Today is an important day in my career that I am not an employee but I would spending time on my dream of being a full time trainer and consultant in Lubrication by Noria Corporation. Wrote below to share with you Khash feelings. Letter of Recommendation - Khashayar HajiahmadDownload Today marks a major milestone inContinue reading "Today marks a major milestone in Khash career"

Practical technical article Executive answer Yes — inspection ports can be integrated into turbomachinery bearing return lines to assess the varnish potential of the passing hot oil, but the correct design is not a simple sight glass. The practical design is a bearing-material witness inspection port: a visible, oil-wetted inspection chamber containing a removable coupon made from theContinue reading "Can Inspection Ports Be Integrated in Turbomachinery Bearing Return Lines to Assess Varnish Potential Using Bearing-Material Witness Surfaces?"

Before I attend tomorrow webinar by Atten2 ( https://atten2.com/en/ ) wanted to share all I know on this matter Unplanned Downtime Starts Before Failure: Aeroderivative Turbines, Oil Chemistry, and the Lubrication Blind Spot By Khash — MLE, CLS, MLA III, MLT II, VIM, VPR Aeroderivative gas turbines are built for speed, flexibility, and high powerContinue reading "Unplanned Downtime Starts Before Failure: Aeroderivative Turbines, Oil Chemistry, and the Lubrication Blind Spot"

An Oil And Gas industry Reliability Engineer asked me.: Can you help me while am I doing RCM study on the lubricated components of a turbomachinery? I replied back with below content: Can We Do an RCM Study on the Lubricated Components of Turbomachinery? By Khash Yes, you absolutely can do an RCM study onContinue reading "Can We Do an RCM Study on the Lubricated Components of Turbomachinery?"

THE VARNISH WORLD CUP Turbine Oil Varnish Removal Championship A turbine plant enters the biggest reliability match of the year: TEAM CLEAN OIL vs. FC VARNISH The players are: Khash — Head Coach / Lubrication StrategistMaintenance Team — Defenders and field techniciansReliability Team — Midfield analysts and trend readersOEM — Referee / VAR technical authorityProcurement — Goalkeeper controlling budget andContinue reading "THE VARNISH WORLD CUP – Khash Comic Series"

A turbine engineer sent me above photos and asked Khash ==> Journal or Bearing ? Which place varnishing happens first ? Needing a detailed article on it  Khash Replied Direct answer The bearing is the stationary sleeve/pad/shell around it. In a hydrodynamic/plain journal bearing, the shaft journal is supported by an oil wedge, and under correct operationContinue reading "Journal or Bearing ? Which place varnishing happens first ?"

Advanced Tribology in Turbomachinery Lubrication Same article in two levels: engineering level + 10-year-old level 1. Why tribology matters in turbomachinery Advanced version:Turbomachinery includes turbines, compressors, turbochargers, pumps, and high-speed generators. These machines rotate extremely fast, so the shaft must be supported without metal surfaces rubbing directly. Tribology—the science of friction, wear, and lubrication—is thereforeContinue reading "Advanced Tribology in Turbomachinery Lubrication Same article in two levels: engineering level + 10-year-old level"

All Possible Sampling Points in Turbomachinery: Why Each Location Can Show a Different MPC Varnish Potential Level Oil analysis is only as good as the sample that reaches the lab. In turbomachinery lubrication systems, this point is especially important because the oil is not chemically or physically identical everywhere in the system at the sameContinue reading "All Possible Sampling Points in Turbomachinery: Why Each Location Can Show a Different MPC Varnish Potential Level"

Delta L and the Black MPC Patch in Turbine-Oil Varnish Potential Testing 1. What MPC varnish testing is measuring The common varnish potential test for turbine oils is Membrane Patch Colorimetry, or MPC, covered by ASTM D7843. The method extracts insoluble contaminants from an in-service turbine-oil sample onto a membrane patch, then measures the patch color withContinue reading "Delta L and the Black MPC Patch in Turbine-Oil Varnish Potential Testing"
