Vavu Yabwino Yabwino ya Solenoid 121-1491 Control Valve VE Zigawo za Pampu za Caterpillar Excavator CAT320B 320C

Mavavu a Solenoid mu gawo lakutali, koyiloyo sikhala ndi mphamvu, sipadzakhala kugwiritsa ntchito mphamvu, kotero koyiloyo sidzawotcha. Ndipo ndi sing'anga kuthamanga ndi kasupe mphamvu ndi zinthu zina, kapena chifukwa cha pachimake kuyamwa mphamvu sikokwanira chifukwa zazikulu ndi malo amodzi chitsulo pachimake kuyamwa, mu koyilo akupereka amphamvu boma, koyilo adzatulutsa kuchuluka kwa kuyamwa, ndipo pachimake chachitsulo chokhazikika chidzalandira kuyamwa kwa ma elekitiroma ndi mphamvu ya maginito yokhazikika yamphamvu yakugonjetsa mphamvu ya masika ndi kuthamanga kwapakati komanso kuyamwa kwachitsulo chokhazikika, zomwe zingapangitse kutsegulidwa kwa valavu, ndi valavu thupi valavu doko. Tsegulani pakamwa pa valavu ya valavu, pansi podula mphamvu ya koyilo, valavu ya solenoid, chitsulo chosasunthika chosonyeza dziko loyamwa, ndi valavu ya solenoid kuti mukhale ndi valavu yotseguka. Mu valavu ya solenoid kuti itseke, koyiloyo imatulutsa reverse-current, maginito opangidwa ndi maginito opangidwa ndi chitsulo chosuntha mbali ina, mothandizidwa ndi kukana amuna kapena akazi okhaokha kufooketsa chitsulo chosuntha pachitsulo chokhazikika. pachimake cha kukopa, chifukwa mu kulekana kwa kusuntha ndi malo amodzi chitsulo mitima, kuti valavu adzakhala chatsekedwa valavu thupi valavu pakamwa.

Pofuna kuteteza ntchito khola valavu solenoid, kuti bwino kupewa zikamera wa Kutentha koyilo ndi mavuto ena, mu ntchito ya valavu solenoid ayenera kulabadira yokonza kasamalidwe, mchitidwe, kuchita mfundo zotsatirazi:

Choyamba, kwa valavu ya solenoid yoyendetsa ndege, malingana ndi zofunikira zowunikira kuti muwone kusiyana kwapaipi, ngati kuthamanga kwapadera kuli kochepa kwambiri kumapangitsa kuti valavu ya solenoid isagwire ntchito bwino. Ngati kupanikizika kosiyana kuli kochepa kwambiri, tiyenera kusankha ma valve a solenoid molunjika. Ngati kupanikizika kosiyana kuli kwakukulu kwambiri, kudzatsogolera kupamwamba kuposa mtengo wamtengo wapatali wa valavu ya solenoid, sikungathe kutsimikizira ntchito yake yachibadwa, panthawiyi kugwiritsa ntchito valavu yapamwamba ya solenoid.

Kachiwiri, zinthu zambiri zomwe zili pansi pa valavu ya solenoid zimayikidwa mozungulira, ngati mbali ya kuyikapo idzachititsa kuti valavu itseke mwamphamvu ndikuyambitsa kutuluka kwamkati ndi mavuto ena. Pachifukwa ichi, pewani kukwera m'mbali momwe mungathere.

Chachitatu, ngati valavu solenoid kwa nthawi yaitali, adzatsogolera pisitoni ndi mpando valavu pakati kusindikiza sikokwanira, mu mkhalidwe wotero ayenera kachiwiri akupera pisitoni kusindikiza pamwamba, ndiyeno valavu mpando akupera.

Chachinayi, mu ntchito ya polojekitiyi, kuyang'ana valavu isanayambe komanso itatha kuyeza kuthamanga, kuonetsetsa kuti kupanikizika kwa ntchito sikuli kwakukulu kuposa mtengo wamtengo wapatali, kusiyana kosiyana kogwira ntchito kuyenera kuwongoleredwa mumtundu womveka wosiyana. , mu ntchito ya kupanikizika ndipamwamba kuposa kupanikizika kosasunthika kapena kupitirira kuposa kuthamanga kwapadera, tiyenera kusiya kugwiritsa ntchito ma valve a solenoid, ndipo m'kupita kwa nthawi, mavavu asanayambe komanso atatha, kuti tipewe valavu ya solenoid. kuphulika ndi kutayikira ndi zina.

Chachisanu, pambuyo unsembe wa mavavu solenoid, kuchita zoyeserera TV kangapo, pambuyo kudziwa zake zachibadwa asanaikidwe ntchito.

Chachisanu ndi chimodzi, kukhala otsika angstroms kuyeretsa, kukonza nthawi yake mu valavu mkati ndi kunja komanso mu armature kuyamwa pamwamba mu dothi yotsalira, kupewa kuwonongeka kwa kusindikiza pamwamba.

Chachisanu ndi chiwiri, valavu ya solenoid mu ntchito yoyimitsa kutseka valavu pamaso pa valavu yamanja, kwa nthawi yaitali popanda valavu ya solenoid ndikuyambiranso nthawiyo, m'pofunika kuyang'ana motsatira ndondomeko, mu kusintha kwabwino mu kugwiritsa ntchito moyenera.
