Evaluation of a carrier control valve for a direct nozzle injection system
Original language description
Environmental friendly pesticide application technologies, utilising direct injection systems and simple patch spraying, have become more important in recent years. During site-specific application, sprays are turned off over areas to be excluded and onover areas to be treated. Thus, to obtain spatially accurate applications, the spray patterns from nozzles have to be rapidly established. An electro-pneumatic carrier valve, in combination with a direct nozzle injection system, has been tested to determine its suitability for sitespecific application. Also, the effect of interrupting the flow of carrier fluid on the injection process has been assessed. A high-speed camera was used to study the valve response time and the development of the spray pattern. The increase in concentration of pesticide in the direct nozzle injection system was simulated by a NaCl solution, which was measured using a conductivity sensor. The reaction time of the electro-pneumatic valve was less than 32 ms ope
