双面钻孔卧式组合机床液压系统（Hydraulic system of double - side drilling horizontal combination machine tool） intro Scraper hydraulic system A complete hydraulic system consists of five parts, namely power elements, actuators, control elements, auxiliary components (accessories) and hydraulic oil. Power element The power element is used to convert the mechanical energy of the original motive into the pressure of the liquid, the oil pump in the hydraulic system, which provides the power to the whole hydraulic system. The structure of hydraulic pump usually has gear pump, vane pump and plunger pump. actuators The function of an actuator (such as a hydraulic cylinder and a hydraulic motor) is to convert the pressure of the liquid to mechanical energy, driving the load as a straight reciprocating movement or rotary motion. Control element The control element (i.e. various hydraulic valves) controls and regulates the pressure, flow and direction of the liquid in the hydraulic system. According to different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valve is divided into overflow valve (relief valve), pressure relief valve, sequence valve, pressure relay, etc. Flow control valve includes throttle valve, adjusting valve, diversion valve and so on; Directional control valve includes one-way valve, liquid control one-way valve, shuttle valve, reversing valve, etc. According to the control mode, hydraulic valve can be divided into switch control valve, fixed value control valve and proportional control valve. Auxiliary components Auxiliary components include fuel tank, oil filter, tubing and pipe joint, sealing ring, quick change joint, high pressure ball valve, rubber tube assembly, pressure gauge joint, pressure gauge, oil level meter, oil temperature meter, etc. The hydraulic oil Hydraulic oil is the working medium for the transmission of energy in the hydraulic system, and there ar
