Pehea e pale ai i ka cavitation ma ka ʻōnaehana hydraulic?

I loko o ka ʻōnaehana hydraulic, ʻo ka cavitation kahi mea e hoʻololi wikiwiki ai i ke kaomi i ka ʻaila e hoʻokumu ʻia ai nā lua liʻiliʻi i piha i ka mahu ma nā wahi i haʻahaʻa haʻahaʻa.I ka manawa e emi iho ai ke kaomi ma lalo o ke kiʻekiʻe o ka mahu-huhū ma ka mahana hana ʻaila, e hana koke ʻia kekahi mau lua i piha i ka mahu.ʻO ka hopena, ʻo ka nui o nā ʻōpū ea e alakaʻi i ka hoʻopau ʻana o ka aila i loko o ka paipu a i ʻole nā ​​​​mea hydraulic.

ʻO ke ʻano o ka cavitation ka mea maʻamau i ka puka a me ka puka o ka valve a me ka pamu.Ke kahe ka aila ma ke ala ʻokiʻoki o ka valve, piʻi ka wikiwiki o ka wai a emi ke kaomi ʻaila, a laila hiki mai ka cavitation.Eia kekahi, ʻike ʻia kēia ʻano i ka wā i hoʻokomo ʻia ai ka pauma ma kahi kūlana kiʻekiʻe, ʻoi aku ka nui o ka pale ʻana o ka ʻaila no ka mea liʻiliʻi loa ke anawaena o loko o ka paipu suction, a i ʻole ka lawa ʻole o ka ʻaila no ka wikiwiki o ka pauma.

ʻO nā ʻōhū ea, e neʻe ana ma waena o ke kaomi kiʻekiʻe me ka aila, e haki koke ma muli o ka hoʻoikaika ʻana o ke kaomi kiʻekiʻe, a laila e hoʻopuni ana nā ʻāpana wai e hoʻopiʻi i nā ʻōhū i ka wikiwiki kiʻekiʻe, a no laila ke kiʻekiʻe-wikiwiki collision ma waena o kēia mau particles hua hydraulic hapa.ʻO ka hopena, piʻi nui ke kaomi a me ka mahana ma kekahi hapa, e ʻike ʻia ka haʻalulu a me ka walaʻau.

Ma ka pā mānoanoa a puni kahi e hoʻokuʻu ai nā lua a me ka ʻili o nā mea, hāʻule nā ​​​​mea metala superficial, ma muli o ka ʻeha lōʻihi o ka hopena hydraulic a me ke kiʻekiʻe o ka wela, a me ka hoʻoikaika kino loa i hana ʻia e ke kinoea mai ka aila.

Ma hope o ka hōʻike ʻana i ke ʻano o ka cavitation a me kāna hopena maikaʻi ʻole, hauʻoli mākou e kaʻana like i ko mākou ʻike a me kā mākou ʻike pehea e pale ai i ka hana ʻana.

【1】 E ho'ēmi i ka hāʻule puʻe ma kahi e kahe ana ma nā puka liʻiliʻi a me nā kikowaena: ʻo ka manaʻo o ke kaomi ʻana o ka kahe ʻana ma mua a ma hope o nā puka a me nā kikowaena he p1/p2 <3.50.
【2】E wehewehe pono i ke anawaena o ka paipu absorption pump hydraulic, a kaohi i ka holo o ka wai i loko o ka paipu ma nā ʻano he nui;e ho'ēmi i ke kiʻekiʻe o ka hoʻomoʻa ʻana o ka paila, a e hoʻemi i ka pōʻino o ke kaomi i ka laina inlet e like me ka hiki.
【3】E koho i ka hui ʻana o ka ea kiʻekiʻe a hoʻohana i ka pauma wai kaomi kiʻekiʻe ma ke ʻano he pauma kōkua e hoʻolako i ka aila.
【4】E hoʻāʻo e hoʻohana i nā paipu pololei a pau i loko o ka ʻōnaehana, e pale i ka huli ʻoi a me ka ʻāpana haiki.
【5】E hoʻomaikaʻi i ka mea hiki ke pale aku i ka etching kinoea.
