LS valve relief valve 708-1W-04821 Komatsu excavator zowonjezera valavu hydraulic pump

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.

Valavu ya solenoid imagwiritsa ntchito maginito amagetsi kukankhira pachimake valavu kuti iwongolere komwe mpweya woponderezedwa umalowera, potero kuwongolera kolowera kwa pneumatic actuator switch.
Ma electromagnet omwe amagwiritsidwa ntchito poyendetsa valavu ya solenoid amagawidwa kukhala AC ndi DC:

1. Mphamvu yamagetsi yamagetsi yamagetsi ya AC nthawi zambiri imakhala 220 volts. Amadziwika ndi mphamvu yayikulu yoyambira, nthawi yochepa yosinthira komanso mtengo wotsika. Komabe, valavu ikamatidwa kapena kuyamwa sikukwanira ndipo chitsulo sichimayamwa, maginito amagetsi ndi osavuta kuwotcha chifukwa chakuchulukirachulukira, kotero kudalirika kogwira ntchito kumakhala kocheperako, kukhudzidwa kwa zochita, komanso moyo. ndi otsika.

Mphamvu yamagetsi yamagetsi ya 2.DC nthawi zambiri imakhala 24 volts. Ubwino wake ndi ntchito yodalirika, osati chifukwa spore yakhazikika ndikuwotchedwa, moyo wautali, kukula kochepa, koma mphamvu yoyambira ndi yaying'ono kuposa maginito amagetsi a AC, ndipo pakalibe magetsi a DC, kufunikira kwa zida zowongolera.
Kuti apititse patsogolo kudalirika kwa ntchito ndi moyo wa valavu yosinthira ma elekitiroma, m'zaka zaposachedwa, maginito onyowa akugwiritsidwa ntchito kwambiri kunyumba ndi kunja, maginito amagetsi awa ndi ndodo ya slide valve kukankhira sikuyenera kusindikizidwa, kuthetsa mikangano. mphete yosindikizira yooneka ngati O, koyilo yake yamagetsi yamagetsi kunja yosindikizidwa mwachindunji ndi pulasitiki yaumisiri, osati chipolopolo china chachitsulo, chomwe chimatsimikizira kutsekeka, komanso kumathandizira kutulutsa kutentha, ntchito yodalirika, Kutsika kochepa, moyo wautali.
Pakalipano, valavu ya solenoid kunyumba ndi kunja imagawidwa m'magulu atatu (omwe ndi: mtundu wachindunji, mtundu woyendetsa ndege), ndi kusiyana kwa mavavu a chimbale ndi zinthu ndi kusiyana kwa mfundo kumagawidwa m'magulu asanu ndi limodzi. (mawonekedwe a diaphragm molunjika, mawonekedwe a masitepe apawiri, mawonekedwe a filimu yoyendetsa, mawonekedwe a pistoni, mawonekedwe a piston, mawonekedwe a piston).

Ma electromagnetic valve of excavator amagwira ntchito yolamulira.
 

1, valavu ya solenoid ndi zida zamafakitale zomwe zimayendetsedwa ndi ma electromagnetic, zomwe zimagwiritsidwa ntchito kuwongolera zida zoyambira zamadzimadzi, ndi za actuator, osati ma hydraulic, pneumatic. Amagwiritsidwa ntchito m'makina owongolera mafakitale kuti asinthe njira ya media, kuyenda, kuthamanga ndi magawo ena.

2, valavu ya solenoid ikhoza kuphatikizidwa ndi maulendo osiyanasiyana kuti akwaniritse zomwe akufuna, ndipo kulondola ndi kusinthasintha kwa kayendetsedwe kake kakhoza kutsimikiziridwa. Pali mitundu yambiri ya ma valve a solenoid, ma valve osiyana a solenoid amagwira ntchito m'malo osiyanasiyana a kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, ndi zina zotero.
