Question 102Refrigeration/AC - QMED70% to pass
When installing a mechanical shaft seal on a refrigeration compressor, extreme care must be taken to prevent what from happening?
AI Explanation
The correct answer is D) dirt and foreign particles from coming in contact with the highly polished sealing surfaces.
When installing a mechanical shaft seal on a refrigeration compressor, extreme care must be taken to prevent dirt and foreign particles from contacting the highly polished sealing surfaces. This is because any contaminants on these surfaces can cause uneven wear, leakage, and premature failure of the seal. The sealing faces need to maintain a perfect finish to ensure a tight, leak-free seal. The other answer choices are incorrect as they do not address the critical need to protect the sealing surfaces from contamination during installation.
