A study on reducing power consumption of the centrifugal fan for the negative pressure adsorption wall climbing robot

Abstract

Abstract In order to solve the problems of ship wall climbing robot’s great power consumption and high noises, a new approach to reducing power consumption and noises of the centrifugal fan was investigated. Firstly, the relationship between the air volume of a centrifugal fan and ship’s dip angle of the outer wall is obtained by analyzing force condition of the robot and the theory of negative pressure adsorption. Furthermore, by means of researching the process of fan’s speed-regulation through changing DC 0-3.3 of fan’s driver. We get the relationship between speed-regulation voltage after D/A convert of fan’s driver and ship’s dip angle of the outer wall. We proposed a control system that can automatically detect ship’s dip angle of the outer wall and adjust the output power of the centrifugal fan. Finally, the result of reducing power consumption and noises was tested effectively.
