The hydraulic system consists of two parts: signal control and hydraulic power
The signal control part is used to drive the control valve of the hydraulic power part, and the hydraulic power part is represented by a circuit diagram to show the relationship between different functional components. The hydraulic source includes hydraulic pumps, motors, and hydraulic auxiliary components. The hydraulic control part includes various control valves for controlling the flow, pressure, and direction of the operating oil. The performance part includes hydraulic cylinders or hydraulic motors, which can be selected according to actual needs. Hollow arrows represent signal flow, while solid arrows represent energy flow. The action sequence of the basic hydraulic circuit - the direction and spring return of the control element (dual position four-way directional valve), the elasticity of the actuating element (double acting hydraulic cylinder), and the opening and closing of the safety valve. As for the implementation and control components, they are based on the corresponding circuit diagram symbols and are prepared to introduce circuit diagram symbols. According to the working principle of the hydraulic system, you can sequentially number all circuits.
If the component identifier corresponding to the executor extension is even, then the component identifier corresponding to the executor recycling is odd. To identify system faults, it is not only necessary to number the hydraulic circuit, but also to number the actual equipment. If the entire system only has one device, the device number can be omitted.
In practice, another numbering method is to sequentially number all components in the hydraulic system. At this point, the component number should be the same as the number in the component list. This method is particularly suitable for complex hydraulic control systems, where each control circuit corresponds to a system number.
