TM90502 excavator hydraulic impompo ivelufa proportional solenoid

Itekhnoloji yembuyekezo yomthwalo kunye noxinzelelo lwe-electro-hydraulic proportional multiway valve

Ukugcina amandla, ukunciphisa ubushushu be-oyile kunye nokuphucula ukuchaneka kolawulo, kunye nokwenza izinto ezininzi zesigqeba zesenzo esihambelanayo zingaphazamisi omnye komnye xa ushukuma, oomatshini bokwakha abakumgangatho ophezulu ngoku basebenzisa ukuva umthwalo kunye netekhnoloji yembuyekezo yoxinzelelo. Ukuvakalelwa komthwalo kunye nembuyekezo yoxinzelelo yingcamango efanayo kakhulu, zombini zisebenzisa utshintsho loxinzelelo olubangelwa ukutshintshwa komthwalo ukulungelelanisa uxinzelelo kunye nokuhamba kwempompo okanye i-valve ukulungelelanisa iimfuno zokusebenza kwenkqubo. Ukuvalelwa komthwalo wenkqubo yempompo yobungakanani kukukhokela uxinzelelo lomthwalo ngesekethe ye-oyile yokuva umthwalo ukuya kwivalvu yokukhulula yolawulo loxinzelelo olude. Xa umthwalo uncinci, i-valve yokumisela uxinzelelo incinci. Umthwalo mkhulu, uxinzelelo lokumisela nalo lukhulu, kodwa kuhlala kukho ilahleko ethile yokuphuphuma. Kwinkqubo yempompo eguquguqukayo, isiphaluka se-oyile esivayo umthwalo singeniswa kwindlela eguquguqukayo yempompo, ukuze uxinzelelo lwempompo lunyuke ngokunyuka koxinzelelo lomthwalo (usoloko kukho umahluko omncinci osisigxina), ukuze imveliso iphume. ukuhamba kwempompo kufana nokuhamba kwangempela kwenkqubo, ngaphandle kokulahlekelwa kokuphuphuma, kunye nokugcinwa kwamandla kuyenzeka.

Imbuyekezo yoxinzelelo ngumlinganiselo wesiqinisekiso sokuphucula ukusebenza kolawulo lwevalve. Uxinzelelo lomthwalo emva kokuba i-valve port ifakwe kwivalve yembuyekezo yoxinzelelo, kwaye ivalve yembuyekezo yoxinzelelo ilungelelanisa uxinzelelo phambi kwe-valve port ukuze umahluko woxinzelelo ngaphambi nangemva kwe-valve port ungaguquki, ukuze ukuhamba ngevalve. izibuko ngokweempawu zolawulo lokuhamba kwe-throttle port inxulumene kuphela nokuvulwa kwe-valve port, kwaye ayichatshazelwa luxinzelelo lomthwalo.
