DEVELOPMENT OF AIR BLAST SPRAYER INSTALL WITH SIDE CAR

Abstract

The aims of this research were development and determine field capacity and efficiency of air blast sprayer install with side car. The air blast sprayer consist of centrifugal blower, angle adjustment, wind distributor, LPG engine, hollow type fluid injector and DC pump that installed with side car. The result show the air blast sprayer install with side car working at blower speed was 1,950 rpm, travel speed was 4 km/hr, field capacity was 10 rai/hr, chemical flow was 240 liters/hr, LPG consumption was 1.2 kg/hr, droplets density was 19.33 and droplets size was 61.2 micron. The cost of air blast sprayer install with side car was 40,000 bath and return period were 4 months and 12 days.
