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上料混凝土攪拌車不會引起這種故障的診斷，必須首先對電池進行測試。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.檢測并引導系統(tǒng)。檢測啟動系統(tǒng)的電路。對于基本配置，用于啟動系統(tǒng)的電路通常包括電池，啟動馬達和連接這些組件的電纜。此外，焚燒開關，啟動繼電器或螺線管以及車輛防盜系統(tǒng)也是啟動系統(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.滑動現(xiàn)象在焚燒同步帶的檢測期間發(fā)生，并且不會產(chǎn)生火花，因此無法啟動。

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

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

5.測試燃油系統(tǒng)。燃油系統(tǒng)診斷可分為兩部分：燃油供應系統(tǒng)診斷和噴油器回路診斷。可以通過測量燃油流量和壓力來檢測燃油供應系統(tǒng)。測量燃油流量的一個好方法是加載燃油供應管線并測試管線。

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：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。一些混凝土自動上料混凝土攪拌車制造商在防盜系統(tǒng)數(shù)據(jù)流中包含參數(shù)標識。在許多型號中，防盜系統(tǒng)模塊未經(jīng)適當?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.

當然，未提及的其他方面也會對其產(chǎn)生影響。

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