Breaking hammer is very common for people engaged in excavator industry. The risk and difficulty coefficient of crushing operation requiring breaker are higher than those of ordinary operation. For excavator operators, selecting the appropriate breaker, using the breaker and maintaining the breaker are basic knowledge. However, in practice, the breaking hammer is often damaged and the maintenance time is long. From the article will be described through the following operations to extend the service life of the breaker, for reference only.
1. Inspection
The inspection of breaking hammer is the most basic and cautious thing. Many broken hammers fail because they are often ignored when there are slight abnormalities. For example, whether the high and low pressure oil pipes of the breaker have been loosened, and whether some pipelines have begun to leak oil, these details must be checked in place to prevent the oil pipes from falling off due to the high-frequency vibration of the crushing operation.
2. Prevent empty play
During the operation of breaker, many operators will think that the problem of empty beating of breaker is not serious. This wrong understanding will lead to the wrong operation. The drill rod does not always keep perpendicular to the broken object, does not press the object tightly, does not stop working immediately after breaking, and several empty strokes occur from time to time. The wrong operation of empty beating will cause the main body bolts to loosen, the front body to be damaged, and even the excavator to be damaged. Be careful.
3. The drill rod shakes
No matter how skilled the operator is, it is impossible to break without shaking a bit of drill rod, but such behavior must be minimized. Otherwise, the damage of bolts and drill rods is easy to accumulate and cause greater damage. In addition, bad operations such as falling too fast and pounding broken objects must be corrected in time.
4. Operation in cement sand
In places such as water or sediment, the probability of using breaker is small, but the possibility of construction under this working condition cannot be ruled out. At this time, except for the drill rod, the part of the breaker body cannot be soaked in cement sand. Because the breaker is composed of precision parts, such precision parts are most likely to seriously affect the performance of the piston due to ponding and soil, which will greatly reduce the service life of the breaker.
5. Continuous operation
Sometimes, when the project time is particularly urgent, the operator will continue to work continuously. When the breaking hammer works continuously on a hard object, the continuous breaking time at the same position shall not exceed one minute, mainly to prevent high oil temperature and drill rod damage.
6. Breaker pushes heavy objects
The operation of pushing heavy objects with the guard board of the breaker is often encountered in practical operation, but this behavior is very dangerous. On the one hand, it will damage the breaking hammer itself. On the other hand, if the model equipped with the breaking hammer is small, it will cause dangerous accidents such as broken arm and rollover of the machine.
Although the crushing operation will have a certain impact on the service life of excavator and breaker, according to the methods mentioned above, the service life of breaker is closely related to daily use and maintenance. If the broken hammer of the same brand is maintained and used in place, the probability of failure is far lower than that of not using in place.
