e loopholes in it, so they do everything possible to use fake and shoddy methods to add a cheap high-voltage generator to the ordinary electric sprayer and pretend to be static electricity. The sprayer has been ostentatious in the market, deceiving farmers and consumers with a price several times higher than that of the electric sprayer, and fooling the relevant departments, in order to deceive high profits and government subsidies for agricultural machinery.

So, how can we distinguish the true and false from the pros and cons of an electrostatic sprayer manufacturer? The author introduces a simple method here: as long as you look at the three index conditions, which are true and which are false, which are better and which are worse, you can quickly distinguish them.

We take a single-nozzle knapsack electric electrostatic sprayer with a capacity of 16 liters and an electric diaphragm pump with a pressure of 0.15-0.4 MPa as the spraying power as an example to check the index conditions it should have:

One is to check the flow indicator of the sprayer. One of the advantages of electrostatic sprayer is that it can save about 90% of water. Therefore, its normal flow rate should be 5-15 liters per hour, generally not more than 20 liters. Under normal circumstances, a bucket of 16 liters of water can spray an area of about ten acres. The flow rate of ordinary electric sprayers is as high as 60-80 liters per hour, and it may consume 48 liters of water to spray one mu of land. If you find that a bucket of water can be sprayed in about 10 minutes, then you can basically assume that this is just an ordinary electric sprayer.

The second is to check the electrostatic adsorption effect index after spraying. The unique and strange effect of electrostatic sprayer is that it has a significant electrostatic environmental protection adsorption effect. That is to say, when the nozzle is sprayed on the leaves of the planting branches, not only more droplets can be attached to the leaves, but also the reverse side of the leaves will magically absorb more droplets, so even if the pests hide in the leaves Behind, it can also be effectively killed. For an electrostatic sprayer with good effect, the electrostatic adsorption effect index of the sprayed droplets should be about 100 to 50, that is, if there are 100 droplets on the front of the blade, then the number of droplets adsorbed on the back should be 50 points. About 30 points lower, otherwise, it will seriously affect the due killing effect. If there is no adsorption on the reverse side or there are only about 10 points of adsorption, it means that this is just a fake machine.

The third is to check the pesticide saving index of machine operation. After a large number of scientific research and field practical application tests, the unanimously recognized effect standard obtained from all aspects is: the application of electrostatic spray can save 30-50% of the chemical dosage. That is to say, the use of electrostatic sprayer, in the case of saving 30-50% of chemical agents, its killing effect is still better than that of ordinary sprayers that do not save pesticides. If an electrostatic sprayer cannot use less pesticides in practical applications, or if the proportion of pesticides reduced will also affect the killing effect, then it can be considered that it is only a fake machine.
