The operating environment of the rotary shaft seal ring is complex and changeable, and its performance and service life are largely affected by these environmental factors. The following is a detailed analysis of the operating environment of the rotary shaft seal:

1. Temperature environment

The rotary shaft seal ring needs to maintain its good sealing performance and physical and mechanical properties within a certain temperature range. Sealing rings of different materials have different temperature tolerance ranges. For example:

Nitrile butadiene rubber (NBR) seals are usually suitable for the temperature range of -30 ° C to +100 ° C.

Fluororubber (FKM) seals can operate in a wider temperature range, generally -30 ° C to +200 ° C, and some high-end models even have a wider temperature range.

Polytetrafluoroethylene (PTFE) seals have extremely high temperature stability and can work in the range of -200 ° C to +260 ° C.

Therefore, when selecting the rotary shaft seal ring, it is necessary to select the appropriate material according to the temperature conditions in the actual working environment.

Two, medium environment

The rotary shaft sealing ring needs to be in contact with a variety of media, including water, oil, gas, chemicals, etc. Sealing rings of different materials have different tolerance to media. For example:

Nitrile rubber seal ring has good oil resistance and wear resistance, suitable for oil media.

Fluorine rubber sealing ring has excellent chemical resistance, can resist a variety of strong acids, alkali and organic solvent erosion.

PTFE seals are resistant to almost all known fluid media, including highly corrosive chemicals.

Therefore, when selecting the rotary shaft seal ring, it is necessary to consider factors such as the type of medium, concentration, temperature and pressure to ensure that the seal ring can work normally and prevent media leakage.

When the rotary shaft seal is working in mechanical equipment, it will be affected by mechanical forces such as rotation, vibration, and impact. These mechanical forces can cause the seal to deform, wear or damage. Therefore, when selecting the rotary shaft seal ring, it is necessary to consider its mechanical strength, wear resistance, fatigue resistance and other properties to ensure that it can maintain a stable sealing effect in a harsh mechanical environment.

Other environmental factors

In addition to the above factors, the use of the rotary shaft seal environment may also be affected by humidity, light, oxygen, ozone and other factors. These factors can cause the seal ring to age, harden or weather, thereby reducing its sealing performance and service life. Therefore, when storing and using the rotary shaft seal ring, it is necessary to pay attention to avoid the influence of these adverse factors and maintain its good performance and condition.
