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".

Fruit tree sprayers relieves poisoning of sorrow

An ordinary farmers, now is the season to cotton spraying pesticides, pesticide skin allergy Zhou Xian told reporters, each to this time, he was committed shocking. That kind of ache to itch fruit tree sprayers  again taste, it is hard, he has been pondering the pesticide poisoning problem. After repeated experiments for two years, he developed a fruit tree sprayers: do people medicine separation, effectively solves the problem of pesticide poisoning. Although the pesticide sprayer ugly in backpack garden sprayer  appearance, but a lot of features: not only the four nozzle direction can be adjusted arbitrarily, also can adjust the height. The key is the people back instead of wheels, a drug to both light and fast. This pesticide spraying machine, an acre of land only ten minutes, greatly improving the efficiency. Since he invented pesticide sprayer spraying, has nearly thousand Chinese acres of hand pump pressure sprayer  for the villagers around fruit tree sprayers, has been the recognition and praise. At present, he applied for a national patent for pesticide spraying machine, hope to be able to mass production, for the people to bring more tangible benefits.

Backpack garden sprayers after cleaning and not general idea

Backpack garden sprayers should be cleaned immediately in the spray treatment, especially the use of highly toxic pesticides and herbicides, it will immediately machine barrel clean, backpack garden sprayers  produce harm to crops or vegetables will. Herbicide treatment long leaf plants, treatment of broadleaf plant, Contraceptive during use if not clean, alternative easily hurt by different types of plants. Therefore, backpack garden sprayers, spray machine after cleaning and careless. The cleaning method: 1, herbicide (1) Shimizu Shirai: herbicides such as star (Ben Huanglong), maize herbicide acetochlor and atrazine mixture, such as soybean, peanut, herbicides such as haloxyfop, paddy herbicides as hoe, Bentazon, in after, immediately wash with water bucket and parts number, er After the garden hand sprayers  filled with backpack garden sprayers for 2-24 hours, then washed 2-3 times, can be assured use. (2) slurry cleaning: for G without a trace (commonly known as sweep away the light) in soil can be passivated, lose principle herbicidal activity, therefore after herbicide g without a trace, if immediately with garden sprayers backpack  cleaning several times, then rinse. (3) the ferrous sulfate wash: herbicide, only 2, the most difficult cleaning of 4-D butyl ester. In spray the herbicide, need 0.5 ferrous sulphate solution fully wash. 2, pesticide (1) general pesticide use, repeated washing with water, upside down to dry.
