Zida zokumba E200B E320B valavu yothandizira mfuti yothandizira hydraulic valve 352-7122

Valavu yaikulu yothandizira imayikidwa pamwamba ndi m'munsi mwa valavu yaikulu yolamulira, imodzi pamwamba ndi pansi. Valavu imayika kupanikizika kwakukulu kwa hydraulic system yonse kuti igwire ntchito. Pamene kupanikizika kwa dongosolo kumadutsa kupanikizika kwa valve yaikulu yothandizira, valavu yaikulu yothandizira imatsegula kayendedwe ka mafuta a thanki yobwereranso kuti iwononge mafuta a hydraulic kubwerera ku thanki kuti ateteze dongosolo lonse la hydraulic ndikupewa kuthamanga kwa mafuta kwambiri. Valve yothandizira ili ndi magulu awiri othamanga, pamene kuthamanga kwa woyendetsa ndege KUTHA, chifukwa choyamba cha 355kg / cm2; Pamene kuthamanga kwa woyendetsa kuli ON, ikani kuthamanga kwa 380kg/cm2 pa gawo lachiwiri.

Kuzindikira zolakwika

Chochitika cholakwika: Liwiro la zida zonse zogwirira ntchito ndi pang'onopang'ono (liwiro la zida zonse zogwirira ntchito ndi lotsika kuposa mtengo wanthawi zonse), ntchitoyo ndi yofooka, kupanikizika kwakukulu kwa pampu yayikulu ndi yochepera 150kg / cm2.
Chotsatira choyendera: Chopulizira chachikulu cha valve (3) chili ndi dothi lomwe limatsekereza dzenje la φ0.5.

Kusanthula zolakwika: Chifukwa cha pulagi ya plunger (3) dzenje, kusiyana kwapakati pakati pa mbali ziwiri za pulayi (3) ndi yaikulu kwambiri, plunger (3) nthawi zambiri imakhala yotseguka, ndipo mafuta othamanga kwambiri amadutsa pa plunger. (3) thanki yamafuta wamba, kotero kuthamanga kwakukulu kumachepetsedwa.

Kuthetsa mavuto: 1) phatikizani ndikuyeretsa valavu musanayiphatikize.

2) Yang'anani kuti mafuta a hydraulic ndi fyuluta sichinasinthidwe kwa nthawi yayitali, ndi yonyansa kwambiri, zonyansa zomwe zimatsekereza mabowo zimachokera ku mafuta a hydraulic, choncho yeretsani payipi, m'malo mwa mafuta a hydraulic ndi fyuluta.

3) Yesaninso zonse zitatha, ndipo kupanikizika kudzabwerera mwakale.
