Hydraulic balance valve Excavator hydraulic cylinder valve core RVEA-LAN

Mapangidwe oyambirira ndi mfundo yogwirira ntchito ya valve yothandizira Mu hydraulic transmission system, hydraulic valve yomwe imayang'anira kuchuluka kwa mphamvu ya mafuta imatchedwa valve control valve, yotchedwa valve pressure. Zomwe ma valvewa ali ofanana ndizomwe zimagwira ntchito pa mfundo yakuti kuthamanga kwamadzimadzi komwe kumagwira ntchito pa spool ndi mphamvu ya masika ndi yoyenera. Choyamba, kapangidwe kake ndi mfundo yogwirira ntchito ya valve yothandizira

Ntchito yaikulu ya valve yothandizira ndikupereka kupanikizika kosalekeza kapena chitetezo cha chitetezo cha hydraulic system.

(A) udindo ndi ntchito zofunikira za valve yothandizira

1. Udindo wa valve yothandizira mu hydraulic system kuti ukhalebe wopanikizika nthawi zonse ndi ntchito yaikulu ya valve yothandizira. Amagwiritsidwa ntchito nthawi zambiri pamakina owongolera liwiro, ndipo ma valve owongolera oyenda amagwiritsidwa ntchito kuti asinthe kayendedwe kake kachitidwe, ndikusunga kupanikizika kwa dongosolo nthawi zonse. Mavavu othandizira oteteza mochulukira nthawi zambiri amatchedwa ma valve oteteza.

2. Dongosolo la Hydraulic pazofunikira za magwiridwe antchito a valve

(1) Kulondola kwamphamvu kwambiri

(2) Kuzindikira kwambiri

(3) Ntchitoyo iyenera kukhala yosalala komanso yopanda kugwedezeka ndi phokoso

(4) Vavu ikatsekedwa, chisindikizocho chiyenera kukhala chabwino ndipo kutuluka kwake kukhale kochepa.

(2) Mapangidwe ndi mfundo yogwirira ntchito ya valve yothandizira

Valavu yothandiza yomwe imagwiritsidwa ntchito mosiyanasiyana malinga ndi kapangidwe kake ndi momwe amachitira zinthu imatha kuchepetsedwa kukhala mtundu wowongolera komanso woyendetsa wachiwiri.

1. Valavu yothandizira molunjika Chiwombankhanga chothandizira mwachindunji chimadalira mafuta opanikizika mu dongosolo kuti achitepo kanthu pa spool ndikuwongolera mphamvu ya masika kuti athetse kutsegula ndi kutseka kwa spool. Valve yothandizira imagwiritsa ntchito mphamvu yoyendetsedwa ngati chizindikiro kuti isinthe kuchuluka kwa kuponderezedwa kwa kasupe, motero kusintha malo othamanga a doko la valve ndi kuthamanga kwa kayendedwe ka kayendedwe kake kuti akwaniritse cholinga cha kupanikizika kosalekeza. Pamene kupanikizika kwa dongosolo kumakwera, spool imakwera, malo othamanga a doko la valve amawonjezeka, kuchuluka kwa kusefukira kumawonjezeka, ndipo kupanikizika kwa dongosolo kumachepa. Zotsatira zoyipa zomwe zimapangidwira ndi kusanja ndi kusuntha kwa spool mkati mwa valavu yothandizira ndi mfundo yofunika kwambiri ya kupanikizika kwake kosalekeza, komanso ndiyo mfundo yoyendetsera ntchito ya ma valve opanikizika nthawi zonse.
