ʻO nā ʻāpana mīkini mining ʻenekinia Hydraulic valve pahu pahu pale kaulike RPGE-LCN

ʻO ka hydraulic valve kahi mea hana maʻalahi me ka ʻaila kaomi, hoʻomalu ʻia e ka ʻaila kaomi valve pressure, i hui pū ʻia me ka valve electromagnetic pressure, hiki ke hoʻohana ʻia no ka mana mamao o ka ʻaila hydropower station, gas, wai pipeline system. Hoʻohana maʻamau no ka hoʻopaʻa ʻana, hoʻomalu, lubrication a me nā kaapuni aila ʻē aʻe. Aia nā ʻano hana pololei a me ke ʻano paionia, ʻano paionia hoʻohana nui. Hoʻohana nui ʻia ka hana o ka valve hydraulic e hōʻemi a hoʻopaʻa i ke kaomi ʻaila o kahi lālā i loko o ka ʻōnaehana, a hoʻohana pinepine ʻia no ka hoʻopili ʻana, hoʻomalu, lubricating a me nā kaʻa ʻaila ʻē aʻe. Aia nā ʻano neʻe pololei, ʻano alakaʻi a me ke ʻano superposition. He ʻāpana i hoʻohana ʻia i ka hoʻoili hydraulic e hoʻomalu i ke kaomi, kahe, a me ke kuhikuhi o ka wai. Ua kapa ʻia ka valve mana kaomi ʻo ka valve control valve, ua kapa ʻia ka valve control valve ka valve control valve, a ʻo ka control on, off and flow direction ka inoa ʻo ka pahu kuhikuhi kuhikuhi. Ka hoʻokaʻawale ʻana o nā valve hydraulic: hoʻokaʻawale ʻia e ka hana: kahe kahe (throttle valve, speed regulating valve, diverter valve, collecting valve, diverter collecting valve), pressure valve (relief valve, pressure reducing valve, sequence valve, unloading valve), direction valve ( ka pahu hoʻohuli electromagnetic, ka pahu hoʻohuli lima, ka valve nānā, ka valve mana hydraulic)

Loaʻa nā pahu hoʻomaha pilot ma nā ʻano hoʻonohonoho like ʻole. He ʻekolu ʻāpana concentric structure pilot relief valve, i haku ʻia i ʻelua ʻāpana: pilot valve a me ka valve nui.

ʻO ka valve pilote taper, ka lua hoʻoheheʻe (hole throttle paʻa) ma ka spool valve nui a me ke kaomi hoʻoponopono pūnāwai e hui pū i ka hapalua-alahaka hapa kaomi ʻāpana mana manaʻo maikaʻi ʻole. hoʻoponopono kaomi i ke keʻena luna o ka spool valve nui. ʻO ka spool nui ka mea hoʻohālikelike o ka loop control main. ʻO ka maka hope luna ma ke ʻano he mana kauoha o ka spool nui, ʻoiai ʻo ka ʻaoʻao haʻahaʻa e hana ma ke ʻano he kaomi ana o ka ʻili o ka loop nui a hana ʻo ia ma ke ʻano he mana manaʻo. Hiki i ka hopena ke hoʻokele i ka spool, hoʻoponopono i ka nui o ke awa overflow, a hoʻokō i ke kumu o ka hoʻoponopono ʻana a me ka hoʻoponopono ʻana i ke kaomi o ke kaomi inlet P1.
