I-PC200-6 PC300-6 ivalve engundoqo yokunceda umpu 708-2L-04312

Ivalve yokukhulula i-hydraulic excavators inemisebenzi emine engundoqo:

I-1, kwimpompo yobungakanani (ipompo yegiya) inkqubo ye-hydraulic, esetyenziselwa ukugqithisa ukuhamba kweoli engaphezulu kwitanki ukugcina i-hydraulic system pressure constant (malunga rhoqo).

I-2, kwinkqubo yepompo eguquguqukayo ye-hydraulic system, kuphela xa uxinzelelo ludlula ixabiso loxinzelelo olusethiweyo, ukugqithisa kuvulwa, ukwenzela ukuba uxinzelelo lwenkqubo alusayi kuphakanyiswa, kwaye indima yokukhusela ukhuseleko ihlala ibizwa ngokuba yi-valve yokunceda.

I-3, kwinkqubo, esetyenziselwa ukukhusela i-actuator (njenge-cylinder) okanye iinxalenye zesakhiwo phantsi kwesenzo samandla angaphandle anamandla angonakaliswa, kulo mzekelo, i-valve yokunceda, siyibiza ngokuba yi-valve overload.

4, njengevalve yokunciphisa uxinzelelo, indlela ejikelezayo yokunciphisa, ukunciphisa uxinzelelo.

Umgaqo osebenzayo wevalve yokunceda

1. Uxinzelelo lwempompo PP luyenyuka

2, ngaphezu kwe-21.6MP

3, uxinzelelo lwempompo ukutyhala intloko ephakamisayo ukoyisa amandla entwasahlobo ukutyhala phezulu

4. Umngxuma omncinci kwiplunger (kuphela i-0.5) iqala ukuhamba kweoli

5. Iplunger ityhalelwa phezulu ngenxa yomahluko woxinzelelo phakathi komphambili nomva (umzantsi mkhulu kwaye umphezulu umncinci)

I-6, i-oyile yoxinzelelo ibuyele kwitanki

I-7, uxinzelelo lwempompo luyehla kude kube yi-21.6
