First, what is the working principle of electric spray machine
Electric spray machine is an electric spraying equipment, mainly used to disperse the coating into a mist spray on the surface of the coating, many fields will use electric spray machine, then what is the principle of electric spray machine?
1. Structure of electric spraying machine
Spraying machine is mainly composed of feeding device, spray gun and atomization source, and the atomization source of electric spraying machine is mainly composed of motor and high pressure pump. 2, the working principle of the electric spray machine.
When the electric spraying machine works, turn on the power supply, under the electric drive, make the piston stable and continuous reciprocating motion, because the piston is rigidly connected with the plunger in the paint plunger pump, and the piston area is larger than the plunger area, so that the suction of the paint supercharging; The pressurized coating is transported to the spray gun through the high-pressure hose. When it passes through the nozzle, due to the sudden change of pressure inside and outside the muzzle, it expands rapidly and atomizes, forming a very fine fog logistics, which sprays to the surface of the coated material and forms a coating layer.
Two, the characteristics of electric spray machine
Traditional sprayer is to use compressed air to coating atomized spray, spray fast speed lead to coating of excessive spraying and serious rebound phenomenon, and brought back a lot of paint and float in the sky, the paint is responsible not only waste a lot of paint, and cause serious pollution to the air, the phenomenon of coating surface is prone to imperfections, electric sprayer is different, The characteristics of the electric spray machine are:
1, because there is no compressed air, so can eliminate the water in the compressed air, oil and other impurities brought about by the disadvantage, will not be caused by the loss of coating caused by the compressed air in the surface of the coating.
2. The pressure of the coating is high when the electric spraying machine is spraying, which can be closely combined with the surface of the coating, and can penetrate into the fine holes, so that the coating has good adhesion. 3, the efficiency of the electric spray machine is higher, a spray can achieve a thicker film, can reduce the number of spraying.
