Http://www.czdrx.com hydraulic cylinder hydraulic cylinder is hydraulic energy into mechanical energy, make linear reciprocating motion (or swing movement) of the hydraulic actuator. Its simple structure, reliable work. Use it to achieve reciprocates deceleration devices can be removed, and there is no backlash, smooth motion, so in a variety of mechanical hydraulic system has been widely used. Output force of hydraulic cylinder and piston effective area and is proportional to the pressure difference on both sides; essentially of hydraulic cylinders and cylinder head, piston and piston rod seals, buffer means and the exhaust system components. Cushioning device and exhaust depending upon the application, the other device is essential.
