Vavu yofufutira ya SK200-5 yofanana ndi solenoid valve YN22V00029F1

Valavu ya excavator solenoid imapangidwa ndi koyilo yamagetsi ndi maginito pachimake, kuphatikiza mabowo amodzi kapena angapo a valavu, kugwiritsa ntchito mfundo yamagetsi yama electromagnet kuti muwongolere kayendedwe ka valavu, malinga ndi malangizo a actuator kugawa koyenera kwa hydraulic mafuta. kwaniritsani zofananira, kuwongolera ndikusintha ma hydraulic mafuta oyenda, mayendedwe, liwiro ndi magawo ena mu hydraulic system.

Nambala ikhoza kutsimikizira kusinthasintha ndi kulondola kwa ulamuliro.

1. Mfundo yogwirira ntchito ya excavator solenoid valve
Wofukula makamaka amagwiritsa ntchito valavu ya solenoid yolunjika, yomwe ili ndi ubwino wowongolera bwino, kuchitapo kanthu mofulumira, kosavuta kukwaniritsa kulamulira kwakutali, ndipo imatha kugwira ntchito nthawi zonse pansi pa vacuum, kupanikizika koipa ndi zero.
The excavator solenoid valve ali ndi chipinda chotsekedwa mkati, thupi la valve liri pakati pa chipindacho, ndipo malekezero awiri a thupi la valve amapangidwa ndi ma electromagnets malinga ndi zosowa, kapena mapeto amodzi okha amapangidwa ndi ma electromagnets. Pogwiritsa ntchito mphamvu ya maginito yopangidwa ndi mfundo ya inductance, spool yolamulira imasuntha kuti ikwaniritse kusintha kwa dera la mafuta, pamene coil ya electromagnet ikapatsidwa mphamvu, maginito amakokera mbali ina, ndikukankhira spool kuti asunthire mbali ya kuyamwa, potero kutsekereza kapena kuvumbula mabowo osiyanasiyana amafuta, ndipo mafutawo adzalowa mapaipi osiyanasiyana molingana ndi malangizo. Ngati coil ya solenoid ya solenoid valve itenthedwa kapena kudulidwa, sichitha kupanga mphamvu ya maginito, ndipo chigawo cha valve sichingasunthidwe, ndipo wofukula sangagwire ntchito zina.
