Extreme Pressure & Lubricity Tester
Summery
The Model EP-212 Combination EP (Extreme Pressure) and Lubricity Tester is a high-quality instrument designed to measure the lubricating quality of drilling fluids, provide data to evaluate the type and quantity of lubricating additives that may be required, and predict wear rates of mechanical parts in known fluid systems.
EP/Lubricity Tester capabilities
Measure the lubricating quality of drilling fluids
Provide data to evaluate the type and quantity of lubricating additives that may be required
Predict wear rates of mechanical parts in known fluid systems
Measure of friction is a requirement for the determination of the film strength of a lubricant, for bit bearing wear, as is obtained in EP test and for the determination of torque or drag of the drill pipe as determined in the lubricity test.
EP (Extreme Pressure Test)
This test produces an indication of the film strength of the fluid being tested by applying a measured force to a torque-sensitive bearing cup with the torque arm. The EP test is typically run at a high shear rate, 1,000 RPM, with fluid pressures ranging from 5,000 to 100,000 PSI between the steel surfaces.
Lubricity (Surface to Surface Drag Test)
The more common lubricity test measures fluid resistance of various lubricating additives. For the standard lubricity coefficient test, 150 in-pounds of force (the equivalent of 5,000 to 10,000 PSI pressure on the intermediate fluid) is applied between two hardened steel surfaces, a block, and a ring rotating at 60 RPM.
Features
1. Digital Control - The digital control board provides more accurate data than older, analog methods.
2. User-Friendly Interface - The simple, intuitive interface makes testing quick and easy. Functions include pre-set speeds (60, 200, 600, and 1000 RPM), manual speed control, and torque zeroing.
3. Maximum Speed - 1,000 RPM
4. Maximum Torque - 600 inch-pounds
