1. The structure and function of electric sprayer
Electric sprayer is a kind of sprayer, which is driven by battery to work, with high efficiency, low labor intensity and convenient use And other advantages, then what is the structure of the electric sprayer?
1. Nozzle
Also called nozzle, there are three types: single nozzle, double nozzle and four-eye nozzle. The beads are small and can be used for small-scale spraying; the double-nozzle sprays have larger fog clusters and extremely fine mist beads, which are suitable for large-scale spraying; the four-eye nozzles can be adjusted in tightness and are suitable for spraying tall trees with crowns or fruit trees.
2. Barrel body
The barrel body is a container for liquid medicine and water. The spray boom can also be fixed on one side of the body.
3. Spray boom
It is used to extend the spraying distance, and there is also a handle switch to control the spraying operation.
4. Base
The base is located in the lower part of the barrel, which is used to fix the battery and the water pump, and there is a power switch on one side of it .
5. Battery
The battery is used to power the sprayer, and there are two main specifications: 12V/12Ah and 12V/8Ah.
6. Water pump
The water pump generates a strong pressure difference through high-speed operation, sucks water from the water inlet pipe, and sprays it from the water outlet pipe to form a high-speed water flow , complete the spraying operation.
Second, what is the principle of the sprayer
The sprayer is to spray the water or liquid inside into a mist and spray it evenly on other objects , is an indispensable and important agricultural tool for the control of pests and diseases. There are four working principles of the sprayer:
1. Bernoulli’s principle: in the fluid, the flow rate is large, the pressure is small; the flow rate is small, the pressure is strong, the fluid will Automatic flow from high pressure to low pressure. When passing through the three-pronged tube, the water flowing at a low speed flows to the air flowing at a high speed, and the water is torn into small drops by the high-speed air, and it becomes a water mist when it is sprayed out.
2. The principle of high-speed water flow breaking into small water droplets after encountering obstacles: water is pressed into a thin tube to cause high-speed water flow, and high-speed water flow will break into small water droplets after encountering obstacles.
3. The liquid is thrown out by centrifugal force: the high-speed rotating atomizing disc uses centrifugal force to throw out the liquid and tear it into small droplets.
4. Principle of ultrasonic atomization: Vibration can cause waves on the water surface. The vibration frequency of ultrasonic waves is very high, so the wave of its waves is very small, and the small water droplets are also very small. These small water droplets become fog.
