摘要：

This paper makes a simulation analysis on three kinds of micro droplets jetting dispenser nozzle match type (the cone-cone match, sphere-cone match, sphere-sphere match). The key parameters of coordination including the average working pressure P, nozzle colloid flow time t0 the jet nozzle colloid duration are analyzed in order to acquire the properties of various match type. Conclusions was drawn based on the comparison between the different match type that sphere-sphere coordination is better able to dispense large viscosity colloid and reduce the angle in low viscosity; cone-cone coordination is not suitable for dispensing due to low speed of liquid ejection; sphere-cone coordination is suitable for dispensing colloid of lower viscosity. These findings are of great significance for the development of on-off valve jet dispensers.
