Hydraulic valve kho yog ib txoj haujlwm zoo heev uas yuav tsum muaj kev nkag siab tob txog cov qauv, qauv thiab kev ua haujlwm ntawm hydraulic system.Kab lus no yuav qhia txog kev nthuav dav, kev tshuaj xyuas thiab kev sib dhos ntawm hydraulic li qub.
1. Disassembly ntawm hydraulic valve
Kev npaj ua haujlwm: Ua ntej disassembling lub hydraulic valve, koj yuav tsum xub nkag siab txog txoj cai ua haujlwm ntawm hydraulic system, hom thiab cov yam ntxwv ntawm hydraulic valve, thiaj li xaiv cov cuab yeej disassembly tsim nyog.Nyob rau tib lub sijhawm, xyuas kom meej tias lub tshuab hydraulic tau nres ua haujlwm thiab txiav tawm lub zog hluav taws xob los tiv thaiv kev sib tsoo.
Disassembly sequence: Lub disassembly sequence ntawm hydraulic valve yuav tsum ua raws li lub hauv paus ntsiab lus ntawm sab nraud mus rau sab hauv thiab los ntawm sab saum toj mus rau hauv qab.Disassemble cov khoom txuas sab nraud ua ntej, thiab tom qab ntawd disassemble cov khoom sab hauv.Qhov no tiv thaiv kev puas tsuaj lossis xau ntawm qhov chaw los ntawm kev txiav txim tsis raug cai.
Txoj kev disassembly: Lub ntsiab disassembly txoj kev ntawm hydraulic valve yog raws li nram no:
(1) Threaded kev twb kev txuas: Rau hydraulic li qub nrog threaded kev twb kev txuas, ib tug ciaj ntswj los yog socket ciaj ntswj yuav siv tau los disassemble lawv.Thaum disassembling, xyuam xim rau siv txawm tias quab yuam kom tsis txhob nruj dhau los yog xoob dhau.
(2) Flange kev twb kev txuas: Rau flange-connected hydraulic li qub, ib tug ciaj ntswj los yog ntsia liaj qhov rooj tensioner yuav siv tau los disassemble nws.Thaum disassembling, xyuam xim rau zawm lub bolts diagonally kom tsis txhob to.
(3) Vuam kev sib txuas: Rau hydraulic li qub nrog kev sib txuas vuam, vuam cov cuab yeej yuav tsum tau siv rau disassembly.Thaum disassembling, ua tib zoo saib xyuas kom tsis txhob muaj qhov sib tsoo los ntawm kev tawg thiab ua rau kom tawg.
Lus Cim: Thaum disassembled lub hydraulic valve, xyuam xim rau cov ntsiab lus hauv qab no:
(1) Ua kom huv si: Khaws qhov chaw ua haujlwm thiab qhov chaw huv si thaum lub sij hawm disassembly txheej txheem kom tsis txhob impurities nkag mus rau hauv hydraulic system.
(2) Tiv thaiv kev puas tsuaj: Tsis txhob siv cov cuab yeej thiab cov txheej txheem tsis tsim nyog thaum lub sij hawm disassembly los tiv thaiv kev puas tsuaj rau cov khoom.
(3) Cov ntaub ntawv sau tseg: Thaum lub sij hawm disassembly txheej txheem, hom, qauv, installation qhov chaw thiab lwm yam ntaub ntawv ntawm hydraulic valve yuav tsum tau sau tseg rau tom ntej kev soj ntsuam thiab sib dhos.
2. Kev tshuaj xyuas ntawm hydraulic li qub
Kev tshuaj xyuas qhov tshwm sim: Tshawb xyuas cov tsos ntawm hydraulic valve rau kev puas tsuaj, deformation, xeb, thiab lwm yam. Yog tias muaj kev puas tsuaj, hloov nws raws sijhawm.
Kev kuaj xyuas lub foob: xyuas seb cov ntsaws ruaj ruaj ntawm hydraulic valve puas hnav, hnub nyoog, puas, thiab lwm yam. Yog tias puas lawm, lawv yuav tsum tau hloov raws sijhawm.
Kev tshuaj xyuas lub caij nplooj ntoos hlav: xyuas seb lub caij nplooj ntoos hlav ntawm hydraulic valve yog deformed, tawg, elastically tsis ua hauj lwm, thiab lwm yam. Yog tias nws puas lawm, nws yuav tsum tau hloov raws sij hawm.
Piston tshuaj xyuas: Tshawb xyuas lub piston ntawm hydraulic valve rau hnav, khawb, deformation, thiab lwm yam. Yog tias nws puas lawm, hloov nws raws sijhawm.
Kev tshuaj xyuas lub hauv paus ntawm lub valve: xyuas cov tub ntxhais valve ntawm hydraulic valve rau hnav, khawb, deformation, thiab lwm yam. Yog tias nws puas lawm, hloov nws raws sijhawm.
Flow check: Los ntawm kev ntsuas qhov ntws ntawm hydraulic valve, txiav txim siab seb nws qhov kev ua haujlwm zoo li cas.Yog tias tus nqi ntws tsis zoo, qhov chaw sab hauv ntawm lub hydraulic valve yuav puas los yog thaiv, thiab yuav tsum tau kuaj xyuas thiab kho ntxiv.
Kev ntsuas siab: Los ntawm kev ntsuas lub siab ntawm hydraulic valve, txiav txim siab seb nws cov kev ua haujlwm zoo li cas.Yog tias lub siab tsis zoo, qhov chaw sab hauv ntawm lub hydraulic valve yuav puas los yog thaiv, thiab yuav tsum tau soj ntsuam thiab kho ntxiv.
Kev tshuaj xyuas tsis zoo: Los ntawm kev soj ntsuam cov dej ntws ntawm hydraulic valve, txiav txim siab seb nws qhov kev sib khi zoo li cas.Yog tias qhov xau loj heev, lub foob yuav raug puas los yog tsis raug, yuav tsum tau tshuaj xyuas thiab kho ntxiv.
3. Kev sib dhos ntawm hydraulic valve
Ntxuav qhov chaw: Ntxuav lub disassembled hydraulic valve qhov chaw kom tshem tawm impurities thiab roj stains kom huv si ntawm qhov chaw.
Hloov cov khoom puas ntsoog: Raws li kev tshuaj ntsuam xyuas, hloov qhov puas hydraulic valve qhov chaw kom ntseeg tau tias qhov kev ua tau zoo thiab qhov loj ntawm cov khoom tshiab zoo ib yam nrog cov khoom qub.
Kev sib dhos ua ntu zus: Kev sib dhos ua ntu zus ntawm hydraulic valve yuav tsum ua raws li lub hauv paus ntsiab lus ntawm sab hauv mus rau sab nraud thiab hauv qab mus rau sab saum toj.Sib sau cov khoom sab hauv ua ntej, thiab tom qab ntawd sib sau cov khoom txuas sab nraud.Qhov no tiv thaiv kev puas tsuaj lossis xau ntawm qhov chaw los ntawm kev sib dhos tsis raug.
Kev sib dhos txoj kev: Lub ntsiab sib dhos txoj kev ntawm hydraulic li qub yog raws li nram no:
(1) Threaded kev twb kev txuas: Rau hydraulic li qub nrog threaded kev twb kev txuas, ib tug ciaj ntswj los yog socket ciaj ntswj yuav siv tau los ua ke.Thaum sib sau ua ke, xyuam xim rau kev siv txawm tias quab yuam kom tsis txhob nruj dhau los yog xoob dhau.
(2) Flange kev twb kev txuas: Rau flange-connected hydraulic li qub, ib tug ciaj ntswj los yog ntsia liaj qhov rooj tensioner yuav siv tau los ua ke.Thaum sib sau ua ke, xyuam xim rau zawm lub bolts diagonally kom tiv thaiv kom tsis txhob tawg.
(3) Vuam txuas: Rau hydraulic li qub nrog kev sib txuas vuam, cov cuab yeej vuam yuav tsum tau siv los ua ke.Thaum sib sau ua ke, xyuam xim tiv thaiv cov welds los ntawm kev tawg thiab ua rau to.
Lus Cim: Thaum lub sij hawm sib dhos txheej txheem ntawm hydraulic li qub, xyuam xim rau cov ntsiab lus hauv qab no:
(1) Ua kom huv: Khaws qhov chaw ua haujlwm thiab qhov chaw huv si thaum lub sijhawm sib dhos kom tsis txhob muaj impurities nkag mus rau hauv hydraulic system.
(2) Tiv thaiv kev puas tsuaj: Tsis txhob siv cov cuab yeej thiab cov txheej txheem tsis tsim nyog thaum sib dhos los tiv thaiv kev puas tsuaj rau cov khoom.
(3) Tshawb xyuas lub foob: Tom qab sib dhos, xyuas qhov kev sib khi ntawm lub hydraulic valve kom paub tseeb tias tsis muaj qhov xau.
Hydraulic valvekho yog ib txoj hauj lwm zoo heev uas yuav tsum muaj kev nkag siab tob txog cov qauv, qauv thiab kev ua haujlwm ntawm hydraulic system.Los ntawm kev paub txog kev tshem tawm, kev tshuaj xyuas thiab kev sib dhos ntawm hydraulic li qub, kev saib xyuas kev ua haujlwm thiab kev ua haujlwm zoo tuaj yeem txhim kho tau zoo thiab kev ua haujlwm ntawm hydraulic system tuaj yeem ua kom ntseeg tau.
