3. English materials and translations related to mechanical hydraulics, with a translation word count of over 5000! thank you!! _Baidu The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuating components, control components, auxiliary components (accessories), and hydraulic oil. The quality of a hydraulic system depends on the rationality of the system design, the performance of the system components, the pollution prevention and treatment of the system, and the last point is particularly important. In recent years, Chinas domestic hydraulic technology has greatly improved, and it is no longer simply using foreign hydraulic technology for processing. A complete hydraulic system consists of five parts, namely power components, actuating components, control components, auxiliary components (accessories), and hydraulic oil. The function of power components is to convert the mechanical energy of the prime mover into hydraulic pressure energy, referring to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, and plunger pumps. The function of executing components such as hydraulic cylinders and hydraulic motors is to convert the pressure energy of liquids into mechanical energy, driving loads to perform linear reciprocating or rotary motion. Control components (i.e. various hydraulic valves) control and regulate the pressure, flow rate, and direction of fluids in hydraulic systems. According to different control functions, hydraulic valves can be divided into pressure control valves, flow control valves, and directional control valves. Pressure control valves are divided into relief valves (safety valves), pressure reducing valves, sequence valves, pressure relays, etc; Flow control valves include throttle valves, regulating valves, diversion and collection valves, etc; Directional control valves include one-way valves, hydraulic control one-way valves, shuttle valves, directional valves, etc. According to different control methods, hydraulic valves can be divided into switch type control valves, fixed value control valves, and proportional control valves. Auxiliary components include oil tank, oil filter, oil pipe and pipe joint, sealing ring, quick change joint, high-pressure ball valve, rubber ho
