When fruit trees and crops are sprayed to prevent pests and diseases, medicinal liquids are sprayed to spray liquids with fine droplets, covering a large area, and the chances of contact between liquid particles and diseases and insect pests are significantly increased. Labor and medicine are saved and the efficiency is high, and the control effect and economy can be improved. benefit. The key to the prevention and control of medical devices is to master the application technology of medical devices. Now, the structural characteristics, technical points, and troubleshooting methods of the 0.5-type single plunger sprayer commonly used in the market are described as follows: First, the structural characteristics The plunger copper rod is directly used as the pressurizing part, and the metal encapsulation liquid and the pressure chamber are in the same chamber, and the sealing property is excellent. Automatically establish the pulse liquid pressure regulator, without a fixed drug tank or liquid barrel, the general performance is good. Copper plunger rod for wear resistance and corrosion resistance, working pressure up to 10 kg / square centimeter or more, extended infusion tube with double operation, to adapt to mature fruit trees spraying liquid, liquid droplet diameter 75 ~ 250 microns . Second, the technical points 1. The plunger copper rod directly pressurizes the liquid and generates high pressure. When using the infusion tube, the pressure should be more than 10 kg/cm2. When spraying, the length of the infusion tube should be 10 meters, and the pressure loss of the pipeline is too long. , so that the atomization quality of the liquid drops. 2. The plunger copper rod is a reciprocating linear motion pressurizing member. The rubber seal is used to seal the running rail. The force should be used smoothly to reduce the damage of the rubber ring. 3. When the rigid suction plate directly contacts with the base of the liquid barrel when pressurizing, and the force area is small, it is necessary to pad one board under the suction plate to reduce the damage of the liquid barrel. Third, troubleshooting 1. If there is leakage at the plunger rod and seal ring during pressurization, the adjustment nut should be screwed in 1/2 and lubricated with a little grease to increase the seal. 2. When the pressure of the Chinese medicine liquid under pressure is low or it cannot be fogged, it is because the bottom liquid inlet valve is not closed and should be removed or replaced.
