I-excavator uJohn Deere 200-6210 umsasazi we-hydraulic proportional solenoid valve

     Ipompo ye-valve yokunceda i-hydraulic pump ihlala ihambisa ioli, kodwa xa uxinzelelo lwe-hydraulic luphezulu kakhulu, luya kubangela umonakalo.Ngoko ke, isiphaluka se-hydraulic sixhotyiswe nge-valve yokuphuphuma ukukhusela umonakalo kwimpompo.I-cylinder ye-hydraulic yandisiwe kakhulu, okanye imfutshane kakhulu, okanye i-hydraulic cylinder kunye ne-hydraulic motor yongeza amandla amaninzi, ukwenzela ukuba i-cylinder ye-hydraulic kunye ne-hydraulic motor stop, i-oyile ethunyelwe yipompo ye-hydraulic ayiyi kuhamba, ngoko ke. ukuba isixhobo se-hydraulic sinakho ukuqhuma, uxinzelelo lwe-hydraulic luphakama kakhulu, kwaye ipompo inzima kakhulu.Oku kuya kuzisa umonakalo kwimpompo, ukwenzela ukuba uxinzelelo lwe-hydraulic luphakame kwinqanaba elithile, ioli evela kumpompo iya kubuyela kwitanki yeoli esebenzayo, kuyimfuneko ukufakela indlela yokuphuphuma, ukwenzela ukuba uxinzelelo lwe-hydraulic lungabikho. ukuphakama kakhulu.Ngelo xesha, uxinzelelo lwe-valve yokunceda lunokulungiswa kwakhona ukuze kuqinisekiswe ukuba ingakanani i-kg / cm2 evunyelwe ukunyuka.I-valve yokunceda ngumsebenzi ochazwe ngasentla kwaye ufakwe kwisiphaluka phakathi kwepompo ye-hydraulic kunye ne-valve yokulawula, kodwa ngokuqhelekileyo ibekwe kunye ne-valve yokulawula.Ukuba imeko ye-valve yokunceda ayilungile, uxinzelelo oluphantsi luya kuvula, ngoko uxinzelelo lwe-hydraulic aluyi kuqhubeka, kwaye amandla e-hydraulic cylinder kunye ne-hydraulic motor iya kuba buthathaka.Ukongeza, ukuba i-valve yokunceda ayihambelani, xa uxinzelelo luphakama, luya kubangela ukuvuza kweoli, kwaye ekugqibeleni ioli evela kumpompo kunye nokuvuza kweoli iyafana, uxinzelelo lwe-hydraulic alunakuphinda luphakame, ukuze amandla ecylinder yehydraulic kunye ne-hydraulic motor ibuthathaka
