Excessively high temperature in the bearing housing of the desulfurization slurry circulation pump
Thread Content
As the title suggests, the desulfurization circulation pump does not have a bearing housing cooling water system. The temperature is currently high; the outdoor temperature is 26°C, while the bearing temperature reaches 72°. Vibration levels are normal. The medium used for operation is plain water, with no slurry yet added. Seeking expert advice on a solution. I am extremely grateful
Has too much lubricant been added? Too much of it will cause the temperature to rise. Or: The bearing does not receive lubrication, resulting in dry friction within the bearing and an increase in its temperature. Or: bearing quality issues, insufficient bearing assembly precision.
Could it be due to an excessive oil level, or are there problems with the bearings?
Assembly should be fine. The vibration level is kept at ≤0.03 mm, and oil can also lubricate the bearings. It’s the high temperatures; last winter, the temperature rose to 80 degrees, and after some time, it’s now around 70 degrees as well
