General rod cylinder
The structure of the tie-bar hydraulic cylinder is DAO compact and simple, smaller than the hydraulic cylinder of the same pressure class, the working pressure is 7MPa, 14MPa, the cylinder is 40~250mm, the ambient temperature is ~10℃~ 80℃.
Rod type hydraulic cylinder is mainly used in machine tools, woodworking machinery, rubber machinery, iron and steel equipment, injection molding machine, die casting machine, offshore or ship installation.
Hydraulic cylinder has a single out and double out, that is, the piston rod can move in one direction and two - way can be moved in two forms.
The hydraulic cylinder is the hydraulic actuator that changes the hydraulic energy into mechanical energy and does reciprocating motion (or oscillating motion) in a straight line.It is simple in structure and reliable in operation.When it is used to realize reciprocating motion, the deceleration device can be removed, and there is no transmission gap, the motion is stable, so it is widely used in all kinds of mechanical hydraulic system.
The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides.The hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.Buffering devices and exhaust devices depend on the specific application; other devices are essential.
Hydraulic drives have cylinders and motors that convert the pressure energy of a liquid into mechanical energy and output it.Cylinder is mainly output linear motion and force.
Hydraulic cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action it can be divided into single action and double action.
Piston cylinder, plunger cylinder is mainly used in: machinery, such as excavator;Scientific research, such as university structural laboratory.
Plunger cylinder is used for pressure testing machine, such as Ji 'nan gold test, rethink the testing machine for material testing.
