(1) Hoʻohana ʻia ka ikehu like ʻole

Hiki i nā ʻāpana pneumatic a me nā mea hana ke hoʻohana i ke ʻano o ka hāʻawi ʻana i ka ea kikowaena mai ke kikowaena air compressor, a hoʻoponopono i ke kaomi hana o kēlā me kēia kaomi hoʻohaʻahaʻa i ka valve e like me nā koi hoʻohana ʻokoʻa a me nā wahi mana.Hoʻokomo ʻia nā valve hydraulic me nā laina hoʻihoʻi ʻaila e hoʻomaʻamaʻa i ka hōʻiliʻili ʻana o ka ʻaila hydraulic i hoʻohana ʻia i loko o ka pahu aila.Hiki i ka pneumatic control valve ke hoʻokuʻu pololei i ka ea i hoʻopaʻa ʻia i ka lewa ma o ke awa exhaust.

(2) Nā koi like ʻole no ka leakage

Loaʻa i ka valve hydraulic nā koi koʻikoʻi no ka leakage waho, akā ʻae ʻia kahi liʻiliʻi o ka leakage i loko o ka mea.No nā kīwī hoʻomalu pneumatic, koe wale nā ​​pahu i hoʻopaʻa ʻia, ʻaʻole ʻae ʻia ka leaka o loko ma ke kumu.ʻO ka leaka o loko o ka valve pneumatic hiki ke hoʻopilikia.

No nā paipu pneumatic, ʻae ʻia kahi liʻiliʻi o ka leakage;ʻoiai ka leakage o nā paipu hydraulic e hoʻohaʻahaʻa i ke kaomi ʻōnaehana a me ka haumia o ke kaiapuni.

(3) Nā koi like ʻole no ka lubrication

ʻO kaʻenehana hana o ka'ōnaehana hydraulic heʻaila hydraulic, aʻaʻohe koi no ka lubrication o nā valve hydraulic;ʻO ke ea ka mea hana o ka ʻōnaehana pneumatic, ʻaʻohe lubricity, no laila he nui nā valve pneumatic e koi ai i ka lubrication hinu.Pono e hana ʻia nā ʻāpana valve me nā mea ʻaʻole hiki ke ʻino ʻia e ka wai, a i ʻole e lawe ʻia nā hana anti-rust.

(4) Nā pae kaomi like ʻole

ʻOi aku ka haʻahaʻa o ke kaomi hana o nā valve pneumatic ma mua o nā valve hydraulic.ʻO ke kaomi hana o ka valve pneumatic maʻamau i loko o 10bar, a hiki i kekahi ke hiki i loko o 40bar.Akā he kiʻekiʻe loa ke kaomi hana o ka valve hydraulic (maʻamau i loko o 50Mpa).Inā hoʻohana ʻia ka valve pneumatic ma ke kaomi ma mua o ke kaomi ʻae ʻia.Kū pinepine nā pōʻino koʻikoʻi.

(5) Nā ʻano hoʻohana like ʻole

ʻO ka mea maʻamau, ʻoi aku ka paʻa a me ka māmā o nā valve pneumatic ma mua o nā valve hydraulic, a maʻalahi hoʻi e hoʻohui a hoʻokomo.Loaʻa i ka valve kahi alapine hana kiʻekiʻe a me ke ola lawelawe lōʻihi.Ke ulu nei nā kīpē pneumatic i ka mana haʻahaʻa a me ka miniaturization, a ua ʻike ʻia nā kīwaha solenoid haʻahaʻa me ka mana o 0.5W wale nō.Hiki ke hoʻopili pololei ʻia me kahi microcomputer a me PLC programmable controller, a i ʻole hiki ke hoʻokomo ʻia ma ka papa kaapuni paʻi me nā mea uila.Hoʻopili ʻia ke kaapuni gas-electric ma o ka papa maʻamau, kahi e mālama ai i ka nui o nā uea.He kūpono ia no nā manipulators ʻoihana pneumatic a me ka hana paʻakikī.Nā manawa e like me ka laina hui.
