Hydraulic balance valve Excavator hydraulic cylinder valve core NFCD-LFN

Valve yothandizira njira zofala zothetsera mavuto

1) Doko lotulutsidwa la valve yothandizira oyendetsa ndege limatsekedwa ndipo silinatsekeredwe, ndipo mafuta olamulira alibe mphamvu, choncho dongosololi liribe mphamvu, ndipo doko lotulutsa liyenera kusindikizidwa bwino;

2) Dera lakutali lamafuta lolumikizidwa ndi doko loyang'anira kutali la valve yothandizira limatsegulidwa kuti liwongolere mafuta kubwerera ku thanki, kotero palibe kukakamiza mu dongosolo. Dera lamafuta akutali liyenera kuyang'aniridwa ndipo dera lamafuta lamafuta owongolera kubwerera ku tanki liyenera kutsekedwa;

3) Bowo lonyowa la valve yothandizira woyendetsa latsekedwa, zomwe zimapangitsa kuti pasakhale zovuta mu dongosolo. Bowo lotayirira liyenera kutsukidwa ndikusinthidwa mafuta;

4) Valovu yosowa ya cone kapena mpira wachitsulo kapena kuthamanga kowongolera masika ziyenera kusinthidwa munthawi yake;

5) Vavu yotayikira imayikidwa pamalo otseguka ndi dothi, ndipo iyenera kutsukidwa munthawi yake;

6) Pampu ya hydraulic palibe kukakamiza, iyenera kuthana ndi kulephera kwa pampu ya hydraulic;

7) Zigawo za dongosolo kapena kuwonongeka kwa mapaipi ndi kuchuluka kwa mafuta otayira, ziyenera kufufuzidwa munthawi yake kuti zikonzedwe kapena kusinthidwa.

3, kupanikizika kwadongosolo ndi kwakukulu kwambiri, kusinthako sikungatheke, kuyenera kuchitapo kanthu molingana ndi zifukwa zotsatirazi:

1) Dongosolo la mafuta olamulira kuchokera ku valavu yayikulu kupita ku valavu yoyendetsa ndege yatsekedwa, valavu yoyendetsa ndege sichiyendetsa kuthamanga kwa mafuta, fufuzani dera la mafuta kuti likhale logwirizana;

2) Doko lamkati la kukhetsa mafuta la valve yoyendetsa ndege limatsekedwa ndi dothi, ndipo valavu yoyendetsa ndegeyo silingathe kuwongolera kuthamanga. Doko lotulutsa mafuta mkati mwa valve yoyendetsa ndege liyenera kutsukidwa;

3) Kuvala kwa dzenje lonyowa kumakhala kwakukulu kwambiri, kuthamanga kwamafuta kumapeto onse a spool yayikulu, valavu yolowera singatsegulidwe, iyenera kukanikizidwa muzitsulo zosapanga dzimbiri monga dzenje lonyowa kapena waya wofewa wachitsulo woyikidwa. mu dzenje, kutsekereza mbali ya dzenje damping;

4) Kuipitsidwa kwamafuta, valavu ya slide imayikidwa pamalo otsekedwa.
