During operation of machines and other workshop equipment, a large number of vibrations and vibrations occur. In addition, during the operation of ventilation, as well as various engineering systems, shock waves of different strengths and frequencies may appear.
Shock waves have a negative impact on the functioning of units and machines located in a manufacturing plant. To eliminate this problem, special compensation elements are used that are able to dampen and minimize the vibrations that occur during the operation of various equipment.
Such compensation elements are special vibration supports that are capable of eliminating vibrations and also preventing their further spread throughout the territory of the production facility where the equipment is located. The editors of the YaNashla website have prepared for your attention, having previously read the reviews, advice, and recommendations of most users, a rating of the highest quality vibration supports and vibration cushions for equipment and machines as of 2022.
Description
Elements such as vibration supports can minimize and eliminate various shock waves that occur during the operation of machines, units or engineering systems (ventilation, liquid supply, etc.) located on the territory of an enterprise or production facility. Strong vibrations are dangerous because they can not only create extraneous noise that interferes with normal, full-fledged work, but also affect the quality and level of production. In addition, due to their constant exposure and shock waves, units, as well as machine components, quickly wear out, which leads to a decrease in their functionality and a decrease in service life.
Vibration refers to the resulting shock waves that have different frequency amplitudes. They appear as a result of the functioning of ventilation systems, various industrial units, and equipment. Vibration cushions can eliminate and minimize the occurrence and impact of vibrations on production equipment and power units.
For correct, reliable vibration protection of machine tools and other industrial mechanisms, you need to correctly select compensation elements (supports). It should be remembered that vibration mounts are not universal devices. Therefore, their selection must be carried out taking into account certain nuances, criteria, as well as the specifics of the operation of the equipment and power plant.
Criterias of choice
How to choose, what mistakes to avoid when choosing? Compensation supports, which are actively used during the operation of various industrial equipment and power units, are selected taking into account the following nuances:
- The type of vibrations that occur. When choosing vibration supports, you should determine the frequency and frequency of vibrations. After all, various types of vibrations occur on a variety of equipment, which must be taken into account when selecting vibration pads.
- Weight of equipment. When choosing compensation elements, it is imperative to take into account the mass of the power units on which they will be installed. Otherwise, a vibration cushion that does not correspond to the weight of the machine will not be able to effectively dampen or eliminate the resulting vibrations. It is worth noting that the vibration supports used must withstand the maximum weight of the machine (during downtime and during work, the weight of the equipment used changes).
- Movement. With different directions of oscillations and vibrations, vibration pads need to be mounted in different areas and structural elements of the machine. As a rule, compensation elements are mounted at the bottom of the machines. However, if necessary, they can be located in the upper or side parts of the power units.
- Operating environment. When selecting compensation materials, you should pay close attention to the conditions in which the equipment is operated (temperature changes, air humidity, the presence of various aggressive components, liquids).
It is not recommended to use supports that begin to collapse under the influence of low or high temperatures. In addition, it is preferable to use expansion joints whose metal components have a high level of resistance to corrosion and aggressive substances.
Advantages
Unfortunately, some enterprise managers do not attach special importance and due attention to the use of compensation materials in production to reduce force, as well as the level of vibrations that occur. Thanks to the use of vibration supports and vibration pads, you can:
- Significantly extend the service life of the equipment;
- Provide more favorable conditions for the operation of machine tools and power units;
- Reduce the amplitude and level of noise;
- Provide reliable protection of the floor covering from premature destruction and wear;
- They have good noise and vibration insulation properties;
- Significantly improve working conditions for personnel by reducing noise and vibration vibrations of production units and installations;
- Protect the elements and components of the equipment used from vibration effects (there is no need to frequently repair power plants).
In addition, thanks to the use of special supports, there is no urgent need for arranging a complex foundation for the subsequent installation of the power unit or machine. After all, installing a compensator is much easier, faster and cheaper than installing and pouring a foundation for the equipment to operate. It is worth noting that even a strong foundation is not always able to cope with the strong vibrations that occur during machine operation.
Kinds
What are there, and what are the criteria for choosing supports? Compensation materials come in several different types. They may differ from each other in both technical characteristics, functionality, and material of manufacture. Vibration isolation materials are:
- Rubber. The most common type of support. Their main advantage is accessibility and efficiency. After all, rubber is a common material that is easy to process. During the production of such expansion joints, rubber of natural as well as synthetic origin is used. It is worth noting that models of expansion joints that are made of rubber retain their properties and technical characteristics even when exposed to low temperatures. However, when exposed to high temperatures (+60 degrees Celsius or more), rubber begins to gradually deteriorate.
- Rubber-metal. Such expansion joints are additionally equipped with durable metal elements that allow them to withstand high loads. In addition, thanks to the use of such devices, you can independently adjust the height of the power plant (set the level of the machine, adjust the parameters of its location). Metal elements provide reliable protection for the rubber part of the expansion joints and protect it from destruction.
- Metal. They are used in cases where the weight of the machine does not allow the use of compensators made of rubber. As a rule, all-metal expansion joints are additionally equipped with a variety of shock-absorbing elements (springs or leaf springs). It is worth noting that this type of support, due to the fact that it is subject to deformation, is not suitable for all machines.
- Lead - asbestos. Rarely used in industrial facilities and production. They have little effectiveness. They are practically not used to protect machines from vibration.
It is worth noting that there are also supports made from materials such as felt or cork. They have a small ability to eliminate and dampen vibrations that occur during machine operation. Typically, they are used to adjust the height at which equipment should be located.
Reference! Vibration isolation can be active or, on the contrary, passive. Active is capable of extinguishing and also suppressing vibrations that arise during equipment operation. Passive vibration isolation is a special protection that protects equipment from the harmful effects of extraneous vibrations coming from the external environment.
Device and design of vibration supports
Compensators such as vibration supports have a simple, one might even say primitive, design. Their design includes:
- Protective cover;
- Rubber-metal element;
- Inner nut;
- Support screw;
- Washers (2 pieces);
- External nut.
Most different types of expansion joints have almost the same, similar design and installation method. The only difference between different models of supports may be such criteria as dimensions, diameter, as well as the length of the support screws, the maximum and minimum permissible load value. An ordinary warehouse without a heating or forced ventilation system is suitable for storing vibration supports.
Important! It is not recommended to transport supports without special protective packaging (in bulk). This is due to the fact that during transportation in bulk, the supports will be subject to mechanical stress, which can lead to damage to the protective paint coating.
The best vibration mounts and vibration cushions for machines and equipment for 2022
Vibration mounts and vibration cushions are durable vibration-absorbing compensation materials that are easy to install on lathes, milling machines and other power units. They perfectly eliminate and minimize the impact of vibrations and ensure safety when working on power plants. When choosing such supports, you should pay attention to the type and direction of vibrations occurring and the weight of the machine.
What to look for when choosing? What are the selection criteria? The best models of expansion joints are made of durable materials that do not collapse when exposed to aggressive environments or liquids. In addition, they are able to perfectly withstand changes in temperature and humidity inside the room or production workshop. Thanks to the use of supports, the so-called foundationless placement of machines in the workshop is possible. In addition, such compensators provide a higher level of mobility of machine power units.
Where can I buy? Vibration cushions and supports can be purchased in specialized stores or in online stores by placing an online order, having previously read the full catalog, which provides a description of the product, its functionality, properties, as well as technical characteristics (number of studs, equipment, type of fastening).
