Servo Valve SM4-20 (15) 57-80 / 40-10-H607hyog cov tseem ceeb tswj lub ntsiab ntawm lub ncu turbine digital elemress Electro-hydraulic tswj system (DEH). Nws cov xeeb ntxwv Valve-Valve Tes Tsho txuam kev tshem tawm feem ntau tsuas yog micrometer (txog 3-5μm). Raws li kev ua haujlwm nruab nrab, kev huv huv ntawm hluav taws-resistant roj ncaj qha cuam tshuam cov lus teb zoo thiab lub neej ntawm servo valve. Yog tias muaj cov paug tsis sib xws (xws li hlau chips, oxides, thiab lwm yam) hauv cov roj, nws yuav ua rau muaj cov teeb meem hauv qab no:

1. 1. Valve core yaig thiab hnav: cov tawv tawv cuam tshuam rau lub valve cov roj ntws, ua rau cov roj ntsha
2. 2. Dynamic teb tsis tiav: me me block thaiv lub nozzle bazzle bazle bazzle bazzle bazle bazzle bazle bazle bazle bazzle core zog clearance, ua rau jamming, lag los yog txawm ua tiav jamming.
3. 3. Electrochemical corrosion: Yog tias cov roj tiv taus (xws li cov roj av tsis yeem (cov roj av tsis zoo li)

I. Kev Tshawb Xyuas Kev Ntsuam Xyuas: Kev tsom xam ntawm qhov ua rau ntawm lub sijhawm luv luv tsis ua haujlwm ntawm lub zog servo valve nyob rau hauv lub zog fais fab

Ua tsis tiav Prenomenon: Ib qho tshiab yuav SM4-20 (15) 57-80 / 40-10-H607hSERVO VALVENyob rau hauv lub zog nroj tsuag ua tsis tiav tom qab tsuas yog ob hnub ntawm kev ua haujlwm tom qab kev teeb tsa. Disassembly qhia cov kev khawb thiab hnav cov cim ntawm lub valve core nto.

Hauv paus ua rau tsom xam:

1. Cov roj ntxiv tsis raug tshuaj tsis raug kho

Cov roj hluav taws kub hluav taws xob muaj peev xwm nqa NAS7-8 qib tsis huv thaum tawm hauv lub Hoobkas, thaum lub sij hawm cov roj huv si kom ncav cuag NAS5 qib lossis hauv qab. Lub zog cog cog lus tsis ua 24-72 teev kev khiav tawm ntawm cov roj tshiab raws li cov khoom siv roj lim (xws li cov hlau loj-ua rau cov hlau oxides ncaj qha nkag mus rau lub servo valve.

2. Realidual ViFeed los ntawm kev teeb tsa lub cev

Lub vuam slag sab laug sab laug los ntawm pipeline vuam thiab cov hlau khib nyiab sib xyaw hauv lub sijhawm cov txheej txheem teeb tsa tsis raug tshem tawm kiag li. Cov kuab paug no tau ua "micro-txiav" nyhuv rau kev siv roj siab siab (feem ntau 14-21mpa), hnav tam sim ntawd tawm ntawm lub valve core tseem ceeb.

3. Lub cev tsis ua haujlwm tsis ua haujlwm

Lub ntsiab lus lim lim yuav tsis hloov nyob rau hauv lub sijhawm ntawm lub taub (xws li ua tsis pom kev yooj yim kom nqus tau lub suab nrov sib txawv, ua rau nkag mus rau hauv qhov chaw thov nkag mus rau hauv servo valve.

Ii. Cov Lus Taw Qhia

Rau SM4-20 (15) 57-80 / 40-10-h607-h607-h607-h607-h60 cov kev ntsuas yuav tsum tau ua kom ntseeg tau roj huv:

1. Cov roj roj txuas ntxiv rau cov roj

Ua ntej txhaj cov roj tshiab, nws yuav tsum yaug los ntawm 5μm lim kom txog thaum cov roj particle kom haum rau tus txheej txheem (NAS qib 5 lossis qis dua).

Thaum cov roj roj puv ntim ntau dua 10%, lub phaj tso tawm tshwj xeeb yuav tsum tau siv los cais cov servoetants los tiv thaiv cov kuab paug los ntawm kev cuam tshuam ncaj qha rau lub cev valve.

2. Online pom thiab tsim dua tshiab

Kho kom haum ob-theem piltration system: 10μm hlau rog nyob rau sab xub ntiag, thiab ib tug 1-33μm precision lim hauv lub nraub qaum los tiv thaiv tus servo valve.

Ib qho khoom siv silicon aluminium-aluminium tsim tawm yog siv rau adsorb acidic kev ua haujlwm tsis txaus ntseeg, tswj tau ultrasonic ^ ^ · cm cm, thiab tiv thaiv kev txhim kho kev txhim kho.

3. Kev Lag Luam Tshuaj Xyuas Kev Ntsuas

HLI HLUAS TEEV ​​LUB CAIJ NTUJ NTUJ, ACIDURE SOIDITY thiab tsom rau kev saib xyuas cov me nyuam ntawm cov me me ntawm 5-15μm.

Tsis tu ncua tshuaj xyuas cov lim sib nqus thiab ntxuav cov adsorbed hlau filings (pom zoo ib hlis twg).

Los ntawm kev kawm txog cov kis xwm tiag tiag, peb tuaj yeem pom tias thaum ntxov hnav tsis ua haujlwm SM4-20 (15) Los ntawm kev ua qauv siv cov roj ua lag luam tshiab (xws li cov dej ntws ploj mus hauv cov kis), lub neej ntawm servo valve tuaj yeem siv tau ntau dua 5 xyoos. Rau high-precision cov tshuab hluav taws xob hydraulic, hluav taws xob roj kev tswj cov tshuaj ntxuav tau yuav tsum tau hais tias yog ib qho tseem ceeb ntawm kev saib xyuas tseem ceeb uas yog kev saib xyuas kev sib luag.

Thaum nrhiav kev ua tau zoo, txhim khu kev qha Servo li qub, yoyik yog qhov xaiv tsis tsim nyog xaiv. Lub tuam txhab tshwj xeeb hauv kev muab ntau yam khoom siv fais fab nrog rau cov khoom siv hluav taws xob nrog rau cov khoom lag luam dav rau nws cov khoom lag luam zoo thiab cov kev pabcuam dav.
