The Tank
It
acts as a medium for strong spraying materials. This can be made of
steel, satisfactory is properly galvanized or otherwise treated after
fabrication to prevent erosion. Plastic materials are also used on
account of freedom from corrosion and ease of molding into smooth shapes
which avoid the difficulty of agitating in recesses and sharp corners.
Rand
–bottom tanks are best suited to use of a horizontal mechanical gaiter
however, hydraulic agitation is preferred by many manufacture good
hydraulic mixing is achieved if a tank with a curved bottom s used, and
the pipe runs horizontally near the bottom
Pump
This is a device
capable of developing required pressure in the sprayer system for many
spraying jobs. Different kinds of pump are employed in spraying machines
which include diaphragm pumps, medium pressure centrifugal pumps,
low-pressure ratary pumps of various types clear pumps and High
pressures and medium pressure piston pump.
Fitters /Strainer
These
are screening devices for separation. It is found in the suction line
between the tank and the pump to separate and remove foreign materials
which might affect operation of other functioning parts.
They are
usually found in the sediment bowl and can be easily removed for
cleaning. It should be replaced after cleaning fitter is wed for final
separation. It is finer than strainer and is usually found between the
tank-pump-nozzles. It is also used in nozzle orifice for separating
dirt.
Pressure Regulators
It is a device or mechanization that
minimum any pre-set pressure by passing some of the liquid back to the
tank i.e it sense as a safety device in automatically unloading the
excessive pressure.
It is also means for adjusting the pressure as required for the job.
Pressure gauge
It
provides guide to the operator in proper adjusting of the pressure for
each spraying job. It is usually connected on the discharge line.
Distributing systems
It
is a convectional hand gun which contain one or more nozzle it contain a
fast acting control values which are serve as a cut off and means of
adjusting the spraying pattern. Example is a hand held spraying gun in
knapsack sprayers.
Control values
It is used for quick flow control of any section or combination of sections of the boom nozzles.
Depending
on the mode of operation; there are two types of nozzles used on
sprayer. These are the said or pressure jet nozzles and the other ones
are the air atomizers. In solid nozzles, the liquid is atomized by the
nozzle under hydraulic pressure where as in the case of air atomizers,
the fluid is broken into fine particles either under hydraulic pressure
or jointly under hydraulic pressure and on air stream. Energy of the air
from the blower helps in sending the droplets to the target. The
principals parts of the nozzles are the body, wash, disk and cap. The
shut off may be provided I the supply line or in the nozzle itself. The
value is used to impart the whirling motion to the liquid as it flows at
high velocity through the value into the eddy chamber of the nozzle
body.
The hole at the centre of the nozzle disk results in a hollow
cone spray. If there is a hole through the centre of the value, a solid
cone of spray is provided. With increase of pressure, the dispersion of
droplets increase. The higher is pressure, the smaller the average
diameter of the droplets.

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Background to the study Sprayers are devices that are specially designed to spray liquid quickly and easily. They come in a number of different varieties. A sprayer is used to cover large area such as lawns quickly and easily. A boom sprayer of this type is typically used for spraying chemicals such as pesticides, herbicides, herbicides, insecticides and fungicides.Along with proper plant selection and cure, controlling pests in lawn or garden is an important par ...
