Chowonjezera chofufutira cha 375-4414 Hydraulic valve

Zolakwika zomwe zimafala ndikuti valavu ya solenoid siigwira ntchito, yomwe iyenera kuyang'aniridwa kuchokera kuzinthu zotsatirazi:

1. Chojambulira cha valve cha solenoid ndi chotayirira kapena cholumikizira waya chazimitsidwa, valavu ya solenoid si yamagetsi, ndipo cholumikizira cha waya chikhoza kumangika.
2, koyilo ya solenoid yatenthedwa, mutha kuchotsa waya wa solenoid valve, muyeso ndi multimeter, ngati yotseguka, koyilo ya solenoid itenthedwa.Chifukwa chake ndi chakuti koyiloyo imakhala yonyowa, yomwe imayambitsa kutsekemera kosauka komanso kutuluka kwa maginito, kuchititsa kuti pakalipano mu coil ikhale yaikulu kwambiri ndikuwotchedwa, kotero ndikofunikira kuti mvula isalowe mu valve solenoid.Kuphatikiza apo, kasupe ndi wamphamvu kwambiri, mphamvu yochitira ndi yayikulu kwambiri, kutembenuka kwa koyilo kumakhala kochepa kwambiri, ndipo kuyamwa sikukwanira kungapangitsenso koyilo kuyaka.Pakachitika mwadzidzidzi, batani lamanja pa koyilo likhoza kukanidwa kuchokera pa "0" pamalo ogwirira ntchito wamba kupita ku "1" kuti valavu itseguke.
3, valavu ya solenoid yomatira: mawondo a solenoid valve ndi spool yokhala ndi chilolezo chaching'ono (zosakwana 0.008mm), nthawi zambiri imakhala imodzi.
Kuphatikizika kwa magawo, pakakhala zodetsa zamakina kapena mafuta opaka pang'ono, ndikosavuta kukakamira.Njira yochizira imatha kukhala waya wachitsulo kudzera pabowo laling'ono lamutu kuti libwererenso.Njira yothetsera vutoli ndikuchotsa valavu ya solenoid, kuchotsa manja a spool ndi spool, ndikutsuka ndi CCI4, kuti spool ikhale yosinthasintha mu manja a valve.Pamene disassembling, chidwi ayenera kuperekedwa kwa makonzedwe msonkhano ndi kunja mawaya malo a chigawo chilichonse, kuti asonkhanitse ndi waya molondola, ndi kuwona ngati bowo kutsitsi mafuta watsekedwa ndi ngati mafuta mafuta ndi okwanira.

Kuyendetsa ndi kosiyana.Chida choyendetsa cha valavu yofananira ndi ma elekitiroma wofananira, ndipo choyendetsa cha valavu ya servo ndi mota yamphamvu kapena torque mota, ndipo magawo amachitidwe ndi osiyana.Hysteresis, zone akufa pakati, bandiwifi, kusefera kulondola ndi makhalidwe ena ndi osiyana, kotero nthawi ntchito ndi osiyana, mavavu servo ndi servo proportional mavavu amagwiritsidwa ntchito kwambiri mu kachitidwe otsekeka kuzungulira, mavavu proportional za nyumba zina ntchito makamaka lotseguka kuzungulira. machitidwe owongolera ndi machitidwe otsekera othamanga.
Mphamvu yolowera ya valve yofananira ndi yayikulu, makamaka m'ma mazana a Ma mpaka 1 amp kapena kupitilira apo, ndipo mphamvu yolowera ya valve wamba ndi yayikulu.
Zing'onozing'ono, makamaka mu makumi a MA;Kuwongolera kulondola kwa valavu yofananira ndi yotsika pang'ono, hysteresis ndi yaikulu kuposa ya valavu ya servo, ndipo kuwongolera kulondola kwa valve wamba kumakhala kwakukulu, koma zofunikira za mafuta ndizokwera.
Zimamveka kuchokera pamapangidwe kuti spool ya valve yofanana imayendetsedwa ndi mphamvu yamagetsi ndi mphamvu ya hydraulic ndi mphamvu ya masika, pamene valavu wamba imayenderana ndi kuthamanga kwa hydraulic, kotero kuti valavu yofanana ilibe phindu poyendetsa kutuluka kwakukulu ndi kuthamanga kwakukulu.Pali mavavu ofananira zinthu zoyambira zotseguka, zomwe ziyenera kukhala chifukwa chake amatchedwa ma valve ofananira.
