XKAL00050 Excavator R160W9A R170W7 Solenoid Valve Coil

Valavu ya solenoid ili ndi magawo awiri: koyilo yamagetsi ndi maginito pachimake, ndi thupi la valavu lomwe lili ndi mabowo amodzi kapena angapo.Pamene koyilo mu valavu solenoid ndi mphamvu kapena de-energized, ntchito maginito pachimake kumapangitsa madzi kudutsa valavu thupi kapena kulekanitsa, kusintha njira madzi.Pamene magetsi akudutsa pa koyilo, valavu ya solenoid ikhoza kuyaka.Inde, chifukwa choyaka chingakhale chosiyana.Tiyeni tiwone chifukwa chomwe valavu ya solenoid imawotchedwa.

Zifukwa zakunja:

Kuchita bwino kwa valve ya solenoid kumagwirizana kwambiri ndi ukhondo wa sing'anga yamadzimadzi.Makanema ambiri adzakhala ndi tinthu tating'onoting'ono kapena kuwerengetsa media.Tinthu ting'onoting'ono timeneti timalumikizana pang'onopang'ono ndi mtima wa valve ndikuwumitsa pang'onopang'ono.Anthu ambiri adapeza kuti ikugwirabe ntchito usiku watha, ndipo valavu ya solenoid sinatsekulidwe m'mawa wotsatira.Pamene anachotsedwa, panali wandiweyani wosanjikiza wa madipoziti calcified mu valavu.Mkhalidwe woterewu ndi wamba, ndipo ndicho chinthu chachikulu chomwe chimayambitsa kuwotcha kwa valve solenoid, chifukwa pamene mtima wa valve watsekedwa, FS = 0, ndiyeno I = 6i, panopa idzawonjezeka kasanu ndi kamodzi, ndipo koyilo wamba idzawotchedwa mosavuta.

Zifukwa zamkati:

Chilolezo choyenera pakati pa manja a spool a valve solenoid ndi valavu ndi yaying'ono kwambiri (yosakwana 0) 008mm), yomwe nthawi zambiri imayikidwa mu chidutswa chimodzi.Zonyansa zamakina zikalowa kapena mafuta opaka ndi ochepa kwambiri, ndizosavuta kukakamira.Njira yochizira ikhoza kukhala kuboola waya wachitsulo kuchokera pabowo laling'ono m'mutu kuti ibwererenso.Njira yothetsera vutoli ndikuchotsa valavu ya solenoid, kuchotsa valavu ya valve ndi manja apakati, ndikugwiritsa ntchito CCI4.Kuyeretsa kulimbikitsa kusinthasintha kwapakati pa valve mu manja a valve.Pamene disassembling, kulabadira unsembe zinayendera ndi kunja mawaya malo a mbali iliyonse, kusonkhanitsanso ndi waya molondola, ndi kuwona ngati bowo jekeseni mafuta watsekedwa ndipo ngati mafuta opaka ndi okwanira.Ngati valavu ya solenoid yatenthedwa, waya wa solenoid valve akhoza kuchotsedwa ndikuyesedwa ndi multimeter.Ngati ndi lotseguka, valavu ya solenoid imawotchedwa.Chifukwa chake ndi chakuti koyiloyo imakhala yonyowa, yomwe imayambitsa kutsekemera kosauka komanso kutuluka kwa maginito, komwe kumabweretsa kuwonjezereka kwamakono ndi kuyaka kwa koyilo, kotero kuti mvula imalepheretsa kulowa mu valve solenoid.Kuonjezera apo, kasupe ndi wokhazikika, mphamvu yowonongeka ndi yaikulu kwambiri, chiwerengero cha kutembenuka kwa koyilo ndi kochepa kwambiri, ndipo mphamvu yoyamwa sikwanira, yomwe ingathenso kulimbikitsa kuyaka kwa koyilo.Pakachitika ngozi, batani lamanja pa koyilo limatha kugwira ntchito moyenera kuti amalize "0" ndikugunda "1", zomwe zimapangitsa kuti valavu itseguke.
