umlayishi Umgangatho oPhezulu wevalve ye-solenoid elinganayo 25/222913

     Iimpazamo eziqhelekileyo zevalve ye-solenoid 

Ukuvuza komoya kuya kubangela uxinzelelo lomoya olwaneleyo, okwenza kube nzima ukuvula nokuvala ivalve enyanzelekileyo, kuba i-gasket yokutywina yonakele okanye i-valve ye-spool igugile kwaye imigodi emininzi ibanjwe. Xa ujongene nokungaphumeleli kwe-valve ye-solenoid yenkqubo yokutshintsha, ixesha elifanelekileyo kufuneka likhethwe ukujongana ne-valve ye-solenoid xa iphuma amandla. Ukuba ukuqhutyelwa phambili akukwazi ukugqitywa ngaphakathi kwesithuba sokutshintsha, inkqubo yokutshintsha inokunqunyanyiswa kwaye iphathwe ngokuzolileyo.

Ukuqhuba kwahlukile. Isixhobo sokuqhuba sevalve elinganiselayo yi-electromagnetic elinganayo, kwaye isixhobo sokuqhuba sevalve ye-servo yimoto yamandla okanye i-torque motor, kwaye iiparamitha zokusebenza zahlukile. I-Hysteresis, indawo efileyo ephakathi, i-bandwidth, ukuchaneka kokucoca kunye nezinye iimpawu zahlukile, ngoko ke amaxesha osetyenziso ahlukile, iivalvu ze-servo kunye ne-servo proportional valves zisetyenziswa ikakhulu kwiinkqubo zokulawula i-loop-loop, iivalvu ezilinganayo zezinye izakhiwo zisetyenziswa ikakhulu kwi-loop evulekileyo. iinkqubo zokulawula kunye neenkqubo zokulawula isantya esivaliweyo.

Amandla okufaka i-valve yokulinganisa ngokubanzi makhulu, ngokusisiseko kumakhulu e-Ma ukuya kwi-1 amp okanye ngaphezulu, ngelixa amandla okufaka i-valve eqhelekileyo incinci, ngokusisiseko kwishumi le-MA; Ukuchaneka kokulawulwa kwe-valve yokulinganisa kuncinci, i-hysteresis inkulu kune-valve ye-servo, kwaye ukuchaneka kokulawula kwe-valve eqhelekileyo kuphezulu, kodwa iimfuno zeoli nazo ziphezulu.

Kuqondwa kwisakhiwo ukuba i-spool ye-valve yokulinganisa ilungelelaniswa ngamandla ombane kunye noxinzelelo lwe-hydraulic kunye ne-spring force, ngelixa i-valve eqhelekileyo ilungelelaniswa noxinzelelo lwe-hydraulic, ngoko i-valve yokulinganisa ayinayo inzuzo ekulawuleni ukuhamba okukhulu kunye noxinzelelo oluphezulu. Kukho iivalvu ezilinganayo Z iimveliso zakwangoko zivuliwe, ekufuneka ibe sisizathu sokuba ibizwa ngokuba ziivalvu ezilinganayo.

Kwisicelo, i-valve eqhelekileyo isetyenziswa ngokubanzi, ayisetyenziselwa kuphela indawo echanekileyo, isantya kunye nolunye ulawulo, kodwa kunye nesenzo, ngoko ke amandla okuqhuba imoto oyiqhubayo yinkqubo ye-servo, enzima ukufezekisa ngokulinganayo. iivalve.
