Basics of Technical Seals: How to Protect Your Equipment from Environmental Impact

Read and discover how the right technical seals can protect your devices and extend their lifespan.

The role of seals in protecting devices

The fundamental aspect of ensuring reliable protection for technological devices and machines is understanding the role of technical seals. These elements are designed to protect the internal components of devices from the harmful effects of external factors, such as moisture, dust, or drastic temperature changes. The role of technical seals is to guarantee full functionality and high efficiency of mechanical or electronic systems by providing a safe and stable working environment. They serve as the first line of defense in protecting devices, exhibiting several key functions:

• Preventing the ingress of liquids or small particles into the interior of devices, which could lead to corrosion, wear, or mechanical damage.
• Maintaining stable working conditions by protecting against extreme temperatures and pressure changes.
• Reducing the risk of failures and unplanned downtimes by improving the safety and reliability of equipment.

When considering the role of technical seals, one cannot forget that they have a direct impact on extending the lifespan of your equipment, and thus on reducing the costs associated with their operation and maintenance.

Types of technical seals

The broad spectrum of technical seals includes various types, including circular cross-section sealing rings and rubber and silicone cords with a circular cross-section. . Circular cross-section sealing rings play a key role, especially in mechanical devices, providing excellent sealing through a tight fit to the parts. They are designed to minimize leaks, protecting the internal components of the device. Shaft seals, also known as oil seals, are a specialized type of seal that ensure tightness at points where the shaft passes through the device housing. Oil seals are essential for protecting mechanisms from contamination and loss of lubricants.

On the other hand, rubber and silicone cords with a circular cross-section are extremely versatile. Due to their flexibility and resistance to various weather conditions, they can be used in different devices and environments. Whether you need a gasket resistant to high temperatures or a gasket with high compressive strength, rubber and silicone cords with a circular cross-section are an excellent choice. Remember that the correct selection of seals is crucial for the functioning of your devices and can significantly extend their lifespan.

Selection of seals for rotating shafts

When choosing sealing rings for rotating shafts, Several key aspects must be taken into account. The first and most important is to ensure effective protection of your devices by minimizing the risk of failure. Proper sealing of the rollers can protect the internal components of the device from the influence of external factors such as moisture, dust, or extreme temperatures.

Choosing sealing rings for rotating shafts, You should focus on:

• Durability - the rings should be resistant to wear, which translates to a long lifespan of the rotary shafts themselves.
• Flexibility - it is the key to ensuring an adequate fit for different types of rollers.
• Resistance to various conditions - the rings must be resistant to different types of external factors in order to effectively protect machines and equipment.

Sealing rings for rotating shafts They serve as a key component in the protection of mechanical devices. Therefore, the appropriate selection of these rings is essential to ensure the long-term efficiency and safety of your equipment.

The use of scraping and resistance rings

There are numerous types of technical seals available on the market, one of which is auxiliary resistance and scraping rings. These rings, also known as sealing rings, are indispensable in sealing systems, where they ensure the protection and safe operation of your devices. They work by maintaining optimal tightness between the elements that must remain isolated from external conditions.

Support rings and scraping rings are particularly useful in sealing rotating shafts, supporting functionality sealing rings for rotating shafts and improve the sealing efficiency. The backup rings protect the seals from exerting too much pressure on the components of the apparatus, while the wiper rings prevent unwanted particles or fluids from entering the inside. These two types of rings create a protective barrier that safeguards essential components of technological machines. Thanks to resistance and scraping rings, You can effectively extend the lifespan of your devices and increase their efficiency, which translates into savings in service and maintenance costs.

Environmental factors affecting seals

Environmental factors have a significant impact on the performance and durability of technical seals. Thermal loads, humidity, contact with chemicals, and the action of solid particles can considerably limit the effectiveness of seals and shorten their lifespan. The environment in which the seals operate presents a number of challenges that they must effectively overcome to ensure the continuity of your technological equipment's operation.

The pace of changing temperatures, high humidity, and extreme pressure differences – all of these factors affect the properties and parameters of technical seals. For example, strongly oscillating temperatures can impact the elasticity of seals, making them more susceptible to mechanical damage, which in turn leads to a shorter lifespan. Moisture and solid particles, on the other hand, can accelerate corrosion processes. This is just a part of the phenomena that seals have to deal with on a daily basis. Therefore, it is crucial that the individual components of seals are selected with consideration of the specific environment in which they are to operate. Choosing the right technical seals that take specific environmental factors into account is key to ensuring their long-lasting and trouble-free operation.

Installation and maintenance of seals

Both proper installation and regular maintenance are crucial for maintaining the reliability of technical seals. Strict adherence to installation instructions and maintenance principles guarantees the long-lasting and effective operation of the seals. During the installation itself, it is important to follow the technical specifications provided by the manufacturer. Improper installation can lead to premature damage to the seals, which in turn can result in unplanned downtime of your equipment.

On the other hand, regular maintenance is essential for preserving the functionality of seals over a longer period. We replace seals as soon as we notice any signs of wear. In addition, we regularly check and maintain the proper working conditions, such as monitoring temperatures and operating pressures. Proper storage and protection of technical seals before use are also important. These practices will help ensure effective protection of your equipment and extend the lifespan of the seals.

Modern materials in technical seals

Modern materials such as acrylic rubber, fluorocarbon rubber, nitrile rubber, polyurethane, Teflon, and silicone rubber offer exceptional properties that are effective in the most demanding applications. Acrylic rubber is valued for its excellent resistance to UV rays and higher temperatures, making it ideal for outdoor use. Fluorocarbon rubber, known for its high resistance to chemicals and temperature, is an excellent choice for the chemical and automotive industries, where conditions are particularly harsh.

Nitrile rubber, on the other hand, is preferred in applications where resistance to oils and fuels is important. Its durability and flexibility make it widely used in the automotive industry and in the production of various types of hoses. Polyurethane, in turn, offers exceptional mechanical strength and is resistant to abrasion, making it perfect for seals in devices that are subjected to intense friction or heavy loads. Teflon, known as PTFE, is indispensable where minimal adhesion and the lowest possible friction are needed, as well as resistance to a very wide range of temperatures and chemicals. Silicone rubber stands out for its excellent flexibility at low temperatures and thermal stability, making it ideal for applications in both very low and high temperatures. Its biocompatibility and lack of reactivity also make it a choice in the food and medical industries.
