Scope
GB/T 35838-2018 is the English-translated version of 平移式喷灌机变量控制系统.
GB/T 35838-2018 covers the variable rate control systems fitted to moving lateral (linear move) irrigation machines. It sets out the terms and definitions, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage for these systems.
The control system monitors the synchronous swing angles between spans, the attitude and the travel speed of the machine and processes those data in real time; it is made up of a monitoring unit, a control unit, a drive unit and a feedback unit.
The document also defines the variable range of rainfall depth along the direction of travel and the spray uniformity coefficient, and refers to GB/T 19797-2012 for water distribution uniformity and to GB 5226.1-2008 for electrical safety.
Makers of irrigation equipment use it. It was issued on 6 February 2018 and has applied since 1 September 2018.
