Isebenza kwi-excavator ye-PC60-7 yokunceda ivalve yokulawula i-hydraulic 709-20-52300

I-valve enkulu yokunceda ifakwe kwiindawo eziphezulu kunye nezisezantsi ze-valve yokulawula eyintloko, enye ephezulu kunye neyodwa ephantsi.Ivalve ibeka olona xinzelelo luphezulu kwi-hydraulic system yonke ukuba isebenze.Xa uxinzelelo lwenkqubo ludlula uxinzelelo olubekiweyo lwevalve ephambili yokunceda, ivalve enkulu yokunceda ivula isekethe yeoli yetanki yokubuya ukuze iphuphume ioyile yehydraulic ibuyele kwitanki ukukhusela yonke inkqubo yehydraulic kwaye ugweme uxinzelelo lweoyile kakhulu.

Ingaba isebenza kanjani:

① Uxinzelelo lwempompo PP luyenyuka;

② Ngaphezulu kwe-355kg / cm2 (380kg / cm2 xa i-oyile yokulinga ixinzelele ON);

③ Uxinzelelo lwempompo ukutyhala intloko ephakamisayo (2) ukoyisa intwasahlobo (1) nyanzela ukutyhala phezulu;

④ Umngxuma omncinci (kuphela φ0.5) kwi-plunger (3) iqala ukuhamba kweoli;

⑤ I-plunger (3) ityhalwa phezulu ngenxa yokwahlukana koxinzelelo phakathi kwangaphambili nangemuva (enkulu ngaphantsi, encinci ngaphezulu);

⑥ Uxinzelelo lwe-oyile emva kwetanki;

⑦ Uxinzelelo lwempompo lwehla ukuya kwi-355kg/cm2 (380kg/cm2 xa i-oyile yokulinga ivuliwe)

Xa uxinzelelo lwempompo lungaphantsi kwama-355kg/cm2:

① Intloko yokuphakamisa (2) ivaliwe phantsi koxinzelelo lwentwasahlobo (1);

Akukho kuhamba kweoli kumngxuma omncinane kwiplunger (3);

③ Umahluko woxinzelelo phakathi kweziphelo ezimbini zeplunger (3) ngu-0, kwaye ibuyela phantsi kwesenzo samandla entwasahlobo kunye noxinzelelo lweoyile;

④ Ioyile yoxinzelelo iyanqanyulwa kwindlela yetanki;

⑤ Uxinzelelo lwempompo lunokugcinwa;
