Zofukula zowonjezera John Deere AT310587 proportional solenoid valve excavator

Kodi valavu yotsogolera ndi yoyendetsa ndege ndi yotani pamndandanda wa valve yotsogolera ya hydraulic proportional valve
Kuwongolera kwamafuta ndi kutulutsa kwa valavu yosinthira yachikhalidwe kumachitika kudzera pa spool, ndipo ubale wofananira pakati pa mipata iwiri yomvera pamadoko amafuta watsimikiziridwa kale momwe mapangidwe ndi kukonza kwa spool, ndipo ndizosatheka kusintha panthawiyi. gwiritsani ntchito, kotero kuti kutuluka kapena kupanikizika kudzera m'madoko awiri amafuta sangathe kuyendetsedwa paokha ndipo musakhudze wina ndi mzake.
Ndi kuchepa kwa mtengo wa microprocessing controller ndi sensor sensors ndikuwongolera mosalekeza kwaukadaulo wowongolera, ukadaulo wowongolera wapawiri-spool wagwiritsidwa ntchito pamakina omanga. Kampani yaku Britain ya Utronics imagwiritsa ntchito ukadaulo wake komanso maubwino a patent kupanga valavu yosinthira yamitundu iwiri, yomwe yakhala ikugwiritsidwa ntchito kwambiri ku JCB, Deere, DAWOO, CASE ndi makampani ena ofukula, magalimoto, zonyamula katundu ndi zofukula ndi zina. mankhwala. Kuti akwaniritse zofunikira zama hydraulic system pazinthu zamakina aku China. Ndi kuwongolera kosalekeza kwa kukhazikika komanso kuwongolera makina, zogulitsa za Utronics zalowa mumsika waku China munthawi yake, ndipo poyambilira zamaliza kutumiza zonyamula katundu za Xiagong (5t) ndi zofukula za Janyang (8t) ndikulowa muyeso.
1. Zowonongeka za valve yachikhalidwe ya single-spool directional valve
Dongosolo la hydraulic lomwe limapangidwa ndi valavu yachikhalidwe ya single-spool directional ndizovuta kuthetsa kutsutsana pakati pa ntchito ndi kuwongolera zotsatirazi:
(1) Pofuna kupititsa patsogolo kukhazikika kwa dongosolo ndi kuchepetsa kukhudzidwa kwa kusintha kwa katundu pa liwiro, makina a hydraulic amapangidwa kuti azipereka zina mwazinthu zomwe tikufuna kukwaniritsa, kapena kuwonjezera zigawo zina za hydraulic, monga ma valve oyendetsa liwiro, kulamulira kuthamanga. ma valve, ndi zina zotero. Koma kuwonjezera kwa zigawo zoterezi kudzachepetsa mphamvu ndi kuwononga mphamvu; Zidzachepetsanso kudalirika kwa dongosolo lonse ndikuwonjezera mtengo.
