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

首先，轉(zhuǎn)向器助力泵不吸油，或者油壓太小。

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

問題原因：

Cause of problem:

1.由于橡膠的耐蝕性，濾芯被堵塞，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.管接頭處漏氣，空氣進(jìn)入。

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

3.動(dòng)力泵零件磨損，間隙過大，導(dǎo)致機(jī)油稀薄。

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

4，機(jī)油不符合要求或使用時(shí)間過長(zhǎng)，粘度過大，葉片滑動(dòng)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.儲(chǔ)油罐中的油位過低。

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

排除方法：

Troubleshooting:

1.用酒精清潔濾芯，更換油管，然后在指定位置添加液壓油。

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

2.檢查連接牢固，以防止空氣進(jìn)入。

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

3.檢查并修理增壓泵，以更換磨損的零件。

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

其次，轉(zhuǎn)向器動(dòng)力泵的工作量太大。

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

故障原因：空氣進(jìn)入，安全閥損壞或壓力過高，吸油阻力過大。

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.檢查接頭的密封性，以防止空氣進(jìn)入。

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

2.修理安全閥。

2. Repair the safety valve.

3.更換進(jìn)油管。

3. Replace the oil inlet pipe.
