    挖沙船的機油如何選擇統一重工告訴您
      我公司是從事挖沙船生產的專業服務廠家,并且堅持“統一目標,統一服務,統一質量”的經營理念。挖沙船在使用過程中自然會消耗機油,好的機油會降低發動機的磨損,延長挖沙船的使用壽命,讓挖沙船的使用效率更高,今天就跟大家講一下如何選擇挖沙船的機油:
        ①有機酸。它使金屬表面受到腐蝕,尤其鉛青銅軸承所受到的腐蝕最為嚴重。

     ?、谀z質。它是由機油在高溫、高壓下一部分碳氫化合物氧化而成。聚集在潤滑油膜中的膠質,在高溫作用下形成漆狀的粘稠物,使活塞環粘結在環槽內而失去作用。

     ?、鄯e炭。膠質氧化沉淀而形成的瀝青質在高溫下進一步氧化形成積炭,這些炭會形成熾熱點,使零件過熱,磨損加劇。
     ?、苡湍?。機油中混入水分后,不僅使機油乳化形成乳濁液,而且金屬磨屑還會與機油中的酸性氧化物起化學反應生成鐵皂。乳濁液中的油、水、鐵皂,以及機油中的灰塵、金屬磨屑和機油、柴油的各種氧化物相互混合形成油泥。油泥凝結在油管中,不僅增大機油流動的阻力,甚至阻塞油路,使柴油機的潤滑系統失去作用。

      以上就是挖沙船在選擇機油時需要注意的一些地方,希望可以幫到大家,歡迎來電咨詢。

      Our company is engaged in dredging sand production professional service manufacturers, and adhere to the "unified goal, unified service, unified quality" business philosophy. Dredging sand in the process of use naturally consumes oil, good oil will reduce engine wear, prolong the service life of dredging vessels, so that the use of dredging sand more efficient, today with you to talk about how to choose the oil dredging sand:
    ① organic acids. It has corroded the surface of the metal, especially the corrosion of lead bronze bearings.
    ② gum. It is made from the oxidation of oil at high temperature and high pressure. The gum gathered in the lubricating oil film, formed the lacquer viscous material under the high temperature, so that the piston rings bonded in the annular groove and lost their role.
    ③ carbon deposition. The asphaltene formed by oxidative precipitation of glial is further oxidized at elevated temperatures, which will form hot spots, overheating and abrasion of the parts.
    ④ sludge. The oil is mixed with moisture, not only to make oil emulsion formation emulsion, and metal debris will also with the oil in the acid oxides of chemical reactions to generate iron soap.    The oil, water, iron soap, and dust in the emulsion, metal shavings and oil, diesel oil are blended with each other to form sludge. Sludge condensation in the tubing, not only increase the oil flow resistance, even blocking the circuit, so that the lubricating system of the diesel engine loses its effect.
    Above is to dig sand in the selection of oil needs to pay attention to some places, hope can help everyone, welcome to inquire.
