Nthawi zambiri amatsekedwa ma electromagnetic directional valve SV08-22

Kulephera kwa valavu ya solenoid kudzakhudza mwachindunji zochita za valve yosinthira ndi valve yolamulira. Kulephera kofala ndikuti valavu ya solenoid sichita, choncho iyenera kufufuzidwa kuchokera kuzinthu zotsatirazi:

1. Ngati cholumikizira cha valve solenoid chili chotayirira kapena cholumikizira chikugwa, valavu ya solenoid ikhoza kukhala yopanda magetsi, koma cholumikizira chikhoza kulumikizidwa.

2. Ngati chingwe cha valve solenoid chatenthedwa, chotsani chingwe cha solenoid valve ndikuchiyeza ndi multimeter. Ngati dera lili lotseguka, valavu ya solenoid imawotchedwa. Chifukwa chake ndi chakuti koyiloyo imakhala yonyowa, yomwe imayambitsa kutsekemera kosauka komanso kutayikira kwa maginito, zomwe zimapangitsa kuti pakhale kuchulukirachulukira mu koyilo ndi kuyaka, kotero ndikofunikira kuti madzi amvula asalowe mu valavu ya solenoid. Kuonjezera apo, kasupe ndi wovuta kwambiri, mphamvu yochitirapo kanthu ndi yaikulu kwambiri, chiwerengero cha kutembenuka kwa koyilo ndi kochepa kwambiri, ndipo mphamvu yoyamwa sikwanira, zomwe zingayambitsenso kuti koyilo iwotche. Ngati chithandizo chadzidzidzi, batani lamanja pa koyilo likhoza kutembenuzidwa kuchoka pa "0" pakugwira ntchito bwino kupita ku "1" kuti mutsegule valve.

3. Valve ya solenoid imamatira: kuvomereza koyenera pakati pa thumba la spool ndi valavu ya valve ya solenoid ndi yaying'ono kwambiri (yosakwana 0.008mm), yomwe nthawi zambiri imasonkhanitsidwa mu chidutswa chimodzi. Pakakhala zodetsa zamakina kapena mafuta opaka pang'ono, zimakhala zosavuta kukakamira. Njira yochizira ingagwiritsidwe ntchito kubaya waya wachitsulo kuchokera pabowo laling'ono pamutu kuti abwererenso. Njira yothetsera vutoli ndikuchotsa valavu ya solenoid, kuchotsa valavu ndi manja a valve, ndikuyeretsa ndi CCI4 kuti valavu ikhale yosunthika mu manja a valve. Pamene disassembling, chidwi ayenera kuperekedwa pa msonkhano zinayendera ndi kunja mawaya malo a chigawo chilichonse, kuti agwirizane ndi waya molondola. Komanso, fufuzani ngati dzenje lopopera mafuta la chopopera mafuta latsekedwa komanso ngati mafuta opaka ndi okwanira.

4. Kutuluka kwa mpweya: Kuthamanga kwa mpweya kumayambitsa mpweya wosakwanira, zomwe zimapangitsa kuti zikhale zovuta kutsegula ndi kutseka valve yokakamiza. Chifukwa chake ndi chakuti gasket yosindikiza yawonongeka kapena valavu ya slide yavala, zomwe zimapangitsa kuti mpweya uzituluka m'mabowo angapo. Polimbana ndi kulephera kwa valve solenoid ya makina osinthira, tiyenera kusankha mpata woyenera kuti tithane nawo pamene valavu ya solenoid itatha. Ngati sichingagwiridwe mkati mwa kusiyana kosinthira, tikhoza kuyimitsa makina osinthira ndikuwongolera modekha.
