Izixhobo zoomatshini bokwakha EHPR08-33 ivalve yekhatriji enemisonto

Uhlalutyo lokungaphumeleli kwevalve yoxinzelelo olulinganayo kunye nokupheliswa

Umji oqukuqelayo we-electromagnetic we-proportional electromagnet umkhulu kakhulu, kodwa uxinzelelo alukabikho phezulu, okanye uxinzelelo olufunekayo alukwazi ukujongwa ngeli xesha ukuxhathisa i-coil ye-proportional electromagnet, ukuba ingaphantsi kwexabiso elichaziweyo, ngoko ke isekethe yangaphakathi. yekhoyili ye-electromagnetic 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.

Xa inyathelo loxinzelelo litshintsha, ukuguquguquka koxinzelelo lwe-amplitude encinci ihlala ihlala njalo, kwaye isizathu sokungazinzi koxinzelelo olubekiweyo kukuba kukho ukungcola okuncanyathiselwe phakathi kombindi we-electromagnetic part kunye nesikhokelo (umkhono wesikhokelo), esithintela. intshukumo yondoqo. Ukongezelela, inxalenye ye-sliding ye-spool ephambili ibanjwe ngokungcola, okuthintela ukuhamba kwe-spool ephambili. Ngenxa yemiphumo yolu kungcola, i-hysteresis iyanda. Kwinqanaba le-hysteresis, uxinzelelo aluzinzile kwaye uxinzelelo luguquguquka rhoqo. Esinye isizathu kukuba ukunxiba kwentsimbi yentsimbi kunye nesibini somkhono wemagnethi, i-gap iyanda, kwaye uxinzelelo olulungisiweyo (ngexabiso elithile langoku) alizinzile.

Ngeli xesha, i-valve kunye ne-electromagnetic elinganayo inokuchithwa ukuze ihlambuluke, kwaye ukungcola kweoli ye-hydraulic kunokujongwa. Ukuba idlula imimiselo, ioli kufuneka itshintshwe; Ukukhutshwa okugqithisileyo okubangelwa ukunxitywa kwentsimbi yentsimbi, okukhokelela ekwandeni kwe-hysteresis yamandla, okubangela ukulawulwa koxinzelelo olungazinzanga, ububanzi obungaphandle bombindi wentsimbi kufuneka kwandiswe ukuze kugcinwe ukuhambelana kakuhle nomkhono wesikhokelo.

Impendulo yoxinzelelo iyacotha kwaye uxinzelelo lutshintsha ngokucothayo ngenxa yokuba umoya okwi-electromagnetic magnethi awukhutshwa ucocekile; I-orifice esisigxina kunye ne-valve orifice engundoqo (okanye i-bypass orifice) yokumanzisa kwi-electromagnetic orifice ivalwe bumdaka, kwaye ukuhamba kwe-proportional ye-electromagnetic core kunye ne-core valve core kuthintelwe ngokungeyomfuneko; Ukongezelela, umoya ungeniswa kwinkqubo, edla ngokuphindaphindiweyo xa izixhobo zisanda kufakwa kwaye ziqala ukusebenza okanye xa umoya uxutywe emva kokuvala ixesha elide.
