What are the inspection points of self-propelled spray before operation? Let's take a look with the editor today.

(1) If the airtightness of the greenhouse is good, the prevention and control effect is good. The damaged parts of the plastic film, the gaps between the ventilation fan and the inlet and outlet must be repaired and pasted before applying the medicine. Especially for the gaps in the skylight, around the lower part of the greenhouse, and the ventilation fan valve, do not miss repairs.

(2) Air compressor part: Plug in the power cord and the indicator light will light up (red). At this point, all switches are in the off state.

(3) Connect the fan power cord and air hose to the socket and air outlet of the air compressor, especially the plug of the connecting cable. After inserting it, turn it to the right and lock it tightly to prevent it from falling off due to vibration during machine operation.

(4) The connection between the fan motor and the connecting wire adopts waterproof plugs and sockets, which should be firmly inserted and locked by turning to the right. The air hose should also be firmly connected.

(5) The commonly used air pressure is between 100 kPa and 160 kPa (the air pressure should not exceed 300 kPa). When the pointer swings too much, tighten the gauge valve to protect the pressure gauge. When the pressure is low, check if there is any air leakage at each connection, if the nozzle cap is loose, and if the lower discharge port of the frame is open. When the pressure is too high, check if the nozzle and air hose are blocked (a slight increase is not a fault).

(6) The spraying amount of this machine is generally around 45 milliliters per minute of pesticides, and too little or too much spraying can affect the prevention and control effect. Before use, spray with clean water at a rate of 50 milliliters per minute. Turn the nozzle cap all the way back to the center mark, and the spraying amount is exactly right. If the screwing depth exceeds the center position, the spraying amount will increase, and if it returns, the spraying amount will decrease. The knurling change for each grid is 2.5 milliliters/minute to 3.0 milliliters/minute.
