Precautions for Using Mechanical Seals on Reactor Vessels

1. Check Operating Conditions Before Installation
Before selecting and installing a mechanical seal, confirm the actual operating conditions of the reactor, including medium characteristics, temperature, pressure, vacuum level, rotation speed, and chemical compatibility.
2. Ensure Correct Seal Selection
Select the appropriate mechanical seal type, materials, and design according to the process medium. Consider corrosion resistance, high-temperature performance, pressure conditions, and whether the medium contains particles or crystallizing substances.
3. Cleanliness During Installation
Keep all seal components, especially sealing faces, clean during installation. Any dust, particles, oil contamination, or scratches on the seal faces may cause leakage or premature failure.
4. Check Shaft and Installation Accuracy
Before installation, check the shaft condition, runout, alignment, and surface finish. Excessive shaft vibration or misalignment can reduce seal life and cause leakage.
5. Avoid Damage to Seal Faces
The sealing faces are precision-machined components. Do not impact, scratch, or apply excessive force during assembly. Always handle seal faces carefully.
6. Lubrication and Cooling Requirements
For high-temperature or vacuum reactor applications, ensure proper cooling, flushing, or barrier systems are available when required. Insufficient lubrication or cooling may result in overheating and seal face damage.
7. Start-Up Procedure
Before starting the reactor, confirm that the sealing system is properly installed and that the cooling/flushing system is operating normally. Avoid dry running of the mechanical seal.
8. Control Operating Parameters
Do not exceed the designed pressure, temperature, or speed limits of the mechanical seal. Sudden pressure changes, temperature shocks, or frequent start-stop operations may shorten seal service life.
9. Regular Inspection and Maintenance
Regularly check for leakage, abnormal noise, vibration, and temperature increase. Replace worn sealing components promptly to prevent unexpected equipment downtime.
10. Proper Storage and Handling
Store mechanical seals in a clean, dry environment away from moisture, chemicals, and direct sunlight. Keep sealing faces protected before installation.

Important:
A mechanical seal is a precision component. Correct selection, proper installation, and suitable operating conditions are essential to achieve reliable sealing performance and long service life.
