Current fluctuation
Thread Content
There is a reduction mixer that uses forced lubrication; its speed is 0.15 revolutions per minute. An oil pump draws oil from below and circulates it upwards to ensure forced lubrication. It operates outdoors, and recently it was observed that fluctuations in current are correlated with changes in temperature, ranging from 5.8 to 6.3. I wonder, experts, whether it’s because the temperature rises, causing the oil’s viscosity to decrease and the lubrication film in the reducer to thin out, which in turn leads to higher current levels during operation? Will this happen?
Since it is forced lubrication, what is the temperature of the lubricating oil, and does this change? As the ambient temperature rises, the motor’s heat dissipation capacity decreases; to produce the same amount of power, the load on the motor increases. Consider whether this could be the reason.
