The electric super-capacity sprayer is popular with more and more vegetable farmers because of its convenient use and high work efficiency. It has become the main tool for pest control in the greenhouse. However, electric sprayers are relatively "precious". Once they are improperly operated and maintained in time, they are prone to malfunctions. How to maintain the sprayer in order to extend the service life of the sprayer, the reporter specially interviewed Manager Han, who is engaged in sprayer sales, and he suggested that vegetable farmers should do the following.
First of all, when using it for the first time, check whether the connections are leaking. When using, install the clean water test spray first, and then install the medicine. When adding medicine, add the medicine first and then add water, and the liquid level of the medicine 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, clean the liquid medicine barrel, hose, spray rod and other parts first, and pay special attention to removing the grease on the pump and the dirt on the bottom recess of the liquid medicine barrel. Because most pesticides have a certain corrosive effect on the sprayer, after stopping it, it should be washed with alkaline water in time, and then rinsed with clean water. Especially after spraying Bordeaux mixture and other corrosive pesticides, it is best to soak in alkaline water for 12 hours. Take care to prevent rust. All parts that can be disassembled must be removed and cleaned. The inner pipe wall of the spray rod and nozzle should be painted with engine oil to avoid damp and rust.
If the sprayer is not to be used for a short period of time, the main parts should be cleaned, wiped dry and installed, and stored in a cool and dry place. If it is not used for a long time, grease all metal parts to prevent rust.
In addition, the core components of the electric sprayer are the water pump and the 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 prepare the medicine. When adding water, it must be filtered with a small filter to prevent clogging.
Also, a special reminder to vegetable farmers: After the sprayer is deactivated, its battery should be fully charged and placed in a dry place in the shade, and charged once every one or two months. If the storage time becomes shorter, add distilled water to it in time.
