Product Description

Preparation and Operation

  1. Polishing the Friction Wheel
    Before each test, the friction wheel must be polished with ordinary lubricating oil. Failure to do so will affect the accuracy of the test results.
  2. Test Procedures
    The test consists of four parts:
    1. Ordinary lubricating oil test
    2. Lubricating oil with anti-wear additive test
    3. Ordinary lubricating oil test (again)
    4. Repair test
    Before each test, the grinding wheel must be cleaned. Otherwise, the test results will be inaccurate. The standard for cleaning the grinding wheel is normal operation without noise.
  3. Weight and Wear Indicators
    The weight of the counterweight represents the pressure at the contact point, while the size of the ball track indicates the wear resistance of the lubricant or anti-wear additive. Changes in the counterweight correspond to changes in pressure at the contact point.
  4. Placing the Counterweight
    Gently place the counterweight on the motor and hold it for about 3-5 seconds until the motor runs normally. If the motor stops after adding the counterweight due to loss of lubrication with ordinary lubricating oil, immediately turn off the power to prevent motor burnout.
  5. Checking Weight and Wear
    Inspect the weight (indicating lubricity) and observe the wear condition of the friction plate (indicating wear resistance).
  6. Testing Lubrication with Water
    After testing the oil, add a certain amount of water to the oil tank. If the machine can still operate, it indicates that the anti-wear emulsified oil has lubricating properties, which ordinary lubricating oil cannot achieve.
  7. Purpose of the Test
    This test is designed to demonstrate the lubricity and wear resistance of different lubricating oils under the same conditions.

Precautions

  1. Positioning and Cleaning
    For each experiment, rotate the steel ball to a new position and clean the oil tank and grinding wheel. Wipe clean with tissue paper. Failure to do so will result in inaccurate test results.
  2. Power Off at Limits
    When the grinding wheel and test steel ball reach their limits, immediately turn off the power switch to prevent motor damage due to excessive load.
  3. Loading Rate
    Conduct the test at a constant rate, typically increasing the load weight every 10 seconds. The speed should neither be too fast nor too slow, as this will affect the repeatability of the test.
  4. Pre-Soaking the Grinding Wheel
    Before loading the counterweight, let the grinding wheel run idle in the test oil for a while to allow the oil film to form fully.
  5. Protecting Machine Lifespan
    This machine is primarily used for anti-wear and extreme pressure comparison tests of lubricating oils. To protect the machine's lifespan, avoid overloading or conducting destructive tests for extended periods.
  6. Temperature Monitoring
    All models can accommodate a thermometer probe to observe the increase in oil temperature.
  7. Avoid Disassembly
    This device is a precision electronic instrument. Do not disassemble it arbitrarily, as this may affect normal use.

Important Note

  • Voltage: This machine operates on 220V. Ensure the power supply matches this requirement to avoid damage.
