What is the hydraulic function?
The hydraulic function can be divided into: the power transmission mode, the hydraulic drive; The control mode is called hydraulic control. 1) hydraulic transmission is a liquid medium, which USES the pressure of the liquid to transfer power. Hydraulic control is controlled by a pressure liquid as a control signal. The control system composed of hydraulic technology is called hydraulic control system. Hydraulic control usually includes hydraulic open-loop control and hydraulic closed-loop control. Hydraulic servo control, hydraulic pressure closed-loop control, that is, it constitutes a hydraulic servo system, usually include electric hydraulic servo system (electro-hydraulic servo system) and mechanical hydraulic servo system (machine hydraulic servo system, or machine hydraulic servo mechanism), etc. The complete hydraulic system consists of five parts: the power component, the actuator, the control component, the non-piece and the hydraulic oil.
A complete hydraulic system consists of five parts: the power component, the actuator, the control element, the non-piece and the hydraulic oil. The power element is used 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. The function of the actuator, such as a hydraulic cylinder and hydraulic motor, is to convert the pressure of the liquid to the mechanical energy, and the driving load as a straight and reciprocating motion. The control element (i.e., various hydraulic valves) controls and regulates the pressure, flow and direction of the fluid in the hydraulic system
According to the control function, the hydraulic valve can be divided into the village force control valve, the flow control valve and the directional control valve. The pressure control valve is divided into the benefit flow valve (relief valve), pressure 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 the energy transfer energy in hydraulic system, there are various kinds of mineral oil, emulsified liquid and hydraulic oil.
There are a lot of hydraulic machines. The use is very broad, the jack. Lifting machine. The drill has something to do with it.
