The correct operation method of large breaker

Apr 13, 2020

As one of the common accessories in construction machinery, large breakers have been widely used in various occasions. As we all know, large-scale breakers have poor environmental conditions in daily work, and mastering the correct usage of breakers can not only improve work efficiency, but also greatly extend service life and reduce failure frequency. Summarized the correct operation methods of several large breakers, and share them with you here.

1. Appearance inspection before operation of large breaker

Check the gap between the drill rod and its bush, and see if there is hydraulic oil seeping out. Once it is found that the breaker has hydraulic oil leakage, the damaged sealing ring should be replaced immediately.

2. Lubrication during operation of large breakers

The breaker should be lubricated before operation and within 2-3 hours of continuous operation. When beating butter, the breaker should be placed vertically, the fiber rod should be compacted, and it should not be suspended, so as to prevent the butter from entering the hydraulic system.

3. Appropriate breakdown force should be used for large crushing operations

Appropriate breakdown force should be used for crushing. If the breakdown force is insufficient, the hammering energy of the piston will not be able to effectively crush the stone, so that the reaction force of the hammering force will be transmitted to the hammer body and the hammer carrier, thereby damaging these components. If the breakdown force is too large, the machine may suddenly tilt at the moment of the crushed stone, and the crushing hammer will hit the stone violently, which will also cause the crushing hammer to be damaged. Therefore, during the operation of the hammer, always pay attention to the breakdown force of the hammer.
