Cylinder oil composition

Cylinder oil is suitable for lubricating the cylinders of steam engines as well as the sliding parts that come into contact with steam; it can also be used for lubricating other mechanical components that operate under high temperatures and at low speeds. It is formulated by using mineral base oils to which various additives have been added. Component analysis generally employs spectroscopy (UV, IR, NMR) ； Chromatography (gas chromatography, liquid chromatography, ion chromatography) ； Mass spectrometry (mass spectrometer, GC-MS, LC-MS) ； Spectra (fluorescence spectrum, diffraction spectrum) ； Thermographic techniques (thermogravimetry, differential scanning calorimetry) are used for a comprehensive analysis of samples. By combining various separation and analysis methods, qualitative and quantitative analysis of the different components in the sample can be carried out, thereby determining the structure of these components and providing a thorough understanding of the sample. 【Performance requirements for cylinder oil】 Higher viscosity: The viscosity of cylinder oil must be sufficient to maintain a strong oil film at the high temperatures in the cylinders, thereby preventing sticking and providing sealing. Good lubricity: Cylinder oil should provide good lubrication on the hot cylinder surfaces and have the ability to resist washing out by water vapor. Low volatility and high flash point: This ensures that the oil does not lose its lubricating and sealing properties due to vaporization at high temperatures. Good thermal oxidation stability: Under high-temperature and oxygen exposure, the oil should not oxidize or deteriorate easily, nor should it gel or form carbon deposits. Good anti-emulsification properties: Condensate water often gets mixed into cylinder oil, so it is necessary to have good anti-emulsification properties, allowing the condensate water to be separated from the oil without emulsification occurring.
