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.

Using the principle of back sprayers

The fog is actually water droplet. The existing back sprayers has four. A is the Bernoulli principle. The principle of Bernoulli said in the same liquid, high velocity, low pressure; back sprayers  of small, high pressure. The fluid will automatically flow from the high pressure low pressure. When in through a three-way tube (specific diagrams can be drawn, yourself), back sprayers low speed 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 backpack pressure sprayer  the speed of; but later becomes a drop of a drop). These small water droplets sprayed out after a fog. The second use is put water into the tubule caused by high velocity flow, high velocity flow obstacles after splitting into small drops of water. As the tap after rolling make big fingers blocked. Home of the back sprayers 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 by the same charge. This method is very small droplet. The same principle is also used to give the car paint. The fourth kind is ultrasonic backpack garden sprayer . Back sprayers 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. The hospital throat spray machine for treating respiratory disease is the use of ultrasonic atomization.

After the agricultural sprayer control flowers, turf advantage and use method

After the agricultural sprayer spray in prevention and treatment of flowers, grass and crop pests and diseases, compared with the sprayer used, with fast, efficient, convenient, save cost etc.. Specific performance:
A, use less water
After the  agricultural sprayers  is used in the pesticide solution, or only after dilution of very low times, so it does not need a large amount of water.
Two, less dosage
Spraying liquid per 100 grams, rather than tens of kilograms, or even hundreds of kilograms. Therefore, when in use, can greatly reduce the labor intensity, saves labor.
Three, droplet distribution
After the agricultural sprayer is not the solution directly spray on plants, but with the wind so that the diameter is only tens of microns droplet dispersion drift, then around plants "micro flow" effect, the droplet distribution in leaf and the whole plant positive, negative and side. So, than the large amount of water diluted reagent for higher rate of killing pests, especially has developed resistance to pests to some, better. Because of the pesticide liquid killing function than diluted with water several times higher than even a few times.
Four, easy to use
After the agricultural garden sprayers backpack  nose always keep in higher plant height of about 1 meters. Because this kind of spray nozzle saves liquid, liquid outflow to the bottle down. Therefore, when the motor is not open, the bottle should be below the head at the top. During the spraying, should first start the motor, then change the bottle and the position of the head, the bottle at the top, bottle mouth downward, the bottle body is perpendicular to the ground, the medicine liquid can flow automatically.
During the spraying, started by the downwind direction, the route to be separated with a certain distance, the spraying range. The size of back sprayers  should be based on the wind speed and flexibility. Wind hours, spraying range should also be smaller, otherwise should be larger, generally 3 to 3.5 meters is appropriate. Each time in the morning, afternoon or preferably shade, avoid sun exposure. Ultra low volume spraying the best use of systemic insecticides, fumigants or stomach poison. General dosage per 50 grams. For the amount of water available, "equivalent method"

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 .
