Principle of the spray nozzle

The glue is based on the principle of nozzle throttling mechanics principle, heating to melt the hot melt adhesive after the push pump flow to the glue dispensing hose and communicated with gun body, so that the internal space is filled with a fluid (hot melt melted); and then the electromagnetic valve through the gas conversion to control gun valve breaking, resulting in hot melt fluid with pressure ejected from the valve base through the nozzle, the velocity will form a partial contraction in the nozzle, so that the flow speed, static pressure decrease, eventually achieve a variety of spraying effect.
Note: the hydrostatic pressure (static pressure): in a relatively static state of the fluid, due to gravity or other forces, between the internal fluid and fluid and the vessel wall are perpendicular to the contact surface of the force, this force is called the static pressure of the fluid. With P said, unit N.
