Description
Product Description
The Steam Turbine Shaft Seal Fan is a key auxiliary device in the turbine shaft seal system, featuring low noise, a wide flow range, a flat performance curve, and high energy efficiency. The fan impeller is made of aluminum-magnesium alloy or 304 stainless steel, with a vibration amplitude of less than 0.05mm and a main body service life of up to 12 years.
Product Application
The shaft seal fan is mainly used in the turbine shaft seal steam cooler (shaft seal heater), drawing in the air-steam mixture leaking from the shaft seal to prevent steam from leaking from the shaft seal end into the turbine hall and oil system.
Product Features 1. High efficiency and energy saving, stable performance. The fan has a flat performance curve, a wide flow range, smooth operation, and significant energy-saving effect.
2. Reliable structure and strong adaptability. The product can be manufactured in both horizontal and vertical structures to adapt to different site installation requirements.
3. Excellent materials and reliable sealing. The impeller is made of aluminum-magnesium alloy (riveting process) or 304 stainless steel (welding process), the casing is galvanized for corrosion protection, and the hub and volute are treated with three layers of anti-rust paint.
FAQ
Q: How to select the correct model?
A: When selecting a model, the air volume, air pressure, and power parameters should be determined according to the technical requirements of the shaft seal heater. Improper selection, failing to meet the specified requirements and rated flow, may result in insufficient gas delivery pressure and gas leakage.
Q: How to handle gas leakage from the fan?
A: Common causes include excessive vibration due to a rigid connection between the inlet and outlet, and insufficient pressure due to improper model selection. It is recommended to switch to a flexible connection and recalculate the selection parameters.
