混凝土搅拌车喇叭出现故障怎么修?

来源:http://www.zkzdsljbc.com/ 时间:2021-08-06

电磁线圈端子不良
Poor solenoid terminal
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,只能换件。
The terminal joints of the enamelled wire of some horn internal solenoid coils are crimped and connected by aluminum metal rivets, which are not firmly welded. If the insulating paint on the end enamelled wire is not treated cleanly or the rivets are not firmly crimped, it is easy to produce virtual connection fault, resulting in poor operation of the horn. This failure is the cause of horn quality and can only be replaced.
密封不严易受潮
The seal is not tight and easy to be damp
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。
Although the interior of the horn of the concrete mixer truck is sealed, if the sealing is not tight, when cleaning the concrete mixer truck, it enters the fog or there is water vapor in the air of the internal space, which is easy to cause the contact damp and can not work normally.
触点烧蚀
Contact ablation
混凝土搅拌车
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。
If you press the horn for a long time, it is easy to cause the horn contact ablation to produce impedance, the current flowing through the electromagnetic coil is weakened, the electromagnetic suction of the concrete mixer is reduced, and the armature cannot be attracted to drive the diaphragm to vibrate normally, resulting in hoarse pronunciation or even no sound. However, when the horn is continuously pressed, if the instantaneous strong current passes through the impedance, it can still work normally, so it will be good and bad from time to time.
混凝土搅拌车的喇叭就相当于人类的嘴巴,如果喇叭出现故障,就无法发出声音,引起别人的注意,导致喇叭出现故障主要是因为电磁线圈端子密封不严易受潮触点烧蚀等原因。在操作混凝土搅拌车时,不要随意调整搅拌车的液压系统,使用前需要清洁搅拌筒内的积水及杂物,冬季开机前需要检查是否有结冰的状况,
The horn of the concrete mixer truck is equivalent to the mouth of human beings. If the horn fails, it will not be able to make sound and attract other people's attention. The failure of the horn is mainly due to the loose sealing of the electromagnetic coil terminal, easy to be affected by moisture, contact ablation and other reasons. When operating the concrete mixer, do not adjust the hydraulic system of the mixer at will. Clean the ponding and sundries in the mixing drum before use. Check whether there is ice before starting in winter,
