Sprayer principle

In fact, the water mist droplets. There are four conventional sprayer.
     One kind using Bernoulli's principle. Bernoulli's principle says that in the same liquid, the velocity, small pressure; small flow rate, pressure and powerful. Fluid will automatically flow from the high pressure low pressure. In adopting the trigeminal tube (Figure not drawn specifically, his insight), low-flow water to the high-speed flow of air. Water was torn a small high-speed air a small drop (imagine tap water flowing, the beginning is slow, the water column; but then gradually increasing the speed, it becomes a drop by drop). These droplets erupted since become fog.
     The second use is caused by the pressure into the tubule after high-speed flow, high speed flow encounter obstacles fragmented into small droplets. Situations like the faucet Rolling make big block with finger. Household sprayer and more with this structure and low cost.
     The third is to take charge of water (water is a dielectric), the use of the same charge repel each other into the water droplets. This method is a small particle droplets. The same principle is also used for automotive paint.
     The fourth is the ultrasonic atomization. Vibration can cause the water "spray", the frequency of the ultrasonic vibration is very high, so that the "wave" of the wavelength is small, so it's "spray" - is very small droplets, these droplets become fog. Hospital treatment of respiratory spray jets machine is to use ultrasonic atomization.

Using the principle of fruit tree sprayers

Fruit tree sprayers nozzle can rotate between distribution configuration selected including spray and flow. Nozzle and / or fruit tree sprayers, can be adapted to provide fruit tree sprayers  through charts and / or in other operating conditions the way. In some embodiments, the nozzle through electronic components merge suitable adapted to provide detection and indication function and / or electronic control functions, such as adjustable rheostat output pressure control. For example, backpack pressure sprayer  and display the distribution of pressure, residual amount can spray solution. Fruit tree sprayers can also be adapted to provide a visual signal condition, such as through the provision of lighting, appropriate light source such as LED to prompt the remaining battery capacity. It can also be backpack weed sprayers  to provide other types of signals to users or potential buyers, such as visual, tactile, auditory.

The principle of work and the pressure of knowledge of backpack garden sprayers

Because backpack garden sprayers air pressure balance, spewing out of the fog point from the beginning to the end, to maintain steady state of fine and uniform. And labor, improve efficiency: the product before use, only self cylinder or pneumatic backpack garden sprayers  and a gas can be on hundreds of acres of farm and sideline crops can spray, such as not artificially deflate, pressure can be kept in the machine, before use, if found insufficient air pressure, can use bicycle pump air to. When in use, when the pressure, liquid adding to (i.e., the yellow line part), a garden hand sprayers  capacity up to 12 kg. Spraying period: such as spray a fine mist, a barrel only 9 minutes; such as spray mist of a barrel of crude, only 6 ~ 7 minutes. Therefore, to reduce labor strength of more than 3 times higher than the handle lifting pressure sprayer, work efficiency can be increased more than 3 times. Because the product adopts the water pressure device to the method of liner water injection (a barrel of water about pressure about 55 times), each pressure once, backpack garden sprayers water in the garden sprayers  is to roll, the agent and water in the barrel is fully stirred and dissolved, thus make the sprayed liquid is very uniform, until the end of the spraying when the barrel, also no residual medicine liquid, therefore, it does not form any by liquid medicine is too strong and cause burn seedlings and pests immortal phenomenon caused by the liquid medicine is too light.

What is the principle of hand pump sprayers

Hand pump sprayers is to work according to the relationship between flow rate and pressure of gas. When the hand sprayer piston, the velocity of air flow into the upper Straw liquid in hand pump sprayers  up, reduce the pressure, and the liquid medicine bottle is equal to the air pressure above the outside atmospheric pressure, thus makes the air pressure is greater than the pressure above the liquid backpack pressure sprayers  Straw mouth, hand pump sprayers at atmospheric pressure under, put the medicine on the hydraulic Straw, then from the front end of the ejection of pelvic.

Fruit tree sprayers parts are introduced

Fruit tree sprayers is an appropriately coupled to liquid distributor on the container. The dispenser fruit tree sprayers  liquid spray head, an energy source and a fluid path. The liquid nozzle comprises a liquid pump, start the motor, liquid pump control motor triggers, and pump discharge end in fluid communication with the nozzle. The backpack weed sprayer  is communicated with an air inlet end part of the fruit tree sprayers liquid path and the pump, the other part in the container. In one embodiment, the liquid pump is a peristaltic pump. Fruit tree sprayers can further include: valve, which has used to control fluid through the diaphragm valve, the plastic sprayer  has an open position and a closed position; and vacuum pressure, which at one end of the valve, drive can overcome the elements, thus the diaphragm moves to an open position.

The medication method using backpack garden sprayers

A, accurate medication A variety of pesticides have residual period certain, invalid. Control frequency according to the occurrence of pests and diseases and insect pests of medicament backpack garden sprayers  period to decide, can receive the good effect. Wind, rain, fog, at noon when the high temperature not spraying, spraying backpack garden sprayers in the morning 10 points before and after 4 p.m.. After spraying rain, after the rain to fill spray. During the spraying should be uniform, fog shoulds not be too big, the spraying of thoughtful, let plants and leaves both sides fully with the medicine, and do not re spraying no leakage, ensure the spraying quality. Two, rotation of medication A region long continuous use of a single pesticide, easy to produce drug resistance, especially in backpack pressure sprayers  insecticides, fungicides, control effect of continuous use will fall sharply. Use backpack garden sprayers for rotation of different pesticides, is delaying pest resistance to produce effective method. Six, mixed use The compound pesticide reasonable mix, can improve the control effect, expand the control object, delaying resistance, labor-saving and time-saving, give full play to the role of backpack garden sprayers pesticide formulation. Although the complex mix of pesticides are of great benefit, but must not be backpack pressure sprayer  combination, because some pesticides can mix, others can not mix. To fully understand the nature and the possibility of pesticide between mixed before use. Pesticide on should not be mixed to use, each time after spraying, to timely cleaning prandi electric sprayer.

Simple hand pump sprayers using the method

Hand pump sprayers during the spraying head is always maintained at the height of 1 meters high on the plant. Because this kind of spray nozzle saves liquid, liquid medicine flows out by hand pump sprayers  in the bottle down time. Therefore, when the motor is not open, the bottle should be below, head of the above. During the spraying, should first start the motor, then change the bottle and head position, so that the bottle at the top, the bottle mouth downward, the bottle body is perpendicular to the ground, the liquid that can flow automatically. During the hand pump pressure sprayers , started by the downwind direction, walking routes and should be spaced a certain distance, namely the spray range. The size of the spray range should be based on the size of the wind speed and flexibility. Speed hours, spraying range should also be smaller, otherwise should be larger, generally 3 to 3.5 meters is appropriate. Each time in the morning, low pressure sprayer  or the best selection of cloudy, avoid sun exposure. Hand pump sprayers is best to use Systemics, fumigant or stomach poison. The dosage of 50 grams per acre general. For the amount of water available, "equivalent method".
