VENTURI AIR INDUCTION NOZZLE CHARACTERISTICS FOR MOTORIZED KNAPSACK MIST BLOWER
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 53
Abstract
One of the most essential components of motorized knapsack is the spray nozzle. This study evaluated the droplet spectrum of venturi air induction nozzle [available in the market] under various working pressures. In laboratory, droplet spectrum, using a droplet particle size analyzer and was measured with the operating pressure of 4500, 5000, 5500 and 6000 rpm. The results showed that: the droplet spectrum was affected by the nominal flow and by the liquid pressure. The motorized knapsack mist blower with venturi air induction nozzle gave the highest discharge of 1,842 ml min-1 at 4500 rpm and IV level of dosage. The NMD observed for different combinations of orifice sizes of 1.5 mm to 6.5 mm, were the droplet size increased from 15 to 21 µm respectively. The engine rpm from 5000, droplet size [VMD] increased from 88 to 139 µm with increasing the orifice size from 1.5 to 3.0 mm respectively. The uniformity coefficient for spraying jet nozzle is 5.6 to 7.4 with increasing the engine rpm from 4500 to 5000 rpm and decreases to 5.7 with increasing the engine rpm to 6000 rpm respectively.
