DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester 1. Introduction When there is relative motion between two contacting bodies, frictional forces that resist motion always come into play. Frictional resistance to rotation of the drill string is called torque, and is especially enhanced when drilling a deviated hole. Many different materials, such as graphite, fine mica, and diesel or crude oil, have been used as mud additives to improve lubricity. Since evaluation of the various materials cannot realistically be done on a drilling rig, a lubricity test...

EP (Extreme Pressure Lubricity/ Lubricity (Surface to Surface Film Strength Teat) Drag Test) Usually higher shear rate 1000 RPM for coefficient test- Here fluid pressures run from 5,000 to pressure (farce) at various speeds at which film breaks and galling occurs can be measured and improved additives Lubricity additives to lessen drag losses can be easily tested. The wear on a part can be predicted by making block or both ring and block of material used In part, and running in fluid expected in application. The procedure for this test well as in this instruction.

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester Document Conventions The following icons are used as necessary in this instruction manual. WARNING! Describes an unsafe condition or practice that if not corrected, could result in personal injury or threat to health. ELECTRICITY WARNING! Alerts the operator that there is risk of electric shock. HOT SURFACE! Alerts the operator that there is a hot surface and that there is risk of getting burned if the surface is touched. Machine Hazard Make sure the machine is unplugged when cleaning or moving...

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester These procedures will determine if it is necessary to partially disassemble the machine for a complete calibration. WARNING! PROCEDURES OF INVOLVE OPERATING THE MACHINE WITH THE BELT GUARD AND CONTROL PANEL REMOVED. THIS EXPOSES UNPROTECTED, HIGH VOLTAGE TERMINALS. TOUCHING OR ALLOWING THESE TERMINALS TO TOUCH THE MACHINE OR WORK SURFACE CAN CAUSE DAMAGE AND INJURY. ALSO, THE PRONY BRAKE IS A DYNAMIC BRAKING TOOL WHICH IF NOT HANDLED CAREFULLY CAN GRAB ONTO SHAFT AND SWING UPWARDS TOWARDS OPERATOR WHILE...

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester 3. Features and Specifications Motor and Belt Drive The motor's speed is directly variable by voltage with a maximum of 1000 RPM. The speed is reduced at the V-belt sheaves by a factor of 1:1.6. Lubricity Test Blocks and Rings The lubricity test blocks and rings are hardened steel components between which the fluid lubricity is tested. These components must be matched and calibrated together before performing a test. The ring will wear a uniform wear pattern in the block during calibration. There are...

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester 4. Installation The Model EP-212 EP/Lubricity Tester is easily mounted on a laboratory countertop. A 220 VAC power source is the sole service required for this unit. The Model EP-212 requires 5 A current at 220 VAC. 5. Operation 5.1 Lubricity Test 1. Clean the lubricity test ring (with a flat outer surface) and the lubricity test block (with a concave groove on one side) with Acetone and rinse them thoroughly with deionized water. All parts of the machine in the sample area must be clean before starting...

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester Using a wrench, secure the test ring retainer nut.Make sure the ring seats squarely on the taper of the shaft. Note: 3. Turn on the power and let the machine run for approximately 15 minutes. 4. Place the lubricity test block in the block holder with the concave side facing out and align it with the test ring. 5. Set the motor speed to 60 RPM. 6. After the unit has been running for 15 minutes, zero the torque reading Run the unit approximately 5 more minutes and adjust again if required. 7. Fill the...

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester arm reads 150 inch-pounds. Never apply torque to the test ring unless it is submerged in fluid. 9. Let the machine run for 5 minutes and then record the torque reading.The torque reading should be 34 ± 2 (between 32 and 36). If the torque reading is outside this range, see the "Standardizing the Test Block". Otherwise, proceed to step 10. 10. Zero the torque reading. Then, lower the cup stand and discard the fluid. Wipe any remaining fluid from the sample cup, block, block holder, and test ring. 11. Mix...

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester AVERAGE READING:

DRILLNG FLUID TESTING INSTRUMENTATION EP(Extreme Pressure) and Lubricity Tester Follow these steps to calculate the Film Strength of the test fluid: 1. To measure the scar length on the block, use a magnifier calibrated to read 0.005" (0.0127 cm). Place the magnifier at the center of the scar parallel to the edges. This will allow you to obtain the average width of the scar. Record the scar measurement in inches. 2. To calculate the pressure on the block: A. Begin by computing the total area of the scar on the block. Multiply the width of the scar (in inches) by the length (in...
