Many of us while walking along the road might have heard a continuous vibration like noise near the transformers which seems like “hum.”. If you have not noticed then do it next time when you visit nearby a power transformer. Millions are exposed to sound levels that are likely to cause permanent hearing loss, even though many of them wear hearing protection devices. Even low-level vibrations and sound levels are harmful to both man and equipment. Therefore, time call for applying the most preferred way of engineering controls to reduce the noise of machinery or introduce a noise control element between machinery and workers.
Inside the power transformer, there is no rotating part as in motors and generators, but still, they produce the sound because whenever a ferromagnetic material comes in contact with varying magnetic field, it changes its dimensions which exactly occurs inside the transformer. During the operation of powered industrial equipment, vibrations will put stress on each tooling component in a machine. Vibrations and unwanted noise are the serious problems in any equipment, and they are the key ingredients to a noisy device.
Since this problem can’t be stopped so the question arises is how to reduce this kind of noise. In order to safeguard equipment and protect the hearing of your workers, vibration control devices can be utilized while power transformer manufacturing. Another most beneficial way is to use cushion padding and oil barriers during the manufacturing process of the transformer which can help in insulating the sound of vibration and hence it will reduce the noise appearing to the users. Another most important method is using proper innovation designs and materials like stiffeners while constructing the walls of the transformer tanks which will succeed in creating a noiseless transformer.
It is the acceptable and advantageous method of investment to correct equipment that is not level or machinery that does not have an equal distribution of its weight. Vibration pads under machinery reduce noise by simply absorbing and muffling vibrations by using the vibration mounts. Like the shocks in an automobile, vibration mounts have mechanical or pneumatic dampening effect that will cancel out vibrations by providing an equal and opposite force to the vibration. A mechanical vibration mount consists the high-tension spring through which pneumatic devices use either compressed air or liquid in order to absorb shock by either filling or emptying a cylinder support.
Other ways to achieve vibration control include the use of vibration mounts. Like the shocks in an automobile, vibration mounts have mechanical or pneumatic dampening effect that will cancel out vibrations by providing an equal and opposite force to the vibration. A mechanical vibration mount will typically consist of a high-tension spring, very similar to a car’s shock. Pneumatic devices use either compressed air or liquid in order to absorb shock by either filling or emptying a cylinder support.
With the many solutions available to level electrical equipment and dampen vibrations, there is no excuse to cause unneeded wear on machinery or risk workers’ hearing. The quality of your brand is what makes a business stand out from the competition. Take control of your equipment and start looking up the best options when it comes to quality, custom materials for the manufacturing that makes you unique amongst your competitors.
