Excessive leakage in packing systems often indicates wear. Packing systems are designed to prevent fluid or gas from escaping through the shaft or other moving parts. When these systems become worn, they can no longer create an effective seal, leading to increased leakage. This wear can occur due to prolonged usage, poor maintenance, or the effects of the operating environment, such as high pressure or extreme temperatures. Monitoring for excessive leakage is crucial as it not only signifies the potential failure of the packing but also can lead to more significant issues in the machinery involved, such as pressure loss or environmental hazards.

In the context of packing systems, while imbalance, misalignment, and contamination can affect machinery performance, they are not the primary indicators of excessive leakage. Excessive leakage is primarily a direct consequence of the wear and tear of the packing material itself. Recognizing wear early on can help prevent further damage and maintain efficiency in the equipment.
