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.
