1. What factors affect a hydraulic hammer’s power?
The power of the hydraulic hammer is affected mainly by three factors: nitrogen pressure (back head pressure), hydraulic flow, and impact rate.
The amount of nitrogen is very specific; overcharging the nitrogen will make it stop hammering, while low nitrogen pressure results in weak hammering.
Hydraulic flow directly affects working pressure. Over-flow can damage the hammer very quickly, so be sure to work within the proper hydraulic range.
There is a frequency valve on the cylinder body responsible for the impact rate. Adjust it manually according to working conditions.
Basically, under certain working conditions, a slower impact rate leads to a more powerful impact, and higher frequency means a lighter blow.
2. How often does the seal kit need to be replaced?
It depends on working conditions, makes, and age. We recommend every three months.
3. Can a broken piston be repaired?
No, a broken hydraulic hammer piston can never
