Considerations in Vibration Isolator Selection

Nowadays, the development of vibrating screen has reached the stage of noise reduction. Noise reduction machinery produces less noise and more comfortable working environment. During the selection of vibration isolator for a vibrating screen, there are few elements needed to be considered. Let Henan Pingyuan Mining Machinery share some information regarding to considerations in vibration isolator selection with you.

 

1.    Machine location

- As far away from sensitive area as possible

- On a rigid foundation as possible (on grade is best)

 

2.    Proper sizing of isolator units

- Correct stiffness (specified by the static deflection, more flexible is generally better)

- Sufficient travel to prevent bottoming out during shock loads, or during system startup and shutdown

 

3.    Location of isolators

- Isolators should be equally loaded, and the machine should be level

 

4.    Stability

- Sideways motion should be restrained with snubbers. The diameter of the spring should also be greater than its compressed height. Isolator springs should occupy a wide footprint for stability.

 

5.    Adjustment

- Springs should have free travel, should not be fully compressed nor hitting a mechanical stop.

 

6.    Eliminate vibration short circuits

- Any mechanical connection between machine and foundation which bypasses the isolators, such as pipes, conduits, binding springs, poorly adjusted snubbers or mechanical stops.

 

7.    Fail safe operation

- Should a spring break or become deflated, you must have mechanical supports on which the machine can rest without tipping.
