混凝土搅拌机的喇叭虽然是小部件，但是会时不时的会出现各种问题，属于易损部位。所以使用时一定要谨慎爱护，下面小编就带大家一起看看有哪些原因会导致混凝土搅拌机喇叭出现故障呢？

Although the horn of concrete mixer is a small part, there will be various problems from time to time, belonging to vulnerable parts. Therefore, we must take care of it carefully when using it. The following small series will take you to see what causes the concrete mixer horn to malfunction?

混凝土搅拌机电磁线圈端子接触不良：有些喇叭内部电磁线圈漆包线端子接头是铝金属铆钉压接连接的，非牢靠焊接连接，如果端头漆包线上的绝缘漆处理不净或铆钉压接不牢靠很容易产生虚接故障，导致喇叭工作不良。此种故障是喇叭质量原因，无法修复，只能更换新件。

Poor contact of electromagnetic coil terminal of concrete mixer: the terminal joint of enameled wire of electromagnetic coil inside some horns is crimped with aluminum metal rivets, which is not firmly welded. If the insulating paint on the enameled wire at the end is not treated cleanly or the rivets are not pressed firmly, it is easy to cause false connection fault, which will lead to poor working of the horn. This kind of fault is caused by the quality of the horn, which cannot be repaired and can only be replaced with a new one.

混凝土搅拌机密封不严易受潮：虽然混凝土搅拌机喇叭内部是密闭的，但如果密封不严清洗混凝土搅拌机时进入雾气或内部空间空气中有水蒸气，水蒸气很容易导致触点受潮无法正常工作。

The concrete mixer is not tightly sealed and easy to be affected by damp: Although the inner part of the concrete mixer horn is sealed, if the concrete mixer is not sealed tightly, when cleaning the concrete mixer, it enters into the fog or there is water vapor in the air, and the water vapor is easy to cause the contact point to be affected by moisture and unable to work normally.
             

混凝土搅拌机触点烧蚀：如果长时间按喇叭易造成喇叭触点烧蚀而产生阻抗，流过电磁线圈的电流减弱，混凝土搅拌机电磁吸力下降无法吸引衔铁带动膜片正常振动，导致发音沙哑、甚至不响。但不断按喇叭时，若瞬间强电流通过阻抗依然能正常工作，所以会时好时坏。

Contact ablation of concrete mixer: if the horn is pressed for a long time, the contact of the horn will be ablated and the impedance will be generated. The current flowing through the electromagnetic coil will be weakened, and the electromagnetic suction of the concrete mixer will be reduced, which will not attract the armature to drive the diaphragm to vibrate normally, resulting in hoarseness or even no sound. However, if the horn is constantly honked, if the instantaneous strong current passes through the impedance, it can still work normally, so it will sometimes be good or bad.

解决了以上的喇叭问题，接下来看看闹心的噪音问题吧。虽然都不是大问题，但是都是要上心啊！操作混凝土搅拌机的朋友都知道机器在操作中噪音很大，不知道怎么处理才正确，其实噪音大的综合原因是决定噪音大的主要因素，下面介绍一些噪音的原因以及防治的方法：

After solving the above speaker problem, let's take a look at the noisy problem. Although it's not a big problem, it's all about caring! The friends who operate the concrete mixer all know that the machine is noisy in operation, and they don't know how to deal with it correctly. In fact, the comprehensive reason for the noise is the main factor determining the noise. Here are some reasons for the noise and the prevention and control measures:

1、滤芯堵塞也是会造成噪音大，处理方法是清洗或更换滤芯。

1. Clogging of filter element will also cause high noise, and the treatment method is to clean or replace the filter element.

2、工作的油液不合要求或油液粘度太大也是会造成噪音的，需要更换低粘度的液压油。

2. The working fluid does not meet the requirements or the oil viscosity is too high, it will also cause noise, need to replace the low viscosity hydraulic oil.

3、车油箱液面太低，油面上空气被吸入泵内，补加相同标号的液压油。

3. The oil tank level is too low, the air on the oil level is sucked into the pump, and the hydraulic oil of the same label is added.

4、吸油管路进气或堵塞；检查拧紧，不要吸进空气。

4. The oil suction pipe is air intake or blocked; check and tighten, do not suck in air.

5、泵的安装支架的刚性不足，工作时会产生震动和噪音，加固支架。

5. The rigidity of the pump's mounting bracket is not enough, which will produce vibration and noise when working, so as to strengthen the support.

6、混凝土搅拌机罐体内有粘结的混凝土存料行驶中会产生噪音，要清铲干净。

6. There is adhesive concrete in the concrete mixer tank. Noise will be generated during driving. Shovel clean.
