WATER PUMPING SYSTEM USING WIND POWER
Abstract
Aero turbines convert wind energy into rotary mechanical energy. A mechanical
interface, consisting of a step-up gear and a suitable coupling transmits the energy to a
reciprocating water pump. The wind mill blade is coupled to the cam plate and it will
rotate according to the wind speed. The cam shaft coupled to pneumatic reciprocating
water pumping system.
INTRODUCTION
Windmills have been used to pump water since as early as the 7th century, in
Persia. Popularly identified with Holland where they are instrumental in draining the

• Traditional mechanical ater !"m!in# indmills$ These are windmills
located at the water source. They employ a simple mechanical system of
multiple blades on a turning wheel or rotor". A cran!, mounted on the rotor
shaft, moves up and down with the turning of the mill. This is how the water
is lifted and pumped. They are limited by the fact that they have to be located
at the water source.

AD-ANTAGES O* WIND ENERGY CON-ERSION SYSTEM
The ma'or advantage of this design is that the rotor blades can accept the wind
from any compass.
Another added advantage is that the machine can be mounted on the ground
eliminating tower structures and lifting of huge weight of machine assembly, i.e. it
can be operated close to the ground level.
%ince this machine has vertical a#is symmetry, it eliminates yaw control
re(uirement for its rotor to capture wind energy. A dual purpose and relatively
simple shaft a#is support is anticipated as well as ground level power outputdelivery due to presence of vertical shaft. This may in turn, allow easier access
and serviceability.
Airfoil rotor fabrication costs are e#pected to be reduced over conventional rotor
blade costs.
The absence of pitch control re(uirements for synchronous operation may yield
additional cost savings.

APP&ICATIONS
Direct heat a!!lications
echanical motion derived from wind power can be used to drive heat pumps or
to produce heat from the friction of solid materials, or by the churning of water or other
fluids, or in other cases, by the use of centrifugal or other types of pumps in combination
with restrictive orifices that produces heat from friction and turbulence when the wor!ing
fluid flows through them. This heat may then be stored in materials having a high heat
capacity, such as water, stones, eutectic salts, etc.,
A home heating system that uses a wind powered pump and a restrictive orifice to
derive direct heat for a building, without first generating electricity also has been
developed.
