Scope

Scope: This document specifies the terms and definitions, product models and basic parameters, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of blade-type anti-frost machines (hereinafter referred to as "anti-frost machines"). This document applies to electric-driven blade-type anti-frost machines, primarily used in tea and fruit orchards and other crops. Main technical content: The theoretical anti-frost effective diameter of the anti-frost machine should be measured within a circular area below the anti-frost machine where there are no obstacles on the ground. The distance from the rotating plane of the blades at the bottom of the anti-frost machine to the ground is 6.8m. When measuring, the axis of the anemometer should be parallel to the airflow direction of the anti-frost machine. Determination of the anti-frost effective diameter of the anti-frost machine: At the test site where the environmental wind speed is ≤0.2m/s, the starting point is directly below the center of the anti-frost machine at a height of 0.5m from the ground, and the point where the measured wind speed is 0.5m/s is the end point. The length measured from the starting point to the end point is the maximum effective radius. Based on the maximum effective radius, the maximum effective diameter, that is, the anti-frost effective diameter of the anti-frost machine, is calculated.
