Ka nui o ka valve 8-14 ʻīniha - 90 dB

Nā nui o nā kiwikā he 16 ʻīniha a ʻoi aku - 95 dB

Nā ʻano hana no ka hoʻopau ʻana i ka pōʻino cavitation

Hoʻohana ka hoʻolālā valve kūikawā e hoʻopau i ka cavitation i ke kahe māhele a me ka hāʻule ʻana o ke kaomi i hoʻopaʻa ʻia:
ʻO ke "hoʻololi ʻana o ka valve" ʻo ia ka hoʻokaʻawale ʻana i kahi kahe nui i kekahi mau kahe liʻiliʻi, a ua hoʻolālā ʻia ke ala kahe o ka valve i hiki ai ke kahe ma o kekahi mau puka liʻiliʻi like. ʻOiai ua helu ʻia ka hapa o ka nui o ka pehu cavitation ma o ka puka e hele ai ke kahe. ʻO ka puka liʻiliʻi e hiki ai i nā pehu liʻiliʻi, e hopena ana i ka walaʻau liʻiliʻi a me ka pōʻino liʻiliʻi i ka wā e hiki mai ai ka pōʻino.

ʻO ke ʻano o ka "hāʻule kaomi papa" ua hoʻolālā ʻia ka valve e loaʻa i ʻelua a ʻoi aku paha nā kiko hoʻoponopono ma ke ʻano moʻo, no laila ma kahi o ka hāʻule kaomi holoʻokoʻa i hoʻokahi ʻanuʻu, lawe ia i kekahi mau ʻanuʻu liʻiliʻi. ʻO ka emi ʻana ma mua o ka hāʻule kaomi pākahi hiki ke pale i ke kaomi i loko o ka shrinkage mai ka hāʻule ʻana o ke kaomi mahu o ka wai, a laila e hoʻopau ana i ka hanana o ka cavitation i loko o ka valve.

ʻO ka hui pū ʻana o ka hoʻohuli ʻana a me ka hoʻonohonoho ʻana o ke kaomi i loko o ka valve like e ʻae ai i ka hoʻomaikaʻi ʻana i ke kūʻē ʻana o ka cavitation. I ka wā o ka hoʻololi ʻana o ka valve, ʻoi aku ke kiʻekiʻe o ke kau ʻana i ka valve kaohi a me ke kaomi ma ke komo ʻana o ka valve (e laʻa me ka ʻaoʻao ma luna, a i ʻole ma kahi kiʻekiʻe haʻahaʻa), i kekahi manawa e hoʻopau ana i nā pilikia cavitation.

Eia kekahi, ʻo ke kau ʻana i ka valve hoʻomalu ma kahi o ka mahana wai, a no laila ke kaomi mahu haʻahaʻa (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 wale ka hanana cavitation o nā valves e pili ana i ka hana hōʻino a me ka hōʻino ʻana i nā valves. Aia pū kekahi mau paipu a me nā lako i lalo i ka pilikia. ʻO ka wānana ʻana i ka cavitation a me ka lawe ʻana i nā hana e hoʻopau ai iā ia ke ala wale nō e pale aku ai i ka pilikia o nā lilo hoʻohana valve pipiʻi.
