1.它由动力输出装置，万向轴，液压泵，液压马达，控制阀，液压油箱和冷却系统组成普通车削零件是有缺陷的零件。润滑脂应按时加注，应经常检查磨损并及时修理和更换。团队必须有一个备用的万向轴组件，以便万一发生故障，几分钟之内即可将其恢复。
1. It consists of power take-off, cardan shaft, hydraulic pump, hydraulic motor, control valve, hydraulic oil tank and cooling system. Ordinary turning parts are defective parts. The grease should be filled on time, the wear should be checked frequently, and the grease should be repaired and replaced in time. The team must have a spare cardan shaft assembly so that it can be restored in 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不好，必须防止脏的水泥砂进入液压系统。应根据手册的要求定期更换液压油。如果检查发现液压油被水或沙子污染，则应立即停止液压系统并更换液压油。
2. Make sure the hydraulic oil is clean. The working environment of concrete mixer is not good, so it is necessary to prevent the dirty cement sａnd from entering the hydraulic system. The hydraulic oil should be changed regularly according to the manual. If it is found that the hydraulic oil is polluted by water or sand, stop the hydraulic system immediately and replace the hydraulic oil.
3.确保启用了液压油冷却器。定期清洁液压散热器，以防止其被水泥堵塞，并确保散热器风扇正常工作，并且液压温度不超过正常温度。只要保证液压部件能够清洁液压油，通常故障很少，但是制造商具有不同的使用寿命。
3. Make sure that the hydraulic oil cooler is activated. Regularly clean the hydraulic radiator to prevent it from being blocked by cement, and ensure that the radiator fan works normally, and the hydraulic temperature does not exceed the normal temperature. As long as the hydraulic components can clean the hydraulic oil, there are usually few failures, but the manufacturers have different service life.
