In machinery, vibration can be exemplified by the oscillation or motions of mechanical components. Some of the most common machines we see in our day-to-day lives are pumps, generators, engines, and so on. All of these produce vibration. In any industrial environment, mechanical vibrations are common and expected. It’s a crucial part of the machinery, in fact. Though too much of it could mean trouble, vibrations are unavoidable when using heavy machinery. But these vibrations can sometimes go against industry standards or permeate dissatisfaction among the clientele.
What causes these vibrations?
It can be a difficult question to answer, but it should not be ignored. If you want to prevent mechanical vibration, then knowing what causes them is essential. Machines produce vibration essentially from two sources: the motor and the inner gears. Then again they can come to one place or many places at once. Vibrations are most commonly produced when a solid body moves from a balanced position. Tests performed on the gears can help us determine the accuracy of the manufacturing dimensions.
Over time the mechanical parts can be worn out and deformed. Because of that the over machine can become deteriorated. The heat generated from machines can also cause this problem. Thermal expansion of gears can cause an imbalance within the mechanical system that might start a chain reaction. It’s sometimes overwhelming how these little things can build up to cause such an unexpected disaster. But if you can figure out the early signs then preventing this will be a lot easier.
What should I do to reduce vibrations in machines?
There are numerous ways to reduce vibration in any mechanical system. Once you have fully understood the source of these vibrations, following these methods will be immensely easier. Here are some of the common equipment and methods used to reduce mechanical vibration:
- Spring absorbers are a kind of equipment used in suspended systems. They can effectively absorb vibrations and noise from machinery. Their application can be noticed in Ducts & Pipes, Fan coil units, and so on. Usually, these hangers are made of very durable steel springs and brackets, and rubber cups. They are designed to withstand heavy impacts and are rustproof.
- Ribbed pads, waffle pads, rubber pads, etc. are different types of Anti-vibration pads. Like spring pads they are also used in fans and fan coil units. Anti-vibration pads are also applied in air handling units and generator pumps. They are very reliable because of their high durability and resistance to water, oil, ozone, etc., because the body of these isolation pads is made of high-grade Neoprene.
- Spring isolators are chiefly used un rotating machines to absorb noise and vibration. They are also known as spring mounts. Their application can be noticed in air handling units, pumps, fans, and so on. Spring isolators are available in varying deflection rate and load capacity.
- Wire rope isolators are used in motor generators, HVAC equipment, aircraft, compressors, and so on. They are typically used to suppress vibration and shock in machines. They are constructed with wire rope cables and aluminum alloy retaining bars. The culmination of these high-grade materials is what makes wire rope isolators so effective.
Should I worry about mechanical vibrations?
Vibrations are pretty much unavoidable when you are operating some kind of heavy machinery. Usually, machines are designed to produce the least amount of vibration as that could subtly waste potential energy and fuel. So excessive vibration can actually be one of the first signs of trouble. The inner gears or motors might not be functioning properly, or the mechanical parts could be damaged.
If left untended to, such sort of misalignment might decrease productivity greatly and can even make the workplace hazardous. Vibrations may not sound very dangerous, but they can cause great harm to the human body. When a human body comes into contact with certain levels of vibrations, it can cause serious health risks. The repercussions could be a permanent wound. So it would be unwise to neglect sudden unexpected vibrations and noises from machinery.
Some additional tips
Some common issues cause excess vibration inside the machinery. Here are a few more things you should look into as well:
- Try reducing the transmission errors
- The gear operations should be properly functional
- Use gears that ensure less noise generation without sacrificing proper contact
- Try to know as much as you can about the machine at hand and the industry standards and schematics
One can only expect vibrations from heavy machinery. But like we have mentioned before, it can greatly cost you if you neglect its importance. It is not just vibrations. Heavy machinery themselves are quite hazardous to the inexperienced. Hopefully, after reading this, you have had an appropriate overview of this matter. Check thiscompact website for more details.
