Agricultural sprayer

Agricultural spraying machine is a machine liquid dispersed, is a kind of spraying machinery, agricultural, medical and other uses points (such as industrial), agricultural classification for plant protection machinery agricultural machinery. Commonly known as human driven sprayer, power (engine, motor) driver for sprayer. The spray machine according to the working principle hydraulic, pneumatic and centrifugal sprayer. According to carry way holding, backpack, shoulder type, pedal type, stretcher, transportable, self-propelled, vehicle type, hanging type separation, and aerial spraying machine.

2 principles of editing

A is the Bernoulli principle. The principle of Bernoulli said that at the same flow, velocity, pressure flow rate, pressure big. Low pressure fluid will automatically flow from the high pressure. In the trigger sprayers tube (specific graph cannot be drawn out, their understanding), low flow to the high speed of the flow of air. The water is high speed air to tear into droplets of a droplet (ideas out of the water, the tap water column is beginning to slow,; but later speed increases gradually becomes a drop of a drop). These small water droplets sprayed out after a fog.

The second use is put water into the tube caused by high velocity flow, high flow barriers after splitting into small droplets. Cases like the tap next to large stuffed his fingers. Sprayer household use this structure, low cost.

The third is to make water (water is the charge on the dielectric), the water into droplets repel each other with the same charge. This method is very small droplet. The same principle is also used to give the car paint.

The fourth is the ultrasonic backpack garden sprayers. Vibration can cause "spray" on the surface of the water, the ultrasonic vibration frequency is very high, so the "wave" of the wavelength is very small, so its "spray" -- small droplets are very small, these small water droplets into the fog. The hospital throat spray machine treatment of respiratory diseases is to use ultrasonic .
