説明

When a spring-loaded scraper blade thrusts on a vessel wall, the force exerted on the blade was considered as the sum of the drag force of the blade and the friction force between the tip of the blade and the vessel wall. The drag force was obtained by two kinds of experiment : <BR>(1) Loaded force was varied by the length of a coil spring, and the drag force of the blade was obtained by extrapolating the force to zero loaded force.<BR>(2) Clearance between the tip of the blade and the vessel wall was changed by the diameter of a roller fitted on both ends of the blade tip, and the drag force of the blade was obtained as the force at zero clearance.<BR>The experimental drag force was compared with the theoretical value. The experimental equation of power consumption of the blade was obtained as the sum of the power against the drag force of the blade and the power against the friction force between the tip of the blade and the vessel wall.
