Introduction
GB/T 20183 "Mechanical spray equipment for plant protection" is intended to describe the test methods for mechanical spray equipment for plant protection: It is planned to consist of four parts:
Grouped into:
--- Part 1: Test method for spray nozzles for sprayers: The purpose is to describe the test method for the spray accuracy of hydraulic nozzles for sprayers:
--- Part 2: Test methods for evaluating the horizontal lateral distribution of hydraulic sprayers: The purpose is to describe three test methods to evaluate the horizontal lateral distribution of hydraulic sprayers:
Horizontal distribution of the amount of pesticide applied by the same type of sprayers:
--- Part 3: Test method for evaluating the performance of the system for regulating the amount of liquid applied per unit area: The purpose is to describe the amount of liquid applied per unit area:
Test conditions, test methods and calculation methods for quantity regulation systems:
--- Part 4: Test method for stirring the liquid tank: The purpose is to describe the performance of the stirring system in the liquid tank of plant protection machinery:
Methods:
Mechanical spray equipment for plant protection
Part 1: Test methods for sprayer nozzles
1 Scope
This document describes the test procedures and methods for assessing the spray accuracy (except droplet characteristics) of hydraulic nozzles for sprayers:
