The difference between the Glauci ring and the Styphon

Stern seal is generally composed of a rubber O-ring and PTFE ring combination. The O-ring is the force element, which provides sufficient sealing force and compensates for the PTFE ring. Suitable for hydraulic cylinder piston rod with seal. The seal is a single-acting seal, which is divided into a piston seal and a piston rod seal. The seal has the advantages of low friction, no crawling, small starting force, high pressure resistance, and simple groove structure.

  StefonGenerally by a rubber O-ring and PTFE ring combination. The O-ring is the force element, which provides sufficient sealing force and compensates for the PTFE ring. Suitable for hydraulic cylinder piston rod with seal. The seal is a single-acting seal, which is divided into a piston seal and a piston rod seal. The seal has the advantages of low friction, no crawling, small starting force, high pressure resistance, and simple groove structure.

The most fundamental difference between the Glaine ring and the Stel seal is that the Stel seal is a single-acting sealing ring, which can only seal the pressure in one direction; the lattice ring is a double-acting seal, which can seal the pressure in two directions;

The working conditions of the Glea circle are:

Working pressure: 0-40 MPa;

Reciprocating speed: less than 5 m/s;

Working temperature: -35~120 degrees when the material is nitrile rubber, and -20~200 degrees when the material is FKM;

Working medium: hydraulic oil, gas and water;

After understanding the working conditions, let's talk about the following installation steps:

Avoid damaging the sealing lip as this can lead to leakage before use. Pay special attention when installing.

1. According to the specific requirements of the installation, the sharp edges need to be deburred and rounded, and chamfered.

2. Thread, guide ring groove, etc. Should be covered because the Liaoning ship cannot pass through grooves, holes and rough surfaces.

3. Dust, dirt, debris and other foreign matter must be removed carefully and slowly.

4. The cylinder, piston, piston rod and seal should be coated with grease before installation, and consider matching with the sealing medium.

5. In hot oil or hot water (about 80 ℃-120 ℃), the roller skating circle will easily expand and return to its original state.

6. When using tools for installation, it is necessary to use soft materials (such as polyamide) without any sharp corners.
