INTRODUCTION
INTRODUCTION
- 7 -
This is a self – assessment test on the part of the students to assess his
competency in creativity.
During the course of study, the student is put on a sound theoretical
foundation of various mechanical engineering subjects and of course, to a
satisfactory extent. Opportunities are made available to him to work on different
kinds of machines, so that he is exposed to various kinds of manufacturing process.
As a students learn more and more his hold on production technology
becomes stronger. He attains a stage of perfection, when he himself is able to
design and fabricate a device.
This is the project work. That is the testimony for the strenuous training,
which the student had in the institute. This assures that he is no more a student, he
is an engineer.
This report discuses the necessity of the project and various aspects of
planning , design, selection of materials, fabrication, erection, estimation and
testing.

ABSTRACT
ABSTRACT
Electrically operated pumps and immersed jet pumps are widely
used in domestic, industrial and commercial applications. The capacity of these
pump heads varies from 5Meter to 100 meter . In many places , the drinking water
supplied by the government through the pipeline is below the ground level and are
- 9 -
collected in sumps of residential plots. The private agency supply the water through
the water tank lorry to many places where we have taken to multistoried building by
manually.
In this project , we consider this above problem in order to deliver the water
to the tank which is above the ground level and also to overcome the during the
electricity failure time we made a pedal operated reciprocating pump.
Working principle;
This pedal pump consists of a pair of foot pedal ,seating arragment, chain
drive , connecting rod , crank shaft, flywheel and a piston pump,
` The pedal is rotated by the foot and hence the chain rotates causes the
connecting rod rotates to reciprocate the piston via connecting rod... Thus the water
is discharged to tank without using electric power.
It is used to pump the water up to 25meters of pressure head. It could be very
useful in those areas where electricity is irregular or insufficient.

PROJECT PLANNING
PROJECT PLANNING
CONCEPT OF THE PROJECT
- 11 -
Before starting every project its planning is to be done. In a planning
functions are life the functions of nerves in our body. Planning a project is a very
important task and should be taken up with great care as the efficiency of the whole
project largely depends upon its planning, While planning a project each and every
details should be worked out in anticipation should be carefully considered with all
the relative provisions aspects.
PROJECT CAPACITY
The capacity of the project must be decided considering the amount of
money which can be invested. The availability of material and machines and
usefulness of the project.
DESIGN AND DRAWING
Having decided about the project to be manufactured at must be designed.
Design work should be done very considering all the relevant factors.
After design the project detailed drawing are prepared. Detailed
specification for raw material and finished products should be decided carefully
along with the specification of the machine required for the manufacture.
MATERIAL REQUIREMENTS
- 12 -
The list of material required for manufacture is prepared from the
drawing. The list is known as “Bill of materials”. Availability of these materials is
surveyed and purchased from the market.
OPERATION PLANNING
Next work of planning is to “select the best method” manufacture the
product, so that the wastage of materials, labor, machines and time can be
eliminated by considering various methods. The best method is to be selected for
fabrication and other works.
The proper method and proper person and the purposes of operation,
necessity operation, proper machine planning. The best method is the developed
and is applied to fabricate the project.
MACHINE LOADING
While planning proper care should be taken to find the machining time
for the operation as correct as possible. So that arrangement of full use of machines
can be made and the machine loading program can be decided.
PURCHASE CONSIDERATION
It is difficult to manufacture all the components needed for the project in
the machine shop. In each case, we should decide whether to make or buy about a
particular item. It is decided during the planning after making a complete study of
relative merits and demerits.
- 13 -
EQUIPMENT PROCEDURE
Results obtained from “operation planning” and machine loading help in
calculating the equipment require Specification of the equipment should be laid
down by considering then drawings. Drawings will also help in deciding the
necessary requirement of tools and accessories.

CONSTRUCTION
The project consist of
1. Foot Pedal
2. Chain drive
3. M.S. .Frame Stand
4. Crank shaft and connecting rod
5. Flywheel
6. Piston pump
7. inlet and outlet valve in pump cylinder
8. Suction and delivery pipeline with pressure gauges
9. operator seat
1. Foot pedal ;
This foot pedal is used to drive the pump by manually . A cycle pedal is
the part of a bicycle that the rider pushes with their foot to propel the bicycle.
Here in this kit,It provides the connection between the cyclist's foot or shoe and
the crank allowing the leg to turn wheel spindle and propel the crank wheel.
- 16 -
Pedals usually consist of a spindle that threads into the end of the crank and a
body, on which the foot rests or is attached, that is free to rotate on bearings with
respect to the spindle. Pedals were initially attached to cranks connecting directly to
the driven (usually front)sprocket wheel.
cycle pedal
2. Chain drive mechanism;
- 17 -
Chain drive is a way of transmitting mechanical power from one place to another.
It is often used to convey power to the wheels of a vehicle, particularly bicycles and
motorcycles. It is also used in a wide variety of machines besides vehicles.
Most often, the power is conveyed by a roller chain, known as the drive chain or
transmission chain,[1] passing over a sprocket gear, with the teeth of the gear
meshing with the holes in the links of the chain. The gear is turned, and this pulls
the chain putting mechanical force into the system.
This chain drive is used to transmit the rotary motion from the pedal wheel to crank
wheel. The driver sprocket has 50 tooth and the driven sprocket has 12 tooth. Hence
for every rotation is multiplied to four times the rotational output to crank wheel.
- 18 -
This chain drive is lubricated with oil using servo 60 oil in order to eliminate the
wear and corrosion.
- 19 -
3.Frame Stand
This base frame stand made in 40 mm x 3mm M.S. material square tube and is
used to hold the entire mechanism and support the operator seat also.
First of all the frame is designed and The base is constructed by
using the welded joints and cut the material with the required size by
using hacksaw machine.
The stand frame material is used to mild steel at low cost is widely
and is used
4. Crank and connecting rod mechanism;
- 20 -
A crankshaft has one (or more) offset sections where a connecting rod is attached
around it. The connecting rod moves back-and-forth (or up-and-down) ONCE for
every rotation of the crankshaft. The crank will always move in a circle, moving the
connecting rod in a smooth sine wave like motion. The power can flow in either
direction. That is, the crankshaft can drive the connecting rod, or the connecting rod
can drive the crankshaft.
5.FLYWHEEL;
A rotating mechanical device that is used to store rotational energy.
It acts like a reservoir and stores the energy in mechanical form
It Supply energy when required.
- 21 -
o Releases it when it is more then required.
Energy is stored by the formula
E = ½ Iω2
o Where “I” is the moment of inertia and it can vary for different shapes
of wheels. For solid disk the “I=Mr2/2”.
o “ω” is the rotational velocity and it is in (rad/sec).
• Fly wheel smoothen out variations in the speed of a shaft caused by torque
fluctuations if source of driving torque is fluctuating.
• It is also used to provide continuous energy in system.
It is also used to supply intermittent pulses of energy at transfer rates that exceed the
abilities of its energy source
Design Approach:-
There are two stages for it
• The degree at which energy is required to smoothen and its moment of inertia.
• The geometry of flywheel.
Design Parameters:-
• It depend upon acceptable changes in the speed.
Speed fluctuation:-
• The change in the shaft speed during a cycle is called the speed fluctuation
and it is given by
Fl =ωmax−ωmin
- 22 -
Geometry of Flywheel;
• It can be a solid cylindrical disc.
• It can be like conventional wheel design.
But energy requirements and size of the flywheel increases the geometry
changes to disc of central hub and peripheral rim connected by webs and to hollow
wheels with multiple arms.
- 23 -
Applications;
Typical applications for flywheels include;
• Dynamic balancing of rotating elements.
• Energy storage in small scale electricity generator sets.
• Automotive applications such as clutches.
- 24 -
6. piston pump;
• Pushing of liquid by a piston that executes a reciprocating motion in a closed
fitting cylinder.
• Crankshaft-connecting rod mechanism
• Conversion of rotary to reciprocating motion.
• Entry and exit of fluid
7. Inlet and outlet valve in pump cylinder
During the suction stroke the inlet valve is used to allow water into the
cylinder and at the same time the delivery valve is closed . During the delivery
stroke when piston moves in opposite direction and the outlet valve is used to
- 25 -
allow the water from the cylinder to outlet pipe line and at the same time the suction
valve is closed. the function of inlet and outlet valves are shown in figure.
8.Suction and delivery pipeline with pressure gauges;
Here 18MM DIA flexible PVC pipe line is connected at suction and delivery
pipe line in order to deliver the water from sump to tank. To show the
pressure a vaccum gauge is connected at the suction side and pressure gauge
is connected at the discharge side.
- 26 -
- 27 -
9.operator seat;
A bicycle seat, unlike a bicycle saddle, is designed to support the rider's
buttocks and back, usually in a semi-reclined position. Arthur Garford is credited
- 28 -
with inventing the padded bicycle seat in 1892, and they are now usually found
on recumbent bicycles.
10. BEARINGS;
A bearing is a machine element that constrains relative motion between moving
parts to only the desired motion. The design of the bearing may, for example,
provide for free linear movement of the moving part or for free rotation around a
fixed axis; or, it may prevent a motion by controlling the vectors of normal forces
that bear on the moving parts. Bearings are classified broadly according to the type
- 29 -
of operation, the motions allowed, or to the directions of the loads (forces) applied
to the parts.
A journal bearing consists of an approximately cylindrical body around a rotating
shaft. This journal bearing is used either for supporting a radial load, or simply as a
guide for smooth transmission of torque. Most common applications of bearings are
the plain circular bearings type (with a 360 degrees arc). Lubrication usage, on the
other hand, range from a simple inlet hole to axial, circumferential, and helical
grooves for efficient lubrication distribution.
The plain bearing applications include reciprocating sliders, rotating or oscillating
cylindrical members sliding in annular sleeves, and rotating or rotationally
oscillating disks sliding on mating disks.
The advantages of plain bearings are as follows:
- lower first cost- simple design- small radial space required- quiet operation
- not so sensitive to dust or grit- less likely to be subjected to fatigue failure- easy to replace
Materials:Plain bearings must be made from a material that is durable, low friction, low wear to the bearing and shaft, resistant to elevated temperatures, and corrosion resistant.#Babbitt (metal)#Bronze
- 30 -
#Graphite#Plastic-Solid plastic plain bearings are now increasingly popular due to dry-running lubrication-free behavior. Solid polymer plain bearings are low weight, corrosion resistant, and maintenance free.

9. operator seat
To function the pump , the operator sit on the seat and pedal
continuously. The foot pedal is used to drive the pump by manually . By
pedaling , the driver sprocket transmit rotary power to driven sprocket
though the chain drive. This chain drive is used to transmit the rotary motion
from the pedal wheel to crank wheel . The crank wheel converts the rotary motion
into linear motion of piston inside the cylinder. During the suction stroke the inlet
valve is used to allow water into the cylinder and at the same time the delivery
- 34 -
valve is closed . During the delivery stroke when piston moves in opposite
direction and the outlet valve is used to allow the water from the cylinder to outlet
pipe line and at the same time the suction valve is closed.
Thus the water is discharged to tank without using electric power.
