Since o-rings are small, they have excellent sealing and isolation functions, especially in mechanical equipment and systems. Without them, many functions cannot be used. Do you know? There are several classifications of them, with distinct characteristics, powerful functions, and a wide range of applications, which makes them sell well in the market.
Classification
Sealing rings are mainly divided into the following categories:
1. Rubber sealing rings: Due to their good elasticity and wear resistance, they are widely used in the sealing of various mechanical equipment. The materials of rubber sealing rings include butyl rubber, nitrile rubber, chloroprene rubber, silicone rubber, etc.
2. Polyurethane sealing rings: Polyurethane sealing rings have excellent physical, and mechanical properties and high heat resistance, and are widely used in the sealing of various high-voltage equipment.
3. Silicone rubber O-rings: Silicone rubber sealing rings have excellent high-temperature, low-temperature cold resistance, and aging resistance, and are widely used in high-tech fields such as electronics, aviation, and aerospace.
Features
1. Good elasticity: The sealing ring has excellent elasticity, which can ensure that it rebounds after deformation and ensures its normal sealing performance.
2. High-temperature resistance: The sealing ring can withstand high-temperature, low-temperature, and variable-temperature environments, and is not easy to deform and crack.
3. Corrosion resistance: The sealing ring has good acid and alkali resistance and chemical corrosion resistance, and is widely used in chemical, pharmaceutical, and other fields.
4. Good sealing: The internal pre-installed stress of the sealing ring is large, and its normal sealing performance can be guaranteed within a wide working pressure range.
5. Easy installation: The O-ring has a simple structure and is easy to install. It does not require special equipment and complex procedures and can be installed quickly.
Function
The sealing ring has the following functions:
1. Sealing function: The sealing ring can ensure that the liquid, gas and solid inside and outside the equipment do not leak to each other, and keep the equipment in normal working condition.
2. Dustproof function: The sealing ring can prevent foreign objects such as dust and sand from entering the equipment, ensuring the normal service life of the equipment.
3. Buffering effect: The sealing ring can play a buffering role. During the use of the equipment, it can reduce the impact and vibration of the equipment, thereby protecting the structure of the equipment from damage.
4. Conduction effect: O-rings can be used to conduct hydraulic energy and transmit hydraulic energy to mechanical parts.
Scope of application
Sealing rings are widely used in mechanical equipment, automobiles, chemicals, petroleum, electricity, aviation, aerospace, railways, and other fields. The specific scope of the application is as follows:
1. Mechanical equipment: When manufacturing mechanical equipment, sealing rings play a protective role in sealing performance and are widely used.
2. Automobiles: Sealing rings are used in automobile engines, transmissions, hydraulic cylinders, and other positions.
3. Chemicals and petroleum: Sealing rings have good corrosion resistance and high-temperature resistance in the chemical and petroleum fields and are widely used.
4. Electricity, aviation, aerospace, railways: These high-tech fields have very high requirements for sealing performance, and sealing rings can meet these high requirements.
O-rings are a mainstream type of seal on the market. They are rich in categories and have good characteristics. They play an important role in many occasions. However, when choosing them, you must be cautious and choose the right categories and specifications so that their value can be fully utilized.
