Ivalve ye-hydraulic balance valve Excavator hydraulic cylinder valve core NFCD-LFN

Ivalve yokukhulula iindlela eziqhelekileyo zokusombulula ingxaki

I-1) I-port yokukhupha i-valve yokunceda i-pilot ivaliwe kwaye ayivalwanga, kwaye ioli yokulawula ayinalo uxinzelelo, ngoko ke inkqubo ayinalo uxinzelelo, kwaye i-port yokukhupha kufuneka ivalwe ngokungqongqo;

I-2) Isiphaluka se-oyile esilawuli kude esidityaniswe yi-remote control port ye-valve yokunceda ivuliwe ukulawula ukubuyela kweoli kwi-tank, ngoko akukho xinzelelo kwinkqubo. I-remote control oil circuit kufuneka ihlolwe kwaye i-oil circuit ye-oil control return to the tank kufuneka ivalwe;

I-3) Umngxuma omdaka we-valve yokunceda i-pilot ivaliwe, okubangela ukuba akukho xinzelelo kwinkqubo. Umngxuma wokudambisa kufuneka ucocwe kwaye kufakwe ioli endaweni yayo;

4) Ivalve yekhowuni elahlekileyo okanye ibhola yentsimbi okanye intwasahlobo elawula uxinzelelo kufuneka itshintshwe ngexesha;

5) Ivalve yokuvuza ibambeke kwindawo evuleke ngokupheleleyo ngobumdaka, kwaye kufuneka icocwe ngexesha;

6) Impompo ye-hydraulic akukho xinzelelo, kufuneka ijongane nokungaphumeleli kwepompo ye-hydraulic;

7) Amacandelo enkqubo okanye umonakalo wepayipi kunye nenani elikhulu lokuvuza kweoli, kufuneka lihlolwe ngexesha lokulungisa okanye ukubuyisela.

I-3, uxinzelelo lwenkqubo lukhulu kakhulu, uhlengahlengiso alusebenzi, kufuneka luthathe amanyathelo ahambelana nezi zizathu zilandelayo:

1) Isiphaluka sokulawula i-oyile ukusuka kwi-valve enkulu ukuya kwi-valve yomqhubi ivaliwe, i-valve yomqhubi we-pilot ayilawuli uxinzelelo lweoli, khangela i-oil circuit ukuze idibanise;

2) I-oil drain port yangaphakathi ye-valve yokulinga ivalwe ngokungcola, kwaye i-valve yomqhubi ayikwazi ukulawula uxinzelelo. I-port yokukhutshwa kweoli yangaphakathi yevalve yokulinga kufuneka icocwe;

3) Ukunxiba komngxuma wokuthomalalisa kukhulu kakhulu, ibhalansi yoxinzelelo lweoyile kuzo zombini iziphelo zespool ephambili, ivalve yesilayidi ayinakuvulwa, kufuneka icinezelwe kwiphepha lentsimbi elingenasici njengomgodi wokudambisa okanye ucingo oluthambileyo olufakiweyo. emngxunyeni, vala inxalenye yomngxuma wokufuma;

4) Ukungcola kweoli, i-valve yesilayidi inamathele kwindawo evaliweyo.
