All systems of the automatic concrete loading mixer are normal, but they can not be started. What's the reason? Next, we'll talk about the key points of diagnosis.

1.確定堵塞的原因。為了解決這種混凝土自動(dòng)上料混凝土攪拌車(chē)不會(huì)引起這種故障的診斷，必須首先對(duì)電池進(jìn)行測(cè)試。您需要知道電池電量是否不足。

1. Determine the cause of the blockage. In order to solve this problem, the battery must be tested first. You need to know if the battery is low.

2.檢測(cè)并引導(dǎo)系統(tǒng)。檢測(cè)啟動(dòng)系統(tǒng)的電路。對(duì)于基本配置，用于啟動(dòng)系統(tǒng)的電路通常包括電池，啟動(dòng)馬達(dá)和連接這些組件的電纜。此外，焚燒開(kāi)關(guān)，啟動(dòng)繼電器或螺線管以及車(chē)輛防盜系統(tǒng)也是啟動(dòng)系統(tǒng)的重要組成部分。

2. Detect and boot the system. Check the circuit of the starting system. For a basic configuration, the circuit used to start the system usually includes a battery, a starter motor, and cables to connect these components. In addition, incineration switch, starting relay or solenoid and vehicle anti-theft system are also important parts of the starting system.

3.滑動(dòng)現(xiàn)象在焚燒同步帶的檢測(cè)期間發(fā)生，并且不會(huì)產(chǎn)生火花，因此無(wú)法啟動(dòng)。

3. The sliding phenomenon occurs during the detection of the incineration synchronous belt, and there is no spark, so it can not be started.

4.測(cè)試火花質(zhì)量。您可以卸下焚燒線圈并使用電火花探測(cè)器檢測(cè)火花是否正常。

4. Test spark quality. You can remove the incineration coil and use the spark detector to detect whether the spark is normal.

5.測(cè)試燃油系統(tǒng)。燃油系統(tǒng)診斷可分為兩部分：燃油供應(yīng)系統(tǒng)診斷和噴油器回路診斷?？梢酝ㄟ^(guò)測(cè)量燃油流量和壓力來(lái)檢測(cè)燃油供應(yīng)系統(tǒng)。測(cè)量燃油流量的一個(gè)好方法是加載燃油供應(yīng)管線并測(cè)試管線。

5. Test the fuel system. Fuel system diagnosis can be divided into two parts: fuel supply system diagnosis and injector circuit diagnosis. The fuel supply system can be detected by measuring the fuel flow and pressure. A good way to measure fuel flow is to load the fuel supply line and test the line.

6.防盜系統(tǒng)檢測(cè)：防盜系統(tǒng)也出現(xiàn)在一些經(jīng)常被忽視的供油系統(tǒng)中。一些混凝土自動(dòng)上料混凝土攪拌車(chē)制造商在防盜系統(tǒng)數(shù)據(jù)流中包含參數(shù)標(biāo)識(shí)。在許多型號(hào)中，防盜系統(tǒng)模塊未經(jīng)適當(dāng)?shù)某跏蓟捅桓鼡Q。

6. Anti theft system detection: the anti-theft system also appears in some oil supply systems which are often ignored. Some automatic concrete loading truck manufacturers include parameter identification in the anti-theft system data stream. In many models, the anti-theft system module is replaced without proper initialization.

當(dāng)然，未提及的其他方面也會(huì)對(duì)其產(chǎn)生影響。

Of course, other aspects not mentioned will also affect it.
