Oyenera E320 330 336GC proportional solenoid valavu 585-9231 excavator Chalk

Kodi proportional valve imagwira ntchito bwanji?

Ulamuliro wodziwikiratu ukhoza kugawidwa kukhala kuwongolera kwapakatikati ndi kuwongolera kosalekeza. Kuwongolera kwakanthawi ndikuwongolera kosintha. Mu makina oyendetsa ma pneumatic, ON-OFF valve reversing valve yokhala ndi maulendo otsika ogwiritsira ntchito amagwiritsidwa ntchito kuti azitha kuyendetsa gasi. Dalirani valavu yochepetsera kupanikizika kuti musinthe kupanikizika kofunikira, kudalira valavu ya throttle kuti musinthe kayendedwe kake. Dongosolo lamakono lowongolera chibayo likufuna kukhala ndi mphamvu zingapo zotulutsa komanso kuthamanga koyenda kangapo, limafunikira ma valve ochepetsa kupanikizika kangapo, ma throttle valves ndi ma valve obwerera kumbuyo. Mwa njira iyi, osati zigawo zokha zomwe zimafunikira zambiri, mtengo wake ndi wokwera, kapangidwe kake kameneka ndi kovuta, ndipo zigawo zambiri ziyenera kusinthidwa pasadakhale. Kuwongolera kwamagetsi kwamagetsi kumayendetsedwa ndi kuwongolera kosalekeza, komwe kumadziwika ndi kusintha kwa kuchuluka kwa zotulutsa (mtengo wapano kapena mtengo wamagetsi), ndipo pali ubale wina wofananira pakati pa zomwe zimatuluka ndi kuchuluka kwake. Kuwongolera molingana kumatha kugawidwa kukhala kuwongolera kotseguka komanso kuwongolera kotseka. Kuwongolera kotsekeka kwa dongosolo la mayankho azizindikiro. 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. . Kusankha ndi kusonkhanitsa ma valve amagetsi, R & D ndikupanga ma valve a cartridge proportional valve ndi ma valve ogwirizana a multiway valve amaganizira mozama za kugwiritsa ntchito makina omanga, ndi kuwongolera oyendetsa, kuzindikira katundu ndi ntchito zolipirira kukakamizidwa. Ndikofunikira kwambiri kukonza luso lonse lamakina amtundu wa hydraulic. Makamaka, oyendetsa ndege oyendetsa ndege, kuwongolera kwakutali opanda zingwe ndi ma waya akutali awonetsa chiyembekezo chabwino chogwiritsa ntchito. Mfundo: Chizindikiro cholowera chikuwonjezeka, mpweya woyendetsa mpweya wa solenoid valve woyendetsa ndege 1 umabwerera, ndipo mpweya wothamanga wa solenoid woyendetsa ndege 7 uli mu malo obwezeretsedwa, ndiye kuti mpweya wothamanga umalowa mu chipinda choyendetsa 5 kuchokera ku doko la SUP kupyolera mu valve 1, kupanikizika. Kukwera kwa chipinda choyendetsa ndege kukukwera, kuthamanga kwa mpweya kumtunda kwa diaphragm 2, ndiye valavu yamagetsi 4 yolumikizidwa ndi diaphragm 2 imatsegulidwa, valavu yotulutsa mpweya 3 imatsekedwa, ndipo mphamvu yotulutsa mpweya imapangidwa. Kuthamanga kotulutsaku kumabwezeretsedwanso kulamulira loop 8 kupyolera mu mphamvu ya sensor 6. Apa, kufananitsa mwamsanga kumapangidwa ndi mtengo wamtengo wapatali mpaka kutulutsa mphamvu kumakhala kofanana ndi chizindikiro cholowera, zomwe zimapangitsa kusintha kwa mphamvu yotulutsa mphamvu yofanana ndi kusintha. chizindikiro cholowera. Chifukwa palibe makina otsekemera a nozzle, valavu simamva zonyansa ndipo imakhala yodalirika kwambiri.
