Applicable Scope
Temperature:-40~260C;
Pressure: negative pressure~0.2MPa;
Linear Speed: V<150m/s;
Application Fields:Be used in compressors whose suction pressureis close to atmospheric pressure,such as ammonia gas compressor in fertilizer unit,and ethylene or propylene compressor in ethylene unit.
Design Feature
Applicable for condition that the sealed gas pressure is close to atmospheric pressure;
With inboard labyrinth,the primary sealing gas pressure can be increased,which ensure the primary seal in a condition of positive pressure difference.Furthermore,the inboard labyrinth decrease the flow of seal gas into compressor,improve compressor's efficiency.The secondary
seal acts as auxiliary seal for safety;The rotating ring floats axially,therefore it has good adaptability.
