Why is turbine oil also called “turbo oil” and other names? I. Why turbine oil is also called “turbo oil” Ø Origin: Turbine oil is commonly referred to as turbo oil because “turbo” is the English transliteration of the word “turbine” for turbines. Ø Purpose: It is mainly used to lubricate the sliding bearings, reduction gears, and governors in steam turbine generators and hydro turbine generators, as well as as a working medium in hydraulic systems. II. Turbine oil emulsification issue Ø Effects: Emulsification destroys the oil film, increases friction between components, leads to bearing overheating, accelerates corrosion of metal parts and deterioration of the oil quality, and facilitates the formation of sludge. Ø Reason: The oil lacks sufficient anti-emulsification properties; it contains emulsifiers and water, with the emulsifiers possibly arising from the degradation of the oil or from surfactants introduced from outside. III. Problem of excessive particle size Ø Impact: Excessive particle size can clog the system’s filters, and hard particles can cause severe wear on the shaft journals and bearings. Ø Source: Solid particles include metal shavings, metal oxides, dust, fibers, and sludge, which mainly arise from the wear of components such as oil pumps and the degradation of the oil itself. IV. Problem of excessive foam Ø Impact: Excessive foam can affect the oil supply pressure of the oil pump, damage the oil film, leading to wear; in severe cases, oil may overflow from the top of the tank, posing a threat to the safe operation of the equipment. Ø Reasons: include foam-forming components resulting from oil degradation, the depletion of the oil’s natural antifoam agents, residues of cleaning agents, and the absorption of impurities into the lubricant tank under negative pressure. V. Problem of excessive acid value Ø Hazards: An increased acid value indicates that the oil has degraded, producing acidic substances that can corrode metal components and affect various properties of the oil. Ø Reason: First, the quality of the oil is poor, resulting in a reduced antioxidant capacity ； Second, there is overheating or localized overheating in the oil system. In summary, the quality and performance of turbine oil are crucial for the stable operation of the unit. During use, it is necessary to closely monitor parameters such as oil emulsification, particle size, foam, and acid value, and take timely measures to prevent the deterioration of the oil quality and ensure the safe operation of the unit.
