此外自上料搅拌车在装料时不要装太满，要预留一些空间让粉粒扩容，要注意在装料时避免一些杂物混入搅拌罐内，因为这样会使卸料管堵塞，影响卸料速度和剩余率。

In addition, the self feeding mixer truck shall not be too full during loading, and some space shall be reserved for powder expansion. Attention shall be paid to prevent some sundries from mixing into the mixing tank during loading, because this will block the discharge pipe and affect the discharge speed and residual rate.

搅拌车在卸料后冲洗车辆时，上下扶梯须抓紧扶手，身体严禁接触转动部位。冲洗完车辆后要将水箱阀门关闭，固定好卸料槽及水管。

When the mixer truck is washing the vehicle after unloading, the handrail must be firmly grasped when getting up and down the escalator, and the body must not touch the rotating parts. After washing the vehicle, close the water tank valve and fix the discharge chute and water pipe.

每天下班后要对车辆做多面检查，发现故障要及时维修。以上就是有关搅拌车卸料门关闭时无信号的检修内容了，希望对您有帮助，更多事项就来我们网站https://www.zishangliaojiaobanji.cn咨询！
