Izincedisi zomlayishi we-excavator 375-4414 ivalve yeHydraulic

Iimpazamo eziqhelekileyo kukuba ivalve ye-solenoid ayisebenzi, ekufuneka ijongwe kule miba ilandelayo:

1. I-valve ye-solenoid edibeneyo ikhululekile okanye i-wire connector ivaliwe, i-valve ye-solenoid ayikho umbane, kwaye i-wire connector inokuqiniswa.
I-2, i-solenoid coil itshiswa ngaphandle, unako ukususa i-valve ye-solenoid wiring, ukulinganisa nge-multimeter, ukuba ivulekile, i-solenoid coil iyatshiswa. Isizathu kukuba i-coil imanzi, ibangela ukugquma okungahambi kakuhle kunye nokuvuza kwamagnetic, okubangela ukuba i-current in coil ibe nkulu kakhulu kwaye itshiswe, ngoko kuyimfuneko ukukhusela imvula ukuba ingene kwi-valve ye-solenoid. Ukongeza, intwasahlobo yomelele kakhulu, amandla okusabela makhulu kakhulu, ukujika kwekhoyili kuncinci kakhulu, kwaye ukufunxa akwanelanga kunokwenza ukuba ikhoyili itshise. Kwimeko yongxamiseko, iqhosha lemanyuwali kwikhoyili lingacinezelwa ukusuka kwindawo ethi "0" ekusebenzeni okuqhelekileyo ukuya kwindawo "1" ukwenza ivalve ivuleke.
3, ivalve ye-solenoid ibambekile: umkhono wevalve ye-solenoid kunye nespool esinococeko oluncinci (ngaphantsi kwe-0.008mm), sihlala sisodwa.
Inxalenye yokudibanisa, xa kukho ukungcola koomatshini okanye ioli yokuthambisa encinci kakhulu, kulula ukuxinga. Indlela yonyango inokuba yintsimbi yentsimbi ngomngxuma omncinci wentloko ukuze iphinde ibuye. Isisombululo esisisiseko kukususa i-valve ye-solenoid, ukukhupha umkhono we-spool kunye ne-spool, kwaye ucoce nge-CCI4, ukwenzela ukuba i-spool iguquguquke kumkhono wevalve. Xa uchitha, ingqalelo kufuneka ihlawulwe ngokulandelelana kwendibano kunye nesikhundla sangaphandle se-wiring yecandelo ngalinye, ukuze udibanise kwakhona kunye nocingo ngokuchanekileyo, kwaye ukhangele ukuba i-oil spray hole ivaliwe kwaye ingaba ioli yokuthambisa yanele.

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 egalelo levalve yomlinganiselo jikelele makhulu, ngokusisiseko kumakhulu eMa ukuya kwi-1 amp okanye ngaphezulu, kwaye amandla egalelo levalve eqhelekileyo makhulu ngokwentelekiso.
Incinci, ngokusisiseko kumashumi e-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 iimveliso zakwangoko zivuliweyo, ekufuneka ibe sisizathu sokuba zibizwe ngokuba ziivalufa ezilinganayo.
