Indima yevalve yokunceda

I-1, impembelelo yoxinzelelo oluqhubekayo: kwi-quantitative pump throttling regulation system, ipompo yobungakanani inikeza ukuhamba rhoqo.Xa uxinzelelo lwenkqubo luyancitshiswa, imfuno yokuhamba iya kuncitshiswa.Ngeli xesha, i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okungaphezulu kubuyele kwi-tank, ukuqinisekisa ukuba i-valve yokungena yoxinzelelo, oko kukuthi, uxinzelelo lwe-pump outlet luhlala luhlala (i-valve port ivame ukuvulwa ngokuguquguquka koxinzelelo) .

I-2, impembelelo yokulawula uxinzelelo: i-valve yokunceda idibaniswe kwichungechunge kwipayipi yokubuyisela, i-valve yokukhulula yenza uxinzelelo lwangasemva, kunye neendawo ezihambayo ziphucula i-flatness.

Isenzo sokuthambekela kwenkqubo: izibuko elikude levalve yokukhulula liqhagamshelwe kwivalve yesolenoid enendawo encinci yokuphuphuma.Xa inethiwekhi ye-electromagnetic inikwe amandla, i-remote control port yevalve yokunceda idlula itanki yamafutha, kwaye impompo ye-hydraulic ibuyiselwe umva okwangoku.Ivalve yokukhulula ngoku isetyenziswa njengevalve yokubuyela umva.

I-3, ukhuseleko lokhuseleko: Xa inkqubo isebenza ngokuqhelekileyo, i-valve yebhola icinyiwe.Kuphela xa umthwalo udlula umda ochaziweyo (uxinzelelo lwenkqubo ludlula uxinzelelo lokumisela), ukugqithiswa kuvuliwe ekukhuselweni kwelahleko yesigaba, ukwenzela ukuba uxinzelelo lwenkqubo alusayi kwandiswa (ngokubanzi, uxinzelelo lokumisela i-valve yokunceda i-10% ukuya I-20% ephezulu kunoxinzelelo oluphezulu lomsebenzi wenkqubo).

I-4, isicelo esisebenzayo ngokuqhelekileyo: njenge-valve yokubuyisela umva, njengomlawuli woxinzelelo olude, njenge-valve yokulawula i-multistage ephezulu kunye nephantsi, njenge-valve yokulandelelana, efanelekileyo ekubunjweni koxinzelelo lwangasemva (umtya kumbhobho wokubuyisela).

Ivalve yokukhulula idla ngokuba nezakhiwo ezibini: 1, ivelufa esebenza ngokuthe ngqo.2. Isivalo soncedo esilingwayo esisebenzayo.

Iimfuno eziphambili zevalve yokukhulula zezi: uluhlu olukhulu lokulawula uxinzelelo, impazamo yokulawula uxinzelelo oluncinci, i-oscillation encinci yoxinzelelo, isenzo esibuthathaka, amandla okulahleka kwesigaba esikhulu, kunye nengxolo encinci.

Umgaqo wokusebenza wevalve yokunceda

Ivalve yokunceda luhlobo lwevalve yokulawula uxinzelelo lweoyile, eyona nto idlala indima yokuphuphuma koxinzelelo rhoqo, ukulawulwa koxinzelelo, ukuguqulwa kwenkqubo kunye nokukhuselwa kokhuseleko kwizixhobo zoxinzelelo lweoyile.

Umgaqo wevalve yokunceda: Kwinkqubo yokulawula ipompo yokulinganisa, ipompo yobungakanani ibonelela ngesantya sokuhamba rhoqo, kwaye xa uxinzelelo lwenkqubo luncitshisiwe, imfuno yokuhamba iya kuncitshiswa.Okwangoku, i-valve yokunceda ivula i-valve yokulawula uxinzelelo kunye nokunciphisa i-valve ukwenza ukuhamba okugqithisileyo kubuyele kwi-tank kunye nokuqinisekisa ukunyanzeliswa kwe-inlet yevalve yokunceda.

Kwi-fixed pump throttling control system, ipompo esisigxina inikeza ukuhamba rhoqo.Xa uxinzelelo lwenkqubo luyancitshiswa, imfuno yokuhamba iya kuncitshiswa.Okwangoku, i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okugqithisiweyo kubuyele kwi-tank yokulawula uxinzelelo kunye ne-valve yokunciphisa uxinzelelo, ukuqinisekisa ukuba i-valve yokungena yoxinzelelo, oko kukuthi, uxinzelelo lokuphuma kwempompo luhlala luhleli (i-valve port i- ihlala ivulwa ngokuguquguquka koxinzelelo).
