ABSTRACT
The objective of this project was to design, fabricate and experimentally investigate the
working of Pedal and Compressed Air Powered Centrifugal Pump which used in small
drinking water supply and garden irrigation. Pedal And Compressed Air Powered
Centrifugal Pump consists of a centrifugal pump operated by pedal power. The centrifugal
pump is positioned on its stand in such a way that driven shaft of the centrifugal pump is
butted to the bicycle wheel. By pedaling the bicycle, the bicycle wheel rotates, thereby
rotating the centrifugal pump which in turns discharges water from the sump. Pedal
And Compressed Air Powered Centrifugal Pump provides drinking water and irrigation in
remote areas where electricity is not available. Pedal And Compressed Air Powered
Centrifugal Pump is not only free from pollution but also provide healthy exercise. Pedal
And Compressed Air Powered Centrifugal Pump reduces the rising energy costs. Pedal
And Compressed Air Powered Centrifugal Pump is designed as a portable one which can
be used for irrigation in various places. The experimental investigation was executed and
performance of the Pedal And Compressed Air Powered Centrifugal Pump was carried out at
different rpm. The results indicate that the Pedal and Compressed Air Powered Centrifugal
Pump had given a considerable amount of discharge and head. The PPWP requires only
manual power thereby reducing the utility bill considerably. Experimental result shows that
discharge of about 0.00025m3/sec can be obtained for around 140rpm.
A person can generate four times more (1/4 horse power (hp)) by pedaling than by hand
cranking. At the rate of 1/4hp, continuous pedaling can be done for only short periods, about
10 minutes. However, pedaling at half this power (1/8 hp) can be sustained for around 60
minutes.
The main use of pedal power today is still for bicycling at least in the high-power range (75
watts and above of mechanical power). In the lower-power range there are a number of use of
pedal power for agriculture, construction, water pumping, and electrical generation that seem
to be potentially advantages, at least when electrical or internal-combustion engine power is
unavailable or very expensive.

CHAPTER 1
INTRODUCTION
Pedal power generation is the method of generating electrical power from mechanical
pedaling. It is a eco-friendly activity that causes no harm to the environment. This
technique, which has been influenced by bicycle pedaling, is the most resilient and robust
source of energy through all ages. With the emergence of modern electric powered
technologies, the use of pedal power has been sidelined and very rarely used to generate
electric power. With an efficiency of 97%, bicycle technology is nearly perfect. There are
a few inventors in India who have been innovating to utilize this power to substitute the
requirement of electric power for many other human activities.
By using electric operated Centrifugal pumps we can pump the water at a sub
class of dynamic Axis symmetric work absorbing machinery. Electrical operated
Centrifugal pumps are used to convert rotational kinetic energy to the Hydrodynamic
energy of the liquid flow. The rotational energy comes from electric device like motor.
The fluid enters the pump impeller along to the rotating axis and is accelerated by the
impeller, flowing radials in chamber outward into volute chamber, from where it exits.
Common uses include petroleum, water bodies, and petrochemical pumping. The function
of the centrifugal pump is converting potential energy of water pressure into mechanical
rotational energy.
The cycle operated mechanism consists of single centrifugal pump which is fixed
on the rear wheel bicycle. Paddling for few minute to pump 30-40 liters of water to a
height of 30 feet. Our project helpful for rural areas. Which are facing electric problem? It
can be used mainly for water lifting from wells and other water bodies. By cycle operated
centrifugal water pump which is run by rotating the pedal of a cycle. The system activated
a bicycle, rim, impeller, pulley and inlet and delivery pipes. Centrifugal pump is
mounted on Rear wheel of cycle which is operated due to the rotation of wheel which
creates the vacuumed in pump.
This research is useful for lifting water from different kinds of water bodies like
river, ponds, wells etc. by using a paddling We drive a bicycle, the rear wheel of the
bicycle rotates at particular rpm using paddle. And this wheel rotates the impellers of the
centrifugal pump by sliding action between wheel and pulley but the rpm of the wheel is
very low so we can’t get require head and power effort on the paddling is low so for

generating high speed in less power we can use the pulley which is mounted on the shaft
of the pump.
A centrifugal pump is one of the simplest equipment in any process of water lifting
plant. It convert energy of a prime mover (an electric motor or turbine) first into velocity
or kinetic energy and then into pressure energy of a fluid that is being pumped. The
energy changes occur by two main parts of the centrifugal pump, the diffuser and the
impeller. The impeller is the rotating part of mechanism that converts rotating energy into
the kinetic energy and the diffuser is the stationary part that converts the kinetic energy
into pressure energy.
1.1 COMPRESSED AIR POWER
The normal state of air, barometric, is called atmospheric pressure. When air is
compressed, it is under pressure greater than that of the atmosphere and it
characteristically attempts to return to its normal state. Since energy is required to
compress the air, that energy is released as the air expands and returns to atmospheric
pressure. Our ancestors knew that compressed air could be used for power when they
discovered that internal energy stored in compressed air is directly convertible to work.
Air compressors were designed to compress air to higher pressures and harness that
energy. Unlike other sources of power, no conversion from another form of energy such
as heat is involved at the point of application. Compressed air, or pneumatic devices are
therefore characterized by a high power-to-weight or power-to-volume ratio. Not as fast
as electricity, nor as slow as hydraulics, compressed air finds a broad field of applications
for which its response and speed make it ideally suited. Where there is an overlap, the
choice often depends on cost and efficiency, and air is likely to hold the advantage.
Compressed air produces smooth translation with more uniform force, unlike equipment
that involves translatory forces in a variable force field.
1.1.1 Reciprocating Single Acting Compressor
Reciprocating single acting compressors are generally of one-stage or two-stage
design. Compressors can be of a lubricated, non-lubricated or oil-less design. In the
single-stage compressor, air is drawn in from the atmosphere and compressed to final
pressure in a single stroke. The single-stage reciprocating compressor is illustrated in

Figure 1. Single-stage compressors are generally used for pressures of70 psi (pounds per
square inch) to 135 psi.

1.1.2 Pneumatic Motor
Air motors provide a continuous source of rotary power through a system
involving compressed air. Because they provide a slew of advantages over electric
motors, they are commonly used in a number of both high- and low-power applications.
According to Atlas Copco, a Swedish industrial company, the toughness and versatility of
an air motor make it an ideal power source for industrial applications.
A number of cylinders and pistons, or sliding pieces, make up piston motors. The
cylinders house pistons arranged in either an axial or radial fashion. Air moves into the
cylinder containing the pistons, and pressure acts on the pistons, causing them to slide
outward. This force makes the cylinder rotate, which creates the torque that turns the
motor.

The first step of making “Pedal and Compressed Air Powered Centrifugal Pump”
is the preparation of the stand. GI square pipes are made into sufficient pieces and
are welded together to get the stand.
The stand is then connected with the back wheel of the bicycle.
By considering the wheel and rotor shaft space the centrifugal pump is connected
with the stand by using the nut and bolts.
The suction and delivery pipes are then connected to the suction and delivery
ports respectively manual priming of the centrifugal pump is done next.
By pedaling the Rpm of the rotor shaft is measured using tachometer. The flow rate of
water is measured by using measuring tank and stop watch.

Pedal And Compressed Air Powered Centrifugal Pump is an eco-friendly water
pump. A water system includes a Centrifugal pump operated by pedal power. The pump
stand includes a housing in which a foot pedal and a drive shaft rotate. It works on the
principle of compression and sudden release of a tube by creating negative pressure in
the tube and this vacuum created in pump draws water from the sump. The this will
works on mechanical energy without electricity. Standard bicycle gearing components
can be assembled with a flexible coupling to create an inexpensive human powered
flywheel power unit. The centrifugal pump is positioned on its stand in such way that
driven shaft of the centrifugal pump is butted to the bicycle rear wheel. As the user
operating the pedal, the compressor will suck air from atmosphere and stored in tank that
air will used to run pneumatic motor ,the motor will coupled with rear will tire. The rear
wheel coupled with pump shaft by friction roller. By operating pedal and compressed air
gives maximum rotation of by that rotation pump will suck the water from the sump.
Useful for pumping water from rivers, ponds, wells and similar water sources. The
farmers can use this to pump water for irrigation in small farmland, garden irrigation and
to fill overhead tanks for domestic purpose. Most blenders use between 600-1500 watts
of energy, which clearly shows that besides burning calories, pedal power can
significantly contribute to reducing energy bills. This can be eliminating by using pedal
power.

DESIGN CONSIDERATIONS
5.1 PUMP SELECTION
The most suitable type of pump for this application was found to be a
centrifugal pump. Its compact size, simplicity of design, relatively low cost, light weight
and widespread availability of pumps and spare parts make it ideal for use in this project.
Centrifugal pumps are a well established technology and consequently their performance
is well understood. The performance of a centrifugal pump is governed by the impeller
diameter, rotational speed, input power and the output piping system. The pump affinity
laws give the relationship between head, flow rate, input power, rotational speed and
impeller diameter for centrifugal pumps.

5.3 MATCHING HUMAN CAPABILITY TO PUMP PERFORMANCE
Electrically powered pump heads are designed to work optimally at the specific
input power that is normally provided by the pump’s electric motor. It is therefore
important to find a pump with a rated electrical power that matches as closely as possible
with the power that a person can realistically generate on a bicycle. Figure 4.2 overleaf
shows how the power generated by people of varying fitness levels drops as the duration
of exercise increases. It is estimated that the Bicibomba Móvil will be used for around
20-30 minutes for each pumping session. Reading from Figure 4.2, healthy men can
expect to generate around 250 Watts when peddling for this period of time. The design
specification states that the Bicibomba Móvil should be able to be used by men, women
and children of varying sizes and fitness levels.

6.3 SUPPORTING CALCULATION
6.3.1 Axle Grip Deflection Analysis
Aim
To calculate the maximum deflection of the axle grips.
Assumptions
The supporting frame provides a rigid support for the axle grip tightener.
The deflection within the axle grip itself is negligible.
The diameter of the thread bar can be approximated to its pitch diameter, i.e. M16
thread→14.7mm.
The weight of the rider and bicycle is evenly distributed between the left and
right axle grips
Method
The point load, W, represents the weight of the peddler and the bicycle. In the
worst case scenario, the weight of the heaviest peddler, mpg, on the heaviest bicycle,
mbg will be entirely over the rear wheels. The weight, g(mb+mp), has been assumed to
be evenly distributed over the two axle grips, meaning that a force of ½g(mb+mp) is
exerted on each one. However, due to the effect of a suddenly applied loading occurring
Performance Evaluation of Pedal and Compressed Air Powered Centrifugal Pump
Department of Mechanical Engineering, VSMIT, Nipani, Dist-Belgaum. 17
as the rider mounts the bicycle, the loading force should be doubled[8]. Therefore:
W=g(mb+mp)=9.81m/s2*(20kg+100kg)=1177.2N
The moment, M, exerted by the force, W, acting at a distance, x, from the free end of the
axle grip tightener has magnitude: M=WX=1177.2N*97*10-3m=114.2Nm
The maximum deflections, δmax, of fixed end cantilever beams bent about principal axes
with point loads, W, and moments, M, applied at the free end are as follows:

The axle grip tighteneris manufactured from mild steel. Which has a Young’s Modulus.
E of 207 GPa. It has circular cross section of radius r of 7.5 mm.

Therefore, the deflection of the free end of the axle grips is given by the following

3×207×109×2.292×10−9
= 1.194×10-3
m ≈ 1 mm.
Conclusion
The deflection of the axle grips is just over 1mm.

6.3.2 Bearing Fatigue Analysis
Aim
To establish whether the bearings are able to withstand the increased loading
associated with converting the pump to bicycle power.
Assumptions
The force of the water in the pump head is evenly distributed across the impeller.
The self weight of the shaft, bearings and armature is negligible in comparison
with the contact force between the armature/driving roller and the bicycle tire.
The contact force between the bicycle tyre and the armature/driving roller does
not exceed 100N.
The axial force exerted on the impeller by the thrust washer does not exceed 20N.
The axial loading from the thrust washer is taken entirely by Bearing B
Method
The below figure shows the dimensions of the shaft assembly, with specific
reference to the locations of Bearings A and B.

armature

The reactions at the bearings are calculated using static force and moment balances:
ΣFV : Fr = RA + RB
Σ𝑀𝐵 = 𝑅𝐴 58 + 63 − 𝐹𝑟 × 63 = 0
Fr = 100 N
RA = 52.07 N, RB = 47.93 N.
The basic radial dynamic load rating, Cr, is the catalogue rating load that will give a life
of 1 million revolutions of the inner race and is given for the bearings shown in Figure
Performance Evaluation of Pedal and Compressed Air Powered Centrifugal Pump
Department of Mechanical Engineering, VSMIT, Nipani, Dist-Belgaum. 21
6.32a and 6.3.2b. Using the following equation, the expected life, L (millions of
revolutions) of the bearing can be calculated.
L = 𝐶𝑟
𝑅 𝑎
Where R is the radial loading at the bearing and for ball bearings, a = 3.
Bearing A
Cr = 6950 N, RA = 52.07 N L = 2377889.563 million Revolutions
Applied loading is so far below the bearing rated loading that bearing A will have virtualy
infinte life.
Bearing B
For the case of combine radial and thrust loading, the American Bearing Manufacturers
Association(ABMA) recommended using an equivalent radial force, Req,that would cause
the same amount of wear as both load combine the equivalent radial force can be found
using the following equation.
Req = XVR +YFa
Where V is the rotation factor and is equal to 1 for bearing with rotating inner ring. The
radial factor X and thrust factor Y are determined from the ratio of the axial force Fa to
the basic static load rating C0. The figure 5.32b shows that for bearing B, C0 = 4150 N.
Consequently Fa/C0 = 20/4150 =0.00482. For single row bearings, this gives
corresponding X and Y values of .56 and 2.86 respectively. Using these value, Req can
now be calculated,
Req = 0.56 × 1 × 52.07 + 2.86 × 20 = 86.35 𝑁
The equivalent radial force can now be used to calculate the life of bearing B.
Cr = 9650 N, Req = 86.35 N L = 𝐶𝑟
𝑅𝑒𝑞 𝑎
= 9650
86.35
3= 1395709 million revolutions.
Again the loading on the bearing B is so far below its rated capacity that the bearing will
have virtualy infinte life.
Conclusion
Both bearing can easily take the increased loading associated with converting the pump to
the bicycle power.

many rural powered water pump by use of this project we save electric power and We
will operate a water pump by using bicycle operated mechanism in the project and we can
lift the water. when we drive a bicycle the wheel of bicycle are rotate so we can provide a
pulley over the wheel for high rpm , the pulley is mounted on the shaft impeller of
impeller of the pump the impeller is rotate due to rotating of wheel with rotation of
pulley. So we operate the pump and lift the water at a particular head this project is
installed any of the place where water bodies. It can also be placed in garden, both
gardening & cycling can do simultaneously.
