1. Kugwiritsa ntchito madzi ozizira:
(1) Madzi osungunula, madzi apampopi, madzi amvula kapena madzi amitsinje aukhondo ayenera kugwiritsidwa ntchito ngati madzi ozizira a injini za dizilo. Madzi akuda kapena olimba (madzi achitsime, madzi amchere, ndi madzi ena amchere) sayenera kugwiritsidwa ntchito popewa kukulitsa ndi kukokoloka kwa zomangira masilinda. Pokhapokha pamadzi olimba, angagwiritsidwe ntchito pokhapokha atafewetsa ndi kubwezeretsanso ndalama.
(2) Pothira madzi m’thanki yamadzi, makina ozizirawo sangadzazidwenso nthawi imodzi. Injini ya dizilo ikatha, iyenera kuwonedwanso. Ngati sichikukwanira, makina ozizirira ayenera kuwonjezeredwa. Njira yozizira yolowera madzi ili pamwamba pa chivundikiro chaching'ono chapamwamba cha bulldozer.
(3) Ngati akugwira ntchito mosalekeza, madzi ozizira ayenera kusinthidwa maola 300 aliwonse kapena kupitirira apo. Pali zitseko zisanu zodula madzi za makina ozizirira a injini ya dizilo ya bulldozer: 1 ili pansi pa thanki yamadzi; 2 ili pansi pa chozizira chamafuta oziziritsa madzi a injini ya dizilo; 3 ili kumapeto kwa injini ya dizilo, pa mpope wamadzi wozungulira; 4 ili kumanzere kwa chotengera chosinthira, pa injini ya dizilo; M'munsi mapeto a thanki madzi potulutsira chitoliro.
Ngati mukufuna ma bulldozer, chonde dinani apa!
2. Chithandizo cha masikelo:
Maola 600 aliwonse, makina ozizira a injini ya dizilo amayenera kuthandizidwa ndi sikelo.
Pochiza matenda, nthawi zambiri amatsukidwa ndi njira yoyeretsera acidic poyamba, kenako amachotsedwa ndi madzi amchere amchere. Kupyolera muzochitika za mankhwala, sikelo yosasungunuka madzi imasandulika mchere wosasungunuka m'madzi, womwe umachotsedwa ndi madzi.
Njira yeniyeni yogwirira ntchito ndi iyi:
(1) Chotsani thermostat ya dongosolo lozizira.
(2) Yambitsani injini ya dizilo ndikukweza kutentha kwa madzi mpaka 70 ~ 85C. Pamene mulingo woyandama ukukwera, zimitsani moto nthawi yomweyo ndikumasula madziwo.
(3) Thirani madzi oyeretsera okonzeka acidic mu thanki yamadzi, yambani injini ya dizilo, ndikuyendetsa pa 600～800r/min kwa mphindi pafupifupi 40, ndiyeno mutulutse madzi oyeretsera.
Kukonzekera njira yothetsera asidi:
Onjezani zidulo zitatu m'madzi oyera motere: hydrochloric acid: 5-15%, hydrofluoric acid: 2-4%,
Glycolic acid: 1 mpaka 4%. Mukasakaniza bwino, zitha kugwiritsidwa ntchito.
Komanso, ngati n'koyenera, mlingo woyenera wa polyoxyethylene alkyl allyl ether akhoza kuonjezedwa kusintha permeability ndi dispersibility wa lonse. Kutentha kwa madzi oyeretsera asidi sikuyenera kupitirira 65 ° C. Kukonzekera ndi kugwiritsa ntchito madzi oyeretsera kungatanthauzenso zomwe zili mu buku la "135" mndandanda wa injini ya dizilo ndi kukonza.
(4) Kenako bayani 5% sodium carbonate aqueous solution kuti muchepetse njira yoyeretsera asidi yomwe yatsala munjira yozizirira. Yambitsani injini ya dizilo ndikuyisiya pang'onopang'ono kwa mphindi 4 mpaka 5, kenako zimitsani injiniyo kuti mutulutse njira yamadzi ya sodium carbonate.
(5) Pomaliza, bayani madzi oyera, yambitsani injini ya dizilo, ipangitseni kuthamanga kwambiri komanso nthawi zina liwiro lotsika, tsukani njira yotsalira munjira yozizira ndi madzi oyera, zungulirani kwakanthawi, kenako zimitsani injini ndikumasula madzi. Tsatirani izi ndikubwereza ntchitoyo kangapo mpaka madzi okhetsedwa asalowerere ndikuyang'ana pepala la litmus.
(6) Pakadutsa masiku 5 mpaka 7 mutatsuka, madzi ozizira ayenera kusinthidwa tsiku lililonse kuti sikelo yotsalayo isatseke chipata cha kukhetsa madzi.
3. Kugwiritsa ntchito antifreeze:
Pazizizira kwambiri komanso kutentha kochepa, antifreeze angagwiritsidwe ntchito.
Ngati mukufuna zida zopangira bulldozer, chonde dinani apa!
