Excavator koyilo Hydraulic koyilo solenoid valavu koyilo dzenje 17.6mm kutalika 40mm

Ntchito ya coil ya Excavator

Valavu ya solenoid imapangidwa ndi koyilo yamagetsi ndi maginito, ndipo ndi thupi la valve lomwe lili ndi mabowo amodzi kapena angapo.Koyiloyo ikayatsidwa kapena kuzimitsidwa, kugwira ntchito kwa maginito kumapangitsa kuti madziwo adutse m'thupi la valve kapena kudulidwa kuti akwaniritse cholinga chosinthira njira yamadzimadzi.Magawo a electromagnetic a valve solenoid amapangidwa ndi chitsulo chokhazikika, chitsulo chosuntha, koyilo ndi zinthu zina;Gawo la thupi la valve limapangidwa ndi spool, spool sleeve, maziko a kasupe, etc. Solenoid imayikidwa mwachindunji pa thupi la valve, lomwe limayikidwa mu chubu losindikizidwa, kupanga chosavuta komanso chophatikizika.Zomwe timagwiritsa ntchito popanga ma valve solenoid tili ndi njira ziwiri zitatu, ziwiri zinayi, ziwiri zanjira zisanu ndi zina zotero.Pano pali tanthawuzo la awiri oyambirira: chifukwa valavu ya solenoid imayendetsedwa ndi kutaya mphamvu, chifukwa valavu yoyendetsedwa ndi yotseguka ndi yotseka.

Pali mitundu yambiri ya mavavu a solenoid, pali gasi wowongolera, madzi (monga mafuta, madzi), ambiri aiwo ndi msampha wa waya pa valavu, amatha kupatulidwa, spool imapangidwa ndi zinthu za ferromagnetic, zomwe mphamvu yamaginito opangidwa pamene koyilo yapatsidwa mphamvu imakopa spool, ndipo valavu imayendetsedwa ndi spool kuti itsegule kapena kutseka.Koyiloyo imatha kuchotsedwa padera.Valavu ya solenoid imagwiritsidwa ntchito kuwongolera kutsegula kapena kutseka kwa payipi ya gasi.Pachimake chosunthika mu koyilo ya valavu ya solenoid imakopeka ndi koyilo pomwe valavu ili ndi mphamvu, ndipo imayendetsa spool kuti isunthe kuti isinthe mawonekedwe a valve.

Mapangidwe a valavu ya solenoid amapangidwa ndi coil yamagetsi ndi maginito, ndipo ndi thupi la valve lomwe lili ndi bowo limodzi kapena angapo.Pamene koyiloyo ipatsidwa mphamvu kapena kuchotsedwa mphamvu, kugwira ntchito kwa maginito kumapangitsa kuti madziwo adutse mu thupi la valve kapena kudulidwa, kuti asinthe njira yamadzimadzi.Kuwotcha kwa valavu ya solenoid kumayambitsa kulephera kwa valve ya solenoid, ndipo kulephera kwa valavu ya solenoid kudzakhudza mwachindunji kusintha kwa valve ndi valavu yoyendetsa.Kodi ndi zifukwa ziti zomwe zimawotchera valavu ya solenoid?Chimodzi mwazifukwa zake ndikuti koyiloyo ikanyowa, kutayikira kwa maginito kumachitika chifukwa cha kusakhazikika kwake, zomwe zimapangitsa kuti koyiloyo ikhale yochulukirapo komanso kuyaka.Choncho, chidwi chiyenera kuperekedwa kuti mvula isalowe mu valve ya solenoid.Kuphatikiza apo, kasupe ndi wovuta kwambiri, zomwe zimapangitsa kuti pakhale mphamvu yochulukirapo, kutembenuka kwa ma coil ochepa komanso kusayamwa kokwanira, zomwe zingapangitse kuti koyilo ya valve ya solenoid iyake.
