自动搅拌一体机的喇叭出现故障的方案？

所属分类：常见问题发布时间：2020-09-10 来源：http://www.shanqijituan.cn/ 浏览量：0

自动搅拌一体机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，下面详细的为大家介绍下。

The horn of the automatic mixing machine is equivalent to the mouth of human beings. If the horn fails, it can not make sound and attract other people's attention. The failure of the horn is mainly due to the electromagnetic coil terminal, loose sealing, easy to be affected by moisture, contact ablation and other reasons. When operating the concrete mixer truck, do not adjust the hydraulic system of the mixer truck at will. Before use, it is necessary to clean the water and sundries in the mixing drum. Before starting up in winter, it is necessary to check whether there is icing. The following is a detailed introduction for you.

一、自动搅拌一体机喇叭出现故障的原因

1、 The reason of the horn failure of the automatic mixer

1、电磁线圈端子不良

1. Bad terminal of electromagnetic coil

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。

Some horn internal electromagnetic coil enameled wire terminal connector is aluminum metal rivet crimping connection, which is not reliable welding connection. If the insulation paint on the end enameled wire is not clean or the rivet crimping is not reliable, it is easy to produce false connection fault, which will lead to poor working of the horn. This fault is due to the quality of the horn and can only be replaced.

2、密封不严易受潮

2. It is easy to get damp if the seal is not tight

虽然自动搅拌一体机喇叭内部是密闭的，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 inner part of the horn of the automatic mixing machine is sealed, if the sealing is not tight, when cleaning the concrete mixer truck, it enters into the fog or there is water vapor in the air in the internal space, and the water vapor is easy to cause the contact to get damp and can not work normally.

3、触点烧蚀

3. Contact ablation

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，多功能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 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 multi-functional 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.

二、自动搅拌一体机操作注意事项

2、 Operation precautions of automatic mixing machine

1、操作自动搅拌一体机注意液压系统压力应符合使用说明书中的规定，不得随意调整。液压油的油质和油量应符合原定要求。

1. When operating the automatic mixing machine, pay attention that the pressure of the hydraulic system should comply with the provisions in the operation manual, and should not be adjusted at will. The quality and quantity of hydraulic oil should meet the original requirements.

2、操作自动搅拌一体机注意装料前，应先排净拌筒内残存的积水和杂物。在运输过程中要不停的转动，以防混凝土离析。混凝土搅拌运输车到达工地和卸料之前，应先使拌筒全速以14—18转/分转动1—2分钟，然后再进行反转卸料。反转之前，应使搅拌筒停稳不转。

2. Before operating the automatic mixing machine, pay attention to drain the residual water and sundries in the mixing drum before loading. In the process of transportation, keep rotating to prevent concrete segregation. Before the concrete mixer truck arrives at the construction site and unloads, the mixing drum shall be rotated at full speed at 14-18 rpm for 1-2 minutes, and then reverse unloading shall be carried out. Before reversing, the mixing drum should be stopped stably.

3、环境温度高于+25摄氏度，从装料、运输、到卸料延续时间不得超过60分钟，环境温度低于+25摄氏度，上述时间不得超过90分钟。

3. If the ambient temperature is higher than + 25 ℃, the duration from loading, transportation to unloading shall not exceed 60 minutes; if the ambient temperature is lower than + 25 ℃, the above time shall not exceed 90 minutes.

4、冬期施工时，应切实做到：开机前检查是否结冰;下班时认真排除拌筒内及供水系统内残存积水，关闭水泵开关，将控制手柄置于“停止”位置。

4. During winter construction, it is necessary to check whether there is icing before starting the machine; when off duty, carefully remove the residual water in the mixing drum and water supply system, turn off the water pump switch, and put the control handle at the "stop" position.

5、在施工现场卸料完毕后，应立即用搅拌车随带的软管冲洗进料斗、出料斗、卸料溜槽等处，清洁粘附在车身各处的污泥及混凝土。在返回搅拌站的途中，应向搅拌筒内注150---200L水以清洗筒壁及叶片粘结的混凝土残渣。

5. After unloading at the construction site, the inlet hopper, discharge hopper and discharge chute should be washed with the hose attached to the mixer truck immediately to clean the sludge and concrete adhered to the vehicle body. On the way back to the mixing station, 150-200l water should be injected into the mixing drum to clean the concrete residue bonded by the cylinder wall and blades.
