Ivalve yeHydraulic valve Ivalve ephothiweyo yekhatriji LF12 Ivalve yokulawula ukuhamba kweLNV-12

Ivalve yecartridge ephothiweyo yivalve yecartridge ejikelezayo, ethi ijijelwe kumngxunya weblokhi yeoyile ngeplagi-ngaphakathi ngomsonto wayo (njengoko kubonisiwe) ukuze ukubunjwa kwenkqubo ye-hydraulic kuxinene ngakumbi, umthamo wayo. incinci, ubunzima obukhaphukhaphu, intambo yesijija kwitywina ukwenza itywina eliqinileyo linokuqinisekisa ukuba inkqubo yolwelo olumanzi ayivuzi ioyile. Ke ngoko, ngenxa yokuvuza kwayo, iyunithi ephezulu yoxinaniso lweyunithi, indawo encinci, kulula ukuyichitha kunye nokutshintsha, ingabizi kakhulu, inokuqhagamshelwa ngokuthe ngqo kwi-actuator (efana ne-hydraulic cylinder, motor) yokungenisa kunye nokuthumela ngaphandle inxalenye, ukufakwa lula kunye nokulungiswa kweempazamo. kunye nezinye iingenelo, ngoqwalaselo lwasekhaya kunye nolwangaphandle loshishino lwehydraulic. Umzobo we-2 ubonisa ukusetyenziswa okuqhelekileyo kwe-valve yokufaka i-Vickers screw kwisixhobo sokumpompa sekhonkrithi seSany Construction Machinery. Umgaqo wayo wokusebenza uboniswe kwi-FIG. 1.b. Xa i-piston imalunga nokufikelela kwinqanaba lesiphelo kunye ne-cross port A, ngenxa yempembelelo yokudambisa yomngxunya, umahluko woxinzelelo lwenziwa kuzo zombini iziphelo ze-cartridge valve spool, ukuze izibuko C ibonelele ioli yokubuyisela umva, kwaye emva koko. ngokumanzisa kwevalve yokutsalwa kwe-oyile, uxinzelelo lwakhiwe ukuqhuba ivalve encinci ye-hydraulic yevalve eneendlela ezine, okukhokelela ekuguqulweni kwevalve yokujingi kunye nokugqibezela ukumpompa ikhonkrithi Isiqingatha somjikelo woguqulo lwehydraulic.
 

Kuba oomatshini bobunjineli be-SANY bekhonkrithi bokumpompa bamkela inkqubo enye ye-loop hydraulic (oko kukuthi, isilinda sevalve yokusasaza ikhonkrithi kunye necylinder yokumpompa zikwilophu enye), isitshixo sale nkqubo yindlela yokuqonda isenzo esizenzekelayo sokulandelelana kwevalve yosasazo lwekhonkrithi. isilinda kunye ne-cylinder master yokumpompa, ngoko ke iisilinda ezimbini eziphambili zesixhobo sokumpompa se-Sany drag pump kunye nelori yepompo zixhotyiswe ngeevalvu zekhatriji ezinemisonto (Umfanekiso 2.). Ukubonelela ngomqondiso wokulawula uxinzelelo, ukwenzela ukuba umsebenzi wokumpompa ikhonkrithi kwinkqubo echanekileyo kunye nexesha elifanelekileyo, oko kukuthi, inkqubo ye-hydraulic ngokwayo ukugqiba i-cylinder master yepompo kunye ne-cylinder yevalve yokusabalalisa yokutshintshwa kokutshintshwa komjikelo ogcweleyo we-hydraulic commutation, uqonde kakuhle. Iringi yokufunxa kunye nokutyisa.
