WATER PUMPING SYSTEM USING RIVER FORCE SYNOPSIS
Water pumping system using river force is equipment which is used to pump the water by using the river force. The power we are using in this equipment is river force. It is easily available and no cost. The main objective of this concept is to generate mechanical energy through river force with out using any other electrical energy or any other fuel based energies. SCOPE
Nowadays lot of the water pumping pumping devices are available in the market, they they are fully worked in bases of electrical power sources. The water pumping system using river force is a new innovative model used to pump the water, without based on any other electrical sources. So this concept is useful to generate the mechanical energy from the river force in order to reduce the manual pumping system sy stem and also save the electric power.
WORKING PRINCIPLE
The water pumping system using river force is the mechanical arrangements which is shown in the below diagram. The rotating shaft arrangement is coupled with the handle of the pump. So whenever the blade and shaft is rotated due to river force, the output from the river force is coupled with the pump. Here we are converting the rotary motion in to the linear motion. Also using bevel gear
arrangements for transmitting 90 degree power transmission. The efficiency of the pump depends upon the wind velocity.
BEVEL GEAR
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone.
Advantages of bevel gear
1.This gear makes it possible to change the operating angle.
2.Differing of the number of teeth (effectively diameter) on each wheel allows mechanical advantage to be changed. By increasing or decreasing the ratio of teeth between the drive and driven wheels one may change the ratio of rotations between the two, meaning that the rotational drive and torque of the second wheel can be changed in relation to the first, with speed increasing and torque decreasing, or speed decreasing and torque increasing.
Disadvantages of bevel gear
1.One wheel of such gear is designed to work with its complementary wheel and no other. 2.Must be precisely mounted. 3.The shafts' bearings must be capable of supporting significant forces.
Application of bevel gear
1.The bevel gear has many diverse applications such as locomotives, marine applications, automobiles, printing presses, cooling towers, power plants, steel plants, railway track inspection machines, etc.
2.Bevel gears are used in differential drives, which can transmit power to two axles spinning at different speeds, such as those on a cornering automobile. Bevel gears are used as the main mechanism for a hand drill. As the handle of the drill is turned in a vertical direction, the bevel gears change the rotation of the chuck to a horizontal rotation. The bevel gears in a hand drill have the added advantage of increasing the speed of rotation of the chuck and this makes it possible to drill a range of materials.
3.The gears in a bevel gear planer permit minor adjustment during assembly and allow for some displacement due to deflection under operating loads without concentrating the load on the end of the tooth.
4.Spiral bevel gears are important components on rotorcraft drive systems. These components are required to operate at high speeds, high loads, and for a large number of load cycles. In this application, spiral bevel gears are used to redirect the shaft from the horizontal gas turbine engine to the vertical rotor. Bevel gears are also used as speed reducers.
SPUR GEAR
A spur gear is a gear with teeth that project outwards from a cylindrical surface. Two spur gears are used to transmit power between parallel shafts.
In spur gears, the edge of each tooth is parallel to the axis of rotation and they mesh together when they are fitted to parallel shafts.Spur gears are the simplest form of gears.A spur gear is a gear with teeth that project outwards from a cylindrical surface. Two spur gears are used to transmit power between parallel shaft.
Advantages of Spur Gear:
1.Spur gears have high power transmission efficiency. 2.They are compact and easy to install. 3.They offer constant velocity ratio. 4.Unlike belt drives, spur gear drives have no slip. 5.Spur gears are highly reliable. 6.They can be used to transmit large amount of power (of the order of 50,000 kW).
Disadvantages of Spur Gear:
1.Spur gear drives are costly when compared to belt drives. 2.They have a limited center distance. This is because in a spur gear drive, the gears should be meshed and they should be in direct contact with each other. 3.Spur gears produce a lot of noise when operating at high speeds. 4.They cannot be used for long distance power transmission. 5.Gear teeth experience a large amount of stress.
Applications of Spur Gear:
Spur gears have a wide range of applications. They are used in: 1.Metal cutting machines 2.Power plants 3.Marine engines 4.Mechanical clocks and watches 5.Fuel pumps 6.Washing Machines 7.Gear motors and gear pumps 8.Rack and pinion mechanisms 9.Material handling equipments 10.Automobile gear boxes 11.Steel mills 12.Rolling mills
VERTICAL AXIS BLADES
Water pumping in rural areas is very important aspect which requires energy . Water sources like wells, dugouts, rivers are often used for agricultural fields. Power scarcity in rural areas is one of the major concerns in transportation of water from the sources to the agricultural fields. Wind energy is a significant source of renewable energy which can be used for pumping water in inaccessible localities. A wind pump is nothing but a windmill used for pumping water. It is one of the primary approaches of using the energy of the wind to pump water. Considering the available renewable energy resources, the generation of electrical energy &
mechanical energy by wind turbines has appeared as a feasible and commercial option.
Elements used for Pump
• Aluminum sheet and Aluminum Strips • Mild steel Rod and Mild steel Strips • Flange bearings • Bevel gears • uPVC pipes • Non-return valves and bushes
1.Aluminum Sheet and Aluminum Strips
Blades are one of the most important components of the wind turbine which influence the power productivity of the system. The area of blades is directly proportional to the wind energy absorbed by the system. In the present work, aluminum sheet is selected to make the blades and aluminum strip was used to provide the support for blade members.
2. Mild Steel Rods and Mild Steel Strips
The rotating shaft is the vertical shaft to which blade is mounted. Rotating shaft is supported with flange bearings. Mild steel strip is used to give support for blade at bottom side.
3. Flange Bearings
Bearings that are mounted within a flanged housing are used when the bearing mounting surface is perpendicular to a shaft axis. They are commonly available in two, three, or four-hole configurations. Four-bolt flanged ball bearing units have a square shape with 4 holes for mounting to accommodate higher loads than two-bolt flanges.
4. Bevel Gears
Gears are used for transmitting power from rotor to slider plate shaft. In this setup bevel gears are used to convert rotational motion of the shaft in vertical axis in to horizontal axis to rotate the slider plate in horizontal axis. The selected bevel gear is of module 2.62mm and number of teeth in pinion is 15 teeth and in gear is 30 teeth.
5. uPVC Pipes
In this work uPVC pipes were used to make the piston pump. Because uPVC pipes have more thickness than normal PVC pipes which has better strength. The whole setup of valves, plunger, caps and piston body are of same material.
6. Non-return Valve
Non return valve or one way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. These valves are two port valves, meaning they have two opening in the body, one for fluid to enter and other
for fluid to leave. In this setup, the non-return valve of brass material were selected.
