He aha nā ʻāpana nui ʻelima o ka mīkini hydraulic?

Pūnaehana hydraulicHoʻohana ʻia ma ke kānāwai o Pascal, me ka hoʻohana ʻana i ka wai hydraulic ma ke ʻano he mea hana e hoʻouna i ke kaomi a me ka mana ma o nā hoʻololi leo i hoʻopaʻa ʻia, a laila e loaʻa ai ka hoʻololi ʻana a me ka hoʻoili ʻana. ʻO ka paila hydraulic ke kumu mana, hoʻololi i ka ikehu mechanical i ka ikehu hydraulic. Ma ka hoʻomalu ʻana i nā mea e like me nā kiwi hoʻokele kuhikuhi, nā ʻāpana hoʻokele kaomi, a me nā ʻāpana hoʻokele kahe, hoʻoponopono ka ʻōnaehana i ke ala kahe, kaomi, a me ka kahe kahe o ka wai hydraulic e hoʻomalu i ka neʻe ʻana o nā mea hana (e laʻa,nā pahu hydraulic). Holo ka wai hydraulic i loko o ka ʻōnaehana, ʻaʻole wale i ka hoʻouna ʻana i ka ikehu akā hāʻawi pū kekahi i ka lubrication, ka hoʻoluʻu, a me ka pale ʻana o ka ʻōnaehana. Ma muli o ko lākou mau pono koʻikoʻi e pili ana i ka nui o ka mana kiʻekiʻe, ka hoʻouna maʻalahi, ka pane wikiwiki, a me ka maʻalahi o ka pale ʻana i ka overload, ua hoʻohana nui ʻia nā ʻōnaehana hoʻoili hydraulic i nā kula e like me nā mīkini hana, aerospace, a me ka hana akamai. Ke hilinaʻi nei ka hana maikaʻi o ka ʻōnaehana i ka hana hoʻonohonoho ʻana o ʻelima mau mea nui: ka hoʻololi ʻana i ka ikehu, ka mana mana, ka mana pololei, ke kākoʻo kōkua, a me ka hoʻouna ʻana. Hoʻohui pū ʻia, hoʻokumu lākou i ka ʻōnaehana loop -paʻa piha e hoʻopuni ana i "ka mana, ka hana, ka hoʻoponopono, ke kākoʻo, a me ka mea lawe."

ʻO kēia ka ʻikepili ʻōnaehana o nā ʻāpana ʻelima o ka mīkini hydraulic mai nā ʻāpana ʻehā o nā hana koʻikoʻi, nā ʻano maʻamau, nā ʻano hoʻohālikelike a me nā hiʻohiʻona noi.

Papa 1: Hoʻohālikelike i nā ʻāpana koʻikoʻi o ʻelima mau mea mīkini hydraulic

ʻO ka hui ʻana o nā ʻāpana ʻelima ke kumu o ka hana kūpono o ka ʻōnaehana hydraulic:

Hoʻohālikelike i ka ikehu ma waena o ka mana a me nā mea hana: Hoʻoponopono ʻia ka ʻaila kaomi mai ka mea mana (e laʻa, plunger pump) e ka mea hoʻomalu (e laʻa, ka valve kahe) a laila komo i ka mea hana (e laʻa, hydraulic cylinder). Hoʻoholo ʻia ka mana hoʻopuka e ka huahana o ke kaomi a me ke kahe kahe. Pono e hoʻohālikelike ʻia nā ʻāpana o ka pauma a me ka mea hana e like me nā hiʻohiʻona ukana (e laʻa, ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ka wikiwiki kiʻekiʻe o ka ukana māmā).

Ka mana pololei o nā ʻāpana hana: Hoʻopololei nā kiwi kuhikuhi i ke kahe wai e hiki ai i ka neʻe ʻana o nā ʻaoʻao ʻelua (e laʻa, ka hoʻonui ʻana o ka cylinder hydraulic / hoʻihoʻi ʻana), kaohi ʻia nā kiwi puʻupuʻu i ke kaomi ʻōnaehana e pale i ka hoʻonui ʻana, a me nā kiwi kahe e hoʻoponopono i ka wikiwiki. Hana pū kēia mau ʻāpana ʻekolu no ka loaʻa ʻana o -loop mana paʻa o ka ikaika, ka wikiwiki, a me ke kūlana (e laʻa, CNC hydraulic press positioning correcting of ±0.1mm).

Hāʻawi nā ʻāpana kōkua i nā pale pono: Mālama ka kānana i ka hoʻomaʻemaʻe ʻaila ma lalo o ka papa NAS 8 (ka nui o ka ʻāpana.<10μm) to prevent valve core jamming; the accumulator absorbs hydraulic shocks (such as pressure fluctuations during sudden shutdowns) to extend system lifespan; the oil tank's heat dissipation design keeps oil temperature within 30-55°C to prevent oxidation and degradation.

The hydraulic fluid's properties-viscosity (VI> 140 at 40°C), wear resistance (PB>1000N i ʻehā- hoʻāʻo pōleʻa), a me ka pale ʻana i ka oxidation-pili pololei i ka pono ʻōnaehana. No ka la'ana, koi 'ia ka aila viscosity ha'aha'a (e la'a, ISO VG 32) i loko o nā kaiapuni anu no ka ho'ēmi 'ana i ke kahe o ke kahe, a'o nā 'ōnaehana pi'i ki'eki'e e pono ke komo-wai hydraulic kū'ē i mea e pale aku ai i ka pahū a me ke ka'a.

Ke koho ʻana i nā mea mana: E koho i ke ʻano o ka pamu e like me ke kaomi hana ʻana o ka ʻōnaehana (ke kaomi haʻahaʻa<7MPa, medium pressure 7~31.5MPa, high pressure>31.5MPa). No ka laʻana, hoʻohana maʻamau ʻia ka pauma gear (kūʻai haʻahaʻa) i nā mīkini mahiʻai, ʻoiai ʻo ka plunger pump (ke kūpaʻa kiʻekiʻe kiʻekiʻe) koi ʻia i nā mīkini mining.

Mea Hoʻohālikelike: ʻO ka pahu hydraulic cylinder (F=P×A, kahi P ke kaomi a ʻo A ka piston area) pono e ʻoi aku ma mua o ka ikaika o ka ukana e hōʻoia i ka hana pono o ka ʻōnaehana hydraulic. Pēlā nō, pono e hoʻokō ka torque o ke kaʻa hydraulic (T=ΔP×V/2π, kahi o ΔP ka ʻokoʻa puʻe a me ka hoʻoneʻe ʻana o V) pono e hoʻokō i nā koi torque ukana e hōʻoiaʻiʻo i ka hana ʻana o ka ʻōnaehana kūpono.

Nā ʻāpana hoʻomalu naʻauao: Ma ka hoʻololi ʻana i nā kiwi hoʻomalu maʻamau me nā kiwi like ʻole a i ʻole servo a me ka hoʻohui ʻana i nā mea ʻike (nā puʻe / neʻe hoʻoneʻe) me nā ʻōnaehana hoʻomalu PLC, loaʻa kēia hopena i ka mana kiʻekiʻe -me nā manawa pane ikaika ma lalo o 50ms, e like me nā servos hydraulic aviation.

ʻO ka mālama ʻana i nā mea kōkua: hoʻololi pinepine i ka kānana (manaʻo ʻia i kēlā me kēia 500 mau hola), e nānā i ke kaomi precharge accumulator (ʻo ke kaomi nitrogen he 60% ~ 70% o ka neʻe ʻana o ka ʻōnaehana), hiki ke hoʻemi i ka helu hemahema o ka ʻōnaehana ma mua o 50%.

Ka hoʻokele wai hana: E nānā mau i ka ʻaila viscosity, moisture content (<0.1%) and contamination to avoid pump wear or valve sticking due to oil deterioration.

Ma waena o nā ʻāpana nui ʻelima o ka mīkini hydraulic, ʻo ka mana o ka mana he "kumu ikehu", ke hana nei ka mea hoʻokele ma ke ʻano he "motion carrier", ʻo ka mea hoʻokele e hana ma ke ʻano he "intelligent hub", hāʻawi ka ʻāpana kōkua i ka "logistical support", a ʻo ka wai hana e hana ma ke ʻano he "energy medium". ʻAʻole hoʻokaʻawale ʻia kēia mau ʻāpana akā hoʻopili ʻia ma o nā kaapuni hydraulic e hana i kahi ʻōnaehana hoʻohui: hoʻololi ka mana mana i ka ikehu mechanical i ka ikehu hydraulic, hoʻoili ka wai hana i ka ikehu i ka actuator, hoʻoponopono ka pūʻulu mana i nā palena o ka ikehu, a ʻo ka ʻāpana kōkua e hōʻoia i ka maikaʻi o ka lawe ʻana i ka ikehu. Hiki i kēia "mechanoelectrohydraulic integration" nā ʻōnaehana hydraulic e hōʻike i nā pono hiki ʻole ke hoʻololi ʻia i ka hana koʻikoʻi, kiʻekiʻe{3}} pololei, a me nā kūlana hana paʻakikī, e hoʻolilo iā lākou i "nā ʻiʻo mana" a me "nā aʻalolo hoʻomalu" o ka ʻoihana hou.

I ka wā e hiki mai ana, me ka hoʻomohala ʻana i ka ʻenehana akamai (e like me ka valve hydraulic kikohoʻe), māmā (e like me ka pahu waiwai composite) a me ka ʻōmaʻomaʻo (e like me ka wai-hydraulic fluid), e ulu ana nā ʻāpana hydraulic i ʻoi aku ka maikaʻi, haʻahaʻa ka hoʻohana ʻana i ka ikehu a me ka lōʻihi o ke ola, e hoʻonui hou i kā lākou noi i nā lako ikehu hou, nā robots humanoid a me nā kahua ʻoki ʻoki.

Aloha ʻoe, ʻo wau ʻo Jason Wang, ka mea kākau o kēia pou. Loaʻa iā mākou ma mua o 15 mau makahiki o ka ʻike ma ka hoʻolako ʻana i nā ʻāpana excavator, e hāʻawi ana i nā ʻāpana kiʻekiʻe -kiʻekiʻe i nā ʻoihana ma nā ʻāina he 50 a puni ka honua. Mai nā hale kūʻai liʻiliʻi liʻiliʻi a hiki i nā mea hoʻolaha nui, hilinaʻi kā mākou mea kūʻai aku iā mākou no nā ʻāpana excavator paʻa a pololei i kūpono i nā kūlana ʻoihana. ʻO kā mākou papa hana nui e pili ana i nā hui excavator, nā puʻu kāpili, nā ʻāpana hydraulic, nā kānana, nā ʻāpana uila, nā ʻāpana undercarriage, a me nā mea hou aʻe, e uhi ana i nā ʻano mea like ʻole a me nā hiʻohiʻona. Inā no ke kūkulu ʻana, ka mining, ka mahiʻai, a i ʻole nā ​​noi mīkini kaumaha, ua kūkulu ʻia kā mākou mau ʻāpana e kū i nā kūlana hana koi, e hōʻoiaʻiʻo ana i ka hana hilinaʻi a me ke ola lawelawe lōʻihi.
