How to maintain the garden sprayer

Garden sprayer due to ease of use, high work efficiency, more and more farmers love, has now become the main tool for pest control in the greenhouse. However, electric sprayer comparison "delicate", garden sprayer backpack  in the use of improper operation, maintenance is not timely, it is prone to failure. How to maintain, and can prolong the service life of the sprayer, the reporter interviewed specially engaged in spray sales work Han manager, he suggested that farmers should do the following.
First of all, the first formal use, check whether the connection leak. When in use, first install the garden hand sprayers  test, then pack medicament. Dosing must first agent after the water, liquid level can not exceed the safe water line. Before spraying, garden sprayer opened in advance, so that the barrel pressure rise to the pressure of work, in order to ensure the smooth spraying.
Secondly, garden sprayer after use, should first put the liquid medicine tank, hoses, spray rods and other parts clean, pay special attention to clear the pump oil stain on the bottom of the barrel and the liquid medicine of the concave part of the earth. Because the majority of pesticides have a certain corrosive action on the sprayer, so after the closure, in a timely manner to alkaline wash again, and then rinse with water. Especially the plastic sprayer  Bordeaux corrosive pesticide, it is best to use alkaline soak 1 to 2 hours. Attention should be paid to prevent rust. Who can remove the components should be removed clean. The pipe wall to oiling the spray rod, nozzle, to avoid damp rust.

Agricultural sprayer uses what physics knowledge

Agricultural sprayer is in the same liquid, high velocity, low pressure; velocity of small, high pressure. The fluid will automatically flow from the high pressure low pressure. In the low agricultural sprayers  flow through a three-way tube, flow to the high speed of the flow of air. The water is of high speed air to tear into droplets of a droplet (ideas out of the water, the tap water was just beginning to slow, gradually increasing the speed of; but later becomes a drop of a drop). These small water droplets sprayed out after a fog. High speed flow obstacles after splitting into small droplets of principle of second kinds of use is to put water into the tube backpack weed sprayer  by high velocity flow, high velocity flow obstacles after splitting into principle of small water droplets. The situation like a faucet after fingers blocked. Agricultural sprayer use of the structure, the cost is low. Centrifugal force principle of liquid thrown out of third is a high-speed rotating liquid atomizing disk will be thrown by centrifugal force, tear into small droplets similar to an umbrella rotation when the situation of ultrasonic Trigger Sprayer  principle of fourth is the principle of ultrasonic atomizer. Vibration can cause "waves" in the water, the ultrasonic vibration frequency is very high, so it's "wave" of the wavelength is very small, so its "spray" -- the small droplets are very small, these small water droplets into the mist.
