1. Vavu ikhale yoyera

Sungani mbali zakunja ndi zosuntha za valve zoyera, ndipo sungani kukhulupirika kwa utoto wa valve. Pamwamba pa valavu, ulusi wa trapezoidal pa tsinde ndi mtedza wa tsinde, gawo lotsetsereka la mtedza wa tsinde ndi bulaketi ndi zida zake zotumizira, nyongolotsi ndi zigawo zina ndizosavuta kudziunjikira dothi lambiri monga fumbi, madontho amafuta. ndi zotsalira zakuthupi, zomwe zimayambitsa kuwonongeka ndi dzimbiri ku valve.

Choncho, valve iyenera kukhala yoyera nthawi zonse. Nthawi zambiri, fumbi pa valavu ayenera kusesa ndi burashi ndi wothinikizidwa mpweya, kapena kutsukidwa ndi mkuwa waya burashi mpaka processing pamwamba ndi zofananira pamwamba zimasonyeza zitsulo luster, ndi utoto pamwamba amasonyeza mtundu woyamba wa utoto. Msampha wa nthunzi uyenera kuyang'aniridwa kamodzi pachaka ndi munthu wopatsidwa ntchito; Tsegulani pulagi yapansi ya valve yothamanga ndi msampha wa nthunzi nthawi zonse kuti muyeretsedwe, kapena muchotseni nthawi zonse kuti muyeretsedwe, kuti valavu isatsekedwe ndi dothi.

2.Sungani valve mafuta

Kupaka valavu, ulusi wa trapezoidal wa valavu, magawo otsetsereka a mtedza wa tsinde ndi bulaketi, ma meshing a malo onyamula, zida zotumizira ndi zida za nyongolotsi, ndi mbali zina zofananira ziyenera kusungidwa ndi mafuta abwino kwambiri. miyezo, kuti muchepetse mikangano komanso kupewa kuvala kogwirizana. Pazigawo zopanda chizindikiro cha mafuta kapena jekeseni, zomwe zimakhala zosavuta kuwonongeka kapena kutayika pakugwira ntchito, pulogalamu yonse ya mafuta odzola iyenera kukonzedwa kuti iwonetsetse njira ya mafuta.

Zigawo zopaka mafuta ziyenera kuthiridwa mafuta pafupipafupi malinga ndi momwe zinthu zilili. Valavu yomwe imatsegulidwa kawirikawiri ndi kutentha kwakukulu ndi yoyenera kuwonjezereka kamodzi pa sabata mpaka mwezi; Osatsegula nthawi zambiri, kutentha sikokwera kwambiri valavu yowonjezera yowonjezera nthawi imatha kukhala yayitali. Mafuta amaphatikizapo mafuta a injini, batala, molybdenum disulfide ndi graphite. Mafuta a injini si oyenera valavu yotentha kwambiri; Batala sakwanira, mwina. Amasungunuka ndi kutha. Vavu yotentha kwambiri ndiyoyenera kuwonjezera molybdenum disulfide ndikupukuta ufa wa graphite. Ngati mafuta ndi mafuta ena amagwiritsidwa ntchito pazigawo zokometsera zomwe zimawonekera kunja, monga ulusi wa trapezoidal ndi mano, ndizosavuta kuipitsidwa ndi fumbi. Ngati molybdenum disulfide ndi graphite ufa amagwiritsidwa ntchito popaka mafuta, sikophweka kuti aipitsidwe ndi fumbi, ndipo zotsatira zenizeni za mafuta zimakhala bwino kuposa batala. Graphite ufa siwophweka kuti ugwiritsidwe ntchito nthawi yomweyo, ndipo ungagwiritsidwe ntchito ndi mafuta ochepa a makina kapena madzi osinthidwa phala.

Valve ya pulagi yokhala ndi chisindikizo chodzaza mafuta iyenera kudzazidwa ndi mafuta molingana ndi nthawi yoikidwiratu, apo ayi ndizosavuta kuvala ndikutuluka.

Kupatula apo, sikuloledwa kugogoda, kuthandizira zinthu zolemetsa kapena kuyimirira pa valve kuti valavu isakhale yodetsedwa kapena kuwonongeka. Makamaka sanali zitsulo chuma mauna zitseko ndi mavavu kuponyedwa chitsulo, ayenera kuletsedwa.

Pitirizani kukonza zida zamagetsi. Kukonzekera kwa zida zamagetsi sikuyenera kukhala osachepera kamodzi pamwezi. Zosungiramo zosungiramo zikuphatikizapo: pamwamba pake adzatsukidwa popanda kusonkhanitsa fumbi, ndipo zipangizo sizidzaipitsidwa ndi madontho a nthunzi ndi mafuta; Kusindikiza pamwamba ndi mfundo zikhale zolimba ndi zolimba. Palibe kutayikira; Magawo opaka mafuta adzadzazidwa ndi mafuta molingana ndi malamulo, ndipo mtedza wa tsinde la valve udzathiridwa ndi mafuta; Mbali ina ya zida zamagetsi idzakhala yosasunthika popanda kulephera kwa gawo, switch switch ndi relay yotenthetsera sizidzagwedezeka, ndipo chidziwitso chowonetsera nyale chizikhala cholondola.
