발전소 보일러 급수 펌프용 카바이드 씰 링

Power plants rely on boiler feed pumps to move water at very high pressure into boilers.

These pumps work under extreme heat, pressure, and continuous operation. Even a small seal failure can stop a unit, cause costly repairs, or reduce power generation efficiency.

카바이드 씰 링 have become the preferred choice for these pumps. They provide excellent 경도, 강인함, 그리고 내식성.

For decision-makers, using carbide seals means fewer shutdowns, safer operations, and better return on investment.

Challenges in Boiler Feed Pump Sealing

High pressure and temperature can deform or damage weak seals.
Continuous operation increases friction and wear.
Water impurities or chemical additives can corrode metal components.
Unexpected leaks can lead to boiler trips or turbine damage.

Standard materials like stainless steel or carbon graphite often fail quickly in these conditions.

Carbide seal rings are engineered to withstand such harsh environments.

Why Carbide Seal Rings Are Ideal for Power Plants

1) 극단적 경도

Carbide is nearly as hard as diamond, resisting scratches and abrasive particles in feedwater.

2). Strength and 강인함

Cobalt-bonded carbide survives pressure fluctuations and vibration common in boiler feed pumps.

3). 부식 저항성

Nickel-bonded carbide resists attack from water treatment chemicals or dissolved oxygen.

4). Thermal Stability

Carbide maintains its shape and performance under the high temperatures of boiler feed systems.

5). Long Service Life

Fewer replacements reduce downtime and maintenance costs.

Applications in Power Plant Systems

Boiler Feed Pumps

Primary pumps pushing water into boilers use carbide seals to maintain reliability.

Booster Pumps

Booster pumps feeding the main boiler pumps benefit from carbide’s durability.

Auxiliary Water Systems

Carbide rings in auxiliary pumps improve plant-wide sealing performance.

Real-World Examples

Coal-Fired Power Plant Upgrade

A coal plant replaced stainless steel seals with nickel-bonded carbide rings in its boiler feed pumps.

Result: seal life increased by 60%, and unplanned outages dropped significantly.

Combined Cycle Gas Plant Improvement

A gas-fired plant upgraded auxiliary boiler feed pumps with carbide seals.

Result: lower maintenance costs and more stable power output during peak demand.
