Pumps are critical components in industries like 石油和天然气, power generation, chemical processing, and marine operations.
A single leak can cause costly downtime, environmental risks, and safety hazards. To avoid these issues, mechanical seals must be durable and reliable.
Tungsten carbide seal rings are one of the most trusted solutions for leak-free pump operation. This article explains their properties, advantages, applications, and best practices for decision-makers.
Why Leak-Free Pump Operation Matters
Prevents fluid loss → Protects resources and reduces waste.
Maintains efficiency → Pumps perform better without pressure loss.
Reduces maintenance costs → Fewer failures mean fewer repairs.
Protects the environment → Prevents spills of hazardous materials.
Ensures safety → Avoids dangerous leaks near operators or equipment.
碳化钨密封环的性能
碳化钨是钨和碳的化合物，并与钴或镍结合。其特性包括：
极端 硬度 → Resists wear from friction and particles.
高抗压强度 → Handles heavy loads without cracking.
耐腐蚀 → Works well with chemicals, seawater, and oils.
热稳定性 → Maintains sealing performance under high heat.
尺寸稳定性 → Ensures precise sealing over long periods.
These properties help pumps stay leak-free under tough conditions.
钴结合碳化钨与镍结合碳化钨
1). 钴结碳化钨
Best for vibration-heavy or high-shock pumps.
Common in oilfield and mining operations.
2). 镍结碳化钨
Superior corrosion resistance.
Ideal for chemical plants, marine pumps, and wastewater systems.
Choosing the right binder ensures long service life and reliable sealing.
