The difference between machine oil and turbine oil

Mechanical oils usually only contain antioxidant additives; they are now referred to as oils for total loss systems. Turbine oil possesses better antioxidant stability and anti-emulsification properties, and contains additional additives; it is primarily used in steam turbines and other applications that require highly refined lubricants. Also known as TSA turbine oil.

I’m also troubled by lubricant. Why are there so many different types of oil? ?

I believe that lubricants are selected by taking into account both the characteristics of the machine and the processing conditions.

Turbine oil is generally used in high-speed equipment

Mechanical oil should be relatively cheap, and it can be added in sufficient quantities to the process system without being recycled

Machinery oil: A lubricant of average quality, obtained from petroleum lubricant fractions through dewaxing, solvent refining, and clay treatment. Usually, only antioxidant additives are added. Mechanical oils are divided into high-speed mechanical oils and ordinary mechanical oils, which are used respectively for lubricating components in textile machinery spindles, ordinary machine tools, and other general machinery. They are classified according to their dynamic viscosity at 50°C. 　　Mechanical oil is now referred to as oil for fully loss systems. The former national standard GB443-64 specified that lubricating oils were classified into grades based on the average value of their dynamic viscosity at either 50°C or 100°C. The new national standard GB443-84 specifies that the central value of the dynamic viscosity of the lubricant at 40°C shall be used as the new grade designation for the lubricant. The actual dynamic viscosity of the lubricating oil should be within a deviation of ±10% of the central viscosity value. The comparison of new and old grades of oils (machine oils) commonly used in fully lossy systems is shown in the table below. 　　Comparison table of new and old grades as well as viscosity coefficient ranges for oils used in fully loss systems. The above-mentioned machine oils can be replaced with HL hydraulic oil, which yields better results; L-AN machine oils are produced only by small and medium-sized enterprises, while large enterprises generally do not produce them. 　　HL hydraulic oil (also known as general-purpose lubricant for machine tools) l) Specifications HL hydraulic oil is made from a neutral base oil with a high degree of refinement, to which antioxidant and rust-preventing additives have been added. HL hydraulic oil can be classified into six grades based on its dynamic viscosity at 40°C: 15, 22, 32, 46, 68, and 100. 　　2) Applications HL hydraulic oil is primarily used for lubricating the bearing housings, gearboxes, low-pressure circulation systems, or similar circulation systems in various machine tools where no special requirements are placed on the lubricant, and where the ambient temperature is above 0°C. Its service life can be more than doubled compared to mechanical oil. This product has good adaptability to rubber sealing, with a maximum operating temperature of 80°C. 　　3) Quality requirements 　　(l) Appropriate viscosity and good viscosity-temperature properties. It is required that the viscosity of the oil be little affected by temperature changes, so that such changes do not interfere with the proper operation of the hydraulic system. 　　(2) It has good rust resistance and oxidation stability. 　　(3) It has relatively ideal air release values, antifoaming properties, water repellency, and adaptability for rubber sealing. 　　4) Precautions for use 　　(l) Thoroughly clean the original hydraulic oil tank before use, removing residual oil, used oil, and sediment, etc., to avoid mixing it with other types of oil. 　　(2) This product is not suitable for specialized machine tools operating under harsh conditions with high lubrication requirements. For gear drives, hydraulic systems, and guide rails that have high requirements for oil quality, medium- and heavy-duty gear oil, anti-wear hydraulic oil, or HG hydraulic oil should be used. 　　(3) Using this oil in place of mechanical oil for lubricating the circulation systems of general-purpose machine tools and other similar mechanical equipment yields significant economic benefits; it extends the interval between oil changes and saves an average of 1/3 to 1/2 of the lubricant used. Turbine oil: “Turbine” is the English translation of the word for steam turbine. The difference between turbine oil and other lubricants lies in its superior antioxidant stability and resistance to emulsification. Used in steam turbines in power plants and in other applications that require high-quality lubricants, turbine oil is a type of oil suitable for use in turbine engines; it serves to lubricate, dissipate heat, and regulate speed. The term “turbine” is a transliteration of the English word “turbine,” which originates from the Latin word “turbo,” meaning a rotating object. Also known as a turbine or turbine. The main component of a turbine is the rotating element (rotor or impeller), which is mounted on the turbine shaft and has blades arranged evenly around the circumference. The energy possessed by the fluid is converted into kinetic energy as it flows through the nozzle; as the fluid passes over the rotor, it impacts the blades, causing the rotor to rotate and thereby driving the turbine shaft to spin. The turbine shaft drives other machinery directly or through a transmission mechanism to deliver mechanical work. 　　Turbine oil, also known as TSA turbine oil, is classified into various viscosity grades according to ISO standards, such as 32, 46, 68, and 100. Its density is generally determined through actual measurements and changes as the dynamic viscosity of the turbine oil changes. Those working in the chemical industry should understand that the key parameter for evaluating turbine oil is its dynamic viscosity; dynamic viscosity/density equals dynamic viscosity. The approximate density range for turbine oil is between 0.9 and 0.91. As a supplementary note, if the base oil is of the HC type, the density is roughly between 0.83 and 0.85. 1. Ordinary turbine oil is used in the lubrication systems of mechanical equipment such as steam turbines, hydraulic turbines, and generator bearings in power plants, ships, and other industrial applications. 　　2. Rust-resistant turbine oil, a specialized oil for power plant equipment; it can also be used for lubricating and sealing turbine and hydro turbine units in ships and other industries. It can be used as oil for equipment such as compressors and hydraulic systems that require a medium free of sulfides. The ambient temperature used should be no lower than 0°C. 　　3. Anti-ammonia turbine oil is suitable for the lubrication and sealing of centrifugal synthesis compressors, chillers, and turbine units in large-scale synthetic ammonia fertilizer plants. The operating temperature range is 50–55°C, while the ambient humidity range is –10–50°C; the 32D variant can be used within the range of –20–50°C.

Just use turbine oil; there’s no problem with that. It’s even better than mechanical oil, though it’s a bit more expensive
