INTRODUCTIONS
Hydraulic cylinder is the hydraulic energy into mechanical energy,
reciprocating motion to do (or swing movement) of the hydraulic
actuators. It is simple, reliable. Use it to achieve reciprocating
movement can be removed from deceleration devices, and no
transmission gap, smooth motion, so in a variety of machines are
widely used in hydraulic systems. Hydraulic cylinder output force
and the effective area of the piston is proportional to the
pressure difference on both sides; hydraulic cylinder is basically
a cylinder and cylinder head, piston and piston rod, seals,
cushioning device and the exhaust composition.Buffer device and the
exhaust depending on the specific application of the occasion,
other devices are indispensable.
Cylinder and cylinder of the advantages and disadvantages:
1. As the pneumatic system uses pressure is generally in the range
of 0.2-1.0Mpa, so the cylinder is the driving force can not do
high-power components. Hydraulic cylinders can be done relatively
large power device, use the hydraulic system;
2. From the media about the air can be unlimited, no cost and
supply difficulties, the gas will be used directly into the
atmosphere, convenient, no pollution, hydraulic oil is the
opposite;
3. The air viscosity is small, the resistance to less than the
hydraulic oil;
4. But the air is much larger than the compression rate of
hydraulic oil, so it's working smoothly and to respond to far
backward in this regard.
Hydraulic cylinder hydraulic system is the most important
components of implementation, it can convert mechanical energy of
hydraulic and matched with a variety of transmission to complete
all of the mechanical movement. Hydraulic cylinder has a simple
structure, the output force, stable and reliable performance and
easy maintenance, wide range of applications and so on.
