HZKM-3 110V Lubricating Oil Anti Wear Friction Tester

1. Machine use:

The HZKM-3 110V lubricating oil anti-wear friction tester is a specialized testing instrument designed to evaluate the lubricating and anti-wear properties of lubricating oils. In addition to assessing the base performance of the oil, the tester can also monitor the temperature changes that occur when the oil is mixed with anti-wear additives, providing valuable insights into the effects of additive-enhanced formulations.

2. Experimental conditions:

Under 110 V conditions, ordinary oil causes lock-up at 3–4 weights, while wear-resistant oil remains operational even at 12 weights.

3. Operation steps:

Step 1: Shaft Sleeve Preparation

Turn on the power and start the motor. Use a whetstone dipped in ordinary lubricating oil to thoroughly polish the shaft sleeve. When grinding, press the whetstone evenly with your thumb. After grinding, wipe the shaft sleeve and turn off the motor. The purpose of grinding is to eliminate the influence of the original oil film or nano-film on the experimental results.

Step 2: Test Setup

Fix the steel ball in the short lever groove of the testing machine. Add ordinary lubricating oil to the oil box, and install the oil box along with the long and short levers.

Step 3: Testing with Ordinary Lubricating Oil

Start the motor and let it run. Then, at regular intervals (approximately every 5 seconds), add weights one by one to the end of the long lever. Each weight for a passenger car applies 100 kg of pressure to the friction pair; for a truck (e.g., Steyr), each weight applies 2 tons of pressure. Record the number of weights and observe the ammeter pointer. An increase in the pointer indicates increased power consumption, which correlates with fuel consumption. Noise will gradually increase. Continue adding weights (approximately 3 to 4 pieces) until the grinding wheel stops and the machine locks up. Quickly turn off the power. Remove the weights, take off the short lever, and observe the wear scar depth, area, and roughness of the cylindrical grinding block.

Step 4: Test Force Calculation

The test force at the end of the long lever is calculated as: 0.6 (weight per piece) × N (number of weights) × 14 (lever ratio) = kilograms. To convert to kilogram-force: 0.6 × N × 14 × 9.8 N/m = kgf.

Step 5: Re-Grinding

Change the angle of the steel ball and reinstall the lever. Grind the shaft sleeve again, as the previous experiment has caused wear and it needs to be smoothed.

Step 6: Testing with Wear-Resistant Lubricating Oil

Add wear-resistant lubricating oil to the oil box.

Step 7: Comparison Test

Add weights one by one to the end of the long lever - 1 piece, 2 pieces, etc. With ordinary oil, the machine typically locks up after about 4 pieces. With our wear-resistant lubricant, the machine continues to operate normally beyond 4 pieces. Observe the ammeter needle; it moves only slightly. Current × voltage = power consumption. A minimal change in the ammeter pointer means electricity savings, which translates to fuel savings. Gradually add weights up to 12 pieces; the machine continues to operate normally.
