NOTICE VOLTAGE 220Veach time to do an experiment to turn the ball in a new location, cleaning oil box, grinding wheel, And wipe clean with toilet paper, otherwise the experimental results are not accurate.Wheels and experimental ball reached the limit That is, turn off the power switch, so as to avoid excessive damage to the motor load. 3. To the average rate, typically every 10 seconds, plus a loading weight. Can not be fast or slow, or poor reproducibility of the test.Before loading the weight, the grinding wheel should be allowed to run without load for a while in the oil to be tested so that the oil film is fully formed.This machine is mainly used for oil anti-wear extreme pressure contrast experiment, in order to protect the life of the machine, Please do not overload, destructive experiment for a long time. Lubricant anti-wear testing machine, a total of 12 weights, A power cord, grinding stone 2, 50 steel balls
