船舶润滑油是指用于船舶设备机械的润滑油,从而对船舶起到养护润滑的作用。船用润滑油一般有:船用中速机油,船用系统用油,船用气缸油,船用发动机油等。

中速发动机的工作原理与高速发动机基本相同,一般船用中速机可多到20个缸,成对排列或V型,经减速齿轮箱与推进器连接,润滑油润滑活塞、轴承等,同时亦能润滑齿轮箱,但船用中速筒状活塞发动机特点是燃用劣质燃料,因此和一般高速机相比,船用中速机油有其特殊要求。它应兼船用气缸油和船用系统油双重性能的要求。

中速筒状活塞柴油机油性能:润滑油膜有足够的承载能力,以保证在边界润滑状态下降低磨损;优良的热氧化安定性,尽量少的生成漆膜、积炭和油泥;根据燃油的硫含量,油品必须具备足够的总碱度,以中和酸性物质防止腐蚀磨损;优良的清净分散性,中速机作为船用主机,动率大,发动机在工作过程中润滑油总是处在循环、离心、净化状态。因此对油品的清净分散性提出了更高要求,不能在离心净化过程中使油品的清净分散性降低。此外,中速机油在工作过程中直接与高温的活塞、缸套以及燃用劣质燃料而产生更加恶劣的燃气接触。因此,中速机高温沉积物生成倾向更为严重,从而对中速机油的高温清净分散性提出了更高要求。对船用中速机既要有优良的清净分散性,同时又要求油品在离心净化过程中不降低其清净分散性;抗水性,一般对船用油都提出了这个要求,而中速机油由于要中和劣质燃料燃烧而产生的酸性产物,因此需其油品有一定TBN。而高碱性添加剂加入不利于油品的抗水性,所以更要求其有良好的抗水性。

性能特点:良好的碱值保持性和防锈性能,能够有效抑制因含硫燃料燃烧而产生的酸性。物质的腐蚀,防止机件的锈蚀和腐蚀,并对发动机提供有效保护;优良的抗氧化性能及热稳定性,降低油品的氧化速度,延长使用时间;优良的清净分散性,有效防止高温积炭和低温油泥的生成,保持发动机清洁;良好的分水性能,能迅速将进入油中的水分分离,避免油品乳化。

应用范围:船用中速机油4030适用于使用硫含量3.5%以下的船用中速筒状活塞柴油,发动机、大型船舶辅助发动机、陆用柴油发电机组的润滑;满足主机厂的性能要求,广泛应用于众多大型船舶;船用中速机油4030适用于新发动机润滑,以有效减少能耗。

注意事项:中速机油的贮存和运输过程中要注意尽可能在室内存放,做到防水防潮;在使用过程中尽可能不与其他品牌或其他种类的产品混合使用。

安全和健康:根据现有信息,按照化学品安全技术说明书(MSDS)的推荐,此产品用作特定用途时,不会对健康有副作用。
