Vavu yofukula solenoid TM70402 24V hydraulic pump proportional solenoid valve

 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.

Kupanikizika kwadongosolo sikungapite konse

Chifukwa 1:
① Bowo lalikulu la spool latsekedwa, monga kusonkhana kwa spool yaikulu sikutsukidwa, mafuta ndi onyansa kwambiri kapena msonkhano ndi zinyalala;
② Kusokonekera kwabwino, kusakwanira bwino kwa msonkhano pakusonkhana, kusintha kosasinthika kwa kusiyana pakati pa mavavu, spool yayikulu imakhazikika poyera, kusanja bwino;
③ Chitsulo chachikulu chokhazikitsanso spool chimasweka kapena kupindika, kuti spool yayikulu isakhazikitsidwenso.
Yankho:
① Sulani dzenje lalikulu lotsuka mavavu ndikumanganso;
② Sefa kapena kusintha mafuta;
③ Limbani kapu yomangira valavu kuti mulowe m'malo mwa kasupe wosweka.

Chifukwa 2: Vavu yoyendetsa ndi yolakwika
① Kasupe wosintha wathyoka kapena osakwezedwa,
② Valovu kapena mpira wachitsulo sunakhazikitsidwe,
③ Valovu ya taper yathyoka. Yankho: Bwezerani zigawo zowonongeka kapena kusintha magawo kuti mubwezeretse valavu yoyendetsa ndege kuti igwire ntchito yabwino.

Chifukwa 3: valavu yakutali ya solenoid valavu siyiyatsidwa (nthawi zambiri imatsegulidwa) kapena valavu yolumikizira imakakamira
Yankho: Yang'anani chingwe chamagetsi kuti muwone ngati magetsi alumikizidwa; Ngati zachilendo, zimasonyeza kuti valavu ya slide ikhoza kutsekedwa, ndipo mbali zolakwika ziyenera kukonzedwa kapena kusinthidwa.
