Ultra-low-volume spray is a new skill that has been promoted in these years. It only needs to spray less than 330 ml of oil pesticide per acre to receive excellent control effect. Because the diameter of the droplet is very good.ãªâˆˆ æŒ¥ æŒ¥ æŒ¥ æŒ¥ æŒ¥ æŒ¥ æŒ¥ æŒ¥ æŒ¥ ( ( ( ( ( ( ( ( ( ( ( ( ( å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œ å†œEliminate the onset of various problems.
(1) Composition and operation principle: The ultra-low volume sprayer is a new type of spray machine with high work efficiency and control effect. It can be used for pest control of crops and fruit trees; it can also be used for storage of warehouses and greenhouses. The ultra-low volume sprayer is mainly composed of a fan, a liquid tank assembly and a spray component. The whole machine is fixed on the frame by four shock pads; the fuel tank, the medicine box and the handle are fixed on the frame. Because the machine uses air pressure Infusion principle; the power output shaft of the initiator rotates the fan impeller; the high-speed airflow occurs; the small airflow is used to cool the initiator; the other small airflow enters the liquid tank through the elbow booster tube to pressurize the liquid; Most of the airflow passes through the elbow and the nozzle to the spout to promote the high-speed transformation of the cage; the liquid medicine liquid flows into the high-speed rotating cage through the liquid medicine switch and the liquid-saving valve; and is smashed under the centrifugal force effect of the rotation of the rotating cage. Out; the high-speed airflow will send the droplets out of the spout; spray on the control target.
(2) Application and precautions:
(1) Preparation before use. Before using the ultra-low volume sprayer; should check whether the machine parts can be complete; whether the device can be correct; whether some of the connections can be firm and reliable; whether the transition can be sensitive and sensitive, to the launching machine When participating in the mixed oil of gasoline and engine oil; first, add water to the tank to test the spray; and investigate whether the tank and the pipeline through which the liquid flows are leaking; Whether it is normal, before use; also according to the prevention and control objectives; under the guidance of professional and skilled personnel to select the drug variety and dosage form; to be appropriate to the ultra-low volume spray. The amount of spray can be controlled by the saving valve.
(2) Operation in operation. When spraying pesticides; after the components of the standby device are running normally; the operator should walk first; then turn on the infusion switch; always keep the walking speed together; when stopping the spraying; first close the infusion switch Then you can shut down. When spraying; pay attention to the wind direction; should start from the downwind; the spray direction should be as common as the natural wind direction; do not allow the wind to spray. Use the side spray skills in the field spray; the nozzle can not be opposite Crops; but the crops must have a certain point of view; the size of the viewpoint depends on the natural wind speed; the principle is that when the wind speed is large; the viewpoint is large; the wind speed is small; the viewpoint is small. The spraying time should not be selected at the hot noon; natural When the wind is greater than grade 3; ultra-low-volume spray should not be implemented. Spraying should not be too long when spraying in warehouses, greenhouses, etc.; to avoid drug poisoning during personnel attack. When the sprayed liquid enters the bearing of the cage, there should be some; Remove the bearing; remove it with kerosene or gasoline; participate in the bearing chamber according to the requirements of the instructions to participate in the excess of molybdenum disulfide solid smoothing agent or calcium-based smooth grease smooth; then install the cage When spraying, do not touch the crops of the sprayer of the nozzle atomizer; to avoid damage to the cage, do not overfill the liquid in the tank; to prevent spillage; if there is any spillage, clean it immediately. After use; the remaining liquid in the liquid tank and the infusion tube should be released; the whole machine should be cleaned and cleaned, after the spraying operation is completed; before the preservation and storage; except that the remaining oil in the fuel tank and the liquid tank is cleaned; Also remove all; metal parts should be modified with anti-rust oil; then stored in a cool, ventilated place.
(3) Faults and methods of removal:
(1) The spray volume is reduced or not sprayed. During the inspection; if it is found that the position of the valve stem is not correct; the orientation of the spool can be good from the head, if it is blocked by the infusion switch; the infusion switch must be cleared, if it is a saving valve Blocking; the sanitary valve core should save the hole, if it is blocked by the shaft head outlet hole; the shaft head infusion hole should be removed, if the liquid tank is not pressurized or leaking; the pressurized joint can be reinstalled; The liquid tank cover is not tightened; the liquid tank cover should be tightened from the head.
(2) The fog particles are significantly coarse or the rotation speed of the cage is low. If it is found that the gasoline engine speed is not good; the gasoline engine should be adjusted or repaired. If the cage bearing is short of oil; the bearing should be removed and the smoothing agent should be added, if it is bearing wear; The new bearing should be replaced if the cage nylon mesh is blocked or broken; the mesh cover should be removed or replaced.
