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:
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.
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.
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.
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.
