ʻO nā ʻāpana mīkini mining ʻenekinia Hydraulic valve pahu pahu kaulike kaulikeCBBD-LJN

Nā hiʻohiʻona ʻenehana o ka pahu hoʻomaha

Paʻa maʻamau ka valve hoʻoponopono puʻupuʻu i hoʻomalu ʻia i ka pailaka, paheʻe kaulike. Ke piʻi ke kaomi inlet (port 1) i ka waiwai hoʻonohonoho valve, hoʻomaka ka pahu e kahe i ka pahu wahie (port 2) a me ka throttle e hoʻoponopono i ke kaomi. ʻO kēia ʻano valve he kiʻekiʻe kiʻekiʻe ka hoʻoponopono pololei ʻana, ka liʻiliʻi liʻiliʻi me ka kahe kahe, ka hoʻoponopono maʻalahi, ka walaʻau liʻiliʻi a me ka wikiwiki pane haʻahaʻa.
Hiki ke hoʻololi i ka nui a me ka hana o nā pahu hoʻomaha 2-puka (koe naʻe nā pahu hoʻomaha hoʻokele) (e laʻa, he ala kahe like ka pahu hoʻonohonoho hoʻonohonoho i hāʻawi ʻia, ʻo ia ka jack hoʻokahi).

Hiki ke ʻae i ke kaomi Zda ma ka waha 2; He kūpono no ka hoʻohana ʻana i ka ʻaila kaapuni o ke awa kea. Inā hoʻohana ʻia i loko o kahi laina ʻaila nui ma ke awa kea, e noʻonoʻo i ka leaka spool.

Hoʻonohonoho ʻia ʻo Z-min i 75psi (5bar) no nā pae puna a pau.
ʻAʻole kūpono no ka hoʻohana ʻana i nā noi hoʻopaʻa ukana ma muli o ka leakage o ka pahu paheʻe.
Hoʻonui pololei ʻia ke kaomi hope ma ke awa pahu (port 2) i ka 1: 1 i ka waiwai i hoʻonohonoho ʻia o ka valve.
Mālama ʻia nā puka uʻi o ke kahua nui mai ka haumia.
Hiki ke hoʻohana ʻia nā pahu pahu pahu pahu me nā sila EPDM i nā ʻōnaehana ʻaila hydraulic ester phosphate. Hiki ke hoʻopōʻino i ke apo o ka sila ka ʻike ʻana i nā wai hydraulic e pili ana i ka ʻaila a i ʻole nā ​​aila lubricating.

Hoʻemi ka ʻōnaehana lana i ka hiki ke hoʻopaʻa ʻia nā ʻāpana o loko ma muli o ka nui o ka hoʻouka ʻana i ka torque a i ʻole nā ​​hewa mīkini o ka pahu jack/cartridge valve.

ʻO ia ke kuleana o nā valve hydraulic

Loaʻa nā ʻano ʻano like ʻole o nā valve hydraulic, a ke mālama mau nei lākou i kekahi mau kumu maʻamau. ʻo kahi laʻana:
(1) Ma ke ʻano, ua haku ʻia nā kiwi a pau me ke kino valve, kahi spool (valve rotary a slide valve), a me nā mea a me nā ʻāpana (e like me nā pūnāwai a me nā electromagnets) e hoʻokele i ka hana spool.
(2) Ma ke ʻano o ka loina hana, ʻo ka pilina ma waena o ka nui o ka wehe ʻana o nā valve a pau, ʻo ka ʻokoʻa o ke kaomi ma waena o ka inlet a me ka puka o ka valve a me ke kahe ʻana o ka valve e like me ke kahe orifice.
ʻOkoʻa wale nā ​​palena o nā mana valve like ʻole.

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)
