Sib npaug Valve Pilot Ua Haujlwm Pab Dawb Cbba-Lhn

Tsheb Crane yog siv dav, muaj ntau lub hom phiaj tsheb, nrov hauv kev ua haujlwm ntawm lub tsheb tshwj xeeb, los ntawm kev sib txuas, los ntawm kev sib xyaw ua ke kom ua tiav kev ua haujlwm lifting. Muaj ib feem sib npaug valve nyob rau hauv cov kab ke hydraulic thiab ua tau cov khoom siv hnyav, thiab ua kom cov caj npab hnyav, thiab ua kom cov caj npab uas ruaj khov nyob rau hauv ib qho chaw nyob hauv qhov chaw.
Kev Ntsuas Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob Hauv Lub Ntiaj Teb uas tau siv cov roj ntsha uas muaj qhov sib luag, txhawm rau txhawm rau txhawm rau kom muaj kev sib tw ntawm lub pob hluav taws xob ruaj khov, txhawm rau txhawm rau txuag cov nqi, kom txuag tau cov nqi, txhawm rau txhawm rau txhawm rau hauv lub valve TW kev swb valve yog siv los hloov qhov sib npaug valve. Qhov no yog vim hais tias qhov sib npaug valve kuj yog kev sib txuas ntawm ib-txheej valve tau ntxiv ib ob chav ua ntu zus thiab lwm cov khoom siv kom ua rau lub valve core shourpe abrorber; Qhov thib ob yog tias tswj cov roj ncig ntawm lub valve sib npaug yuav tsum txuas nrog lub voj voog uas muaj "sluggish", thiab nws txoj kev nrawm nrawm tsis hloov pauv me me ntawm cov kev hloov pauv me me.
