Pono e hoʻokō ka mea kānana aila hydraulic i nā koi o ka poho puʻe (ʻo ka nui o ka ʻokoʻa ʻokoʻa o ka kānana kiʻekiʻe ma lalo o 0.1PMa, a ʻo ka nui o ka ʻokoʻa ʻokoʻa o ka kānana hoʻihoʻi ʻaila ma lalo o 0.05MPa) e hōʻoia i ka optimization o kahe a me ke ola mea kānana. No laila pehea mākou e koho pono ai i ka kānana aila hydraulic? 'Ōlelo ka mea hoʻoponopono iāʻoe e ponoʻoe e noʻonoʻo i kēia mau mea 5:

1. Pono pono kānana

ʻO ka mea mua, e hoʻoholo i ka pae maʻemaʻe o nā stains e like me nā pono o ka ʻōnaehana hydraulic, a laila koho i ka kānana pono o ka kānana aila e like me ka pae maʻemaʻe e like me ka papa hōʻailona. ʻO ka mea kānana aila hydraulic maʻamau i hoʻohana ʻia i nā mīkini hana he 10μm kānana nominal. ʻO ka hoʻomaʻemaʻe ʻaila hydraulic (ISO4406) Ka pololei o ka kānana inoa ʻana o ka mea kānana (μm) Ka laulā noi 13/103 Hydraulic servo valve (me 3μm filter element) 16/135 Hydraulic proportional valve (me 5μm filter element) 18/1510 General hydraulic component (>10MPa ) (me ka mea kānana 10μm) 19/1620 mau mea hydraulic maʻamau (<10MPa) (me ka mea kānana 20μm)

No ka mea, ʻaʻole hiki i ka pololei kānana nominal ke hōʻike maoli i ka mana kānana o ka mea kānana, ʻo ke anawaena o ka ʻāpana spherical paʻakikī nui loa i hiki i ka kānana ke hele ma lalo o nā kūlana hoʻāʻo i ʻōlelo ʻia e hoʻohana pinepine ʻia e like me kona pololei kānana ponoʻī e hōʻike pololei i ka kānana mua o ka. mea kānana hou i hoʻokomo ʻia. ʻO ka mea koʻikoʻi koʻikoʻi no ka loiloi ʻana i ka hiki o ka mea kānana aila hydraulic ʻo ka waiwai β i hoʻoholo ʻia e like me ISO4572-1981E (multi-pass test), ʻo ia hoʻi, ʻo ka ʻaila i hui pū ʻia me ka pauka hoʻāʻo maʻamau e kahe ʻia ma o ka kānana aila no nā manawa he nui. , a aia ka puka aila a me ka puka ʻaila ma nā ʻaoʻao ʻelua o ka kānana aila. lākiō o ka helu o nā ʻāpana.

2. Nā hiʻohiʻona kahe

ʻO ke kahe a me ka hāʻule kaomi o ka mea kānana e hele ana i ka ʻaila he mau palena koʻikoʻi o nā ʻano kahe. Pono e hoʻokō ʻia ka hoʻāʻo ʻano kahe e like me ka ISO3968-91 maʻamau e huki i ka pihi hiʻohiʻona kahe kahe. Ma lalo o ke kaomi aila i helu ʻia, ʻo ka hāʻule ʻana o ke kaomi (ka huina o ka hāʻule kaomi o ka hale kānana a me ka hāʻule kaomi o ka mea kānana) ma lalo o 0.2MPa. ʻO ke kahe kiʻekiʻe: 400lt / min ʻO ka ho'āʻoʻana i kaʻaila viscosity: 60to20Cst Ka liʻiliʻi holoʻana i ka Turbine: 0 ℃ 60lt / min ʻO ke kahe nui o ka turbine: 0 ℃ 400lt / min

3. Ka ikaika kānana

E hoʻokō ʻia ka hōʻike rupture-impact e like me ISO 2941-83. ʻOi aku ka nui o ka ʻokoʻa paʻi e hāʻule nui i ka wā i poino ai ka mea kānana ma mua o ka waiwai i ʻōlelo ʻia.

4. Kahe mau hiʻona luhi

Pono e like me ka ISO3724-90 hoʻāʻo luhi maʻamau. Pono e hoʻāʻo ʻia nā mea kānana no 100,000 pōʻai.

5. Ho'āʻo no ka adaptability o ka aila hydraulic

kānana aila hydraulic

Pono e hoʻokō ʻia ka hoʻāʻo ʻana o ke kahe kahe e like me ka ISO2943-83 maʻamau e hōʻoia i ka hoʻohālikelike ʻana o ka mea kānana me ka aila hydraulic.

ʻO ka ratio kānana b e pili ana i ka ratio o ka nui o nā ʻāpana i ʻoi aku ka nui ma mua o ka nui i hāʻawi ʻia i ka wai ma mua o ka kānana ʻana i ka helu o nā ʻāpana i ʻoi aku ka nui o ka nui o ka wai ma hope o ka kānana ʻana. Nb=ka helu o nā ʻāpana ma mua o ka kānana ʻana Na=ka helu o nā ʻāpana ma hope o ka kānana ʻana X=ka nui o nā ʻāpana.

ʻO ka mea kānana aila hydraulic kahi huaʻōlelo ʻoihana i ka ʻoihana kānana. No ka hoʻomaʻemaʻe ʻana i nā kumuwaiwai kūlohelohe mua a me ka hoʻohana hou ʻana i nā kumuwaiwai, pono nā lako hoʻomaʻemaʻe. I kēia manawa, hoʻohana nui ʻia ka mea kānana i ka kānana aila, kānana ea, kānana wai a me nā ʻoihana kānana ʻē aʻe. ʻO nā mea o ka mea kānana aila hydraulic e komo pū ana me ka mea kānana pepa, ka mea kānana fiber kemika (ke aniani fiber, ka fiber metala sintered feel, polypropylene fiber, polyester fiber) mesh filter element (stainless steel mesh) a me ka line gap filter element. He kūpono ka mea kānana aila hydraulic no ka kānana ʻana i ka waikawa ikaika, ka alkali ikaika a me ka solvent organik. ʻO ka membrane kānana he kānana hohonu i hoʻopili ʻia, he wahi kānana nui, ʻokoʻa haʻahaʻa haʻahaʻa, paʻa lepo ikaika a me ke ola lawelawe lōʻihi. Aia nā hiʻohiʻona like ʻole a me nā kikoʻī e koho ai.
