1.故障现象1台ABG423型摊铺机大修后调试时,操作人员将方向电位器设置在中位、快慢挡开关设置在慢速挡位时,行驶正常。将方向电位器设置在中位、快慢挡开关设置在快速挡位且速度不高于4m/min时,摊铺机可直线行驶;但是当速度大于4m/min时,摊铺机前进向右跑偏,后退则向左跑偏。摊铺机行走跑偏现象一般可分为以下3种:一是起步跑偏,即摊铺机起步时,虽方向电位器在中位,但摊铺机在左、右晃动1到2次之后,方能直线行
1. Symptom 1 ABG423 paver overhaul after debugging, the operator will set the direction of the potentiometer in the median, the speed of the gear switch is set to slow gear, driving normally. Set the direction potentiometer in the neutral position, the speed limit switch is set in the fast gear and the speed is not higher than 4m / min, the paver can run in a straight line, but when the speed is more than 4m / min, the paver advances to the right Partial, back to the left deviation. Paver walking deviation can generally be divided into the following three kinds: First, start deviation, that paver start, although the direction of the potentiometer in the middle, but the paver in the left and right shaking after 1 or 2 times , Can only be a straight line
