Introduction
Most modern buildings today are equipped with mechanical devices such as air conditioning systems that generate vibration, shock and noise. The purpose of mechanical Anti-Vibration Mount is to reduce the vibration and noise transmission caused by mechanical equipment to industrial plant structures, residential apartments, and hospitals.
Determining the Transmission Percentage is done according to the Anti-Vibration application environment. In air conditioning we have a transfer rate of 1 to 10 percent. For sensitive areas with electronic equipment, transfer rates are between 2% and 3%, for hospitals 5% and for warehouses 10%.
Anti-Vibration mounts are usually categorized by the amount of static displacement. By specifying the amount of static displacement and the specificity of the load determined by the user according to their needs, one can obtain the coefficient of hardness as well as the natural frequency of the spring according to the formulas in the mechanical vibration references.
The amount of static permissible displacement is determined according to the location of the Anti-Vibration mounts application as well as its environment according to the ASHRAE standard as shown in the following table. According to this table, the user can easily determine the type of seismic used.
Advantages of Anti-Vibration mounts:
- Prevent vibration and vibration transmission to the building
- Reduce noise pollution
- Detailed engineering design and analysis
- Time saving installation and ease of execution
- Order-based production
- Reduce costs in system maintenance operations
- Significant durability and useful life
- Increase system performance and productivity
Spring Anti-Vibration
VESTA Dezh’s Spring Anti-Vibration shock absorbers are manufactured in two types of free and stopper (single and double stroke) which reduce noise, shock and vibration produced by mechanical and industrial equipment such as pumps, cool towers. Chillers, boilers and compressors are used. It is also recommended to absorb vibration loads with different frequencies and lateral loads to the structure.
Plastic Anti-Vibration
Plastic Anti-Vibration is produced in a double-bolt pulley, a bolt head, and a two-nut end.
