全自动搅拌车拌筒停转故障的分析
全自动搅拌车厂家根据全自动搅拌车的特点，发生拌筒不旋转、无法排出砼的故障，主要是由以下几种原因造成的：
According to the characteristics of the fully automatic mixer, the manufacturer of the fully automatic mixer has the failure that the mixing drum does not rotate and the concrete cannot be discharged, which is mainly caused by the following reasons:
①减速机发生故障；②液压马达发生故障；③发动机或液压油泵发生故障。根据我公司的售后服务情况来看，拌筒不旋转、排不出砼的故障是少出现的。许多用户由于没有经验，遇到类似情况往往不知如何处理，容易造成不必要的损失。主要介绍如何正确处置这类故障。
① The reducer fails; ② The hydraulic motor fails; ③ The engine or the hydraulic oil pump has failed. According to the after-sales service of our company, the failure that the mixing drum does not rotate and cannot discharge concrete is rare. Because many users have no experience, they often do not know how to deal with similar situations, which is easy to cause unnecessary losses. This paper mainly introduces how to correctly handle such failures.
如果只有单台搅拌车在现场作业，没有其他相同配置的车辆，或是没有备有应急管，不论是何种原因造成的拌筒停转故障，都只能采取人工的方法排出砼。具体操作方法：
If only a single mixer truck is working on the site, there is no other vehicle with the same configuration, or there is no emergency pipe, no matter what reason the mixer drum stops running, the concrete can only be discharged manually. Specific operation method:
将操作手柄转到中位，使液压油泵不能再产生高压油；将发动机熄火，在确保液压系统已经卸压的情况下旋松马达或减速机上的高压油管，推动拌筒旋转，使拌筒检修孔斜向下；
Turn the operating handle to the middle position, so that the hydraulic oil pump can no longer produce high-pressure oil; Turn off the engine, unscrew the high-pressure oil pipe on the motor or reducer under the condition that the hydraulic system has been depressurized, and push the mixing drum to rotate so that the mixing drum manhole is inclined downward;
打开搅拌筒检修孔盖，将砼从搅拌筒检修孔用人工的方法排出。旋松高压油管及清理砼时在托轮和拌筒滚道间放入木楔，确保搅拌筒不能转动，否则拌筒可能因筒体内砼位置变化造成突然转动而产生危险。
Open the manhole cover of the mixing drum and discharge the concrete from the manhole of the mixing drum manually. When loosening the high-pressure oil pipe and cleaning the concrete, put wooden wedges between the supporting wheel and the mixing drum raceway to ensure that the mixing drum cannot rotate, otherwise the mixing drum may rotate suddenly due to the change of the concrete gravity center position in the drum, which may cause danger.
若用户使用相同液压配置的搅拌车在2台以上，并备有应急管，采取何种方法排出砼，应视具体情况而定：
If the user uses more than 2 mixers with the same hydraulic configuration and is equipped with emergency pipes, the method to discharge concrete shall be determined according to the specific situation:
①若是减速机发生了故障，则只能采用人工方法排出砼，方法同前；
① If the reducer fails, the concrete can only be discharged manually, the method is the same as before;
②若是马达发生了故障，可将其他车上马达卸下，替换故障车上的马达并按原来的油管联接位置接好，启动发动机使油泵工作，即可操纵手柄排出砼；
② If the motor fails, remove the other motor on the vehicle, replace the motor on the failed vehicle and connect it according to the original oil pipe connection position. Start the engine to make the oil pump work, and then the handle can discharge the concrete;
③若是发动机不能启动，应先判断如能重新将发动机启动起来，并可以工作一定的时间，则先将发动机启动，排出砼后再进行故障的检修。
③ If the engine cannot be started, it should be judged first that if the engine can be restarted and can work for a certain period of time, the engine should be started first, and the troubleshooting should be carried out after the concrete is discharged.
在实际运用中，由于每一个用户对自动上料搅拌车所掌握的情况不同，因此需视具体情况参照以上的方法进行操作，以快速度排出砼，以免延误时间，造成不必要的损失。更多相关事项就来我们网站https://www.jfjiaobanche.com咨询吧！
In practical application, because each user has different information about the automatic feeding mixer, it is necessary to refer to the above methods according to the specific situation, and discharge the concrete at a fast speed, so as to avoid delay and unnecessary loss.
