1台SP1250型沥青混凝土摊铺机,无论处于手动状态还是自动状态,行走时均向右跑偏。与行走跑偏有关的元件有:电气系统的转向电位器、右侧行走电磁阀、右侧行走马达转速传感器,液压系统的右侧行走泵,机械传动系统的右侧制动器和减速器等。通过多次试验,发现该机每次前进或后退时,右侧驱动链轮均能转动一下,随即转入静止,然后整机开始跑偏。既然右侧驱动链轮能转动一下,即可排除该机电气与液压系统元件存在故障的可能性,故障部位应是机械传动系统。但为避免走不必要的弯路,还是本
1 SP1250 asphalt concrete paver, whether in manual or automatic state, walking to the right deviation. The components related to running deviation are: the steering potentiometer of the electrical system, the traveling solenoid valve on the right, the traveling speed sensor on the right side of the traveling motor, the traveling pump on the right side of the hydraulic system, the right brake and the decelerator of the mechanical transmission system, and the like. Through many tests and found that each time the aircraft forward or backward, the right side of the drive sprocket can rotate about, then into the rest, then the machine began deviation. Since the right drive sprocket can rotate a bit, you can rule out the machine electrical and hydraulic system components there is the possibility of failure, fault location should be mechanical transmission system. However, in order to avoid unnecessary detours, still this
