Concrete mixer as the most important part of the mixing plant, the user is also very cautious in the selection, but sometimes in the use process or can not get rid of the problem of failure.

　　混凝土搅拌机常见的故障有：

　　The common faults of concrete mixer are as follows:

　　1.由于联接螺栓松动衬板不齐造成搅拌叶片、支撑臂衬板松动。

　　1. The lining plate of mixing blade and support arm is loose due to loose connecting bolts and uneven lining plate.

　　2.圆锥滚子轴承损坏，造成卷扬减速器嗓声异常。

　　2. The tapered roller bearing is damaged, resulting in abnormal noise of the winch reducer.

　　3.搅拌桶内有石子卡住搅拌叶片导致搅拌电机停止运转。

　　3. There are stones in the mixing bucket that block the mixing blade, which causes the mixing motor to stop running.
         

　　4.搅拌叶片磨损严重，没有及时更换，造成间隙太大，石子卡塞过载，搅拌轴端支承装置阻力太大，电压偏低造成搅拌电机过热。

　　4. The mixing blade was seriously worn and not replaced in time, resulting in too large clearance, stone jam overload, high resistance of the support device at the end of the mixing shaft, and low voltage, resulting in the overheating of the mixing motor.

　　5.轨道安装不平行或者点击制动器分离间隙过小，电压偏低，使得卷扬电机过热。

　　5. The track installation is not parallel or the clearance between the click brake is too small and the voltage is too low, which makes the winch motor overheat.

　　6.故障指示灯灭可能是因为料斗上升个限位开关坏了或者是摇臂松动，撞针锈蚀，橡胶护套破损等等。

　　6. The failure indicator light may be off because the first limit switch is broken when the hopper rises, or the rocker arm is loose, the impact pin is rusty, and the rubber sheath is damaged.

　　以上故障常用的排除方法有：

　　The common troubleshooting methods are as follows:

　　1.可以在使用前日常检查时紧固联结螺栓调平衬板。

　　1. The coupling bolts can be tightened and the lining plate can be leveled during daily inspection before use.

　　2.更换轴承。

　　2. Replace the bearing.

　　3.排除搅拌叶片与陈衬板间卡住的石子。

　　3. Remove the stones stuck between the mixing blade and the old lining plate.

　　4.更换叶片，调好间隙；在搅拌支承装置加注润滑脂。

　　4. Replace the blade and adjust the clearance; add grease to the mixing support device.

　　5.调整轨道平行度，调整电机制动分离间隙。

　　5. Adjust Track parallelism and motor brake separation clearance.

　　6.修复或更换新的限位开关。

　　6. Repair or replace the limit switch.
