In the arsenal of gardeners and summer residents, the sprayer occupies one of the main places as a tool for caring for plants, shrubs and trees. This sprayer is used outdoors, in greenhouses and agricultural fields. And in each case, the conditions for using a garden sprayer dictate their requirements for choosing a particular model.
Principal arrangement of the tool
Designs can be different, but they all have three main parts - a container for containing a useful spray mixture, retention elements and tips for jet release. As for the capacity, it can be represented by vascular devices, volumetric tanks and even transportable tanks. A control lever with a tip is brought to the content. The user makes an effort, as a result of which the active mixture is sprayed.
The principle of operation may be different - it depends on the pumping mechanism. The simplest hand-held garden sprayers havean eyeliner with a thin hose through which the liquid is pumped into the spray gun and released in the form of tiny drops. But even this simple system provides the ability to adjust jet modes from continuous to drip spray.
Features of pump models
In the family of non-power assisted hand sprayers, these models can be considered the most advanced. By itself, the pump mechanism is a pump that works due to manual effort. Mechanical garden sprayers use forced air and rising pressure to atomize the contents of the container through the nozzle with a pump.
Unlike conventional manual models of sprayers, which also work from the physical effort of the user, this case does not require constant pressing of the lever or trigger. It is necessary to initially pump the tank through the pump, after which the garden sprayer will work autonomously for some time.
Knapsack sprayers
The peculiarity of this tool is not in the principle of operation, but in the structural organization of the operator's interaction with the spraying mechanism and related equipment. For ease of wearing, the tank is provided with shoulder straps. The flattened shape of the container itself is comfortable for this way of carrying, which makes the work more productive and efficient. The very same mechanism for pumping and supplying liquid can be different. But since the knapsack gardenThe sprayer with its design makes an impressive performance reserve with the expectation of long-term operation sessions, developers more often provide such models with power plants. However, devices with engines deserve special attention.
Gasoline and battery sprayers
Most liquid fuel models are equipped with a conventional hand operated starter. The next level is an automated garden sprayer with a powerful two-stroke engine. For 4-hour continuous operation, it is enough to equip with a 2.5 kW installation. The consumption of the working mixture in this case will be about 5 l / min, which is 10 times higher than the performance of mechanical sprayers.
Gasoline models also have significant drawbacks. Firstly, such devices are heavy precisely because of the heavy engine, and secondly, harmful exhausts adversely affect the environmental situation in the spray zone. These shortcomings are deprived of a battery garden sprayer, the power elements of which provide operability for 2 hours. The fluid consumption, however, is small compared to gasoline models and is only 0.3-0.5 l / min. But the lightweight design allows you to add volume to the tank.
Sprayer Specifications
The volume of the tank will be the starting point in choosing any garden sprayer. The entry level is represented by manual models with 1-2 liter tanks. These are compactconvenient devices with which you can handle small bushes and house flowers in pots with one hand. To care for fruit and vegetable plants in the garden, you will need a more productive unit with a capacity of up to 10-15 liters. It can be both a pump-action and battery-powered garden sprayer with a wide range of options for adjusting the chemical supply parameters. The most voluminous are backpack sprayers with a gasoline engine. Such models are supplied with tanks with a capacity of up to 25 liters.
Another important characteristic is the material of the device construction. As a rule, garden hand sprayers are made of high-strength plastics that are resistant to chemically aggressive substances. The best solution would be ABS plastic, which is not destroyed in close contact with calcium, silicon and magnesium, and also resists direct sunlight and high temperatures. It is better to refuse metal devices immediately, as they are impractical and heavy.
What else to consider when choosing?
In addition to technical and operational parameters, it is important to evaluate the conditions of use of the device in terms of the need for support with auxiliary devices. Sprayer kits can be supplemented with various accessories that increase the convenience and efficiency of work. For example, it is recommended to equip a conventional hand sprayer with hoses and nozzles of different formats with an ergonomic control lever. For a pump model, it will not be superfluous to provide a holding fixture and a spray bar. ToIn a word, a telescopic garden sprayer is optimally suited for working with trees, in which the hose has a retractable design up to 5-7 m long. It is recommended that users of battery models also buy special accessories. In this case, you may need a charger and an additional battery, which will double the sprayer's run time.
Conclusion
Much as a sprayer depends on the manufacturer. The owners themselves note that models from the initial link from reputable brands sometimes seriously outperform multifunctional developments from little-known Chinese companies in quality. So, the best garden sprayers are produced by specialized garden tool manufacturers like Gardena, ECHO, Champion, Stihl and Solo. Worthy models can also be found in universal companies covering various segments of professional and household appliances. These include the brands Bosch, Makita, Karcher, etc. Of course, such products are not cheap, so it will not be out of place to look into the range of more affordable domestic products. In this niche, Caliber sprayers, a wide model range Zhuk, Izumrud and Kurs devices deserve attention.
