Dynamic seals are devices used to maintain a seal between moving or rotating parts. They are commonly used in areas such as hydraulic systems, pneumatic systems, engines and rotating equipment. The main function of dynamic seals is to prevent liquid, gas or other media from leaking from the connection and to prevent external impurities from entering.
Customizable rotary seals are available for corrosive environments and wide temperature range conditions to prevent leaks and protect equipment from dust, mud, water and other contaminants.

Diaphragms for diaphragm valves refers to the flexible diaphragm used as the main sealing component in the diaphragm valve, usually an elastomer diaphragm. The diaphragm acts both as a sealing element and as a moving part that opens or closes the valve. When the diaphragm is relaxed, it prevents fluid flow by sealing against the valve seat. When driven, typically by a hand handle, pneumatic or electric actuator, the diaphragm flexes or deforms, creating an opening that allows fluid to pass through.

Контактная информация
A dynamic seal is a component that is frequently found in mechanical and industrial equipment that stops liquids or gasses from leaking. They are made to effectively seal during movement to stop media leaks.
Mostly utilized on revolving or reciprocating parts like shafts, pistons, and valves, dynamic seals They typically have strong resistance to wear and corrosion and are composed of elastic materials, like rubber or polymer. Dynamic seals must adjust to shifting components without compromising sealing efficiency.
Seals, piston seals, shaft seals, etc.
The sealing ring is one of the most commonly used dynamic seals. It usually adopts a circular ring shape and is used to prevent liquid or gas from leaking through the axial direction. Piston seals are used to prevent medium leakage between the piston and the cylinder. Common types include piston rings and piston rod seals. Shaft seals are used to protect the seal between the rotating shaft and the external environment to prevent the leakage of lubricating oil or other media.
Dynamic seal selection depends on the application’s operating conditions and requirements. Because different working environments and media may have different effects on seals, such as high temperature, high pressure, chemical corrosion, etc. Therefore, when selecting dynamic seals, factors such as material tolerance, sealing effect, friction loss, etc. need to be considered.
Some dynamic seals can work in high temperature environments. For example, high temperature oil seals are commonly used in hydraulic systems and engines.
Some dynamic seals made of special materials can work in low-temperature environments, such as liquid nitrogen seals used in low-temperature liquid nitrogen storage and delivery systems.
Dynamic seals cope with high-pressure media, such as those used in high-pressure pumps or compressors.
For corrosive media, choose seals made of corrosion-resistant materials, such as polytetrafluoroethylene sealing rings, which are widely used in the chemical industry.
Dynamic seals are required to provide effective sealing on high-speed rotating components, such as shaft seals in wind turbines.
Dynamic seals are also used in the food and pharmaceutical industries.

(Sealing, wear resistance, heat resistance, elastic recovery, resistance to compression deformation, friction characteristics…)
The main purpose of dynamic seals is to provide an effective seal against leakage of liquid or gas. Therefore, good sealing performance is one of its most important mechanical properties. Sealing performance is usually measured by leakage rate, sealing pressure, sealing performance durability and other indicators. Its sealing performance is usually measured by leakage rate, sealing pressure, sealing performance durability and other indicators.
Износостойкость
Dynamic seals need to be in contact with moving parts when in motion, so their wear resistance is an important mechanical performance indicator. The wear resistance directly affects the service life and performance stability of the seal.
Heat resistance
In some applications, dynamic seals may be exposed to high temperatures, so their heat resistance is a key mechanical performance indicator. The quality of heat resistance affects the stability and sealing effect of seals in high temperature environments.
Эластичное восстановление
Dynamic seals should be able to return to their original shape and size after being deformed or stressed. Elastic recovery is one of the important mechanical properties to ensure the normal operation of seals.
Resistance to compression deformation
Dynamic seals should be able to maintain good shape stability and not undergo excessive compression deformation when subjected to pressure. The resistance to compression deformation is directly related to the sealing effect and service life of the seal.
Характеристики трения
The friction characteristics between dynamic seals and moving parts have a significant impact on their performance and service life. Proper friction characteristics can provide good sealing effect and movement performance.
