Kwa R225-7 excavator relief valve 31N6-17400 loader zowonjezera

Valve yothandizira sichikhoza kugwira ntchito ya valavu yotetezera, komanso ingagwiritsidwe ntchito ngati valavu yoyendetsa kuthamanga, valavu yotsitsa, valve yothamanga kumbuyo, valve balance ndi zina zotero. Zotsatirazi ndizofotokozera mwatsatanetsatane za ntchito zisanu ndi ziwiri za valve yothandizira mu hydraulic system.

1. Zotsatira zakusefukira
Pampu yachulukidwe ikagwiritsidwa ntchito popereka mafuta, imalumikizidwa ndi valavu ya throttle kuti isinthe ndikuwongolera kuyenda mu hydraulic system. Pankhaniyi, valavu nthawi zambiri imatsegula ndi kusinthasintha kwa kuthamanga, ndipo mafuta amabwerera ku thanki kupyolera mu valve, yomwe imagwira ntchito yochuluka pansi pa kupanikizika kosalekeza.

2. Sewerani gawo lachitetezo chachitetezo

Pewani ngozi zobwera chifukwa cha kuchuluka kwa ma hydraulic system ndi zida zamakina. Pankhaniyi, valavu nthawi zambiri imatsekedwa, pokhapokha ngati katunduyo akudutsa malire omwe atchulidwa kuti atsegulidwe, amasewera chitetezo chachitetezo. Kawirikawiri, kupanikizika kwa valve yothandizira kumasinthidwa 10 ~ 20% kuposa kupanikizika kwakukulu kwa dongosolo.

3. Amagwiritsidwa ntchito ngati valavu yotsitsa

Valavu yothandizira oyendetsa ndege ndi valavu iwiri ya solenoid ya njira ziwiri ingagwiritsidwe ntchito palimodzi kutsitsa dongosolo.

4. Kwa valavu yowongolera kuthamanga kwakutali

Doko lakutali la valavu yothandizira limalumikizidwa ndi kulowa kwa valavu yakutali komwe kuli kosavuta kusintha, kuti azindikire cholinga chakutali.

5. Kuwongolera kwapamwamba ndi kotsika kwa masitepe ambiri

Gwiritsani ntchito valavu yobwerera kuti mugwirizane ndi doko loyang'anira kutali la valve yothandizira ndi malamulo angapo akutali kuti mukwaniritse kulamulira kwapamwamba ndi kotsika.

6. Amagwiritsidwa ntchito ngati valve yotsatizana

Doko lobwereranso lamafuta la valavu yoyendetsa ndegeyo limasinthidwa kukhala malo otulutsiramo mafuta otulutsa, ndipo njira yobwereranso mafuta imatsekeka pambuyo poti kukankhira kumatsegula valavu ya conical, kotero kuti doko lokonzedwanso la mafuta limatha. bwererani ku thanki, kuti igwiritsidwe ntchito ngati valavu yotsatizana.

7. Amagwiritsidwa ntchito popanga kukakamiza kumbuyo
Valve yothandizira imalumikizidwa motsatizana ndi kuzungulira kwamafuta obwerera kuti apange kupsinjika kwam'mbuyo ndikuwongolera kuyenda kwa actuator. Panthawiyi, kupanikizika kwa valve yotsitsimula kumakhala kochepa, ndipo valavu yochepetsera yotsika kwambiri imagwiritsidwa ntchito.
