Correct use and troubleshooting of mobile mist sprayer

First, the correct use of mobile mist sprayer, the main points are:

1. Before use, carefully inspect whether the connection parts are tight, whether there is oil leakage or water leakage, and add lubricant to each lubrication point. Before adding the drug solution, test it with clean water and confirm that there is no leakage before starting work.

2. Do not overfill the liquid when adding the liquid so as not to spill the liquid from the air outlet of the filter into the fan casing or the overflow, causing mechanical or personal accidents. After adding the liquid, the lid must be tightly closed.

3, spray, the nozzle should be tilted slightly downward, and swing left and right, the number of swings is generally a step to swing once as well, so you can use the liquid spray evenly. The spout should be kept at a distance of 30 to 40 cm from the crop to avoid damage to the crop due to wind.

4. As the fog particles of the mist eliminator are very fine, it is difficult to directly observe the spraying effect. Under normal circumstances, as long as the crop leaves are blown by the wind of the nozzle, the fog point is already reached. Do not compare the mist sprayer with the manual sprayer. The liquid concentration is 2 to 10 times higher than the manual sprayer. If it is the same as the manual sprayer, it will cause injury.

5, after the end of the operation, it is necessary to timely drain the residual liquid, and then use clean water to clean the liquid tank, liquid pump and pipeline, clean water should be removed after cleaning, dry, to prevent corrosion parts.

Second, there are some faults in the use of the mobile mist sprayer. The common faults and their elimination methods are as follows:

1, carburetor leakage. When the gasoline engine is stopped, if the main spray hole is found to be leaking oil, the reason may be that the balance lever of the carburetor is adjusted too high or the needle valve is dirty. Clean the needle valve seat and lower the balance lever properly until Do not leak oil.

2, spark plugs do not flash over. In the case of a high-voltage line with a normal flashover, the spark plug should be removed first to see if there is coke, whether the electrode is wet or if the gap is normal. According to the situation, remove coke or dry, and adjust the clearance to about 0.6-0.7 mm. If spark plug insulation damage or electrode burnout is found, replace it. If the spark plugs are all normal, it may be caused by the damage of the magneto motor and should be removed for repair or replacement.

3, reduce the amount of spray or spray can not be. In the case of engine operation, check whether the air inlet valve is open, whether the cover of the medicine tank is leaking or whether the rubber gasket is damaged; secondly, check whether the air inlet pipe in the medicine box is twisted, the nozzle, the switch, the regulating valve and the filter ventilation. If the hole is blocked, it should be cleaned and blocked when blocked. If the spray cannot be sprayed vertically, it may be caused by the nozzle being raised too high. The nozzle should be lowered to maintain an angle of 60 to 70 degrees with the ground.

4, the liquid into the fan. Check the inlet apron first. If it has been damaged or lost its elasticity, it must be replaced with a new one. If the intake apron and the air plug have a large clearance, a layer of tape may be wrapped around the air intake plug to increase the tightness of the intake plug and the apron. If it is caused by the falling off of the transparent plastic tube of the air inlet plug and the filter, it needs to be reinstalled.

5, hand switch leak. Check whether the switch cover is screwed tightly. If it is tightened, check whether the sealing rubber ring on the switch core is worn and replaced when it has worn out. Look at whether or not the contact surface between the switch cone and the housing is sealed. If the seal is poor, it needs to be ground to make it close.
