ABSTRACT This project is developed for the users to lift any weight using air pressure. High pressure air is stored in a tank. A
cylinder with piston arrangement is connected with a zig-zag pattern. Two pipes connected with ball valves connect
the air tank with the cylinder. When one valve is opened, the air rushes out into the cylinder. Therefore the piston moves in one direction.
The rod connected with the piston pushes the zig-zag frame so that the lift moves up. When the other ball valve is opened, the air inside the
cylinder is released. Therefore the lift comes down.
1. INTRODUCTION
1. 1 PNEUMATICS
Pneumatics is a section of technology that deals with the study
and application of pressurized gas to produce mechanical motion.
Pneumatic systems that are used extensively in industry
and factories are commonly plumbed with compressed air or
compressed inert gases. This is because a centrally located and
electrically powered compressor, that powers cylinders and
other pneumatic devices through solenoid valves, can often
provide motive power in a cheaper, safer, more flexible, and
more reliable way than a large number of electric motors and
actuators
1. 2 Comparison to hydraulics
Both pneumatics and hydraulics are applications of fluid
power. Pneumatics uses an easily compressible gas such as
air or a suitable pure gas-while hydraulics uses relatively incompressible
liquid media such as oil. Most industrial pneumatic
applications use pressures of about 80 to 100 pounds
per square inch (550 to 690 MPa). Hydraulics applications
commonly use from 1, 000 to 5, 000 psi (6. 9 to 34. 5 MPa),
but specialized applications may exceed 10, 000 psi (69
MPa).
1.3 Components used in for zig-zag pneumatic lift
The main parts of the zig zag pneumatic lift system are:
· Pneumatic Cylinder
· Single stage reciprocating air compressor
· Ball valves
· Atmospheric Pressure
2.ZIG ZAG PNEUMATIC COMPONENTS:
2.1 Operation
General
Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force on the piston. Consequently,
the piston becomes displaced (moved) by the compressed
air expanding in an attempt to reach atmospheric pressure
CONSTRUCTION AND WORKING
This project is developed for the users to lift any weight using air
pressure. High pressure air is stored in a tank. A cylinder with
piston arrangement is connected with a zig-zag pattern. Two
pipes connected with ball valves connect the air tank with the
cylinder. When one valve is opened, the air rushes out into the
cylinder. Therefore the piston moves in one direction. The rod
connected with the piston pushes the zig-zag flame so that the
lift moves up. When the other ball valve is opened, the air inside
the cylinder is released. Therefore the lift comes down.
The main objective of Zig-Zag Pneumatic Lift project is developing
a lift system for lifting any weight using air pressure. In this
project, we stored high pressure air in a tank. A zig-zag pattern
is connected with a cylinder with piston arrangement.
The cylinder and the air tank are connected by the two pipes
with ball valves. When one ball valve is opened, the high pressure
air will enter into the cylinder. Hence, the piston will move
in one direction. The rod connected with the piston pushes the
zig -zag frame so that the lift moves up. When we open the other
ball valve, the air inside the cylinder is released. So, the lift
comes down.
CONCLUSION:
We make this project entirely different from the other projects.
The concept involved in our Project is very easy. We use pneumatic
cylinder with piston attached inside and this cylinder is in
turn attached to a zig-zag frame and when the compressed air
is passed through the tube it makes the cylinder working and
in return the lift will start to raise to its maximum height and
when the air flow is made to stop then the lift will come back
to its original position. By doing this project we understood the
working principle of a zig-zag pneumatic lift their benefits, advantages
and disadvantages.
We have successfully completed the project work at our institute.
Once again we express our sincere thanks to all our staff members
who made our dream come true.
