自動上料攪拌車的出現和使用，能夠為各類工程施工提供了諸多的便利，這些都是自動上料攪拌車的功勞，在使用的程度上提升了該設備的作業效率。使用人員要想保障自動上料攪拌車的使用性能，其中，一個重要的配件就是變速器換擋機，每一種配件使用時間長了，都會出現一些問題，在它損壞后如何進行維修呢？

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，液壓系統或發動機故障的處理：

1、 Handling of hydraulic system or engine malfunctions:

（1）打開自動上料攪拌車混合管檢查孔蓋，松開電機上高壓軟管的管接頭，旋轉攪拌筒，使攪拌筒的混合孔向下傾斜，排出混凝土攪拌筒的混合孔;

(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）從電機上拆下故障車輛的高壓軟管，連接高壓軟管進行救援，將另一端連接到救援車的油泵，并將應急回油管的末端連接到故障車輛的電動機。回油管的另一端連接到救援車的油泵返回口，救援車用于控制故障車混合滾筒的旋轉。

(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.

我們的現場測試發現，對于生產工廠中的所有工具，使用方法二大約需要1小時。如果施工現場的時間可能更長，建議使用方法一排出坩堝。

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，電機故障：操作相對簡單，救援車的電機可以拆除故障車，然后將各種油管連接起來，啟動救援車可以將混合鼓內的痰液排出。

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.

當攪拌車啟動困難或不能啟動時，主要癥狀可能有以下原因：

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

（1）起動機的發動機均有正常轉速，但不著火，或經長時間啟動方可著火。

(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）電氣系統有故障，主要是蓄電池電壓過低造成啟動不著火。

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

（3）進氣系統有故障，主要是進氣阻力超過了技術規范，導致啟動困難或不著火不能啟動。

(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）曲軸不轉，可能為抱軸、咬缸，或其他不正常的情況，均可導致啟動困難或不能啟動。除此之外，有時候由于油箱內油面過低，也能導致出現啟動困難或不能啟動的現象。

(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.

簡而言之，對于自動上料攪拌車，當發生故障時，應及時判斷故障原因，并在解決故障之前采取有效措施排出自動上料攪拌車中的缺陷。更多相關內容就來我們網站http://www.www.boy7up.cn進行咨詢了解吧！
