I nā ʻōnaehana mana hydraulic, ʻelua mau ʻenehana koʻikoʻi nā radial piston pumps a me axial piston pumps, e noho ana i nā kahua noi like ʻole me kā lākou hoʻolālā hoʻolālā kū hoʻokahi a me nā hiʻohiʻona hana. ʻOiai ʻike lāua ʻelua i ka hoʻololi ʻana o ka ikehu wai ma o ka neʻe ʻana o ka piston, aia nā ʻokoʻa nui i ko lākou ʻano kūloko, nā hiʻohiʻona hana a me nā hiʻohiʻona pili.
Nā ʻokoʻa kumu kumu: "radial" a me "parallel" hoʻonohonoho o nā pistons
1. ʻO ka pauma piston radial hydraulic: ua puunaueia na pistons
Nā hiʻohiʻona hoʻolālā: Hoʻonohonoho ʻia nā pistons ma ke ʻano hōkū ma ka ʻaoʻao radial o ke kumu hoʻokele (e like me nā ʻōlelo huila), kū pololei i ke kumu nui.
Kuʻina hana: Ua kokoke ka piston i ke apo cam eccentric (Cam Ring) ma o ka ikaika centrifugal a i ʻole ka pahu mechanical. I ka wā e hoʻohuli ai ka rotor, hoʻihoʻi ka piston i ka puka radial e hoʻopau i ke kaʻina hana ʻaila a me ke kaomi ʻaila.
Nā mea nui: eccentric cam ring, rotor cylinder, distribution shaft.
2. ʻO ka pauma piston hydraulic axial: ua hoʻonohonoho ʻia ka piston e like me ke kumu nui.
Nā hiʻohiʻona hoʻolālā: Ua like ka piston me ke kumu hoʻokele a puʻunaue like ʻia i ka cylinder rotating.
Kuʻuna hana: Loaʻa i ka plunger ka neʻe pānaʻi ʻana ma o ke kihi inclination o ka swashplate a i ʻole ke axis piko. ʻO ka ʻoi aku ka nui o ke kihi swashplate, ʻoi aku ka lōʻihi o ka paʻi plunger a ʻoi aku ka kiʻekiʻe o ke kahe puka.
Nā mea koʻikoʻi: swashplate/pipe axis, rotating cylinder, distributor plate.
Hoʻohālikelike ʻike:
ʻO ka pāpaʻi Radial: ʻOi aku ka "paʻa" o ke ʻano, kūpono no ke kaomi kiʻekiʻe kiʻekiʻe, akā ʻoi aku ka nui o ka leo.
Axial pump: ʻOi aku ka "compact" o ke ʻano, kūpono no ka wikiwiki kiʻekiʻe, ka mana hoʻololi, a ʻoi aku ka kiʻekiʻe o ka mana.
Hoʻohālikelike hana: kaomi, pono, ola a me ka walaʻau
1. Hiki ke kaomi
ʻO ka paila piston Radial: Hoʻolālā ʻia no ka puʻe kiʻekiʻe kiʻekiʻe (ma luna o 600-1000 bar), e like me nā kaomi hydraulic, nā lako kai hohonu a me nā kūlana hana koʻikoʻi.
Axial piston pump: He 200-450 bar ka nui o ke kaomi nui, a hiki i kekahi mau hiʻohiʻona kiʻekiʻe ke hiki i ka 600 bar, kūpono i nā mīkini hana, nā mīkini hoʻoheheʻe injection, etc.
Ka hopena: Inā ʻoi aku ka nui o ke koi ʻana o ka ʻōnaehana ma mua o 500 bar, ʻo ka pā radial wale nō ke koho; inā aia ma lalo o 400 bar, ʻoi aku ka maikaʻi o ka pā axial.
2. Paʻa a me ka walaʻau
ʻO ka pāpaʻi Radial: ʻoi aku ka liʻiliʻi o nā plungers (maʻa mau 5-7), ʻoi aku ka nui o ke kahe kahe ʻana, ka leo kiʻekiʻe (ma luna o 80 dB).
ʻO ka pauma Axial: ʻoi aku ka nui o nā plungers (7-9 a ʻoi aku paha), ʻoi aku ka maikaʻi o ka puka kahe, haʻahaʻa haʻahaʻa (70-75 dB).
Ka hopena o ka hoʻohana ʻana: ʻOi aku ka maikaʻi o nā pāpaʻi Axial no nā hiʻohiʻona pili i ka walaʻau (e like me nā mea lapaʻau a me nā mea hana mīkini pololei).
3. ʻO ka maikaʻi a me ka mana hoʻololi
ʻO ka pauma Radial:
ʻO ka maikaʻi mechanical kiʻekiʻe (92%+), akā paʻakikī hoʻololi hoʻololi, hoʻoponopono cam eccentricity, pane lohi.
He kūpono no ka hoʻoneʻe paʻa ʻana a i ʻole nā kūlana haʻahaʻa haʻahaʻa a me nā kūlana kiʻekiʻe.
ʻAxial pump:
ʻO ka hoʻokō volumetric kiʻekiʻe (95%+), ka mana hoʻololi maʻalahi (ma ka hoʻoponopono ʻana i ke kihi o ka pā swash), a me ka pane wikiwiki.
He kūpono no ka hoʻoponopono ʻana i ka wikiwiki a me nā ʻōnaehana mālama ikehu (e like me nā excavators a me nā ʻōnaehana pitch variable pitch).
4. Ola a mālama
ʻO ka pāpaʻi Radial: ka hana maʻalahi, ke kūpaʻa ʻana o ka pollution ikaika, kūpono no nā wahi ʻino (e like me ka mīkini mining).
Axial pump: He kiʻekiʻe nā koi no ka hoʻomaʻemaʻe ʻaila a me ka hoʻomaʻemaʻe ʻaila a koi ʻia ka kānana maikaʻi (NAS 1638 Class 6 a i ʻole).
Hoʻohālikelike i nā hiʻohiʻona noi maʻamau
1. ʻO ke kahua kaua nui o nā radial piston pumps
Pūnaehana hydraulic puʻe kiʻekiʻe kiʻekiʻe:
Ka hana metala (hydraulic press, forging press)
Nā lako kai hohonu (ROV hydraulic power)
ʻOihana koa (submarine hydraulic system)
Kaiapuni loa:
Mīkini mining (kū'ē i ka pollution, kū'ē i ka hopena)
ʻO ka ʻaila ʻaila (pāmi lepo kiʻekiʻe)
2. ʻO ke kahua nui o nā paila piston axial
Nā lako hydraulic mobile:
Nā mīkini hana (excavator, loader)
Mīkini mahiʻai (hui hui)
ʻOihana ʻenehana:
Mīkini hoʻoheheʻe ʻia, mīkini hoʻoheheʻe make
Pūnaehana pitch variable mana makani
Aerospace:
Pūnaehana hydraulic pae mokulele
Nā ʻano mākeke a me nā kuhikuhi hoʻomohala e hiki mai ana
1. Nā holomua ʻenehana o nā paila axial
ʻO ke kaomi kiʻekiʻe: Ua hoʻokumu kekahi mau mea hana (e like me Bosch Rexroth a me Parker Hannifin) i 600 bar axial pumps e hoʻokūkū i nā pono kuʻuna o nā pamu radial.
Ka mana naʻauao: nā mea ʻike i hoʻohui ʻia e hoʻokō i ka hoʻoponopono manawa maoli o ka kahe a me ke kaomi (IoT hydraulic system).
2. Ireplaceability o radial pumps
Ke hoʻomau nei ka mākeke 1000 bar+ e nā radial pumps, e like me ka ʻoki wai kiʻekiʻe kiʻekiʻe a me nā mea hana metallurgical kūikawā.
Ka holomua waiwai: hoʻonui ke ola i nā plungers seramika a me nā pūpū kalapona i hoʻoikaika ʻia.
3. ʻO ka palekana o ke kaiapuni a me ka pono o ka ikehu e hoʻoikaika i ka hana hou
ʻOi aku ka maikaʻi o nā pāpaʻi Axial me nā pono e mālama i ka ikehu ma lalo o ka pahuhopu "dual carbon" ma muli o kā lākou mau hiʻohiʻona hoʻololi kiʻekiʻe.
Ua loaʻa i nā pāpaʻi Radial nā wahi ulu hou i ka ikehu hou (e like me nā ʻōnaehana hydraulic hoʻoulu mana tidal).
ʻO nā paila piston Radial a me nā paila piston axial e hōʻike ana i ʻelua mau manaʻo o ka ʻenehana hydraulic:
ʻO nā pāpaʻi Radial nā "mea pāʻani mana" i hoʻolālā ʻia no nā hiʻohiʻona kiʻekiʻe kiʻekiʻe a me nā hiʻohiʻona hilinaʻi kiʻekiʻe;
ʻO nā pāpaʻi axial he "mea pāʻani holoʻokoʻa" me ka ʻoi aku ka maikaʻi, ka mana a me ka compactness.
Inā loaʻa iā ʻoe kekahi mea e pono ai, e ʻoluʻolu e kelepona i ka mea hana hydraulic poocca.
