Some problems encountered in the use of Roots fan
Roots FansIn the use of the process of meeting the problem is inevitable, in order to let everyone better understand the Roots fan small make up to take you to understand.
The airtight cavity of the Roots fan is composed of the impeller, the casing, and the wall plate, and there is a certain standard gap in the design, and the airflow of the Roots fan will become smaller whenever this gap becomes larger. Whether it is between the impeller and the impeller, or between the impeller and the wall plate, or between the impeller and the casing, as long as the gap changes, there will be a smaller air volume, and the influence of the gap to change significantly, is the friction between the parts.
On the other hand, Roots fan conveying medium for clean air, but in ordinary use, often mixed with some dust particles and so on, these particles are sucked in, often stuck between the impeller and impeller, resulting in more serious wear.
The motor of Roots fan is also more expensive, and the motor is prone to burnout. In the case of overload, the chances of motor failure will be greatly increased, such as: bearing deformation, impeller friction, casing deformation and other conditions, will cause motor overload. Running the motor under overload will cause the motor to be burned, and it is difficult to repair the motor after it is burned.
Therefore, the maintenance of the motor mainly includes: checking the motor instrumentation every day to ensure that the motor works within the rated range, and using the belt rotation of the Roots blower to regularly check the belt condition.
Because the casing of the Roots fan is relatively large, it is easy to accumulate dust, so it is necessary to regularly clean the casing of the fan to remove dust.
Maintenance work of the casing mainly includes: pay attention to whether the link parts of the casing are tight. If the casing bolts are not tight, it is easy to cause deformation of the casing. The deformation of the casing will cause wear and tear of the impeller, and the wear and tear of the impeller will exacerbate the emergence of fan failures.
Fan bearings must be replaced in time if there is deformation. When replacing, we need to carry out dynamic balance test on the new bearing to ensure that its value is within the error range.
In addition, the bearing maintenance work mainly includes: check the bearing lubricant, whether there is the phenomenon of oil leakage, timely replacement of lubricant, to ensure that the lubricant does not deteriorate the situation occurs.
