First of all, the steering gear booster pump is not sucking oil or the oil pressure is too low.

问题原因：

Cause of the problem:

1.由于橡胶的耐腐蚀性，滤芯堵塞，管子堵塞。

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

2.管接头漏气，空气进入。

2. The pipe joint leaks air and air enters.

3.机油稀薄，因为动力泵的零件已磨损且间隙过大。

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

4.机油不符合要求，使用时间过长，粘度过高，刀片具有较高的防滑性。

4. The engine oil does not meet the requirements, the service time is too long, the viscosity is too high, and the blade has high skid resistance.

5.储油罐中的油位过低。

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

方法：

Cleaning method:

1.用酒精清洁滤芯，更换油管，并在指定位置添加液压油。

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

2.确保已牢固连接以防止空气进入。

2. Make sure it is firmly connected to prevent air from entering.

3.检查并修理增压泵，并更换磨损的零件。

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

其次，转向器动力泵超载。

Secondly, the power pump of the steering gear is overloaded.

故障原因：空气进入，阀损坏，压力过高，吸油阻力过高。

Cause of failure: air enters, safety valve is damaged, pressure is too high, oil absorption resistance is too high.

方法：

Cleaning method:

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。
