Hydraulic press can be said to be a use of liquid material to transfer energy to achieve industrial production of mechanical equipment. To put it bluntly, the machining of parts is realized by means of hydraulic pressure. The pressure of hydraulic press system is divided into total system pressure and partial system pressure.
If you want to fully understand the pressure adjustment method of the hydraulic press system, first of all, the hydraulic system schematic diagram of the hydraulic press is clear. The hydraulic cylinder lifting and steering oil path of the hydraulic press is an independent loop, which is used for automatic leveling and guidance. When working, the hydraulic oil is distributed through the priority shunt valve in the cartridge electromagnetic directional valve, and supplied to each hydraulic cylinder through the medium pressure tubing, and the return oil flows into the tank after cooling. The system pressure of hydraulic cylinder lifting and steering loop is regulated by the priority shunt valve set in the cartridge electromagnetic directional valve.
If you want to adjust the pressure of the overall system, you do this by changing the pressure of the hydraulic pump. The hydraulic circuit formed by the main pump and the drive motor is the main circuit of the side wall extruder, which drives the screw feeder. When working, the hydraulic oil is sucked out from the tank through the oil suction filter, and controlled by the main pump with the slide valve, the hydraulic oil is supplied to the drive motor through the high pressure tubing, and the oil returns to flow after cooling by the radiator.
If you adjust part of the system pressure, then you have to adjust the valve, the relief valve and the total system pressure is to adjust at the same time! The function of the relief valve is to maintain the relief valve regulating pressure, that is, when the pressure is higher than the system relief valve regulating pressure, the relief valve will release oil and maintain the regulating pressure. If the system pressure is lower than the relief valve regulating pressure, the system pressure is displayed, so if you want to adjust the pressure of the hydraulic press system, you can first loosen the relief valve to see when the pressure decreases, which is the regulating pressure of the relief valve. If you want to adjust to the high, you need to cooperate with the hydraulic pump and the relief valve to adjust.
