Raws li lub hauv paus ntsiab lus ntawm cov kua dej sib npaug thiab qhov sib npaug ntawm qhov sib npaug, qhov loj yog ntsuas los ntawm cov cuab yeej ntawm cov kua siab hloov pauv. Hydraulic txoj cai nyob rau hauv ib tug tej yam txhua yam, hluav taws xob system, cia siab rau qhov zoo li qub siab ntawm cov kua nruab nrab, ua kom tiav lub zog backlog, kis tau tus mob, amplification, ua kom tiav cov neeg kho tshuab muaj nuj nqi ntawm lub teeb yuag, scientific, maximize. Siv lub hauv paus ntsiab lus hydraulic, koj tuaj yeem tsim lub tshuab xa hluav taws xob hydraulic, koj tuaj yeem tsim lub tshuab tswj hydraulic. Lub hauv paus muaj nuj nqi ntawm hydraulic Circuit Court yog qhov yooj yim tswj lub zog hloov mus rau hauv daim ntawv ntawm cov kua siab zog.
Kev siv thiab kev saib xyuas cov tshuab hydraulic yog nyob ntawm kev nkag siab zoo ntawm cov yam ntxwv ntawm cov dej thiab kev ua haujlwm ntawm cov khoom siv tshuab. Txhawm rau ua haujlwm thiab tswj hwm lub tshuab hydraulic, cov neeg ua haujlwm hauv thaj chaw yuav tsum muaj qee qhov kev paub txog lub zog ntawm cov kua dej, tab sis kuj yuav tsum paub txog xya yam tseem ceeb uas ua rau lub tshuab hydraulic. Ntau lub tshuab hydraulic zoo li nyuaj heev, tab sis qhov tseeb, lawv cov qauv tsim qauv yooj yim heev.
Tsis muaj teeb meem npaum li cas lub hydraulic system yog, txhua qhov system yog tsim los ntawm xya lub hauv paus Cheebtsam:
1, roj tank;
2, cov kav dej siv los xa cov kua hluav taws xob;
3. Hydraulic twj tso kua mis uas hloov lub zog input mus rau hauv lub zog dej;
4. Siab tswj valve rau kev tswj lub siab;
5, tswj cov kev taw qhia ntawm cov kua dej ntws tswj valve; 6, cov khoom siv tswj kev ntws los kho qhov nrawm lossis ntws;
7. Lub actuator uas converts hydraulic zog rau txhua yam zog.
Los ntawm qhov kev xav ntawm lub zog hloov pauv: hydraulic thev naus laus zis yog kwv yees nyob rau hauv nruab nrab ntawm kev hloov pauv hluav taws xob thiab hluav taws xob hloov hluav taws xob. Los ntawm qhov kev xav ntawm cov yam ntxwv kis tau tus mob: mechanical kis tau tus mob thiab hydraulic kis tau tus mob tuaj yeem hais tias muaj cov yam ntxwv ruaj khov, ntawm qhov tsis sib xws, hydraulic kis tau tus mob thiab cov khoom siv hluav taws xob sib txuas yog tib yam, nrog rau cov yam ntxwv ntawm cov khoom siv tsis tu ncua, ntxiv rau lub zog tas li, tab sis kuj yooj yim kom ua tiav qhov nrawm thiab tsis tu ncua torque thiab lwm yam ntxwv.
Cov yam ntxwv ntawm hydraulic tshuab feem ntau tuaj yeem sau tau raws li hauv qab no:
(1) Nws yog ib qho yooj yim mus nqa tawm stepless kis tau tus mob, thiab kis tau tus mob ntau yam, uas yog, lub zog thiab torque yuav tau yooj yim kho nyob rau hauv ntau yam;
(2) Kev tswj hwm kev ua tau zoo, uas yog, quab yuam, nrawm, txoj haujlwm, thiab lwm yam, tuaj yeem tswj tau kom raug nrog lub siab teb ceev. Tsis tas li ntawd, nws muaj kev hloov tau zoo rau hluav taws xob, kev siv tshuab thiab lwm yam kev tswj hwm, tshwj xeeb tshaj yog thaum ua ke nrog cov teeb liab hluav taws xob ua, cov yam ntxwv zoo heev tuaj yeem tau txais.
(3) txhim khu kev qha kev ua haujlwm, kev ua haujlwm zoo;
(4) hloov tau yooj yim hauv cov qauv thiab cov yam ntxwv;
(5) Ib lub voj voog tuaj yeem tsim nrog cov qauv tsim kom ua tiav cov haujlwm tsis sib haum xeeb. Yog vim li cas rau qhov tsim ntawm cov yam ntxwv no yog hais tias qhov zoo ntawm cov khoom hloov pauv yog siv los ua lub peev xwm hloov, uas yog, lub twj tso kua mis hydraulic thiab hydraulic actuator, thiab cov roj lubricating (cov roj hydraulic) yog siv los ua haujlwm nruab nrab. Qhov tsis zoo ntawm cov tshuab hydraulic kuj tseem cuam tshuam nrog cov kua dej hydraulic.
Cov shortcomings tau sau tseg raws li nram no:
(1) roj to;
(2) Nyob rau hauv rooj plaub uas yuav tsum tau tswj tshwj xeeb precision, cov pa phem ntawm cov roj hydraulic muaj kev cuam tshuam tsis zoo rau cov yam ntxwv ntawm cov khoom thiab cov khoom siv. Qhov ntawd yog hais tias, kev tswj hwm ntawm cov kua dej hydraulic muaj qhov cuam tshuam zoo rau kev ntseeg siab thiab kev tiv thaiv lub neej. Lub hauv paus ntsiab lus ua hauj lwm ntawm hydraulic kis tau tus mob yog raws li PASCAL lub hauv paus ntsiab lus ntawm engineering fluid mechanics, uas hloov lub zog los ntawm lub siab ntawm cov kua. Cov yam ntxwv ntawm hydraulic tshuab yog tsim rau ntau yam tshuab thiab khoom siv automation, kev ua haujlwm siab, muaj peev xwm loj, me me, lub teeb yuag thiab lwm yam yuav tsum tau ua. Yog li ntawd, txawm hais tias nws yog ib ceg tshiab ntawm cov thev naus laus zis, nws tau siv dav hauv kev sib kis ntawm lub cev muaj zog, kev ua haujlwm ntawm cov cuab yeej pabcuam lossis kev ua haujlwm automation tswj mechanism.
Qhov zoo thiab qhov tsis zoo ntawm kev tshaj tawm kho qhov zoo
1, ntau yam ntawm hydraulic kis tau tus mob tuaj yeem yooj yim thiab yoog raws li kev xav tau.
2, lub teeb yuag, me me, me me zog inertia, ceev cov tshuaj tiv thaiv ceev.
3, yooj yim rau kev khiav lag luam thiab tswj, tuaj yeem ua tiav ntau yam kev tswj tsis tau nrawm.
4, tuaj yeem paub txog kev tiv thaiv overload.
5, feem ntau siv cov roj ntxhia los ua qhov nruab nrab ua haujlwm, tus txheeb ze txav chaw tuaj yeem ua tus kheej lubricating, lub neej ua haujlwm ntev.
6, yooj yim mus cuag linear zog.
7, nws yog ib qho yooj yim mus cuag lub automation ntawm lub tshuab, thaum siv electro-hydraulic ob leeg tswj, tsis tsuas yog muaj peev xwm ua tau ib tug ntau dua degree ntawm tsis siv neeg tswj txheej txheem, tab sis kuj muaj peev xwm ua tau tej thaj chaw deb tswj.
1, vim qhov tsis kam thiab cov kua dej ntws tawm, yog li kev ua haujlwm tsawg. Yog tias tsis kho kom raug, cov dej xau tsis yog tsuas yog kis mus rau qhov chaw, tab sis kuj tseem tuaj yeem ua rau hluav taws kub thiab tawg.
2, vim hais tias kev ua haujlwm ua haujlwm raug cuam tshuam rau qhov kub thiab txias, nws tsis haum rau kev ua haujlwm nyob rau hauv qhov kub thiab txias heev.
3, kev tsim khoom raug ntawm cov khoom siv hydraulic yog siab dua, yog li tus nqi kim dua.
4. Vim yog qhov to thiab compressibility ntawm cov kua nruab nrab, qhov kev sib kis nruj tsis tuaj yeem tau txais.
5, hydraulic kis tsis ua haujlwm tsis yooj yim kom paub qhov laj thawj; Kev siv thiab kev saib xyuas yuav tsum muaj kev siv tshuab siab.
