A Double Shaft Seal for the Compressor Refrigerator |
 |
 |
|
A shaft seal is the most fragile part of the industrial refrigeration system because 85% of mechanical seals fail prematurely and unexpected. Therefore mechanical seal failure continues to be the single greatest problem in the compressor operation. RM Support developed a perfect solution: a double shaft seal with pre-warming system.
The double shaft seal, also known the double barriers seal, has two seals, primary and back-up seal in one housing. Seals are cooled by their own cooling system, when the primary seal will fail the back-up seal will take over, in the same time the warning system will be activated. . Refrigerant (e.g. ammonia gas) will not leak to the atmosphere and the production can continue.
Read about a role of a double shaft seal in the refrigeration process and about blistering and reasons why shaft seals fails.
