YeKomatsu PC200-8 ivelufa yokukhulula umpu ongundoqo

Into esithetha ngayo kwivalvu engundoqo yokunceda kuxa uxinzelelo lwenkqubo lunyuka kancinci, imodeli yesithandathu
Xa umehluko woxinzelelo phakathi kweziphelo ezimbini zevalve ephambili ye-plunger idlula umsebenzi we-spring ethambileyo yevalve ephambili, ivalve ephambili ye-plunger iphakanyisiwe, ivalve ephambili ivuliwe, intwasahlobo iqhagamshelwe kwitanki yeoli, isixa esikhulu. I-oyile ihlanjululwa kwizibuko levalvu engundoqo, ize iphinde iqukuqelele emva kwitanki yeoli ngezibuko le-oyile yokubuya, eyinkqubo yokulawula ukuphuphuma koxinzelelo. Ukuqonda lo mgaqo unokuqonda umgaqo osebenzayo we-boom ukugcina i-valve phantsi ngokufanisa.
Xa ingalo ye-hydraulic excavator yehlisiwe, kubalulekile ukuba uqaphele ukuba ixhomekeke kwivalve ye-PPC elawulwa ukusuka kwi-toggle.
I-oyile yoxinzelelo olukhokelayo iqala ityhala ivalve yesilayidi elawula ivalve engundoqo (ivalve ilingana nevalve yokulinga kwivalve yokuhlangula, ehamba ngeli xesha.
Ioyile ekwigumbi elisezantsi lengalo ibuyela kwitanki ngomngxuma ongaphakathi we-oyile wevalve engundoqo idlula kwindlela evulwe yivalve yesilayidi. Xa ukuhamba kweoli yoxinzelelo kudlula kumngxuma wokudambisa wevalve ephambili yevalve yokubamba, ukuhla koxinzelelo kuveliswa, ukwenzela ukuba uxinzelelo lweoyile olusebenza kwiziphelo eziphezulu nasezantsi zevalve ephambili ayilingani, yenze umahluko othile woxinzelelo. Ivalve engundoqo iyavulwa, kwaye i-oyile yoxinzelelo equkuqela ukusuka ezantsi kwe-boom ihamba ngevalve ephambili ukuya kwivalve yokulawula i-boom. Xa kukho uxinzelelo oluphezulu olungaqhelekanga kwisiphaluka esisezantsi se-boom cylinder, i-valve yokukhusela kwi-valve yokubamba ivuliwe ukuze idlale indima yokukhusela.
