Espey WD500
Merkmale
- Multi-part seal rings, overlapped mortised with gas tight Joints (adjusting)
- Split housing design
- Lowest possible operation gap - lowest leakage
- Dry-running
- Self-adjusting seal rings
- Seal rings bear radial shaft movements
- Compensates axial shaft movements
- Short axial installation length
- No sealing components mounted on the shaft and hence no additional shaft vibrations
Vorteile
- Easy installation by split housing design (shaft removal not required)
- Long-term operation time
- Maintainability
- Segmented seal rings for easy replacement
Einsatzbereich
Shaft diameter:
d = 45 ... 340 mm (1.77" … 13.89")
Operating pressure: p = vacuum ... 3 bar (44 PSI) abs. (depends on peripheral velocity)
Operating temperature: t = -120 °C ... +500 °C (-184 °F … +932 °F) for carbon
[700 °C (1,292 °F) for blast furnaces],
-120 °C ... +150 °C (-184 °F … +302 °F) for PTFE compound
Sliding velocity:
vg = max. 40 m/s (131 ft/s)
Radial play: ± 2.5 … 5.0 mm (± 0.1" … 0.2")
Axial movement: theoretically unlimited
Recommended wear guard: >58 HRC
