Power plants rely on cooling water systems to manage heat and keep turbines, pumps, and generators running safely.
Any leak or failure in these systems can lead to downtime, efficiency loss, or environmental damage.
Vòng đệm cacbua vonfram are one of the most reliable materials for pumps and compressors in cooling water systems.
This article explains why they are essential, their benefits, and how to use them effectively.
Why Cooling Water Systems Need Reliable Seals
Prevent leaks → Protect equipment and reduce water loss.
Maintain efficiency → Proper seals help pumps operate at full performance.
Reduce downtime → Reliable seals minimize unplanned maintenance.
Avoid contamination → Prevents cooling water from mixing with other fluids.
Protect the environment → Stops harmful discharges into natural water sources.
Tính chất chính của vòng đệm cacbua vonfram
Tungsten carbide is a compound of tungsten and carbon, bonded with cobalt or nickel. It offers:
Vô cùng độ cứng → Resists abrasion from particles in water.
Cường độ nén cao → Handles high pressure in large pumps.
Khả năng chống ăn mòn → Works well with treated or brackish water.
Độ ổn định nhiệt → Maintains sealing performance under temperature changes.
Tuổi thọ dài → Fewer replacements and lower maintenance costs.
Cacbua vonfram liên kết coban so với liên kết niken
1). Cacbua vonfram liên kết coban
Lớn hơn độ dẻo dai for pumps exposed to vibration or shock.
Common in large turbine cooling systems.
2). Cacbua vonfram liên kết niken
Thượng đẳng corrosion resistance.
Ideal for brackish or chemically treated water.
