How to reduce bearing temperature in Henan Roots blowers
Release time:
2020-11-25
The external environment can also affect the bearing temperature of the Roots blower. In winter, when the room temperature is low, the blower operates well. When the room temperature is 5℃, the temperature of the front bearing of the blower is about 80℃. In summer, when the room temperature exceeds 30℃, as the room temperature rises, the front bearing of the Roots blower exceeds the set trip temperature. To avoid tripping, the unit personnel increased the machine.

In summer, when the room temperature exceeds 30°C, as the room temperature rises, the front bearing of the Roots blower exceeds the set trip temperature. To avoid tripping, the unit personnel increased water spray cooling inside the casing as an emergency measure, but the sanitary conditions during operation are poor, so it is now recommended to adopt some simple and quick methods.
As a forced air supply device, the Roots blower forces air during the air supply process, forcibly compressing the air and releasing a certain amount of heat, which raises the temperature of the machine body and also increases the air temperature. This is the main reason for the rise in the outlet temperature of the Roots blower, and excessively high temperatures may also be due to other reasons, such as blower failure, mechanical friction, etc.
High temperatures can affect bearings, seals, lubricating oil, etc., and will directly impact the normal operation of the blower. The harm of high temperatures to the blower is quite significant.
1. A simple and feasible method is to add a sunshade outside the fan, which is one of the direct cooling methods.
2. If the temperature of axial flow fans, wear-resistant fans, and other fans rises too high, it is likely due to not closing the inlet and outlet duct gates during operation. Countermeasure: Just close the gates of the inlet and outlet ducts.
3. Additionally, due to severe vibrations of the casing, misalignment of the shaft and rolling bearings, eccentricity of the front and rear bearings, damage to the rolling bearings of the blower, or bending of the shaft, all can affect the bearing temperature of the blower. Solution: Timely lubrication to reduce the friction coefficient.
4. If the motor belt is too loose, it is important to replace the motor belt in a timely manner and adjust the pulley to ensure even force.
Although it is now winter in the northern regions, it is still important to pay attention to the operating temperature of the blower equipment. If there are any other questions, feel free to consult us!
