The speed regulating circuit of the hydraulic system of the hydraulic press is the core circuit. The hydraulic circuit selection for hydraulic press, must start with the selection of the speed regulating circuit (including determining the circulation method of the oil passage and the oil source structure method).
□ Speed regulating circuit
Select the speed regulating circuit according to the pressure, flow and power of the hydraulic actuator working condition diagram and the system's requirements for temperature, working stability, etc.
□ Rapid motion circuit and speed switching circuit
The rapid motion loop is closely related to the speed regulating loop. When selecting the oil source mode, system efficiency, temperature and other issues in the speed regulating loop, the rapid motion loop must be considered. Once the speed control loop is confirmed, most of the rapid motion loop is also determined. The structure of the speed switching loop is determined by the speed regulating loop and the rapid motion loop. When selecting a speed switching circuit, it is necessary to determine whether to choose a mechanically controlled switching method or an electrically controlled switching method according to the specific requirements of the system.
□ Pressure control circuit
When selecting various pressure control circuits, you should carefully consider the factors that need to be considered when selecting such circuits, their characteristics and applicable locations. For example, when selecting a pressure relief circuit, you must consider the power loss, temperature, flow and pressure instantaneous changes caused by pressure relief.
□ Multi-cylinder motion circuit
Compared with the single-cylinder motion circuit, the multi-cylinder motion circuit requires additional consideration of the interrelationship issues between multiple cylinders, that is, multi-cylinder action synchronization issues, mutual non-interference issues, sequential action sequence issues, and pressure relief issues when not in action.
For issues such as speed regulation, switching, and pressure limiting of each cylinder, selections are made based on the single-cylinder circuit, and some necessary adjustments are made when generating the hydraulic system.
