Abstract:

More than ten kinds of the pesticide injection syringes were compared,their designs,kernel techniques and mechanisms were studied.Their merits and demerits were compared.A new pesticide injection syringe-6HZ.D625B was designed.Its operating pressure≤25 MPa,pressure maintenance≥10 min,pump discharge volume is 2±0.2 mL/once,injection velocity is 1~2 s/once(done by hand),its weight is 6 kg,with six syringe needles.
