Sprayer garden is a kind of tool designed to spray fertilizers, agents from parasites and plant diseases. To date, the market presents a large number of sprayers, different in price, characteristics, appearance, methods of spraying. 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 a garden sprayer should handle. In principle, sprayers are conditionally divided into several groups, which most fully reflect the purpose and location of the apparatus: motor-sprayers, electric or battery, and also manual. The choice of this or that device, first of all, depends on the area of the surface being treated.
Sprayer garden with a gasoline engine is able to spray the working fluid to 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-garden farms.
Approximately the same properties have an electric sprayer garden. 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, more convenient, more compact and is the most affordable of all presented on 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 one side a hose is attached, which is lowered into a container with a chemical solution, 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 type of hand sprayer was the garden knapsack sprayer. It is much more convenient, since the liquid bottle 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.
