The function of the driver is to drive the rotation of the concrete storage tank, which is composed of power take-off, cardan shaft, hydraulic pump, hydraulic motor, control valve, hydraulic tank and cooling device. Terminal. For the automatic concrete mixer, the driving force is still very important, so let's take a closer look below.

1.通用旋转零件是有很多故障的零件。应及时添加油脂，经常检查磨损，并及时修理和更换。团队应该准备备用万向轴组件，以备万一发生故障时在数十分钟内恢复工作。

1. General rotating parts are parts with many faults. Grease should be added in time, wear should be checked frequently, and repaired and replaced in time. The team should have a spare cardan shaft assembly ready to return to work within a few minutes in case of failure.

2.确保液压油清洁。混凝土搅拌车的工作环境恶劣，必 须将肮脏的水泥砂排除在液压系统之外。应根据用户手册的要求定期更换液压油。如果在检查过程中发现液压油中混有水或沙，则应立即停止机器以清洁液压系统，并应更换液压油。

2. Make sure the hydraulic oil is clean. The working environment of concrete mixer is bad, so the dirty cement sand must be excluded from the hydraulic system. The hydraulic oil should be changed regularly according to the requirements of the user manual. If water or sand is found in the hydraulic oil during the inspection, stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.

3.确保启用了液压油冷却器。应当定期清洁液压油，以防止散热器被水泥堵塞，以确保散热器风扇正常工作，并且液压油的温度不超过正常温度。如果液压油是干净的，则液压油的故障很少，但是寿命会因制造商而异。

3. Make sure that the hydraulic oil cooler is activated. The hydraulic oil should be cleaned regularly to prevent the radiator from being blocked by cement to ensure that the radiator fan works normally and the temperature of the hydraulic oil does not exceed the normal temperature. If the hydraulic oil is clean, the hydraulic oil has few faults, but the service life will vary from manufacturer to manufacturer.

通常，如果驱动单元由于故障而失效，则混凝土储罐将无法 正常旋转，车辆中的混凝土将被丢弃，整个混凝土罐将凝结。混凝土全自动搅拌车要丢弃。因此，驱动器的可靠性是使用时需要注意的一个问题。

In general, if the drive unit fails due to failure, the concrete tank will not rotate normally, the concrete in the vehicle will be discarded, and the whole concrete tank will set. The automatic concrete mixer should be discarded. Therefore, the reliability of the drive is a problem that should be paid attention to when using.
