Question 136Refrigeration/AC - 1st Asst/Chief70% to pass
The carbon seal ring of a refrigeration compressor crankshaft mechanical seal is held in position against the stationary ring face by using what device?
AI Explanation
The correct answer is C) spring.
The carbon seal ring of a refrigeration compressor crankshaft mechanical seal is held in position against the stationary ring face by a spring. The spring provides the necessary force to keep the carbon seal ring pressed against the stationary ring face, ensuring a tight seal and preventing refrigerant leakage.
The other answer choices are incorrect because: A) a snap ring is used to hold other components in place, not specifically the carbon seal ring; B) a woodruff key is used to transmit rotational force, not to hold the carbon seal ring; and D) a thrust washer is used to support axial loads, not to hold the carbon seal ring in position.
