(1) Hydraulic drive schematic diagram of the cutting machine A schematic diagram consisting of various hydraulic components, accessories and connection symbols to represent the working principle of a hydraulic system, called hydraulic transmission schematic. There are two ways to express graphical symbols: a schematic diagram of the structure, which is relatively straightforward and the structural features of the components are clear. However, the graphics are too complicated to lock, and the drawing is troublesome; the other is a graphical symbol diagram, that is, various types of hydraulic components are represented by their graphical symbols.
(2) Components are composed of several different parts, which are used to perform specific functions, such as hydraulic cylinders, hydraulic motors, hydraulic pumps, valves, fuel tanks, filters, accumulators, coolers and pipe streets. Etc; these components are generic and standardized.
(3) Circuit The hydraulic circuit is a typical part of a component that performs a specific function.
(4) System The hydraulic system is the entire transmission system consisting of circuits to control and drive the hydraulic machinery to perform the required work.
