Hydraulic ntaus ntawv yog ib tug tsav tsheb uas siv hydraulic siab qhib thiab kaw los yog kho li qub. Nws muaj peb ntu: tswj, fais fab thiab actuator. Cov kev tswj xyuas muaj xws li kev tswj lub siab valve, ntws tswj valve, kev taw qhia tswj valve, thiab lwm yam thiab hluav taws xob tswj system. Lub tshuab hluav taws xob muaj lub tshuab hluav taws xob lossis lub tshuab pneumatic, lub twj tso kua mis hydraulic, roj tank thiab lwm qhov chaw, uas hloov lub zog zoo ntawm lub rotating ncej ntawm hluav taws xob los yog pneumatic lub cev muaj zog rau hauv cov dej siab zog ntawm hydraulic kis tau tus mob. Muaj ob hom actuators, ib qho yog hydraulic lub tog raj kheej actuator, uas paub txog reciprocating linear motion; Lwm qhov yog hydraulic lub cev muaj zog actuator, uas paub txog cov lus tsa suab. Qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hydraulic yog raws li hauv qab no:
(I) Qhov zoo ntawm cov khoom siv hydraulic valve
1. Yooj yim, compact qauv thiab me me;
2. Kev sib kis tau yooj yim thiab txhim khu kev qha;
3. Lub zog loj tso zis tuaj yeem tau txais;
4. Cov zis torque tuaj yeem raug kho kom raug los ntawm qhov tsis tu ncua lub siab nyem valve, suav nrog kev hloov kho ntawm qhov qhib thiab kaw lub zog, thiab tuaj yeem cuam tshuam ncaj qha los ntawm cov twj hydraulic;
5. Kev hloov ceev yooj yim;
6. Thaum lub hwj chim tam sim ntawd cuam tshuam vim muaj kev sib tsoo, lub accumulator tseem tuaj yeem siv rau ib lossis ntau lub zog ua haujlwm. Qhov no yog qhov tseem ceeb tshwj xeeb rau qhov tsis siv neeg kaw thaum muaj xwm txheej ceev thiab lub taub hau blowdown valve ntawm cov kav dej ntev.
(II) Qhov tsis zoo ntawm cov khoom siv hydraulic valve
1. Cov roj kub muaj kev cuam tshuam zoo heev los ntawm qhov kub thiab txias. Kev hloov ntawm cov roj kub ua rau cov viscosity ntawm cov roj hloov, cuam tshuam rau kev ua haujlwm;
2. Cov kav dej yog qhov teeb meem thiab muaj feem cuam tshuam;
3. Nws tsis haum rau ntau yam haujlwm ntawm lub teeb liab (xws li teeb liab amplification, nco, kev txiav txim siab, thiab lwm yam)
