When using this product, the starting current of the equipment was reduced from 590A to 550A, and it was found that the vibration of the equipment was significantly reduced. The oil in the tooth surface was sufficient through the observation hole, and there was no oil leakage. In February 2006, due to non-equipment problems, we checked the gears in detail. Observe that the oil film on the tooth surface is well formed, the original wear is not aggravated, and the original scratched silk line is obviously atrophied, leaving only the silk marks, no longer picking up the hand, and the pitting pit is lubricated by the solid in the HF-open gear extreme pressure lubricating oil. The material becomes smaller and smaller. After the high temperature, high load, high water drenching and dusty equipment in summer, the operation was still good, which proved that the selection of this product has significantly improved the lubrication of the equipment.
In order to further prove the lubrication performance of this new open gear lubrication material, we applied it again in the 5000t/d production line in October 2006. The original oil is a special lubricant for a foreign brand. The typical technical parameters are as follows:

density                             20℃g/cm3 0.92

Kinematic viscosity                      100℃mm2/s600

Viscosity index                                        120

Four ball test welding load N                       8000

Occlusal load rating ﹥12

range of working temperature                             15-120

Flash point opening °C ﹥200

Pour point °C ﹤10

Before the oil change, we observed the tooth surface, the tooth surface lubrication was basically good, but the oil leakage and vibration were slightly larger. We tested the vibration amplitude of the pinion housing and the results are as follows:

After switching to the HF-open gear extreme pressure lubricant, we also tested the vibration amplitude of the pinion shaft ride. The results are as follows:

From October 2006 to the end of the year, the maintenance equipment has been operating normally, without serious oil leakage. We wiped off the tooth surface oil, and observed that the oil film is obviously thickened and adsorbed with a layer of gray solid lubricating material, and the gear material is obviously not bright and the size is small. There are no abnormalities in the gears. The successful application of HF-open gear extreme pressure lubricant on the rotary kiln open gear has prompted us to achieve satisfactory results in the ball mill, and its price is only a fraction of that of imported products.
Through the application of this product, it shows many advantages of the product: good adhesion performance, strong self-sealing performance, temperature resistance, shear resistance, strong extreme pressure resistance, rapid, firm and long-lasting film formation, anti-watering, anti-water resistance Dust is not easily deteriorated.
