一、 Gulu la ma hydraulic valves

1. Valavu yolowera: imayendetsa kayendedwe ka mafuta a hydraulic

Vavu yolunjikandiye valavu yofunikira kwambiri mu hydraulic system, yomwe imagwiritsidwa ntchito makamaka kuwongolera kayendedwe ka mafuta a hydraulic. Mitundu yodziwika bwino ya ma valve olowera ndi:

•Valavu yotsogolera pamanja: Yoyendetsedwa ndi chogwirira kapena batani, kugwira ntchito ndikosavuta komanso mwachilengedwe.

•Electro-hydraulic directional valve: yoyendetsedwa ndi ma siginecha amagetsi, imatha kuwongolera kutali komanso kuwongolera.

•Valavu yowongolera ya Hydraulic: Imayendetsedwa ndi ma siginecha a hydraulic, omwe nthawi zambiri amagwiritsidwa ntchito pakuwongolera mndandanda kapena kuwongolera njira zambiri.

Mavavu owongolera amagwiritsidwa ntchito kwambiri pamakina osiyanasiyana a hydraulic, monga zofukula, ma bulldozers, makina osindikizira a hydraulic, etc.

2. Valavu yopondereza: imayendetsa kupanikizika kwa hydraulic system

Thevalve pressureamagwiritsidwa ntchito makamaka kuti athetse kupanikizika kwa ma hydraulic system kuti ateteze kupanikizika kwapamwamba kapena kutsika kwambiri kuti ateteze makina a hydraulic ndi zipangizo. Mitundu yodziwika bwino ya valve pressure ndi:

•Valavu yothandizira: Pamene kupanikizika kwa hydraulic system kupitirira mtengo woikidwiratu, valavu yothandizira imatseguka kuti itulutse gawo la mafuta a hydraulic ndi kuchepetsa kupanikizika.

•Valavu yochepetsera kupanikizika: Imachepetsa kuthamanga kwa mafuta othamanga kwambiri a hydraulic mpaka kutsika komwe kumafunikira, komwe nthawi zambiri kumagwiritsidwa ntchito poyang'anira mndandanda kapena kuwongolera njira zambiri.

•Valavu yotetezera: Pamene kupanikizika kwa hydraulic system kumakwera mosadziwika bwino, valavu yotetezera imatsegula ndikutulutsa mafuta onse a hydraulic kuti ateteze kuwonongeka kwa dongosolo.

Ma valve opanikizika amagwiritsidwa ntchito kwambiri pamakina osiyanasiyana a hydraulic, monga makina opangira jakisoni, masilinda a hydraulic, ma hydraulic motors, ndi zina zambiri.

3. Valve yoyenda: imayendetsa kayendedwe ka mafuta a hydraulic

Thevalve yotuluka amagwiritsidwa ntchito makamaka poyang'anira kayendedwe ka mafuta a hydraulic kuti atsimikizire kuti makina a hydraulic amatha kupereka mafuta a hydraulic pakufunika. Mitundu yodziwika bwino ya valve yothamanga ndi:

•Valve ya Throttle: Imawongolera kuyenda mwa kusintha kukula kwa dzenje la throttle, ndipo imakhala ndi magwiridwe antchito abwino.

•Valavu yothandizira: Pamene kuthamanga kwathamanga kupitirira mtengo woikidwiratu, valavu yothandizira imatseguka kuti itulutse gawo la mafuta a hydraulic ndikuchepetsa kuthamanga.

•Valavu yofananira: Imatha kusintha kuchuluka kwa kuthamanga molingana ndi kuchuluka kwa chizindikiro cholowera kuti ikwaniritse kuwongolera kolondola kwambiri.

Ma valve oyenda amagwiritsidwa ntchito kwambiri pamakina osiyanasiyana a hydraulic, monga ma hydraulic transmission systems, hydraulic control systems, etc.

4. Ma valve ena apadera

Kuphatikiza pa mitundu yodziwika bwino ya ma hydraulic valves omwe atchulidwa pamwambapa, palinso ma hydraulic valves okhala ndi ntchito zapadera, monga:

•Vavu yobwerera: Imasintha mwachangu njira yoyendetsera mafuta a hydraulic, omwe nthawi zambiri amagwiritsidwa ntchito pamakina otumizira ma hydraulic.

•Valavu yotsatizana: Imayang'anira kutuluka kwa mafuta a hydraulic motsatizana zodziwikiratu ndipo nthawi zambiri amagwiritsidwa ntchito munjira zambiri zowongolera.

•Ma valve ophatikizira: Phatikizani ma valve angapo palimodzi kuti mukwaniritse ntchito zowongolera zovuta.

Ma valve apaderawa nthawi zambiri amagwiritsidwa ntchito pazochitika zinazake kuti akwaniritse zosowa zapadera.

二、 Njira Yachitukuko ya Hydraulic Valve

Ndi kupita patsogolo kwaukadaulo komanso kufunikira kowonjezereka, ma hydraulic mavavu amakhazikika m'njira yanzeru, yothandiza, yosamalira chilengedwe komanso yodalirika.

•Anzeru: Mavavu a Hydraulic atenga ukadaulo wowongolera mwanzeru kuti akwaniritse kuwongolera kolondola, kothandiza komanso kosinthika.

•Kuchita bwino kwambiri: Mavavu a Hydraulic atenga ukadaulo wopulumutsa mphamvu kuti apititse patsogolo magwiridwe antchito komanso kuchepetsa kugwiritsa ntchito mphamvu.

•Kuteteza chilengedwe: Mavavu a Hydraulic adzagwiritsa ntchito zida zoteteza chilengedwe komanso njira zochepetsera kuwononga chilengedwe.

•Kudalirika: Ma valve a Hydraulic atenga mapangidwe odalirika kwambiri ndi njira zopangira kuti apititse patsogolo kudalirika ndi moyo wautumiki wa dongosolo.

Kukula kosiyanasiyana kwa ma hydraulic valve kubweretsa malo okulirapo a makina a hydraulic ndi magawo ena ogwiritsira ntchito, ndikuthandizira kukwaniritsa zolinga monga makina opanga mafakitale, kupanga mwanzeru, ndi chitukuko chobiriwira.
