The working process is as follows: turn on the power supply of the water pump, the water pump will pump the liquid medicine in the medicine box into the nozzle through the pressure regulating valve, turn on the electrostatic power supply at the same time, and the charged droplets will be ejected. Figure 5 frontiersin Figure 5. Schematic diagram of electrostatic spray system. 3.2. Selection of main devices Polyethylene is a thermoplastic resin prepared by polymerization of ethylene. In industry, it also includes ethylene and a small amount of α-Copolymers of olefins.
The main purpose of the medicine box is to store the medicine liquid, which must have good corrosion resistance. In this study, polyethylene material is selected to make Spain phone number list the medicine box (with a capacity of 300 L), which can achieve the purpose of high temperature resistance and corrosion resistance. The main purpose of the water pump is to provide water pressure. The DC diaphragm water pump with 12 V input power supply and 0.6 MPa output pressure is selected. The main purpose of the pressure gauge is to provide real-time water pressure display.
The pressure gauge with a range of 0-1 MPa is selected according to the. The main purpose of high voltage electrostatic power supply is to transform the input 12 V DC power to more than 10 kV and then output it to the electrostatic nozzle. In order to ensure the charging effect, 0–20 kv adjustable electrostatic power supply is selected. The main purpose of DC power supply is to convert 220 V AC to 12 V DC. Water supply pump and electrostatic power supply are used. In order to ensure stable power supply, 2,000 W switching power supply is selected. Induction electrostatic nozzle is selected for electrostatic nozzle.
