Reasons for frequent breakage of bolts of excavator breaker

2020-07-20

Excavator breaker is a device with a wide range of uses, but it is also a device with a relatively high loss rate. It is prone to wear and bolt breakage, which greatly increases the construction cost. After all, after the bolt is broken, it is barely welded. It is easy to break again later. In order not to delay the construction progress, replacing it with a new one is a good way to solve this problem, but is there any way to make the bolt less easy to break? Let's analyze the reasons for the breakage of the breaker bolts of the excavator together and see if we can find a solution to the problem from the reasons.

1. The guard plate is deformed;

2. The position that should be welded is not welded or welded firmly. In this case, it is easy to cause deformation, which will cause the bolt of the excavator breaker to break;

3. The product itself has quality problems, that is to say, if you buy inferior products, it seems not surprising that there will be a break in this case;

4. Because the stress of a single root is too large, the stress is uneven, and the operator does not check the equipment regularly, which is also a main reason for bolt fracture;

5. Caused by external forces;

6. Excessive pressure causes excessive vibration;

7. Improper operation, such as stamping blanks. There is a solution to this situation, which is to tighten the bolts every 20 hours;

8. The excavator breaker will produce strong vibration during the working process, and this vibration will also cause the bolts of the guard plate to loosen or even break.

The above is the analysis of the frequent breakage of the breaker bolts of the excavator. What equipment should be used carefully and cautiously, and the daily maintenance work should be done in order to make its service life longer. .
