Ma valve a hydraulic solenoidamagwiritsidwa ntchito kwambiri pakupanga kwathu.Ndiwo zigawo zowongolera mu hydraulic system.Muyenera kuti mwawona mavuto ambiri okhudzana ndi ma valve a solenoid ndikuthana ndi zolakwika zosiyanasiyana.
Muyenera kuti mwasonkhanitsa zambiri zofunikira.Solenoid valve troubleshooting experience, lero Dalan hydraulic system wopanga adzakufotokozerani valve solenoid yomwe imagwiritsidwa ntchito mu hydraulic system.
Tiyeni tikhale ndi chidziwitso choyambirira cha valavu ya solenoid.Valavu ya solenoid imapangidwa ndi koyilo ya solenoid ndi maginito, ndipo ndi thupi la valve lomwe lili ndi mabowo amodzi kapena angapo.
Pamene koyiloyo ipatsidwa mphamvu kapena kuchotsedwa mphamvu, kugwira ntchito kwa maginito kumapangitsa kuti madziwo adutse mu thupi la valve kapena kudulidwa, kuti akwaniritse cholinga chosintha njira yamadzimadzi.
Zigawo za electromagnetic za valve solenoid zimapangidwa ndi chitsulo chokhazikika, chitsulo chosuntha, koyilo ndi zina;gawo la thupi la valavu limapangidwa ndi spool valve core, manja a spool valve,
maziko a masika ndi zina zotero.Chophimba cha solenoid chimayikidwa mwachindunji pa thupi la valve, lomwe limatsekeredwa mu gland, ndikupanga kuphatikiza kwabwino komanso kophatikizana.
Ma valve a solenoid omwe amagwiritsidwa ntchito kwambiri pakupanga kwathu amaphatikizapo malo awiri a njira zitatu, malo awiri-njira zinayi, malo awiri-njira zisanu, ndi zina zotero.
imakhala ndi magetsi komanso yopanda mphamvu, ndipo valavu yoyendetsedwa imayatsidwa ndi kuzimitsa.
Mu dongosolo lolamulira zida za jenereta yathu ya okosijeni, valavu ya solenoid yokhala ndi magawo awiri ndi yomwe imagwiritsidwa ntchito kwambiri.Itha kugwiritsidwa ntchito kuyatsa kapena kuzimitsa gasi popanga,
kuti musinthe njira ya gasi ya mutu wa pneumatic control membrane.Zimapangidwa ndi thupi la valve, chivundikiro cha valve, msonkhano wa electromagnetic, masika ndi mawonekedwe osindikizira ndi zina.
Chosindikizira chomwe chili pansi pa chitsulo chosuntha chimatseka mpweya wolowera m'thupi la valve ndi kuthamanga kwa kasupe.Pambuyo pamagetsi, ma elekitiromagineti amatsekedwa,
ndipo chipika chosindikizira chokhala ndi kasupe kumtunda kwa chitsulo chosuntha chimatseka doko lotulutsa mpweya, ndipo kutuluka kwa mpweya kumalowa mumutu wa nembanemba kuchokera ku mpweya wolowera kuti mugwire ntchito yolamulira.Mphamvu ikatha,
mphamvu yamagetsi imasowa, chitsulo chosuntha chimachoka pachimake chachitsulo chokhazikika pansi pa mphamvu ya masika, chimayenda pansi, chimatsegula doko lotulutsa mpweya, chimatsekereza mpweya,
mpweya wa mutu wa nembanemba umatuluka kudzera pa doko lotayirira, ndipo diaphragm imachira.malo oyamba.Pazida zathu zopangira oxygen, zimagwiritsidwa ntchito podula mwadzidzidzi
valavu yoyang'anira membrane polowera kwa turbo expander, etc.
Valve yanjira zinayi ya solenoid imagwiritsidwanso ntchito kwambiri pakupanga kwathu, ndipo mfundo yake yogwira ntchito ndi iyi:
Panopa ikadutsa pa koyilo, chiwopsezo chimapangidwa, ndipo chitsulo chokhazikika chimakopa pachimake chitsulo, ndipo chitsulo chosuntha chimayendetsa pakati pa spool valve ndi
compresses kasupe, kusintha malo a spool valavu pachimake, potero kusintha njira ya madzimadzi.Pamene koyiloyo yachotsedwa mphamvu, slide valve core idzakankhidwa molingana
ku mphamvu yotanuka ya * kasupe, ndipo chitsulo chachitsulo chidzakankhidwira mmbuyo kuti madzi aziyenda mbali yoyambirira.Pakupanga kwathu kwa okosijeni, kusintha kwa valve yokakamiza ya ma molekyulu
Sieve switching system imayang'aniridwa ndi valavu yanjira zinayi ya solenoid, ndipo kutuluka kwa mpweya kumaperekedwa kumalekezero onse a pistoni ya valavu yokakamiza.Kulamulira kutsegula ndi
kutseka kwa valve yokakamiza.Kulephera kwa valavu ya solenoid kudzakhudza mwachindunji zochita za valve yosinthira ndi valve yolamulira.Kulephera kofala ndikuti valavu ya solenoid siigwira ntchito.
Iyenera kufufuzidwa kuchokera kuzinthu zotsatirazi:
(1) Chotsekera cha valve ya solenoid ndi chotayirira kapena ulusi umatha kugwa, valavu ya solenoid ilibe mphamvu, ndipo ulusi ukhoza kumangika.
(2) Chophimba cha valve cha solenoid chatenthedwa.Wiring wa valavu solenoid akhoza kuchotsedwa ndi kuyeza ndi multimeter.Ngati dera lotseguka, valavu ya solenoid imawotchedwa.
Chifukwa chake ndi chakuti koyiloyo imakhudzidwa ndi chinyontho, zomwe zingayambitse kutsekeka kosakwanira komanso kutuluka kwa maginito, zomwe zingayambitse kuchulukirachulukira mu koyilo ndikuwotchedwa.
Choncho, madzi amvula ayenera kutetezedwa kuti asalowe mu valve solenoid.Kuphatikiza apo, kasupe ndi wovuta kwambiri, mphamvu yochitira ndi yayikulu kwambiri, kuchuluka kwa kutembenuka kwa koyilo kumakhala kochepa kwambiri,
ndipo mphamvu yoyamwa sikwanira, zomwe zingapangitsenso kuti koyiloyo ipse.Pochiza mwadzidzidzi, batani lamanja pa koyilo litha kusinthidwa kuchoka ku "0" kupita ku "1" panthawi yanthawi zonse kuti mutsegule valavu.
(3) Valavu ya solenoid yakhazikika.Kusiyana kwa mgwirizano pakati pa valavu ya slide ndi nsonga ya valve ya solenoid ndi yaying'ono kwambiri (yosakwana 0.008mm), ndipo nthawi zambiri imasonkhanitsidwa mu chidutswa chimodzi.
Pamene zonyansa zamakina zibweretsedwa kapena mafuta opaka mafuta achepa kwambiri, amamira mosavuta.Njira yochizira ndiyo kugwiritsa ntchito waya wachitsulo pobowola kabowo kakang'ono m'mutu kuti ibwererenso.
Njira yothetsera vutoli ndikuchotsa valavu ya solenoid, kuchotsa valavu ndi manja a valve, ndikuyeretsa ndi CCI4 kuti valavu ikhale yosunthika mu manja a valve.Pakusweka,
tcherani khutu ku mndandanda wamagulu a zigawozo ndi malo a waya wakunja, kuti kugwirizanitsanso ndi waya ndizolondola, ndipo fufuzani ngati bowo lopopera mafuta la lubricator latsekedwa.
komanso ngati mafuta opaka ndi okwanira.
(4) Kutayikira.Kutuluka kwa mpweya kumayambitsa kuthamanga kwa mpweya kosakwanira, zomwe zimapangitsa kuti zikhale zovuta kutsegula ndi kutseka valve yokakamiza.Chifukwa chake ndikuti gasket yosindikizira yawonongeka kapena valavu ya slide yavala,
kuchititsa mpweya kuwomba m'mabowo angapo.Pochita ndi vuto la solenoid valve ya makina osinthira, nthawi yoyenera iyenera kusankhidwa, ndipo valavu ya solenoid iyenera kukhala.
anathana ndi mphamvu ikatha.Ngati kukonza sikungatheke mkati mwa kusiyana kosinthira, makina osinthira amatha kuyimitsidwa ndikugwiridwa modekha.
