TMK lubricating oil anti-wear testing machine is specially customized for lubricating oil and its additive enterprises Quickly and intuitively mirror the anti-wear and anti-friction performance of lubricating oil This lubricating oil anti-wear trying out machine adopts an integrated design to effectively lower vibration and noise during paintings Its main operating elements are composed of a friction ring that rotates with the key shaft and a hard and fast friction column pressed on the friction ring Under conditions, sliding friction happens between the friction ring and the friction column
The lubricating oil anti-wear testing mechanical device pressurizes the friction pair via an afterburner system composed of weights and levers, so that extremely high pressure is generated at the contact level During the rotation of the friction ring, the wear and tear of the friction column (experimental steel ball) is sped up to monitor and examine apparatus for assessing the load-carrying skill of lubricants Under this particular lubricating condition, 1 minute of simulation examine is equivalent to the wear quantity of regular operation of overall parts for 1 yr High-grade lubricating oil wears less under an identical load, and the spindle pace would not drop or drops little or no Because the lubricating oil anti-wear testing machine can quickly and concisely reflect the anti-wear and anti-friction performance of lubricating oil, it is often used in the production, examine and advancement and promotion of lubricating oil or anti-wear agent with greater anti-wear performance
Before using this lubricating oil anti-wear checking out machine, it'll be famous that the home mains voltage is AC 220 volts, and ±5% is appropriate, the electric method must be wisely grounded, and the operator must have logic of mechanical and electrical security This collection of lubricating oil anti-wear testing machines have diversified models and costs consistent with diversified configurations
Instructions for use of DY-TMK anti-wear trying out mechanical device
1 Before each experiment, the friction wheel should be polished with whetstone dipped in traditional oil, otherwise the proper effect of the experiment might be affected
2, to do 4 tests,
1 The examine of normal oil,
2 The examine of oil with anti-wear agent added,
three No oil test,
4 Repair examine
The grinding wheel must be polished earlier than every single test, otherwise the check results might be inaccurate The usual for grinding the grinding wheel is ordinary operation with out noise
3 The weight of the load represents the pressure on the contact point, and the size of the wear and tear scar of the metallic ball represents the anti-wear estate of the lubricating oil or anti-wear agent Changing the number of weights is akin to replacing the quantity of stress on the contacts
four The weight can be gently positioned after the motor is running normally, and the time period is about 3-5 seconds Adding to the number of weights makes normal lubricating oil lose its lubricity and lock up till the engine stops rotating At this time, the ability needs to be turned off directly to forestall the motor from burning
five Check the number of weights (lubricity) and word the damage marks (wear resistance) of the friction block
6 After the oil-free test, a certain amount of water can be added to the oil box, after which it is came upon that the machine remains to be running, exhibiting the lubricating effect of the emulsified oil containing anti-wear agent This is something that normal lubricating oil can&;t do
7 This is just to reveal the lubricity and anti-wear homes of different lubricating oils beneath the same situations
It is precisely forbidden to begin the anti-wear trying out machine under load!
Precautions
1 Every time you do an experiment, it's best to turn the steel ball to a new position, clean the oil box, grind the grinding wheel, and wipe it with toilet paper, in any other case the experimental results might be erroneous
2 Turn off the flexibility switch when the grinding wheel and the experimental metallic ball are locked to avoid damage to the motor thanks to immoderate load
3 When loading weights, the rate should be uniform, generally including one piece each 10 seconds It can&;t be fast or slow, otherwise the test reproducibility is not good
four Before loading the weight, let the grinding wheel run with out load in the oil to be examined for a while, so that the oil movie could be completely shaped
5 This mechanical device is principally used for the comparability experiment of the anti-wear and severe strain houses of oil merchandise In order to guard the provider lifetime of the machine, please do not perform overload and detrimental experiments for decades
6 All items would be inserted into the thermometer probe to watch the oil temperature upward push
7 The kit is a precision electronic instrument and cannot be disassembled arbitrarily, so as to not impact the normal use
DY-TMK type lubricating oil anti-wear checking out mechanical device supplementary expansion operate
There are three experimental purposes to check the performance of oil products:
1 Test the anti-wear functionality of the oil (record the scale of the wear and tear scar of the experimental metal ball, the motor recent and the oil temperature change)
(1): When the test oil is typical oil, place weights, the normal oil movie on the grinding wheel breaks, the current increases, and the grinding wheel makes a harsh noise At this time, the grinding wheel and the experimental metallic ball are quickly locked (turn off the flexibility immediately) Remove the experimental metal ball on the short lever to see the wear and tear marks, the marks are huge (3×6mm2), and the scratches are deep
(2): When the verify oil is high-grade oil with anti-wear agent added, put the weights one by means of one, however the latest would not increase, the grinding wheel and the experimental metal ball are usually not locked, the noise is terribly small to no, flip off the power, and watch the damage marks , the hint is terribly small (1 × 2) The put on scar comparison examine of different manufacturers of comparable oil could be carried out
2 Test the extreme strain performance of the oil (record the utmost variety of weights placed during the experiment)
When the grinding wheel is rubbed with the experimental steel ball, within a certain period of time (for example, 3 minutes), the maximum number of weights carried by the oil is the mirrored image of maximum pressure When a small amount of weights are put on typical oil, the oil movie may be broken, and the grinding wheel and the steel ball might be locked The high-grade oil with anti-wear extreme stress agent can add up to 15-20 weights or maybe extra weights, and the oil movie still works nicely
Note: Grease (butter) can be tested by means of picking wooden chips into the distance between the metallic ball and the grinding wheel
three The oil-free operating check is to test the oil-free extreme pressure and anti-wear functionality of the oil
Remove the oil box, don't grind the grinding wheel, the fast rod steel balls stay in place, upload weights one through one, and after a undeniable era of time, turn off the ability supply, the damage marks on the experimental metal balls haven't increased, indicating that an oil film has been formed at the metal surface
There are two generally used experimental applications for the touch components between the grinding wheel and the experimental metal ball:
1 Point touch experiment function;
The experimental steel ball is positioned in parallel within the brief lever notch to make vertical contact with the grinding wheel, and the verify end result shows that the wear and tear scar is an approximate elliptical level
2 Line contact experiment operate
The experimental steel ball is positioned vertically in the quick lever notch to make parallel touch with the grinding wheel, and the check outcome shows that the wear and tear scar is in the form of a line This experimental formula has a enormous friction surface, and the oil temperature changes for sure At this time, insert the probe of the thermometer into the oil box and immerse it within the experimental oil, switch on the power, and the temperature rise performance of the oil would be considered maximum intuitively Generally, the oil with solid anti-wear performance adjustments slowly and the oil temperature is low Otherwise, the oil temperature could be high
