First, the output flow of the straw baler oil pump is not enough and the output pressure is not high.
Second, the overflow valve is permanently deformed by the spring, the main valve center damping hole is partially blocked, and the main valve core is stuck in the position of the small opening, so that the pressure oil outputted by the oil pump partially overflows into the oil tank, so that the straw baler system is passed to the actuator The effective flow rate is greatly reduced, so that the speed of rapid movement is not enough.
Third, the internal and external leakage of the straw baler system is serious: the general working pressure is lower when fast forward, but it is much higher than the return oil pressure. When the piston seal of the cylinder is damaged, the two chambers of the cylinder leak greatly due to the cavity, so that the rapid movement speed of the cylinder is insufficient, and the internal and external leakage of other parts may also occur.
Fourth, the guide rail is lubricated and oil-cut, the installation accuracy of the cylinder and the assembly precision are poor, which causes the frictional resistance to increase when fast-forward.
