Uhlalutyo lokungaphumeleli kwevalve yoxinzelelo olulinganayo kunye nokupheliswa

Ngenxa yokuba ivalve yoxinzelelo olulinganayo isekelwe kuphela kwisiseko sevalve yoxinzelelo eqhelekileyo, isibambo somlawuli sitshintshwa yi-proportional electromagnet. Ngoko ke, iimpazamo ezahlukahlukeneyo eziveliswa yisivalo esiqhelekileyo soxinzelelo, esiza kuvelisa izizathu eziphosakeleyo kunye neendlela zokuphelisa ivalve yoxinzelelo oluqhelekileyo nazo zisebenza ngokupheleleyo kwivalve yoxinzelelo oluhambelanayo (njengevalve ehambelanayo yokunceda), enokuthi iphathwa ngereferensi. Ukwengeza:

① Uzibuthe olinganiselayo we-electromagnetic akukho ngoku, ukuze ukusilela kulawulo lwamandla ombane ngeli xesha kuhlalutywe ngokwalo mxholo ungentla "(1) womlinganiso we-electromagnetic fault". Xa ukusilela kokulawulwa kombane kusenzeka, unokuqala ujonge ixabiso langoku ngemitha yombane ukubona ukuba kukho ingxaki kulawulo lwesekethe ye-electromagnetic, okanye ingxaki nge-proportional electromagnet, okanye ingxaki ngenxalenye yevalve, ethi inokuba luphawu.

② Nangona umbane ojikelezayo kwi-electromagnetic ulinganisiweyo ulinganisiwe, kodwa uxinzelelo alunyuki konke konke, okanye uxinzelelo olufunekayo alufumaneki, phakathi kwe-proportional pilot pressure regulator (valve yokukhulula) kunye nevalve enkulu yokunceda, i-pilot manual regulator. yevalve yoncedo yokulingwa eqhelekileyo isagciniwe, edlala indima yesivalo sokhuseleko apha. Xa ivalve yokulawula uxinzelelo iphantsi kakhulu, nangona i-electromagnetic electromagnet ngokusebenzisa langoku ilinganisiwe, kodwa uxinzelelo alunyuki, ukuba i-valve set pressure iphantsi kakhulu, i-pilot flow isuka kwi-valve ibuyele kwitanki, ukuze uxinzelelo alufiki. Kule meko, i-valve yokumisela uxinzelelo kufuneka inyuswe malunga ne-1MPa kunoxinzelelo oluphezulu lomsebenzi wevalve.

(3) Umji oqukuqelayo kwi-electromagnetic ehambelanayo mkhulu kakhulu, kodwa uxinzelelo alukanyuki, okanye uxinzelelo olufunekayo alunakujongwa ngeli xesha ukuxhathisa kwekhoyili yemagnethi elinganayo, ukuba ingaphantsi kakhulu kunexabiso elichaziweyo, ngoko ke isiphaluka sangaphakathi sekhoyili ye-electromagnet yaphukile; Ukuba ukuchasana kwekhoyili ye-electromagnet kuqhelekile, ngoko uxhulumaniso kwi-amplifier yokulinganisa lufutshane-lujikelezo. Ngeli xesha, i-electromagnetic elinganayo kufuneka ithathelwe indawo, kwaye uxhulumaniso kufuneka ludibaniswe, okanye i-coil yokubuyisela kufuneka ifakwe.
