Compressed Air Silencers
|
The noise created by the pneumatic valves is actually quite dangerous and it can cause permanent hearing loss. This can happen quicker than you might think. For example a simple half inch valve regulating a pneumatic cylinder making three strokes a minute result in a 92 dB[a] noise level. That's high! You can see how working in this atmosphere every day could lead to permanent damage to your ears. Adding an air silencer will do an excellent job of muffling the noise from the exhaust air no matter how many valves. In fact it is the easiest and most cost effective. The exhaust air has to be properly treated to make sure that the noise level is sufficiently reduced but also you need to reduce the oil mist and minimize all dangers to the user. A dump valve allows you to release large amounts of air at a high speed but the noise level will also be high which is why you need to add a silencer. A simple silencer is made from porous materials and is often enough to reduce the noise but if the simple solution isn't able to do the job you should look at a more heavy duty silencer. Silencers are rated for their noise level reduction capabilities as well as the back pressure which make it much easier to choose the equipment that will be adequate for the job. In fact unless you take the time to choose the correct silencer you will not reap the necessary benefits and your ears could still be at risk. The next most damaging problem is the pollution generated by the oil. The pneumatic lubrication systems result in a total loss system. The lubricant enters the system and it degrades as it is carried along grabbing dirt and impurities along the way. In a system that is properly lubricated and well maintained the amount of exhaust oil will be minimal and will be dispenses without bothering you. However when a system is not correctly maintained there can be a heavy amount of debris expelled which can be a health risk. That's why a dump valve should always be installed. Overall there are various elements that need your attention to ensure that users are kept safe but the need to reduce the noise is one of the most serious safety concerns.
