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. The following small series will take you to see what causes the horn failure of concrete mixer truck?

混凝土攪拌車(chē)電磁線(xiàn)圈端子接觸不良：有些喇叭內部電磁線(xiàn)圈漆包線(xiàn)端子接頭是鋁金屬鉚釘壓接連接的，非牢靠焊接連接，如果端頭漆包線(xiàn)上的絕緣漆處理不凈或鉚釘壓接不牢靠很容易產(chǎn)生虛接故障，導致喇叭工作不良。此種故障是喇叭質(zhì)量原因，無(wú)法修復，只能更換新件。

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 leads 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.

混凝土攪拌車(chē)密封不嚴易受潮：雖然混凝土攪拌車(chē)喇叭內部是密閉的，但如果密封不嚴清洗混凝土攪拌車(chē)時(shí)進(jìn)入霧氣或內部空間空氣中有水蒸氣，水蒸氣很容易導致觸點(diǎn)受潮無(wú)法正常工作。

The concrete mixer is not tightly sealed and easy to be affected by damp: Although the interior of the horn of the concrete mixer is sealed, if the sealing is not tight, when cleaning the concrete mixer, there is mist or water vapor in the air in the internal space, and the water vapor is easy to cause the contact points to be damped and unable to work normally.
                

混凝土攪拌車(chē)觸點(diǎn)燒蝕：如果長(cháng)時(shí)間按喇叭易造成喇叭觸點(diǎn)燒蝕而產(chǎn)生阻抗，流過(guò)電磁線(xiàn)圈的電流減弱，混凝土攪拌車(chē)電磁吸力下降無(wú)法吸引銜鐵帶動(dòng)膜片正常振動(dòng)，導致發(fā)音沙啞、甚不響。但不斷按喇叭時(shí)，若瞬間強電流通過(guò)阻抗依然能正常工作，所以會(huì )時(shí)好時(shí)壞。

Contact ablation of concrete mixer: if the horn is pressed for a long time, it is easy to cause horn contact ablation and produce impedance. The current flowing through the electromagnetic coil is weakened, and the electromagnetic suction of the concrete mixer truck is reduced, which can 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.

了以上的喇叭問(wèn)題，接下來(lái)看看鬧心的噪音問(wèn)題吧。雖然都不是大問(wèn)題，但是都是要上心??！操作混凝土攪拌車(chē)的朋友都知道機器在操作中噪音很大，不知道怎么處理才正確，其實(shí)噪音大的綜合原因是決定噪音大的主要因素，下面介紹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! All the friends who operate the concrete mixer truck 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、濾芯堵塞也是會(huì )造成噪音大，處理方法是清洗或更換濾芯。

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會(huì )造成噪音的，需要更換低粘度的液壓油。

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、車(chē)油箱液面太低，油面上空氣被吸入泵內，補加相同標號的液壓油。

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、吸油管路進(jìn)氣或堵塞；檢查擰緊，不要吸進(jìn)空氣。

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

5、泵的安裝支架的剛性不足，工作時(shí)會(huì )產(chǎn)生震動(dòng)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、混凝土攪拌車(chē)罐體內有粘結的混凝土存料行駛中會(huì )產(chǎn)生噪音，要清鏟干凈。

6. There is adhesive concrete stored in the tank of the concrete mixer truck. Noise will be generated during driving, so the shovel should be cleaned.
