Oyenera CAT Carter 2522237 excavator Chalk solenoid vavu 252-2237 24V

Proportional solenoid valve

Momwe zimagwirira ntchito:

Zigawo zonse za valavu ya solenoid ndi koyilo yamagetsi malinga ndi gawo lamagetsi, ndiye kuti, chowongolera. Inductor ikapatsidwa chizindikiro chamagetsi, gawo lamagetsi lomwe limapangidwa ndi pano limapangitsa kuti valavu yapakati isunthike ndikuzindikira kusintha kwa magawo olamulidwa.
Chizindikiritso chaubwino:
Koyilo iliyonse yamagetsi imakhala ndi mtengo wokhazikika wokana R, koma R uyu sangakhale "0" kapena "∞", pomwe R= "0" ikuwonetsa dera lalifupi lamkati: pomwe R= "∞" ikuwonetsa dera lotseguka lamkati; ndi
Kukana kwa koyilo ku nyumba sikungakhale "0". Ngati zomwe zili pamwambazi zitha kukumana ndipo valavu ya solenoid sikugwira ntchito, zikhoza kukhala kuti kulowetsa kwa chizindikiro ndikolakwika kapena chigawo cha valve chatsekedwa.

Pressure sensor

Momwe zimagwirira ntchito:

Kwa sensa yama waya atatu, imatha kumveka ngati potentiometer ya waya atatu kapena resistor variable, nthawi zambiri imawonjezera voteji ya 5V ku mizere iwiri (1 mzere ndi mizere 3), ndipo mtengo woyezera ukasintha, mphamvu yamagetsi mzere wapakati (mizere iwiri) umasintha pakati pa 0 ndi 5V.

Chizindikiritso chaubwino:
1. Tulutsani mzere wapakati, sinthani chizindikiro choyezera, gwiritsani ntchito multimeter kuti muyese ngati magetsi a mzere wapakati (2 mizere) amasintha ndi chizindikiro choyezera.
2. Wolokani sensa popanda vuto

Mfundo yogwirira ntchito ya proportional electromagnetic control valve imayambitsidwa

Zimatengera mfundo ya solenoid on-off valve: mphamvu ikatha, kasupe amakankhira pachimake pampando, kuchititsa kuti valavu itseke. Koyiloyo ikapatsidwa mphamvu, mphamvu yamagetsi yopangidwa ndi electromagnetic imapambana mphamvu yamasika ndikukweza pachimake, motero kutsegulira valavu. Valavu yofananira ya solenoid imapanga zosintha zina pamapangidwe a valavu ya solenoid: imapanga malire pakati pa mphamvu yamasika ndi mphamvu yamagetsi yamagetsi pansi pa koyilo iliyonse. Kukula kwa koyilo yapano kapena kukula kwa mphamvu yamagetsi kumakhudza kugunda kwa plunger ndi kutseguka kwa ma valve, ndipo kutsegula kwa valve (kuyenda) ndi koyilo (chizindikiro chowongolera) ndiubwenzi wabwino kwambiri. Direct acting proportional solenoid valve imayenda pansi pa mpando. Sing'anga imayenda kuchokera pansi pa mpando, ndipo mayendedwe a mphamvu ndi ofanana ndi mphamvu yamagetsi, ndipo mosiyana ndi mphamvu ya masika. Choncho, m'pofunika kukhazikitsa ziwerengero zazikulu ndi zazing'ono zomwe zimagwirizana ndi zomwe zimagwira ntchito (coil current) pakugwira ntchito. Valavu yofananira ya solenoid ya Drey fluid imatsekedwa (NC, yomwe nthawi zambiri imatsekedwa) mphamvu ikazimitsidwa.
