Design and Realization of Hydraulic Cylinder
Region - Water Conservancy, 2018 A device that converts hydraulic energy from a hydraulic cylinder to mechanical energy is known as actuator. The actuator is a direct performer, and has the opposite role of the hydraulic pump from the point of view of energy conversion. According to principle of energy conversion, the actuators can be divided into three types: hydraulic motors ...
