Sprayer garden: varieties, the principle of work
Sprayer garden is a kind ofa tool designed for spraying fertilizers, parasite and plant diseases. To date, a large number of sprayers are available on the market, different in price, characteristics, appearance, spraying methods. But in spite of such a variety, it is quite simple to choose a particular device, it is only important to determine the tasks that the garden sprayer should handle. In principle, sprayers are conventionally divided into several groups, which most fully reflect the purpose and location of the apparatus: motor-sprayers, electric or battery, as well as manual ones. The choice of this or that device, first of all, depends on the area of the surface being treated.
Sprayer garden with gasoline engineis able to spray the working fluid over large areas or to a large height, it is perfectly suitable for spraying trees, because the jet can reach 10 meters depending on the capacity of the unit. However, the size and price make use of this type justified only in large garden and vegetable farms.
About the same properties possesseselectric garden sprayer. It is smaller than gasoline, but more convenient than manual. The principle of operation does not differ from other devices - a solution of chemicals or fertilizers is sprayed under the pressure of a stream of air, which is created by a small compressor. The tool of this type was also widely used and used in construction and repair as a spray paint and varnish materials.
A garden sprayer of a manual type is lighter,is more convenient, is more compact and is the most accessible of all presented in the market. The principle of its operation is simple: in a container with a liquid, pressure is created, the spraying occurs from a small nozzle. The most primitive garden sprayer consists of two tubes resembling a bicycle pump, to which, on the one hand, a hose is attached to a container with a solution of a chemical, and on the other side is a spray head.
However, this kind is not very convenient to use.The next type of hand sprayer is more popular due to the fact that the working pressure is created in the liquid container with the same "pump", after which it is only necessary to press the valve to apply the solution under pressure to the sprayer. This species has received the widest application among summer residents. The volumes of cylinders vary from one to ten liters, and the presence of a telescopic tube allows processing of low trees or low plants even in places where it is usually difficult to reach.
A more perfect kind of hand sprayerbecame sprayer garden knapsack. It is much more convenient, since the liquid container is located behind the belts and allows long processing of large areas with the minimum possible load. Plus, on such devices, special pumps are installed, which can create working pressure directly during operation, without interruption.
