The pan plug seal is a kind of seal ring with a wide range of applications. It is composed of a corrosion-resistant spring (generally stainless steel) and a seal ring made of a U-shaped filled PTFE material. When the system pressure is zero, the spring provides the initial pre pressure. When the system pressure is increased, the U-shaped cavity is filled with pressure medium, making the lip close to the cylinder wall,
In this way, the seal has good sealing performance in the whole process of pressure change.
Advantage: low friction.
Accurate positioning, no crawling.
It can bear the drastic change of temperature and has good high temperature resistance.
Good corrosion resistance.
The medium has good adaptability and can adapt to most fluids and chemicals.
Seal made of proper materials can be used in food and medical industry.
Working limit:
Pressure: 700kg / cm2
Temperature: - 180-300 ℃
Linear speed: 20 m / S
Application:
Because this kind of seal has good adaptability to medium, it is widely used. In addition to conventional hydraulic system, it can also be used in medicine, chemical industry, food, metallurgy, aerospace and various servo systems.
Compared with oil seal, Teflon universal plug seal is more wear-resistant, pressure resistant, corrosion-resistant and self tightening, which is the best alternative to oil seal
