Paver deviation of the law, how to solve?
From the analysis of the electronic control system, there are mainly 3 reasons for the deviation of the paver to one side:First, the steering potentiometer assembly is not good or medium drift. With the testing device of steering potentiometer and turn trimmer potentiometer, if it were in place, but the side turn signal, and the other side without turning signal, by resetting the steering potentiometer and turn trimmer potentiometer, can solve the problem.Two is the speed sensor damage. A speed sensor is detected by a detecting device. If the speed signal on one side is zero, the side speed sensor is damaged. Replace the side speed sensor at this time.Three is proportional solenoid valve, solenoid problems. If the electromagnetic valve solenoid individual differences exist, even if the starting current is the same, the walking pump output will be different, resulting in different speed of the walking motor. At this point, the starting current can be corrected by adjusting the starting current.
Its reason and solving method of paver walking deviation can be roughly divided into to the side of the deviation and irregular (huzuohuyou) deviation of 2, this paper analyzed the reasons, and puts forward the solving method. (1) to the side of the deviation of mechanical transmission in the left and right motor running speed (pulse) consistent with the premise, from the analysis of mechanical transmission, paver to cause deviation of the main side there are 3: one is the left and right track tensioner are not the same. At this point, you can adjust the track to tighten the degree of elimination of deviation. Two is left, right track is not parallel. At this point, by adjusting the track guide wheel positioning bolts, or adjust the controller deviation parameters to eliminate deviation. Three is the track beam because of poor rigidity or stress release and other reasons deformation. At this time, the track beam can be eliminated by adjusting or replacing the track beam. Hydraulic transmission from the hydraulic transmission analysis, paver to one side of the deviation mainly because there are 2: first, the gear is not correct. The main reason for the hydraulic system, which does not take into account the electrical system, is that the motor shift is switched abnormally. The speed of the left and right running motors is detected by the test equipment. If there is a difference in speed, it is likely that one side is a working block and the other side is a running gear. At this time, adjust or replace the walking motor, so that the left and right gear to maintain the same, the phenomenon of deviation can be eliminated. Two is the running motor in the open-loop state, or the left and right sides of the motor speed difference is too much.
