Proportional pressure valve failure kusanthula ndi kuthetsa

Panopa ikuyenda molingana ndi maginito amagetsi ndi yayikulu kwambiri, koma kupanikizika sikunapitebe, kapena kuthamanga kofunikira sikungayang'anenso panthawiyi kukana kwa koyilo yamagetsi ofananirako, ngati ocheperako kuposa mtengo womwe watchulidwa, ndiye kuti dera lamkati koyilo ya electromagnet yasweka; Ngati kukana kwa koyilo ya electromagnet kuli kwabwinobwino, ndiye kuti kulumikizana ndi amplifier yofananira kumakhala kozungulira. Panthawiyi, ma electromagnet oyenerera ayenera kusinthidwa, ndipo kugwirizanako kuyenera kulumikizidwa, kapena kuyikanso koyilo yobwezeretsanso.

Pamene kuthamanga sitepe kusintha, kuthamanga kusinthasintha kwa matalikidwe ang'onoang'ono ndi nthawi zonse, ndipo chifukwa kusakhazikika kwa kuthamanga anapereka makamaka kuti pali dothi Ufumuyo pakati pa pachimake cha proportional maginito electromagnetic ndi kutsogolera gawo (chiwongolero manja), amene amalepheretsa kuyenda kwapakati. Kuonjezera apo, mbali yotsetsereka ya spool yaikulu imakhala ndi dothi, zomwe zimalepheretsa kuyenda kwa spool yaikulu. Chifukwa cha zotsatira za zonyansazi, hysteresis imawonjezeka. Pakukula kwa hysteresis, kupanikizika sikukhazikika ndipo kupanikizika kumasinthasintha nthawi zonse. Chifukwa china ndi chakuti kuvala kwachitsulo chachitsulo ndi maginito awiri a maginito, kusiyana kumawonjezeka, ndipo kupanikizika kosinthika (kupyolera mumtengo wina wamakono) sikukhazikika.

Panthawiyi, valavu ndi maginito ofananirako amatha kuchotsedwa kuti ayeretsedwe, ndipo kuipitsidwa kwa mafuta a hydraulic kungafufuzidwe. Ngati idutsa malamulo, mafutawo ayenera kusinthidwa; Pachilolezo chochuluka chifukwa cha kuvala kwa chitsulo pakati, zomwe zimapangitsa kuwonjezeka kwa mphamvu ya hysteresis, zomwe zimapangitsa kuti pakhale kusasunthika kwa kayendetsedwe kake, chigawo chakunja chachitsulo chiyenera kuwonjezeka kuti chigwirizane bwino ndi manja owongolera.

Kuthamanga kwamphamvu kumakhala kwaulesi ndipo kuthamanga kumasintha pang'onopang'ono chifukwa mpweya wamagetsi ofananirako sumatulutsidwa woyera; The orifice orifice ndi main vavu orifice (kapena bypass orifice) kwa damping pa electromagnet pachimake watsekedwa dothi, ndi kayendedwe ka proportional electromagnet pachimake ndi valavu pachimake chachikulu amalephereka mosafunikira; Kuonjezera apo, mpweya umalowetsedwa mu dongosolo, zomwe nthawi zambiri zimachitika pamene zipangizo zangoikidwa kumene ndikuyamba kugwira ntchito kapena pamene mpweya umasakanikirana pambuyo pa kutsekedwa kwa nthawi yaitali.
