The spring rate/stiffness calculation has been covered in the previous blog article. Springs are not designed to be stretched or compressed beyond their elastic limits, i.e. springs obey Hooke’s law, F = k x d. F = force applied on the springk = spring rate
Wear can be caused by the relative motion between two surfaces that are in close contact, causing deformation or removal of the material; this is known as mechanical wear. Wear can also be caused by other sources such as harsh or reactive chemicals, or cavitation.
Industrial fans are mostly used to transfer fluid, typically gas or air in many applications. Obtaining high performance fans has been a challenge due to vibration-related issues and harsh environments: temperature, fluid, and humidity. Vibration has been known to reduce the lifetime of fans, decrease
Infrared thermography, or thermal imaging, can be used as a means of detecting radiated energy/heat from objects. Thermography can be a convenient method for detecting excessive heat build-up, which may be attributed to conditions of increased mechanical wear, electrical faults, steam leaks, to name a
Belt drives are commonly used to transmit power. They are cheap and easy to maintain. However they are often a source of vibration due to misalignment, belt wear, and belt resonance. Belt misalignment can be identified from frequency spectrum, 1X vibration in both the radial
Machinery in industrial environments typically generate a lot of noise. Other than being very loud, these noise emissions can sometimes provide clues to the condition of a particular machine. Measuring ultrasonics can be useful in detecting: • Steam and air leaks • Lubrication issues •
