1、分配阀活塞漏气

1. Distribution valve piston leaking

故障原因：当踩下自上料水泥搅拌车的制动踏板时，大量压缩空气从挂车控制阀漏出，很快将挂车贮气筒内的压缩空气漏完，失去制动作用。

Fault cause: When the brake pedal of the self feeding cement mixer truck is pressed, a large amount of compressed air leaks out from the trailer control valve, quickly leaking out the compressed air in the trailer air storage cylinder and losing its braking effect.

扫除故障：将分配阀拆下检查，若是磨损、破裂应实时更换。

Troubleshooting: Remove the distribution valve for inspection, and replace it in real time if it is worn or broken.

2、挂车刹车不灵

2. Trailer brake not working properly

故障原因：挂车控制阀的压力调节螺钉拧得过松，使挂车贮气筒压力过低、或管路中有堵塞、漏气现象。

Fault cause: The pressure adjustment screw of the trailer control valve is too loose, causing the pressure of the trailer air reservoir to be too low, or there is blockage or air leakage in the pipeline.

扫除故障：先检查挂车贮气筒压缩空气压力是否符合标准，再检查各管路有无堵塞或漏气现象，若有应实时排除。

Troubleshooting: First, check if the compressed air pressure in the trailer air storage tank meets the standard, and then check if there are any blockages or leaks in each pipeline. If there are any, they should be eliminated in real time.

3、挂车刹车发咬

3. Trailer brake bite

故障原因：挂车控制阀调节螺钉拧得过紧，使挂车贮气筒压力过高，如果加上主车过多地使用制动、气喇叭、气动雨刮等用气设备，压缩空气难以立即补足，造成主车刹不住，挂车刹得死，使挂车轮胎严重磨损，以致迅速报废。

Reason for fault: The adjustment screw of the trailer control valve is tightened too tightly, causing the pressure of the trailer's air reservoir to be too high. If the main vehicle uses too much braking, air horns, pneumatic wipers, and other air consuming equipment, it is difficult to immediately replenish the compressed air, causing the main vehicle to fail to brake and the trailer to brake, causing severe wear and tear on the trailer tires, leading to rapid scrapping.

扫除故障：及时进行正确调整。除此之外，自上料水泥搅拌车分配阀的进气如有漏气现象，即使主车不制动，挂车也自发制动而发咬，应及时检查更换分配阀的进气阀。

Troubleshooting: Make timely and correct adjustments. In addition, if there is air leakage in the intake valve of the self feeding cement mixer truck, even if the main vehicle does not brake, the trailer will automatically brake and bite. The intake valve of the distribution valve should be checked and replaced in a timely manner.

4、挂车制动作用缓慢

4. Slow braking effect of trailer

故障原因：挂车制动时刻若是过晚，也会延长制动距离扫除故障：及时对挂车控制阀和分配阀进行调整，疏通堵塞的管路。

Fault cause: If the trailer braking time is too late, it will also extend the braking distance. Troubleshooting: Adjust the trailer control valve and distribution valve in a timely manner, and clear the blocked pipeline.
