Lub kaw lus hydraulic ntawm tag nrho hydraulic excavator muaj plaub yam tseem ceeb: cov khoom siv hluav taws xob, cov khoom ua haujlwm, cov khoom siv tswj thiab cov khoom siv pabcuam.
Cov khoom siv hluav taws xob feem ntau yog lub twj tso kua mis piston sib txawv, nws txoj haujlwm yog los hloov lub zog ntawm lub cav rau hauv lub zog ua kua, thiab qhov tshwm sim tsis zoo yog cov twj tso kua mis tsis txaus thiab txo qis.Yog tias qhov tshwm sim no maj mam, thiab qhov kub thiab txias yog qhov pom tseeb dua, nws yog vim kev hnav ntau dhau ntawm lub twj tso kua mis hydraulic;Yog tias qhov tshwm sim no tshwm sim tam sim ntawd, feem ntau yog vim lub plunger tsis ua haujlwm;Yog hais tias lub siab yog ib txwm, qhov ntws dheev txo qis, feem ntau tshwm sim los ntawm qhov sib txawv ntawm cov txheej txheem daig hauv qhov chaw me me.
Actuating cov ntsiab lus muaj xws li hydraulic thooj voos kheej kheej thiab hydraulic motors, nws txoj haujlwm yog los hloov lub siab ntawm cov kua rau hauv lub tshuab hluav taws xob, qhov tshwm sim tsis zoo yog qhov ua haujlwm qeeb lossis tsis ua haujlwm.Yog tias lub twj tso kua mis thiab lub valve tau lees paub tias tsis muaj qhov tsis raug, qhov laj thawj rau qhov ua haujlwm qeeb ntawm cov khoom siv hluav taws xob yog qhov tseeb vim nws hnav thiab tsim kua muag ntau dhau;Yog tias lub twj tso kua mis ua haujlwm ib txwm, qhov kev ua haujlwm qeeb ntawm cov khoom siv hluav taws xob yog qhov yuav tsum yog lub valve tswj cov khoom siv hluav taws xob muaj qhov ua txhaum, xws li lub valve tsis nyob hauv qhov chaw, lub valve tsis raug kaw kom nruj los yog lub caij nplooj ntoos hlav tsis muaj zog, thiab daim card.Vim tias qib hnav thiab tsim kua muag ntawm txhua tus thawj coj lub luag haujlwm yuav tsis txawv ntau, xws li lwm yam laj thawj, nws yuav tsum yog tus lej ntawm cov thawj coj ntawm qhov kev txiav txim tib lub sijhawm dheev ua qeeb qeeb;Yog tias nws paub tias lub twj tso kua mis thiab lub valve tsis ua txhaum, lub luag haujlwm tseem ceeb dheev tsis ua haujlwm, nws feem ntau yog vim nws sab hauv jamming.
Cov ntsiab lus tswj muaj xws li ntau yam li qub, xws li pilot li qub, ntau txoj kev taw qhia li qub, lub ntsiab kev nyab xeeb li qub, nyem li qub thiab ib-txoj kev throttle li qub, thiab lwm yam. , feem ntau daig, kaw thiab caij nplooj ntoos hlav elasticity tsis muaj zog thiab sab hauv thiab sab nraud to.
Cov khoom siv pabcuam feem ntau suav nrog cov roj tank, roj yeeb nkab, radiator, lim thiab accumulator, thiab lwm yam.. Cov haujlwm ntawm lub tshuab hluav taws xob yog los faib cov cua sov uas tsim los ntawm hydraulic system mus rau qhov chaw, thiab nws cov kev ua tsis zoo xws li roj to, tsis zoo cua sov dissipation, thiab lwm yam. Cov haujlwm ntawm cov lim dej yog lim cov impurities sib xyaw rau hauv cov roj hydraulic, thiab nws cov kev ua tsis tiav xws li clogging ntawm lub vijtsam.Lub luag haujlwm ntawm lub accumulator yog kom ruaj khov thiab tswj cov roj siab thiab khaws qee lub zog kom ntseeg tau tias kev ua haujlwm zoo thiab thaum lub cav tsis ua haujlwm, cov cuab yeej ua haujlwm tuaj yeem txo qis rau hauv av, thiab nws cov kev ua tsis zoo yog cov khoom siv tsis zoo. nyhuv, tsis tuaj yeem ua tiav cov haujlwm saum toj no.Cov khoom pabcuam ntawm qhov tsis ua haujlwm tshwm sim feem ntau pom tseeb, yooj yim rau kev kuaj mob.
