The normal work of concrete mixer is driven by the hydraulic system, and the hydraulic pump and hydraulic motor are also very key components in the hydraulic system, especially the hydraulic pump. The following small series will introduce the precautions for the use of its hydraulic pump.

在使用前一定要确认液压泵是否安装到位，螺钉是否拧紧，联轴器安装是否符合要求。然后检查泵体内是否加满符合标号的液压油。再次检查泵的转向是否与进出油口相符，液压系统的阀是否调到规定压力值。

Before use, make sure whether the hydraulic pump is installed in place, whether the screw is tightened, and whether the coupling installation meets the requirements. Then check whether the pump body is filled with hydraulic oil according to the label. Check again whether the steering of the pump is consistent with the oil inlet and outlet, and whether the safety valve of the hydraulic system is adjusted to the specified pressure.
            

在使用混凝土运输搅拌车液压泵时切不可急剧全速启动，应在系统卸荷状态下点动原动机开关数次后才能连续空载运转，目的是将管道中的空气尽可能排除干净，空载运转1~2min无异常现象后逐渐加载，加载过程中应无异常振动、噪声和泄漏，否则立即停机检查分析、排除故障。

When using the hydraulic pump of concrete mixer truck, it is not allowed to start rapidly at full speed. The prime mover switch should be inched several times under the unloading state of the system before continuous no-load operation. The purpose is to remove the air in the pipeline as far as possible. After no-load operation for 1 ~ 2min, there should be no abnormal vibration, noise and leakage. Otherwise, it should be stopped immediately for inspection and analysis Troubleshooting.

在长时间的使用后一定要注意更换液压油，这样才能保证油泵处于好的工作状态。

After a long time of use, we must pay attention to replace the hydraulic oil, so as to ensure that the oil pump is in good working condition.

以上就是混凝土运输搅拌车液压泵使用注意事项，希望大家学会以后以正确的使用液压泵，以免产生不必要的后果。

The above is the concrete transport mixer hydraulic pump use precautions, I hope you learn to use the hydraulic pump correctly in the future, in order to avoid unnecessary consequences.
