Coil springs are vital to the optimal function of compressor valves. Materials utilized in the construction of the springs should be carefully selected to withstand the specific wear that will occur depending on the type of machinery used and the surrounding environment. Consider the following four principles when purchasing coil springs to achieve a better outcome.
Form
Begin with the basics and find out the size, strength, and structure of spring that you will need for your equipment. Ask manufacturing experts to share their input on the type of spring that will work best. There are diverse designs for spring mechanics to handle stresses across one or more normal planes, and you will need to choose a model that provides the correct tolerance. You may want to look into flat wire springs. These are more difficult to construct but provide several benefits including better shockabsorption, wider impact distribution, and tighter concentration of energy for use in smaller spaces.
Temperature
You will need to calculate the temperature at which your springs will operate. Even small deviations from room temperature can influence the function of materials used in spring construction. Certain types of materials including MP35N and Nimonic 90 can perform well at temperatures as high as 1020 degrees Fahrenheit.
Location
Different climates and geographical areas present diverse challenges to part maintenance. When selecting springs, research the corrosive elements you should be aware of and the materials that will stand the test of time in your location. Some corrosive elements to consider are:
- Humidity
- Sea water
- Nitric acid
- Sulfur dioxide
- Sulfuric acid
- Hydrogen sulfide
There are additional factors relating to premature corrosion, so be sure to research the environment thoroughly before choosing your material.
The Test Run
Once you have conducted the proper investigation and made choices on the features of your springs, you should be sure that calculations and simulations have been implemented and verified through prototypes of the springs you are considering. No amount of theory can compete with practical application.
Choose Wisely
Do not make the mistake of choosing any basic spring to use in your machinery. Selecting the correct coil springs will provide you with better performance and reduce your overall costs.
