ʻO ka ʻike kumu o ka mīkini hydraulic a me nā sila ʻanuʻu i nā pamu

Hoʻokumu ʻia ka sila ʻanuʻu me ka sila ʻanuʻu a me ka O-ring.
ʻO ka hana a me ka hilinaʻi o nā mīkini hydraulic a me nā pumps e hilinaʻi nui ʻia i ka hana ʻana o nā sila, ʻo ia ka piston rod seal a me ka piston seal nā mea hoʻopaʻa maʻamau.ʻO nā sila hoʻohui ʻanuʻu (step seals a me nā sila O-ring sila) kekahi o nā sila lāʻau piston maʻamau i hoʻohana ʻia a hoʻohana ʻia i nā sila piston.
Mīkini Hydraulic and pump i ka hui ʻanuʻu o nā sila i kāna mau hiʻohiʻona hana:

ʻO nā sila piston hydraulic no nā sila hui ʻanuʻu

1. Pumi ≤(MPa): 60/MPa
2. Ka wela: -45 ℃ i + 200 ℃
3. Ka māmā holo ≤(m/s): 15 m/s
4. Mea hoʻopaʻa paʻa: NBR/PTFE FKM
5. Hoʻohana nuiʻia ma: piston rod i ka mīkini hydraulic, ka cylinder maʻamau, ka mīkini mīkini, ka mīkini hydraulic, etc.

Ma keʻano he mea hoʻopaʻa kī e like me ka piston rod seal a me ka piston seal, inā he leak, e hoʻopilikia maoli ia i ka hana maʻamau o ka mīkini a hoʻopilikia i ka nohona.No laila, ʻaʻole wale ma lalo o nā hōʻailona static (static) wale nō, akā ma lalo o nā kūlana dynamic (dynamic) sila hiki ke hoʻokō i ka leakage liʻiliʻi.
Eia kekahi, ʻo ka hoʻohana ʻana i ka mana friction a me ka hoʻohana ʻana i ke ola o nā mea hoʻopaʻa paʻa i ka hopena nui i ka maikaʻi o ka hana o ka ʻōnaehana mechanical.ʻO ka leakage, ka hoʻohana ʻana i ka mana, ke ola ola a me nā mea nui ʻē aʻe o ka sila hoʻohui stepped a me nā waiwai mechanical o ka sila ma lalo o nā kūlana hana e pili kokoke ana i ke kaomi a me ka hāʻawi ʻana i ka ʻili pili ma waena o ka sila a me ke koʻokoʻo piston (a i ʻole ka paia cylinder. ).ʻO ia e pili ana i ka mana o nā ʻōnaehana hana ʻōnaehana mechanical i nā waiwai mechanical a me nā kūlana hana o nā sila.
