航空静电喷雾装置的改进及效果试验
Improvement and experiment of aerial electrostatic spray device
摘要
Abstract
Aerial electrostatic nozzle structure and performance are the main factors of aerial electrostatic spraying effect. Aimed at aerial electrostatic single-nozzle applied in the light plane, electrostatic electrode, nozzle material, nozzle processing technology, high-voltage wires and electrode connection, rotating screw joints, overflow valve body and so on were improved and redesigned. The theory and experiment of the nozzle's atomization charged mechanism and performance were studied. The comparative test of pine caterpillars control had been carried out on the improved electrostatic nozzle mounted on the light bee plane with the original electrostatic nozzle and the traditional fan nozzle. The results showed that the flow rate was high and even and the maximum charge-to-mass ratio reached 2.26 mC/kg when the improved aerial electrostatic nozzle applied in pressure of 0.35 Mpa, diameter of 0.8 mm, spray angle of 96°. Compared with the conventional aerial fan nozzle, the improved nozzle increased the droplet deposition by 18/cm2, shortened the operation time, reduced the pesticide quantity by 5.22 L/hectare and improved the effective prevention rate by 33.8%. Thus the new Aerial electrostatic nozzle can fully meet the need of air spray and achieve satisfactory effect in the prevention of pests and diseases.关键词
