Nitrogen Diaphragm (Part No. 3115182201) – Suitable for Atlas COP
1838 Rock Drill
The Nitrogen Diaphragm, part number 3115182201, is a crucial component designed for the Atlas Copco COP 1838 rock drill. It is used within the drill’s hydraulic accumulator system to absorb pressure fluctuations, reduce hydraulic shocks, and stabilize performance during high-frequency drilling operations.
Description
Made from durable, high-performance elastomer, this diaphragm separates the nitrogen gas from the hydraulic oil
in the accumulator. As pressure changes occur during the rock
drill’s operation, the diaphragm flexes to maintain system balance
and protect internal components from excess strain. This ensures smoother operation, consistent impact force, and longer service life for the drill.
