HFRR

 

  HFRR:  High Frequency Reciprocating test Rig

 The High Frequency Reciprocating Test method (s) measures the lubricity, or ability of  a fluid to affect friction between and wear to surfaces in relative motion under load.   

HFRR Applications:

• Evaluation of new Diesel, Gasoline & Lubricant additives Determination of optimum additive dosages for raw fuels
• Quality for outgoing products & incoming materials to ensure conformity with specs.
• Boundary friction coefficient measurements for automobile fuel economy modeling

 

 THE SYSTEM

 The complete system comprises of:  Mechanical Test Unit
With upper    and lower specimen holders, with standard test specimen/s
 (6 mm ball  & 10 mm disc/plate)

• Data Acquisition & Control System
Controls Stroke length,     reciprocation frequency,     temperature. 
Logs all test measurements to spreadsheet
