The electric super-large-capacity sprayer is more and more popular among vegetable farmers because of its convenient use and high work efficiency, and it has become the main thing for preventing diseases and insect pests in the greenhouse. However, the electric sprayer is relatively "precious". Once the operation is improper in use and the maintenance is not timely, it is easy to malfunction. How to maintain, so as to extend the service life of the sprayer, the reporter specifically interviewed the manager Han who is engaged in the sales of the sprayer. He suggested that the vegetable farmers should do the following.

First of all, in formal use, check whether each connection leaks. When in use, first install a test spray of clean water, and then install the medicine. When adding medicine, add the medicine first and then add water. The liquid level of the medicine liquid should not exceed the safe water level. Before spraying, turn on the electric sprayer in advance to increase the air pressure in the barrel to the working pressure to ensure smooth spraying.

Secondly, after using the sprayer, first clean the liquid barrel, hose, spray bar and other parts, and pay special attention to shoveling the grease on the pump and the mud in the bottom of the liquid barrel. Because most pesticides have a certain corrosive effect on sprayers, after use, they should be washed with alkaline water in time, and then rinsed with clean water. Especially after spraying highly corrosive pesticides such as Bordeaux mixture, it should be soaked in alkaline water for 1? 2 hours. Pay attention to avoid rust.

All parts that can be disassembled must be removed and washed clean. The inner pipe wall of the spray bar and spray head should be altered with engine oil to avoid moisture and rust. If the sprayer is not to be used in a short period of time, the main parts should be cleaned, wiped dry and stored in a cool and dry place. If it is not necessary for a long time, grease all metal parts to avoid rust.

In addition,Electric sprayerThe core components are water pump and battery. Although there are several types of pumps on the market, these pumps are afraid of clogging. Therefore, it is necessary to use clean water to flush the medicine. When adding water, it must be filtered with a small filter to avoid blockage.

In addition, a special reminder to vegetable farmers: After the sprayer is deactivated, its battery should be fully charged and placed in a dry and shaded place, and it should be charged every one or two months. If the storage time becomes shorter, add distilled water in time.
