How to evaluate the performance and life of shaft seals
Sealing effect
Observe whether there is leakage. The ability of the seal to prevent fluid leakage can be judged by visual inspection, using a leak detection instrument, or performing a pressure test under specific conditions.
Friction and wear
Check the wear of the shaft and seal contact surface. Less wear usually indicates better seal performance and possibly longer life. This can be evaluated by measuring the change in shaft diameter, observing scratches and grooves on the seal surface, etc.
Temperature change
Monitor the temperature at the shaft seal during operation. Excessive temperature may mean excessive friction or seal failure, affecting the performance and life of the seal.
Pressure stability
Test the ability of the seal to maintain under different operating pressures. Stable sealing performance should still effectively prevent leakage when the pressure changes.
Material compatibility
Investigate the compatibility of the sealing material with the sealed fluid and the surrounding environment. If the material corrodes, swells or ages, it will affect the seal performance and life.
Operation speed adaptability
Determine the working condition of the shaft seal at different speeds. Shaft seals that can maintain good sealing performance over a wide speed range are preferred.
Anti-pollution ability
Evaluate the sealing effect and life of the seal in the presence of impurities, dust and other contaminants.
Ease of installation and removal
Although this is not a direct indicator of performance and life, shaft seals that are easy to install and remove facilitate maintenance and replacement, indirectly affecting the overall cost and effect of use.
Historical data and experience
Refer to the usage and life data of shaft seals in the same or similar application scenarios to understand their performance in actual work.
