Hydraulic tshuav valve Excavator hydraulic lub tog raj kheej valve tub ntxhais RDDA-LEN

Ua ntej, vim li cas peb thiaj li xav tau kev tsav tsheb pab li qub?
1, raws li lub zog ruaj khov siab nyem valve muaj nuj nqi, vim qhov ncaj qha nyem nyem valve qhib thiab kaw cov yam ntxwv (cov yam ntxwv siab ntws) yog qhov tsis zoo, tshwj xeeb tshaj yog thaum cov dej ntws loj, yog li thawj qhov laj thawj yog hloov mus rau qhov nce. ntawm flow specifications; Qhov zoo yog qhov ruaj khov siab, zoo qhib thiab kaw cov yam ntxwv, me me siab poob, thiab lwm yam. Qhov cuam tshuam zoo yog tias qhov nrawm ntawm qhov kev txiav txim siab phem dua li hom kev txiav txim ncaj qha, uas tsis haum rau kev siv raws li kev ruaj ntseg valve;
2, txhawm rau pab txhawb kev ua tiav ntawm kev tshem tawm hluav taws xob, kev tswj ntau theem siab, tswj chaw taws teeb thiab lwm yam haujlwm;
Thib ob, kev ua haujlwm ntawm kev ua haujlwm ncaj qha nyem valve
1, direct acting nyem valve feem ntau suav hais tias tsuas yog tsim nyog rau qhov tsis tshua muaj siab thiab ntws me me. Haum rau me me ntws yog txoj cai, tsis tshua muaj kev cuam tshuam tsis tas yuav tsum tau, lub luag haujlwm tseem ceeb ntawm kev kub siab pilot nyem valve yog ncaj qha ua haujlwm nyem valve;
2, qhov ncaj qha nyem valve feem ntau tsuas yog suav tias yog theem pib ntawm kev tsav lub siab valve (relief valve, sequence valve, siab txo valve, thiab lwm yam), tsis them sai sai rau nws yog cov qauv nyiam ntawm kev ceev ceev- acting kev ruaj ntseg valve, qhov tseeb, kev nyab xeeb valve ntawm qee yam khoom siv tseem ceeb, qhov ntws loj heev! Ntawm no yog qhov tseem ceeb ntawm kev ceev nrawm, hauv paus tsis xav txog qhov qhib thiab kaw cov yam ntxwv, tus yuam sij yog kom muaj kev nyab xeeb!
