Bearing and Shaft Seal Water Conditioning Systems


WQP-SS-High-Resolution

Thordon has developed a self-contained supply, conditioning and monitoring package to ensure that an adequate supply of clean water is consistently being delivered to both the seal and the bearings.

The Thordon Water Quality Package is designed to supply water to the main guide bearing for lubrication and cooling at a minimum flow rate of 0.3 litres/minute/mm (2 US gallons/minute/inch) of shaft diameter and to condition water from the water supply by removing suspended solids larger than 100 microns (0.004” ) and with a specific gravity of 1.2 or higher; separation to 80 microns (0.003”) is achievable using the 75-150 l/min (20-40 GPM) unit. A flow alarm is incorporated to alert the operator to any low water flow condition to the bearing. The Thordon Water Quality Package is designed to operate on a stand-alone basis, or can be fully integrated into the control and monitoring systems to allow operation in an unmanned machinery space.

Thordon offers three Water Quality Packages in configurations designed to deliver flow to suit a wide range of shaft sizes, and provide an appropriate degree of installation redundancy. Thordon can, if required, work with integrators, designers and builders to meet special needs for specific installations.

    Genesis Energy's Tekapo A Plant Completes Thordon Bearing Upgrade

    Sep 28, 2020
    New Zealand’s Genesis Energy has completed a first phase refurbishment of the 190MW hydro power plant at Lake Tekapo, in the South Island. Through its Auckland-based distributor Henley Group, Thordon supplied ThorPlas-Blue wicket gate bushes, Thorseal lip seals (which replaced nitrile rubber sealing rings in the lower and intermediate wicket gate bearings), and SXL operating ring wear pads. A new SXL turbine guide bearing, upgraded with better tolerances, was designed, supplied and installed. The shaft seal carbon segments were also replaced with SXL segments.
