기계공학 기계문제의 종류-공동현상(Cavitation), 스케일(scale), 수격현상(Water Hammering)(영문) [기계공학] 기계문제의 종류-공동현상(Cavitation), 스케일(scale), 수격현상(Water Hammering)(영문).pptx 목차 1.CAVITATION 2.SCALE 3.WATER HAMMERING 본문 Cause of Occurrence - Large suction head of pump. - Large friction loss of pump. - High velocity of impeller of pump. - Position of pump is higher than fountainhead. Solution - Make suction head and friction loss small. - Make the velocity of impeller small. - Install the pump lower than fountainhead. - Use double suction pump. - Control the water pressure inside tube higher than vapor pressure. - Make suction caliber big. - Install pump more than two. 본문내용 LEMS SOLUTIONS IDEA Plant Engineer Development Program IDEA REDUCING DAMAGE IDEA DEFINITION CAUSES SOLUTIONS IDEA IDEA MECHANICAL PROBLEMS Plant Engineer Development Program 1 Plant Engineer Development Program CONTENTS 1 2 3 Cavitation Scale Water Hammering Contents CAVITATION 2 Plant Engineer Development Program Cavitation 1 What is the Cavitation ?
