I. Kev txiav txim siab tseem ceeb rau kev xaiv qhov sib npaug li qub
Cov li qub feem ntau sawv cev rau qhov kev xaiv zoo tshaj plaws thaum lub kaw lus hydraulic yuav tsum muaj kev tswj hwm kev ua haujlwm tas mus li - xws li kev tswj ceev ceev, hloov siab tswj, lossis hloov txoj hauj lwm maj mam hloov -tab sis tsis thov ultra- siab tswj precision. Lawv tau dav siv tau nrog ntau lub tshuab ua lag luam, suav nrog cov tshuab txhaj tshuaj molding, tuag-casting tshuab, hydraulic presses, siv tshuab, thiab ua tiav cov khoom siv metallurgical.
Cov kev xaiv tseem ceeb los ntsuas suav nrog: txoj hauv kev tswj hwm, ntws thiab ntsuas kev ntsuas siab, tswj cov kab hluav taws xob, cov yam ntxwv hysteresis, cov lus teb zaus, thiab hom kev ua haujlwm (qhib- voj lossis ib nrab- kaw- voj). Cov li qub feem ntau yog tus nqi qis, muaj kev sib kis tau zoo dua piv rau servo li qub, thiab tuaj yeem ua tiav cov kev tswj hwm ntawm feem ntau ntawm cov khoom lag luam. Kev lag luam- cov txheej txheem kev xaiv tus qauv yog raws li hauv qab no: rau cov ntawv thov uas xav tau kev tswj xyuas qhov tseeb ntawm 1% mus rau 3% thiab cov lus teb zaus tsis tshaj 50 Hz, qhov sib npaug li qub yuav tsum tau muab qhov tseem ceeb.
II. Kev txiav txim siab tseem ceeb rau xaiv Servo Valves
Servo li qub yog siab -kawg, precision Cheebtsam nyob rau hauv lub teb ntawm electro- hydraulic tswj. Lawv yog cov yam ntxwv los ntawm xoom sib tshooj, tsawg kawg ntawm qhov chaw tuag, siab teb ceev, thiab ultra- siab tswj precision. Lawv cov ntawv thov tseem ceeb suav nrog cov tshuab kuaj khoom, servo presses, precision radar taug qab tshuab, cov cuab yeej siv dav hlau, thiab siab - cov rooj zaum ntsuas qhov tseeb.
Raws li cov qauv kev lag luam hauv teb chaws thiab thoob ntiaj teb, servo li qub feem ntau muaj qhov chaw tuag tsawg dua 3% ntawm cov hlab ntsha tawg, cov lus teb zaus tshaj 100 Hz, thiab kev tswj qhov tseeb hauv 0.1%. Lawv qhov tsis zoo suav nrog qhov nyuaj, qhov tseeb- qauv engineering; nruj me ntsis txog kev huv huv ntawm cov kua; tus nqi yuav khoom siab; thiab cov teeb meem tseem ceeb cuam tshuam nrog kev saib xyuas tom qab. Txoj Cai Xaiv: Rau cov ntawv thov uas tsis xav tau siab - qhov raug kaw- voj tswj, zam qhov muag tsis pom kev xaiv servo li qub; ua li ntawd tiv thaiv kev tsis sib haum xeeb, ua haujlwm luv luv, thiab cov nqi tu ntau dhau.
Tsib -Txoj Kev Xaiv Kev Xaiv Ceev rau Kev Tsim Qauv Hydraulic
Hauv kev tsim qauv engineering, ib qho yooj yim tsib- cov txheej txheem tso cai rau koj kom sai sai txheeb xyuas qhov tsim nyog ntawm kev taw qhia valve, proportional valve, lossis servo valve, yog li ua tau zoo kom tsis txhob xaiv qhov yuam kev:
1. Ua ntej, txiav txim siab seb lub kaw lus puas xav tau kev hloov kho tas li; Yog tias tsis tas yuav hloov kho tas li, ncaj qha xaiv lub valve directional.
2. Txiav txim siab seb lub kaw lus puas yog qhov siab -precision, siab -dynamic kaw- voj tswj qhov system; yog tias nws tsis ua tau raws li cov txheej txheem no, mus rau qhov proportional valve xaiv qeb.
3. Qhia meej meej cov cuab yeej tswj xyuas qhov tseeb, cov lus teb ceev, thiab cov lus teb zaus; rau cov ntawv thov uas xav tau kev ua haujlwm nruab nrab, ncaj qha xaiv lub valve proportional.
4. Ntsuam xyuas ntawm - qhov chaw ua haujlwm ib puag ncig, cov kev xav tau ntawm kev lim dej, thiab kev saib xyuas yav tom ntej; Yog tias cov xwm txheej no raug txwv, xaiv lub servo valve tsis pom zoo.
5. Muab hais tias tag nrho cov khoom yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua, ua qhov tseem ceeb ntawm cov kev daws teeb meem valve uas muab cov nqi qis dua, cov qauv yooj yim dua, thiab kev saib xyuas yooj yim dua.
Tsis muaj ib qho "zoo tshaj" hydraulic valve-tsuas yog lub valve uas zoo tshaj plaws rau cov kev ua haujlwm tshwj xeeb. Directional li qub ua tau zoo ntawm kev ua cov txheej txheem yooj yim, muab tus nqi siab - ua haujlwm tau zoo thiab txhim khu kev qha; proportional li qub tawm tsam qhov sib npaug ntawm kev tswj tsis tu ncua thiab kev ua haujlwm ntawm kev lag luam, ua rau lawv haum rau feem ntau ntawm cov ntawv thov kev lag luam; servo li qub tshwj xeeb hauv siab -kawg, precision kaw- voj tswj, xa sab saum toj -tier dynamic kev ua tau zoo.
Lub hauv paus ntawm hydraulic system tsim nyob rau hauv kom nkag siab txog kev ua tau zoo ciam teb, tswj logic, thiab kev ua haujlwm ntawm peb hom valve. Los ntawm kev sib piv ntawm lub valve rau cov txheej txheem tshwj xeeb, tag nrho cov hydraulic system tuaj yeem ua haujlwm tau zoo dua, txuag lub zog, tswj kev ruaj ntseg, thiab ua tiav lub neej ua haujlwm ntev.
