The solution to the sudden stop of the broken hammer in use
Broken hammers are generally installed on excavators and used in conjunction.
Broken hammers are generally installed on excavators and used in conjunction. They are used in crushing construction. It is a new technology. After continuous improvement and improvement by engineers, they are widely accepted and used all over the world for their superior performance, but it is inevitable that some failures will occur in use. The following is the solution to the sudden stop of the broken hammer in use.：
1. Improper replacement of bushing.After the broken hammer replaces the bushing, it fails to stop working. It does not strike when it is pressed down, and there is a strike action after it is slightly lifted.Due to the replacement of the bushing, the position of the piston is closer, causing some small directional control valves in the cylinder to control the oil circuit at the starting position has been closed, and the directional control valve stopped working, causing the breaker to stop working.
2. The accumulator components in the pipeline fall into the pipeline.During the inspection process, it was found that the deformed parts in the reversing valve were stuck in the reversing valve.
3. Reversing valve card.After the disintegration inspection of the broken hammer, it was found that the other parts were intact. After inspecting the reversing valve, it was found that its sliding and astringent were easier to break. After removing the reversing valve spool, you may find that there are already multiple strains on the valve body.
4. Oil inlet on the back cover.The broken hammer gradually weakens during the blow, and then stops the blow.Measuring nitrogen pressure.The pressure is too high. After it is released, it can strike, but soon it stops hitting, and the pressure becomes higher after the measurement.After the disintegration, it was found that the upper cylinder was filled with hydraulic oil, and the piston could not be compressed backwards, causing the breaker to fail to work.
The above is the inspection method for the broken hammer to stop working. After the failure occurs, you can check it in the above manner. In addition, the staff must ensure that the quality of the main parts such as the piston, the front part of the main body, the oil cylinder, and the rear part of the main body of the broken hammer is not bad.
