When using the concrete mixer, it is inevitable that the water tank will not rotate. What causes this? What part do I need to check? Now let's talk about it.

1.发动机故障（并非不可能，隆隆声）。

1. Engine failure (not impossible, rumbling).

2.检查液压油是否泄漏（如果管道破裂，请更换管道，如果管道破裂，请更换密封件）。

2. Check whether the hydraulic oil leaks (if the pipe is broken, replace the pipe, if the pipe is broken, replace the seal).

3.混凝土搅拌机的散热器风扇旋转，液压油未乳化或变白，液压油温度超过90度，或液压系统无压力。确保水箱没有旋转（在这种情况下，请用水）。它可以冷却液压泵，液压马达和液压油的温度并旋转油箱。材料并迅速修理散热器或更换液压油。

3. The radiator fan of the concrete mixer rotates, the hydraulic oil does not emulsify or turn white, the temperature of the hydraulic oil exceeds 90 degrees, or the hydraulic system has no pressure. Make sure that the tank does not rotate (in this case, use water). It can cool the temperature of hydraulic pump, hydraulic motor and hydraulic oil and rotate the oil tank. Remove the material and quickly repair the radiator or replace the hydraulic oil.

4.传动轴的10齿损坏或损坏（a：如果损坏，请立即更换传动轴。B.传动轴是否良好）。

4. The 10 teeth of the transmission shaft are damaged or damaged (A: if damaged, please replace the transmission shaft immediately. B. Whether the transmission shaft is in good condition).

5.运输过程中我很小心，水箱停了下来！混凝土坍塌，水箱无法翻转（这是您感到有点旋转的压力时）。

5. I was very careful during the transportation, the water tank stopped! The concrete collapses and the water tank cannot be turned over (this is when you feel a bit of rotational pressure).

6.液压泵损坏（情况稍微复杂一些，内部腹泻严重，还有其他损坏）。

6. The hydraulic pump is damaged (the situation is a little more complicated, the internal diarrhea is serious, and there are other damages).

如果发生以上六种情况，混凝土不凝结，液压马达和减速器未发生故障，可以使用应急装置。使用另一台多功能混凝土运输搅拌机的液压泵驱动液压马达旋转水箱，释放混凝土，然后进行检查和维修。

If the above six conditions occur, the concrete does not set, and the hydraulic motor and reducer do not fail, the emergency device can be used. Use the hydraulic pump of another multifunctional concrete transport mixer to drive the hydraulic motor to rotate the water tank, release the concrete, and then carry out inspection and maintenance.

混凝土搅拌机的零件，无需旋转即可检查，时常检验机器有助于提高工作效率！

The parts of concrete mixer can be inspected without rotation. It is helpful to improve work efficiency to inspect the machine from time to time!
