Knapsack thermal fogging machine works

How to knapsack thermal fogging machine work?The following will inform you the detailed  process of knapsack thermal fogging machine .When the operator down pushed the joystick or lever when the piston rod through the rod up and down in the pump cylinder reciprocating stroke 40-100 mm. When the stopper pole row, cups upwardly from the bottom, below the cups and cups composed of cylinder cavity volume is increasing, and the formation of a partial vacuum. Then the liquid surface and the liquid in the barrel chamber under a pressure differential valve punch entered along the inlet pipe into the pump cylinder, complete the absorption process. When the piston rod down, the downward movement of the cup from the pump cylinder of the liquid is squeezed, so that the liquid pressure suddenly increased. In the action of this pressure, the inlet valve is closed, the valve is pushed open, the liquid through the valve into the air chamber. The air is compressed air chamber, put pressure on the liquid, turn on the switch lever into the nozzle by spraying liquid is atomized spray. Fog nozzles of the hollow cone, including tangential inlet nozzle or with a rotary water water film spin nozzle core, the liquid from the tangential inlet passage or from a rotary water film, spin the water passage into the core of the spiral vortex chamber, the liquid occurs rotating the spray hole in the axis of the vortex chamber, thereby forming a hollow cone of the liquid ejected film, which is then pulverized into droplets. 

As for the core with water sprinklers slot spin, spin the water from the liquid core axial core inlet passage through the water after the water tangentially into the core by the rotation center of the front of the pit and the nozzle piece consisting of vortex chamber. Nozzle slit nozzle, which end portion of said cylindrical flow into the half spherical, external opening a V-shaped cut-outs on both sides of the V-shaped groove of the arcuate surface of the two streams injected collide with each other in the direction of the grooves cut generation liquid film, film and media still formed by the action of the air fan fog stream.
