Yuav ua li cas yog hydraulics? Txhais lub tswvyim

Hydraulic machinery mus rau lub hiob system siv nyob rau hauv lub tswv yim engineering. Los ntawm nws tus kheej, lub hauv paus ntsiab lus ntawm mechanized txiav txim maj loses nws qhov tseeb raws li nws squeezed ntau sophisticated tsav tsheb txhais tau tias. Tab sis vim hais tias ntawm lub tsawg possibilities ntawm integrating tshiab thiab kim kim kev daws teeb meem nyob rau hauv ntau qhov chaw koom tes nws txoj hauj lwm thiab cov tsoos mechanics. Yuav ua li cas yog lub hydraulics kev khiav hauj lwm nyob rau hauv ib tug niaj hnub ntsiab lus teb? Qhov no infrastructure, uas yog muab kev koom tes nyob rau hauv cov tshuab, lug thiab vaj tse, muab txaus quab yuam kom actuate haumxeeb chav nyob thiab cov rooj sib txoos.

Cov yooj yim txhais ntawm hydraulics

Ntawm tus taw tes ntawm view ntawm science, hydraulics - ib tug seem ntawm kev txawj ntse, yuav tsum vov lub cai ntawm cov lus tsa suab thiab equilibrium ntawm cev. Lub aqueous nrab nyob rau hauv ib daim ntawv los yog lwm yog ib tug loj nam ntawm txoj kev tshawb nyob rau hauv no cov kev taw qhia. Nyob rau hauv tas li ntawd mus theoretical kev tshawb fawb thiab kev sim zaum muab kev koom tes nyob rau hauv cov kev ntsuam xyuas, kev soj ntsuam uas ua lub hauv paus rau kev daws ntawm cov teeb meem ntawm muaj ntaub ntawv engineering. Kev ua hauj lwm mob siab rau rau cov kev cai ntawm cov dej zog los ntawm lub raj dej raws, dej txaj thiab hydraulic machine. Tab sis rau ib tug tag nrho cov kev nkag siab txog dab tsi lub hydraulics nyob rau hauv ib tug scientific ntsiab lus teb, peb yuav tsis ua yam uas tsis muaj hais txog kev kawm, cuab yeej uas yog nyob rau hauv txoj kev tshawb no. Cov no muaj xws physics, lej thiab mechanics. ob qhia hydraulic cov kev tshawb fawb kuj tseem ceeb - zoo li qub thiab dynamic ntsiab lus. Hydrodynamics seb puas tsimnyog tau cov lus nug ntawm kinematics ntawm cov dej xws li, tab sis ntau oriented rau hydrostatic cai ntawm kev sis raug zoo ntawm cov kua nrog lwm kua thiab khib nyiab.

hydraulics Engineering

Tseem hu ua qhov kev kawm ntawm hydraulics seem tsis yog raws li ntau nyob rau hauv kev sib piv nrog nws derivatives nyob rau hauv lub tswv yim tus kheej. Cov tib applied paub raws li systems engineering tej yaam num - piv txwv li, ib tug ntawm cov hiob khoom ntawm hydraulics yog tus ciav dej. Niaj hnub no, cov kev cai ntawm lub zog kua yog lub hauv paus rau txoj kev loj hlob ntawm phwj systems, reciprocating khoom, cov dej thiab thiaj li nyob. D.

Nyob rau hauv feem ntau hom hauj lwm hydraulic ncaav raws li tsav tsheb quab yuam rau tsav cov chav nyob serviced. Ib tug classic piv txwv yog lub hydraulic tshuab. Nyob rau hauv kev peb yuav deduce no txhais ntawm engineering hydraulics - ib tug txheej ntawm cov neeg kho tshuab siv hais, uas ntaus ntawv yuav siv cov kua li ib tug active ib puag ncig. Tab sis qhov no tsis txhais hais tias cov dej yog lub hauv paus ntawm kev quab yuam. Nws tsuas zog tshuab txhais lus hais tias nws yog txuas mus rau lwm cov mechanisms, uas, nyob rau hauv lem, tshuab txais los ntawm hluav taws xob motors thiab hwj chim rau lwm rau ib tug kua los yog khoom-roj.

Hom ntawm hydraulic configurations

Ua hauj lwm hydraulic tshuab voj voog nyob rau hauv Circuit Court los ntawm kev uas dej yeej. Qhov no contour yog precisely txiav txim rau lub sij hawm ntawm lub lag luam dej, thaum lub sij hawm uas nws acquires hwj chim ntawm lub engine thiab hau nws mus rau lwm system Cheebtsam. Ob hom kev configurations yuav tsum distinguished nyob rau qhov ntsiab lus teb - nrog rau kev qhib thiab kaw cov chaw.

Nyob rau hauv rooj plaub thawj cov kua tswj valve thaum lub sij hawm kev lag luam ntawm lub piston muab ib tug dual tso zis. Hais tias yog, tsis muaj siab hloov nyob rau hauv lub tam sim no txoj hauj lwm ntawm lub piston, thiab kua tej zaum yuav muab xa mus rau lub luag hauj lwm voj voog los yog rov qab mus rau hauv lub valve. Nws regulates lub zog ntawm lub nras ntawm lub piston thiab cov valve.

Yuav kom nkag siab txog cov hauv paus ntsiab lus ntawm cov lag luam ntawm lub kaw system nws yog tsim nyog rov qab mus rau lub ntsiab txhais ntawm yog dab tsi lub hydraulics, thiab yuav ua li cas nws ua num ua ke nrog lub powertrain. Txij li thaum hydraulics nws tsuas yog tus infrastructure, uas yog lub koom haum los ntawm tej qhov units pab cov kua, nws yog ib zajlus kom hais tias lub zog ntawm cov chaw ua haujlwm yuav ua tau kiag li nyob rau cov kev ntawm cov kev khoom. Nyob rau hauv cov ntaub ntawv no ua hauj lwm no ua hauj lwm cov twj thiab li qub, kiag li kaw Circuit Court.

Classification los ntawm hom ntawm tsav

Txawv system, yog muab los ntawm unregulated thiab tswj actuators. Model xam tau tias yog unregulated hydraulic tsav, nyob rau lub twj tso kua mis siab qhia yog yeej ib txwm teev qhov tseem ceeb hnov los. Kaw cov ntaub ntawv yuav tsum muaj ntau tshaj li rau lub chaw pib theem ntawm cov load siab. Ntawd ces yog tsim tau ib lub sawb index, uas yog sib npaug zos rau cov twj tso kua mis.

Qhov tsis zoo ntawm no mechanism xws li loj losses nyob rau hauv lub hwj chim, txij li thaum tswj ib tug tas mus li kub siab inefficiently thaum uas tsis muaj loads. Raws li qhov no tswvyim, piv txwv li, yog tej zaum ua hydraulic excavator, cov kev tswj kev pab txhawb nqa cov ntsiab. Vim qhov no muaj nuj nqi lus dag ntiag tug hauj lwm nyob rau hauv cov nqe lus ntawm kev ruaj ntseg, cov manufacturers pub surpluses cardinality tej yam. Txawm li cas los, nyob rau hauv tib excavator unregulated tsav txhawb yuav supplemented nrog ib tug adjustable system uas yog optimized rau teb rau lub chaw ua hauj lwm attachments. Qhov no hom ntawm twj tso kua mis muab ib tug hydraulic tsav thiab lub siab nco vim nws ntsuas li qub thiab compensator nrog ib tug directional nyhuv.

hydraulic accumulators

Mechanisms thov kua zog extraction thiab accumulating pab kiag li lawm. Tej systems yog hu ua gidroemkostnymi zog thiab cov dej, uas yog nyob rau hauv siab thaum lub sij hawm ntawm lub lag luam. Nyob rau hauv cov ntaub ntawv no, lub roj teeb nws tus kheej yog feem ntau ib tug ib feem ntawm tus neeg kho tshuab hydraulic tsav.

Muaj ntau hom kev pab kiag li lawm - nyob rau hauv particular, pneumatic thiab caij nplooj ntoos hlav. Nyob rau hauv kev lag luam nws yog siv thiab accumulating high-siab hydraulics, uas chaw no yog ua los yooj yim tab sis xav tau load tuav loads. Txawm li cas los ntawm lub hom accumulator yuav tsum muaj lub siab ntawm ib tug predetermined qib, nrog rau qhov no exception thiab smoothing lub to ntawm kev co vim lub damping nyhuv.

Machinery rau hydraulic tshuab

Cov feem ntau xws mechanisms nyob rau hauv cov cav tov nrog attachments - nyob rau hauv tib lub excavators, tsheb laij thiab Ntxawm tsheb. Lug siv hydraulics nyob rau hauv lawv cov qauv lub designers ntawm cov Minsk Tsheb Laij Teb tsob nroj (MTZ).

Standard, uas yog siv nyob rau hauv cov tsheb laij muaj xws li twj, valve, thiab piping thooj voos kheej kheej. Duty voj voog, uas muab overcurrent hydraulics, yuav muaj tuaj raws li nram no: kua nkag mus rau los ntawm lub tank mus rau lub twj tso kua mis, yog xa mus rau lub distributor, yog ib tug piston pab pawg neeg thiab xa rov qab mus rau lub tank. Txoj kev hloov ntawm li qub mus rau lub thooj voos kheej kheej rau tus txheej txheem ntawm kev cai ntawm kev cob cog rua cov khoom neeg teb xov tooj los ntawm txoj kev levers uas tswj cov ndlwg ntawm cov kua nyob rau hauv lub piston pab pawg neeg, nyob ntawm seb qhov tam sim no ua hauj lwm.

Service hydraulic mechanisms

Tiv Thaiv txij nkawm yog feem ntau yog tas rau cov lubrication khiav hauj lwm ntawm ib tug neeg qhov chaw thiab cheebtsam uas hydraulic system. Thaum lub sij hawm qhov kev xeem tus neeg nyob rau hauv them nyiaj kuj qhia tej yam tshwm sim ntawm coj, deformation thiab kev puas tsuaj. Raws li ib tug txoj cai, hydraulics kho yog txo mus rau kev hloov ntawm piston hnab twb qhib lawm, rods thiab kaus mom. Nyob rau hauv cov kev txiav txim ntawm tshiab consumables nyob rau hauv daim ntawv ntawm cov O-rings.

xaus

Hydraulics - qhov no yog ib tug ntawm cov nyuaj txoj kev kom tau ib tug kho tshuab quab yuam txhais tau tias muaj. Yuav kom to taub li cas cov hydraulics, thiab dab tsi pab nws coj mus rau qhov nruab nrab neeg siv, yuav raug nplua raws li ib qho piv txwv ntawm siv cov khoom. Garden dej siv noj hauj lwm rau lub hydraulic engineering hauv paus ntsiab lus, siv ib tug tsawg kawg nkaus ntawm lub zog. Thaum ib tug ntau dua theem rau zoo xws li cov schemes khiav lag luam compressors thiab pneumatic cov cuab yeej.
