Page 34: Boom Manifold
L P H A 2 5 0 0 S P R A Y I N G This chapter sets out the principle of normal circulation, semi-continuous and return spray. Choosing the type of nozzle and working pressure, refer to the ‘’Spray Technique’’ manual. 4 - 1 P R I N C I P L E O F C I R C U L AT I O N NORMAL CIRCULATION The mobile unit is equipped, as standard, with semi-continuous circulation. -
Page 35: Semi-Continuous Circulation
A L P H A 2 5 0 0 SEMI-CONTINUOUS CIRCULATION Semi-continuous circulation is generally suitable for delivery lower than 200 l/ha. Because of a cir- culation rate two or three time greater than that in normal circulation, there is no sedimentation of the products in the piping and therefore no blocking of nozzles. - Page 36 A L P H A 2 5 0 0 In comparison with Normal Circulation, there is the addition of a supplementary stream of liquid in the boom piping and this stream returns to the tank (CN), including when spray stops. During spray, the pump delivery is distributed between : - The spray boom equipped with nozzles.
