Meet API617 standard, adopt advanced fluid dynamic pressure groove design to ensure reliable sealing operation;
The use of a light-weight moving ring minimizes the impact of the seal on the dynamic performance of the compressor rotor. The moving ring adopts a floating structure design with metal parts for external circle protection to adapt to various complex working conditions.
Without intermediate comb teeth in tandem structure, the primary seal can withstand all process pressures, and the secondary seal is a safety seal that operates under low pressure. When the primary seal fails, it can withstand full pressure operation. Most of the medium leaked in the first stage is introduced into the torch and a small amount of process gas leaks into the atmosphere.
Sealed non-contact operation, energy saving, safety and environmental protection, reliable performance, simple operation, and life span of more than 5 years.
Pressure: 0 ~ 20MPa
Temperature: -180 ~ 280 ℃
Line speed: <200m / s
Applicable working conditions:
Applicable to various process gases, mainly suitable for medium and high pressure working conditions, such as cracked gas, synthesis gas, recycled hydrogen, recycled gas, natural gas, ethylene gas, propylene gas, raw material gas, etc. It is also suitable for working conditions where gas is expensive and needs to be recovered, such as helium, LNG, etc.
In the axial size is sufficient, the medium does not need to be recovered, the YTCG804 type is recommended.
