Factors affecting the frequency of hammer blows

Time of issue: : 2020-09--17
The breaker uses the hydraulic system to promote the reciprocating movement of the piston to perform work and output striking energy to perform work. The common striking frequency errors of the breaker include no strike, intermittent strike, low strike frequency, and weak strike. So, what are the reasons for these phenomena? Let the breaker manufacturers take you to explore today: 1. The piston moves but does not strike. The main reason for this situation is that the drill rod is stuck. The drill rod can be removed to check whether the drill rod pin and the drill rod are broken or damaged. If necessary, observe whether the piston in the inner jacket is broken and the small piece of the drill rod is stuck. Otherwise, clean up in time. 2. There is not enough high-pressure oil to flow into the hammer without hitting: there is not enough high-pressure oil to flow into the hammer without hitting. 3. Piston stuck: Whether the piston is flexible by pushing and pulling by hand, if the piston cannot move flexibly, the piston and the guide sleeve have been scratched, the guide sleeve should be replaced, and the piston should be replaced if possible. 4. It cannot be hit when it is crushed, but it can be hit when it is lifted up a little: This situation may be caused by the wear of the inner sleeve, which needs to be checked and replaced. 5. Improper replacement of the bushing. After replacing the bushing, the breaker failed to stop working. It would not strike when pressed down, and would strike after being slightly lifted. After replacing the bushing, the piston position must be higher, causing some small reversing valve control oil passages in the cylinder to be closed at the initial position, and the reversing valve stops working and the breaker stops working. Need to adjust and replace the original or regular bushing.
