Use Of Hydro Pump For agriculture Application Mechanical Project (BUY)

Use of Hydropower:

Today, small hydropower projects offer emissions-free power solutions for many remote communities throughout the world such as those in Nepal, India, China, and Peru as well as for highly industrialized countries, like the United States. In the United States today, hydropower projects provide 81 percent of the nation’s renewable electricity generation and about 10 percent of the nation’s total electricity. That’s enough to power 37.8 million homes, according to the National Hydropower Association. The vast majority of the hydropower produced in the United States comes from large-scale projects that generate more than 30 megawatts (MW)—enough electricity to power nearly 30,000 households. Small-scale hydropower systems are those that generate between .01 to 30 MW of electricity. Hydropower systems that generate up to 100 kilowatts (kW) of electricity are often called micro hydro systems. Most of the systems used by home and small business owners would qualify as micro hydro systems. In fact, a 10 kW system generally can provide enough power for a large home, a small resort, or a hobby farm.

Use Of Hydro Pump For agriculture Application

Climate change concerns have brought a renewed focus on increased hydropower production as a potential replacement for electricity from fossil fuels. Hydropower currently accounts for about 6% of the electricity produced in the United States, and the generation of electricity from hydropower produces essentially no emissions of carbon. However, since most of the larger, more traditional hydroelectric resources have already been developed, a clean energy rationale for development of small and low-head hydropower resources may now exist. Power generation from rivers and streams is not without controversy, and the capability to produce energy from these sources will have to be balanced against environmental and other public interest concerns. That balance can be aided by research into new technologies and forward thinking regulations that encourage the development of these resources in cost-effective, environmentally friendly ways which recognize that such facilities, once built, can last for at least 50 years.

Concept Of Hydro Pump:

As we know that river water current has some velocity in the range 0.5-5m/s it poses an amount of kinetic energy & also the obvious need for agriculture is water, which is required to be pumped from river. So it is seems a good idea to pump that water by using the hydropower from the same river without any special construction. So we decided to put that idea in actual practice.

The basic concept is, run a water wheel by means of flow of river water current & use that power for pumping the water.

A- Foundation

B- Water wheel

C- Gear box

D- Impeller

E- Main shaft

F- Pedestal housing for bearing

Site survey:

Factors to be considered for site selection-

Velocity of flow
Head available
Flow rate
Flow characteristics
Feasibility of installation

By considering all above factors we select a site at CHIKURDE DAM, Warananagar as shown below

Conclusion:

From above results & analysis, it is seen that, the use of hydrokinetic energy to pump the water for agriculture fields is very economical. Though the initial & implementation cost of this project is more than conventional pump, but it recovers by the zero running cost. The payback or recovery period for 24 hour running 0.5 hp pump is found to be 16 months i.e. after 16 months, the use of Hydropump is totally cost free. Only small maintenance cost is required. In spite of above advantages, it also possible to run the pump of more power, by increasing the diameter of water wheel or mounting the no. of water wheels on the main shaft.

The site selection becomes the key factor in designing this types of projects. It’s because the site should have the required flow characteristics with the feasibility of installation & maintainability. If the site is feasible for installing, then use of Hydropump gives an uninterrupted & economical output.
