1. Understand the purpose of the hydraulic press system, divide the schematic diagram of the hydraulic press system into three blocks in turn: actuators, power components, and control components, and then master the actions and requirements of the actuators according to the requirements of the host.
2. Find out the type, performance, relationship, and function of each hydraulic component. First, read hydraulic cylinders or hydraulic motors; then read and understand various control devices and variable mechanisms, and finally, read and master auxiliary devices. On this basis, the system is divided into a corresponding number of basic circuits according to the analysis of the work cycle and work performance requirements, and each circuit is found one by one on the hydraulic transmission schematic diagram.
3. According to the work cycle table, carefully analyze and write out the corresponding inlet oil and return oil flow routes for each action. In order to facilitate analysis, it is best to number each hydraulic component and each oil circuit in the hydraulic press system before analysis.
4. When reading the schematic diagram of the hydraulic press system, also pay attention to whether the main oil circuit and the control oil circuit are contradictory and whether they interfere with each other. On the basis of analyzing each action oil circuit, the action sequence table of an electromagnet and other conversion elements is listed.
