What Is A Hydraulic Cylinder
The hydraulic cylinder is the hydraulic actuator that transforms the hydraulic energy into mechanical energy and makes a linear reciprocating movement (or swinging motion). It is simple in structure and reliable in work. It is used to realize reciprocating movement, can be removed from the deceleration device, and there is no transmission clearance, smooth movement, so in a variety of mechanical hydraulic system has been widely used.
The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; the hydraulic cylinder is basically composed of cylinder and cylinder head, piston and piston rod, sealing device, buffering device and exhaust device. The cushioning device and the exhaust device depending on the specific application situation, other devices are essential.
