Slurry cavitation diagnostic - Noise Law
ʻAʻole hiki ke hoʻohana maʻamau i ka hoʻohana ʻana o ka mea hoʻohana i nā ʻano diagnostic slurry pump cavitation no ka hoʻoholo ʻana i ke ʻano o ke ʻano cavitation. Inā paha i loko o ka lawelawe ʻana i ka pump cavitation, cavitation pōʻino i ka hoʻohui ʻana i ke ʻano o ka nānā ʻana, hiki iā ʻoe ke hoʻohana i ke ʻano ultrasonic, ka walaʻau ʻana o ka pump in vitro method, vibration a me nā ʻano hana ʻē aʻe.
1 Ke ala nānā ʻO kēia ʻano, i ka nānā ʻana, e like me ka luku ʻana i ke ʻano o ka ʻili e hoʻokolokolo ʻia. No ka mea, ʻo ka cavitation, ka hoʻolei ʻana i ka porosity, ka ʻaʻahu erosion, ka corrosion a me nā mea ʻē aʻe e ʻokoʻa ke ʻano o ka ʻili metala mai ke ʻano kūpono. Hōʻike pinepine ʻia ka hōʻino cavitation o ka ʻili metala i kahi honeycomb, ka mea i hahau ʻia e ka wikiwiki o ka wai e waiho ana i ka ʻili metala o ka luhi metala, no laila e kamaʻilio maʻamau ka honeycomb me waho, ʻo ka hapa nui o nā metala perpendicular i nā lua ili. Hoʻolei defects ua pinepine loose hohonu i loko o ka metala, a i kekahi manawa ka wai erosion o ka metala i loko o ka loose, hōʻike i ka ili pores a me ka hemahema wawae cavitation, akā, e hoʻomau i ka wehe 'ana ma ka mechanical hana e loaa kona loko ili he pores.
2 He ʻauwaha hoʻokahi me ka ʻaoʻao o ke kahe ʻana, akā e nānā pono inā he vortex wai. He mea maʻalahi kēia ʻano a ʻaʻole hiki ke hoʻopili me ka pamu. Eia naʻe, ma muli o ke kānāwai walaʻau ma ka pule Quarters ʻoi aku ka hopena o ka walaʻau kaiapuni, i ka wā e hōʻike ai i kona ikaika kiʻekiʻe. Ua hiki aku ka pahu pahu maʻamau i kahi manawa ikaika loa, kahi i hele ai ka pepeiao ma o ka cavitation cavitation popping i nā kūlana hoʻoholo maikaʻi. No laila, ʻaʻole kūpono ke ʻano o ke kani ʻana o ka pauma no ka nānā ʻana ma ka pūnaewele i ka hanana ʻana o ka cavitation.
3 Ma ke ala vibration accelerometer vibration frequency pump probe method, maʻalahi ke ʻano, akā haʻahaʻa haʻahaʻa. ʻOi loa no nā pamu nui e ʻoʻoleʻa. Kaiapuni i loko o ka pump cavitation bubbles debacle ma muli o ka excitation e ala mai unresponsive, oiai ka nui o ka pump vibration kumu. No ka mea, ua uhi pinepine ʻia ka haʻalulu i hana ʻia e ka cavitation i waena o nā haʻalulu ʻē aʻe. No laila, kūpono wale ke ʻano vibration no ka hoʻopili ʻana i ka cavitation nānā ma ka pūnaewele.
4 Ultrasonic cavitation ultrasonic ana kaʻina hana mea maʻalahi , a 'aʻole i lalo i ka 'ē aʻe kaiapuni leo interference, cavitation hanana a me ka ulu o ka ikaika sensitivity. No laila, ma ke ʻano he pumping station ma ka pūnaewele nānā ʻana i ka cavitation kahi ala kūpono.
