Problems with gas blowers
Thread Content
In our plant, the pressure behind the gas blower suddenly rose to 24 kPa due to the shutdown of the Roots blower; it dropped to 20 kPa after 5 minutes. However, in the end, friction between the impeller of the gas blower and the front bearing caused a failure of the blower. During this period, the main and auxiliary oil pumps were switched over, and the temperature of the thrust bearings rose to 99°C. We would like to ask the experts: was the blower failure caused by the high pressure or by the high temperature of the bearings?
The thrust pad temperature has risen to 99°C, raising the likelihood of an interlock-induced shutdown
