First, the pressure sensor is the basis for accurate adjustment. High-precision pressure sensors are installed at key stress-bearing parts to monitor pressure data in real time and convert them into electrical signals for feedback to the control system. The system compares the preset pressure parameters with the feedback signal and calculates the adjustment amount quickly and accurately through the PID (proportional-integral-differential) control algorithm to achieve dynamic adjustment of pressure.
Secondly, the optimization of the hydraulic system is crucial. The hydraulic pump, relief valve, reversing valve and other components work together. The relief valve sets the maximum pressure of the system to prevent excessive pressure from damaging the equipment; the reversing valve controls the flow direction of hydraulic oil and pressure release, and achieves accurate control of the pressing force by adjusting the displacement and pressure of the hydraulic pump. For example, when pressing materials of different hardness, the output pressure of the hydraulic pump can be adjusted to ensure that the pressure is stable and meets the process requirements.
Furthermore, the automated control program is indispensable. Modern briquetting presses are mostly equipped with PLC (Programmable Logic Controller) control systems, which can preset different pressure curves and pressing programs according to material characteristics, molding requirements, etc. The operator only needs to enter parameters in the human-machine interface, and the system can automatically complete the precise adjustment of pressure and control of the pressing process.
In addition, regular calibration and maintenance of the pressure control system are also very important. Regularly calibrate the pressure sensor to ensure accurate measurement data; check the sealing of the hydraulic system pipeline to prevent pressure leakage; replace worn hydraulic components in time to ensure stable system performance. Through these measures, the precise adjustment of the Briquetting Press pressure control system can be effectively guaranteed, and the working efficiency and product quality of the equipment can be improved.
