HP 154 045 68 Accumulator – What Is It?
The HP 154 045 68 accumulator mounts on the two outer sides of the rock drill. It is built to withstand high pressure and is charged with nitrogen gas. By acting as a stabilizing, balancing unit, it helps the drill stay on axis, which means faster collaring and improved penetration. As a result, the drill operates more efficiently over the long term.
Key Functions & Benefits
- Axis stability: Prevents the drill from deviating off-center during operation.
- Faster start to drilling: Enables the bit to engage rock more quickly.
- Sustained efficiency: Contributes to consistent performance and longer service life of the drill.
- High-pressure durability: Designed to operate under demanding hydraulic and pneumatic conditions.
- Nitrogen-charged damping: The nitrogen charge provides balance and shock absorption in heavy-duty drilling.
Where It’s Installed
The accumulator is installed on both sides of the rock drill body, working in tandem to balance loads and smooth pressure spikes during drilling.
