Zida zamakina opangira migodi ya Hydraulic valve cartridge kusanja valveCBBD-LJN

Makhalidwe aukadaulo a valve yothandizira

Valavu yowongolera yoyendetsedwa ndi oyendetsa ndege nthawi zambiri imakhala yotsekeka yowongolera ma valve. Pamene kulowetsedwa (doko 1) kukakamiza kufika pamtengo wa valve, valavu imayamba kusefukira ku thanki yamafuta (doko 2) ndi throttle kuti isinthe kupanikizika. Valavu yamtunduwu imakhala ndi kusinthasintha kwamphamvu kwambiri, kusinthasintha kwapang'onopang'ono ndi kuthamanga kwa kuthamanga, kusintha kosalala, phokoso laling'ono komanso kuthamanga kwapang'onopang'ono.
Ma valve onse a 2-port (kupatula ma valve oyendetsa ndege) amatha kusinthana mu kukula ndi ntchito (mwachitsanzo, valavu yopatsidwa ya kasinthidwe imakhala ndi njira yothamanga yofanana, jack yemweyo).

Angathe kuvomereza Zda kuthamanga pakamwa 2; Zoyenera kugwiritsidwa ntchito mumayendedwe osefukira amafuta padoko lodutsa. Ngati agwiritsidwa ntchito pamzere wamafuta osefukira padoko lodutsa, lingalirani za kutayikira kwa spool.

Z-min yakhazikitsidwa ku 75psi(5bar) pamitundu yonse yamasika.
Sikoyenera kugwiritsidwa ntchito potseka katundu chifukwa cha kutayikira kwa valavu ya slide.
Kuthamanga kumbuyo kwa doko la thanki (doko 2) kumawonjezeka mwachindunji 1: 1 ku mtengo wa valve.
Mabowo akunyowa a siteji yayikulu amatetezedwa ku kuipitsidwa.
Mavavu a cartridge okhala ndi zisindikizo za EPDM atha kugwiritsidwa ntchito mumayendedwe amafuta a phosphate ester hydraulic. Kuwonetsedwa ndi madzi amadzimadzi opangidwa ndi petroleum kapena mafuta opaka mafuta kumatha kuwononga mphete yosindikizira.

Mapangidwe oyandama amachepetsa kuthekera kwa ziwalo zamkati chifukwa cha torque yokwera kwambiri kapena zolakwika za makina a jack/cartridge valve.

Udindo wake wa ma hydraulic valves

Pali mitundu yosiyanasiyana ya ma hydraulic valves, ndipo amasungabe mfundo zina zofanana. Mwachitsanzo:
(1) Mwadongosolo, ma valve onse amapangidwa ndi thupi la valve, spool (valvu ya rotary kapena slide valve), ndi zinthu ndi zigawo (monga akasupe ndi maginito amagetsi) zomwe zimayendetsa ntchito ya spool.
(2) Pankhani ya mfundo yogwirira ntchito, mgwirizano pakati pa kukula kwa ma valve onse otsegulira, kusiyana kwapakati pakati pa kulowetsa ndi kutuluka kwa valve ndi kutuluka kwa valve kumagwirizana ndi kutuluka kwa orifice.
Magawo okhawo owongolera ma valve osiyanasiyana ndi osiyana.

Valve ya Hydraulic ndi gawo lodziwikiratu lomwe limayendetsedwa ndi mafuta oponderezedwa, limayendetsedwa ndi mafuta othamanga, omwe nthawi zambiri amaphatikizidwa ndi ma electromagnetic pressure valve, amatha kugwiritsidwa ntchito kuwongolera kutali kwamafuta a hydropower station, gasi, mapaipi amadzi. Amagwiritsidwa ntchito ngati clamping, control, lubrication ndi zina zozungulira mafuta. Pali mtundu wa zochita zachindunji ndi mtundu wa upainiya, wogwiritsa ntchito zambiri. Udindo wa hydraulic valve umagwiritsidwa ntchito makamaka kuchepetsa ndi kukhazikika kwa mphamvu ya mafuta a nthambi m'dongosolo, ndipo nthawi zambiri amagwiritsidwa ntchito popanga, kulamulira, kudzoza mafuta ndi maulendo ena amafuta. Pali mwachindunji kusuntha mtundu, kutsogolera mtundu ndi superposition mtundu. Chigawo chomwe chimagwiritsidwa ntchito potumiza ma hydraulic kuwongolera kuthamanga, kuyenda, ndi komwe zakumwa. Valve yowongolera kuthamanga imatchedwa valve control valve, valve control valve imatchedwa valve control valve, ndipo kuwongolera, kutsika ndi kuwongolera kumatchedwa valavu yowongolera. Gulu la ma hydraulic valves: gulu ndi ntchito: valavu yothamanga ( valve yothamanga, valavu yoyendetsa liwiro, valavu ya diverter, valavu yosonkhanitsa, valavu yosonkhanitsa), valavu yamagetsi (valavu yothandizira, valavu yochepetsera, valavu yotsatizana, valavu yotsitsa), valavu yotsogolera ( valavu yamagetsi yamagetsi, valavu yosinthira pamanja, valavu yoyang'ana, valavu yoyang'anira ma hydraulic control)
