This article explores the specific sealing structural features of mechanical seals used in reactors, examines sealing failure issues, and develops scientific strategies to extend the service life of these seals. This approach plays a positive and effective role in maximizing the comprehensive application value of reactor machinery, keeping it free from failures, and enhancing its operational efficiency.

Thoroughly inspect the mechanical seal, as well as the auxiliary equipment and pipeline installation, to ensure that they are complete and meet the technical requirements.
All seals will eventually leak, but it’s crucial to identify the root cause. Let’s take a look at some common causes of leakage.
A mechanical seal is a device used to seal the fluid medium between a rotating shaft and the machine housing.
The concentrated caustic solution circulation pump in the compression system of the ethylene plant is the bottom-of-tower circulation pump for the caustic scrubbing tower. It pumps the caustic solution—after it has been treated by caustic scrubbing of the cracked gas—up to the top of the tower, enabling the caustic solution to be recycled. In actual operation, this pump frequently experiences leaks. The mechanical seal starts to leak slightly about a week after installation and operation, and within one to two months, the leakage increases significantly, making the pump unusable. This seriously affects the plant’s ability to meet environmental standards and maintain long-term stable operation.
