Hydraulic pressIt can be said to be a kind of mechanical equipment that uses liquid substances to convert and transport energy to achieve industrial production. To put it bluntly, it is to use hydraulic pressure to realize the processing of parts. The system pressure of hydraulic press is divided into total system pressure and partial system pressure. Let's talk about how to adjust the system pressure according to the needs during machining?
To fully understand the adjustment method of hydraulic press system pressure, we must first make clear the hydraulic system schematic diagram of the hydraulic press. The hydraulic cylinder lifting and steering oil circuit of the hydraulic press are independent circuits for automatic leveling and guiding. When working, the hydraulic oil is diverted through the priority diverter valve in the plug-in electromagnetic directional valve, and is supplied to each hydraulic cylinder through the medium pressure oil pipe, and the return oil flows into the oil tank after being cooled. The system pressure of the hydraulic cylinder lifting and steering circuit is adjusted by the priority diverter valve set in the plug-in electromagnetic directional valve.
If you want to adjust the pressure of the total system, then you have to change the pressure of the hydraulic pump to achieve the goal. The hydraulic circuit formed by the main pump and the drive motor is the main circuit of the side wall extruder, which is used to drive the screw feeder. When working, the hydraulic oil is sucked out of the oil tank through the oil suction filter, and the main pump is equipped with a control slide valve to control the hydraulic oil to be supplied to the drive motor through the high-pressure oil pipe, and the return oil flows after being cooled by the radiator.
If you adjust the pressure of some systems, you have to adjust the valve. The overflow valve and the total system pressure should be adjusted at the same time! The function of the relief valve is to maintain the relief valve to adjust the pressure, that is, when the pressure is higher than the system relief valve to adjust the pressure, the relief valve to discharge oil and maintain the adjustment pressure. If the system pressure is lower than the adjustment pressure of the overflow valve, the system pressure is displayed, so if you want to adjust the system pressure of the hydraulic press, you can loosen the overflow valve first to see when the pressure decreases, which is the adjustment pressure of the overflow valve. If you want to adjust to the high level, you need to cooperate with the hydraulic pump and the overflow valve to adjust.
