Productum Overview

This heavy‑duty sigillum Calicis et diaphragma assembly is specially engineered for Epiroc 2238HD and 2238HD+ hydraulic rock drills. It serves as the core sealing component for accumulator and return-oil buffer systems, resisting frequent pressure fluctuations under harsh underground mining conditions.

Fabricatus ex materiali composito caoutchouc FKM renfortato per textilium fortis, hic componentis praebet excellentem resistentiam ad fatigam, durabilitatem ad cyclum pressionis, proprietates oleo-resistentes et anti-aetatis. Perfecte potest substituere partes sigillantes fabricae originalis, solvere defectus typicos ut pressio accumulatoris decrescens, vis impactus insufficiens et fuga hydraulica interna, et prolongare cyclum revisionis perforatoris lapidei sub operatione perforationis continua altae intensitatis. 。

Claves Venditionis Puncta

1. Exacta substitutio OEM 100 %

Plene compatibilis secundum dimensiones cum perforatoribus lapideis hydraulicis Epiroc 2238HD / 2238HD+. Congruit numeris partium OEM 3115233300 et 3115519000. Installatio directa sine ulla modificatione.

2. Materialis Compositi Renfortati per Textilium Altae Performantiae

Adopts fabric-reinforced imported FKM rubber base material. Excellent pressure-cycle fatigue resistance, hydraulic-oil corrosion resistance and aging-resistant property, stable operation within temperature range −25°C ~ 110°C, suitable for long-term underground severe working environment 。

3. Anti-Fatigue & Stable Pressure Holding Performance

Each piece undergoes strict pulsating pressure cycle testing under 28 MPa working pressure. Effectively prevents accumulator pressure loss, maintains steady impact energy of rock drill, avoids drilling power decay caused by diaphragm early rupture.

4. Integrated Matching Assembly

Complete set includes main cup-seal diaphragm and supporting auxiliary sealing rings. One-stop replacement reduces on-site assembly preparation work, shortens equipment downtime and cuts overall maintenance cost of drilling rig.

5. Rigida Fabricae Qualitatis Custodia

Omnis cup seal et diaphragma per inspexiones hermeticitatis aeris, pressionis pulsantis et aetationis acceleratae transit antequam ad munus mittantur. Ad normam originalis instrumenti perficitur et servitium continuum et fidele machinarum metallicarum garantit.

6. Orbis applicationis
