What is vibration isolation mounting?
Vibration isolation mounts protect machinery by reducing the amplitude and frequency of vibrational waves. Applications such as large motors and industrial machines generate powerful vibrations and excessive noise when active. Those vibrations cause damage to the equipment and create unsafe working conditions.
How do I choose anti-vibration mounts?
How to choose the right anti-vibration mount?
- Know the total weight of the machine.
- Check the weight of the anti-vibration mounts you need.
- Measure the running speed of the machine.
- Identify the static deflection of the anti-vibration mount.
- Material and shape.
- Time to choose your anti-vibration mount.
How does an anti-vibration mount work?
When your machine is being used, the mounts absorb and dampen vibration, significantly minimising the impact of vibration, such as noise. Vibration mount standoffs, also called stud mounts, are often made of rubber and steel, and prevent excessive vibration. These act as a cushion and are sandwiched between two parts.
What are vibration isolators used for?
A mechanical vibration isolator is a flexible support used to decouple a material from forced vibration. Springs are commonly used as isolators to minimize the transmitted vibrational force. These springs may involve steel coil, rubber, pneumatic, fluid damping, or combination of one or more.
What material is best for vibration damping?
Rubber
Rubber is an ideal material for vibration damping applications. It absorbs energy before re-releasing it into the environment as heat, which helps quickly isolate vibration.
What are spring mounts?
Spring Mounts are mounts that are combined with one or more springs and placed under the equipment. The springs create an air gap that allows for free oscillation of the equipment with minimal transfer of energy into the structure.
Why is rubber used for anti vibration mounts?
Rubber is used as vibration absorbers, because rubber has a relatively high shear modulus compared to other materials. That means when a rubber material is shear stressed, i.e. stressed parallel to its cross-section, rubber can be stressed more before it becomes permanently deformed.
How do I choose an isolator rating?
The Isolators shall be suitable to carry the rated current continuously and full short circuit current of 63/40/31.5/25 KA for 400/220/132/33 KV respectively for 3 second at site condition without any appreciable rise in temperature. These shall also be suitable for operation at 110% rated (normal) voltage.
