SUN CBDGCJN Pilot Ratio Restrictive Counterbalance Hydraulic Valve
Khoom Specification
CBDGCJN raws li qhov sib npaug li qub nrog kev pab tsav dav hlau yog txhais tau tias tswj tau lub nra hnyav dhau. Lub check valve pub dawb ntws los ntawm lub directional valve (chaw nres nkoj 2) mus rau lub load (chaw nres nkoj 1) thaum lub direct-acting, pilot-pab nyem valve tswj ntws los ntawm qhov chaw nres nkoj 1 mus rau qhov chaw nres nkoj 2. Pilot pab ntawm qhov chaw nres nkoj 3 txo qhov chaw zoo. ntawm lub valve nyem ntawm tus nqi txiav txim los ntawm tus tsav piv.
Lwm lub npe rau lub valve no suav nrog lub zog tswj valve thiab tshaj-center valve.
Counterbalance li qub yuav tsum tau teem tsawg kawg yog 1.3 npaug ntawm qhov siab tshaj plaws load induced siab.
Cov kev txwv tsis pub muaj tsis muaj peev xwm pab tau lwm yam tshaj li thermal nyem.
Tig kev hloov kho clockwise kom txo qhov chaw thiab tso tawm load.
Kev teeb tsa tag nrho ntawm lub moos yog tsawg dua 200 psi (14 bar).
Backpressure ntawm qhov chaw nres nkoj 2 ntxiv rau qhov kev daws teeb meem zoo ntawm qhov sib piv ntawm 1 ntxiv rau qhov piv txwv piv rau qhov backpressure.
Reseat tshaj 85% ntawm kev teeb tsa siab thaum lub valve yog txheej txheem teeb tsa. Kev teeb tsa qis dua tus qauv teeb tsa siab tuaj yeem ua rau qis dua qhov feem pua reseat.
Sun counterbalance cartridges tuaj yeem ntsia tau ncaj qha rau hauv kab noj hniav hauv lub tsev actuator rau kev tiv thaiv ntxiv thiab txhim kho qhov nruj hauv Circuit Court.
Ob daim tshev valve cracking pressures muaj. Siv 25 psi (1,7 bar) kos tshwj tsis yog tias tus actuator cavitation yog ib qho kev txhawj xeeb.
Lub valve no muaj cov ntsaws ruaj ruaj zoo ntawm txhua qhov chaw nres nkoj.
Tag nrho 3-chaw nres nkoj counterbalance, load tswj, thiab pilot-to-open check cartridges yog lub cev sib hloov (piv txwv li tib txoj kev ntws, tib kab noj hniav rau ib tug ncej loj).
Koom nrog lub hnub ntab style kev tsim kho kom txo tau qhov muaj peev xwm ntawm cov khoom siv sab hauv khi vim kev teeb tsa ntau dhau torque thiab / lossis kab noj hniav / cartridge machining variations.
