What features should a suitable sprayer have?
A sprayer is often used to spray various materials such as pre-emergent and post-emergent herbicides, insecticides or pesticides and fungicides. It may be necessary to change the nozzles, which can affect the spray volume and system pressure. The type and size of the sprayer pump required is determined by the type of poison, the recommended pressure and the amount of spray from the nozzle. It is necessary to deliver the used materials to the nozzles. A sprayer pump must have a capacity equivalent to at least 25% more than the maximum volume required for the nozzles.
The main components of a sprayer
Whether it is a sprayer behind a tractor or a car (self-driving), both are made for the same purpose of spraying pesticides, fungicides and herbicides. Most sprayers are built with the following basic components: agitator, valve, hose, pump, motor, strainer, and tank. It's a good idea to become familiar with these parts, as it makes troubleshooting problems much easier.
Since many chemicals used on crops can be corrosive, choosing A tank or tanker with corrosion-resistant materials such as stainless steel, fiberglass, or polyethylene plastic is also important. Even if you do not use these devices, it is important to keep the tank clean and free of dust to protect the tank from rust and other contaminants that can damage the pump and hoses. .
sprayer mixer; To combine toxins with water and prevent precipitation
The agitator of the foliar spraying tank mixes the materials to be sprayed in the tank homogeneously (that is, as a uniform composition) and keeps the chemicals in suspension instead of settling on the bottom of the tank. . For different types of chemicals used, different mixers are needed.
Wetable powders (Wetable powders (W to WP) are small solid particles that contain a type of dry carrier, herbicide and dispersing agents) need a They have a strong stirrer, so you should use a separate stirrer, either hydraulic or mechanical. An adjustable agitator can minimize foaming from certain chemicals because the volume of the tank is reduced.
In general, sprayer pumps are classified into four types:
- Centrifugal pumps or centrifugal pumps
- Rotating or rotary pumps
- Piston pumps
- Diaphragm pumps
Differences The subtleties of different styles of sprayer pumps are mainly related to the amount of water displacement and the amount of material delivered inside the sprayer. More important than the style itself, your pumps should be resistant to pesticide corrosion, and the materials used in the pump housing and felt bowl should be resistant to chemicals, including organic solvents. This issue will not be a problem for new and updated equipment, but as the life of the sprayer increases, or if you intend to buy second-hand equipment, check the pump carefully.
Lance sprayer
A sprayer lance is very useful for foliar spraying in the garden. Try to buy a quality lance, with the right length and chemical resistant hose. A high-quality spraying lance performs the action of cutting and connecting the foliar spraying well and quickly, which saves on expensive chemicals. The sprayer lance must be strong to withstand wear and high pressure.
sprayer hose
Smaller-than-usual hoses and fittings can severely reduce the capacity of any sprayer pump. The diameter of the suction hose or hose must be at least the size of the pump inlet. Before spraying, all hoses and fittings should be checked for cracks or leaks when under pressure.
Avoid branches if possible as this will A leak or failure occurs in your foliar spraying system. A sprayer does not work without proper hoses that connect to the tanker or tank, pump and nozzles because hoses are the main components of the spraying system.
