Kev tshuaj xyuas qhov cuam tshuam hydraulic tsis nyob rau hauv excavator systems

Muaj ob txoj hauv kev tswj xyuas tseem ceeb rau kev ua haujlwm ntawm lub twj tso kua mis loj ntawm cov hydraulic excavators: txwv load regulation (GLR) nrog rau kev txiav tawm siab (ie CUT-OFF muaj nuj nqi) thiab load sensing regulation (LS). Kev ua haujlwm ntawm CUT-OFF yog txhawm rau txo qis lub kaum sab xis ntawm lub twj tso kua mis hloov pauv hloov pauv thaum lub zog ua haujlwm siab mus txog qhov teeb tsa tus nqi, kom lub twj tso kua mis tsuas tuaj yeem tswj tau qhov "tseem tshuav" lub xeev uas yuav tsum tau ua kom muaj lub siab no, txhawm rau zam overheating tshwm sim los ntawm overflow ntawm lub nyem valve. Txhawm rau ua tiav lub hom phiaj no, cov txheej txheem tsis sib haum yog ua kom ntseeg tau tias qhov teeb tsa tus nqi ntawm CUT-OFF valve yog qis dua qhov teeb tsa tus nqi ntawm thawj lub siab valve hauv Circuit Court raws li kev xav tau; Txwv tsis pub, qhib thawj lub siab valve yuav ua rau overflow rau overheat.
Nyob rau tib lub sijhawm, xyuas seb lub valve thib ob puas ua haujlwm zoo. Qhov kev ua haujlwm no yuav tsum tau ua nruj me ntsis raws li cov kev cai, thiab yog tias tsim nyog, kev hloov kho yuav tsum tau ua rau cov txheej txheem tsis sib xws.
