自动上料搅拌车的装料卸料主要是靠液压系统来实现的，液压系统一旦出故障，整个搅拌车都不能正常工作了。下面来讲讲搅拌车液压系统出问题的六个表现以及有什么办法。

The loading and unloading of the automatic feeding mixer is mainly realized by the hydraulic system. Once the hydraulic system fails, the entire mixer cannot work normally. Now let's talk about the six symptoms of problems in the hydraulic system of the mixer and the solutions.

1.搅拌罐不能转动：

1. The mixing tank cannot rotate:

a.无补液压油：检查补油泵及油箱；b.补油压力过低：检查油压，将补油压力调14-18兆帕；c.检查油箱油位是否满足液压系统工作：油位不足需及时补充同企业同型号的油液；d.连接盘花键套内花键损坏：更换连接盘或主泵通轴；e.吸油管路断裂、被挤压：更换或修理吸油管路；f.排量控制线脱开：连接好排量控制线；g伺服阀、销损坏：更换伺服阀、销；h.控制油路被异物堵塞：清洗油路；i.滤油器太脏：清洗或更换滤油器。

a. No hydraulic oil replenishing: check the oil replenishing pump and oil tank; b. Too low make-up pressure: check the oil pressure and adjust the make-up pressure to 14-18 MPa; c. Check whether the oil level in the oil tank meets the requirements of the hydraulic system: if the oil level is insufficient, the oil of the same brand and model shall be replenished in time; d. The spline inside the connecting disc spline sleeve is damaged: replace the connecting disc or the main pump shaft; e. Broken or squeezed oil suction pipeline: replace or repair the oil suction pipeline; f. Discharge control line is disconnected: connect the discharge control line; G Damaged servo valve and safety pin: replace the servo valve and safety pin; h. The control oil circuit is blocked by foreign matters: clean the oil circuit; i. The oil filter is too dirty: clean or replace the oil filter.

2.搅拌罐启动慢：

2. Slow startup of mixing tank:

a.滤芯损坏或太脏：清洗或更换滤芯；b.油路连接松动或密封件损坏：拧紧或更换密封；c.油箱油位不足，及时补足油量；e.控制软轴损坏：更换软轴。

a. Damaged or dirty filter element: clean or replace the filter element; b. Loose oil circuit connection or damaged seal: tighten or replace the seal; c. If the oil level in the oil tank is insufficient, replenish the oil in time; e. Damaged control flexible shaft: replace the flexible shaft.

3.工作时有噪音：

3. Noise during operation:

a.吸油路漏气：拧紧或更换密封件；b.油的标号不配：更换合适的标号液压油；c.泵与马达、万向轴等的连接松动：紧固连接螺栓；d.油箱油量过少：给油箱补油。

a. Air leakage of oil suction circuit: tighten or replace the seal; b. Improper oil grade: replace the hydraulic oil with proper grade; c. Loose connection between pump and motor, cardan shaft, etc.: tighten the connecting bolts; d. Too little oil in the oil tank: refill the oil tank.

4.油温过高：

4. The oil temperature is too high:

a.液压油标号不对：更换合适标号的液压油；b.液压油脏活液压系统超负荷工作：更换液压油或调整负荷；c.冷却风扇不转，油温器损坏：更换油温器；d.冷却器过油量不够：及时补油；e.液压件内泄严重：更换有关零部件；f.滤油器脏活损坏：清洗或更换滤油器。

a. Incorrect hydraulic oil grade: replace the hydraulic oil with proper grade; b. The hydraulic oil is dirty and the hydraulic system is overloaded: replace the hydraulic oil or adjust the load; c. The cooling fan does not rotate and the oil temperature sensor is damaged: replace the oil temperature sensor; d. Insufficient oil passing through the cooler: replenish oil in time; e. Serious internal leakage of hydraulic parts: replace relevant parts; f. The oil filter is dirty and damaged: clean or replace the oil filter.

5.搅拌罐转速不快（工作无力）：

5. The speed of the mixing tank is not fast (unable to work):

a.辅助泵溢流压力过低：调整溢流压力；b.辅助泵损坏：更换辅助泵。

a. The overflow pressure of the auxiliary pump is too low: adjust the overflow pressure; b. Damaged auxiliary pump: replace the auxiliary pump.

6.轴封漏油：

6. Oil leakage of shaft seal:

a.油封老化：更换新油封；b.花键连接盘轴向未定，其端面与油封摩擦：更换连接盘。

a. Oil seal aging: replace it with a new one; b. The axial direction of the splined connecting disc is uncertain, and its end face rubs against the oil seal: replace the connecting disc.
