Rubber washer gasket is a common sealing element, widely used in various mechanical, engineering and industrial fields. In this article, we will introduce the structure, characteristics, material selection, scope of application and precautions for use of rubber gasket gaskets.
Structure and characteristics
Rubber gasket gaskets are usually made of rubber materials, which are soft, wear-resistant and corrosion-resistant. Their main structure is a circular or square ring shaped gasket, usually with holes or cut-outs on the inside to facilitate installation on bolts, screws or other fasteners. The characteristics of rubber washer gaskets are as follows:
Sealability
Rubber washer gaskets have excellent sealing performance and can effectively stop the leakage of liquid, gas or dust. They can fill in and fill the tiny gaps between the connectors and workpieces to ensure the sealing of the connection.
Cushioning and shock absorption
Rubber gaskets gaskets have good elasticity and flexibility, can play a buffer and shock absorption in the connection parts. They can absorb and reduce the impact of vibration, shock and vibration on the connection and workpiece to extend its service life.
Corrosion and wear resistance
Rubber washer gaskets are usually made of corrosion-resistant rubber materials, which can work stably for a long time in harsh environments. They have good abrasion resistance and can withstand high pressure and friction.
Temperature and chemical resistance
Rubber washer gaskets can work in a wide range of temperatures, from low to high temperatures there are applicable material options. In addition, they usually have good chemical resistance and can withstand corrosion and erosion of a wide range of chemicals.
Material Selection
Material selection for rubber gasket shims is based on the specific needs of the application. Common rubber materials include styrene butadiene rubber (NBR), fluoroelastomer (FKM), silicone rubber (VMQ) and ethylene propylene diene rubber (EPDM). Selection of the appropriate material depends on several factors:
Working environment
Considering factors such as temperature, pressure, humidity, and chemicals, select rubber materials with appropriate resistance to temperature, pressure, and chemical stability.
Sealing requirements
According to the required sealing performance, select rubber materials with better elasticity and compression deformation characteristics.
Service life
Considering the requirement of service life, select rubber materials with good wear resistance and anti-aging properties.
Cost factor
According to the budget and cost control needs, choose the appropriate rubber material.
The scope of application
Rubber washer gaskets are widely used in various fields, including but not limited to the following aspects:
Mechanical engineering
Rubber gasket gaskets are commonly used in the connection parts of mechanical equipment, such as pipelines, valves, pumps and so on. They can provide reliable sealing performance to prevent liquid or gas leakage while reducing vibration and noise.
Automotive industry
Rubber gaskets play an important role in automotive manufacturing and maintenance. They are commonly used in the engine, transmission system, braking system and suspension system, etc., for sealing and vibration damping.
Electrical and Electronic
Rubber gaskets are also widely used in electrical and electronic fields. For example, in cable connectors, battery boxes, switches and sockets and other equipment, rubber gaskets gaskets can provide waterproof, dustproof and anti-vibration function.
Chemical and petroleum industry
As rubber gasket gaskets have good corrosion resistance, they are commonly used for sealing parts in chemical and petroleum equipment. For example, the use of rubber gaskets in pipeline connections, tanks and valves can ensure the safe sealing of liquids and gases.
The use of precautions
In the use of rubber gasket gasket, need to pay attention to the following aspects:
Material compatibility
Ensure that the selected rubber material has good compatibility with the contacted liquid or gas to avoid chemical reaction or corrosion.
Installation correctness
Ensure that the rubber washer gasket is correctly installed on bolts, screws or other connectors to avoid over tightening or loosening.
Maintenance and Replacement
Regularly check the wear and aging of the rubber gasket gasket and replace it when necessary to ensure sealing performance.
Temperature and pressure limitations
Follow the temperature and pressure limits of the rubber gasket gasket to avoid exceeding its tolerance range.
Summary
As an important sealing element, rubber gasket gasket has excellent sealing performance, cushioning and vibration damping function, widely used in machinery, engineering and industrial fields. Choosing the right rubber material, correct installation and maintenance of rubber gasket gasket can improve the performance and service life of the equipment and ensure the reliability of the seal.
