Izesekeli zomlayishi we-375-4414 Hydraulic valve

Amaphutha ajwayelekile ukuthi i-valve ye-solenoid ayisebenzi, okufanele ibhekwe kulezi zici ezilandelayo:

1. Isixhumi se-valve ye-solenoid sikhululekile noma isixhumi socingo sivaliwe, i-valve ye-solenoid ayiwona ugesi, futhi isixhumi socingo singaqiniswa.
2, ikhoyili ye-solenoid ishisiwe, ungasusa izintambo ze-valve ye-solenoid, ukulinganisa nge-multimeter, uma ivulekile, ikhoyili ye-solenoid iyashiswa. Isizathu siwukuthi ikhoyili inomswakama, ibangela ukufakwa okungalungile kanye nokuvuza kazibuthe, okubangela ukuthi i-current in the coil ibe nkulu kakhulu futhi ishiswe, ngakho-ke kuyadingeka ukuvimbela imvula ukuthi ingangeni ku-valve ye-solenoid. Ngaphezu kwalokho, intwasahlobo inamandla kakhulu, amandla okusabela makhulu kakhulu, ukuphenduka kwekhoyili mancane kakhulu, futhi ukumunca akwanele kungenza ikhoyili ishise. Esimeni esiphuthumayo, inkinobho yamanuwali kukhoyili ingacindezelwa isuke endaweni ethi "0" ekusebenzeni okujwayelekile iye endaweni ethi "1" ukwenza ivalvu ivuleke.
3, i-valve ye-solenoid ibambekile: umkhono wevalve ye-solenoid kanye ne-spool enemvume encane (ngaphansi kuka-0.008mm), ngokuvamile ayiwodwa.
Ukuhlanganiswa kwengxenye, lapho kunokungcola kwemishini noma amafutha okugcoba amancane, kulula ukubhajwa. Indlela yokwelapha kungaba ucingo lwensimbi ngembobo encane yekhanda ukuze ibuyele emuva. Isixazululo esiyisisekelo ukukhipha i-valve ye-solenoid, ukukhipha umkhono we-spool kanye ne-spool, bese uhlanza nge-CCI4, ukuze i-spool ikwazi ukuguquguquka kumkhono we-valve. Lapho uhlakazwa, kufanele kuqashelwe ukulandelana komhlangano kanye nesimo se-wiring sangaphandle sengxenye ngayinye, ukuze kuhlanganiswe kabusha futhi kufakwe ucingo ngendlela efanele, futhi uhlole ukuthi umgodi wokufafaza uwoyela uvinjelwe yini nokuthi amafutha okugcoba anele yini.

Ukushayela kuhlukile. Idivayisi yokushayela ye-valve ye-proportional iwuzibuthe we-proportional, futhi idivayisi yokushayela ye-servo valve iyinjini yamandla noma i-torque motor, futhi imingcele yokusebenza ihlukile. I-Hysteresis, indawo efile emaphakathi, umkhawulokudonsa, ukunemba kokuhlunga nezinye izici zihlukile, ngakho-ke izikhathi zokufaka isicelo zihlukile, ama-servo valves nama-servo proportional valves asetshenziswa kakhulu ezinhlelweni zokulawula iluphu evaliwe, ama-valve alinganayo kwezinye izakhiwo asetshenziswa ikakhulukazi ku-loop evulekile. amasistimu okulawula kanye nezinhlelo zokulawula isivinini esivaliwe.
Amandla okufaka wevalvu evamile yokulingana makhulu, ngokuyisisekelo kumakhulu ka-Ma ukuya ku-1 amp noma ngaphezulu, futhi amandla okufaka wevalvu evamile makhulu uma kuqhathaniswa.
Encane, ngokuyisisekelo emashumini e-MA; Ukunemba kokulawula kwe-valve yokulinganisa kuncane kancane, i-hysteresis inkulu kune-valve ye-servo, futhi ukunemba kokulawula kwe-valve evamile kuphezulu, kodwa izidingo zamafutha nazo ziphakeme.
Kuyaqondwa kusukela esakhiweni ukuthi i-spool ye-valve yokulinganisa ilinganiswe ngamandla kagesi kanye nomfutho we-hydraulic kanye namandla asentwasahlobo, kuyilapho i-valve evamile ilinganiswa nokucindezela kwe-hydraulic, ngakho-ke i-valve yokulingana ayinayo inzuzo ekulawuleni ukugeleza okukhulu nokucindezela okukhulu. Kukhona ama-valve alinganayo imikhiqizo yokuqala evuliwe, okufanele kube isizathu esenza ukuthi abizwe ngokuthi ama-proportional valves.
