Basic knowledge of hydraulic control
in the operation of machines and equipment, many controls are carried out by hydraulic control mechanisms. In the case of continuous speed control, hydraulic control is usually more convenient and cheap. When the energy conversion efficiency is high, hydraulic control is often used together with servo control in electric control. This is because when many details need to be paid attention to in the installation process, "Wang Xianhong said that turning off the main motor source has become an electro-hydraulic actuator with the same efficiency and accuracy
