Diaphragm Material
Most replacement diaphragms are manufactured from:
1. NBR (Nitrile Rubber) or
2. HNBR (Hydrogenated Nitrile Rubber)
These materials provide:
1. High oil resistance
2. Low gas permeability
3. Good fatigue resistance under repeated high-pressure impacts.
Common Symptoms of a Damaged Diaphragm
When the diaphragm fails, the breaker may exhibit:
1. Reduced impact power
2. Slow or irregular hammer blows
3. Nitrogen pressure loss
4. Hydraulic oil entering the gas chamber
5. Excessive heat generation
6. Frequent seal failures.
