Amavalvu Amafutha - YHF, RV Hydraulic Valve

I-HF/RV hydraulic hydraulic directional control valve isetshenziselwa iphampu kagesi yohlobo lwendandatho emaphakathi ohlelweni lokuthambisa, Iphampu yokugcoba ye-DRB-L okukhipha amafutha ngokushintshana bese ehambisa igrisi noma uwoyela emapayipini amabili amakhulu ahlinzekayo, ishintsha ngokuqondile i-spool ye-HF/RV hydraulic hydraulic directional control valve ngengcindezi evela epayipini elikhulu. Ukucindezela okusethiwe kwesiqondiso se-hydraulic kuvunyelwe ukulungiswa kalula, isakhiwo se-valve ye-HF / RV silula, ukusebenza okuthembekile okusebenzayo.

I-HF/RV Hydraulic Directional Control Valve Principle:
– Ichweba le-T1, T2, T3, T 4 lixhuma endaweni efanayo kudivayisi yokugcina uwoyela.
- Igrisi noma uwoyela ophuma endaweni yoku-1 futha ifakwa embotsheni yokungena engu-S ngevalvu eyinhloko ye-spool MP ukuya epayipini likagrisi/likawoyela L1 (umugqa wepayipi I) kanye nokucindezela kokudlula kwevalve yesilayidi somshayeli Pp kusetshenziswa i-spool enkulu kwesokunxele ekamelweni. Ipayipi likawoyela i-L2 livulelwa ithangi likawoyela ngembobo ye-T1.
– Ukuphela kwepayipi lokuhambisa uwoyela i-L1 lixhunywe embotsheni yokubuya engu-R1, futhi lapho ingcindezi ekugcineni idlula ingcindezi yokusetha ngaphambilini, i-spool yomshayeli iphushelwa ekamelweni elifanele.
- I-valve yesilayidi ye-Pilot ye-Position 2 i-Pp iya kwesokudla, uhlangothi lwesobunxele lwe-spool valve Mp ivulelwa endaweni yokugcina uwoyela ngembobo ye-T3, amafutha okukhipha iphampu icindezelwa ekugcineni kwesokudla kwe-spool valve enkulu, iphushelwe ukuze ohlangothini lwesobunxele. Othintwayo ku-lever yenkomba ye-spool valve ushaya i-stroke switch LS futhi athumele isignali kukhabhinethi yokulawula ukuze kumiswe iphampu.
- Isikhundla se-3 main slide valve Mp ihanjiswe kwesokunxele, ukuze kuqedelwe isenzo sokushintshwa kokuqondisa, i-grease ephumayo yepompo futhi nge-valve yesilayidi eyinhloko ithunyelwa epayipini elikhulu lokuhlinzeka nge-L2 (ipayipi Ⅱ), ipayipi likawoyela L1 kugrisi/ indawo yokugcina uwoyela ngokusebenzisa ichweba le-T2.

Ukusetshenziswa kwe-HF/RV Hydraulic Directional Control Valve:
- I-valve ye-YHF-L1 ifakwe ku- Iphampu yokugcoba ye-DRB-L ngesilinganiso sokugeleza esingu-585 mL/min futhi sifakwe ku-base plate. Ivalvu – YHF-L2 ifakwe kumaphampu okugcoba e-DRB-L anezilinganiso zokugeleza okungu-60 no-195 mL/min.
-YHF-L1-uhlobo lokulungiswa kwe-valve screw dextral yokwandisa ingcindezi, kwesokunxele yehlisa ingcindezi. I-valve yohlobo lwe-YHF-L2-i-valve yesandla sokudla ibeka phansi, ikhuphuka kwesokunxele.
– Lapho ukhipha i-valve ye-YHL-L2 empompini yokugcoba ye-DRB-L futhi ukhipha isembozo se-valve ye-YHF-L1, usetha ukukhululwa kwesikulufu sokulungisa ngokuphelele.
