393000M024 Excavator hydraulic pump solenoid valve proportional solenoid valve 3768317

Kusiyana pakati pa valavu yamagetsi yamagetsi ndi valavu ya solenoid

Kuwongolera kwa ma valve kumatha kugawidwa m'mitundu iwiri:
 

Imodzi ndi kusintha kosintha: mwina kutseguka kwathunthu kapena kutsekedwa kwathunthu, kuthamanga kwake kumakhala kokwanira kapena kocheperako, palibe gawo lapakati, monga ma elekitirodi wamba kudzera mu valavu, valavu yosinthira ma elekitirodi, valavu yosinthira ma elekitirodi hayidiroliki. Zina ndikuwongolera mosalekeza: doko la valve likhoza kutsegulidwa malinga ndi kufunikira kwa digiri iliyonse yotsegulira, potero kulamulira kukula kwa kutuluka, ma valve oterowo ali ndi ulamuliro pamanja, monga ma throttle valves, komanso amawongoleredwa pakompyuta, monga molingana. ma valve, ma servo valves. Chifukwa chake cholinga chogwiritsa ntchito valavu yofananira kapena valavu ya servo ndi: kukwaniritsa kuwongolera koyenda ndi kuwongolera zamagetsi (zowona, pambuyo pakusintha kwadongosolo kungathenso kuwongolera kuthamanga, etc.), popeza ndikuwongolera, payenera kukhala kutaya mphamvu, servo. valavu ndi ma valve ena ndi osiyana, kutaya mphamvu zake kumakhala kwakukulu, chifukwa kumafunika kuyenda kwina kuti kusungitse ntchito ya pre-siteji control mafuta dera.
Electromagnetic valve (Electromagnetic valve) ndi ntchito yamagetsi yamagetsi

Mfundo yogwira ntchito ya proportional solenoid valve
   

Electro-hydraulic proportional valve ndi chizindikiro chofananira chamagetsi amagetsi amagetsi mu valavu kuti apange chofananira, kuti valavu yogwira ntchito isunthike, kusintha kukula kwa doko la valve ndikumaliza kukakamiza ndi kutulutsa zomwe zimatulutsa molingana ndi voteji yolowera. Kusamuka kwa Spool kumatha kudyetsedwanso ndi makina, ma hydraulically kapena magetsi. Electro-hydraulic proportional valve ili ndi mitundu yosiyanasiyana, yosavuta kugwiritsa ntchito magetsi ndi makompyuta pamakina osiyanasiyana a electro-hydraulic, kulondola kwapamwamba, kusinthika kosinthika ndikugwiritsa ntchito, komanso mphamvu zotsutsana ndi kuipitsidwa, ndi zabwino zina, malo ogwiritsira ntchito akukulirakulira. . M'zaka zaposachedwa, kakulidwe ndi kupanga ma plug-in proportional valves ndi proportional multiway mavavu amaganizira bwino za mawonekedwe a makina omangira, owongolera oyendetsa, ozindikira katundu ndi ntchito zolipirira kukakamizidwa. Ndikofunikira kwambiri kukonza luso lonse lamakina amtundu wa hydraulic.
