Causes and solutions of steering pump failure of automatic concrete mixer:

，转向器助力泵不吸油，或者油压太小。

First, the steering gear booster pump does not absorb oil, or the oil pressure is too small.

问题原因：

Cause of problem:

1.由于橡胶的耐蚀性，滤芯被堵塞，油管也被堵塞。

1. Due to the corrosion resistance of rubber, the filter element is blocked and the oil pipe is also blocked.

2.管接头处漏气，空气进入。

2. Air leaks at the pipe joint and air enters.

3.动力泵零件磨损，间隙过大，导致机油稀薄。

3. The parts of the power pump are worn and the clearance is too large, resulting in thin oil.

4，机油不符合要求或使用时间过长，粘度过大，叶片滑动阻力大。

4. The oil does not meet the requirements or the service time is too long, the viscosity is too large, and the blade sliding resistance is large.

5.储油罐中的油位过低。

5. The oil level in the oil storage tank is too low.

排除方法：

Troubleshooting:

1.用酒精清洁滤芯，更换油管，然后在指定位置添加液压油。

1. Clean the filter element with alcohol, replace the oil pipe, and then add hydraulic oil at the specified position.

2.检查连接牢固，以防止空气进入。

2. Check that the connection is firm to prevent air from entering.

3.检查并修理增压泵，以更换磨损的零件。

3. Check and repair booster pump to replace worn parts.

其次，转向器动力泵的工作量太大。

Secondly, the workload of the steering gear power pump is too large.

故障原因：空气进入，阀损坏或压力过高，吸油阻力过大。

Fault cause: air enters, the safety valve is damaged or the pressure is too high, and the oil suction resistance is too large.

排除方法：

Troubleshooting:

1.检查接头的密封性，以防止空气进入。

1. Check the tightness of the joint to prevent air from entering.

2.修理阀。

2. Repair the safety valve.

3.更换进油管。

3. Replace the oil inlet pipe.
