Wehe maʻamau ʻōnaehana hydraulic e hoʻohuli ana i ka valve solenoid SV-08

ʻO nā ʻāpana maʻalahi e hoʻopuka i ka walaʻau i loko o nā mea hydraulic e manaʻo ʻia e like me nā pumps a me nā valves, a ʻo nā valves ka nui o nā valves a me nā valve directional electromagnetic.Nui nā kumu e hoʻopuka ai i ka walaʻau.ʻElua ʻano o ka walaʻau o ka valve overflow: kani velocity a me ke kani mechanical.ʻO ka walaʻau i ke kani wikiwiki ke kumu nui ʻia e ka ʻaila vibration, cavitation a me ka hopena hydraulic.ʻO ka walaʻau mīkini ka mea nui ma muli o ka hopena a me ka friction o nā ʻāpana o ka valve.

(1) Ka walaʻau ma muli o ke kaomi ʻole

ʻO ka ʻaoʻao o ka valve pilote o ka valve relief pilote he wahi maʻalahi ia e like me ka mea i hōʻike ʻia ma ka Figure 3. I ka wā e kahe ana ma lalo o ke kaomi kiʻekiʻe, he liʻiliʻi loa ka wehe axial o ka valve pilote, ʻo 0.003 ~ 0.006 cm wale nō.He liʻiliʻi loa ka wahi kahe, a he kiʻekiʻe loa ka wikiwiki o ke kahe, hiki ke piʻi i 200m / s, hiki ke maʻalahi i ka puʻupuʻu puʻupuʻu ʻole, ka ikaika radial ʻole o ka cone valve a me ka haʻalulu.Eia kekahi, ʻo ka ellipticity i hoʻokumu ʻia e ka mīkini ʻana o ka valve cone a me ka noho valve cone, ʻo ka pipili ʻana o ka lepo o ke awa valve pilote a me ka deformation o ka pūnāwai hoʻoponopono kaomi e hoʻoulu ai i ka vibration o ka valve cone.No laila, manaʻo ʻia ʻo ka valve pilot ke kumu haʻalulu o ka walaʻau.

Ma muli o ke ʻano o ka elastic element (spring) a me ka neʻe ʻana o ka nui (cone valve), he ʻano ia no ka oscillation, a ʻo ka lua mua o ka valve pilot e hana ma ke ʻano he resonant cavity, no laila ua maʻalahi ka haʻalulu o ka valve cone. ka resonance o ka valve holoʻokoʻa a me ka walaʻau, ka mea maʻamau e hui pū ʻia me ka lele kaomi koʻikoʻi.
