A Brief Discussion on the Basic Principles and Components of Hydraulic Transmission Control Systems in Power Transmission Exhibition

1.1 Basic Principles

The hydraulic transmission control system mainly consists of four parts: power components, execution components, control components, and auxiliary components. Among them, power components are mainly used to meet the power requirements of system operation, that is, to convert mechanical energy into hydraulic energy, thereby providing sufficient hydraulic energy for the entire hydraulic transmission control system; The main function of the actuator is to control the pressure to be converted into mechanical energy, relying on hydraulic pressure to achieve rapid reversing of the equipment; The control element is composed of various hydraulic control valves, which control the pressure, flow rate, and flow direction of the oil from the hydraulic pump to the execution part, thereby controlling the force, speed, and direction of the execution part; Auxiliary components include auxiliary equipment such as pipelines within the system, mainly used for auxiliary functions such as connecting execution components and power components, ensuring the stable operation of power components, control components, and execution components, and effectively improving the operational efficiency of hydraulic transmission control systems. The hydraulic transmission control system needs to use the characteristics of the internal liquid as auxiliary power to maintain the hydraulic balance of the entire system. Its energy pressure transformation is controlled by the internal liquid as the carrier to match the pressure range of the piston.

1.2 System composition

The hydraulic transmission control system mainly consists of hardware system and software system. Composed of programmable logic controller (PLC), memory, editor, and input/output ports. The software system mainly consists of two parts: system program and user program. In software systems, PLC can achieve control over system functions. When the system control requirements change, it is necessary to change the corresponding functional control programs within the system. PLC has powerful application functions and reliability, which has a significant effect on improving the anti-interference ability of the system. The effective application of PLC in hydraulic transmission control systems can provide effective technical support for the stable development of the system.
