To
understand the need of rams in hydraulic cylinders, we first need to understand
what a hydraulic cylinder is and how it works, in brief.
A
hydraulic cylinder is a mechanical tool that aids to transfer power by the
force of a piston in the cylinder that moves due to presence of high pressure
oil. Such a mechanism provides linear force by the hydraulic cylinder. The
cylinder basically comprises of 5 components. These parts are tube, rod, gland,
end cap and the piston. The piston rod that is part of the piston here is
referred to as a ram in a hydraulic cylinder and is one of the core parts of
the mechanical device. So what we are basically discussing here is the
hydraulic ram cylinder and how it works.
The
piston rod is mostly made of steel that is rolled by a plate of chrome. The
piston rod attaches to the piston at one end and then protrudes from the
cylinder through the head where the end of rod is present. There are two types of hydraulic ram cylinders – a
single piston cylinder and a double piston cylinder. Both have their own
mechanism in dealing with ram as the positions of pistons differ in both of the
types of hydraulic cylinders.
While
in double rod cylinders, there is a rod extending from both sides of the
piston, the single rod cylinders are the same as explained earlier. It may be
concluded that without a ram, hydraulic cylinders may not be as efficient as
they can actually be.
