Product Description
- Return stroke: High-pressure hydraulic oil enters accumulator oil cavity, inwardly squeeze rubber cup, inner nitrogen is compressed, hydraulic energy converts into nitrogen compression potential energy and stored inside nitrogen chamber.
- Piston moves to top dead center for oil circuit reversal, high-pressure hydraulic oil switches into piston upper chamber.
- Power striking stroke: Compressed nitrogen expands instantly to push rubber cup reverse extrusion, stored hydraulic oil flows back into hydraulic loop to supplement instantaneous high flow, drive piston downward fast to hammer chisel.
- After single blow finished, hydraulic oil squeezes rubber cup again to compress nitrogen, circulate energy storage & release repeatedly.
- Bowl-type rubber cup always isolates nitrogen gas and hydraulic oil completely to avoid gas-liquid mixing and system pressure drop.
- Modified HNBR raw rubber physical & chemical performance detection
- Multi-stage closed rubber mixing & functional auxiliary even dispersion
- OEM precision mold constant temp & pressure seamless hot vulcanization forming
- Post-vulcanization curing standing for internal stress relief
- Full appearance sorting to eliminate pinhole, crack & defective products
- Random inflation air tightness + cyclic expansion fatigue testing
- Surface cleaning → individual PE vacuum seal → export carton packing
Q1: What’s the raw material of SB131 rubber cup?
A1: Premium modified HNBR hydrogenated nitrile rubber with anti-oil & high temp resistant formula.
Q2: What causes rubber cup nitrogen leakage in usage?
A2: Over-high pre-charged nitrogen pressure, long-time high temp aging or inferior raw material leading to inner crack & pinhole.
Q3: Can I order sample before bulk wholesale?
A3: Single sample is available, large quantity order gets tiered discount & priority delivery.
