Namely power components, executive components, control components, auxiliary components (accessories) and hydraulic oil. The operating process of the system is: the hydraulic motor and function of the power element provide oil pressure for the entire hydraulic system. After the programmable controller of the control system sets the parameters in the programming system, the control element opens and closes the valve under the action of electromagnetic drive. The body thus guides the flow direction of the hydraulic oil, and controls the execution unit to carry out corresponding actions by changing the flow direction.
