I-Excavator John Deere 200-6210 distributor hydraulic proportional solenoid valve

     Iphampu ye-hydraulic valve yokusiza ihlale iletha uwoyela, kodwa lapho ingcindezi ye-hydraulic iphezulu kakhulu, izodala umonakalo. Ngakho-ke, i-hydraulic circuit ifakwe i-valve yokuchichima ukuvimbela ukulimala kwepompo. I-hydraulic cylinder inwetshiwe ibe yinde kakhulu, noma imfushane kakhulu, noma isilinda se-hydraulic kanye ne-hydraulic motor yengeza amandla amaningi, ukuze i-hydraulic cylinder kanye ne-hydraulic motor stop, amafutha athunyelwe yipompo ye-hydraulic ngeke ahambe, ukuthi idivayisi ye-hydraulic inamandla okuqhuma, ingcindezi ye-hydraulic iphakama kakhulu, futhi ipompo ingumthwalo omkhulu kakhulu. Lokhu kuzoletha umonakalo empompini, ukuze umfutho we-hydraulic ukhuphuke ngezinga elithile, amafutha avela epompo azobuyela ku-tank yamafutha asebenzayo, kuyadingeka ukufaka indlela yokuchichima, ukuze ingcindezi ye-hydraulic ingasebenzi. khuphuka kakhulu. Ngesikhathi esifanayo, ukucindezela kokusiza kwe-valve yokusiza kungabuye kulungiswe ukuze kunqume ukuthi ingakanani i-kg / cm2 evunyelwe ukuphakama. I-valve yokusiza umsebenzi ochazwe ngenhla futhi ifakwe kumjikelezo phakathi kwepompo ye-hydraulic kanye ne-valve yokulawula, kodwa ngokuvamile ibekwe kanye ne-valve yokulawula. Uma isimo se-valve yokusiza singesihle, ukucindezela okuphansi kuzovuleka, khona-ke ukucindezela kwe-hydraulic ngeke kuqhubeke, futhi amandla e-hydraulic cylinder kanye ne-hydraulic motor kuyoba buthakathaka. Ngaphezu kwalokho, uma i-valve yokusiza ingahlobene, lapho ingcindezi iphakama, izobangela ukuvuza kwamafutha, futhi ekugcineni amafutha avela epompo kanye nokuvuza kwamafutha kuyafana, ukucindezela kwe-hydraulic akusakwazi ukuphakama, ukuze amandla e-hydraulic cylinder kanye ne-hydraulic motor ibuthakathaka
