Common fault analysis and elimination method for the pneumatic system of laser concrete leveling machine. In order to have a clearer understanding of the causes of the failure and the method of mastering the troubleshooting, we use the form of the following form to elaborate. The method of changing the trachea of the laser concrete leveling machine is to replace the trachea, which is twisted, compressed or leaked.
没有气压或压力不足，未打开空压机, 此时应重新起动; 空压机故障, 故障排除后重新起动; 空压机容量不够, 应重新配置大容量空压机; 调压阀压力调节太低, 应提高压力。找出负载增大原因, 然后予以排除。
No air pressure or pressure is insufficient, and no air compressor is opened. At this time, restart should be started. After air compressor failure, restart after failure, air compressor capacity is not enough, large capacity air compressor should be reconfigured, pressure adjustment of pressure regulating valve is too low, pressure should be increased. Find out the reason for the increase of the load and then remove it.
激光混凝土整平机升降气缸或板夹气缸不动作，电磁阀无信号，使电磁阀与控制回路分离, 单独给信号使其动作。如果电磁阀动作则是控制回路的问题; 若电磁阀不动作, 则应予以维修或更换。
The lifting cylinder or plate cylinder of the laser concrete leveling machine does not move, and the solenoid valve has no signal, so that the solenoid valve and the control loop are separated, and the signals are given to them individually. If the action of the solenoid valve is the problem of the control loop, the solenoid valve should be repaired or replaced if the solenoid valve does not move.
激光混凝土整平机速度控制阀能否对气缸速度进行控制能否进行流量调节。调压阀 压力表是否产生偏差调节手柄判断能否调节压力。将压力降至零, 确认压力表指示是否为零。
Whether the speed control valve of the laser concrete leveling machine can control the speed of the cylinder or not to adjust the flow rate. Whether the pressure gauge of the pressure regulating valve produces a deviation control handle to determine whether the pressure can be adjusted. Reduce the pressure to zero and confirm that the pressure gauge is zero.
