Experimental Study on the Lubrication Behaviors of Seawater-Lubricated Thordon Bearings
Seawater lubricated thordon bearing is one of the most appropriate bearings widely used in submerged pump for drainage. The apparatus for studying the lubrication behaviors of the seawater lubricated thordon bearings has been devised and established in the paper. The experimental studies on the tribological properties of the thordon bearings have been conducted under different load and velocity using the apparatus. Effects of load and velocity on friction coefficient of the thordon bearings have been estimated. The experimental results show that the friction coefficient decreases with increasing velocity; the friction coefficient decreases gradually at first and then decreases sharpy with increasing load; the friction coefficient increases sharply with the rising temperature. The experimental results also indicate that there is an appropriate bearing clearance for which the friction coefficient is up to minimum.
