A ʻōnaehana hydraulichoʻohana i ka wai kaomi e hoʻouna i ka mana a hana i ka hana mechanical. Hoʻololi ia i ka ikehu mechanical i ka mana wai, a laila hoʻi i ka neʻe. Ke hilinaʻi nei ka poʻe ʻenekinia i nā loina e like me nā hoʻohālikelike Navier-Stokes a me ka formula Darcy-Weisbach e hoʻonui ai.hoʻolālā ʻōnaehana hydraulic, e like me ka mea i hōʻike ʻia ma kekahi kikoʻīkiʻi ʻōnaehana hydraulic.
Nā mea lawe nui
- Hoʻohana nā ʻōnaehana hydraulic i ka wai kaomi e hoʻonui i ka ikaika a hana i nā hana koʻikoʻi me ka mana pololei, e pili ana i ke kānāwai o Pascal.
- Loaʻa nā ʻāpana koʻikoʻinā pāpaʻi, nā pūnāwai, nā kiwikā, nā mea hana, a me ka wai, kēlā me kēia mea pono no ka hoʻouna ʻana a me ka mana kūpono.
- Hiki i nā ʻōnaehana hydraulic ke hoʻoikaika i nā ʻoihana he nui ma ka hāʻawi ʻana i ka ikaika kiʻekiʻe, ka ikaika o ka ikehu, a me ka hilinaʻi, akā pono lākou i ka mālama mau ʻana e pale aku i nā leaks a me ka haumia.
Pehea ka hana ʻana o kahi ʻōnaehana Hydraulic
Nā Kumu Kumu o ka Pūnaehana Hydraulic (Pascal's Law)
Hoʻohana ʻia kahi ʻōnaehana hydraulic e pili ana i ke kānāwai ʻo Pascal, kahi kumu kumu i ka mechanics fluid. Wahi a Pascal's Law, ke hoʻohana ʻia ke kaomi i kahi wai paʻa, e hoʻoili like ʻia ke kaomi ma nā ʻaoʻao a pau o ka wai. Hāʻawi kēia kumumanaʻo i nā ʻōnaehana hydraulic e hoʻonui i ka ikaika a hana i ka hāpai kaumaha me ka liʻiliʻi o ka hoʻokomo.
No ka laʻana, ke hoʻohana ke kanaka i ka ikaika i kahi piston liʻiliʻi, hele ka kaomi i hana ʻia i loko o ka wai ma o nā paipu a me nā paipu i kahi piston nui aʻe. ʻO ka piston nui aʻe, ʻoi aku ka nui o ka ʻili, hoʻopuka i ka ikaika hoʻopuka. ʻO ka pilina ma waena o ka hoʻokomo a me ka ikaika puka ma muli o ka ratio o nā wahi piston. Inā he 2 kenimika huinaha ka ʻāpana o ka piston hoʻokomo a ʻo ka piston hoʻopuka he 20 mau kenimika square, ʻoi aku ka nui o ka ikaika o ka hoʻopuka ma mua o ka ikaika hoʻokomo, me ka manaʻo e hoʻohana ʻia ke kaomi like.
Hiki i ka Pascal's Law ke hoʻohana i nā paipu a me nā ipu o nā ʻano like ʻole me ka pau ʻole o ke kaomi, e hiki ke hoʻololi ʻia no nā noi mechanical like ʻole.
Hoʻokumu kēia kumumanaʻo i ke kumu no nā mea hana e like me nā kaomi hydraulic, nā kaʻa kaʻa, a me nā mīkini hana. ʻO ka hiki ke hoʻouna i ke kaomi like ʻole e hiki ai i nā ʻenekinia ke hoʻolālā i nā ʻōnaehana hiki ke hāpai i nā kaʻa, hana i nā mea kaumaha, a hāʻawi i ka mana pololei i nā ʻoihana ʻoihana.
ʻO ka hana ʻanuʻu o kahi ʻōnaehana Hydraulic
ʻO ka hana ʻana o kahi ʻōnaehana hydraulic e pili ana i nā ʻanuʻu koʻikoʻi, ʻo kēlā me kēia mea e hāʻawi i ka hoʻololi kūpono a me ka mana o ka mana. Hōʻike ʻia ke kaʻina hana maʻamau:
- Hookomo ikehu: Hoʻomaka ka ʻōnaehana me kahi hoʻokomo mechanical, e like me ke kaʻa uila a i ʻole ka ʻenekini, e hoʻokele apāpaʻa hydraulic.
- Paʻi wai: Hoʻopuka ka paila i ka wai hydraulic mai kahi waihona a hoʻoikaika iā ia, e hana i kahi kahe o ka wai ma lalo o ke kaomi kiʻekiʻe.
- Ka lawe ana i ke kaomi: Holo ka wai kaomi ma o nā paipu a me nā paipu i nā ʻāpana like ʻole, e like me nā valves a me nā mea hana.
- Hoʻomalu a kuhikuhi: Hoʻoponopono nā valves i ke kuhikuhi, kaomi, a me ka holo kahe o ka wai, e ʻae i ka mana pololei ma luna o ka neʻe ʻana o nā mea hana.
- Hoʻopuka mīkini: Nā mea hana, e like me nā cylinders a i ʻolenā motika hydraulic, e hoʻohuli hou i ka mana wai i loko o ka neʻe mechanical, e hana ana i nā hana e like me ka hāpai ʻana, ka pahu ʻana, a i ʻole ka ʻōwili ʻana.
- Kahe Hoʻi: Ma hope o ka pau ʻana o kāna hana, hoʻi ka wai i ka waihona, mākaukau e hoʻihoʻi ʻia e ka pamu.
Hoʻohana pinepine ka poʻe ʻenehana i nā mea hana diagnostic, me nā ana kaomi a me nā multimeter digital, e nānā i nā ʻōnaehana ʻōnaehana e like me nā pae kaomi a me nā ʻano uila. Inā hōʻike nā ana i nā hewa, hiki iā lākou ke nānā i nā ʻāpana o loko no ka ʻaʻahu a i ʻole ka pōʻino. Hoʻohui kēia ala i ka ʻikepili quantitative me ka nānā ʻike maka e hōʻoia i ka hana ʻana o ka ʻōnaehana.
Ua hōʻike nā haʻawina hoʻokolohua e hiki i nā ʻōnaehana hydraulic ke hoʻokō i ka mālama ʻana i ka ikehu nui a me ka hoʻomaikaʻi maikaʻi ʻana me nā ʻenehana hoʻokele holomua. No ka laʻana, hiki i nā kaʻapuni e hoʻohana ana i nā kīwaha kahe kahe ke hōʻemi i ka hoʻohana ʻana i ka ikehu ma o 15% me ka haʻahaʻa ʻole a kokoke i 10% i nā ukana kiʻekiʻe. Hōʻike pū nā ana wela e hana ana nā ʻōnaehana maikaʻi i nā mahana haʻahaʻa, e hoʻonui ai i ka hoʻomau a hoʻemi i ka ʻaʻahu.
ʻO nā kūlana o ka ʻoihana, e like me ISO 4409: 2007, e hāʻawi i nā alakaʻi no ka hoʻāʻo ʻana a me ka hōʻoia ʻana i ka pono o nā paila hydraulic a me nā kaʻa. Hōʻoia kēia mau kūlana i hiki i nā mea hana a me nā ʻenekini ke hilinaʻi i ka ʻikepili pololei, hiki ke hoʻihoʻi hou i ke koho ʻana a mālama i nā ʻāpana ʻōnaehana.
'Ōlelo Aʻo: ʻO ka hoʻomaopopo ʻana i ka hana ʻanuʻu a me nā kumu kumu o kahi ʻōnaehana hydraulic e kōkua i nā mea ʻenekinia e hoʻolālā i nā mīkini hilinaʻi a maikaʻi hoʻi no ka nui o nā noi.
