AC hydraulic power unit: The hydraulic power unit is a kind of energy transmission that uses pressure as the working medium. Conversion and control of the transmission system. Compared with machinery, hydraulic transmission has a large power-to-mass ratio, flexible layout and can realize multiple technical advantages such as stepless speed regulation. It is used in modern industry, agriculture, construction, aerospace, river and sea engineering. It is widely used in scientific experiments, public facilities and environment. The hydraulic power source is generally composed of five relative components: hydraulic pump set, fuel tank component, temperature control component, filter component and energy storage component; 1) Energy device-hydraulic pump. It converts the mechanical energy output by the power part (electric motor or other remote motor) into hydraulic energy, and provides pressure oil to the system. 2) Actuating device-hydraulic press (hydraulic cylinder, hydraulic motor). Through it, it converts hydraulic energy into mechanical energy and pushes the load to do work. 3) Control system device-hydraulic valve. Through their control and adjustment, the pressure, flow rate and direction of the liquid flow can be changed, thereby changing the force (or torque), speed and direction of the actuator. According to the different control functions, the hydraulic valve can be divided into For the village force control valve, flow control valve and direction control valve. Pressure control valve is divided into flow control valve (safety valve), pressure reducing valve, sequence valve, pressure relay, etc.; flow control valve includes throttle valve, regulating valve, diverter and collector valve, etc.; direction control valve Valves include one-way valves, hydraulic control one-way valves, shuttle valves, reversing valves, etc. According to different control modes, hydraulic valves can be divided into on-off control valves, fixed-value control valves and proportional control valves. 4) Auxiliary devices-fuel tanks, pipelines, accumulators, oil filters, pipe joints, pressure gauge switches, etc. These components are used to connect the system to achieve various working cycles. 5 Working medium-hydraulic oil. Most hydraulic oil uses mineral oil, which is used by the system to transfer energy or information. Gongliang AC hydraulic power unit is available in 220V and 380V. The hydraulic power unit (HPU) is used as an oil supply device. It is connected to a number of hydraulic cylinders through an external pipeline system to control the actions of multiple sets of valves. Oil tank, oil pump and accumulator form a separate and closed power oil source system. The oil station can be equipped with a PLC control system, which controls all internal hydraulic functions and generates signals to exchange with the control room (DCS).
