Ivalve ye-excavator loader engundoqo yokukhulula umpu 723-40-94501

Uninzi lwabembi baneempompo ezimbini eziphambili, ngoko ke ivalve yoncedo ephambili inezimbini (ekwabizwa ngokuba yivalve ephambili yokhuseleko), ngokulandelelana lawula impompo ephambili, kwaye impompo nganye ilawula iintshukumo ezi-3, ibhakethi kunye nengalo enkulu yokuhamba ngecala elinye. liqela, ingalo ephakathi, ukujikeleza kunye nokungaphandle kokuhamba kwecala liqela, zonke iivalvu ezimbini eziphambili zoncedo (iivalvu zoncedo olulingwayo) zilawula izenzo ezintathu ezichaseneyo.

Kwaye ekugqibeleni banazo iivalvu zabo zokunceda kwisenzo ngasinye, njengengalo ephakamisayo kunye nengalo ethobayo ezineevalvu zabo zokukhulula. I-valve engundoqo yokunceda ilawula ubukhulu becala uxinzelelo lweempompo ezimbini eziphambili, ngoko ke uxinzelelo lwezenzo ezintathu ezilawulwa yimpompo eziphambili ziyafana, ngokweemfuno, ukuba uxinzelelo lwesenzo esisodwa alwanelanga okanye luphezulu kakhulu, ngoko ke uxinzelelo lwesenzo esisodwa alwanelanga okanye lukhulu kakhulu, ngoko ke ivalve yoncedo eyahlukileyo yesenzo inokulungiswa.

Kwi-valve ephambili, kukho ukungafani okucacileyo kwezinye iivalve zokunceda. I-valve enkulu yokunceda i-excavator kunye nomsebenzi wokuqiniswa iya kuba nombhobho womqhubi omnye. Ingxaki ye-valve enkulu yokunceda ngokuqhelekileyo ukuba i-spring yangaphakathi iphukile okanye ayiphumelelanga, i-valve core igugile, kwaye wonke umsebenzi ubuthathaka kwaye uxinzelelo alukwazi ukusekwa.

Emva kokuba i-PC200-6 iqaliswe ngokupheleleyo i-hydraulic excavator, isixhobo esisebenzayo sinokuqonda iintshukumo ezahlukeneyo, kodwa impompo ephambili ithumela ingxolo engaqhelekanga.

Ngokutsho kohlalutyo lokuqala, kukholelwa ukuba ipompo ihlanjululwa okanye i-oyile yesiphaluka ixutywe nomoya. Ngoko ke, qale ulungise isixhobo esisebenzayo kwindawo yokufumanisa inqanaba leoli, kwaye ukhangele ukuba inqanaba leoli letanki ye-hydraulic ingaphantsi kwinqanaba eliphantsi le-oyile ekujoliswe kuyo, okuyiyo indawo yokunqongophala kweoli. Emva kokubuza umqhubi, ikhonkco lokutywina lombhobho we-oyile ophezulu okhokelela kwigumbi elingenazintambo le-bucket rod cylinder yatshintshwa ngenxa yokuvuza kweoli ngexesha lomsebenzi, kodwa izinga leoli alizange lihlolwe ngexesha emva kokutshintshwa. Ngoko ke, okokuqala, itanki yeoli ye-hydraulic ifakwe i-refueled kumgangatho weoli, kwaye uvavanyo lubonisa ukuba ingxolo engaqhelekanga iyancitshiswa, kodwa isekhona; Emva koko, ngokusebenzisa i-valve yokukhupha ipompo enkulu kwimpompo ephambili emva kokuvavanywa kwakhona, kufunyenwe ukuba ingxolo engaqhelekanga isekho, ebonisa ukuba ingxolo ayinakubangelwa ngokupheleleyo yimpompo yokufunxa.
