HM73

详细说明

Design Features:

n  Chamber seal (modular design), optional with housing and lid;

n  Segmented seal rings, radially cut, for easy replacement;

n  Split housing design, for easy replacement;

n  Very small operation gap - low leakage;

n  Dry running, no need liquid lubricated and cooling;

n  Self-adjusting seal rings;

n  Compensation of radial and axial shaft deflections;

n  No sealing components mounted on the shaft and hence no additional shaft vibrations;

n  Seal rings running contact-free - sliding faces and machine consume no additional power;

n  Balanced seal ring inside chamber;

n  According to the characteristics of the medium, the connecting ports of sealing gas, separation gas and vent gas can be collocated;

n  High reliability, maintenance-free operation.

Performance Capability:

n  Shaft diameter: 40 to 350 mm;

n  Operating pressure: vacuum to 2.0 MPa;

n  Operating temperature: -120°C to 400°C for carbon, max.225°C for PTFE compound;

n  Sliding velocity: max. 150 m/s for carbon, max. 40 m/s for PTFE compound;

n  Radial play: ± 1.0 to 5.0 mm;

n  Axial movement: theoretically unlimited;

n  Recommended wear guard: > 58 HRC.

Application:

n  Chemical industry; power plant technology; petrochemical industry; food processing industry; metal production and processing;

n  Medium-sized and large fans / blowers; bearing seals (gear box, motors); steam turbines; mixers, agitators, mills, dryer;

n  Gases; fumes and exhaust, solids containing, flammable, acid containing and toxic gases; (solids containing) steams / liquid mist; oil mist / penetrating oil.
