它产生的加速度大，时间常数小，对应速度快，动态性能优良。
The second type is the connecting hole, which includes the locating pin hole and screw hole (screw hole) for fixing the hydraulic valve, and the bolt hole (smooth hole) for connecting the manifold blocks in a pile; third
Case demonstration of hydraulic station
The function of hydraulic system is to increase the acting force by changing the pressure. A complete hydraulic system consists of five parts, namely, power component, executive component, control component, auxiliary component (accessories) and hydraulic oil. Hydraulic system can be divided into two categories: hydraulic transmission system and hydraulic control system. The main function of hydraulic transmission system is to transmit power and motion. The hydraulic control system needs to make the output of the hydraulic system meet the specific performance requirements. Usually, the hydraulic system mainly refers to the hydraulic transmission system.
