ED ring is an elastomer seal used as an axial static seal. It is used in threaded oil ports and screw ends. Its cross-section remains almost constant under high pressure. Compared with ordinary O-rings, its advantages are:
The mechanical deformation of the cross-section is small, there is no relative movement during the pressure cycle, excellent sealing performance is maintained for a long time, and the working pressure can reach 60Mpa.
Advantages of ED circle:
High temperature resistance, oil resistance, chemical resistance, ozone resistance, weather resistance, anti-aging, chemical solvent resistance, smoldering property, excellent air tightness, and famous for its chemical resistance. Suitable for weak acids and weak bases.
Disadvantages of ED circle:
Intolerant to ketones, lipids, and nitrates;

ED sealing rings are suitable for installation on various mechanical equipment and perform sealing functions in static or moving conditions under specified temperatures, pressures, and different liquid and gas media. Various types of seals are widely used in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various types of instruments and meters. element.
ED sealing rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion seals, its resistance to gasoline and aliphatic hydrocarbon oils is particularly good, second only to polysulfide rubber, acrylate and fluororubber, but better than other general-purpose rubbers. It has good heat resistance, good air tightness, wear resistance and water resistance, and strong adhesion. The disadvantages are poor cold resistance and ozone resistance, low strength and elasticity, poor acid resistance, poor electrical insulation, and poor resistance to polar solvents. Suitable for automotive transmission oil, with good heat resistance and oil resistance, and stable performance in lubricants containing sulfur, phosphorus and chlorine additives. At the same time, it is resistant to aging, oxygen and ozone, UV resistance, and excellent air tightness. The disadvantage is that it has poor cold resistance, is not resistant to water, steam and organic and inorganic acids and alkali.

Many ED rings are produced using synthetic rubber materials. Therefore, the initially set compression amount and resilience of the product will cause permanent deformation after long-term use, and will gradually fail and cause leakage. It can be said that permanent deformation and loss of elasticity are the main reasons for the decline in sealing performance. So what are the causes of permanent deformation?
1. The relationship between compression ratio, stretch amount and permanent deformation of product materials
When producing this product, there are many kinds of rubber formulas, and even different formulas will produce compressive stress relaxation under compression. Generally speaking, compressive stress will decrease with time.
As the use time prolongs, the values of compression ratio and tensile amount will become larger, because the stress drop caused by rubber stress relaxation will also be greater, resulting in insufficient elasticity of the product and reduced sealing performance.
What are the causes of permanent deformation of ED rings?
If the use conditions permit, you should try to reduce the compression rate, which can alleviate product deformation. You can reduce the compression rate by increasing the cross-sectional size.
The degree of deformation of the product's cross-section is closely related to the hardness of the material. Under the premise of the same stretching amount, the hardness is large and the cross-section height is small. Therefore, on the premise of meeting the use requirements, a low-hardness material should be selected.
Due to the action of liquid pressure and tension, the product will gradually undergo plastic deformation after long-term use, resulting in a reduction in cross-section height and loss of sealing performance.
2. The relationship between temperature and product relaxation process
The use temperature is the cause of permanent deformation of the product. High temperatures can easily cause rubber materials to age. The higher the working temperature, the great
