Izincedisi ze-Komatsu excavator PC120-6 ivalve yokucima ivalve yokunceda

I-Komatsu excavator Ngumgaqo wokusebenza kwevalvu
Ivalve ye-ls ye-Komatsu excavator ibhekisa kwivalve yolawulo lokuqukuqela kwi-hydraulic system, enokulawula ukuhamba kunye noxinzelelo lolwelo kwinkqubo yoxinzelelo lwamanzi. Kuma-excavators e-Komatsu, umgaqo wokusebenza we-valve ye-1s uquka iinkalo ezimbini, ezizezi, ukulawula ukuhamba kunye nokulawula uxinzelelo.
1. Ulawulo lokuhamba
Unyawo lokulawula ukuhamba lulawula ukuhamba kwamanzi kwinkqubo ye-hydraulic ngokulungelelanisa ukuvulwa kwe-valve ye-1s. Xa i-Komatsu excavator idinga ukulungelelanisa isantya se-hydraulic cylinder, ukuhamba kwamanzi kunokulawulwa ngokulungelelanisa ukuvulwa kwe-valve ye-1s, ukuze kufezekiswe ukulawulwa kwesantya se-cylinder hydraulic. Ivalve ye-ls ilawula indawo yokuhamba kwamanzi ngokulungelelanisa isithuba phakathi kwe-spool kunye nesihlalo, ngaloo ndlela ilawula ukuhamba kwamanzi.
2. Ukulawula uxinzelelo
Ulawulo loxinzelelo lubhekiselele ekulawuleni uxinzelelo olusebenzayo lwenkqubo ye-hydraulic ngokulungelelanisa ukusetwa koxinzelelo lwevalve ye-ls. Kwi-excavators ye-Komatsu, inkqubo ye-hydraulic kufuneka igcine uxinzelelo oluthile lokusebenza ukuqinisekisa ukuba icandelo ngalinye le-hydraulic lingasebenza ngokuqhelekileyo. Ivalve ye-ls ilawula ilahleko yoxinzelelo lolwelo oluqukuqela kumbindi wevalve ngokulungelelanisa ukuvuleka komngxuma wokudambisa, ukuze kulawulwe uxinzelelo olusebenzayo lwenkqubo.
