I-valve ye-Hydraulic Ivalve ye-throttle valve ene-cartridge enentambo LF12 I-valve yokulawula ukugeleza kwe-LNV-12

I-valve ye-cartridge ene-threaded iyi-valve ye-cartridge egingqiwe ejikelezayo, ekhonkwane embobeni enentambo yebhulokhi likawoyela nge-plug-in ngentambo yayo (njengoba kubonisiwe) ukuze ukwakheka kwesakhiwo sohlelo lwe-hydraulic kuminyene, umthamo wayo. incane, isisindo esilula, intambo yesikulufu ku-seal ukwenza uphawu oluqinile lungaqinisekisa ukuthi isistimu ye-hydraulic ayivuzi uwoyela.Ngakho-ke, ngenxa yokuvuza kwayo kwe-zero, ubuningi bevolumu yeyunithi ephezulu, indawo encane, kulula ukuyihlakaza nokushintsha, engabizi kakhulu, ingaxhunywa ngokuqondile ne-actuator (njenge-hydraulic cylinder, motor) ingxenye yokungenisa nokuthumela ngaphandle, ukufakwa kalula nokulungisa iphutha. kanye nezinye izinzuzo, ngokunakekelwa kwemboni ye-hydraulic yasekhaya neyangaphandle.Umfanekiso 2 ubonisa ukusetshenziswa okuvamile kwe-valve yokufaka isikulufu se-Vickers kudivayisi yokumpompa ukhonkolo ye-Sany Construction Machinery.Umgomo wayo wokusebenza uboniswa ku-FIG.1.b.Lapho i-piston isizofika ekugcineni kanye nechweba elingu-A, ngenxa yomphumela wokudambisa wembobo yokuthambisa, kwakheka umehluko wengcindezi emikhawulweni yomibili ye-cartridge valve spool, ukuze ichweba C linikeze uwoyela wokulawula wokuhlehla, bese kuthi ngokusebenzisa i-valve yokudonsa uwoyela, ukucindezela kwakhiwa ukuze kushayele umshayeli omncane we-hydraulic valve we-valve ejikayo enezinhlangothi ezine, okuholela ekuguqulweni kwe-valve yokushwibeka nokuqedela ukumpompa kukakhonkolo Isigamu somjikelezo wokushintshwa kwe-hydraulic.
 

Njengoba umshini wobunjiniyela bokupompa ukhonkolo we-SANY usebenzisa uhlelo olulodwa lwe-loop hydraulic (okungukuthi, isilinda ukhonkolo wevalvu yokusabalalisa kanye nesilinda sokumpompa ku-loop efanayo), ukhiye walolu hlelo ukuthi ungasibona kanjani isenzo esizenzakalelayo sokulandelana kwevalvu yokusabalalisa ukhonkolo. isilinda nesilinda esiyinhloko sokumpompa, ngakho-ke amasilinda amabili ayinhloko wedivayisi yokumpompa yepompo yokudonsa ye-Sany kanye neloli yepompo afakwe amavalvu e-cartridge anentambo (Umfanekiso 2.).Nikeza isignali yokulawula ingcindezi, ukuze umsebenzi wokupompa ukhonkolo ohlelweni olunembile futhi olufika ngesikhathi, okungukuthi, uhlelo lwe-hydraulic ngokwalo ukuze luqedele isilinda esiyinhloko sepompo kanye nesilinda se-valve yokusabalalisa kokunye ukushintshwa komjikelezo ogcwele wokushintshwa kwe-hydraulic, ukuqaphela kahle. indandatho yokuncela nokuncelisa.
