Thaum siv, solenoid directional valve yuav hnav thiab thaum qib ntawm hnav mus txog rau qee yam, solenoid directional valve yuav tawg ces tsis ua haujlwm. Qhov yooj yim qhov chaw ntawm solenoid directional valve yog raws li nram no:
1. thawb pas nrig ntawm Electromagnetic raj yog luv vim hnav
Push pas nrig ntawm Electromagnetic raj laub valve caij txav thaum armature txav. Push pas nrig tsis sib xyaw nrog lub valve yog li yuav tsum muaj hnav hauv kev thawb mus tas li.
Nyob rau hauv lub sij hawm ntev ntawm lub siab zaus ntawm kev thim rov qab, thawb pas nrig yuav luv dua vim hnav ua rau lub valve tsis thim rov qab mus rau qhov chaw zoo ces cuam tshuam rau kev ua haujlwm ntawm solenoid directional valve.
Nyob rau hauv cov xwm txheej saum toj no, thov hloov lub laub tshiab thiab cov qauv ntawm lub laub pas nrig yuav tsum zoo ib yam li qhov qub.
2. electromagnet tawg
Electromagnet puas yog ib qho txhaum ntawm solenoid directional valve.
Qhov laj thawj tseem ceeb ntawm qhov tshwm sim no yog vim muaj teeb meem zoo xws li cov txheej txheem tsis zoo ntawm cov hlau hlau los yog txoj kab uas hla ntawm cov khoom siv hlau tsis tshua muaj ua rau cov hlau tsis yooj yim rau overheat.
Yog tias qhov txhaum tshwm sim los ntawm cov khoom zoo, cov neeg siv tuaj yeem pom pom tseeb tom qab solenoid directional valve tau ua haujlwm rau ob peb teev.
Yog tias coil puas lawm tom qab ua haujlwm rau ob peb hnub, qhov laj thawj yuav yog qhov siv ib puag ncig hauv feem ntau qhov xwm txheej.
3. Sab nraud txoj kab uas hla ntawm lub valve yog hnav
Yog vim li cas ntawm kev hnav ntawm sab nraud txoj kab uas hla ntawm lub valve yog tib yam li sab hauv txoj kab uas hla ntawm lub valve tshwj xeeb tshaj yog thaum muaj ntau dhau thiab loj impurities nyob rau hauv cov roj, uas yuav ua rau hnyav hnav ntawm solenoid directional valve.
Hom kev hnav no tsis tuaj yeem zam tau tab sis txuas ntxiv lub neej ntawm solenoid directional valve thiab ua haujlwm ntawm qhov xwm txheej zoo yog ua tau. Yog li thov xyuas thiab ntxuav cov roj hydraulic tsis tu ncua.
Rau cov khoom tshwj xeeb ntawm peb-tis solenoid directional valve, nws hardness ncav cuag ntau tshaj HRC60 yog li nws yog hnav tsis kam ntau dua li ib txwm.
4. pib dua caij nplooj ntoos hlav qaug zog los yog puas
Qhov kev ua txhaum no muaj feem xyuam rau cov khoom ntawm lub caij nplooj ntoos hlav. solenoid directional valve txais txoj hlua caij nplooj ntoos hlav dua li tuaj ntawm lwm lub teb chaws nrog Nto dyed dub, zoo Elastic kev ua tau zoo thiab qaug zog ua haujlwm.
Cov txheej txheem ntawm tus kov tuaj yeem txhim kho corrosion ntawm lub caij nplooj ntoos hlav kom lub caij nplooj ntoos hlav zoo li no nrog lub neej ntev. thaum rov pib caij nplooj ntoos hlav yog qaug zog lossis puas, thov hloov ob sab ntawm lub caij nplooj ntoos hlav. Los ntawm txoj kev, qhov ntev ntawm lub caij nplooj ntoos hlav yuav tsum tau ntsib nrog tus nqi tsim ntawm solenoid directional valve.
5. Internal txoj kab uas hla ntawm valve ntsiab yog hnav
Lub ntsiab valve ua kom nquag mus-thiab-fro txav hauv lub bore ntawm lub cev valve. Txawm hais tias muaj cov roj dab dej hauv lub valve ntawm solenoid directional valve, uas tuaj yeem ua rau tag nrho cov roj ntawm qhov chaw sib cuag kom txo qis, qhov hnav ntawm sab hauv txoj kab uas hla ntawm lub valve tsis tuaj yeem zam tau vim kev ua haujlwm ntawm solenoid directional valve.
Lub cev ntawm solenoid directional valve txais nodular cam khwb cia hlau raws li cov khoom thiab peb-tis solenoid directional valve yog nrog tshwj xeeb raw khoom piv los txhim kho hardness ntawm valve lub cev nyob rau hauv tej yam degree kom tsis txhob puab bore hnav, uas yog txawv los ntawm ib txwm solenoid directional valve.
Raws li kev hnav khaub ncaws sab hauv, cov neeg siv tuaj yeem kho lossis hloov ua haujlwm. Thaum cov neeg siv txiav txim siab hloov qhov chaw, thov saib xyuas seb lub cev lub cev tshiab puas phim cov khoom muaj feem cuam tshuam los ntawm cov laus xws li Electromagnetic raj, foob nplhaib thiab lwm yam.
6. tsis tshua muaj teeb meem tshwm sim
Cov lus nug saum toj no feem ntau tshwm sim rau solenoid directional valve tab sis kuj tseem muaj qee cov lus nug tsis tshua muaj xws li tsis ruaj tsis khov, hluav taws xob tsis ruaj khov, ua rau muaj kev kub ntxhov los ntawm kev cuam tshuam loj.
Raws li kev tshawb xav ua haujlwm ntawm electromagnet, thaum lub caij valve ntawm solenoid directional valve tau daig ua rau lub tshuab hluav taws xob ua haujlwm tab sis armature tsis tuaj yeem txav mus rau qhov chaw. Raws li qhov tshwm sim, qhov kub ntawm lub kauj yuav nce siab heev thiab hlawv hauv lub sijhawm luv luv.
Yog li thaum coil hlawv hauv kev siv, thov xyuas seb electromagnet puas ua haujlwm zoo thaum xub thawj. Tom qab tshem tawm qhov yuam kev ntawm lub valve daig, thov hloov cov kauj tshiab. Yog tias tsis ua li ntawd, lub kauj yuav hlawv rau lwm zaus.
Sab hauv txoj kab uas hla ntawm kauj ntawm solenoid directional valve yog 20mm tab sis cov chaw tsim khoom sib txawv muaj qhov sib txawv. Yog li thaum serviceman hloov tshiab coil, puab txoj kab uas hla thiab qhov ntev ntawm lub kauj yuav tsum zoo ib yam li tus thawj yog tias tsis yog, lub kauj yuav siv tsis tau.
