Ifanele izesekeli ze-excavator J05E SK350-8 valve solenoid 94200-1221

I-Electrohydraulic proportional multiway valve load sensing kanye nobuchwepheshe besinxephezelo sengcindezi

Yonga amandla, wehlise izinga lokushisa likawoyela futhi uthuthukise ukunemba kokulawula, kodwa futhi wenze isenzo esivumelanayo ukunyakaza kwe-actuator okuningana kungaphazamisi omunye nomunye, manje imishini yokwakha ethuthuke kakhulu isebenzisa inzwa yomthwalo kanye nobuchwepheshe besinxephezelo sengcindezi.Inzwa yomthwalo kanye nesinxephezelo sokucindezela kuwumqondo ofana kakhulu, kokubili okusebenzisa izinguquko zomthwalo ukuze kubangele izinguquko zengcindezi ukuze kulungiswe umfutho wephampu noma we-valve nokugeleza ukuze uvumelane nezidingo zesistimu.Inzwa yokulayisha yamaphampu omthamo
Ngokwesistimu, umjikelezo we-oyela wokuzwa ukucindezela komthwalo wemithwalo uholelwa ku-valve yokulawula ingcindezi ekude, lapho umthwalo umncane, ukucindezela kokubeka i-valve yokusiza nakho kuncane;Umthwalo mkhulu, ingcindezi yokubeka nayo inkulu, kodwa kuhlale kunokulahlekelwa okuthile okuchichimayo.Uhlelo lwephampu oluguquguqukayo luwumjikelezo kawoyela ozwa umthwalo ongeniswa kumshini oguquguqukayo wepompo, ukuze ingcindezi yokuphuma kwephampu inyuke ngokucindezela komthwalo (umehluko omncane omisiwe wengcindezi njalo), ukuze ukuphuma kwepompo kugeleze futhiIzidingo zangempela zesistimu ziyalingana, akukho ukulahlekelwa ukuchichima, futhi ukonga amandla kuyenziwa.
 

Isinxephezelo sokucindezela siyisilinganiso sokuqinisekisa sokuthuthukisa ukusebenza kokulawula ama-valve.Ingcindezi yomthwalo engemuva kwembobo ye-valve yethulwa ku-valve yesinxephezelo sokucindezela, futhi i-valve yesinxephezelo sokucindezela ilungisa ingcindezi phambi kwembobo ye-valve ukuze umehluko wengcindezi phakathi kwengaphambili nangemuva kwembobo ye-valve uhlale njalo, ukuze ukugeleza. isici sokulawula se-throttle port sinokugeleza okukhulu ngembobo ye-valve
Okuncane kuhlobene kuphela nokuvulwa kwe-valve port, futhi akuthintwa ukucindezela komthwalo.
