How Training in Machinery Lubrication Improves Turbomachinery Lubrication Practices Introduction Turbomachinery lubrication is not just “putting oil in a machine.” For turbines, compressors, turbo-pumps, gearboxes, expanders, generator bearings, seal-oil systems, and control-oil systems, lubrication is a reliability barrier. The oil must create the correct film thickness, remove heat, prevent corrosion, carry contaminants to filters, separateContinueContinue reading “How Training in Machinery Lubrication Improves Turbomachinery Lubrication Practices”

Why Electrostatic Filtration Fails in Oils with High Acid Number and High Water Content
Why Electrostatic Filtration Fails in Oils with High Acid Number and High Water Content Electrostatic oil filtration is effective only when the oil behaves like a good electrical insulator. In a healthy hydraulic, turbine, transformer, or circulating oil system, the base oil has relatively low conductivity, so a strong electric field can be maintained acrossContinueContinue reading “Why Electrostatic Filtration Fails in Oils with High Acid Number and High Water Content”
Antioxidant Additive Packages in Turbine Oils: Phenolic, Aminic, and Mixed Systems
Antioxidant Additive Packages in Turbine Oils: Phenolic, Aminic, and Mixed Systems Key point upfront In formal lubricant chemistry, phenolic antioxidants and aminic antioxidants are both usually “primary antioxidants” because they mainly stop free-radical chain oxidation. A true secondary antioxidant is normally a peroxide decomposer, such as a phosphite, sulfide, dithiocarbamate, sulfurized phenol, or ZDDP-type chemistry in fluids where zincContinueContinue reading “Antioxidant Additive Packages in Turbine Oils: Phenolic, Aminic, and Mixed Systems”
Designing Bearing Surfaces for Less Varnish
Khash was asked: What is Babbitt ? Can’t its material to be designed to attract less varnish ? discuss in details how these metals attract varnish and what changes are required to attract less , is it possible to coat them or have a metallurgy that is less polar ? Khash Replied: 1. What BabbittContinueContinue reading “Designing Bearing Surfaces for Less Varnish”

Electrical Faults in Turbomachinery – Why They Happen, How They Attack Journal Bearings, and How They Appear in Oil Analysis
Electrical Faults in Turbomachinery: Why They Happen, How They Attack Journal Bearings, and How They Appear in Oil Analysis Most maintenance and reliability engineers are familiar with VFD-driven electric motors and the classic bearing current failure mode known as fluting in rolling bearings. But in turbomachinery, especially large compressors, steam turbines, gas turbines, turbo-generators, and motor-driven centrifugal machines, electricalContinueContinue reading “Electrical Faults in Turbomachinery – Why They Happen, How They Attack Journal Bearings, and How They Appear in Oil Analysis”
How Lubrication and Vibration Are Linked in Turbomachinery
How Lubrication and Vibration Are Linked in Turbomachinery A practical reliability perspective from Khash In turbomachinery, lubrication and vibration are often treated as two separate disciplines. The oil analysis engineer looks at viscosity, water, particle count, TAN, MPC, RULER, demulsibility, and oxidation. The vibration analyst looks at spectrum, waveform, orbit, phase, 1X, 2X, sub-synchronous vibration,ContinueContinue reading “How Lubrication and Vibration Are Linked in Turbomachinery”

Separate Seal Oil and Lube Oil Consoles in Wet-Seal Gas Compressors
Separate Seal Oil and Lube Oil Consoles in Wet-Seal Gas Compressors A practical maintenance and oil analysis article from Khash’s perspective In many process gas compressors, especially older centrifugal compressors handling natural gas, refinery gas, synthesis gas, sour gas, or wet process gas, the machine may have two separate oil systems: Lube oil system: for bearings,ContinueContinue reading “Separate Seal Oil and Lube Oil Consoles in Wet-Seal Gas Compressors”
How Khash Would Compare Turbine Oils
Turbine Engineer asked me : All companies like Shell, TOTAL, Mobil , Chevron etc are global lubricant manufacturer , do we need to really care about technical comparison or leave it to the procurement to buy the cheapest among all ? Khash , How would you compare them technically. Khash: By looking at Datasheet onlyContinueContinue reading “How Khash Would Compare Turbine Oils”
