During the study of liquid filling systems’ performance using a
piston driven by a pneumatic piston, all parameters having an
influence should be considered. One of these parameters is the
piston pressure and its influence on the velocity of the p
iston. This
influence will be explained in this paper.
In liquid filling systems using a cylinder with a reciprocating piston driven by
pneumatic cylinder,
In the filling stroke there are a lot of parameters affecting these systems and their
performances ,one of these parameters is a piston stroke len
gth.
In this paper the influences of a piston stroke length and their parameters on the
velocity of the piston has been studied in order to reach the optimum piston stroke length.
First the mathematical module of velocity of the piston and the length of the stroke
and other parameters is extracted, then experiments are done using a special testing stand
equipped by all control and measuring tools.
All reading data are converted into graphs.
The results show that In liquid filling systems there is an ideal value range for the
piston stroke length.
Most robotic industries depend on using (servo motors) and (stepper
motors) orcontinuous current motors (DC motors) for movement
transition, which increases the cost and complicates the robot’s
controlling process, as well as its driving circuits.
This essay deals with using pneumatic in the new design and
building of a robot’s arm, that can manage to do many tasks with a
much lower budget than the one needed for any of the above
mentioned methods, that’s because it can be used for tasks that need
high speed and capacity, but don’t need precision.
