液压输出是拖拉机功率输出的一种重要方法 ,以液压能的形式将动力输出。主要参数是压力、流量。在进行东方红 1 0 0 4/ 1 2 0 4大功率拖拉机液压输出功率台架试验时 ,发现空载输出流量大大小于设计值。设计要求的空载流量为 45 L / min和 5 0 L / min,而测量结果仅为 2 0 L / m Hydraulic output is an important method of tractor power output, the power output in the form of hydraulic energy. The main parameters are pressure, flow. During the test of hydraulic output power of Dongfanghong 1 0 0 4/1204 high-power tractor, it was found that the no-load output flow rate is much smaller than the designed value. The design requirements of no-load flow of 45 L / min and 50 L / min, and the measurement was only 20 L / m
