Hydraulic components include energy components, actuators,
The control element (i.e., various hydraulic valves) controls and regulates the pressure, flow and direction of the fluid in the hydraulic system. Hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves according to the control function. The pressure control valve is divided into overflow valve (safety valve), relief valve, sequence valve, pressure relay, etc. Flow control valves include throttle valves, adjustment valves, and diverter collector valves; Directional control valves consist of one-way valve, liquid control one-way valve, shuttle valve, reversing valve, etc. According to the control mode, the hydraulic valve can be divided into switch control valve, fixed value control valve and proportional control valve.
The auxiliary elements include the oil tank, oil filter, tubing and pipe joint, sealing ring, pressure gauge, oil level oil temperature meter, etc. Hydraulic oil is the medium of energy transfer energy in the hydraulic system, and there are various kinds of oil, oil, emulsion and hydraulic oil.
Executive components (such as hydraulic cylinders and hydraulic motors) is the function of the liquid pressure can be converted into mechanical energy, driving load for a straight line reciprocating movement or rotational motion.
You're right. A complete hydraulic system consists of five parts: the power component, the actuator, the control component, the auxiliary element and the hydraulic oil. The function of the power element is to convert the mechanical energy of the original motive into the liquid pressure energy, which is the oil pump in the hydraulic system, which provides the power to the whole hydraulic system. The hydraulic pump is structured in the form of gear pumps, vane pumps and plunger pumps.
