Isebenza kwi-ExCavatator PC60-7-7 I-Colve ye-Halve Haldraulic Palve 709-20-5200

I-valve ephambili yoncedo ifakwe kwimiphetho ephezulu nangaphantsi kwevalve ephambili, enye ephezulu kunye neyezantsi. I-valve ibeka elona xinzelelo luphezulu kuyo yonke inkqubo ye-hydraulic yokusebenza. Xa uxinzelelo lwenkqubo lugqitha uxinzelelo lwevalve ephambili yokunceda, ivalve ephambili yoncedo ivula itanki yokubuya yetanki yokukhusela i-hyddraulic of i-thydraulic ibuyele kuyo yonke inkqubo ye-hydraulic kwaye iphephe uxinzelelo lweoyile

Ingaba isebenza kanjani:

① uxinzelelo lwempompo lwe-PP luyavuka;

② Ngaphezulu kwe-355kg / CM2 (i-380kg / cm2 xa uxinzelelo lweoyile ye-Pilot kwi);

③ uxinzelelo lwe-pump yokutyhala intloko yokuphakamisa (2) ukoyisa intwasahlobo (1) amandla okutyhala phezulu;

④ Umngxunya omncinci (kuphela φ0.5) kwi-plungur (3) iqala ukuhamba ioyile;

⑤ I-plisinger (3) ityhala phezulu ngenxa yomahluko phakathi komphambili kwaye ngasemva (omkhulu ngezantsi);

⑥ Ingcinezelo I-O I-OSULY KWI-TAKIRN

⑦ Uxinzelelo lwe-pump deffied ukuya kwi-355kg / CM2 (i-380kg / cm2 xa uxinzelelo lwe-Pilot oli on)

Xa uxinzelelo lwempompo lungaphantsi kwe-355kg / cm2:

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

Akukho moto yokuhamba ioyile kumngxunya omncinci kwi-plumzana (3);

③ Umahluko woxinzelelo phakathi kweziphelo ezimbini ze-plum (3) ngu-0, kwaye ibuya phantsi kwesenzo somkhosi wasentwasahlobo kunye noxinzelelo lweoyile;

Ioyile yoxinzelelo ikhutshiwe kwindlela yetanki;

⑤ uxinzelelo lwempompo lungagcinwa;
