he relentless demand for operational efficiency and equipment reliability in mining places immense
importance on effective shaft sealing. This article from shaft specialist Sealryt explores the benefits of a Double Flush Inlet configuration, validated through Computational Fluid Dynamics (CFD) simulations, to ensure optimal sealing in large rotating equipment. By addressing common challenges and identifying best practices, a spokesperson from the company said: “we aim to empower mining companies to prevent costly leaks and extend equipment lifespans.”
In-out
THE IMPORTANCE OF EFFECTIVE SHAFT SEALING Large rotating shafts are critical in mining operations, primarily driving equipment such as slurry pumps. A reliable sealing mechanism is critical to maintaining equipment integrity, avoiding downtime, and preventing hazardous leaks. Lantern rings, a key component in sealing systems, act as reservoirs for pressurised barrier fluids, ensuring a robust seal within the stuffing box. Maintaining a pressure differential of at least 15 psi between the flush fluid and the process/media is essential for consistent performance.
