PC60-7 Valavu yozungulira chitetezo cha valve Excavator chowonjezera chothandizira

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.

Chiweruzo cha zolakwa wamba za excavator

Cholakwika 1: Utsi wabuluu kuchokera ku injini

Choyamba, dziwani ngati mafuta a injini ndi aakulu kwambiri m'zaka zaposachedwapa, ngati ndi choncho, mwina chifukwa injini imawotcha mafuta. 2. Ngati mafuta sakuwonjezeka, yang'anani supercharger.

Malangizo: Utsi wa buluu wa injini, nthawi zambiri chifukwa cha silinda ya silinda ndi kuvala mphete ya pisitoni yokhala ndi chilolezo chochulukirapo kapena kuyenda kwa axial ndi supercharger seal wear ndi yayikulu kwambiri, chonde lemberani woyimira makasitomala.

Cholakwika 2: Kugwiritsa ntchito mafuta ambiri.

Chizindikiro: 1. Yang'anani kutayikira ndi utsi wakuda. 2. Ngati mkhalidwe uli wabwinobwino, yang'anani mapaipi onse olowera mpweya kuti achuluke fumbi. 3. Ngati palibe kusonkhanitsa fumbi, chonde konzekerani kopi ya mita yogwiritsira ntchito mafuta (fomu iyi ingapezeke kuchokera kwa woimira makasitomala).

Lingaliro: 1. Ngati fumbi la cylinder inlet likupezeka, chonde tumizani ku msonkhano kuti mukonze. Makinawa ali mumkhalidwe wabwinobwino, ndipo ngati apitilira muyezo, amafunika kufufuzidwa, kuwunikiridwa ndi kukonzedwa.
