Hydraulic system requirements
The following is required for an optimum performance of the hydraulic rotary hammer drill:
- Provide a volume flow of 15 to 45 l/min at an operating pressure of max. 80 bar.
- The system should not have more than 17 bar back pressure.
- The hydraulic system should have sufficient heat rejection capacity to limit the maximum oil
temperature to 60° C at the maximum expected ambient temperature.
It is recommended:
That filter elements are sized for a volume flow of at least 114 lpm for cold temperature
startup and for maximum dirt holding capacity.
The hydraulic system should have a minimum of 10 to 25 micron of full-flow filtration.
