The Principle Of Atomizing Effect Of Trigger Spray B
This nozzle has a low-pressure drop of the fluid and sometimes draws fluid into the nozzle due to the suction of the atomizing air nozzle (siphon nozzle).
This type of nozzle may require more atomizing air and higher pressure drop than atomizing air because mixing and atomization of the liquid occur outside the nozzle.
When air and liquid perfume pass through the nozzle, the perfume breaks up into tiny droplets and mixes with the air.
A restriction at the end of the nozzle called a “venturi”, accelerates the mixture of air and liquid,
causing the liquid to disintegrate and the air to disperse the liquid widely.
During the upward stroke, the internal pressure of the small pump presses the cup against the barrel so air cannot pass through the nozzle.
When the trigger is first pulled and the piston is pushed in, there is no liquid to pump out; there is only air in the cylinder chamber.
You must force air through the pumping mechanism before you start spraying the cleaning fluid.
The first time you use the gun, you will need to pull the trigger a few times to spray cleaning fluid.

In particular, when using a 2-way valve without a vent, the residual pressure inside the gun will not be released even when the air is still,
so the needle valve will remain open and fluid flow will continue.
A valve is not required in the air path of the pressurized supply tank as fluid is constantly pressurized and supplied to the spray gun.
In a spray mechanism, a one-way valve between the pump and the nozzle,
the nozzle is a kind of cup that fits over the end of the barrel.
The automatic spray gun in this column is a “two-fluid nozzle” that mixes two fluids: liquid and compressed air.
The main function of the automatic spray gun is to grind the liquid into small particles and distribute it evenly by blowing compressed air around it.
The perfume spray pump uses the principle of atmospheric balance to spray the material into the bottle by pressing.
The pressure is larger and the pressure is reduced, forming a local negative pressure area.
This type of spray nozzle uses high-frequency vibrations (20-180 kHz) to achieve a narrow droplet distribution and low-velocity liquid atomization.
Use a smaller agitator tip if agitation is insufficient at correct spray pressure and bypass valve closed.
Since the on/off air and the atomizing air are cut off simultaneously by the same solenoid valve,
large droplets called saliva may form when the atomization is stopped.
