5 Medicine Box
5.1 The medicine box should have a clear capacity marking line. When the operator adds liquid to the medicine box, he can clearly see the liquid level: 5.2 The medicine box cover should not be accidentally opened or loosened. 5.3 Fill the backpack medicine box with clean water to the rated capacity, tighten the medicine box cover, and tilt the box at 45° to the vertical line in any direction. No liquid should leak out from the medicine box cover, vents, etc. ,5.4 The medicine box of the compression sprayer should be equipped with a safety protection device, and the venting pressure of the safety valve should meet the following requirements: maximum working pressure; not more than 1.2 times the maximum working pressure.
6 Liquid pump
6,1 The motorized liquid system should have a pressure regulating and unloading device. When the outlet stop valve is closed, the pressure increase shall not exceed 20% of the set pressure value. When unloading, the pump pressure should drop below 1MP. When reloading, the pressure should return to the original set pressure value. 6 .2 The motorized sprayer equipped with liquid sprayer shall be equipped with a pressure gauge or force gauge that can display the corresponding working pressure. 6.3 The exposed transmission device of the motorized liquid pump shall have the safety protection device in accordance with the provisions of GB10395.1. 7 Fan
7.1 The fan shall be free from damage, looseness and obvious deformation, and shall rotate smoothly and avoid abnormal noise. 7.2 The air inlet of the fan shall be equipped with a filter and a safety protection cover. 8 Pressure-bearing parts
8.1 The nozzle, spray rod, shut-off valve, pressure hose, hose connector, air chamber, pressure gauge (manometer) and other pressure-bearing parts shall have good pressure resistance and shall be maintained at 1.5 times the working pressure for 1 minute. No rupture and leakage are not allowed. 8.2 The nozzle shall have good performance under the standard working pressure, without obvious coarse stream and droplets; the deviation of the nozzle spray volume shall not exceed 10% of the calibrated spray volume, and the deviation of the spray angle shall not exceed 110° (the spray volume and spray angle shall be tested according to the methods specified in Appendix A and Appendix B).

Spray volume inspection method
A.1 Spray volume measurement method of the nozzle: On the nozzle test bench, measure the spray volume of the nozzle under the calibrated working pressure. Use a measuring cup or a measuring cup to collect the spray liquid, measure three times, take the average value, and then calculate the nozzle spray volume deviation based on the calibrated spray volume. A.2 Spray gun spray measurement method: measure under the calibrated working positive pressure, install the pressure gauge at the end of the spray gun, collect the spray liquid in a container and weigh it on the pound, calculate the spray volume of the spray gun, measure three times, and then calculate the spray volume deviation of the spray gun based on the rated spray volume. http://
Appendix B
(Normative Appendix)
Spray angle measurement method
NY1232-2006
Install the nozzle on the nozzle test bench, spray under the calibrated working pressure, and select one of the following three test methods to measure the spray B.1 Use a protractor to directly measure the angle of the outer edge of the mist flow. B.2 Use a photographic method to take a picture of the lower polar shadow of the mist flow, and then use a protractor to measure the spray angle on the photo. On the nozzle test bench, measure the spray temperature and nozzle height, and then calculate the spray angle. B.3
