    • A square baler has a pick-up device, a feeding channel, a baling chamber with a baling ram, side walls of the baling chamber, a hydraulic adjustment device to change the position of at least one pivotal side wall and corresponding sensors and control devices, which regulate the side walls. A control device regulates the baling force of the square baler. A pressure sensor measures the baling pressure in the hydraulic adjustment device. The baling pressure is then compared with a set pressure value. The difference in the value of the pressures is processed via a PID controller, which sends an adjustment signal to a hydraulic valve for adjusting the difference in the actual and set pressures.
    • 方形打捆机具有拾取装置,进料通道,具有打捆机的打包机,打包机的侧壁,用于改变至少一个枢转侧壁的位置的液压调节装置和相应的传感器和控制装置 ,其调节侧壁。 控制装置调节方形打捆机的打捆力。 压力传感器测量液压调节装置中的打包压力。 然后将打包压力与设定的压力值进行比较。 通过PID控制器处理压力值的差异,PID控制器将调节信号发送到液压阀,以调节实际和设定压力的差异。
