自动上料搅拌车的出现和使用，能够为各类工程施工提供了诸多的便利，这些都是自动上料搅拌车的功劳，在使用的程度上提升了该设备的作业效率。使用人员要想保障自动上料搅拌车的使用性能，其中，一个重要的配件就是变速器换挡机，每一种配件使用时间长了，都会出现一些问题，在它损坏后如何进行维修呢？

The emergence and use of automatic feeding mixer trucks have provided many conveniences for various engineering construction projects, all of which are attributed to the use of automatic feeding mixer trucks and have improved the operational efficiency of the equipment to a certain extent. To ensure the performance of the automatic feeding mixer truck, one important accessory is the transmission shifter. Each accessory may have some problems after being used for a long time. How to repair it after it is damaged?

一，液压系统或发动机故障的处理：

1、 Handling of hydraulic system or engine malfunctions:

（1）打开自动上料搅拌车混合管检查孔盖，松开电机上高压软管的管接头，旋转搅拌筒，使搅拌筒的混合孔向下倾斜，排出混凝土搅拌筒的混合孔;

(1) Open the inspection hole cover of the mixing pipe of the automatic feeding mixer truck, loosen the pipe joint of the high-pressure hose on the motor, rotate the mixing drum, tilt the mixing hole of the mixing drum downwards, and discharge the mixing hole of the concrete mixing drum;

（2）从电机上拆下故障车辆的高压软管，连接高压软管进行救援，将另一端连接到救援车的油泵，并将应急回油管的末端连接到故障车辆的电动机。回油管的另一端连接到救援车的油泵返回口，救援车用于控制故障车混合滚筒的旋转。

(2) Remove the high-pressure hose of the faulty vehicle from the motor, connect the high-pressure hose for rescue, connect the other end to the oil pump of the rescue vehicle, and connect the end of the emergency return pipe to the motor of the faulty vehicle. The other end of the oil return pipe is connected to the oil pump return port of the rescue vehicle, which is used to control the rotation of the mixing drum of the faulty vehicle.

我们的现场测试发现，对于生产工厂中的所有工具，使用方法二大约需要1小时。如果施工现场的时间可能更长，建议使用方法一排出坩埚。

Our on-site testing found that for all tools in the production factory, using Method 2 takes approximately 1 hour. If the construction site time may be longer, it is recommended to use Method 1 to discharge the crucible.

二，电机故障：操作相对简单，救援车的电机可以拆除故障车，然后将各种油管连接起来，启动救援车可以将混合鼓内的痰液排出。

2、 Motor failure: The operation is relatively simple. The motor of the rescue vehicle can be removed from the faulty vehicle, and various oil pipes can be connected. Starting the rescue vehicle can discharge the phlegm in the mixed drum.

当搅拌车启动困难或不能启动时，主要症状可能有以下原因：

When the mixer truck is difficult or unable to start, the main symptoms may include the following reasons:

（1）起动机的发动机均有正常转速，但不着火，或经长时间启动方可着火。

(1) The engine of the starter has normal speed, but it does not ignite or can only ignite after a long time of starting.

（2）电气系统有故障，主要是蓄电池电压过低造成启动不着火。

(2) There is a malfunction in the electrical system, mainly due to the low battery voltage causing the ignition to fail during startup.

（3）进气系统有故障，主要是进气阻力超过了技术规范，导致启动困难或不着火不能启动。

(3) There is a malfunction in the intake system, mainly due to the intake resistance exceeding the technical specifications, resulting in difficulty in starting or failure to start due to misfire.

（4）曲轴不转，可能为抱轴、咬缸，或其他不正常的情况，均可导致启动困难或不能启动。除此之外，有时候由于油箱内油面过低，也能导致出现启动困难或不能启动的现象。

(4) If the crankshaft does not rotate, it may be due to holding the shaft, biting the cylinder, or other abnormal situations, which can cause difficulty or inability to start. In addition, sometimes due to the low oil level in the fuel tank, it can also lead to difficulties or inability to start.

简而言之，对于自动上料搅拌车，当发生故障时，应及时判断故障原因，并在故障之前采取有效措施排出自动上料搅拌车中的缺陷。更多相关内容就来我们网站http://www.zkzsljbc.com进行咨询了解吧！
