Excavator Chalk hydraulic solenoid valve original TM68501 proportional solenoid valve

Vavu ya solenoid pa pampu ya hydraulic nthawi zambiri imakhala ndi ziwiri, imodzi ndi valavu ya TVC solenoid, ina ndi LS-EPC solenoid valavu, yoyambayo imakhala ndi udindo wozindikira chizindikiro kuchokera ku sensa ya injini, kusintha mphamvu ya injini ndi pampu ya hydraulic. machesi mphamvu, ngati kuonongeka, mwina injini ndi yodzaza ndi galimoto, osakwanira mphamvu, kapena injini ndi kovuta kuyamba.
Wotsirizirayo ali ndi udindo wowona ntchito ya dalaivala ndi kusintha kwa kukula kwa katundu wakunja, ngati kuonongeka, kumayambitsa kufooka pakukumba, kugwira ntchito pang'onopang'ono kwa makina onse, luso losauka laling'ono, komanso palibe zida zothamanga kwambiri. Tiyenera kukumbukira kuti pali valavu imodzi ya TVC solenoid isanayambe ndi pambuyo pa mpope, ndi valavu imodzi yokha ya LS-EPC.
Ma hydraulic pump drive shaft sangathe kupirira mphamvu ya radial ndi axial mphamvu, kotero sikuloledwa kukhazikitsa mawilo a lamba, magiya, ma sprockets mwachindunji kumapeto kwa shaft, nthawi zambiri ndi cholumikizira kulumikiza shaft yoyendetsa ndi shaft pampu.
Ngati chifukwa cha zifukwa zopangira, mlingo wa coaxial wa mpope ndi kugwirizana umaposa muyezo, ndipo pali kupatuka pa msonkhano, mphamvu ya centrifugal imawonjezera kusinthika kwa kugwirizana ndi kuwonjezeka kwa liwiro la mpope, ndipo mphamvu ya centrifugal ikuwonjezeka. Zotsatira za kuzungulira koyipa, zotsatira za kugwedezeka ndi phokoso, motero zimakhudza moyo wautumiki wa mpope. Kuphatikiza apo, palinso zinthu zina zomwe zimathandizira monga kumasula pini yolumikizira osati kulimbitsa nthawi yake.

Excavator electromagnetic relief valve vuto ndi njira yothetsera mavuto:

1. Kusintha kwamphamvu kwadongosolo

Zomwe zimayambitsa kusinthasintha kwamphamvu ndi:
① Zomangira zomwe zimasinthira kupanikizika zimapangitsa kuti mtedza wotsekera usungunuke chifukwa cha kugwedezeka, zomwe zimapangitsa kusinthasintha kwamphamvu;
② Mafuta a Hydraulic sali oyera, pali fumbi laling'ono, kotero kuti spool yayikulu yotsetsereka isasinthe. Izi zimabweretsa kusintha kwamphamvu kwanthawi zonse. Nthawi zina valavu imatha kupanikizana;
③ Chophimba chachikulu cha valve sichiri chosalala, chomwe chimachititsa kuti dzenje lonyowa litsekedwe likadutsa;
(4) Pamwamba pazitsulo zazikuluzikulu za valve sichigwirizana bwino ndi cone ya mpando wa valve, ndipo sichikupukutidwa bwino;
⑤ Bowo lonyowa lapakati pa valve ndi lalikulu kwambiri ndipo silimagwira ntchito yonyowa;
Vavu yoyendetsa yoyendetsa masika amapindika, zomwe zimapangitsa kuti pasakhale kulumikizana pakati pa spool ndi mpando wa cone, kuvala kosagwirizana.
Yankho:
① Tsukani tanki yamafuta ndi mapaipi pafupipafupi, ndikusefa mafuta oyambira omwe amalowa mu thanki yamafuta ndi mapaipi;
(2) Ngati pali fyuluta mu payipi, gawo lachiwiri la fyuluta liyenera kuwonjezeredwa, kapena kulondola kwa kusefera kwa gawo lachiwiri kuyenera kusinthidwa; Sungunulani ndi kuyeretsa zigawo za valve ndikusintha mafuta oyera a hydraulic;
③ Konzani kapena kusintha magawo osayenerera;
④ Chepetsani kabowo konyowa moyenera.

g, kuvala mphete za mphira osati kusinthidwa panthawi yake.
