How to operate can extend the life of electric sprayer

The electric 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 it to extend the service life of the sprayer.

First of all, during the next formal use, 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 the sprayer is used, clean the barrel, hose, spray rod and other parts of the electric sprayer first, and pay special attention to removing the grease on the pump and the mud on the recessed part of the liquid tank bottom. 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 with more corrosive pesticides such as Bordeaux mixture, it is better to soak in alkaline water for 1-2 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.

In addition, the core components of the electric sprayer are the electric sprayer diaphragm 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 prepare the medicine. When adding water, it must be filtered with a small filter to prevent clogging.
