Everyone knows about the mixer truck, but today we're going to talk about its maintenance drive.

驱动单元用于驱动混凝土储罐的旋转。它由输出设备，万向轴，液压泵，液压马达，控制阀，液压油箱和冷却系统组成。

The driving unit is used to drive the rotation of the concrete storage tank. It consists of output equipment, cardan shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling system.

如果某个组件由于故障而失效，则混凝土储罐将无法旋转，车辆内部的混凝土将被刮碎，并且储罐内部的所有混凝土都会凝结成自动废物供应搅拌机。

If a component fails due to a failure, the concrete tank will not rotate, the concrete inside the vehicle will be scraped, and all the concrete inside the tank will condense into an automatic waste supply mixer.

因此，驱动器的可靠性是使用时需要注意的问题。为确保驱动器处于良好状态，您需要执行以下维护任务：

Therefore, the reliability of the drive is a problem that should be paid attention to when using. To ensure that the drive is in good condition, you need to perform the following maintenance tasks:

万向旋转部件是有缺陷的部件。应及时补充润滑脂，并应经常检查磨损状况，并及时修理和更换。团队应该有备用的万向轴组件，一旦发生故障，可以在数分钟内恢复。

Universal rotating parts are defective parts. The lubricating grease shall be supplemented in time, and the wear condition shall be checked frequently, and the lubricating grease shall be repaired and replaced in time. The team should have a spare cardan shaft assembly that can be recovered in a few minutes in case of failure.

确保液压油清洁。全自动给料搅拌机的工作环境很差，必须将脏的水泥砂排除在液压系统之外。应根据手册要求定期更换液压油。如果检查发现液压油中有水或沙子，则应立即关闭液压系统，并更换液压油。

Make sure the hydraulic oil is clean. The working environment of the automatic feeding mixer is very poor, so the dirty cement sand must be excluded from the hydraulic system. The hydraulic oil should be changed regularly according to the manual. If water or sand is found in the hydraulic oil, shut down the hydraulic system immediately and replace the hydraulic oil.

确保液压油冷却系统有效。定期清洁液压油散热器，以防止其被水泥堵塞，确保散热器的电风扇正常工作，并确保液压油温度不超过正常温度。只要液压元件保持液压油清洁，故障通常很少发生，但其寿命因制造商而异。

Ensure that the hydraulic oil cooling system is effective. Regularly clean the hydraulic oil radiator to prevent it from being blocked by cement, ensure that the electric fan of the radiator works normally, and ensure that the hydraulic oil temperature does not exceed the normal temperature. As long as the hydraulic components keep the hydraulic oil clean, faults are usually rare, but their life varies from manufacturer to manufacturer.
