  混凝土搅拌车的喇叭内部密闭的,属于汽车中小的部件,容易损坏,所以使用时一定要谨慎爱护,下面我们就来看看有哪些原因会导致混凝土搅拌车喇叭出现故障:
  The horn of the concrete mixer is closed inside and belongs to small and medium parts of the car, which is easy to be damaged. Therefore, care must be taken carefully when using. Let's see what causes the horn of the concrete mixer to malfunction:
  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 terminals: some of the internal electromagnetic coil enameled wire terminal connectors of the horn are crimped by aluminum metal rivets, which are not firmly welded. If the insulation paint on the enameled wire of the end is not treated cleanly or the rivets are not crimped firmly, it is easy to produce virtual connection fault, which leads to poor working of the horn. This kind of fault is caused by the quality of the horn, which can not be repaired. Only new parts can be replaced.
  密封不严易受潮:虽然混凝土搅拌车喇叭内部是密闭的,但如果密封不严清洗混凝土搅拌车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。
  Airtight and susceptible to moisture: Although the interior of the horn of the concrete mixer is airtight, if the airtight cleaning of the concrete mixer enters the fog or there is water vapor in the air of the interior space, the water vapor will easily cause the contact to be damp and unable to work normally.

  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,混凝土搅拌车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: if you press the horn for a long time, it is easy to cause the horn contact ablation and generate impedance, the current flowing through the electromagnetic coil is weakened, and the electromagnetic attraction of the concrete mixer car is decreased, which can not attract the armature to drive the diaphragm to vibrate normally, resulting in hoarse or even silent voice. However, when the horn is continuously honked, if the instantaneous strong current through the impedance can still work normally, it will be good or bad.
  以上就是今天要介绍的会使混凝土搅拌车出现故障的几个原因,了解了这些会使机器出现故障的原因后,我们在使用它时一定要保护好它的喇叭,避免以上的问题。
  The above are several reasons that will cause the concrete mixer to break down. After understanding the reasons that will cause the machine to break down, we must protect its horn when using it to avoid the above problems.
