IMPROVEMENT OF UNIFORMITY OF SPRINKLED WATER DEPTH FOR SPRINKLER SYSTEM DESIGN

摘要

PROBLEM TO BE SOLVED: To provide a method for improving uniformity of sprinkled water depth for sprinkler system design by forming a space for sprinkled water patterns, and actually measuring and analyzing the patterns for measuring and drawing the sprinkled water pattern models for sprinklers.;SOLUTION: This method for actually measuring and drawing sprinkled water pattern models for a sprinkler 1 forms a space, which is unaffected by wind, in a radial direction which is unaffected by wind, and measures and analyzes the sprinkled water patterns in the radial 1 direction, to draw the pattern models. It is preferable to form a space facility 12 unaffected by wind in a radial direction, arrange measuring cans 9 in one direction at constant intervals at a distance slightly longer than the sprinkler discharge radius from the sprinkler 1 position, rotate them at 360° for a given time, measure depth of water in each can 9 as the sprinkled water depth at each radius, draw iso- depth arc of 360°, and prepare the sprinkled water pattern model, based on the measurements.;COPYRIGHT: (C)2000,JPO
