Chofukula cha hydraulic pump solenoid valve proportional solenoid valve TM68301

Proportional valavu, valavu otaya ulamuliro akhoza kugawidwa mu mitundu iwiri. Imodzi ndikuwongolera kosinthana, ina ndikuwongolera mosalekeza, valavu ya servo ndi ma valve ena ndi osiyana, kutayika kwake kwamphamvu kumakhala kwakukulu, chifukwa kumafunika kuyenda kwina kuti kusungitse ntchito ya dera loyang'anira mafuta. 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.

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 kwa ma valve amagetsi ndi gawo la kuwongolera kosalekeza, komwe kumadziwika ndi kusintha kwa kuchuluka kwa zotulutsa ndi kuchuluka kwa zolowetsa, ndipo pali ubale wina wofananira pakati pa kuchuluka kwa zotulutsa ndi kuchuluka kwa zolowetsa. Proportional control ili ndi loop yotseguka Kusiyana pakati pa kuwongolera ndi kuwongolera kotseka.
