Working principle: .Leverage principle.
Scope of application: various brands, specifications, models, engine oils and other oil products
Motor power: 230W/280W
Display mode: pointer table display/digital display
Voltage/frequency: 220V/50HZ
Product color: blue
Accessories list: One host. 12 weights, 50 steel balls and 2 oil rings. 2 oil pans, a set of large and small levers, and a power line manual
1, Before each experiment, the friction wheel must be polished and polished with ordinary oil, otherwise it will affect the correct effect of the experiment.
2, To do four tests, 1, ordinary oil test, 2, adding anti-wear agent oil test, 3, oil test, 4, repair test. Before each test must be grinding wheel clean, otherwise the test results are not accurate, grinding wheel clean standard is normal operation without noise.
3, The weight of the weight on behalf of the pressure on the contact point, the size of the ball marks on behalf of the wear resistance of lubricants or anti-wear agent. Changes in the amount of weight equivalent to change the size of the pressure on the contact point.
4, Until the normal operation of the motor can be placed on the weight gently, the time interval of about 3-5 seconds. Added to the weight of ordinary lubricants to lose lubrication is locked, the engine stops rotating so far. At this moment, turn off the power immediately to prevent the motor from burning out.
5, Check the amount of weight (lubricity), observe friction pad wear (abrasion resistance).
6, Done after the oil test can add a certain amount of water to the fuel tank, and then found the machine still functioning, showing the lubrication effect of anti-wear emulsified oil. This is ordinary lubricants can not.
7, This just shows the lubricity and abrasion resistance of different lubricants under the same conditions.
Precautions
1. Each 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.
2. 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.
4. 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.
5. 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.
6. Each model can be inserted into the thermometer probe to observe the oil temperature rise.
7. Equipment Department of precision electronic equipment, can not be arbitrarily removed, so as not to affect the normal use.
Note: This machine is 220v! If you need 110v, please contact customer service!
