I-PC200-6 PC300-6 ivalvu eyinhloko yokusiza isibhamu 708-2L-04312

I-valve yokusiza yama-hydraulic excavators inemisebenzi emine eyinhloko:

1, kuhlelo lwephampu yomthamo (iphampu yegiya) olusetshenziswa ukugeleza uwoyela oweqile ubuyela ethangini ukuze kugcinwe ingcindezi yesistimu ye-hydraulic (icishe ibe njalo).

I-2, ohlelweni oluguquguqukayo lwephampu ye-hydraulic, kuphela lapho ingcindezi idlula inani lokucindezela osethiwe, ukuchichima kuyavulwa, ukuze ukucindezela kwesistimu kungasakhushulwa, futhi indima yokuvikela ukuphepha ngokuvamile ibizwa ngokuthi i-valve yokusiza.

I-3, ohlelweni, esetshenziselwa ukuvikela i-actuator (njengesilinda) noma izingxenye zesakhiwo ngaphansi kwesenzo samandla angaphandle aqinile awonakali, kulokhu, i-valve yokusiza, siyibiza ngokuthi i-valve yokulayisha ngokweqile.

4, njenge-valve yokunciphisa ingcindezi, indlela ejikelezayo yokunciphisa, ukunciphisa ingcindezi.

Isimiso sokusebenza se-valve yokusiza

1. I-Pump pressure PP iyakhuphuka

2, ngaphezu kuka-21.6MP

3, ingcindezi yepompo ukusunduza ikhanda eliphakamisayo ukuze linqobe amandla asentwasahlobo ukuze liqhubekele phezulu

4. Imbobo encane ku-plunger (kuphela i-0.5) iqala ukugeleza kwamafutha

5. I-plunger iphushelwa phezulu ngenxa yomehluko wengcindezi phakathi kwengaphambili nangemuva (iphansi likhulu futhi elingaphezulu lincane)

6, amafutha okucindezela abuyele ethangini

7, ingcindezi yephampu yehla kuze kube ngu-21.6
