Excavator PC160-7 PC200-7 Vavu yachitetezo 723-90-61300 valavu yothandizira ma hydraulic valve

Mfundo yogwira ntchito ya valve solenoid:

Valavu yamagetsi yamagetsi yofukula ndi chinthu chodziwikiratu chomwe chimagwiritsidwa ntchito kuwongolera madzi ofufutira, omwe ndi a actuator, ndipo samangokhala ndi ma hydraulic ndi pneumatic. Amagwiritsidwa ntchito m'makina owongolera mafakitale kuti asinthe njira ya media, kuyenda, kuthamanga ndi magawo ena.

Valve ya solenoid ikhoza kuphatikizidwa ndi mabwalo osiyanasiyana kuti akwaniritse chiwongolero chomwe akufuna, ndipo kulondola ndi kusinthasintha kwa kuwongolera kumatha kutsimikizika. Pali mitundu yambiri ya ma valve a solenoid, ma valve osiyana a solenoid amagwira ntchito m'malo osiyanasiyana a kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, ndi zina zotero.

1, kusiyana pakati pa valavu yamagetsi ndi valavu ya solenoid
Solenoid valve ndi maginito koyilo pambuyo poti koyilo yamagetsi ipatsidwa mphamvu kuti ipangitse kukopa kwa maginito kuti igonjetse kukakamiza kwa kasupe kuyendetsa spool, koyilo ya solenoid, kapangidwe kosavuta, mtengo wotsika mtengo, ukhoza kungokwaniritsa kusintha;
Valavu yamagetsi imayendetsa tsinde la valavu kudzera mugalimoto kuti iyendetse spool, ndipo valavu yamagetsi imagawidwa kukhala (valavu yotseka) ndi valavu yowongolera. Valve yotseketsa ndi mtundu wa ntchito ziwiri zomwe zimatseguka komanso kutsekedwa kwathunthu, ndipo valavu yoyang'anira imayikidwa pamagetsi amagetsi amagetsi, zomwe zimapangitsa kuti valve ikhale yokhazikika pamtunda kupyolera mu kusintha kotsekedwa.

2, valavu yamagetsi ndi valavu yogwiritsira ntchito solenoid
Valavu ya Solenoid: Imagwiritsidwa ntchito posinthira mizere yamadzi ndi gasi, ili ndi magawo awiri DO kuwongolera. Nthawi zambiri amagwiritsidwa ntchito poyang'anira chitoliro chaching'ono.
Vavu yamagetsi: Kwa madzi, gasi ndi makina oyendetsa mapaipi apakati osinthira analogi, ndikuwongolera kwa AI. Poyang'anira ma valve akuluakulu ndi machitidwe a mphepo, ma valve amagetsi angagwiritsidwenso ntchito ngati njira ziwiri zosinthira kusintha.
Valavu ya Solenoid: ingagwiritsidwe ntchito ngati kuchuluka kwa kusintha, ndi kuwongolera kwa DO, ingagwiritsidwe ntchito powongolera zitoliro zazing'ono, zomwe zimapezeka mu DN50 ndi pansi pa mapaipi.
Vavu yamagetsi: ikhoza kukhala ndi zizindikiro za AI, ikhoza kulamulidwa ndi DO kapena AO, poyerekeza ndi mapaipi akuluakulu ndi ma valve a mphepo.
