Reasons for high vibration in Roots blowers
Thread Content
I need help. As stated in the question, the horizontal vibration is 10 and the vertical vibration is 9; the horizontal vibration speed is 9 mm/s. Is this level of vibration considered high? The temperature isn’t high, but the noise level is extremely loud; it’s scary to listen to. When touching the outlet pipelines and the fan mounts, a noticeable vibration can be felt. I hope someone experienced can help figure out what the cause is – is this normal behavior?
Why is the entire base raised? A manufacturer’s base together with shock absorbers will suffice
Vibration is very difficult to keep under control; the Roots blower we purchased has the same problem – once it starts running, it vibrates heavily, just like an airplane. I remember that the blower itself has shock-absorbing springs
The vibration linear velocity is 9 mm/s, which should be fine. I wonder what medium is being transported? If it’s air, it can still be used. If it is a flammable or explosive medium, it’s dangerous! L, contact the manufacturer as soon as possible!
We encountered this problem as well; upon inspection, it was found that the liquid level in the tank had risen, resulting in pressure buildup at the pump outlet and causing vibration.
Suspension generally results in greater vibration than when there is no suspension
I don’t know either why it’s set in a fictional world; that’s just how it is when I come here
If I’m not mistaken, the national standard specifies that a vibration level within 11.2 is acceptable. There are many reasons for high vibration levels; you can start by checking the condition of the bearing lubrication to see if it’s time to change the oil
In the case of vibration, it is necessary to determine whether the vibration level has always been high or if it has increased suddenly recently; the approach to dealing with this issue differs in each case. If the vibration level increases suddenly, immediate maintenance is required. If it has been high throughout, it is possible to monitor the trend of vibration changes, and if there is no significant increase, operation can be continued under monitoring. For rotary vane blowers, is it the large vibration in their structure or rather the impact of installation and clearance issues? Should a major overhaul and inspection be considered?
Are all the parts for major overhauls purchased from the manufacturers?
