自动上料搅拌车驱动装置是否可靠是使用中需高度重视的问题。为保证它的驱动装置完好可靠，应做好以下维护工作：

Whether the driving device of the automatic feeding mixer is reliable or not is a problem that needs high attention in use. In order to ensure that its driving device is intact and reliable, the following maintenance work should be done well:

驱动装置的作用是驱动混凝土贮罐转动，它由取力器、万向轴、液压泵、液压马达、操纵阀、液压油箱及冷却装置组成。如果这部分因故障停止工作，混凝土贮罐将不能转动，这会导致车内混凝土报废，严重的甚使整罐混凝土凝结在罐内，造成混凝土搅拌运输车报废。

The driving device is used to drive the concrete storage tank to rotate. It is composed of power takeoff, universal shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling device. If this part stops working due to failure, the concrete storage tank will not be able to rotate, which will lead to the scrapping of the concrete in the vehicle, and even cause the whole tank of concrete to condense in the tank, resulting in the scrapping of the concrete mixer truck.

1、万向转动部分是故障多发部位，应按时加注润滑脂，并经常检查磨损情况，及时修理更换。车队应有备用的万向轴总成，以保证一旦发生故障能在几十分钟内恢复工作。

1. The universal rotating part is the part with frequent faults, which shall be filled with lubricating grease on time, and the wear condition shall be checked frequently, and the parts shall be repaired and replaced in time. The motorcade shall have a spare cardan shaft assembly to ensure that it can resume operation within tens of minutes in case of failure.

2、保证液压油清洁。混凝土搅拌运输车工作环境恶劣，一定要防止污水泥沙进入液压系统。液压油要按使用手册要求定期更换。一旦检查时发现液压油中混入水或泥沙，就要立即停机清洗液压系统、更换液压油。

2. Ensure that the hydraulic oil is clean. The working environment of the concrete mixer truck is bad, so the dirty cement sand must be prevented from entering the hydraulic system. The hydraulic oil shall be replaced regularly according to the requirements of the user manual. Once water or sediment is found in the hydraulic oil during inspection, stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.

3、保证液压油冷却装置有效。要定时清理液压油散热器，避免散热器被水泥堵塞，检查散热器电动风扇运转是否正常，防止液压油温度超标。液压部分只要保证液压油清洁，一般故障不多；但生产厂家不同，使用寿命则不一样。

3. Ensure that the hydraulic oil cooling device is effective. Clean the hydraulic oil radiator regularly to prevent the radiator from being blocked by cement. Check whether the radiator electric fan operates normally to prevent the hydraulic oil temperature from exceeding the standard. As long as the hydraulic oil is clean, there are few faults in the hydraulic part; However, the service life varies from manufacturer to manufacturer.

此外要知道自动上料搅拌车在运输过程中会始终保持搅拌筒转动，以保证所运载的混凝土不会凝固。运送完混凝土后，通常都会用水冲洗搅拌筒内部，防止硬化的混凝土占用空间。关注我们http://www.jfhntjbj.com，带您了解更多相关事项！

In addition, it should be known that the automatic feeding mixer will always keep the mixing drum rotating during transportation to ensure that the concrete carried will not solidify. After the concrete is transported, the inside of the mixing drum is usually flushed with water to prevent the hardened concrete from occupying space.
