How much does emulsification of lubricating oil reduce the transmission efficiency of WPA147-20 worm gear reducer

Emulsification of lubricating oil can indeed significantly reduce the transmission efficiency of WPA147-20 worm gear reducer, with a specific decrease usually between 1% and 3%. However, the actual impact still depends on the degree of emulsification and your maintenance situation.

1、 The impact mechanism of emulsification on efficiency

Decreased lubrication performance: After emulsification, the viscosity of the lubricating oil decreases, the oil film becomes thinner or even breaks, and the frictional resistance of gears and bearings will significantly increase. For example, the efficiency of the gearbox of a crusher in a certain mine decreased from 95% to 91% after emulsification.

Weakened heat dissipation ability: Emulsified liquid can block the oil circuit, affecting heat dissipation and causing the oil temperature to rise, further reducing the lubrication effect. The gearbox of a certain cement plant experienced a 2.3% decrease in efficiency after 6 years of operation due to scaling of the cooling water pipes.

2、 Actual reduction reference

Mild emulsification: The oil is slightly turbid, and the efficiency may decrease by about 1%.

Moderate emulsification: The oil is significantly turbid, and the efficiency may decrease by 1.5% to 2%.

Severe emulsification: The oil appears milky white, and the efficiency may decrease by 2% to 3% or even more.

3、 How to reduce the impact

Regular inspection: Clean the respirator filter every 3 months to prevent excessive internal pressure from squeezing the seals.

Environmental protection: Fluororubber (FKM) or silicone sealing rings should be preferred during the rainy season, and waterproof sealant should be applied to the sealing gaps.

Timely handling: Once emulsification is found, it is recommended to immediately change the oil and check the seal to avoid the problem from escalating.

If you find a significant decrease in efficiency, it is best to check the oil condition and sealing condition.
