What is the reason for the abnormal noise inside the head of the Roots blower
The abnormal noise generated inside the Roots blower head may be caused by various reasons. The following are some possible reasons and corresponding solutions:
1、 Mechanical component issues
1. Foreign objects inside the rotor: When the fan sucks in air, if particulate matter is sucked into the rotor, it may produce abnormal noise. At this point, the machine should be stopped for inspection and foreign objects should be removed.
2. Rotor misalignment and collision: If the two three bladed rotors of the Roots blower are misaligned, there will be collision noise between the impellers during operation. At this point, it is necessary to readjust the clearance of the rotor.
3. Bearing wear: Long term operation of bearings in the absence of oil can cause wear and increase the noise and abnormal noise of the fan. Oil should be replenished regularly and promptly. If the wear is severe, the bearings need to be replaced.
4. Gear problem: Gear wear or loose fixation may cause abnormal noise from the gear itself and damage the clearance and synchronization of impeller rotation. At this point, it is necessary to replace the gears and lubricate them properly.
2、 Installation and maintenance issues
1. Improper installation: Improper clearance between components during fan installation can cause additional friction and produce abnormal noise. In addition, loose anchor bolts or other fasteners may also cause abnormal noise. At this point, the clearance between the components should be readjusted, the anchor bolts should be tightened, and the base should be leveled.
2. Insufficient maintenance: After prolonged operation of the wind turbine, if necessary maintenance such as cleaning and lubrication is lacking, it may lead to increased wear and tear of mechanical components, resulting in abnormal noise. Therefore, regular maintenance and upkeep of the fan should be carried out.
3、 Operating condition issues
1. Export blockage: The inlet and outlet of the fan are not unobstructed, making it impossible to exhaust air. This can lead to a continuous increase in pressure, which in turn affects the increase in current and produces abnormal noise. At this point, the outlet should be blocked and kept unobstructed.
2. Unstable pressure: The noise level of the Roots blower increases with the pressure, and when there is a significant fluctuation in the pressure rise, the noise will also fluctuate and produce abnormal noise. At this point, it is necessary to check the pipeline and load, block them, and stabilize the pressure at the specified value.
3. Overload and Overheating: The fan is severely overloaded, causing overload and overheating, and even causing shaft deformation and abnormal noise due to friction between the impeller and the casing. At this point, the filter, outlet back pressure, system pressure, etc. should be checked, and the operating conditions should be adjusted to prevent overloading and overheating.
4、 Quality issues with the fan itself
If there are quality problems with the fan itself when it leaves the factory, such as rough parts production, improper clearance coordination, etc., it may also cause the fan to produce abnormal noise during operation. At this point, the manufacturer should be contacted for return to factory repair or replacement of relevant components.
In summary, the causes of abnormal noise inside the Roots blower head may involve multiple aspects such as mechanical components, installation and maintenance, operating conditions, and the quality of the blower itself. When investigating the cause of abnormal noise, the above factors should be comprehensively considered and corresponding solutions should be taken.
