Iphi ivalve yokukhulula ye-excavator

Ngaphezulu kwevalve yokukhupha, imilo efanayo. Uqale ujonge impompo yehydraulic engentla, uya kubona ukuba kukho imibhobho emibini enobungakanani obufanayo, iya kuba ngqindilili kuneminye imibhobho, le mibhobho mibini ikwivalve yokuhambisa, ivalve yokuhambisa ngaphezulu kwevalve yolawulo ehambelana nale mibhobho mibini. yivalve yokukhulula. I-valve yokunceda inefuthe eliqhubekayo lokunyuka koxinzelelo: kwi-quantitative pump throttling regulation system, ipompo yokulinganisa inika isantya sokuhamba rhoqo. Xa uxinzelelo lwenkqubo lukhula, imfuno yokuhamba iya kuncipha. Ngeli xesha, i-valve yokunceda ivuliwe, ukwenzela ukuba ukuhamba okugqithisiweyo kubuyele kwi-tank, ukuqinisekisa ukuba i-valve yokunceda i-inlet yoxinzelelo, oko kukuthi, uxinzelelo lokuphuma kwempompo luhlala luhlala (i-valve port ivame ukuvulwa ngokuguquguquka koxinzelelo) .

Indima yevalve yokunceda

Isiphumo seSpillover. I-valve ye-throttle inokulungelelanisa kwaye ilinganise ukuhamba kwisixhobo se-hydraulic xa ipompo yobungakanani inika ioli. Indima yokhuseleko lokhuseleko. Thintela iingozi ezibangelwa ngumthwalo ogqithisileyo wezixhobo zehydraulic kunye nezixhobo zoomatshini. Isetyenziswe njengevalve yokukhupha. Ivalve yokhuseleko lokulinga kunye ne-valve ye-solenoid eneendlela ezimbini zisetyenziswa kunye kwaye zingasetyenziswa njengenkqubo yokukhulula. Ulawulo olukude kunye neevalvu zokulawula uxinzelelo. Ulawulo oluphezulu noluphantsi lwezigaba ezininzi. Isetyenziswa njengevalve yolandelelwano.

Ukuba i-valve yokunceda ye-excavator yaphukile, iya kuchaphazela isenzo, kwaye uxinzelelo lwe-oyile alukwazi ukudluliselwa kwigumbi eliphezulu le-valve enkulu kunye negumbi langaphambili le-valve yokuqhuba, kwaye i-valve yomqhubi iya kulahlekelwa yimpembelelo yayo yokulawula. uxinzelelo lwevalve ephambili; Ngenxa yokuba akukho xinzelelo lwe-oyile kwigumbi eliphezulu le-valve ephambili kunye ne-spring force encinci kakhulu, i-valve eyintloko iba yi-valve yokunceda ngokuthe ngqo kunye ne-spring force encinci. Xa uxinzelelo lwegumbi lokungena kweoli liphantsi kakhulu, i-valve ephambili iya kuvula ukuphuphuma, kwaye inkqubo ayiyi kukwazi ukuseka uxinzelelo.
