1. Sungani valavu yoyera

Sungani mbali zakunja ndi zoyenda za valavu kukhala zoyera, ndikusunga umphumphu wa utoto wa valavu. Mbali ya pamwamba pa valavu, ulusi wa trapezoidal pa tsinde ndi tsinde la nati, gawo lotsetsereka la tsinde la nati ndi bulaketi ndi zida zake zotumizira, nyongolotsi ndi zinthu zina ndizosavuta kusonkhanitsa dothi lambiri monga fumbi, madontho a mafuta ndi zotsalira za zinthu, zomwe zimapangitsa kuti valavuyo iwonongeke komanso iwonongeke.

Chifukwa chake, valavu iyenera kukhala yoyera nthawi zonse. Kawirikawiri, fumbi lomwe lili pa valavu liyenera kutsukidwa ndi burashi ndi mpweya wopanikizika, kapena kutsukidwa ndi burashi ya waya wamkuwa mpaka pamwamba pake ndi pamwamba pake ziwonetse kunyezimira kwachitsulo, ndipo pamwamba pake pa utoto ziwonetse mtundu waukulu wa utoto. Chotsukira nthunzi chiyenera kuyang'aniridwa kamodzi pa nthawi iliyonse ndi munthu wopatsidwa ntchito yapadera; Tsegulani pulagi yapansi ya valavu yotsukira ndi chotsukira nthunzi nthawi zonse kuti chiyeretsedwe, kapena chichotseni nthawi zonse kuti chiyeretsedwe, kuti valavu isatsekedwe ndi dothi.

2. Sungani valavu yofewa

Kupaka mafuta pa valavu, ulusi wa trapezoidal wa valavu, magawo otsetsereka a stem nut ndi bracket, magawo olumikizirana a malo operekera mafuta, zida zotumizira ndi zida za nyongolotsi, ndi zina zofanana ziyenera kusungidwa ndi miyezo yabwino kwambiri yopaka mafuta, kuti achepetse kukangana kwapakati ndikuletsa kuwonongeka kwapakati. Pazigawo zopanda chizindikiro cha mafuta kapena injector, zomwe ndizosavuta kuwonongeka kapena kutayika zikugwira ntchito, pulogalamu yonse ya makina opaka mafuta iyenera kukonzedwa kuti zitsimikizire kuti mafuta akuyenda bwino.

Zigawo zopaka mafuta ziyenera kupakidwa mafuta nthawi zonse malinga ndi mikhalidwe inayake. Valavu yotsegulidwa nthawi zambiri yokhala ndi kutentha kwakukulu ndi yoyenera kudzaza mafuta kamodzi pa sabata mpaka mwezi; Musamatsegule nthawi zambiri, kutentha sikukwera kwambiri. Nthawi yodzaza mafuta ya valavu imatha kukhala yayitali. Mafuta opaka mafuta ndi mafuta a injini, batala, molybdenum disulfide ndi graphite. Mafuta a injini si oyenera valavu yotentha kwambiri; Batala sagwiranso ntchito. Amasungunuka ndikutha. Valavu yotentha kwambiri ndi yoyenera kuwonjezera molybdenum disulfide ndi ufa wopukuta wa graphite. Ngati mafuta ndi mafuta ena agwiritsidwa ntchito pazinthu zopaka mafuta zomwe zimawonekera kunja, monga ulusi wa trapezoidal ndi mano, n'zosavuta kuipitsidwa ndi fumbi. Ngati molybdenum disulfide ndi ufa wa graphite agwiritsidwa ntchito popaka mafuta, sizosavuta kuipitsidwa ndi fumbi, ndipo zotsatira zake zenizeni zimakhala bwino kuposa batala. Ufa wa graphite si wosavuta kuupaka nthawi yomweyo, ndipo ungagwiritsidwe ntchito ndi mafuta ochepa a makina kapena phala lokonzedwa ndi madzi.

Vavu yolumikizira yokhala ndi chisindikizo chodzaza mafuta iyenera kudzazidwa ndi mafuta malinga ndi nthawi yomwe yatchulidwa, apo ayi imakhala yosavuta kuvala ndikutulutsa madzi.

Kupatula apo, siziloledwa kugogoda, kuchirikiza zinthu zolemera kapena kuyima pa valavu kuti valavuyo isadetsedwe kapena kuwonongeka. Makamaka zitseko za maukonde zomwe si zachitsulo ndi mavalavu achitsulo, ziyenera kuletsedwa.

Sungani kukonza zida zamagetsi. Kukonza zida zamagetsi sikuyenera kukhala kochepera kamodzi pamwezi. Zomwe zili mkati mwake ziyenera kukonzedwanso: pamwamba pake payenera kutsukidwa popanda fumbi, ndipo zidazo sizidzadetsedwa ndi nthunzi ndi mafuta; Malo otsekera ndi malo ofunikira azikhala olimba komanso olimba. Palibe kutayikira; Zigawo zodzola ziyenera kudzazidwa ndi mafuta motsatira malamulo, ndipo nati ya tsinde la valve iyenera kudzozedwa ndi mafuta; Gawo la zida zamagetsi liyenera kukhala lopanda vuto lililonse popanda kulephera kwa gawo, chosinthira chowongolera ndi chosinthira kutentha sichiyenera kugwedezeka, ndipo chidziwitso chowonetsera nyali chiyenera kukhala cholondola.
