Lub hydraulic servo system enables cov zis ntawm lub system, xws li hloov chaw, ceev los yog quab yuam, hloov tau, sai thiab raug raws li qhov kev hloov ntawm cov tswv yim, thiab nyob rau tib lub sij hawm, lub zog tso zis ntau amplified. Hydraulic servo system tau siv dav hauv kev tswj hwm kev lag luam vim nws qhov tshwj xeeb zoo xws li cov lus teb ceev ceev, loj load rigidity, thiab loj tswj fais fab.tsis siv neeg cement cib ua tshuab, lub tshuab hluav taws xob-hydraulic servo siv electro-hydraulic servo li qub los hloov cov hluav taws xob qis hluav taws xob rau hauv high-power hydraulic zog, yog li paub txog servo tswj.
Lub hydraulic kis tau tus mob muaj ib tug hydraulic tsis siv neeg tswj system rau kev soj ntsuam xyuas. Hauv cov txheej txheem no, cov khoom siv hluav taws xob siab siab (xws li hydraulic servo li qub thiab hydraulic actuators) ua raws li cov kev ua ntawm cov teeb liab hluav taws xob qis. Cov actuators feem ntau tswj cov khoom siv ntau yam xws li txoj haujlwm thiab ceev. Cov teeb liab hais kom ua kuj tseem hu ua cov teeb liab siv hluav taws xob, uas xa tawm cov teeb liab hais kom sawv cev rau txoj haujlwm, ceev lossis lwm qhov ntau. Qhov piv ntawm lub zog siab rau qis zog tuaj yeem ncav cuag ntau lab lub sijhawm. Hydraulic servo system yog lub tswv yim tswj qhov system. Cov teeb liab tawm tswv yim uas sawv cev rau lub xeev tiag yog piv nrog cov teeb liab hais kom tau qhov teeb meem yuam kev. Yog tias qhov yuam kev tsis yog xoom, nws raug kho.
Lub kaw lus hydraulic servo yuav tsum feem ntau suav nrog: cov ntsiab lus ntsuas lub xeev qhov tseeb; low-power command signal kis tau tus mob thiab high-power hydraulic actuator Cheebtsam; xav tau lub xeev thiab tawm tswv yim lub xeev kev sib piv Cheebtsam; sib txawv teeb liab amplification Cheebtsam. Hydraulic servo system muab faib ua mechanical hydraulic servo system, electro-hydraulic servo system thiab roj-hydraulic servo system. Lawv cov teeb liab hais kom ua yog cov khoom siv hluav taws xob, cov teeb liab hluav taws xob thiab cov paib cua siab. Electro-hydraulic servo system yog dav siv vim nws hloov tau hluav taws xob tswj; gas-kua servo system yog siv nyob rau hauv tawg-pov thawj ib puag ncig los yog lub sij hawm uas nws yog ib qho yooj yim kom tau txais huab cua siab teeb liab. Lub hydraulic servo system yuav tsum muaj qhov tsim nyog ua haujlwm: kev ua haujlwm ruaj khov; cov lus teb ceev rau cov lus txib; me me tsis tu ncua-lub xeev yuam kev; insensitive rau kev cuam tshuam. Lub tshuab hydraulic servo yog qhov siv dav tshaj plaws hauv kev tswj tsis siv neeg. Nyob rau hauv lub precision machining positioning system, hydraulic servo system tuaj yeem lav machining yuam kev tsawg dua 0.1 micron.
