| Abstract: | This paper introduces the principles and theoretical calculations of the static pressure and anti-dipping method and the empirical study of the parameters of different structures.Results show that the properties of the static pressure and anti-dipping device are mainly dependent on the strength of the springs,the range of the valve and the size of the membrane.To ensure accurate and precise use of the insecticide,the variable coefficient of the flow rate of the sprayer must be smaller than 2%. |
