1、分配閥活塞漏氣
1. Distribution valve piston leaking
故障原因：當踩下
自上料水泥攪拌車的制動踏板時，大量壓縮空氣從掛車控制閥漏出，很快將掛車貯氣筒內的壓縮空氣漏完，失去制動作用。
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.
掃除故障：將分配閥拆下檢查，若是磨損、破裂應實時更換。
Troubleshooting: Remove the distribution valve for inspection, and replace it in real time if it is worn or broken.
2、掛車剎車不靈
2. Trailer brake not working properly
故障原因：掛車控制閥的壓力調節(jié)螺釘擰得過松，使掛車貯氣筒壓力過低、或管路中有堵塞、漏氣現(xiàn)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.
掃除故障：先檢查掛車貯氣筒壓縮空氣壓力是否符合標準，再檢查各管路有無堵塞或漏氣現(xiàn)象，若有應實時排除。
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、掛車剎車發(fā)咬
3. Trailer brake bite
故障原因：掛車控制閥調節(jié)螺釘擰得過緊，使掛車貯氣筒壓力過高，如果加上主車過多地使用制動、氣喇叭、氣動雨刮等用氣設備，壓縮空氣難以立即補足，造成主車剎不住，掛車剎得死，使掛車輪胎嚴重磨損，以致迅速報廢。
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.
掃除故障：及時進行正確調整。除此之外，自上料水泥攪拌車分配閥的進氣如有漏氣現(xiàn)象，即使主車不制動，掛車也自發(fā)制動而發(fā)咬，應及時檢查更換分配閥的進氣閥。
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、掛車制動作用緩慢
4. Slow braking effect of trailer
故障原因：掛車制動時刻若是過晚，也會延長制動距離掃除故障：及時對掛車控制閥和分配閥進行調整，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.
