Izesekeli ze-Excavator E200b e320B ZOKULULA I-VALULE I-HUND HYDRAULIC Valve 352-7122

I-valve enkulu yokusiza ifakiwe emaphethelweni aphezulu nangaphansi we-valve yokulawula eyinhloko, eyodwa ephezulu neyodwa ephansi. I-valve isetha ingcindezi ephezulu yohlelo lonke lwe-hydraulic ukusebenza. Lapho ingcindezi yesistimu idlula ingcindezi ebekiwe ye-valve yosizo olukhulu, i-valve yokukhululeka ivula umjikelezo kawoyela wethangi lokubuya ukuze lichichime uwoyela we-hydraulic emuva ethangini ukuze uvikele lonke uhlelo lwe-hydraulic futhi uvikele ukucindezela kwamafutha ngokweqile. I-valve yokusiza inamasethi amabili wengcindezi, lapho ingcindezi yokushayela icishiwe, ngokucindezela kokuqala kwengcindezi ye-355kg / cm2; Lapho ukucindezela komshayeli kuvuliwe, setha ingcindezi 380kg / cm2 yesigaba sesibili.

Ukuxilongwa kwamaphutha

I-Fault Phenomenon: Ijubane lawo wonke amadivaysi okusebenza lihamba kancane (ijubane lawo wonke amadivaysi okusebenza liphansi kunenani elijwayelekile), umsebenzi ubuthakathaka, ukucindezela okukhulu kwephampu enkulu kungaphansi kwe-150kg / cm2.
Umphumela wokuhlola: I-Plunger enkulu yokusiza (3) inokubhuka okuvimba i-φ0.5 Hole.

Ukuhlaziywa kwe-Fault: Ngenxa yepulaki ye-Plunger (3) Hole, umehluko wokucindezela phakathi kwamaphethelo amabili we-plunger (3) mkhulu kakhulu, futhi i-plunger (3) ithangi eliphakeme le-oyili, ngakho-ke ingcindezi enkulu iyancipha.

Ukuxazulula inkinga: 1) Hlukanisa futhi uhlanze i-valve ngaphambi kokuhlangana.

2) Bheka i-hydraulic oil kanye nento yokuhlunga akushintshi isikhathi eside, kungcolile kakhulu, ukungcola okuvinjelwe izimbobo kuvela kumafutha e-hydraulic, ngakho-ke hlanza ipayipi, esikhundleni se-hydraulic oil kanye nento yokuhlunga.

3) Zama futhi ngemuva kokuqedwa konke, futhi ingcindezi izobuyela kokujwayelekile.
