XKAL00050 Excavator R160W9A R170W7 Solenoid Valve Chev

Lub solenoid valve muaj ob ntu: lub tshuab hluav taws xob electromagnetic thiab cov tub ntxhais sib nqus, thiab lub cev valve nrog ib lossis ntau qhov. Thaum lub coil nyob rau hauv lub solenoid valve yog energized los yog de-energized, kev khiav hauj lwm ntawm lub magnetic core yuav ua rau cov kua dhau los ntawm lub valve lub cev los yog disconnect, hloov cov kev taw qhia ntawm cov kua. Raws li tam sim no dhau los ntawm lub kauj, lub solenoid valve coil yuav hlawv tawm. Tau kawg, qhov ua rau hlawv yuav txawv. Cia peb saib yog vim li cas vim li cas lub solenoid valve coil raug hlawv.

Cov laj thawj sab nraud:

Kev ua haujlwm du ntawm solenoid valve yog ze ze rau kev huv ntawm cov kua nruab nrab. Ntau cov xov xwm yuav muaj qee qhov me me los yog xov xwm calcification. Cov khoom me me no yuav maj mam txuas mus rau lub plawv ntawm lub valve thiab maj mam harden. Ntau tus neeg pom tias nws tseem ua haujlwm ib txwm hmo ua ntej, thiab solenoid valve tsis tuaj yeem qhib rau tag kis. Thaum nws raug tshem tawm, muaj txheej tuab ntawm calcified deposits nyob rau hauv lub valve. Cov xwm txheej zoo li no tshwm sim, thiab nws tseem yog qhov tseem ceeb uas ua rau kub hnyiab ntawm solenoid valve, vim tias thaum lub plawv ntawm lub valve yog daig, FS = 0, thiab tom qab ntawd I = 6i, tam sim no yuav nce rau 6 npaug, thiab cov coil zoo tib yam yuav raug hlawv yooj yim.

Cov laj thawj sab hauv:

Qhov haum clearance ntawm lub tes tsho spool ntawm solenoid valve thiab lub valve yog me me (tsawg dua 0.008mm), uas yog feem ntau ntsia rau hauv ib thooj. Thaum cov neeg kho tshuab impurities nkag los yog lubricating roj tsawg dhau, nws yooj yim rau daig. Txoj kev kho mob tuaj yeem tho cov hlau hlau los ntawm lub qhov me me hauv lub taub hau kom nws rov qab. Cov kev daws teeb meem tseem ceeb yog tshem tawm lub solenoid valve, tshem tawm lub valve tub ntxhais thiab lub tes tsho valve, thiab siv CCI4. Kev tu kom txhawb qhov yooj ntawm lub valve tseem ceeb hauv lub tes tsho valve. Thaum disassembling, xyuam xim rau lub installation ib ntus thiab sab nraud thaiv txoj hauj lwm ntawm txhua qhov chaw, reassemble thiab xaim kom raug, thiab xyuas seb cov roj txhaj qhov yog thaiv thiab seb cov roj lubricating puas txaus. Yog hais tias lub solenoid valve coil yog hlawv, lub solenoid valve thaiv yuav raug tshem tawm thiab ntsuas nrog ib tug multimeter. Yog tias nws qhib, lub solenoid valve coil yog hlawv. Yog vim li cas yog vim li cas cov kauj yog ntub dej, uas ua rau cov rwb thaiv tsev tsis zoo thiab cov hlau nplaum sib nqus, uas ua rau cov hluav taws xob ntau dhau thiab kub hnyiab ntawm cov kauj, yog li nag los tiv thaiv kev nkag mus rau hauv solenoid valve. Tsis tas li ntawd, lub caij nplooj ntoos hlav yog ruaj khov, lub zog recoil loj dhau lawm, tus naj npawb ntawm cov lem ntawm lub kauj yog me dhau, thiab lub zog nqus dej tsis txaus, uas tuaj yeem txhawb nqa lub coil hlawv. Thaum muaj xwm txheej ceev, phau ntawv khawm ntawm lub kauj tuaj yeem ua haujlwm ib txwm ua kom tiav "0" txoj haujlwm thiab ntaus "1" txoj haujlwm, yog li ua kom lub valve qhib.
