How to improve the performance of piston combined seal structure? A good combined piston seal is a main seal ring made of polytetrafluoroethylene adding filler, and the other is a combination of O-shaped elastic seal rings, which plays the role of secondary seal.
1, how to improve the performance of the piston seal structure?
1. The traditional U-shaped section can be redesigned through the dynamic lip design without sharp edges, which is conducive to rolling, increasing U-shaped structure and improving flexibility;
2. Using NBR or polyurethane instead of plastic material extends the service life of the sealing ring, and can be used normally in the air of Wu lubrication.
Second, what are the technical parameters of piston seals improved by technology?
1. Pressure ≤(MPa) : 40
2. Speed ≤(m/s) : 2
3. Temperature: -45/200
4. Material: NBR/PTFEFK
5. Medium: hydraulic oil, flame retardant liquid, water, gas
6. Application: Standardize cylinder, energy storage, hydraulic press
3, do you know the precautions for installing seals?
Before construction, all sharp edges and rough edges on pipe trenches and shafts must be removed to avoid damage to hydraulic seals; Seals are easier to install if oil or grease is applied.
